a rare case of mullerian adenosarcoma of uterus in a 14-year-old girl

background: mullerian adenosarcoma, a rare tumor, is composed of mixed mesenchymal and epithelial elements. the epithelial component is typically benign and admixed with malignant sarcomatous stroma. this tumor can be distinguished in approximately 8% of all uterus sarcomas and commonly originates in the endometrium as a growing polypoid mass in the uterine cavity. all age groups are affected but the average age of uterine adenosarcoma is about 58. case report: we aim to introduce a 14-year-old case of uterine adenosarcoma as a rare occurrence, presenting with menometrorrhagia and formation of uterine fragile polypoid mass which extends into vagina. total abdominal hysterectomy (tah) and staging were performed. she had been clinically disease-free in a 40-month post operation follow-up. distant metastasis is a very rare phenomenon, albeit the necessity of long-term follow-up seems necessary .conclusion: data accumulation of individual cases with such unusual neoplasm is essential for further experience provision.
