Tumors of the integumentary system are relatively common in companion birds. Dermal tumors in pet birds can be epithelial, mesenchymal, or vascular in origin. Basal cell carcinomas appear to be extremely rare in birds. An adult female blue-fronted Amazon parrot was examined because it exhibited bilateral cervical masses that extended from the base of the skull to the ingluvial region. The tumors were removed by surgical excision. Microscopic examination of the masses revealed neoplastic epithelial cells that extended to all borders of the sections; scattered vessels with neoplastic cells within their lumens were also found. The histopathologic diagnosis was basal cell carcinoma. Six weeks postoperatively, the masses recurred and the bird was euthanatized. This report suggests that basal cell carcinomas should be considered as a differential for avian dermal tumors. This neoplastic condition can be aggressive and has the potential to metastasize.
