A Case of Plasmacytosis Successfully Treated with Corticosteroids

Abstract

Plasmacytosis is a chronic inflammatory disease that occurs in a body opening, such as the oral cavity or vulva, and is accompanied by mucosal redness, erosion, and edematous changes. Histopathological examination has revealed epithelial thinning and plasma cells. Plasmacytosis is a relatively rare disease with infiltration. Herein, we report a case of open-cell plasmacytosis that was successfully treated with corticosteroids despite difficulties in diagnosis and treatment.
