Dermal squamous cell carcinoma in young chickens.
In recent years, squamous cell carcinoma in the skin of young chickens has been found more frequently at slaughter. Two nationwide surveys were completed, which verified the neoplastic classification grossly and microscopically. The deep, ulcerative lesions were found in birds from all geographic locations in the country. The medical history of the flocks was inconclusive and no site of predilection was observed. Presently, the frequency averages 2 per 10,000 birds slaughtered. The casue of this neoplastic skin condition has not been determined.
