Uterine angioleiomyomas: a report of 3 cases of a distinctive benign leiomyoma variant.
We report 3 cases of a distinctive uterine leiomyoma containing numerous thick-walled vascular channels, which we term angioleiomyoma. The leiomyomas occurred in women aged 33, 44, and 49 and ranged from 1.5 to 6.0 cm. They were composed of bland, spindle-shaped cells with numerous evenly distributed, arteriole-like vessels with thick muscular walls throughout. The spindle cells often swirled around the vessels. In 1 case, fibrin was present within vessel walls. The spindle cells were positive with smooth-muscle markers and negative with HMB45. We believe angioleiomyoma should be recognized as a distinct entity and included in the World Health Organization classification of tumors of the female genital tract as a benign leiomyoma variant, similar to cellular and atypical leiomyoma. Uterine angioleiomyoma has a close morphological resemblance to the similarly named skin tumor. We review uterine smooth-muscle and other mesenchymal neoplasms in which prominent vascular channels are a feature.
