ANGIOMYOLIPOMA OF THE PELVIS REPORT OF A RARLY BUTTOCK MASS

Abstract

Angiomyolipoma (AML) is a benign tumor, most common in the kidney, less in the liver, and rarely found in other organs. Pelvis angiomyolipomas are rare and may reach large size, and found in unusual organs. Our report describes a case of giant pelvic retroperitoneal AML in a female patient had suffered from numbness and tingling in her right lower limb for one year and presented as a buttock mass that becomes larger with cough and standing. Complete excision required laparotomy in the lithotomy position with an assistant incision in the buttock. The histopathological examination confirmed the diagnosis. This is the first published case in terms of pelvic location with a buttock mass presentation. This tumor should be taken in consideration of the pelvic mass approach.
