ABSTRACT
Leishmaniasis is a parasitic disease considered an endemic public health problem in developing countries, where it is a reportable disease. Isolated oral manifestation is rare, and its clinical manifestations are variable. In this paper we describe an unusual case of an immunocompetent patient, 57-year-old man with a painless reddish submucosal nodule located on the tongue dorsum. Microscopical analysis showed chronic inflammatory infiltrate with macrophages containing leishmania in cytoplasmic vacuoles. PCR assays confirmed the diagnosis and patient was treated with meglumine antimoniate for 30 days. Absence of the parasite was confirmed by PCR. Thirteen years after treatment, a scar fibrosis persisted on the tongue dorsum. The case reported reveals that leishmaniasis should be considered in the diagnosis of tongue nodules in immunocompetent patients.

O planejamento de programas de controle de zoonoses urbanas como a raiva baseia-se no conhecimento do tamanho e estrutura da populaçäo canina e felina. Assim, no período de 21 de junho a 30 de agosto de 1994, foram realizadas visitas, casa a casa, com a finalidade de avaliar, mediante a aplicaçäo de um questionário, o tamanho das populaçöes humana, canina e felina da zona urbana de Araçatuba. A relaçäo média cäo/homem observada foi de 2,8:10, ou seja, 2,8 vezes maior que a geralmente utilizada para o planejamento de campanhas de vacinaçäo anti-rábica, de um cäo para cada 10 habitantes
