The β2‐microglobulin amyloidosis is a newly recognized type of systemic amyloidosis, which occurs in patients with chronic renal failure undergoing long‐term hemodialysis. The dialysis‐related amyloidosis (DRA) of the tongue is an uncommon and late complication, which occurs in patients undergoing chronic hemodialysis for more than 20 years. The aim of this paper is to report two cases of lingual amyloidosis associated with long‐term hemodialysis. Two patients were referred to the Oral Medicine Clinic due to the presence of multiple nodules on the tongue and macroglossia. The patients had history of chronic renal failure and had been dialysed for more 20 years with bio‐incompatible cellulose membrane. Biopsies of the lesions were performed and the histopathological features and Congo red stain revealed oral amyloidosis. Both patients remain in clinical follow‐up after 12 and 6 months, respectively. Recognition of the amyloidosis tongue lesions can minimize the complications caused by this condition such as obstruction of the upper airways, making it imperative to carry out early treatment. Furthermore, in patients with oral amyloidosis, lesions in areas of trauma may ulcerate and cause pain and dysphagia becoming necessary periodic surgical removal and regular follow‐up of these patients.
