title: Squamous-cell carcinoma of the pharyngeal cavity in a Jersey black giant rooster.
abstract: Squamous-cell carcinoma of the pharyngeal cavity was diagnosed in a 3-year-old Jersey black giant male chicken. Grossly, the carcinoma was round with irregular edges, yellow-tan, cauliflower-like with a crusty surface, and attached to the roof and sides of the pharyngeal cavity. Histologically, the surface of the mass was covered by a dense mat of necrotic mucosa and inflammatory cells. A broad front of neoplastic cords consisting of squamous epithelial cells extended into the lamina propria. There was no evidence of vascular invasion or metastasis.
