Retroperitoneal hemangiomas large enough to have any clinical significance are so rare that practically no mention of the condition is made in standard textbooks on pathology. However, Stout1 in his volume on human cancer cites 2 instances, 1 a case of retroperitoneal hemangioma which was mistaken for a kidney, as reported by Harris, and the other a recurring lipoma which had areas of cavernous hemangiomas in it as described by Hilse. Of the few additional cases found elsewhere in the literature almost all are of renal origin. The present case of retroperitoneal cavernous hemangioma is presented because of its large size, its extrarenal origin and its rather unusual clinical picture and course.
