Strangulated bowel obstruction caused by vaginal perforation due to vaginal cancer in a patient with chronic uterine prolapse

A woman in her 90s with chronic uterine prolapse presented with abdominal pain and a vaginal mass. The patient had generalised peritonitis and a strangulated bowel obstruction originating from a perforated posterior vagina. We performed partial intestinal resection and a total hysterectomy, including excision of the perforation of the vaginal site and the adnexa. The patient died on postoperative day 8 due to worsening systemic sepsis. The pathological diagnosis revealed an invasive carcinoma in the perforated area of the vagina. Obstetric factors are the most frequent cause of female genital tract perforation, and chronic uterine prolapse is associated with this condition; however, vaginal cancer has never been reported as a cause of perforation. Therefore, close collaboration in gynaecology should be considered to investigate whether vaginal perforation and uterine prolapse are related to cancer.
