Case Report of Bilateral Dermoid Cyst Containing Tooth and Bone with Unilateral Ovarian Torsion

A case of bilateral dermoid cyst accompanied by unilateral over-torsion with acute abdomen was presented. A 35-year-old patient presented with acute abdomen in the emergency department. Two complete rounds of torsion and bilateral dermoid cysts were detected during the surgery. Left salpingoformectomy and right cystectomy were performed. During cystectomy, together with the hair one incisor tooth and bone like tissue was detected. Dermoids are mature teratomas arising from the germ cells, and therefore they can contain elements of all three germ cell layers such as epidermis, hair, calcified bone, teeth, fat and soft tissue like in our case. Since bilaterality is a common feature of dermoids, it should be examined in the opposite over dermoid cyst, even in cases of emergency unilateral torsion, so that future multiple torsion cases can be prevented
