Lipoleiomyoma
This is a 9 cm. mass in the uterine fundus which nearly completely replaces the anterior myometrium. Although the cut surface is firm, it has a distinct yellow, glistening appearance with a slightly "greasy" feel. The tumor bulges away from the thin rim of remaining surrounding myometrium. Of note, the surface is lobulated and does not appear "whorled" as would be seen in a typical leiomyoma. Microscopically, these tumors show an admixture of mature adipocytes and smooth muscle cells. At times, anomalous blood vessels may be present raising the differential diagnosis of angiolipoleiomyoma.
