Anterior Mediastinal Myelolipoma: A Case Report and Review of the Literature.

Am J Case Rep 2022 May 26;23:e936005. Epub 2022 May 26.

Department of Surgery, College of Medicine, King Fahd Hospital of the University, Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia.

Overview of the 2022 WHO Classification of Adrenal Cortical Tumors.

Endocr Pathol 2022 Mar 14;33(1):155-196. Epub 2022 Mar 14.

Department of Oncology, University of Turin, Turin, Italy.

Adrenal Myelolipoma Mimics Ectopic Adrenal or Renal Tissue: An Incidental Finding During Cadaveric Dissection.

Acta Endocrinol (Buchar) 2021 Apr-Jun;17(1):111-116

All India Institute of Medical Sciences, Department of Pathology, Patna, Bihar, India.

Context: On naked eye examination adrenal myelolipoma (AML) tissue appears to be an ectopic adrenal or renal tissue, based on the similarity to their external texture. This necessitates a histo-pathological study for confirming the origin of the tissue.

Objective: To establish the origin and histological features of the incidental AML tissue found during cadaveric dissection and review the literature for similar findings with clinical picture and treatment description. Read More

Adrenal myelolipomas.

Lancet Diabetes Endocrinol 2021 11 24;9(11):767-775. Epub 2021 Aug 24.

Department of Endocrinology, Karolinska University Hospital, Stockholm, Sweden; Department of Molecular Medicine and Surgery, Karolinska Institutet, Stockholm, Sweden.

Adrenal myelolipomas are benign, lipomatous tumours with elements of myeloid cells, most of which present as adrenal incidentalomas and comprise 3·3-6·5% of all adrenal masses. Adrenal myelolipomas are usually unilateral (in 95% of cases), variable in size, most often found during midlife, and affect both sexes almost equally. On imaging, adrenal myelolipomas show pathognomonic imaging features consistent with the presence of macroscopic fat. Read More

Adrenocortical adenoma with myelolipomatous metaplasia: a potential diagnostic pitfall: a case report and review of the literature.

J Med Case Rep 2021 Jul 4;15(1):333. Epub 2021 Jul 4.

Department of Pathology, Shiraz Medical School, Shiraz University of Medical Sciences, Shiraz, Iran.

Background: Adrenal incidentalomas are often found during investigation for another tumor or unrelated problems. Except for adrenal myelolipoma (second most common primary adrenal incidentaloma following adrenocortical adenomas), adrenal lipomatous tumors are uncommon generally and are often described as case reports in the literature. Since the amount of fat is variable, without the help of advanced imaging techniques, some adrenal lipomatous tumors may be misdiagnosed before pathologic examination. Read More

Incidentally discovered myelolipomatous adrenal adenomas, including six cases presenting with hypercortisolism.

Pathol Res Pract 2021 Aug 6;224:153508. Epub 2021 Jun 6.

Department of Pathology, Indiana University, Indianapolis, IN, 46202, USA.

Most adrenal incidentalomas are non-functioning adenomas that require no treatment. The presence of a myelolipomatous component of adrenal incidentalomas is a rare, but well-known occurrence in both hyperplastic and neoplastic lesions of the adrenal cortex. Although the improvements in abdominal imaging have increased identification of myelolipomatous adrenal cortical adenomas radiologically, due to the rarity of this lesion, the clinical pathological features of these lesions are unclear and can sometimes cause diagnostic difficulty.

Myelolipoma of Kidney: A Rare Extra-Adrenal Tumor in an Unusual Site.

Int J Appl Basic Med Res 2021 Jan-Mar;11(1):60-62. Epub 2021 Jan 26.

Department of Urology, Muljibhai Patel Urological Hospital, Nadiad, Gujarat, India.

Myelolipoma of the kidney is a very rare benign disease which is composed of mature adipose tissue admixed with mature hematopoietic elements in varying proportions. The most common location of myelolipoma is in the adrenal glands, but extra-adrenal myelolipomas in other locations such as the retroperitoneum, presacral region, pelvis, and mediastinum has also been reported. In this case report, we present a case of huge extra-adrenal myelolipoma in renal parenchyma which is rare site for its origin. Read More

Multiple enlarging hepatic and retroperitoneal myelolipomas in the setting of Cushing disease.

BMJ Case Rep 2021 Feb 23;14(2). Epub 2021 Feb 23.

Department of Radiology, University of Utah Health, Salt Lake City, UT, USA.

Myelolipomas are benign tumours typically occurring in the adrenal glands, made up of fat and trilineage haematopoeitic cells resembling bone marrow. Their aetiology is not well understood; however, they have a clear association with elevated serum adrenocorticotropic hormone (ACTH). Extra-adrenal myelolipomas are rare, and to our knowledge there are no previously reported cases of multiple enlarging hepatic and retroperitoneal myelolipomas in the setting of Cushing disease.
