Summary :
Backgrounds: Amyloidosis is a rare pathology, due to a toxic accumulation of amyloid proteins infiltrating tissues. Published studies have low statistical power. However it seems that ENT localization have favorable prognosis. Management and check up are not well codified. Methods: Bicentric retrospective study conducted between 1987 and 2015, from patient diagnosed with ENT amyloidosis. The study was performed to the database of the pathology department. People concerned, history, symptoms and diagnostic features were analysed. The immunologic and clinical status, locations, extension check, treatment and prognosis have been evaluated. Results: twenty patients were evaluated, ten men and ten women, average age was 55.5 year of age. Three patients were afflicted with familial amyloidosis. Main localisation was larynx (80%), main type was immunoglobulinic (AL) (80%). Amyloidosis was mostly localised (90%) and primary form (80%). Dysphonia was the most frequently encountered symptom. Most performed examination were local biopsy and creatinine clearance (100%), serum protein electrophoresis (SEP) (89%), myelogram and/or bone marrow aspiration (75%), and trans thoracic echography (TTE) (75%). Surgical removal was performed for 75% of the patients. Global rate of recurrence was 70%, about 4.6 years after diagnosis. In familial forms, overall survival was 66% at ten years. In non-familial forms, overall survival was 100%. Conclusion: ENT amyloidosis are mostly AL, laryngeal, primary and localised. Distant extension check should be managed by internal medicine specialist and associate creatinine clearance, local biopsy, TTE, SEP and myelogram. Head and neck forms treatment is based on surgical removal, familial forms are of poor prognosis.
