clear cell adenocarcinoma a rare malignant tumor of the female genital tract, containing tubules or small cysts; it may occur in the ovary, uterus, cervix, or vagina. One form has been linked to in utero exposure to diethylstilbestrol.
ductal adenocarcinoma of the prostate adenocarcinoma of columnar epithelium in the peripheral prostatic ducts; it may project into the urethra.

gastric adenocarcinoma any of a group of common stomach cancers, usually located in the antrum; it occurs particularly in Japan, Iceland, Chile, and Finland and may be linked to certain dietary substances such as nitrosamines and benzpyrene.
adenocarcinoma of the lung a type of bronchogenic carcinoma made up of cuboidal or columnar cells in a discrete mass, usually at the periphery of the lungs.
papillary adenocarcinoma , polypoid adenocarcinoma that in which the tumor elements are arranged as finger-like processes or as a solid spherical nodule projecting from an epithelial surface.

| acinic cell adenocarcinoma n. An adenocarcinoma arising from the secreting cells of a racemose gland, particularly the salivary glands. |
acinic cell adenocarcinoma
[asin′ik]
Etymology: L, acinus, grape
an uncommon low-grade malignant neoplasm that develops in the secreting cells of racemose glands, especially the salivary glands. The tumor consists of cells with clear or slightly granular cytoplasm and small eccentric dark nuclei. Also called acinar adenocarcinoma, acinous adenocarcinoma.
adenocarcinoma (ad´
nōkarsinō´m),n a large group of malignant epithelial cell tumors of the glands. Specific tumors are diagnosed and named by the cell type of the tissue affected.
adenocarcinoma, acinic cell,
n a cancer of the salivary glands, primarily the parotid gland.
adenocarcinoma, polymorphous low-grade (PLGA)
n a cancer of the salivary glands, primarily in the minor salivary glands.
