HEMANGIOSSARCOMA EM OVÁRIO DE CADELA: RELATO DE CASO

Abstract

Canine hemangiosarcoma (HSA) is a malignant neoplasia of blood vessels. It presents an aggressive and infiltrative behavior, which can manifest itself in a cutaneous form and with high metastatic power when in its visceral form. We report a case of a canine patient, female Golden Retriever, treated at a private veterinary clinic in the city of Teófilo Otoni-MG. Based on the clinical investigation, laboratory and imaging tests, uterine enlargement and the presence of a mass in the abdominal cavity were observed. Celiotomy was performed for ovariosalpingohysterectomy (OSH) and excision of the mass. This affected the left ovary, and its complete excision was performed using the technique of therapeutic approach to the uterus. The mass was submitted to histopathological analysis. In microscopic examination, neoplastic proliferation of mesenchymal cells was observed diffusely invading the sampled tissue and multifocal lymphoplasmacytic infiltrate. Based on the histopathological findings, a diagnosis of SAH in the left ovary was confirmed. Reports of hemangiosarcoma in ovaries are scarce, but they should be considered as a differential diagnosis. The objective of this essay is to contribute to the scientific academic community of Veterinary Medicine.
