Background: Mature cystic teratomas (dermoid cysts) are most frequently seen in the reproductive age-group. Torsion is the most common complication of dermoid cysts, with detachment from the adnexa in rare circumstances.
Case description: A 38-year-old patient presented with dull pain in right lower abdominal region. Tenderness was elicited in the right iliac fossa with right forniceal fullness on per vaginal examination. The ultrasound diagnosis of a mature cystic teratoma was confirmed on computerized tomography. Laparoscopy showed torsion of the right adnexa, with the dermoid cyst seen detached and within the pouch of Douglas. The wandering dermoid cyst was removed laparoscopically, en masse using an endobag without spillage.
Conclusion: The rare possibility of detachment of the dermoid cyst with or without the entire ovary exists in cases of torsion necessitating recognition and appropriate surgical removal.
