title: Ectopic enterogenous cyst.
abstract: Enterogenous cyst is a rare congenital lesion presumably of endodermal derivation. It is usually located in the medistinum, the abdominal cavity, skull or within the spinal canal. To our knowledge, it has not been reported in the subcutaneous tissue. We report the first case of ectopic (left scapular region) subcutaneous enterogenous cyst in a 46-year-old man, who presented with a lump over the left scapular region of several years' duration. Clinical diagnosis of lipoma was made. The final histological diagnosis was enterogenous cyst. Enterogenous cysts at ectopic locations should be kept in mind and studied further especially with respect to their development. A better understanding of the embryology, histopathology and genetics of ectopic enterogenous cyst is desired.
