Plasma-cell gingivitis. Report of a case.

A well-documented case of plasma-cell gingivitis is presented. When viewed in a total perspective, the clinical examination, history of usage of a popular mint , laboratory data and histologic examination provide support for this diagnosis. This patient did not exhibit any evidence of glossitis or cheilitis as is often reported in the literature; however, a positive history to psoriasis was noted. The occurrence of plasma-cell gingivitis in a patient with documented psoriasis provides some interesting speculation regarding the etiologic picture of this condition.
