MYELOLIPOMA of the adrenal is a tumor arising in either the cortex or medulla of the adrenal, composed of fat and hematopoietic tissue resembling that found in bone marrow. It is a well-defined tumor mass without a true capsule, although compressed adrenal cortex tissue is usually seen surrounding the tumor giving the appearance of encapsulation.
Such fat and hematopoietic tissue tumors were first recognized by Gierke1 in 1905 and were given the name of myelolipoma by Oberling2 in 1929. Plaut,3 in 1958, reported 50 cases from the Armed Forces Institute of Pathology and a similar number from the literature. These were all discovered at autopsy as incidental findings. The tumor usually measured less than 4 cm in diameter and caused no apparent clinical symptoms. Asuncion,4 in 1965, found 144 cases of myelolipoma in the literature, all discovered at autopsy.
