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.

al·ve·o·lar cell car·ci·no·ma

a carcinoma, subtype of adenocarcinoma, thought to be derived from epithelium of terminal bronchioles, in which the neoplastic tissue extends along the alveolar walls and grows in small masses within the alveoli; involvement may be uniformly diffuse and massive, or nodular, or lobular; microscopically, the neoplastic cells are cuboidal or columnar and form papillary structures; mucin may be demonstrated in some of the cells and in the material in the alveoli, which also includes denuded cells; metastases in regional lymph nodes, and even in more distant sites, are known to occur, but are infrequent.
