Abstract

Mesothelioma originates in several sites including the pleura, peritoneum, pericardium, and tunica vaginalis. The pleura is the most common site of origin, but cases originating in the per- itoneum is relatively rare. Mesothelial lesions of the peritoneum may pose significant diagnostic problems. Yet, the accurate identification of this lesion is important because of its distinctive behavior and treatment modality. We herein report a case of malignant mesothelioma of the peritoneum arising in the capsule of the liver. The accuracy of our diagnosis has been confirmed by the immunohistochemical study and electron microscopic examination.
