Dermoscopy of paederus dermatitis: Evolving patterns in a tropical irritant dermatosis

Paederus dermatitis occurs due to contact with the vesicant rather than the bite. It can present as erythematous papules, plaques, vesicles, bulla and crusting. Its diagnosis dermatitis can be quite challenging, especially in cases where the patient does not recall any history of contact with the beetle, which is often the case. Biopsy, being an invasive diagnostic technique, is typically avoided. There is a paucity of studies describing the dermoscopic characteristics of dermatitis. This case series elucidates the dermoscopic features associated with it.
