Ectopic salivary gland tissue : ウィキペディア英語版 | Ectopic salivary gland tissue Salivary gland tissue which is located in sites other than the normal location is variously described as aberrant, accessory, ectopic, heterotopic or salivary gland choristoma. ==Accessory salivary glands== An ''accessory salivary gland'' is ectopic salivary gland tissue with a salivary gland duct system. The most common location of accessory salivary gland tissue is an extra major salivary gland in front of the parotid gland. It is typically about 3 cm or less in size, and drains into the parotid duct via a single tributary.〔 Accessory parotid tissue is found in 21-56% of adults.〔 Any disease process which affects the salivary glands, including cancer, may also occur within an accessory salivary gland tissue.
