Uterine Adenosarcoma: A Case Report and Review of Literature

Uterine adenosarcoma (UA) is an infrequent malignancy which contains the epithelium of benign glands and malignant mesenchymal elements. Low-grade adenosarcoma has a sarcomatous part that is uniformly low grade. Uterine adenosarcoma includes 8% of all uterine sarcomas and less than 0.2% of uterine neoplasms. It is more common in perimenopausal or postmenopausal women. Due to the rarity of uterine adenosarcoma, limited information is available to help guide treatment. A 33-year-old woman, who had one child referred to Imam Hossein Medical Center, Shahid Beheshti University of Medical Sciences, (Tehran, Iran), with a complaint of abnormal uterine bleeding for one year; the sonography reported a polyp in fundal cavity of uterus. The patient underwent hysteroscopy and curettage. The pathology examination revealed uterine adenosarcoma which led to a total hysterectomy and bilateral salpingo-oophorectomy. Abnormal uterine bleeding is the most common symptom of UA. At a young age there is a possibility of misdiagnosis. Hysteroscopy should also be performed if symptomatic or enlarge polypoid lesions are diagnosed preoperatively.
