Leishmaniasis visceral insospechada infiltrando un carcinoma epidermoide / Unsuspected Visceral Leishmaniasis Infiltrating a Squamous Cell Carcinoma

RESUMEN

En pacientes con SIDA y leishmaniasis visceral ha sido descrita la presencia de amastigotes de Leishmania en biopsias realizadas para estudiar diversas lesiones con las que no guardan aparente relación causal. Presentamos el caso de un varón de 40 años, VIH positivo severamente inmunodeprimido, en el que se observó incidentalmente la presencia del parásito al estudiar histológicamente un carcinoma epidermoide perianal. Dicho hallazgo permitió el diagnóstico y tratamiento de una leishmaniasis visceral insospechada. No hemos encontrado en la literatura ejemplos previos de esta asociación (AU)

ABSTRACT

Amastigotes of the genus Leishmania have been observed in biopsies of apparently unrelated lesions in patients with AIDS and visceral leishmaniasis. We describe the case of a 40-year-old man with human immunodeficiency virus infection and severe immunodepression in whom the presence of the parasite was detected as an incidental finding on histological study of a perianal squamous cell carcinoma. This finding led to the diagnosis and subsequent treatment of previously unsuspected visceral leishmaniasis. In a review of the literature we have found no previous examples of this association (AU)
