Clinical Study and Review of Articles (Korean) about Retrorectal Developmental Cysts in Adults.

Purpose: A retrorectal developmental cyst (tailgut cyst, epidermoid cyst, dermoid cyst, teratoma, and duplication) is very rare disease, and the symptoms are not characteristic so that sometimes this disease is still misdiagnosed as a supralevator abscess or a complex anal fistula. We would like to present a clinical approach to this disease.

Methods: We retrospectively examined the charts of 15 patients who were treated for retrorectal cysts from January 2001 to November 2009.
