A Case of Multiple Myeloma Diagnosed from Tongue Amyloidosis

Abstract

Amyloid deposition may occur in the oral cavity as a local symptom of systemic amyloidosis.
We report a case of multiple myeloma with tongue amyloidosis. The patient was a 70-year-old female complained of swelling and pain of tongue. An ulcer in the tongue margin was observed and the biopsy specimen showed amyloid deposition. After systemic examinations, the patient was diagnosed as having multiple myeloma and so the lesion was a local systemic amyloidosis due to multiple myeloma.
