Polymorphous low-grade adenocarcinoma, often abbreviated PLGA, is a rare, asymptomatic, slow-growing malignant salivary gland tumor. It is most commonly found in the palate. The name of the tumor derives from the fact that: *It has a varied microscopic architectural appearance, i.e. it is ''polymorphous''. *It is non-aggressive when compared to other oral cavity tumors, i.e. it is a ''low-grade'' tumor.〔 *It forms glands, i.e. it is an ''adenocarcinoma''. It affects the minor salivary glands in the area between the hard and the soft palate. Male to female ratio is 3:1, and the average age is 56 years. ==Histology== PLGAs consist of a monomorphous cell population that has a varied histologic morphology. Microscopically, its histology can be confused with an adenoid cystic carcinoma and a pleomorphic adenoma. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Polymorphous low-grade adenocarcinoma」の詳細全文を読む スポンサード リンク
