| Summary: | Prurigo pigmentosa is a rare inflammatory skin disease characterized by an unexpected onset of diffuse erythematous papules and macules usually on the chest, neck, and back. These generally resolve, leaving reticular hyperpigmentation. Rarely, vesicular or bullous forms have been reported. We present a case of exfoliative vesiculobullous prurigo pigmentosa in a 13-year-old boy. He presented with symmetrical eruption of papules and vesicles on his back, neck, and chest in the last 10 days, causing pruritis and prickling sensation. Within a few days, the bullous lesions and all affected areas of the skin showed exfoliation. Histological study and clinical findings indicated the condition to be vesiculobullous prurigo pigmentosa with exfoliation. Treatment with doxycycline 200 mg/day and topical tacrolimus ointment showed a good response. The lesions resolved, leaving a light-brown reticulated hyperpigmentation. In conclusion, this was a case of exfoliative vesiculobullous prurigo pigmentosa in an adolescent man successfully treated with doxycycline and topical tacrolimus as an effective and safe treatment option.
