Localized cutaneous leishmaniasis (LCL) of the ear is characterized by a single ulceration without mucosal or lymphatic involvement.1 When progressing on the ear, LCL often involves cartilagenous structures, spontaneously lasts for months to years, and may cause severe mutilation.2 This case report suggests that Pseudomonas aeruginosa secondary infection of the cartilaginous structures may be a co-factor of mutilation.
