Adrenal myelolipoma size

Adrenal myelolipoma. Dr Mohammad Taghi Niknejad and Dr Yuranga Weerakkody et al. Adrenal myelolipomas are rare, benign and usually asymptomatic tumors of the adrenal gland characterized by the predominance of mature adipocytes. On imaging, they usually present as large masses with a variable amount of fat-containing components The size of adrenal myelolipomas is variable and can range from as few millimeters to greater than 10 cm when they are termed as giant adrenomyelolipomas. The largest adrenal myelolipoma reported to date weighed 6 kg. Extra-adrenal sites for myelolipomas include the retroperitoneum, thorax, and pelvis The adrenal mass consisted of a 93.84 g, 7.5 cm × 6.0 cm × 4.0 cm myelolipoma (Picture 2). The capsule was red-brown and smooth with areas of tan-yellow discoloration. The spleen weighed 230 g and measured 15.4 cm × 9.3 cm × 5.4 cm, displaying passive congestion and mild sinusoidal dilatation Materials and methods: We performed a comprehensive review of the literature using the PubMed database containing the key word adrenal myelolipoma. Results: We identified 492 articles written from 1956 to 2006 and reviewed 93 in detail including the authors' own experience. In this review, we highlighted the salient diagnostic features of. The median tumor size at discovery was 2.1 cm. Twelve (7.7%) tumors were >6 cm. Sixty-nine (46%) patients had a follow-up CT with a mean time interval between scans of 3.9 years. Eleven tumors (16%) grew over our follow-up period with a median growth rate of 0.16 cm/year. No patient developed a retroperitoneal hemorrhage

Adrenal myelolipoma Radiology Reference Article

Management of adrenal myelolipoma should be decided upon the size of lesion and presence of symptoms. Small lesions measuring less than 5 cm, and those who are asymptomatic are usually monitored via imaging over a period of one to two years 14) Adrenal myelolipoma is a rare, benign, mostly non functional tumor of adrenal gland, picked up incidentally on investigations for an unrelated pathology. Radiological features are diagnostic for this condition. While observation is recommended for smaller lesions, opinion is divided regarding management of larger lesions Myelolipoma, an uncommon benign neoplasm of the adrenal gland, is composed of adipose tissue and benign hematopoietic elements. Although myelolipomas are usually incidental findings, they vary considerably in size, and some are quite large; tumors larger than 30 cm in diameter have been reported Adrenal myelolipoma in association with Cushing's syndrome, Conn's syndrome, and congenital adrenal hyperplasia due to 21 alpha-hydroxylase or 17 alpha-hydroxylase deficiencies have been reported . Tumour size has been reported in literature from a few millimetres to more than 30 cm, but rarely exceeds 5 cm .They are mostly unilateral and do. Adrenal myelolipoma is uncommon and easily confused with malignancy when of large size (6 cm)

Myelolipomas are usually found to occur alone in one adrenal gland, but not both. They can vary widely in size, from as small as a few millimetres to as large as 34 centimeters in diameter. The cut surface has colours varying from yellow to red to mahogany brown, depending on the distribution of fat, blood, and blood-forming cells

Adrenal myelolipoma: To operate or not? A case report and

The operating time was 210 min and total blood loss 50-60 mL; no blood transfusions were needed. The patient was discharged on the third postoperative day. Histopathology confirmed an adrenal myelolipoma. The cited case is of the largest adrenal myelolipoma resected entirely using a laparoscopic approach It is considered a very rare case of retroperitoneal bleeding due to spontaneous rupture of a large adrenal myelolipoma [4] even though adrenal myelolipoma is the most common among benign adrenal soft tissue tumors [5]. Occasionally, they may cause symptoms like flank pain, secondary to compression from tumor bulk, necrosis, and hemorrhage Follow-up computed tomography scan in 2018 showed the right adrenal mass measuring 12.3 cm in greatest dimension with significant macroscopic fat. Given the imaging features, AM was the presumed diagnosis Adrenal myelolipoma is a rare benign tumor composed of adipose tissue and hematopoetic elements resembling bone marrow. The incidence of adrenal myelolipoma varies from 0.08 to 0.8% at autopsy . It is found incidentally during abdominal imaging study of patients It is commonly smaller than 4 cm in size upon initial identification with the largest reported adrenal myelolipoma measuring 31 cm × 24.5 cm × 11.5 cm and weighing 6 kg . We revisit this rare variant of lipoma of the adrenal gland that occurs in a 63-year-old female and discuss its literature review

