Unusual pathology of colon: inclusion dermoid cyst.

Dermoid cysts are typically known to occur in the midline, near the lines of embryonic fusion, from trapped ectodermal tissue. They are very rare in the gastrointestinal tract, and only a few cases of dermoid cyst in the caecum and ileum have been reported in the literature. In our case, a dermoid cyst was found in the transverse colon, which has not been reported previously.
