Abstract

MOC-31 expression has recently been advocated as an immunohistochemical marker for distinguishing mesothelioma from adenocarcinoma in tissue sections. We studied formalin-fixed, paraffin-embedded tissue from 23 pleural mesotheliomas and 23 primary pulmonary adenocarcinomas for immunoreactivity with anti-MOC-31, a human epithelial-related antigen. All of the 23 adenocarcinomas strongly expressed the marker, whereas only one of the mesotheliomas showed weak reactivity. These results demonstrate the usefulness of anti-MOC-31 in differentiating pulmonary adenocarcinoma from mesothelioma.
