KIDNEY - Leiomyoma

The specimen is a right kidney which has been sectioned longitudinally. Situated in the pelvis there is a solid pale tumour mass. This has a whorled appearance and contains a central area of cystic degeneration. The tumour compresses the renal pelvis and extends to the vicinity of the renal hilum. Microscopic examination of the tumour showed it to be a leiomyoma.
The tumour was an incidental finding at post mortem examination of a 45 year old male who had died of acute myocardial infarction.
