title: Plasmacytoma of the cricoid cartilage with airway mass effect.
abstract: Although multiple myeloma is a common plasma cell dyscrasia, the deposition and organization of these malignant cells in the cricoid cartilage is rare. We report a case of plasmacytoma of the cricoid cartilage and secondary airway obstruction. This important report emphasizes the potential difficulty in diagnosing this condition, consequences of advanced disease, and the importance of combining laryngofissure biopsy and detailed imaging modalities to confirm the diagnosis and guide treatment.
