家族性に見られた乳頭状口蓋扁桃肥大症の3例

THREE CASES OF PAPILLARY HYPERTROPHY OF THE TONSILS IN A FAMILY

　I．緒言

　通常みられる口蓋扁桃肥大とは異なって，その形態にいささか異常をきたしているものに乳頭状扁桃と振子様扁桃がある。乳頭状扁桃肥大は比較的稀なもので，本邦では現在までに36例の報告をみるにすぎない。筆者らは乳頭状扁桃肥大を認めた3症例1家族を診療する機会を得たので報告し，光顕と走査電顕で扁桃表面を観察し，成因について文献的考察を行った。

　Papillary hypertrophy of the tonsils is relatively rare among morphological abnormalities of the palatine tonsils, and only 36 cases have been reported in Japan.

　We found this disease in three members of a family, and observed the papillary surface of the palatine tonsils by the histopathological examination and scanning electron microscopic examination.

　Tonsillectomies were performed on a 42-year-old male and his daughters of 8-year-old and 12-year-old under general anesthesia. The histopathological examination of the tonsils revealed lymphoid hyperplasia. According to the scanning electron microscopic observation of the papillary surface of palatine tonsil, the surface looks rugged, but micro ridge is observed in the free surface, which is quite similar to the normal tonsil.

　It is thought that the etiology of this disease is genetical or congenital.
