Abstract

A 50-year-old woman presented with a 2-year history of facial lesions that were resistant to rosacea therapy. Evaluation of histology, immunohistochemistry, gene rearrangement study, bone-marrow biopsy specimen, and systemic workup revealed the findings of lymphoplasmacytoid lymphoma (immunocytoma) in both the skin lesions and bone marrow, and IgM kappa paraprotein. Lesions cleared after chemotherapy.
