Vascular leiomyoma of the mesentery in a dog.
A 4-year-old male, miniature Schnauzer dog showed two large masses in the mesentery at necropsy. Histological examination of both masses revealed plain smooth muscle tumour cells intermingled with thick-walled blood vessels. The bundles of tumour cells often extended from the periphery of the vessels. Mitotic figures were rare. From these findings, the tumour was diagnosed as a vascular leiomyoma (angiomyoma), previously unreported in animals. The term, vascular leiomyoma, was proposed to describe this tumour in order to avoid confusion with hamartomatous angiomyoma.
