Uterine adenosarcoma: a case report and review of the literature.

Abstract

Uterine adenosarcoma is a rare gynecological malignancy with no specific symptoms, and the optimal management is still inconclusive. Herein we present a case of uterine adenosarcoma in a 38-year-old woman with a good prognosis and review of literatures. The patient presented with abnormal vaginal bleeding with no special medical history. Sonographic scan revealed a heterogeneous echoic mass in the cavity, indicating a polypus or a submucous myoma. The pathology based on the specimen after the hysteroscopic tumor excision suggested diagnosis of uterine adenosarcoma. Subsequently, the patient received pelvic MRI scan before surgery. MRI identified a patchy lesion at the cervix-lower endometrial cavity with low signal in T1WI and a mixed high T2 signal in T2WI, with no sign of metastasis. Then total abdominal hysterectomy with bilateral salpingo-oopherectomy plus pelvic lymph node dissection was performed and 6 cycles of chemotherapy were administered. The patient remains disease-free on follow-up to date, more than 15 months after chemotherapy.
