Squamous cell carcinoma in goats of two farmers in the State of Pará is described. Prevalence, correlation with the pigmentation of the perineal area and macro and microscopic characteristics of the lesions were studied. The tumors on the perineum were of varied development degrees, diameters and forms. On one farm, in the county of Viseu, from a total of 347 goats, 20 presented the neoplasia (5.8%). On the second farm, in the county of Garrafão do Norte, three cases of squamous cell carcinoma in a herd of 400 goats (0.75 %) were observed. The tumor was only observed in animals in which the perineal area was despigmented. The high incidence of this tumor appears to be due, to lack of pigmentation at the períneo and the high and short tail of the goats, that exposes the area to intense of ultraviolet radiation in the tropics. |
