Haemodialysis associated amyloidosis of the tongue: a case report6

ABSTRACT

Haemodialysis associated amyloidosis (HAA) is a complication of long-term haemodialysis caused by deposition of β2- microglobulin in tissues that most often presents clinically at osteoarticular sites. However, in very rare circumstances, patients do present initially with oral manifestations of HAA. In a normally functioning kidney, β2- microglobulin is cleared by glomerular filtration and is catabolized in the proximal tubules. This article describes a patient with oral manifestation of haemodialysis associated amyloidosis with an unusual presenting complaint of lingual dysaesthesia.