Recommendations for the management of adrenal myelolipomas are predicated on size and symptomatology. For symptomatic myelo- lipomas or those larger than 7 cm, excision is advocated given the propensity of some lesions to grow significantly during the observation period and hemorrhage spontaneously or following minor trauma Incidence. Lipomatous tumours in adrenal glands are uncommon, with an incidence of 4-5% [7] in primary tumours involving the adrenal. Apart from myelolipoma, rare tumours such as lipoma, teratoma, angiomyolipoma, and liposarcoma are also found. Myelolipoma is the most common fatty tumour of the adrenal gland [10] Adrenal tumor size is an important determinant to help differentiate adrenal adenomas from nonadenomas; the majority of tumors less than 3 cm are benign, and the malignant adrenal lesions are generally more than 6 cm in size (11 - 20) Adrenal myelolipoma is a rare benign neoplasm composed of mature adipose tissue and a variable amount of hematopoietic elements. The incidence on autopsy has been reported from 0.08-0.4%. Most lesions are small and asymptomatic. An adrenal myelolipoma is consiidered a type of adrenal incidentaloma, which is a clinically unsuspected adrenal mass.

Adrenal myelolipoma: diagnosis and managemen

  1. Adrenal myelolipoma is composed of mature fatty tissue with variable amount of hematopoietic cells. Tumor size varies from a few millimeters to >30 cm. Adrenal myelolipoma is typically not.
  2. CT images were scored for the location and size of each myelolipoma and the presence of calcification, hemorrhage, fat, and pseudocapsule. Pathologic findings for the pattern of fat and bone marrow elements were correlated with CT findings. RESULTS: In 74 patients, 86 myelolipomas were found, of which 72 were in an adrenal gland (eight were.
  3. Adrenal myelolipoma is a rare benign tumor composed of an admixture of adipose and hematopoietic tissue. Most tumors are asymptomatic, small in size, right-sided, and usually detected incidentally. Though they are often smaller than four cm in diameter, they can reach larger sizes

Adrenal myelolipoma is a rare benign tumour of the adrenal. Most of the time these tumours are asymptomatic. When they are symptomatic they usually present with pain abdomen.

However it can be large and produce symptoms. The laparoscopic adrenalectomy is the gold standard for its treatment but can be challenging if the lesion is big because of technical aspects and the associated malignancy risk

The radiographically diagnosed adrenal myelolipoma: what

  1. Adrenal myelolipoma is an unusual, benign and biochemically inactive tumor that is composed of mature adipose and hematopoietic tissue. It is usually diagnosed accidentally and nowadays much more frequently because of widespread use of ultrasonography, computed tomography (CT) and magnetic resonance imaging
  2. Adrenal mass size is important for two more reasons. If the macroscopic fat content exceeds 50%, the diagnosis of adrenal myelolipoma can be confidently made [4]. It is safe to follow-up incidentally discovered, asymptomatic adrenal myelolipomas
  3. 8 Size • Masses > 6 cm - Greater >25% Malignant • Masses < 4 cm Are Generally Monitored •Q 6 month imaging x 2 •Q yr hormonal study x 4 • For Masses Between 4 and 6 cm: Criteria other than size should be considered in making the decision to monitor or to proceed to operation.

WebmedCentral > Case Report Page 2 of Fat-containing adrenal masses can be classified into two main types: those that contain intracellular fat (eg, adenoma) and those with macroscopic fat (eg, myelolipoma). Adrenal masses that contain intracellular fat have been shown to lose signal intensity on chemical shift out-of-phase images compared with in-phase images owing to the presence. Masses showing radiographic features of myelolipoma are considered benign. In addition, tumors smaller than 4 cm that are homogenous, with smooth margins, and that appear lipid-rich according to CT or MRI criteria are also usually benign. they should be performed using an adrenal protocol to determine size, heterogeneity, lipid content (MRI.

