BACKGROUND: Pure, benign @entity4890 of the abdominal viscera are rare. There have been only four reports of @entity4890 of the cecum in the literature, two following appendectomies and attributed to the surgical procedure, and two in female @entity1 , raising the possibility of @entity48 related to the ovaries. @entity1 AND METHODS: We report the first case of @entity4890 of the cecum in an elderly @entity1 with no previous history of @entity130 or surgery, detected by computed tomography as an incidental finding of extraluminal cystic cecal mass. It was treated by partial colectomy. Pathologically the cyst was roughly spherical, extending from and expanding the serosal surface of the cecum with no communication through the muscularis wall. Histologically the inner lining of the cyst was composed of benign, mature, keratinized, stratified squamous epithelium with a well formed granular layer. No @entity730 , hair, teeth, or bone elements was detected. RESULTS: The interesting finding in our case is the unusual anatomical location and the age and sex of the @entity1 . The @entity1 had no history of any abdominal surgical procedures. The most likely explanation for the presence and development of an @entity4890 in this location is the result of an aberrant ectodermal implantation during embryogenesis. CONCLUSION: Awareness of the possibility of the presence of @entity4890 in this area with distinctive radiological findings consistent with a well circumscribed benign cyst should be considered in the differential diagnosis of cysts within the abdomen.
