Successive therapy of squamous cell carcinoma in African grey parrot

摘要

Epithelial tumors in birds originate in the surface epithelium, follicular epithelium or the uropygial glands. Squamous cell carcinomas (SCC) are often ulcerated and hemorrhagic, as well as infiltrative. SCC was diagnosed in pet birds (4, 8, 11, 13, 20, 21) as well as in wild birds (12). This type of neoplasia may occur anywhere on the body, being most prevalent at mucocutaneous junctions of the head on the distal wing and on the phalanges (4, 12, 13, 20, 21). Metastasis is not common, but occurs, particularly in chronic cases (16). Squamous cell carcinoma frequently appears grossly as a delayed or non-healing cutaneous infection, and diagnosis is therefore often delayed (11).
