Ca. Hedin et al., PLASMA-CELL GINGIVITIS IN CHILDREN AND ADULTS - A CLINICAL AND HISTOLOGICAL DESCRIPTION, Swedish dental journal, 18(4), 1994, pp. 117-124
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.
