RESUMO
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.

An adult male mallard duck (Anas platyrhynchos) of unknown age was presented for acute intermittent respiratory distress that resolved when at rest. The duck had no history or evidence of trauma and had never been intubated. Radiographic imaging revealed a 1-cm tracheal defect at the level of the sixth vertebra. Surgical correction of the defect was pursued, during which a complete transverse tracheal rupture of unknown origin was identified. The separated tracheal sections were successfully anastomosed without resection of any tracheal rings. Tracheoscopy performed 2 months after the surgical procedure revealed healthy mucosa at the anastomosis site with a slight narrowing of the tracheal lumen.
