Uterine Inversion as a Result of a Large Prolapsed Carcinosarcoma of the Uterus.

BACKGROUND: Uterine inversion is most commonly seen in labour and delivery. However, it can be associated with uterine tumours, including gynaecologic malignancy. CASE: In a 66-year-old woman, uterine inversion identified at laparotomy that was found to be associated with uterine carcinosarcoma (malignant mixed mesodermal tumour) represents an unusual presentation. Surgical approach necessitated a vertical hysterotomy to amputate and deliver the uterine tumour. CONCLUSION: Uterine inversion in gynaecologic oncology may be associated with sarcoma or malignant mixed mesodermal tumour. This can represent a diagnostic and surgical challenge and should be considered.
