A Case of Multiple Cutaneous Reticulohistiocytosis / 대한피부과학회지

ABSTRACT

Mutiple cutaneous reticulohistiocytosis represent a unique pattern in the spectrum of reticulohistiocytoses, and are characterized by multiple granulomas confined to the skin without evidence of arthritis or underlying systemic illness. We report a case of multiple cutaneous reticulohistiocytosis in a 31-year-old male, who presented with multiple, asymptomatic reddish-brown or skin-colored papules on the whole body. Histopathologically, there were numerous mononuclear and multinucleated histiocytes with a ground glass appearance in the dermis. The histiocytes were diastase-resistant, and periodic acid-Schiff reagent and CD 68 positive. The patient was treated with narrow band UVB for 1 month and slightly improved slightly.
