Hemangiossarcoma em trinca-ferro(Saltator Maximus)com metáse pulmonar - Relato de caso

Abstract

Hemangiosarcomas are characterized by a high tissue invasion capacity and frequent occurrence of metastasis. Information about hemangiosarcomas in birds is limited. The Saltator maximus is a bird belonging to the order Passeriformes, they can be found in the wild or as a pet in Brazil. This study aims to report a case of cutaneous hemangiosarcoma in a buff throated saltator (Saltator maximus) with pulmonary metastasis. Among pet birds, the diagnosis of skin cancer is more frequent. The occurrence of hemangiosarcomas in birds may be related to chronic inflammation by trauma and retrovirus. A three-year-old male S. maximus was referred to the Veterinary Hospital of the Universidade Federal da Paraíba with a pedunculated nodular mass in the pericloacal region, and a clinical, radiographic and blood test was performed. A surgical procedure was performed, but the patient died. The mass and carcass were sent for macroscopic, histological and immunohistochemical evaluation. Findings compatible with hemangiosarcoma were found on histology and immunohistochemistry. In passeriformes reports of this neoplasm are particularly scarce. This is the first report of a hemangiosarcoma in S. maximus, for confirmatory diagnosis using histopathology and immunohistochemistry.
