The Answer is Cancer III

A 35 year old woman presents to her gynecologist and is incidentally found to have a cystic ovarian mass. She is asymptomatic, but ovarian cystectomy is recommended to prevent torsion, rupture, and a 0.2-2% chance of malignant transformation, usually into a squamous cell carcinoma.

Challenge: What's the diagnosis?

The Answer is Cancer III

This is an ovarian teratoma, the most common type of germ cell tumor. Mature cystic teratomas or dermoid cysts are made up of mature tissue of ectodermal, mesodermal, and endodermal origin and appear as a multicystic mass with hair, teeth, and/or skin mixed with sebaceous, thick, sticky material. Here, teeth can be visualized on X-ray.
