Rare case report: mesocolonic dermoid cyst.

Mesenteric cysts are one of the most rare intra-abdominal tumours [1], classified as chylolymphatic, mesothelial (simple), enterogenous, urogenital remnant, dermoid cyst (teratomatous), gas, mycotic, parasitic, tubercular cysts and cysts following malignant degeneration [2]. Dermoid cysts are uncommon mesenteric cysts [3]. Cysts of the mesocolon are rare and usually differentiated from a mesenteric cyst only at the operation [4]. We here report a rare case of a dermoid cyst that was present in the mesentery of the transverse colon.
