Malignant Mixedmullerian Tumor of Uterus: Rare Case & Rarer Diagnosis

Carcinosarcoma or malignant mixed mullerian tumor (MMMT) of uterus is a rare tumor, representing only 1–2% of all uterine neoplasm. The pre-operative diagnosis of MMMT can be a challenge as no preoperative diagnostic test including endometrial biopsy, CT or MRI has enough sensitivity or specificity. We are reporting one such case of MMMT where endometrial biopsy failed to make a pre-operative diagnosis to highlight the fact that a definitive pre-operative diagnosis can only be made in a small proportion of such cases thus precluding optimal surgery in such cases.
