Abstract
|
|
|
Prurigo pigmentosa is a chronic pruritic inflammatory dermatosis characterized by erythematous papules in a reticulated pattern that resolve leaving a reticulated, mottled hyperpigmentation and rapidly response to dapsone therapy. Most cases that
have
been reported are from Japan.
We report two cases of prurigo pigmentosa in a 21-year-old female and a 23-year-old female. Histopathologic findings of erythematous papules showed exocytosis, spongiosis, liquefaction degeneration of basal cell layer and perivascular
lymphohistiocytic
infiltration on the upper dermis. We treated them with dapsone, 100mg daily, which resulted in a remarkable regression of the erythematous papules and improvement of pruritus. (Kor J Dermatol 1995;33(5) : 945~949)
