Diffuse malignant mesothelioma arising in a paracolostomy hernial sac

Clear cell mesothelioma presenting as an incarcerated abdominal hernia

“…In many of these patients, the diagnosis of mesothelioma is established only after they seek medical attention due to discomfort resulting from the accumulation of ascites fluid in the hernial sac. Although, in most instances, the resected hernial sac only contains ascites fluid, on rare occasions, it can be involved by either an extension of or a metastasis from a peritoneal mesothelioma that has spread into the preestablished hernial sac [2,3,10,11,27]. The present case is unusual not only in that the abdominal ventral hernia was the presenting symptom of the mesothelioma, but also because of the unusual clear cell morphology of the tumor.…”

Primary Malignant Peritoneal Mesothelioma in an Incarcerated Groin Hernia: Report of a Case

“…8 Our recent updating review of the literature revealed only six cases of primary mesothelioma of the hernia sac. [2][3][4][5][6][7] The patients, who were all men, ranged in age from 33 to 87 years and because of the lack of characteristic clinical symptoms, the preoperative diagnosis was never established or even firmly suspected. Most of these tumors were found intraoperatively.…”

“…1 Malignant peritoneal mesothelioma (MPM) accounts for less than 10%-20% of all malignant mesotheliomas 1 and very few cases of MPM appearing to arise from the inguinal hernia sac have been reported. [2][3][4][5][6][7] These tumors are usually found incidentally during surgery and, in contrast to pleural and peritoneal diffused malignant mesothelioma, they are not hypertension, but confirmed the presence of intestinal loops in both inguinal hernia sacs. Emergency exploratory surgery revealed a firm mass, 10 cm in diameter, in the left inguinal hernia sac (Fig.…”
