Bone Tissue in Adrenal Myelolipoma: A Case Report

This paper describes a case of adrenal myelolipoma with an unusual characteristic: the presence of bone spicules. The lesion was associated with an accessory adrenal gland containing foci of myeloadiposis. The authors believe that myelolipoma and myeloadiposis are closely associated and are in fact the expression of a single process that is both focal (myeloadiposis) and diffuse (myelolipoma). The process consists of the differentiation of choristomatous primitive mesenchymal cells into hematopoietic tissue, adipose tissue and, in rare cases, bone tissue.

Post Operative Complications

Myelolipoma is a combined lesion involving mature adipose tissue and bone marrow elements. Adrenal gland is the commonest site of myelolipoma. Usually these lesions are asymptomatic, unilateral and small in size. Occasionally myelolipomas become enormous and symptomatic depending on the location. Here we describe a case of bilateral giant adrenal myelolipoma presenting with abdominal pain. The case was managed surgically without any post-operative complications.

Mature Adipose Tissue

Myelolipoma of the adrenal gland is an unusual, benign tumour which is composed of mature adipose tissue and hematopoietic elements, similar to those of bone marrow. The tumour is hormonally inactive and unilateral although four cases in which the tumour has been found bilaterally have been reported. Extra adrenal myelolipoma has also been reported in the kidney, the liver and the presacral area. We present the case of an asymptomatic adrenal myelolipoma in a 68-year-old man, which was surgically removed.

Palpable Abdominal Mass

Adrenal myelolipomas are rare benign tumors. Most are detected incidentally on imaging for non adrenal relatedsymptoms. We report a case of a 78 year old female who presented with non- specifi c complaint of itching all over the bodyand a palpable abdominal mass. CT scan abdomen revealed a large right-sided retroperitoneal mass with thin capsulemeasuring 20.8x15.4x12.7cm. Differential diagnoses considered were retroperitoneal liposarcoma, retroperitonealteratoma and retroperitoneal myelolipoma. The tumor was resected and sent for histopathological examination.Microscopic examination revealed mature adipocytes, islands of hematopoietic tissue and compressed adrenal tissue atthe periphery clinching a diagnosis of adrenal myelolipoma.DOI: http://dx.doi.org/10.3126/jkmc.v2i1.10554Journal of Kathmandu Medical College, Vol. 2, No. 1, Issue 3, Jan.-Mar., 2013, Page: 33-35
