This paper presents the results of an attempt to measure the change in general mental alertness which followed the operation for diseased tonsils and adenoids. The comparisons made in this study involve the use of a control group with adenoids which did not undergo the operation. Only one other investigator has taken advantage of the fact that the best control group would consist of those suffe...

Lymphangiomatous polyps of the palatine tonsils are uncommon hamartomatous proliferations that could be clinically misdiagnosed as malignant neoplasms. These polyps consist of dilated lymphatic vessels located inside fibrous and/or adipose tissue. In this paper, a 27-year-old man who presented to the outpatient clinic with a complaint of dysphagia is presented. On physical examination, the pati...

The incidence of oropharyngeal carcinoma, involving palatine and lingual tonsils, is increasing globally. This significant rise is driven by human papillomavirus. Whether palatine tonsillectomy affects risk of diagnosis with oropharyngeal carcinoma is unknown. The association between tonsillectomy and incidence of oropharyngeal carcinoma was explored in the Danish Cancer Registry. The associati...

ヒトの口蓋扁桃, とくにその肥大症と慢性炎症に関する病理組織学的研究は今日まで多 数みられ, 枚挙にいとまがない程である. しかし, 口蓋扁桃の年令的変化に焦点をしぼっ た研究は比較的乏 しい. 文献をみると, LEVINSTEIN (1909), 富田 (1923), 山末 (1941), 鈴 木 (1955) らはヒトの口蓋扁桃は14才頃を境にして, 大野 (1954) は10才 頃を境にして 退化 に向かうとしている. これ らの研究の多 くはその目的とする所が別にあるので, 扁桃の年 令的推移とい う点ではやや説得力を欠 くうらみがあり, 再検討を要する. ところで, リンパ節や脾などの リンパ性器官の生後の発育と退縮の過程は二次小節の分 化の程度にほぼ平行することが確認されている (AWAYA and ODA 1965). そこで, リン パ性器官の一つである口蓋扁桃におい...