Myelolipoma is a benign mesenchymal tumor consisting of mature adipose tissue and hematopoietic cells. Tumors are most frequently localized to the adrenal gland, followed by the presacral region. Involvement of the mediastinum, lung, stomach, and kidneys has also been described [1, 2]. The overall frequency of myelolipoma at all locations is 0. Adrenal calcifications are seen in more than 25% cases and a significant proportion have haemorrhagic areas. 7 MRI is highly sensitive in identifying macroscopic fatty tissue components in an adrenal mass, which is pathognomonic of a myelolipoma. 8 However, very rarely, macroscopic fat on imaging has been seen in adrenal lipomas, teratomas.

Adrenal myelolipoma may also mimic angiomyolipoma of the kidney arising from the upper pole, but the reconstruction image of the multislice CT scan easily differentiates the origin., Treatment of an asymptomatic small adrenal myelolipoma (<5 cm) is usually conservative, with monitoring at 6-12 months intervals with ultrasound or CT scan Adrenal myelolipoma: a comprehensive review.

Adrenal myelolipoma causes, symptoms, diagnosis & treatmen

The myelolipoma is a rare, benign neoplasm composed of mature adipocytes and hematopoietic tissue. It was first described by Gierke in 1905 and subsequently by Oberling in 1929, who used the term myelolipoma [].In the past, the finding of adrenal lesions was made possible by autopsy or by clinical presentation, related either to the massive growth of the gland or to altered hormone production Myelolipomas usually originate in normal adrenal gland and are composed of variable amounts of mature fat and haematopoietic elements similar to bone marrow. [1, 2] In most cases they are asymptomatic and constitute an incidental finding. Adrenal myelolipomas range from 1-15 cm in size The incidental adrenal mass on CT: prevalence of adrenal disease in 1,049 consecutive adrenal masses in patients with no known malignancy. AJR Am J Roentgenol . 2008;190(5):1163-1168 The PubMed (Medline) and Cochrane Library databases were searched with the keywords - Adrenal Myelolipoma, Adrenal Incidentaloma and Adrenal Collision Tumor. A total of 547 relevant publications from 1954 to 2014 were reviewed. One hundred and forty-two publications were studied in detail

Giant adrenal myelolipoma is a rare, benign, sizable, mesenchymal tumor. Preoperative differential diagnosis from retroperitoneal liposarcoma may be challenging. A 66-year-old female patient was admitted because of a sizable tumor at the right retroperitoneal space, incidentally discovered during abdominal ultrasonography for screening purpose. Preoperative imaging studies were indicative for. In our scenario, the first case was the largest adrenal myelolipoma reported so far with 38 X 20 X 16 cm in size presented with severe anemia secondary to acute retroperitoneal hemorrhage. While, the second case was a large adrenal myelolipoma presented with severe sepsis secondary to abscess formation Adrenal myelolipoma is an uncommon, benign, biochemically non-functioning and endocrinologically inactive tumor composed of variable amounts of mature adipose tissue and scattered islands of haemopoietic elements, including erythroid, myeloid and lymphoid series, as well as megakaryocytes. Diagnosis of myelolipomas is based on imaging, with ultrasonography, CT and MRI being effective in more. Han M, Burnett AL, Fishman EK and Marshall FF.

Adrenal Myelolipoma—A Management Dilemm

  1. Myelolipomas are mesenchymal tumors which consist of mature adipose tissue admixed with hematopoietic cells [].This intriguing tumor most commonly occurs within the adrenal gland; however, it has occasionally been found within the pelvis, retroperitoneum, mediastinum, lungs, stomach, liver, spleen and kidneys [2, 3].Myelolipoma is a rare entity with incidence ranging from 0.08 to 0.4%.
  2. Background: Adrenal incidentaloma refers to the incidental finding of a tumor in the adrenal gland, where nonfunctional forms are the most common variant.Myelolipoma is a rare (0.08-0.4%) occurrence characterized by adipose and hematopoietic tissue. The aim of this case report is to describe the diagnosis and appropriate management of a myelolipoma in an asymptomatic patient, which was.
  3. Background. Adrenal myelolipoma represents a benign neoplasm consisting of mature fat interspersed with haematopoietic cells that can arise directly from the adrenal gland or in an extra-adrenal location.1 Adrenal myelolipomas have been associated with chronic stressors such as diabetes, hypertension, obesity, atherosclerosis, cancer and 21-hydroxylase deficiency.2 3 Despite the known.
  4. Myelolipoma is an uncommon tumor comprising adipose tissue and normal hematopoietic cells and mainly occurs in the adrenal cortex. Mediastinal myelolipoma is very rare; we report a case of posterior mediastinal myelolipoma that required surgical resection. A 56-year-old male was diagnosed with a posterior mediastinal tumor by computed tomography
  5. Adrenal myelolipoma is a rare variety of adrenal tumor with the prevalence of 0.08%-0.4% on autopsy, an incidence of 2%-4% of all adrenal tumors, and 10%-15% of all incidental adrenal masses. They are composed of mature adipocytes along with normal hematopoietic tissue
  6. Myelolipoma is a rare mesenchymal tumor consisting of adipose tissue and hematopoietic cells. Found usually in the adrenal region, however, few cases have been reported in extra-adrenal regions, most frequently in the presacral region. It is important to recognize such tumor, as it can attain massive size and causes pressure symptoms, and needs.
  7. ABSTRACT INTRODUCTION: Adrenal myelolipoma is a rare, non-functional, benign neoplasm which is constituted of mature haematopoietic elements and adipose tissues in various proportions. It is diagnosed accidentally and frequently with the widespread use of imaging modalities. PRESENTATION OF CASE: We report a 63-year-old lady with incidental findings of adrenal tumour on computed tomography (CT.

