[Localized amyloidosis in the tonsil].
A 71-year-old male consulted our hospital complaining of right tonsil enlargement. Tonsillectomy was performed. Histological analysis demonstrated AL amyloid deposits obliterating the tonsillar structures. Foreign body giant cell reaction and morphologically normal plasma cells mainly containing light chain lambda were present around the amyloid. Serum immunoglobulin levels were normal and M-proteins were not detected. Urinary test for Bence Jones proteins was negative. Bone marrow aspirates did not demonstrate any signs of multiple myeloma. Amyloidosis of the stomach, colon, heart, and skin was ruled out. We report an extremely rare case of amyloidosis localized in the tonsil and review the literature.
