A Case of Primary Cutaneous Plasmacytoma Improved by Intralesional Steroid Injection / 대한피부과학회지

ABSTRACT

Primary cutaneous plasmacytoma (PCP) is a very rare cutaneous B-cell lymphoma that arises primarily in the skin. A few cases of PCP have been reported previously. PCPs are histologically similar to cutaneous B-cell lymphoma and are characterized by dense monoclonal plasma cell infiltration in the dermis. PCP can manifest as a single lesion or as multiple lesions. A solitary lesion can be treated with surgical excision or local radiotherapy. We describe the case of a patient with primary cutaneous plasmacytoma that was treated with intralesional steroid injections.
