Abstract

A 13-year-old castrated male Maltese dog was presented to a local animal hospital with an oral hemorrhage. An intraoral examination revealed an irregular proliferated lobular mass at the right side of the maxillary gingiva and hard palate. A surgically excised mass was requested for a histopathology examination. Histopathologically, the neoplastic foci were composed of biphasic morphologic patterns, such as primitive mesenchymal tissue and mature or immature cartilage tissue. Immunohistochemically, most of the neoplastic cells forming cartilaginous islands tested positive for S-100; the surrounding mesenchymal cells tested positive for vimentin. This paper describes a rare case of mesenchymal chondrosarcoma in the maxillary gingiva of a Maltese dog.
