adenocarcinoma

 [ad″ĕ-no-kahr″sĭ-no´mah]
carcinoma derived from glandular tissue or in which the tumor cells form recognizable glandular structures. The World Health Organization recognizes four categories of adenocarcinoma: acinar, papillary, bronchioalveolar, and solid carcinoma with mucus formation; it can be further subclassified into well, moderate, and poorly differentiated forms.
alveolar adenocarcinoma (bronchioalveolar adenocarcinoma) (bronchiolar adenocarcinoma) (bronchioloalveolar adenocarcinoma) (bronchoalveolar adenocarcinoma) bronchioloalveolar carcinoma.
clear cell adenocarcinoma a rare malignant tumor of the female genital tract, resembling a renal cell carcinoma and containing tubules or small cysts with some cells that are hobnail-shaped and others whose cytoplasm is clear, containing abundant glycogen and inconspicuous stroma. It may occur in the ovary, uterus, cervix, or vagina. One form has been linked to in utero exposure to diethylstilbestrol. Called also clear cell carcinoma and mesonephroma.
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.

ad·e·no·car·ci·no·ma

(ad'ĕ-nō-kar'si-nō'mă),
A malignant neoplasm of epithelial cells with a glandular or glandlike pattern.

ductal adenocarcinoma of the prostate  adenocarcinoma of columnar epithelium in the peripheral prostatic ducts; it may project into the urethra.
endometrioid adenocarcinoma  the most common form of endometrial carcinoma, containing tumor cells differentiated into glandular tissue with little or no stroma.
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.
adenocarcinoma of the prostate  acinar a. (2)

adenocarcinoma

[ad′ənōkärsinō′mə] pl. adenocarcinomas, adenocarcinomata
Etymology: Gk, aden + karkinos, crab, oma
any one of a large group of malignant epithelial cell tumors of the glandular tissue. Specific tumors are diagnosed and named by cytological identification of the tissue affected; for example, an adenocarcinoma of the uterine cervix is characterized by tumor cells resembling the glandular epithelium of the cervix. adenocarcinomatous, adj.

Adenocarcinoma

adenocarcinoma

A carcinoma that arises in a secretory epithelium or mucosa—i.e., glands—which is the malignant counterpart of an adenoma.

adenocarcinoma (bladder)

A tumour that may be primary and result from differentiation of a urothelial carcinoma. It may arise in a polyp or from urachal remnant tumours and resemble colorectal tumours, or it can be the recipient of prostate or colorectal metastases.

adenocarcinoma

AdenoCA Oncology A carcinoma that arises in a secretory epithelium or mucosa; it is the malignant counterpart of an adenoma. See Clear cell adenocarcinoma, Minimum deviation adenocarcinoma of the endocervix. Cf Adenoma.

ad·e·no·car·ci·no·ma

(ad'ĕ-nō-kahr'si-nō'mă)
A malignant neoplasm of epithelial cells in glandular or glandlike pattern.

adenocarcinoma

A cancer arising from gland tissue in a lining membrane (EPITHELIUM) and usually showing the glandular features of the original tissue. Most cancers of the breast and large intestine (COLON) are adenocarcinomas.

Adenocarcinoma

A malignant tumor that arises within the tissues of a gland and retains its glandular structure.

adenocarcinoma

carcinoma derived from glandular tissue or in which the tumor cells form recognizable glandular structures. Some are listed under the tissues or organs they invade.

adenocarcinoma of the ileum
a higher than usual prevalence is described in sheep and cattle in some very localized geographical areas, and a relationship to a high intake of bracken hypothesized. The lesions may be symptomless or cause intestinal obstruction. See also pteridium.
nasal adenocarcinoma
see enzootic nasal adenocarcinoma.
renal adenocarcinoma
causes little clinical abnormality in large animals but may be detectable as kidney enlargement during physical examination.
vaginal adenocarcinoma
occurs in white-faced sheep in high sun radiant areas due to short tail dock length or Mule's operation.

On the other hand, most patients with synchronous endometrial and ovarian carcinomas are young and have well-differentiated endometrioid adenocarcinomas, and most patients in this situation probably have concurrent primary carcinomas of endometrium and ovary.
Since there was no difference in cyclin D1 expression between complex hyperplasia and endometrioid adenocarcinoma, it appears that the deregulation is maximal at the complex hyperplasia state and that other alterations may be responsible for the different morphologic features and behavior of complex hyperplasia and carcinoma.
