Definition / general
  • High stage with pelvic extension or positive peritoneal cytology
  • To call primary in fallopian tube, should arise from mucosa (endosalpinx), have tubal histologic pattern, involve the lumen, uterus and ovaries must be normal or have foci of malignancy that resemble metastases or independent primaries; if tubal wall is involved, should detect a transition between benign and malignant tubal epithelium
  • 5 year survival: stage 1 - 77%, stage 3 - 20%; usually recur intra-abdominally
  • Associated with BRCA1 and BRCA2 mutations; for patients with known mutation or family history of breast or ovarian cancer, should submit entire fallopian tube and ovary for microscopic examination (Am J Surg Pathol 2002;26:171, Am J Surg Pathol 2001;25:1283)
  • 50% serous, 25% endometrioid, 20% transitional or undifferentiated
  • Symptoms: vaginal bleeding or discharge (2/3), pain, adnexal mass (triad in 50%); endometrial smear positive in 10%
Gross description
  • Enlarged tube, with solid or papillary tumor filling the lumen
  • Tumors occasionally are primary in the fimbriae
  • 80 - 97% unilateral; hemorrhage, necrosis and cysts common
