Malignant Lesions of the Fallopian Tube and Broad Ligament
Updated: Oct 9, 2008
Introduction
Background
In 1847, Renaud first described fallopian tube malignancy. In 1888, Orthmann submitted the first genuine case report.1
The broad ligament is a double fold of peritoneum, which is formed by the reflection of the peritoneum off the pelvic floor and the lateral pelvic wall. Most tumors are benign cysts, but malignant tumors are categorized as either primary or secondary.
Primary malignancies of the broad ligament include those of müllerian origin (ie, serous carcinoma, papillary carcinoma, cystadenocarcinoma, endometrioid carcinoma, clear cell carcinoma), urothelium transitional cell carcinoma, mesenchymal sarcoma or histiocytoma, and pheochromocytoma.
Secondary malignancies of the broad ligament include metastatic cancers from endometrial, cervical, and ovarian carcinoma.
A primary malignancy is diagnosed based on its location within or on the surface of the broad ligament and by virtue of the complete separation of the tumor from the uterus and ovaries.

Pathophysiology
Fallopian tube malignancy usually starts as a dysplasia or carcinoma in situ. Typically, transition to adenocarcinoma is observed.
The etiology of malignancies of the broad ligament is unknown, although they are associated with endometriosis.
Frequency
United States
Fallopian tube carcinomas comprise 1% of all gynecologic cancers. The average annual incidence is 3.6 cases per million women.
Mortality/Morbidity
On average, the 5-year survival rate is 51%; the rate for stage I disease is 65%, stage II disease is 50-60%, and stage III and stage IV disease is 10-20%.
Age
Incidence increases with age but peaks at 60-66 years.
Clinical
History
- Malignant lesions of the fallopian tube
- Patients may present with pelvic pain, a pelvic mass, postmenopausal bleeding, and serosanguineous vaginal discharge.
- The classic description of hydrops tubae profluens, which is characterized by colicky lower abdominal pain relieved by a profuse, serous, watery, yellow, intermittent, vaginal discharge, usually is not found.
- Malignant lesions of the broad ligament
- A clinical history of vague abdominal pain may be present. Upon examination or with abdominal exploration, an adnexal mass is found.
- Rarely, it can manifest as an acute abdominal emergency, simulating appendicitis.
Physical
- Physical examination findings are not specific; a pelvic mass usually is present, with or without ascites.
- Diagnostic criteria include the following:
- Grossly, the main tumor should be in the fallopian tube.
- Histologically, the tubal mucosa should be involved, with a papillary pattern.
- The tubal wall, if involved, and a transition from benign to malignant tubal epithelium should be identified.
- The lesion is a more advanced stage of tubal tumor than the other tumors.
Causes
- The exact etiology is unknown.
- Infertility and chronic salpingitis were believed to lead to an increase in incidence, but this theory has not been proven. However, malignancy has been associated with tuberculous salpingitis.
- Similar to ovarian malignancy, a BRCA germline mutation and TP53 mutation are associated with fallopian tube malignancy.
