  • Title: Plasma Cell Gingivitis and Its Mimics.
    Author: Younis RH, Georgaki M, Nikitakis NG.
    Journal: Oral Maxillofac Surg Clin North Am; 2023 May; 35(2):261-270. PubMed ID: 36805902.
    Abstract:
    Plasma cell gingivitis (PCG) is an inflammatory condition that affects the gingival mucosa of the oral cavity. It is characterized by polyclonal dense plasma cell infiltrate in the connective tissue. Lesions do not respond to prophylactic treatment. Etiology is most likely hypersensitivity to certain antigens (eg, toothpastes, oral rinses, chewing gums, spices). Differential diagnosis of PCG includes reactive, granulomatous, and neoplastic lesions. The diagnostic workup is based on patient's history and the clinicopathologic correlation to rule out mimics of PCG. Dermatologic patch test may be indicated in chronic conditions to identify the allergen.