Discussion. Adrenal myelolipoma is a rare benign tumour with a prevalence of 0.08-0.2% that consists of mature adipose and hematopoietic tissue ().Myelolipoma was first described by Gierke in 1905, and was named 'formations myelolipomatoses' by Oberling in 1929 ().In the majority of the cases, it is incidentally diagnosed during clinical workup for other reasons METHODS: We reviewed the computed tomography (CT) reports of 62,279 patients evaluated at a tertiary referral center between 2002 and 2015 for the presence of an adrenal myelolipoma >1 cm in size. We then reviewed the CT imaging and patient charts to determine tumor size, growth, evidence of retroperitoneal hemorrhage, and endocrine dysfunction In autopsy series, adrenal masses larger than 0.5 cm in size are rather common (occurring in approximately 2% to 9% of people), and adrenal masses larger than 1 cm in size are found in 1.3% to 3.4% of patients who undergo abdominal or chest CT scans An adrenal incidentaloma is a mass lesion greater than 1 cm in diameter, serendipitously discovered by radiologic examination [ 1 ]. This entity is the result of technological advances in imaging such as computed tomography (CT) and magnetic resonance imaging (MRI) and their widespread use in clinical practice

Adrenal myelolipoma is a rare, benign tumor. Surgical resection is advocated in symptomatic cases, large (size >4 cm) cases, cases where there is an increase in size on follow-up, and cases with an atypical appearance on imaging Adrenal myelolipoma is an uncommon, benign, and hormonally non-functioning tumor that is composed of mature adipose tissue and normal hematopoietic tissue. Most cases to date are asymptomatic or have epigastric pain. Acute hemorrhage is the most dramatic manifestation of adrenal myelolipoma; though, it is a rare entity.

Tumorlike lesion of adrenal land composed of fat and bone marrow elements. Asymptomatic, patients usually in their 50s, rarely may present with flank pain and abdominal mass. Can also occur in the retroperitoneum. Gross: Non-encapsulated circumscribed bright yellow to white-tan, size considerably vary Adrenal myelolipoma is a rare condition. Although benign in nature, these tumors can increase in size and cause a mass effect to nearby structures presenting as abdominal distension and pain. In 90% of cases, adrenal myelolipomas are unilateral. However, the real challenge in management is when bilateral adrenal myelolipoma is present

In autopsy series, its prevalence is between 0.08% and 0.20%, with equal sex distribution [2]. It varies in size from microscopic foci to 8 cm in diameter. Giant adrenal myelolipoma is very rare clinical entity. Only rarely adrenal myelolipoma can grow large and can produce symptoms like abdominal pain and discomfort To date, <100 cases of giant myelolipomas have been reported. The large size of the adrenal myelolipoma in our case was partly due to hemorrhage. Typically, large myelolipomas may be associated with compressive symptoms; however, the most catastrophic complication is intratumoral hemorrhage, which may lead to retroperitoneal bleeding Adrenal myelolipoma is a very rare benign neoplasm usually unilateral, and nonsecreting, occurring in the adrenal gland which consist of fatty tissues and hematopoietic elements.Some cases of this type may cause symptoms like chronic abdominal pain however usually these tumors are small and asymptomatic. Surgery is the modality of treatment where there are severe symptoms with life threatening.

