Mesothelioma - Overview of Malignant Mesothelioma Cancer

Abstract Mesenteric cysts are rare benign intra peritoneal tumor and more than half of the mesenteric cysts involve the mesentery of the terminal ileum. We present 8 year-old boy, who presented with features of acute intestinal obstruction. Ultrasonography (USG) of the abdomen revealed a cystic mass in the peritoneal cavity with dilated loops of bowel. Exploration of the abdomen revealed a solitary cyst of the mesentery of the terminal ileum measured 10 x 8 cm. There was twisting of the part of the ileum (volvulus) due to the cyst. It also involved the wall and lumen of the adjacent ileum and there were dilated bowel loops proximal to the cyst. Complete cyst excision and resection of the part of the ileum involved with the cyst was done en bloc. An ileostomy was created due to gross disparity in the lumen of the ileum, which was closed two and half month later. Histopathology of the excised cyst was consistent with the chylolymphatic cyst (mesenteric cyst).

Abstract Although mesenteric cysts in general have been reported in the literature fairly frequently, chylolymphatic cysts in the pediatric age group are extremely rare in the modern medical literature. Ultrasonography and computed tomography suggest the diagnosis but the picture is not clear until demonstrated intraoperatively. Intra-operatively, similar findings can be seen in cystic lymphangioma, retroperitoneal cystic teratoma, caseating tubercular lymph nodes, and hydatid cysts. Even lymphoma and duplication cysts may also give similar appearances. Excision biopsy is then recommended to differentiate these cases. Histopathology is confirmatory and differentiates chylolymphatic cysts from all these lesions. We present our experience with two such cases that presented to our center.
