Mesenteric fibromatosis (MF) is a rare, locally aggressive tumor without distant metastasis, which has a high recurrence rate. Based on its location, it is classified as intra-abdominal, from abdominal wall, and extra-abdominal. The incidence of cystic-solid, retroperitoneal tumors is very low in comparison to other MF forms. Intra-abdominal MFs are asymptomatic in early stages, but their symptoms appear late in the tumor course. There is no specific imaging finding since radiological diagnosis is mostly impossible. Thus, diagnosis is made histopathologically. Nowadays, there is no consensus about its treatment although surgical resection is widely used. In the present study, a very rare case of cystic-solid retroperitoneal MF associated with separate synchronous skin tumors is reported.
