Abstract:
Molluscum contagiosum is a common pediatric viral skin infection characterized by small, flesh-colored, umbilicated papules on the skin. Molluscum contagiosum lesions are typically benign and self-resolve, but they may trigger a surrounding eczematous dermatitis that may mimic other infections or an atopic dermatitis flare. We report a case of an 8-year-old boy with eczematous molluscum contagiosum whose eruption masqueraded as herpes simplex virus infection. The patient presented with a several week history of pruritic rash with bleeding and crusting, but careful examination revealed conventional umbilicated papules consistent with molluscum contagiosum. The dermatitis was managed with conservative skin care, low-potency corticosteroids, and topical antibiotics (for cracked skin/open sores). This case highlights the importance of recognizing molluscum dermatitis and distinguishing it from herpes simplex virus, atopic dermatitis flare, or bacterial infection to avoid unnecessary investigations or treatments.
