Leishmaniasis in the knee area

Leishmaniasis is a parasitic infection caused by species leishmaniae, which can produce two types of manifestations: visceral and cutaneous. In south America cutaneous leishmaniasis is more common than visceral leishmaniasis. A case of primary cutaneous leishmaniasis from Bolivia is presented for its rarity. The patient of our case showed an ulcerated lesion of the knee. Montenegro's intradermal test was positive. Giemsa-stained touch preparation of the skin biopsy revealed amastigotes inside macrophages, consistent with leishmaniasis. The patient was treated with meglumine antimoniate intramuscular (20 mg of Sb+/kg/day) three weeks, with complete cicatrization of the lesion
