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

Bites 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.
