Cutaneous plasmacytoma (CP) is a localized collection of monoclonal plasma cells in the skin. The disease is divided into primary cutaneous plasmacytoma and secondary cutaneous plasmacytoma groups. Secondary cutaneous plasmacytoma, which is so rare as to occur in only 2% of myeloma cases, usually represents terminal expression of the primary diseases and is associated with increased tumor burden. CP can occur at any site of the skin, but we could find only 1 case in English literature related to scalp metastasis alone. Also serum and urine electrophoresis, tissue immunohistochemistry for IgD are not usually conducted in the laboratory. IgDlambda subtype seems to be another value to report. We report a case of secondary cutaneous plasmacytoma, IgDlambda type which developed on the scalp alone of a 41-year-old woman, with a review of related literatures.
