Two Cases of Vesiculopapular Prurigo Pigmentosa / 대한피부과학회지

ABSTRACT

Prurigo pigmentosa is a rare inflammatory disease of the skin characterized by the unexpected onset of diffuse erythematous papules and macules on the chest, neck, and back, that usually resolves leaving reticular hyperpigmentation behind. Rarely, vesicular or bullous forms have been reported. We present two cases of vesiculopapular prurigo pigmentosa in two women. Two 20-year-old women presented with multiple, pruritic, erythematous vesicles and papules of various sizes on their backs for 4 months and 3 weeks, respectively. One remembered having a similar vesicular eruption 2 years ago. Histological study and clinical findings showed a vesiculopapular prurigo pigmentosa. Treatment with doxycycline 200 mg/day and topical steroid lotion showed good responses. The lesions resolved after leaving a light brown reticulated hyperpigmentation behind. Herein, we report two cases of vesiculopapular prurigo pigmentosa successfully treated with doxycycline and topical steroid lotion.
