Cutaneous Loxoscelism Associated Exanthem Mimicking Acute Generalized Exanthematous Pustulosis

Abstract

A 33‑year‑old female presented with a generalized sudden onset rash that appeared a day after a spider bite on her left upper thigh. It was associated with burning sensation and pain over the site of bite. Examination revealed discrete and coalescent erythematous maculopapular lesions with pinpoint to pin‑head‑sized pustules and scaling predominantly involving the axillae, cubital and politeal fossae, thighs, and proximal legs bilaterally. There was no mucosal involvement or lymphadenopathy.
