title: Cystic duplication of the cecum lined by dermal type squamous epithelium.
abstract: This is a case report of a cystic duplication of the cecum in a 6-month-old female infant, which was lined by both columnar and squamous epithelium. This squamous epithelium did not resemble esophageal epithelium but dermal epithelium. The so-called split notochord theory can explain the possibility of the coexistence of ectoderm and entoderm components. However, the present case had no vertebral abnormalities.
