Abstract

Solitary cutaneous reticulohistiocytoma is characterized by a solitary reddish nodule or papule confined to the skin without evidence of arthritis or underlying systemic illness. We report a case of solitary cutaneous reticulohistiocytoma in a 41-year-old female, who presented with an asymptomatic, firm, dome-shaped nodule on the tragus of left ear. Histopathologically, numerous multinucleated giant cells with a ground glass appearance was shown in the dermis. Immunohistochemical stains of CD68 was positive. The lesion was completely excised and no evidence of recurrence was observed.
