This paper reports a histologically confirmed case of cervical endometriosis in a 33-year-old pregnant patient who presented at 12 weeks with significant post-coital bleeding and a large (6×5 cm), friable mass protruding from the cervical os that completely occluded visualization of much of the cervix. The authors managed initial bleeding with vaginal packing and performed cervical biopsies after consent, applying Monsel solution for hemostasis; subsequent follow-up showed spontaneous regression of the mass after 20 weeks and complete resolution by a 6-week postpartum visit, with successful vaginal delivery and no bleeding from the lesion. The limitation explicitly acknowledged by the case nature of the report is that it cannot establish incidence or management effectiveness beyond this single presentation and outcome. This paper is centrally about endometriosis — specifically cervical endometriosis presenting as bleeding in pregnancy.

Abstract

Introduction: Cervical endometriosis is a very rare site for endometriosis, with a reported incidence of 0.11–2.4%. Case Report: We present a histologically proven case of cervical endometriosis in a 33-year-old pregnant woman who presented with post-coital bleeding during the first trimester of her pregnancy, with subsequent spontaneous regression, and successful vaginal delivery. Conclusion: This case emphasizes the importance of a thorough pelvic examination in patients presenting with bleeding in early pregnancy and biopsy of any lesions as long as it is safe. Cervical endometriosis should be added to the list of differential diagnoses of bleeding in pregnancy after the more common causes have been excluded.
