Parasitic dermoid cyst of the pouch of Douglas: a case report.
Extragonadal mature cystic teratomas (dermoid cysts) are reported occasionally, with the most common site being the omentum. Of the 3 proposed causes of such cysts, torsion of a pre-existing dermoid, leading to autoamputation and subsequent reimplantation, is most likely the preceding event. A rare case of a parasitic benign cystic teratoma was incidentally found in the pouch of Douglas in a 29-year-old woman undergoing a laparoscopic right cystectomy for an ovarian dermoid cyst. A literature review indicates that this is the third reported case of a parasitic or wandering dermoid cyst of the pouch of Douglas.
