Abstract

Metastases to inguinofemoral lymph nodes in patients with carcinoma of the vulva alter the prognosis and treatment of this disease. Our goal was to determine if immunohistochemical staining could reveal occult metastatic nodal disease not detected with routine hematoxylin and eosin staining. We retrospectively examined a total of 110 lymph nodes from 10 patients who had undergone lymph node dissection and found to have all negative node. Paraffin embedded lymph nodes were immunostained with a monoclonal antibody directed against multiple low- and high molecular weight cytokeratins. Micrometastases were not detected in any lymph nodes examined with immunohistochemistry. All positive and negative controls yielded satisfactory results. It is concluded that immunohistochemistry with cytokeratin antibodies does not provide greater sensitivity than routine hematoxylin and eosin staining for the detection of nodal metastases in vulvar carcinoma.
