FREQUÊNCIA DE NEOPLASIAS CUTÂNEAS EM EQUINOS: ESTUDO RETROSPECTIVO DO LABORATÓRIO DE PATOLOGIA VETERINÁRIA DA UNIVERSIDADE FEDERAL DO PARANÁ

O objetivo deste estudo foi determinar a prevalencia dos tumores cutâneos de equinos examinados pelo Laboratorio de Patologia Veterinaria (LABPV) da Universidade Federal do Parana (UFPR), Campus Curitiba. Foram pesquisados os protocolos de biopsia de pele destes animais, no periodo de 1984 a 2008. Os dados utilizados foram diagnostico morfologico, sexo, idade e raca. Das 201 amostras recebidas, 166 (82,6%) eram de tumores cutâneos, sendo 150 (74,6%) neoplasicos. A raca mais prevalente foi a Puro Sangue Ingles 112 animais (67,5%); seguida da Crioula 29 (17,5%); Quarto de Milha 15 (9,0%) e Mangalarga Marchador 7 (4,2%). Animais sem raca definida somaram 3 (1,8%) do total. A faixa etaria mais prevalente, em ordem decrescente, foi: a 1-5 anos com 108 equinos (65,1%); 6-14 anos 41 (24,7%); cavalos com 15 anos ou mais 13 (7,8%) e com menos um ano apenas 1 cavalo (0,6%). Com relacao ao sexo, 102 (61,5%) eram femeas, 61 (36,7%) eram machos e em casos o genero (1,8%) nao foi informado. As neoplasia cutâneas mais prevalentes foram: sarcoide com 111 casos (66,87%); carcinoma de celulas escamosas  12 (7,23%); papiloma 11 (6,63%) e outros tumores somaram 32 (19,87%). A raca Puro Sangue Ingles apresentou a maior prevalencia para sarcoide, carcinoma de celulas escamosas e papiloma; sendo 77/111 (69,4%); 7/12 (58,4%) e 8/11 (72,7%), respectivamente.
