Abstract

Localized amyloidosis is a rare condition characterized by the deposition of misfolding protein in a tissue, without other systemic manifestations. Only a small number of cases of localized amyloidosis of the tongue have been reported to date, in contrast to systemic amyloidosis, in which localization on the tongue is common. This study presents a rare case of localized amyloidosis of the tongue (amyloidoma) and provides a summary of the known literature of localized amyloidosis. This study describes the case of a 36‑year‑old female who presented with a swelling of the tongue base. The diagnosis of amyloidoma was made based on the findings of the physical examination, head and neck MRI findings and the histopathological examination with Congo red stain under polarized light. The histopathological diagnosis was as follows: Localized lambda light‑chain amyloidosis. A thorough physical examination was performed by the ENT and Hematology/Oncology departments, without revealing signs of systemic disease. A series of hematological and imaging tests were also performed to verify that there was no sign of systemic involvement. The patient declined surgical excision and the 2‑year follow‑up did not reveal any changes in tumor dimension. Although the etiology of localized amyloidosis is yet not clear, the prolonged reaction of tissue plasma cells to environmental antigens may be a causative factor for the initiation of the neoplastic process.
