Hydrosalpinx due to asymptomatic bilateral tubal pregnancies associated with metaplastic papillary tumor of the fallopian tube.

The patient described in this report had bilateral hydrosalpinx due to pregnancies in both fallopian tubes, treated by laparoscopic resection. Histologically, both fallopian tubes revealed intratubal occlusion by degenerated, partially calcified chorionic tissue. An incidental finding was an intraluminal papillary epithelial tumor in one of the fallopian tubes. The clinical significance and complications of asymptomatic tubal ectopic pregnancy and the pathogenesis and biologic behavior of papillary epithelial tumors of the fallopian tube are briefly discussed.
