Laryngeal plasma cell tumors are extremely rare and can be classified into three categories according to their primary site. 1. Plasma cell leukemia, 2. Intramedullary plasmacytoma, 3. Extramedullary plasmacytoma. The plasmacytoma of the larynx is mostly of the latter type, but it may also be the intramedullary plasmacytoma or plasma cell leukemia metastasis in soft tissue. Most of the laryngeal plasma cell tumors are benign and others have classified them as semi-malignant. Clinical manifestations: Laryngeal plasma cell tumors are more limited, a little can be infiltrated into the surrounding tissue and their lymph nodes. Slow growth, can be single, but also multiple, tumor blood vessels rich, the surface is red. According to the size and location of the tumor, the symptoms are different, and the symptoms of the epiglottis are not obvious.
