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.

The distribution of malignant lesions according to diagnostic yield by FNA shows 100% yield for adenocarcinoma, small cell carcinoma, bronchoalveolar carcinoma and poorly differentiated carcinoma followed by 92% yield for squamous cell carcinoma.
Among the lung tumors FNA showed highest yield for adenocarcinoma, small cell carcinoma, bronchoalveolar carcinoma, poorly differentiated carcinoma and metastatic adenocarcinoma followed by 92.3% for squamous cell carcinoma.
The distribution by histologic findings was as follows: 10.4% (26/ 248) large cell undifferentiated carcinoma, 33% (82/248) adenocarcinoma, 39.1% (97/248) squamous cell carcinoma, and 17.3% (43/248) bronchoalveolar carcinoma.
The distribution of non-small cell lung cancer by histological type was 52 squamous cell carcinomas; 29 adenocarcinomas, including one adenocarcinoma with neuroendocrine characteristics and two bronchoalveolar carcinomas; and 8 large cell carcinomas.
The authors make the insightful point that because of intra-alveolar growth patterns, these tumors can mimic bronchoalveolar carcinomas or adenocarcinomas with papillary features.
