Benign tumor of fallopian tubes

Benign tumors of the fallopian tubes are rare non-cancerous growths that develop within or on the fallopian tubes, the paired structures that connect the ovaries to the uterus. These tumors encompass a variety of histological types, including leiomyomas (the most common benign fallopian tube tumor, arising from smooth muscle), adenomatoid tumors (arising from mesothelial cells), cystadenomas, lipomas, hemangiomas, and benign teratomas. Because of their rarity and often small size, they are frequently discovered incidentally during pelvic surgery, imaging studies performed for other indications, or pathological examination of surgical specimens. Many patients with benign fallopian tube tumors are asymptomatic. When symptoms do occur, they may include pelvic or lower abdominal pain, a palpable adnexal mass, menstrual irregularities, or, in some cases, infertility due to tubal obstruction. Occasionally, torsion of the tumor or the fallopian tube itself can cause acute pelvic pain requiring emergency intervention. These tumors primarily affect the female reproductive system. Diagnosis is often challenging preoperatively and may involve pelvic ultrasound, MRI, or CT imaging, though definitive diagnosis typically requires histopathological examination of the excised tissue. Treatment generally involves surgical removal, which may range from a conservative tubal-sparing procedure (such as enucleation of the tumor) to salpingectomy (removal of the affected fallopian tube), depending on the tumor size, location, and the patient's reproductive wishes. The prognosis following surgical excision is excellent, with very low recurrence rates. No systemic medical therapy is typically required.
