Abstract:
An 8-year-old female adult reindeer (Rangifer tarandus tarandus) was referred to the Veterinary Hospital of Madrid for evaluation of a conjunctival mass on the left eye which had been present for about 2 months. A surgical excision was performed and biopsy material submitted for light microscopic evaluation which confirmed the diagnosis of conjuctival squamous cell carcinoma. Nuclear p53 immunolabeling was found in 52% of the neoplastic cells. Follow-up examination at 12 months postsurgery did not reveal recurrence of this neoplasm. Conjunctival squamous cell carcinoma has not been reported previously in reindeer and seems to have similar characteristics to the one existing in bovine species.
