title: Giant primary amyloidoma of the tonsil.
abstract: A case of giant amyloidoma in the left tonsil with extensive osseous metaplasia and a scanty and patchy monoclonal population of IgG Kappa plasma cells, is presented. Localized tumoral amyloidosis is a rare, benign tumour of the upper aerodigestive tract. Organ-limited amyloidosis has been shown to be confined to various systems but, since the lesion was first described, only four cases situated in the tonsils have been reported in the English literature, and none of these had either osseous metaplasia or a monoclonal population of IgG Kappa plasma cells.
