Abstract
Amyloidosis is a lesion in which an amyloid substance deposits in various organs and tissues of the body.
Recently, we experienced a case of primary amyloidosis forming multiple nodules in the tongue. The patient was a 74-year-old male.
Multiple nodules, 5-10mm in diameter, were observed in the tongue and the lingual frenulum. Histopatliologically, the excised nodules were diagnosed as amyloidosis. The amyloid protein was identified as protein AL by potassium permanganate treatment.
