Morphological analysis of the so-called "female type" of lung cancer has been madecompared with the "male type", concerning the relationship of the cancer histology, age, sex, and site of primary growth with special reference to the smoking habits of the patients. At present, in Japan, the majority of female lung cancer belongs to the so-called "female type". Those cases did not have remarkable smoking habits. The dominant histology of this type was adenocarcinoma, originating in the peripheral portion of the lung. Even in male cases of adenocarcinoma, characteristics similar to those of female cases were noticed concerning the site of origin, age, and also ageadjusted relative risk associated with smoking habits.<BR>About 130 female cases of lung cancer in Hawaii and 28 cases in Tokyo Metropolitan Geriatric Hospital were also examined. A majority of female smokers showed squamous cell carcinoma or small cell carcinoma which was similar to our "male type" cases.<BR>Adenocarcinoma was subclassified into two cell types as follows: 1. columnar cell type, 2. peg-shaped cell type: The peg-shaped cell type of adenocarcinoma appeared with significant frequency in the peripheral portion of the airway.<BR>The growth pattern of adenocarcinoma foci into surrounding lung tissues showed lining growth along the alveolar walls. The author doubts the existence of "bronchioloalveolar cell carcinoma" as a distinct morphological entity in adenocarcinoma.
