口蓋扁桃のlymphangiectatic fibrous polypの1症例

Lymphangiectatic Fibrous Polyp of the Palatine Tonsil: Report of a Case

I．はじめに

　振子様扁桃はJurasz^1）により最初に報告されてから欧米，本邦ともに数多くの記載^2〜8）をみるが，扁桃に生じた有茎性腫瘤，なかでもlymph—angiectatic fibrous polypの報告は著者らが調べえた限り，欧米で2例^9,10），本邦で6例^11〜14）にとどまる。今回われわれは肉眼的形態により口蓋扁桃の振子様腫瘤と診断し両側口蓋扁桃摘出術を行い，光学顕微鏡および透過型電子顕微鏡によりlymph—angiectatic fibrous polypと病理診断された症例を経験したので，文献的考察を含め報告する。

Although patients with pendulous tonsil havebeen frequently reported, there are very few reports of lymphangiectatic fibrous polyp of the palatine tonsil.

In this study, a 36-year-old man with lymph-angiectatic fibrous polyp of the palatine tonsil was reported.

He complained of foreign body sensation on swallowing and a pendulous polyp from the lower pole of the left tonsil was found. The polyp wasremoved with the tonsil and it was examined with a light and electron microscope.

The main histological findings were dilated lymphatic vessels and abundant collagen fibrils. The etiology of this tissue has been remained un-known. We, however, suggested that recurrent infection could produce the lymphangiectatic changes on a pendulous tonsil.
