Synchronous occurrence of mature cystic teratoma of the fallopian tube and ovary: A case report.

Primary carcinoma of the fallopian tube represents <1% of all gynecological tumors, and benign tumors of the fallopian tube are encountered even less frequently. Mature teratomas of the fallopian tube and ovary are extremely rare, and to date, only a few cases have been reported. A 31-year-old woman presented with a left adnexal mass that was identified by pelvic ultrasonography during a regular checkup. The patient underwent laparoscopic left salpingectomy and left ovarian cystectomy. Histopathological examination of the removed tissue revealed features compatible with mature cystic teratomas of both the left fallopian tube and ovary. At 26 months post-surgery, the patient underwent a cesarean section at 39+2 weeks of gestation. A right ovarian cystic mass was incidentally identified during the procedure. Right ovarian cystectomy was performed, and histopathological analysis revealed the mass to be a teratoma. The patient continued to receive annual follow-up after surgical intervention and demonstrated no evidence of disease at a routine 2-year follow-up examination. The discussion of the present case is followed by a brief review of the literature.