Background: Adrenal myelolipoma (AM) is a benign lesion for which adrenalectomy is infrequently indicated. We investigated operative indications and outcomes for AM in a large single-institution series. Subjects and Methods: A retrospective cohort study of prospectively collected data was conducted. Patients (≥16 years of age) who underwent adrenalectomy in the Division of General Surgery at. The proportion of myelolipoma in the adrenal tumors was 25.4% (genetically verified 36.6%). The median (range) age at tumor diagnosis was 36.0 (12 to 60) years and there were more tumors in males than in females (37.9% versus 22.1%; P<.05). In patients with myelolipomas, 93.5% had an undiagnosed or poorly managed CAH Myelolipoma. 3 (2) Adapted with permission from Cook DM, Loriaux DL. The incidental adrenal mass. Am J Med 1996; 101:88-94. TABLE 4 The size of an adrenal mass is important:. Extra-adrenal myelolipoma have been stated to have been reported in the retroperitoneum, pelvis, pre-sacral area, thorax, mediastinum, stomach, liver, and the thyroid gland . Beraha et al. [ 11 ] in 1974 reported a 64-year-old man who had arteriography to investigate his peripheral vascular disease which incidentally revealed a left renal mass

Objective: We aimed to describe clinical course of myelolipoma and to identify predictors of tumour growth and need for surgery. Design: A retrospective study. Patients: Consecutive patients with myelolipoma. Results: A total of 321 myelolipomas (median size, 2.3 cm) were diagnosed in 305 patients at median age of 63 years (range, 25-87) Adrenal myelolipoma is a rare mesenchymal tumour with benign biological behaviour that is mainly composed of mature adipose and myeloid tissue. Both sexes are equally affected, most commonly between the fifth and seventh or to a size >6cm. Giant myelolipomas (sized >10 cm) are rare.

There was no history of trauma and the swelling appeared to be an. Adrenal myelolipoma is a rare benign neoplasm consisting of mature fat and bone-marrow elements. Most lesions are small, unilateral and asymptomatic, discovered incidentally on imaging studies performed for other reasons or at autopsy. In recent years, larger, symptomatic myelolipomas have been successfully resected

Myelolipoma can occasionally be confused with a retroperitoneal liposarcoma that arises adjacent to the adrenal gland or an angiomyolipoma arising in the upper pole of the kidney; however, if one can confirm that the lesion actually arises from the adrenal gland, the diagnosis of myelolipoma should be made It could be an incidental association or there may be a common underlying pathologic basis. Here we report a rare case of adrenal myelolipoma in a 30-year old woman. Our case was unusual because of large size, symptomatic presentation and associated gall stones Adrenal Myelolipoma with Acute Hemorrhage: Isolated larger lesions (typically over 4 cm in size) Retroperitoneal hemorrhage; Extra-adrenal Myelolipoma: Myelolipomas occurring outside the adrenal gland Retroperitoneum (presacral or perirenal) Patients usually have no endocrine disorder or acute haemorrhage. Adrenal Myelolipoma with Associated. Myelolipoma is the most common fatty tumour of the adrenal gland. 4 The tumour is composed of mature adipose tissue and haematopoietic elements, and the tumour is thought to arise from metaplasia of undifferentiated stromal cells. 12 Reports on large series of patients with adrenal myelolipomas are lacking

During a five-year period, the size of the right adrenal gland was found to have grown. Imaging analysis confirmed the existence of small, new lesions in both pituitary glands. This case confers valuable information about the clinical course of adrenal myelolipoma associated with Cushing disease, the researchers said Adrenal myelolipomas are rare, hormonally inactive, benign neoplasms composed of mature adipose and hematopoietic tissues. Gierke1 first described these lesions in 1905, and Oberling2 coined the term myelolipoma in 1929. Myelolipoma commonly presents as an isolated adrenal lesion, although myelolipomatous foci have been reported in association with various other adrenal pathologic conditions. Extra-adrenal myelolipomas are rare benign tumours. Other soft tissue tumours such as well-differentiated liposarcomas appear morphological almost identical. Preoperative imaging and especially biopsy are important tools to diagnose these lesions. We report a very seldom case of a simultaneous myelolipoma of the adrenal gland in association with an extra-adrenal myelolipoma in an 75-year-old man

