A Case of Primary Cutaneous Plasmacytoma , Observed for 10 years / 대한피부과학회지

ABSTRACT

A 28-year-old female devei,oped five rice-sized erythematous telaniectatic solid papules of her left side of cheek and numerous light brownish flat papules of her face two years before visiting our department of dermatology. Biopsy results of the erythematous papule vere dermal infiltration by well-differentiated, however, somewhat atypical and varying sized plasma cells involving epidermis, and the flat papule was that of verwca plana. Bone marrow aspirate was essentially normal. Primary cutaneous plasmacytoma is a rare disease. A significant proportion of patients with this ent on to develop systemic disease with a poor prognosis. Our patient was not treatead, bit only excised partially for biopsy. All skin lesions involuted two years later spontaneously and rema ns well until now six years later without recurring.
