Cutaneous ciliated cyst of the abdominal wall: a case report with a review of the literature and discussion of pathogenesis.

A cutaneous ciliated cyst is a rare lesion typically found on the lower extremity of young girls shortly after puberty. Here, we report a case involving a previously unreported site (i.e., abdominal wall) in a 14-year-old girl. We also describe immunohistochemical and ultrastructural findings, review and analyze the world literature, and offer insights as to the pathogenesis of this lesion.
