LINFANGIOSSARCOMA EM CÃO: RELATO DE CASO

Abstract

Neoplasms are considered the leading cause of death in dogs and cats. Among the tumors that affect the lymphatic system can be mentioned benign lymphangioma and lymphangiosarcoma, a malignant tumor. The present work aims to describe a case of lymphangiosarcoma diagnosed in the scrotal region of a dog attended at the Veterinary Hospital of the Federal University of Paraíba, located in Areia-PB. The six-year-old mongrel male dog was undergoneto a clinical examination and performed several complementary tests such as hemogram, biochemistry, ultrasound and biopsy. In addition, therapeutic treatments were performed with Glycopan, Hemolitan and Enrofloxacin. In the hemogram microcytic anemia and hypochromic were found. In the biochemical examination the results obtained were considered normal and in the ultrasound, liver and prostate alterations were observed. Histological evaluation revealed a neoplastic mass with indistinct borders that infiltrates the dermis, formed by vascular channels filled by lymph with absence of red blood cells, confirming the diagnosis of lymphangiosarcoma. In this case, and in view of the confirmation of the diagnosis, taking into account the location of the tumor mass, the patient's condition and the results of the complementary tests, the most appropriate would be the surgical removal to increase the patient's survival. However, the animal cannot be submitted to this procedure and died after 35 days of diagnosis. It is concluded that neoplasms of lymphatic origin, although rare, have a high degree of malignancy and the prognosis is hardly good, and that in these cases the patient's survival is short. In view of this observation, the implantation of the biopsy as a complementary exam in the clinical routine is of great importance.
