Sarcomatoid Peritoneal Mesothelioma: Clinicopathologic Correlation of 13 Cases
EN Pavlisko, VL Roggli. Duke University Medical Center, Durham, NC
Background: Peritoneal mesothelioma is rare and the sarcomatoid variant is more infrequent. Several case series have described the morphologic features of sarcomatoid peritoneal mesothelioma (SPe); however, the clinicocopathologic features are not well characterized.
Design: We reviewed our database of 2859 mesothelioma cases, of which 2524 (88%) were pleural and 335 (12%) were peritoneal. Of the peritoneal mesotheliomas, 252 (75%) were epithelioid, 70 (21%) were biphasic, and 13 (4%) were sarcomatoid variant.
