악하선에 발생한 점액낭종 1례

Cysts of the salivary glands are very rare and non-neoplastic, localized lesions of the duct system. There are three types, namely, dysgenetic cyst, secondary acquired cyst lined by epitheliumCduct cyst, lymphoepithelial cyst, and retention mucocele), and pseudocyst without an epithelial liningCextravasation mucocele). The non-neoplastic cysts and pseudocysts form about 6% of lesions of the salivary glands.

Among the limited number of cystic submandibular gland neoplasms reported in the literatures, there have been few reports, to our knowledge, of a similar cystic lesion.

Recently the authors experienced an unusual case of huge extravasation mucocele arising from the submandibular gland. The mucocele was completely removed surgically, which was confirmed by histochemically.
