Isolated lingual leishmaniasis.

Cutaneous leishmaniasis is endemic in Fars Province, southern Iran. However, mucosal leishmaniasis is extremely uncommon. Herein, we report a patient with isolated lingual leishmaniasis in an immunocompetent 40-year-old man. The lesion was totally excised. The patient was cured completely and is doing well after four years of follow-up, with no medical treatment.
