A Case of Extramedullary Plasmacytoma of the Larynx / 대한이비인후과학회지

ABSTRACT

Extramedullary plasmacytoma is a rare soft tissue malignancy composed of plasma cells. This tumor may be primary or secondary to the generalized multiple myeloma. The great majority of extramedullary plasmacytoma occurs in the head and neck region, mainly in the upper respiratory tract and oral cavity. The most frequently involved sites are the nasal cavity, paranasal sinus, and nasopharynx, in the decreasing order. However extramedullary plasmacytoma of the larynx is rare. Laryngeal plasmacytomas accounts for between 6 to 18% of all extramedullary plasmacytomas. We report, with a review of literature, a case of extramedullary plasmacytoma of the larynx in a 41 year-old female patient.
