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.

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.
