title: Plasma-cell granuloma of the gingiva.
abstract: A case of plasma-cell granuloma of the attached gingiva has been presented. The lesion was pedunculated and, clinically, resembled a traumatic fibroma. The microscopic picture was that of plasma-cell granuloma. Serum electrophoresis and radiographs were normal. A diagnosis of plasma-cell granuloma confirms a benign lesion of the oral cavity which must not be confused with the plasmacytoma, a possible precursor to multiple myeloma. This case emphasized the need for biopsy of lesions in order to establish a diagnosis. Only by biopsy and histologic study can rare lesions be diagnosed and their incidence studied.
