A 32-year-old woman visits her gynecologist for a Pap smear. On physical examination, her gynecologist palpates
a large adnexal mass on the right. After ultrasound confirmation of a large ovarian mass, a laparotomy is
scheduled, and the mass is removed. Pathologic examination of the mass demonstrates a cystic cavity filled with
hair and keratin debris, and the wall contains skin, adnexal tissue, thyroid tissue, and neural tissue. All of the
tissues are similar to those normally found, and no malignant changes are seen. Which of the following is the
most likely diagnosis?
A. Immature teratoma
B. Leiomyoma
C. Leiomyosarcoma
D. Mature teratoma
E. Rhabdomyosarcoma
