Acinar Cell Carcinomas

《英文msh詞典》Acinar Cell Carcinomas
[入口詞] Acinar Cell Carcinomas
[主題詞] Carcinoma,Acinar Cell
[英文釋義] A malignant tumor arising from secreting cells of a racemose gland,particularly the salivary glands. Racemose (Latin racemosus,full of clusters) refers,as does acinar (Latin acinus,grape),to small saclike dilatations in various glands. Acinar cell carcinomas are usually well differentiated and account for about 13% of the cancers arising in the parotid gland. Lymph node metastasis occurs in about 16% of cases. Local recurrences and distant metastases many years after treatment are common. This tumor appears in all age groups and is most common in women.
