Probable cutaneous loxoscelism with mild systemic symptoms: A case report from Spain.

Abstract We present a case from Valencia, Spain, of a 25-year-old woman who presented with a painful erythematous skin lesion, initially diagnosed as cellulitis. The lesion was unresponsive to antibiotic treatments and progressed into a hemorrhagic blister with necrotic ulcer formation. Posterior collection of a spider from the patient's home and expert identification of the spider as Loxosceles rufescens was achieved, establishing the diagnosis of probable cutaneous loxoscelism. Symptomatic treatment, general wound care and ultimately surgery, resulted in complete recovery with minor residual scarring. This case illustrates some of the difficulties encountered in the diagnosis and treatment of loxoscelism and adds to the increasing reports of loxoscelism in the Mediterranean Basin. Highlights • We present a case of probable cutaneous loxoscelism from Valencia, Spain. • Reports of loxoscelism in Europe, especially the Mediterranean Basin, have been increasing. • Diagnosis was based on compatible history and symptoms, accompanied by spider collection and expert identification. • In our case, management was based on general wound care and surgery. • Complete recovery with only minor residual scarring was achieved.
