Neurofibrosarcoma and leiomyosarcoma in slaughterhouse broilers.
Two uncommon neoplastic lesions--a neurofibrosarcoma and a leiomyosarcoma--were found in 7-week-old slaughterhouse chickens. Grossly, the neoplasms both appeared as locally extensive, nodular lesions that displaced the mesentery and abdominal viscera. Histologically, these tumors were anaplastic and invasive into the surrounding tissues.
