Abstract
|
|
|
International Association for the Study of Lung Cancer(IASLC) recommended the following classification of small cell lung carcinoma(SCLS):(1) Small cell carcinoma (2) Mixed small cell/large cell carcinoma (3) Combined small cell carcinoma.
Combined
small cell carcinomas contain a squamous cell carcinoma or adenocarcinoma component. The prognostic significance of these elements is not known, but since the frequency and extent of non-small cell elements are considerably greater in posttherapy
and
autopsy tissues, it is possible that the non-SCLC elements are more resistant to therapy than the SCLC cells.
Metaplasia & dysplasia of the bronchial surface epithelium are frequently observed in the bronchial biopsy. Specimens that contain small cell carcinoma of the lung.
We report a case of combined small cell carcinoma with squamous element associated with microinvasive squamous cell carcinoma of the bronchial surface epithelium in 68 year old male patient. Stage was IIIa. The two lesion are not connected in
serial
sections.
