Abstract	Mastocitomas sao as neoplasias de pele mais comuns nos caes. O objetivo do presente estudo foi a analise histoquimica e histopatologica dos mastocitomas. Foi levantada a incidencia dos mastocitomas de 1998 a 2005 no Hospital Veterinario do UNIPINHAL. Aleatoriamente, foram selecionadas amostras dos 3 graus cutâneos para realizacao de metodos histoquimicos: hematoxilina/eosina (HE), azul de toluidina pH 4,0 (AT), Xylidine Ponceau pH 2,5 (XP) e Azul de Alcian pH 2,5 (AA). Foram identificados 103 animais com diagnostico de mastocitoma. Com a HE foram observadas poucas informacoes a respeito do tumor. O AT mostrou, no grau I, uma forte basofilia metacromatica nas celulas tumorais. Com grau II, foram detectadas celulas fortemente metacromaticas e celulas com basofilia moderada. Com grau III foram encontradas celulas em intensa degranulacao, com forte reatividade do estroma. O AA mostrou dados semelhantes aos registrados com AT. O XP mostrou celulas acidofilas nas amostras de mastocitoma grau I. Maior quantidade de celulas acidofilas foi achada em grau II. Com grau III foram identificadas celulas altamente acidofilas invadindo um estroma fortemente acidofilo. E possivel concluir que o metodo mais utilizado rotineiramente em histopatologia nao cora os grânulos dos mastocitos e as tecnicas que assim o fazem, nao evidenciam os limites celulares adequadamente.
