Diagnosis and treatment of tracheal basal cell carcinoma in a Maine coon and long-term outcome.

A 6 yr old castrated male Maine coon presented with a 2 wk history of progressive dyspnea. Thoracic radiographs revealed a 2 cm diameter intratracheal mass at the level of the fourth rib. The tracheal mass was marginally excised via a combination of resection and anastomosis. Infiltrative basal cell carcinoma (BCC) with nodular osseous metaplasia was diagnosed. The thoracic trachea was then irradiated postoperatively for definitive treatment. The cat remained asymptomatic following surgical excision and radiation therapy for 32 mo when this report was written. The purpose of this report is to describe the treatment and long-term outcome of a Maine coon diagnosed with, and treated for, tracheal BCC.
