설기저부의 소타액선에 발생한 투명세포선암종 1례

초록

It is reported that tumors occurring on minor salivary glands represent less than 10 percent of total salivary gland tumors. In particular, the occurrence of clear cell adenocarcinoma is very rarely observed. Thus, it is hard to measure the exact occurrence rate. Nevertheless, it is assumed that clear cell adenocarcinoma covers less than one percent of all salivary glands tumors. Clear cell adenocarcinoma shows similar histological morphology with salivary gland tumors such as mucopeidermoid carcinoma, acinic cell carcinoma, epithelial and myoepithelial tumors. However, its differential diagnosis with other tumors is possible because it shows the unique monomorphous clear cells. Authors observed the clear cell adenocarcinoma of minor salivary glands at tongue base in a 60 year-old female patient who was complaining about a foreign body sensation on the pharynx.
