Abstract:
Thirty-five cases of poorly differentiated carcinoma, of the lung were examined under electron microscopy and the results were compared with that of light microscopy. The results of histological typing coincided only in ten cases. Among twenty cases of poorly differentiated squamous cell carcinoma diagnosed by light microscopy, 60% were adenosquamous carcinoma, 20% poorly differentiated adenocar-cinoma, 10% small cell carcinoma and only 10% poorly differentiated squamous cell carcinoma as they were scrutinized under electron microscopy. Among 5 cases of small cell carcinoma diagnosed light microscopically, 2 cases were carcinoid, one case poorly differentiated adenocarcinoma, one case smalt cell carcinoma, and one case lympnoma diagnosed electron microscopically. Among 4 cases of carcinoid diagnosed electron microscopically, 2 cases were small cell carcinoma, one case large cell carcinoma,, and only one case of carcinoid diagnosed light microscopically. The results showed that 40% of all cases were adenosquamous carcinoma as shown by electron microscopy. For purpose of providing more-accurate histological types to the clinician, it is necessary and possible to study electron microscopically the poorly differentiated carcinoma of the lung.
