Abstract
Extramedullary plasmacytoma (EMP) is a plasma cell neoplasm of soft tissue without bone marrow involvement or other systemic characteristics of multiple myeloma. Approximately 80%–90% of EMPs involve the head and neck region, especially in the nasal cavity, paranasal sinuses, tonsillar fossa, and oral cavity. An EMP of the larynx is extremely rare and is a locally destructive lesion without systemic spread. Clinical features vary depending on the tumor location. A diagnosis is established by histopathology, immunohistochemistry, and a systemic survey to exclude systemic plasma cell proliferative diseases. Extramedullary plasmacytomas are highly radiosensitive and radiotherapy is therefore used as a treatment. In this study, we report on a rare case of EMP of the larynx evaluated with computed tomography and present histopathologic findings for a 74-year-old female patient.
