Erythroderma and Skin Desquamation in Paederus Dermatitis

Exfoliative erythroderma is rare but serious condition, which requires close supervision. We report a rare case of 28-year-old man with kissing lesions of Paederus dermatitis at his right side of neck. The rash caused by Paederus beetle was improved after treatments. However, the patient developed generalized erythema with desquamation and scaling. The patient was successfully treated topically with moisturizing liquid soap and topical moisturizer with emollients and humectants, and triamcinolone lotion was applied on the bright red lesion. The patient was also treated with oral replacement solution and tropical azelaic cream was applied on the hyperpigmented kissing lesion. This case report shows the importance of a diagnostic practice with follow-up examination.
