We describe a case of primary localized nodular tongue amyloidosis ass
ociated with Sjogren's syndrome in a 62-year-old woman. The presence o
f Sjogren's syndrome was confirmed both serologically and histological
ly. The amyloid tumor, which was marginally excised, recurred 3 years
later and was reexcised. Immunohistochemical examination revealed that
the amyloid protein was of the AL (lambda-light chain) type. Infiltra
tion of plasma cells was observed around the minor salivary glands of
the tongue surrounded by amyloid. The relationship between the plasma
cells and amyloid deposition is discussed.
