Uterus mullerian adenosarcoma is a very rare malignancy. The clinical and Ultra Sonographic findings are not exclusive and the histomorphologic diagnosis of low-grade adenosarcomas is not straightforward. Herein, we present a young Iranian woman with menometrorrhagia due to exceptional occurrence of uterus Mullerian adenosarcoma.
A 24-year-old woman, with menometrorrhagia was referred. Imaging and pathological findings showed endometrial polyp. She was re-admitted due to abnormal vaginal bleeding after 3 months.  Final diagnosis  based on  histology and immunohistochemical staining was adenosarcoma with sarcomatous overgrowth.
The level of accurate detection and management of low grade uterus mullerian adenosarcoma should be improved. The pathologists and surgeons at major gynecology referral treatment centers are much more likely to be familiar with low grade uterus mullerian adenosarcoma and its clinical awareness.
