Lesions of Cutaneous Leishmaniasis Elicited after Local Trauma: A Case Report

Abstract

In Brazil there is an average of 30,000 cases of Cutaneous Leishmaniasis reported annually, and around the world it happens for about each 20 seconds. Although there are still opportunities to contribute with studies about this disease; supporting the medical community, especially dermatologists, mainly because of the necessity of knowing that a relatively simple procedure can result such a relevant trauma. Female patients presented erythematous plaque in the limb. Lesion appeared days after laser sessions for hair removal. Biopsy showed amastigotes forms and positive culture. After unsuccessful treatment it was managed with N-methyl glucamine 20 mgSbV/kg/day, during 20 days, there was significant improvement of the clinical picture. This study aims to present a case report of Cutaneous Leishmaniasis initiated after local trauma. Literature reports describe primary or secondary lesions of Cutaneous Leishmaniasis elicited after a local trauma. The mechanism used in order to explain these events was the migration of infected macrophages induced by cytokines. Similar events have also been reported as part of the locus minoris resistentiae concept that comprises situations in which microorganisms have a tendency to settle at places of weakened resistance. Considering that Leishmaniasis lesions are usually developed in promastigote forms are inoculated by the Phlebotominae, in this case it was noted that the infection has been favored by the local trauma.
