Well-differentiated papillary mesothelial tumor (WDPMT) is an uncommon tumor, formerly named well-differentiated papillary mesothelioma in the 2015 World Health Organization classification. It has a characteristic papillary architecture, bland cytologic features, a tendency toward superficial spread without invasion, and a good prognosis due to its clinically indolent behavior with prolonged survival. Rare cases with superficial invasion are termed WDPMT with invasive foci. WDPMT occurs primarily in the peritoneum of reproductive- age women, but also rarely in the pleura. We report a case of a 60-year-old woman who developed WDPMT with minimal invasion in the pleura with atypical radiological features and a family history of mesothelioma and indirect asbestos exposure.
