Mature solid teratoma of the fallopian tube associated with uterine leiomyomas.

Benign solid teratomas within the fallopian tube are rare. The incidence of this kind of benign solid teratoma of the fallopian tube associated with intrauterine leiomyomas is extremely low and may complicate the clinical manifestations. Here, we report a 40-year-old female with periodic lower abdominal pain and hypermenorrhea who was found to have 3 nodules within the uterine myometrium and left distended fallopian tube. Final pathology revealed benign solid teratoma of the fallopian tube associated with 3 intrauterine leiomyomas. Primary teratoma of the fallopian tube is extremely uncommon. Gynecologic oncologists should be aware of the possibility of this disease entity when making differential diagnoses.
