clear cell adenocarcinoma

Also found in: Dictionary, Thesaurus, Encyclopedia.


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.

clear cell ad·e·no·car·ci·no·ma

1. a histologic type of renal adenocarcinoma;
2. a histologic type of adenocarcinoma occurring chiefly in the male and female genitourinary tracts that is characterized by distinctive hobnail-cell growth of neoplastic cells in sheets, papillae, and coalescing glands.
A malignancy of the vagina and uterine cervix; 2/3 of such malignancies occur in young women exposed in utero to estrogen analogues, especially DES, as well as hexestrol or dienestrol
Risk The relative risk for DES exposed individuals is 0.014
Prognosis 5-yr survival, 80+% with local recurrence
