Giant adrenal myelolipoma: case report and review of the literature.

Adrenal myelolipomas are rare tumors that consist of mature fat and bone-marrow elements. The majority that have been reported are small, asymptomatic lesions incidentally observed at the time of autopsy. In recent years, larger, symptomatic myelolipomas have been successfully resected. We studied the case of a giant adrenal myelolipoma in a 70-year-old woman. She was obese, hypertensive, and had abdominal pain, findings frequently associated with these lesions. Unusual features included formation of prominent bony spicules, a 52-year history of an abdominal mass, and massive size (5,500 g). To our knowledge, it is the largest myelolipoma yet reported.
