In recent years many cases of adrenal tumors originating in the cortex or medullary portion of the gland have been reported. In the presence of an abdominal mass and clinical signs of adrenal hyper-activity a tentative diagnosis of adrenal tumor may be made. Nonrenal retroperitoneal tumors may be (1) parietal retroperitoneal tumors arising from the walls and mesothelial structures of the retroperitoneal space or (2) unattached retroperitoneal tumors usually arising from the mesonephron or the gonad. A case is reported in which a retroperitoneal tumor, probably arising from the adrenal gland, displaced the gall-bladder to the left upper abdominal quadrant and the right kidney below the left kidney. The viscera, gallbladder, and right kidney returned to their normal positions after the tumor was removed. The site of origin was difficult to determine from the gross and microscopic study of the tumor.
A woman, aged 74, was admitted to the clinic on December 11, 1944 complaining of a painful mass in the right side of the abdomen.

She was forced to go to bed frequently because of weakness. The patient had no other complaints.
Physical examination revealed a fairly well nourished woman. The size and shape of the abdomen. . .
