DISCUSSION

Myelolipomas are benign tumors composed of variable amounts of mature fat and hematopoietic elements, typically found in the adrenal gland. These are relatively rare, with an estimated incidence at autopsy in the range of 0.08-0.8%.[1] The largest myelolipoma of 34-cm diameter and weighing 5,900 g was described by Boudreaux et al.[1] The second largest (diameter 30 cm, weight 5,500 g) was described by Wihelmus et al.,[2] and the third largest (diameter 30 cm, weight 4,370 g) reported by O’Daniel-Pierce et al.[3] The present case manifested with huge abdominal mass measured 30× 20× 18 cm and weighed 3,000 g. Histopathological evaluation revealed islands of adrenal cortex (zona glomerulosa) scattered in between the adipocytes and hematopoietic islands.
