Spider bites of medical significance in the Mediterranean area: misdiagnosis, clinical features and management

Abstract: Despite the disrepute spiders have had for centuries, their bite is a rare occurrence. In the Mediterranean area, only two of the numerous known species are considered of medical significance: Latrodectus tredecimguttatus and Loxosceles rufescens. Spider bites have no pathognomonic signs or symptoms, therefore most diagnoses are presumptive; a spider bite can only be diagnosed when a spider (seen at the time of the bite) is collected and identified by an expert, since most physicians and patients are unable to… Show more

“…The clinical presentation reported for the patients was characterized by intense pain at the bite site, associated with local signs: oedema with visible skin punctures, possibly pruritus and paraesthesias in the bitten area. These signs correspond with those usually reported in the literature (Fusto et al, 2020; Varl et al, 2017). General signs (headache, hyperthermia) have been reported for 10%–20% of cases for which spider identification was uncertain (Vetter et al, 2006).…”

“…One bite out of five occurred in the Provence‐Alpes‐Côte d'Azur region, which corresponds to the distribution area of this spider. It can be found near or even inside houses, where it finds a suitable temperature all year round (Fusto et al, 2020; Nentwig et al, 2017). Although it is not a particularly aggressive spider, it can bite when it feels threatened or is accidentally pressed against the human skin, which can happen during the night when the patient turns over in their sheets or when they put on their clothes (Mullen & Vetter, 2019).…”

“…Among the few species of spiders considered of medical significance, whose bite may have severe complications, only two spider species can be found in the Mediterranean area: Latrodectus tredecimguttatus (known as Mediterranean black widow) and Loxosceles rufescens (known as violin spider), which is native to Europe but has been spread worldwide 4 . We showed the patient photos of the two spiders most likely responsible for the injury, and he recognized with sufficient certainty that it was a bite of a violin spider.…”
