LEISHMANIASIS IN LABIAL MUCOSA: CASE REPORT

Abstract

Leishmaniasis is a serious problem of public health in Brazil and in the world. Caused by protozoa, it occurs more frequently in cutaneous form. Rarely, when it affects the oral mucosa, the disease is destructive or ulcerous-vegetative and granulomatous. This study reports the case of a 34-year-old patient with an ulcerated lesion with significant adjacent edema throughout the lower lip measuring about 3 cm with an asymptomatic evolution of 3 months, defined limits, rounded shape, reddish and yellowish color, and normal consistency. An incisional biopsy of the lesion was performed, and the material was sent for histopathologic and immunohistochemical analysis; which showed a lesion exhibiting lymphoid, hystiocytic and plasma cell infiltration, occupying the entire mucosal chorion, containing numerous structures with leishmania characteristics. The final diagnosis was mucocutaneous leishmaniasis. The patient underwent clinical and medical treatment with dermatologist, showing no signs of recurrence after 1 year.
