Liver is the largest gland in the body, which has a great diversity of functions. It is parenchymal and glandular. Chicken livers may undergo several alterations, including bacterial, parasitic, neoplastic, among other. Chicken meat and its byproducts are sources of diseases transmitted to humans. That is why in order to ensure the public health, meat and viscera are considered unfit for consumption. In this research were examined, macroscopically and microscopically, 100 chicken livers, with an average age of 33 days, weight 1,3 to 1,6 kg, that led the loss of the entire carcass, in line B of a slaughterhouse inspection, located in the region of the Triângulo Mineiro. Macroscopically, it was possible to observe a coherence with the data describe by the literature such as liver with increased volume, reddish, greenish, yellowish, whitish spots and friable. Microscopically, the lesions found in most livers were infiltrated with heterophile, followed by neoplastic cells clustered. Thus it was possible to conclude that the etiologic diagnosis in macro and microscopically alterations is compatible with colibacillosis (80%) and leucosis myeloid (20%) respectively.

ResumoO feocromocitoma é o tumor mais frequente da medular da adrenal, originado de células cromafins denominadas de feocromócitos, que ocorrem não só na medular da adrenal como também nos paragânglios do sistema nervoso simpático. É uma neoplasia rara nos cães, responsável por aproximadamente 0,01 a 0,13% dos tumores caninos, sendo ainda mais raro em gatos. Os exames laboratoriais, na suspeita de feocromocitoma, procuram comprovar a hipersecreção de catecolaminas e deve proceder a propedêutica por imagens.A pesquisa deve ser iniciada pelas dosagens basais de catecolaminas e seus metabólitos na urina e no sangue.
