• X-ray findings of peripheral lung cancer were observed in detail under consideration to the histologic change on 34 tumors sized 2 cm or less in diameter with 33 tumors sized 2.1 cm to 3.0 cm.45 adenocarcinoma, 12 epidermoid carcinoma and 10 undifferentiated carcinoma were included in the total cases.<BR>1.The radiological findings of small peripheral lung cancer were classified into three major types, i.e., Tumorous type, Conglomerating type and Infiltrative type, and cavitary shadows were noted in addition.<BR>Tumorous type was classified into 4 subtypes, a) round, b) mulberry-like, c) on-pleural and d) irregular polygonal. Conglomerating type was divided into 2 subtypes, a) nodularly conglomerating and b) granularly conglomerating, and infiltrative type into two;a) pure infiltrative and b) infiltrative with strand. (Fig.1).<BR>2.Regarding pulmoalveolar and papillary adenocarcinoma, most of the cases showed infiltrative shadow, while some of them revealed tumorous density, the border of which were not so sharp and showed somewhat infiltrative nuance on plane film.On tomogram, unevenness on the density of tumorous shadow or accompanying strand and/or string shadows were noted.<BR>3. As for tubular and acinor adenocarcinoma, most cases showed sharply defined tumorous density, or relatively deep notchings like a clover, and were accompanied with radiated strand shadow on either plane film or tomogram in many cases.In low differenciated adenocarcinoma, the tumor tend to show round shape.<BR>4. Commonly to all the subtypes of adenocarcinoma, air bronchogram was observed frequently.<BR>5. It was felt difficult to discern epidermoid carcinoma from undifferenciated carcinoma on the radiological findings.Epidermoid carcinoma, sized under 2 cm, revealed round shadow of mostly well defined margin, but when exceeded 2 cm in diameter, it showed shallow and relatively smooth notchings which looked like a potato in many of the cases, or many strand shadows running along bronchi or pulmonary vessels in some of them.<BR>6. As for undifferenciated carcinoma, some cases showed saw-toothed-like border, while the others had well-defined tumorous shadow with relatively smooth notchings simillar to those of epidermoid carcinoma.<BR>7. In the early stage of epidermoid and undifferenciated carcinoma, granularly conglomerating type appeared.<BR>8. The border of the tumor tended to be hazy, when tuberculous lesions were present around the tumor.<BR>9. In the small peripheral lung cancer, cavitary shadow was found oftener in adenocarcinoma than in the others.
