Plasma Cell Gingivitis: Clinical and Pathological Case Report.

Plasma cell gingivitis (PCG) is a rare benign condition usually found on marginal and attached gingiva. This case details a generalized PCG, to include the management of the patient and clinicopathologic characteristics of the disorder. The patient, a 24-year-old African American female, was referred to the periodontics clinic for severe generalized gingival erythema and edema. Past medical history review was remarkable for sickle cell anemia and systemic lupus erythematosus. The patient was initially prescribed dexamethasone oral rinse (0.5 mg/5 ml) pending biopsy and medical consult for potential causes of any hypersensitivity reaction. The patient also was instructed to discontinue her current type of oral mouthrinse and dentifrice. Biopsy results confirmed a diagnosis of PCG. Resolution of signs and symptoms started 1 month later, and approximately 2 years after initial diagnosis the patient was clinically stable. This report describes the management of a diffuse plasma cell gingivitis and reviews pertinent literature on the lesion. The etiology of PCG, although unclear, may be attributable to a hypersensitivity reaction. PCG may mimic other pathological entities, which underscores the importance of microscopic examination in establishing a definitive diagnosis before treatment initiation.
