Uterine leiomyoma with a focus of fatty and cartilaginous differentiation.
A uterine leiomyoma with a focus of fatty and cartilaginous differentiation in a 58-year-old female is reported. The leiomyoma was located in the posterior uterine wall and had a maximum diameter of about 15 cm. A yellow hard nodule, about 5 cm in diameter, was found in the periphery of the leiomyoma and histologically was composed of cartilaginous tissue in islands with lipofibromyomatous tissue surrounding them. Generally so-called lipomatous lesions of the uterus include circumscribed or diffuse lipomatosis of a leiomyoma and pure lipoma. Although appearance of cartilaginous tissue in lipomatous lesions of the uterus has never been reported, this case should be a very special form of circumscribed lipomatosis of a uterine leiomyoma.
