title: Differential diagnosis between poorly differentiated epidermoid and small cell carcinoma by means of scanning electron microscopy and cytokeratin assay.
abstract: 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.
