Plasma cell gingivitis: A perplexing and rare clinical entity

Abstract

Plasma cell gingivitis (PCG) is a diagnostic dilemma for clinicians. It is also referred to as atypical gingivostomatitis, idiopathic gingivostomatitis, allergic gingivostomatitis, and plasma cell gingivostomatitis which are characterized by bright fiery red gingiva with spontaneous bleeding on slight provocation. It is often confused with inflammatory gingival enlargement, erythematosus lichen planus, and other lesions. One such rare and benign entity is discussed in this article and managed after thorough clinical, radiological, histopathology, immunohistochemistry analysis.
