A Case of Cutaneous Leishmaniasis guyanensis Mimicking Otitis Externa

Mil Med. 2017 Jul;182(7):e1969-e1972. doi: 10.7205/MILMED-D-17-00054.

Abstract

Cutaneous leishmaniasis typically presents as a painless papule progressing to an ulcer or plaque. In this case study of the ear, the disease manifested as a small painful bump progressing into redness and swelling about the ear with purulent drainage. After multiple oral/intravenous antipseudomonal, antistaphylococcal, and antifungal treatments, there was no improvement. The skin progressed to an erythematous plaque and hemorrhagic ulcer; punch biopsy and speciation revealed Leishmaniasis guyanensis. The patient was switched to a seven-dose course of intravenous L-amphotericin B (visceral leishmaniasis protocol). Within 21 days, pain and edema resolved and the ulcers healed. Three-month follow-up demonstrated no recurrence. Further studies are needed to evaluate the use of L-amphotericin B in Leishmaniasis guyanensis.
