Squamous cell Ca ◆30-40%，generally central(70% hilar or perihilar in subsegmental or larger bronchi) .strong association with cigarette smoking about 15%bronchogenic carcinomas are cavitary,and of these,nearly 60%are squamous cell lesions,wall typically thick and nodular

.intralumenal growth pattern- often resulting in distal atelectasis or post-obstructive pneumonitis (a non-infectious process). .the lowest frequency of distant metastases,spreads to involve local nodes by direct extension .the most favorable prognosis Hypertrophic osteoarthropathy

adenocarcinoma ◆ as common as squamous cell carcinoma (30-40%). generally peripheral (75%) uncommonly cavitate commonly metastasizes early to lymph nodes,the pleura,adrenal glands,CNS,and bone

Small cell Ca .15-20%of primary lung malignancies the strongest association with cigarette smoking the most likely to produce ectopic hormones-most commonly resulting in Cushings syndrome (ACTH)or syndrome of inappropriate antidiuretic hormone (SIADH)

◆ generally central (85-90%within a lobar or mainstem bronchi)and has a tendency to invade longitudinally along the bronchial wall,in a submucosal and intramural fashion Internal necrosis is common,but cavitation is extremely rare the worst prognosis,despite typically good response to initial chemotherapy

Large Cell Ca ◆only5-10% strongly associated with cigarette smoking typically peripheral and generally large (over 4 to 6 cm),with rapid growth,early metastases,and a poor prognosis
