Cutaneous leishmaniosis due to Leishmania mexicana in a cat treated with cryotherapy.

We report the novel use of cryosurgery to treat cutaneous feline leishmaniosis (FeL) in a domestic cat from mid-western Venezuela. Amastigotes, evident by microscopy in aspirates from the nodular, erythematous nose lesions, were identified as Leishmania mexicana by cytochrome b gene sequence analysis. Lesions resolved completely without relapse after 14 months.
