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.

Solitary cutaneous reticulohistiocytoma is a type of reticulohistiocytosis. The cytoplasm of tumo cells characteristically shows abundant eosinophilic "ground-glass" appearance. We report a case of this rare cutaneous tumor in a 54-year-old woman. It was present as a single nodule on the right index finger of the patient for seven years.
