SQUAMOUS CELL CARCINOMA OF THE ROSTRAL MAXILLA IN AN ADULT CAPTIVE WHITESPOTTED BAMBOO SHARK (CHILOSCYLLIUM PLAGIOSUM).

An approximately 10-yr-old adult female whitespotted bamboo shark (Chiloscyllium plagiosum) presented with a smooth, white, irregular, ulcerated, and expansile lesion on the left lateral aspect of the maxillary rostrum. The lesion had short periods of abrupt and rapid proliferation and then remained static for several months. Cytology and culture were nonspecific and did not reveal any discernible etiologic agents or cellular atypia.
