Differential diagnosis between poorly differentiated epidermoid and small cell carcinoma by means of scanning electron microscopy and cytokeratin assay.
18 cases of small cell carcinoma were studied by means of scanning electron microscopy and immunohistochemical analysis. 4 cases showed ultrastructural and immunohistochemical features of poorly differentiated epidermoid carcinoma. A strict correlation has been demonstrated between ultrastructural and immunohistochemical findings.
