Case report of malignant mammary neoplasia in Mexican gray wolf (Canis lupus baileyi)

Abstract

We report the presence, excision and diagnosis of malignant mammary neoplasia from a 14 years old female Mexican gray wolf (Canis lupus baileyi). Through auscultation we observed and palpated three neoplasia in the mammary gland. We also noted anorexia, lethargy in the animal with rigidity and lameness in the posterior end of the body. We surgically removed the tumors and took samples for histopathological studies which revealed a mixed mammary tumor composed of infiltrating ductal carcinoma with centers of mucinous, epidermoid and chondrosarcoma (chondrosarcoma carcinoma). © Medwell Journals, 2010.
