Uterine adenosarcoma is usually a low-grade neoplasm with a mixed benign epithelial component and malignant stroma, commonly found in postmenopausal women. In the presence of sarcomatous overgrowth, it has been shown to have poor prognosis. Uterine adenosarcoma with sarcomatous overgrowth and rhabdoid features is extremely rare. We report here a case of a 28-year-old female who was found to have adenosarcoma with sarcomatous overgrowth with extensive rhabdoid features. The tumor had metastasized to the pelvis, omentum, iliac, and obturator lymph nodes. She was lost to follow-up for 10 months, after which she presented with recurrent tumor at the hysterectomy site. She was started on palliative chemoradiotherapy, on which she progressed but later experienced drug toxicity, became cachectic, and was unwilling to continue chemotherapy. There are a few cases of adenosarcoma with sarcomatous overgrowth reported in young women and only two cases with rhabdoid features. Based on this report, adenosarcoma with sarcomatous overgrowth and rhabdoid features appears to be an extremely aggressive tumor with poor prognosis.