patients with presacral myelolipoma do not have follow-up imaging because of the benign nature of the lesion. However, the lesion's size ranges from 3.5 to 26 cm, with a mean size of 8.9 cm [10, 11]. These masses can continue to grow and may undergo necrosis and hem-orrhage [10]. Prognosis is generally excel The typical adrenal myelolipoma appears as an adrenal lesion with fat-containing components. The mass is usually relatively well circumscribed, however masses that are mostly fat may be difficult to separate from surrounding retroperitoneal fat Adrenal myelolipoma. a. Sagittal sonogram of the right upper quadrant demonstrating an enlarged, diffusely echogenic right adrenal gland. b.

We investigated operative indications and outcomes for AM in a large single-institution series. Subjects and Methods: A retrospective cohort study of prospectively collected data was conducted 3 Discussion. Adrenal myelolipoma is mostly a unilateral tumor without symptoms of endocrine disorder, with bilateral masses occurring in about 10% of cases. [8,9] In 1886, Arnold first reported myeloid tissue in the adrenal gland [10] and in 1905, Gierk described it as a tumor which has both adipose and hematopoietic tissue. [11

The suggested radiological differential diagnoses were: liposarcoma, teratoma and myelolipoma Adrenal myelolipoma is usually of small size (<5cm) and asymptomatic tumor. Also, large sizes may be dis-covered accidentally [4]. It is commonly diagnosed in old ages, and, mostly, without malignant potentials [1,3,5]. Biochemical activities and association with tumors in other organs of the body have bee surgery for the treatment of large adrenal myelolipoma [12]. Despite that, our decision for transabdominal open surgery was undertaken regarding the size of the tumor and easier approach to large vessels surrounding the tumor itself.

Adrenal myelolipoma: A 10‐year single‐center experience

Benign adrenal tumors that develop in the cortex are also called adrenal adenomas. Those that develop in the medulla are also called pheochromocytomas (fee-o-kroe-moe-sy-TOE-muhs). Most benign adrenal tumors cause no symptoms and don't need treatment. But sometimes these tumors secrete high levels of certain hormones that can cause complications Adrenal myelolipoma is an unusual, benign, and biochemically inactive tumor that is composed of mature adipose and hematopoietic tissue. The presence of mature bone spicules within the lesion is extremely rare. Very limited number of cases of myelolipoma containing bone tissue has been reported in the world literature. The size of the tumor. Adrenal Myelolipoma is a rare nonfunctional adrenal tumor usually detected incidentally on imaging done for un-related cause or due to compressive symptoms or rarely due to adrenal hormone hyper secretion or malignant transformation.A case of 35 years old male was complained with non-specific pain in right thigh for one month duration without history of trauma, musculoskeletal or neurological.

Gross photograph of a adrenal and juxtadrenal tumor. The specimen consists of cut sections of a adrenal gland (upper) and a juxtadrenal mass (A,B). The microscopic section of juxtadrenal schwannoma Adrenal adenomas often make aldosterone, but adrenal cancers rarely do. Symptoms caused by a large adrenal cancer pressing on nearby organs. As an adrenal cancer grows, it presses on nearby organs and tissues. This may cause pain near the tumor, a feeling of fullness in the abdomen, or trouble eating because of a feeling of filling up easily

A needle biopsy of an adrenal cancer also can actually spread tumor cells. For these reasons, a biopsy is generally not done before surgery if an adrenal tumor's size and certain features seen on imaging tests suggest it is most likely cancer. Blood tests of hormone levels and imaging tests are more useful than biopsies in diagnosing adrenal. Adrenal myelolipoma is a rare, non-functional, and benign neoplasm of the adrenal gland. 27 So, the management is based on the size and the symptoms of the tumor. 28. We report a case series with three cases of adrenal tumor. The first case is an adrenal cortical adenoma suggestive a functional type. The second case is a pheochromocytoma.

Adrenal myelolipoma (AML) is a rare, benign tumor in the adrenal gland. AML has no possibility to be malignant. The cause of AML is unknown currently. According to some studies, adrenal medulla or cortical cells can differentiate into fat and bone marrow hematopoietic tissue under the provocation of certain factors which can lead to AML
