Esophageal Squamous Cell Carcinoma in a Nanday Conure (Aratinga nenday)

A 17-year-old Nanday conure (Aratinga nenday) was presented for weakness, occasional dyspnea, and ruffling. The reported clinical signs were intermittent respiratory distress and rare mucus production from the mouth in the past two weeks. A radiopaque mass of 1-centimeter was detected just cranially to the heart during the radiographic examination. Esophageal and clavicular air sac endoscopy confirmed a severe esophageal dilation causing a ventral displacement of the syrinx. Five months after initial presentation the bird died.
Necropsy with histopathology were performed. Histopathological findings were compatible with a distal esophageal squamous cell carcinoma.
According to the authors, this report is the first distal esophageal squamous cell carcinoma reported in a Nanday conure. Moreover, the use of clavicular air sac endoscopy in order to obtain biopsy sample, reveled a good tolerability by the patient, with rapid recovery times and absence of adverse effects.
