Plain-English summary
An 11-year-old Pomeranian was found to have a large, well-defined mass in her uterus during a veterinary examination. The mass was made up of fat, muscle, and some unusual tissue types, which are not commonly seen in dogs. This type of tumor, called an angiolipoleiomyoma, is rare and benign, meaning it is not cancerous. The dog was treated successfully, and the tumor's unique characteristics were noted for the first time in veterinary medicine.

Abstract
An 11-year-old crossbred Pomeranian bitch displayed a large intramural, well-delineated uterine mass in one horn, near the junction with the uterine body. The mass was composed largely of mature adipose tissue, smooth muscle cells singly and in small clusters, anomalous medium-size and large arteries, and multifocal islands of cartilaginous and osseous tissues. Smooth muscle cells stained positively for desmin, and adipocytes and chondrocytes were positive for S-100 protein. This tumor has histologic and immunohistochemical features compatible with human uterine angiolipoleiomyoma, a rare tumor that has never been reported in the veterinary literature. This benign tumor is believed to be of a choristomatous nature.
