Fimbrial dermoid cyst with elevated CA19-9 levels: A case report

Mature cystic teratoma of the fallopian tube diagnosed preoperatively with computed tomography and ultrasound: A case report

Mature cystic teratoma of the fallopian tube is extremely rare, with fewer than 100 cases reported in the English literature. Clinical symptoms are nonspecific, and the diagnosis is most often made after surgical resection. A preoperative diagnosis has the potential to aid with surgical planning and patient counseling. We present a case of a large completely intratubal mature cystic teratoma in a 40-year-old woman who presented to her primary care provider with the gradual onset of right lower quadrant/pelvic pain. The patient's symptoms prompted evaluation with computed tomography (CT) and ultrasound. Imaging showed a dilated right fallopian tube containing fluid, macroscopic fat, and calcifications, facilitating the preoperative diagnosis of mature cystic teratoma of the fallopian tube. Because of her symptoms, she elected to undergo salpingectomy and the diagnosis was pathologically confirmed. The patient's symptoms resolved following surgery.

Contralateral Fallopian Tube Dermoid Tumor: A Rare Finding in Chronic Tubal Ectopic Gestation

Mature cystic teratoma is the most common benign tumor of the ovaries in women of reproductive age. Dermoid tumor in an ectopic or aberrant location is usually detected incidentally. The occurrence of a dermoid tumor in the fallopian tubes is extremely rare, with only approximately 75 cases being reported worldwide in the English language literature. This report describes a left-sided fallopian tube dermoid tumor in a 27-year-old woman with chronic right tubal ectopic gestation and discusses its clinical implications. Inspection of the contralateral fallopian tube in a woman with a ruptured tubal ectopic pregnancy is required clinically to rule out bilateral tubal ectopic gestation. Although rare, the ectopic presence of a dermoid tumor in the fallopian tube may be an incidental finding requiring surgical removal.
