Plasma Cell Gingivitis-A Case Report

Plasma cell gingivitis (PCG) is a rare condition of the gingiva, characterized by infi ltration of plasma cells. Being a rare benign condition of the gingiva, PCG is characterized with erythematous and edematous gingivitis. The biologic phenomenon of the hypersensitive reaction appears to be chief etiology behind this occasionally presenting clinical entity. Plasma cell gingivitis has a close resemblance to discoid lupus, lichen planus, cicatricial pemphigoid or leukemia, and HIV gingivitis. It is known to present as a hypersensitive response to allergen, but sometimes it could present as a clinical entity with unknown etiology.

This paper reports a 60 year old female patient with the complaint of bleeding and swelling of gingiva since 2 months. On detailed history, patient was first diagnosed as drug induced gingival enlargement and based on histopathological findings, a diagnosis of plasma cell gingivitis was made.
