Extra-adrenal Myelolipoma: Tumour at Unusual Site.

Abstract

A myelolipoma is a rare, well circumscribed, benign tumour composed of mature adipose and haematopoietic tissue. Classical location is adrenal gland but extra-adrenal cases are also reported in the presacral region, liver, mediastinum, perirenal, stomach with most common site being the presacral area. Only few cases of extra-adrenal myelolipoma have been reported in literature till now with an incidence of 14% of all myelolipomas. Differential diagnosis includes liposarcoma, teratoma, and extramedullary haematopoiesis. Histopathological diagnosis plays a major role in confirmation but also requires concordance of CT, MRI, and Guided biopsy. Extra-adrenal myelolipomas are very rare and their presence and location can be easily confused with malignant tumour. We present this case in a 54-year-old male with mass per abdomen and weight loss since one year.
