Introduction:
Amyloidosis is characterized by extracellular deposits of proteins.
Observation:
A 66 year-old patient presented with a pseudo-tumoral amyloidosis of the cavum. Clinical and biological examinations confirmed the localized aspect of the disease and immunohistochemical exploration identified a type AL amyloidosis.
Comments:
The disease may be diffuse involving many organs and leading to various clinical manifestations. It can also be localized and take on a pseudo-tumoral aspect. Localised amyloidosis is a rare lesion of the upper aero-digestive tract, predominating in the larynx. Nasopharyngeal involvement is exceptional.
