Introduction: It is rare for primary tumors to arise from the mesentery. Lymphangiomas appear as congenital malformations ofthe lymphatic system or benign neoplasms as a large, thin-walled, often multilocular cyst. Mesenteric infiltration is common andduring surgical treatment, adjustment of structures such as the bowel and resection of the spleen may be required. Cystic mesotheliomasare rare, benign tumors that originate from the peritoneal mesothelium and are more common in women. Mesenteric cystsare mostly benign and rare intra-abdominal tumors, and can be seen as occupying a large cyst. Malignant fibrous histiocytoma isa rare pleomorphic sarcoma that is more commonly encountered in men. After the extremities, the second most common areas tobe affected are the retroperitoneum and peritoneal cavity.Case Presentation: We encountered four cases of different primary mesenteric neoplasms that were operated at the Gazi Yasargilteaching and research hospital, department of general surgery, Diyarbakir, Turkey, between 2013 and 2014. We reviewed these primarymesenteric neoplasms and compared them with previous literature.Conclusions: Primary mesenteric tumors are rare and mostly benign tumors. Complete surgical excision is necessary for all tumorsand follow-up is necessary after surgery for malignant fibrous histiocytoma due to recurrence.
