title: Multiple myeloma involving the thyroid cartilage.
abstract: Extraosseous multiple myeloma involving the larynx is rare. We describe a patient with multiple myeloma and a plasmacytoma involving the thyroid cartilage. Ossification of the thyroid cartilage with formation of a marrow space could explain the occurrence of multiple myeloma in this unusual location.
