Local cutaneous arachnidism: a report of three cases and their management

SummaryBites from Loxosceles spiders can cause few symptoms to gangrenous skin necrosis or even death. To date, the treatment of the violin spider bite is largely unsatisfactory. Although no specific therapy exists, it has been suggested that heparin, steroids, dapsone, experimental antivenin and/or surgical excision may be beneficial.Three rare cases of suspected spider bite and their surgical treatment are reported. On the basis of geographical area, anamnesis and clinical symptoms, we suppose Loxoceles rufescens responsible for these bites.
