two developmental patterns could be observed : one characterized by the persistent action of carcinogens on a substrate similar or less different as to the normal one , giving rise to the microcellular , pleomorphous and epidermoid carcinomas , and the other related to the pre-existence of fibrous lesions in the lung which enhance the accumulation of carcinogens and provide for the cylindrocubic , bronchioloalveolar carcinomas and for the pseudoglandular zones of pleomorphous ones .
