Accessory Fallopian Tube in an Adolescent: A Rare Anomaly.

Accessory fallopian tube is a rare congenital/developmental anomaly, which has important clinical implications and is easily overlooked and missed by the surgeons. The incidence of this anomaly as stated in literature varies from 1.9% to almost 6% in infertile women. We report a case of a 14-year-old girl with dermoid cyst on the left ovary and with an accessory fallopian tube on the right side. The patient underwent laparoscopic dermoid cystectomy along with excision of the accessory fallopian tube. In spite of the presentation's rarity, gynecologists should be aware of such a condition as it has important clinical implications. The presence of an accessory tube predisposes to ectopic pregnancies, torsion, endometriosis, and infertility. Hence, routine careful inspection of the tubes, in any pelvic surgery, is recommended. Whenever encountered, it is advisable to excise these tubes after clear discussion of the implications.
