title: Extramedullary plasmacytoma of the soft palate.
abstract: A 59-year-old white male presented with symptoms of an upper respiratory infection and the sensation of nasal fullness or obstruction. There were no constitutional symptoms or history of previous oropharyngeal neoplasms. Examination revealed a fleshy tan-pink 2 cm. x 1 cm. pedunculated lesion at the base of the uvula posteriorly, extending into the posterior soft palate. Indirect laryngoscopy confirmed extension of the lesion base onto the posterior soft palate. There was no palpable cervical adenopathy. CT scan of the sinuses and neck revealed no abnormality except the soft tissue mass in the area of the uvula and soft palate. Excisional biopsy of the lesion revealed a plasmacytoma which produced a monoclonal lambda chain immunoglobulin. Hemoglobin was 17.2 g/d. Serum electrophoresis and immunophoresis, Bence-Jones protein, bone marrow, and bone scan were normal. Twenty-six months later, a 1.5 cm. pedunculated lesion was noted at the site of original tumor, which was demonstrated to be recurrent plasmacytoma on excisional biopsy. No other lesions were identified on direct laryngoscopy and skeletal survey was normal. Repeat laboratory studies were normal except for a slight hypergammaglobulinemia (total protein 6.4 g/d., albumin 51.5 percent, alpha 1 globulin 4.0 percent, alpha 2 globulin 11.4 percent, beta globulin 12.8 percent, and gamma globulin 20.2 percent). The patient refused further treatment and has had no further recurrences at one year.
