Adenocarcinoma apócrino misto metastático em cão da raça fila brasileiro: relato de caso

Abstract

Mixed apocrine adenocarcinoma is a rare malignant neoplasm in dogs, characterized by its high metastatic potential to several organs. This neoplasm usually manifests predominantly in the head and neck region, as well as in the trunk and limbs, presenting as multilobulated nodules. In its malignant form, it tends to recur locally and metastasize to regional lymph nodes and the lungs. This study aims to report a case of mixed apocrine adenocarcinoma in a five-year-old female dog of the Fila Brasileiro breed. The animal was treated at the Veterinary Hospital of the Federal University of Paraíba- UFPB, where the diagnosis and classification were performed through detailed clinical, laboratory and histopathological evaluation. Based on these findings, it was possible to reach the diagnosis of mixed apocrine adenocarcinoma, with cervical involvement and metastasis in the spleen.
