Various clinical presentations in the upper airway have been reported ranging from erythematous mucosa to fungating masses. Histologic features include mucosal epithelial hyperplasia or psoriasiform changes with a dense submucosal infiltrate of polytypic plasma cells. Molecular studies for immunoglobulin gene rearrangement should be performed in all cases of MMP to rule out clonal neoplastic expansion of plasma cells. We present a case of MMP with over 15 years of clinical follow-up, emphasizing the relatively benign clinical course of this disorder.en-US© 2019 The Author(s). Published by Elsevier Ltd.
