唾液管末端拡張症について

　まえがき

　耳下腺部の腫脹を反覆する疾患のうち，唾影法の応用により容易に唾液管末端拡張症が診断されるに至った。本症に就いて北村，今井（1959）が詳細に報告しているが今尚誤解されているむきがあるので本症の臨床像，唾影像，組織像に就いてのべ治療経過を報告し更にその病因に就いて考察したい。

The diagnosis of distal dilatation of the salivary duct in cases in whom repeated swelling of the parotid gland may occur is made by X-ray examinations ; the picture will reveal a regularly spotted shadows. Histologically these spots are composed of abnormally dilated vacuoles lined with lami-nated columnar epithelium that are infiltrated by lymphatic cells with tissue hypertrophy. The glandular cells on the other hand become highly atrophic with increase of connective tissue cells in their intervals. The etiology of this disease is inclined to be considered, rather than inflammatory, as congenital and hormo-nal defficiency in origin but seems an unsa-tisfactory an explaination.
