Localized amyloid tumor of the tongue. A case report and review of the literature.
Amyloid is usually deposited in the tongue, as a part of generalized amyloidosis. Isolated localized amyloidosis of the tongue is relatively rare. We report such a case which presented with glossodynia and glossopyrosis and was thought clinically to represent median rhomboid glossitis. Histologically the amyloid stained positively with Congo-red giving green birefringence under polarized light, was not abolished after permanganate pretreatment and did not react immunohistochemically for amyloid A, beta 2 microglobulin and transthyretin.
