title: Extramedullary plasmacytoma of the larynx: a case report from Japan.
abstract: Laryngeal plasmacytoma is rare in Japan; to the best of our knowledge, only 8 other cases have been previously reported. We report a new case of extramedullary plasmacytoma of the larynx in a 76-year-old Japanese woman. Immunohistochemical investigation revealed that her disease had not progressed to multiple myeloma. The patient declined radiotherapy, and her condition remained stable at the 6-month follow-up.
