Plasma-cell gingivitis (PCG) is a rare, non-symptomatic lesion found in the attached gingiva. In the county of Södermanland 14 cases of PCG were identified during the last 13 years. Clinically, the PCG is a sharply demarcated red area within the attached gingiva. Abundant plasma cells are found in the connective tissue beneath a thin epithelium. Lesions with similar clinical appearance were also found in the genital mucosa of five of the patients with a PCG. An extensive bacterial plaque 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.
浆细胞性龈炎（PCG）是一种罕见的、无症状的病变，见于附着龈。在南曼兰郡，过去13年中确诊了14例PCG。临床上，PCG是附着龈内一个边界清晰的红色区域。在薄上皮下方的结缔组织中发现大量浆细胞。在5例PCG患者的生殖器黏膜中也发现了具有相似临床表现的病变。在患区的牙龈和牙齿上经常发现大量菌斑。尽管改善口腔或生殖器卫生并不能治愈病变，但对菌斑的过敏反应可能是病因。
