O mastocitoma é um tumor maligno comum nos cães, podendo acometer a pele ou tecido subcutâneo, sendo este último tipo pouco abordado na literatura. O objetivo deste trabalho foi relatar o tratamento de um cão com mastocitoma subcutâneo desde o diagnóstico até o tratamento convencional em associação ao Viscum álbum.
O exame histopatológico foi utilizado para diagnóstico e para avaliação dos linfonodos sentinelas. A cirurgia foi necessária para ampliação de margens e remoção dos linfonodos alterados. A eletroquimioterapia foi feita com bleomicina e a quimioterapia foi feita com vimblastina. O Viscum álbum foi instituído com o intuito de diminuir os efeitos maléficos do câncer e da quimioterapia. O animal se recupera bem, sem sinais de recidiva ou metástase.
