Abstract
Pruritus pigmentosa is a skin disease mainly characterized by pruritus, inflammatory rash and reticular and macular pigmentation. The disease more commonly affects young women and may persist for several years. In this article, we report a case of a 20-year-old female patient who presented with erythema and blisters on the neck and trunk with pruritus for 20 days. Dermatological examination revealed a reticular distribution of erythema on the chest and abdomen and some areas of erythema covered with crusts. Additionally, blisters and bullae with clear fluid and negative Nikolsky’s sign were noted. On the neck and back, erythema was also in a reticular distribution, and erythema secondary to erosion and/or crusts was present. In addition, histopathological analysis of the lesions showed hyperkeratosis and intraepidermal multilocular vesiculation and confirmed increased migration of inflammatory cells into the epidermis and infiltration of inflammatory cells, including lymphocytes, histiocytes and eosinophils, in the superficial dermis. The expression levels of IgG, IgM, IgA and C3 were all negative. This patient was diagnosed with prurigo pigmentosa, and the condition improved after treatment with minocycline.
