PLASMA-CELL GINGIVITIS IN CHILDREN AND ADULTS - A CLINICAL AND HISTOLOGICAL DESCRIPTION

Plasma-cell gingivitis (PCG) is a rare, non-symtomatic lesion found in the attached gingiva. In the county of Sodermanland 14 cases of PCG w ere identified during the last 13 years. Clinically, the PCG is a shar ply demarcated red area within the attached gingiva. Abundant plasma c ells are found in the connective tissue beneath a thin epithelium. Les ions with similar clinical appearance were also found in the genital m ucosa of five of the patients with a PCG. An extensive bacterial plaqu e was frequently found on the gingiva and teeth in the affected areas. Although an improved oral or genital hygiene did not heal the lesions , an allergic reaction to the bacterial plaque may be the cause.
