chiclero ulcer /chikler″ō/ [Mex, tzictli, chicle; L, ulcus] , a kind of American leishmaniasis caused by Leishmania mexicana. It is endemic among the workers in the Yucatan and Central America who harvest chicle from the forest. The disease is characterized by cutaneous ulcers on the head that usually heal spontaneously within 6 months, except for those on the pinna of the ear, which may last for years and cause scarring and deformities. See also American leishmaniasis, leishmaniasis.
