Myelolipomas are benign tumor composed of mature and immature hematopoietic elements without histologic alterations admixed with mature adipose tissue in different proportions. Symptoms are only present in one half of the patients consisting in abdominal pain, hematuria, palpable mass and hypertensión. Myelolipomas occur most often in the adrenal glands. Presacral extraadrenal location is rare. The differential diagnosis is prompted clinically with other retroperitoneal benign and malignant tumors and histologically with extramedullary hematopoiesis. We present the case of a 54 year old patient with an asymptomatic myelolipoma of presacral location.
