SUBCUTANEOUS HEMANGIOMA IN ASSOCIATION WITH ECTOPIC PULMONAR TISSUE IN NEWBORN BOVINE.

Abstract

Congenital skin neoplasms are rare in cattle. However, when observed, hemangioma, a vascular benign tumor of origin, is worth mentioning. Its association with tissue of distinct embryologic origin resulting from ectopic processes is not commonly reported. Accordingly, this study aimed to describe a congenital hemangioma with the presence of pulmonary ectopic tissue in a calf. A male calf, mixed breed, with four hours of life, was received with a history of neoformation close to the anus. The patient underwent physical examination and surgery for the excision of the neoformation. The material obtained was sent for histopathological analysis. The tumor, located in the perianal region, was subcutaneous, and had 25 cm in diameter. The cutting area showed the existence of ectopic pulmonary tissue. Histopathological analysis was consistent with hemangioma associated with representative material representative of lung. Knowledge of such lesions becomes important as it contributes to the limited reports in the literature on congenital skin neoplasms in cattle, especially in regard to their clinical and pathological presentation.
