巨大なる顎下腺實質内結石症の1例

　緒言

　唾石症は唾液腺領域に來る結石症で，決して稀有な疾患ではないが，本症が唾液腺実質内に留り増大して行くことは比較的稀である．

　余は最近巨大なる顎下腺実質内結石症で之を口腔内より別出治癒せしめた1例を経驗したので，こゝに報告しようと思う．

Fukuda reports a case of a patient, a man aged 43, with complaints of pain and swelling in right submandibular region and of pus discharge from sublingual salivary duct of the same side. An operation performed through oral approach re-veals a salivary stone which was well embedded in the substance of subligual gland. Analysis of the stone after removal showed its composition as of calcium phosphate and the size of which measured 1.7 cm ×1.3 cm × 1.2 cm with the we-ight of 2.32 gm.

The author states that while records of salia-vry stones listed in the literature are by no means a rare occurrence but those that are dis-covered in the substance of the gland are only a few in number. The present case is the third in the series thus far recorded and apparently the largest in size among the three. In its for-mation, it is believed to be inflammatory in origin.
