FIRST RECORD OF A CASE OF CUTANEOUS LOXOSCELISM CAUSED BY VIOLIN SPIDER (Loxosceles yucatana) BITE IN YUCATAN, MEXICO

Abstract

Loxoscelism occurs when the dermonecrotic venom produced by spiders of the genus Loxosceles, known as “violin spiders,” enters a person’s organism through their bite. In Mexico there is an underreporting of loxoscelism cases due to the absence of laboratory tests for its diagnosis and the complexity of the clinical picture. The aim of this paper is to describe a case of cutaneous loxoscelism caused by the bite of Loxosceles yucatana in a resident of Yucatan, Mexico. Cutaneous loxoscelism is the most frequent and less severe type. This case was diagnosed by means of the symptomatology registered in the medical records, the initial lesion, and the identification of L. yucatana spiders. This study represents the first description of a case of cutaneous loxoscelism with favorable outcome in Yucatan.
