Non-puerperal uterine inversion is an extremely rare entity, which many gynaecologists would never come across in their lifetime. Diagnosis can be difficult. Our patient was a 91-year-old lady who presented with profuse vaginal bleeding. Hysteroscopy was unsuccessful as the cervix was completely replaced by a friable growth. A total abdominal hysterectomy and bilateral salpingo-oophorectomy was planned as a palliative measure to stop bleeding. Uterine inversion was suspected for the first time at laparotomy and confirmed after dissecting the hysterectomy specimen, which revealed both tubes and ovaries lying inside the inverted uterus. Histology showed a malignant mixed mullerian tumour of the uterus.
