Sažetak
Hemangiosarcoma (HSA) is a malignant tumor of endothelial cells which occurs most frequently in old dogs. HSA may arise in any site of the body, but most common primary sites in dogs are spleen, skin/subcutis, right atrium and liver. Although primary colonic HSA in a dog has been described, literature survey, to the author's best effort, showed no data of small intestine HSA so far. We report the first case of small intestine HSA in a dog. An 11 year old male mixed breed dog was admitted to the veterinary clinic because of poor general condition. After X-ray and ultrasound examination which showed an abdominal mass approx. 9x5 cm in size, mass excision and enterectomy was performed. The excised mass was round and dark red-black hemorrhagic in appearance. Histopathologically the tumor consisted mostly of atypical neoplastic vascular spaces of various sizes lined by endothelial cells with cytologic atypia located in lamina muscularis externa of the small intestine. In the solid parts of the tumor, anaplastic endothelial cells were plump, spindle to ovoid with prominent nuclei. Marked anisocytosis and anisokaryosis with many bizarre nuclei were found. Mitoses were rare. Lymphocytic infiltrates were observed multifocally. Immunohistochemical staining confirmed cytoplasmic expression of CD 31 in endothelial cells. Since there were no lesions found in spleen during surgical procedure and no hepatic or cardiac lesions observed in X-ray and ultrasound, our finding suggests a primary small intestine HSA in a dog which is, to the author's knowledge, reported for the first time.
