Description
Summary:This retrospective study describes 8 cases of intestinal hemangioma diagnosed in horses during postmortem examination or surgical biopsy at the University of Tennessee College of Veterinary Medicine. In all cases, the intestine was the sole organ affected, and lesions were focal (3/8) or multifocal (5/8). Nodules were most commonly within the small intestine (7/8), particularly the jejunum (5/7). One case was in the left dorsal colon, which is the first report of hemangioma in the large colon of a horse. Lesions were discrete, raised, smooth, black to red, and ranged from 2 to 15 mm in diameter. Microscopically, all lesions were cavernous type and mural, most frequently within the muscularis (6/8). A majority of cases occurred in middle aged to older horses (average age of 19.3 years), and no breed or sex predilections were identified. The hemangiomas were considered incidental findings.
