Abstract

Amyloidosis of the tonsil is a rare condition and amyloidosis of Waldeyer's ring has not been previously reported. The present study describes a case of amyloidosis of the tonsil, nasopharynx and base of tongue in a 35-year-old patient in otherwise good health and without clinical symptoms. The possibility of systemic amyloidosis was excluded by clinical examination and biopsy of rectal and buccal mucosae. Electron microscopy showed the presence of typical amyloid fibrils. Large masses of the fibrils were closely surrounded by cells which appeared to be phagocytic. The ultrastructure of these cells is described. This case is considered to be a unique type of organlimited amyloidosis of Waldeyer's ring.

Zusammenfassung

Amyloidosis der Mandel ist ein seltener Zustand und über Amyloidosis des Waldeyer Rings wurde bisher nicht be-richtet. In der vorliegenden Studie wird ein Fall von Amyloidosis der Mandel, des Nasopharynx und der Zungen-basis bei einem 35jährigen gesunden Patienten, ohne klinische Symptome, beschrieben. Die Möglichkeit einer systemischen Amyloidosis wurde durch klinische Unter-suchung und Biopsie von rektalen und buccalen Mucosae ausgeschlossen. Elektronenmikroskopie zeigte das Vor-handensein typischer amyloider Fibrillen. Groβe Mengen der Fribrillen waren von Zellen, die phagocytisch erschie-nen, dicht umschlossen. Die Ultrastruktur dieser Zellen wird beschrieben. Bei diesem Fall handelt es sich urn einen einzigartigen Typ organbeschrankter Amyloidosis des Waldeyer Rings.
