| 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. Most such tumors form glandular structures containing mucin, although a minority are solid and without mucin. Growth is slow, but there may be early invasion of blood and lymph vessels, giving rise to metastases while the primary lesion is still asymptomatic. Two types are distinguished, bronchogenic a. and bronchioloalveolar carcinoma.
