A Case of Multiple Cutaneous Reticulohistiocytoma / 대한피부과학회지

ABSTRACT

Multiple cutaneous reticulohistiocytoma, a unique pattern in the spectrum of the reticulohistiocytoses, is a rare reactive granulomatous condition. We report a case of multiple cutaneous reticulohistiocytoma in a 36-year-old female, who showed multiple, pruritic, yellow-reddish brown papules on her posterior neck and right upper back for 1 year. Histologically, numerous multinucleated giant cells with a ground glass appearance observed in the dermis. Immunohistochemical stains of CD68, Vimetin were positive. The lesions were subsided after applying topical steroid for 1 month.
