Co-Occurrence of Plasma Cell Orificial Mucositis and Plasmoacanthoma

Abstract

Plasma cell orificial mucositis is a relatively rare condition which may occur on mucous membranes. Plasmoacanthoma is a verrucous tumor with plasmacytic infiltration and has been described as a separate disease entity. Such a tumor is supposed to occur without lesions which could be compatible with plasma cell orificial mucositis. The present case report documents the coexistence of both conditions in one single patient. This observation suggests that both conditions are part of one single disease entity.
