Abstract: A 16-year-old male Congo African grey parrot (Psittacus erithacus) was presented with an ulcerated wing mass that was excised and diagnosed on histopathology as squamous cell carcinoma (SCC). A second surgery was performed to completely excise the tumor margins, resulting in over 5 years of remission for the neoplasm. However, over the next 6 years the patient developed SCC in 3 new locations on the body, as well as 2 squamous papillomas. The 2 papillomas were surgically excised and did not recur. Due to their size and location, none of the 3 new SCCs were amenable to complete excision. Instead, the 3 SCCs were managed with a series of treatments with intralesional carboplatin in poloxamer 407 and carbon dioxide surgical laser debridements. This treatment regimen has resulted in long-term (52 months, 30 months, and 17 months) resolution for all 3 of the SCCs. The overall survival time for the patient, from the initial diagnosis to the time of this report, is over 2900 days. While being treated for the 3 SCCs, the African grey parrot had no overt signs of complications or adverse side effects.
