RESUMO
OBJECTIVE: Ewing sarcoma is a type of neuroectodermal tumors (Ewing family of tumors-EFT) that mostly affect the bone or soft tissue. Primary uterine Ewing sarcoma is extremely rare. CASE REPORT: We report a case of a primary uterine Ewing sarcoma in a 46-year-old patient, treated with total abdominal hysterectomy, and bilateral salpingo-oophorectomy and following adjuvant chemotherapy with 6 cycles of vincristine, doxorubicin, and cyclophosphamide, achieving complete remission for one year. CONCLUSION: Complete resection for EFT is the first choice of treatment, regardless of their origins. Adjuvant chemotherapy or radiotherapy is mandatory if needed. Due to rarity of the disease, this report re-emphasizes the accurate diagnosis and appropriate treatment for these unusual tumor types occurred in female genital organs.

OBJECTIVE: Carcinosarcomas also known as malignant mixed mullerian tumors (MMMTs) contain both carcinomatous and sarcomatous elements. Most MMMTs are arising from female genital tract, including ovaries, uterus and fallopian tubes. Extragenital carcinosarcomas are extremely rare, with an estimation less than 40 cases so far. CASE REPORT: We report two cases of primary peritoneal carcinosarcomas. An 81-year-old woman with pelvic peritoneal carcinosarcoma, heterologous type, was treated with incomplete surgery without further chemotherapy, and died of disease soon. The other one was a 76 year-old woman with abdominal peritoneal carcinosarcoma, homologous type. After optimal debulking surgery and subsequent 6 cycles of combination of paclitaxel and carboplatin chemotherapy, the patient is free of tumor half of year. CONCLUSION: Active therapy, including complete cytoreduction surgery and carboplatin-paclitaxel chemotherapy might offer a chance of disease control for these unusual primary peritoneal carcinosarcomas.
