[Unusual localization of an abdominal dermoid cyst]

A case of epidermoid cyst with rather unusual localization is reported. The cyst ran from the rear cavity of the omentum, penetrating between the leaves of the mesentery rott as far as the angle formed by the caecum and the final ansa before returning along the last ansa for about 20 cm, and compressing it to the point of creating an acute occlusive syndrome. Photographs and radiographs of the case are presented.
