ABSTRACT: Serous
tubal intraepithelial carcinoma is a putative precursor of high-grade serous
carcinoma, which is the most common histological type of ovarian or pelvic
peritoneal cancer. Serous tubal intraepithelial carcinoma is commonly found in
patients with breast cancer susceptibility gene mutations who undergo
risk-reducing salpingo-oophorectomy. Incidental serous tubal intraepithelial carcinoma found by a non-prophylactic
surgery is rare. A 33-year-old woman referred to our hospital for a
diagnosis of ectopic pregnancy. She underwent a laparoscopic right
salpingectomy. Pathologically, ectopic pregnancy in the ampulla of the right
fallopian tube was confirmed and serous tubal intraepithelial carcinoma was
observed in the fallopian tube. Subsequently, she underwent a laparoscopic
hysterectomy, bilateral oophorectomy, and left salpingectomy as additional
treatment. She has experienced no recurrence thus far for 37 months since the
surgery.
