Mucosal leishmaniasis caused by Leishmania tropica in Saudi Arabia.

Mucocutaneous leishmaniasis (MCL.) which is called Espundia, and Uta is confined to South and Central America. In this form of leishmaniasis, the reticulo-endothelial system of the mucous membrane of the mouth, nose and throat is parasitized. It causes chronic ulceration of the mucous membranes with destruction of the bone and cartilage of the nose and mouth. In this study, two cases of mucosal leishmaniasis were recorded in two boys. In one patient, a primary lesion was identified on the patient's neck. In the second patient, no lesion or scar of old lesion or even history of leishmaniasis was reported. The causative agent was typed biochemically and proved to be Leishmania tropica.
