Abstract
Mucosal plasmacytoses constitute a group of idiopathic inflammatory disorders, characterized by a dense infiltrate of plasma cells at the mucocutaneous junction without any recognizable dermatosis or neoplasm. We report an unusual clinical presentation of mucosal plasmacytosis presenting with hemorrhagic crusting of the lips, mimicking erythema multiforme.
