ABSTRACT
Prurigo pigmentosa is a papular pruriginous eruption of unknown origin that leaves a reticulated, mottled hyperpigmentation. The condition is rare in the Western world, but many cases have been described in Japan. In Korea, six cases of prurigo pigmentosa have been reported, but follow-up of clinical course from the onset to the late stage was not performed. We report a case of prurigo pigmentosa, followed-up for 4 years, in a 21-year-old male. Four years ago, coalescent erythematous papules and reticular pigmentation on the chest, neck and the upper arms were observed. Histopathologic findings of erythematous papule showed moderate acanthosis, a few necrotic keratinocytes and focal hydropic degeneration in the basal cell layer in association with melanophages and perivascular lymphocytic infiltration of the upper dermis. The skin biopsy from the latest hyperpigmented lesion showed only melanophages and mild perivascular lymphocytic infiltrates in the upper dermis. During the 4 years of follow-up period, we noticed that reticulated hyperpigmentation is localized to the almost same sites with the previous papular lesion.
