Mesenteric dermoid cyst may present as asymptomatic mass, abdominal pain and acute intestinal obstruction due to volvulus has been reported According to English literature and PubMed data base only 21 cases of mesenteric dermoid cysts are reported.

Herein, we are reporting an extremely rare case of mesenteric dermoid cyst in a 35 years’ adult male patient. Clinically he presented with a lump in abdomen at right ileac fossa, pain in abdomen and diagnosis of mesenteric cyst confirmed on abdominal ultrasonography. We performed complete enucleation of a large mesenteric dermoid cyst without resection anastomosis of small bowel.
