A primitive neuroectodermal tumor (PENT) belongs to the category of a Ewing sarcoma. A PENT of the uterus is rare and has been known to be very aggressive by nature. Owing to the rarity of the tumor, there is no optimal treatment at present. In many cases, after hysterectomy, chemotherapy or radiation therapy has been performed. However, an effective chemotherapy regimen was unclear. In the soft tissue sarcoma area, the chemotherapy approach has recently greatly improved. Vincristine, doxorubicin, cyclophosphamide, ifosfamide and etoposide (VDC-IE) therapy has improved the survival rate of patients with Ewing sarcoma/PENT. Thus, VDC-IE therapy may be used for a uterine PENT. Here, we report a case of a uterine PENT in a premenopausal woman successfully treated with multimodality treatment including VDC-IE therapy and discuss the optimal chemotherapy for a uterine PENT through a literature review.

Desmoplastic small round cell tumor is a very rare soft tissue sarcoma with a bleak prognosis and short patient survival. The most common occurrence is in 20-30-year-old men. Our study presents the case report of a 40-year-old patient who was diagnosed with this sarcoma.

Article Synopsis
- Patients with serious forms of Ewing sarcoma (ES) and rhabdomyosarcoma (RMS) may benefit from a treatment called high-dose chemotherapy with stem cell transplant, but it's still unclear how much it helps and it can cause serious side effects.
- A review of many studies found that for some ES patients, this treatment can improve their chances of living longer compared to standard chemotherapy, especially if they receive it after a specific type of chemotherapy.
- However, for RMS patients and those with advanced ES, the evidence doesn't show a clear benefit, and more research is needed to understand the best treatment options.

Sarcoma with genetic alteration is an exceptionally rare and emerging subtype of sarcoma. It is categorized into two types: -related gene fusions such as sarcomas and other -rearranged sarcoma and sarcomas with internal tandem duplication of genes such as infantile undifferentiated round cell sarcomas and primitive myxoid mesenchymal tumors of infancy. sarcomas predominantly arise in bone rather than soft tissue and exhibit a higher occurrence in children and adolescent males, whereas sarcomas with internal tandem duplication show a wider age range but usually arise in the first year of life.

Article Synopsis
- A study was conducted on twelve Asian patients with various types of sarcoma who received interval-compressed chemotherapy, alternating between two specific drug regimens (VDC and IE), with support from filgrastim and carboplatin for certain cases.
- The treatment included a total of 129 cycles, with a median interval of 19 days between cycles, and showed that patients had manageable side effects, like neutropenia and low platelet counts, with a notable percentage experiencing fever.
- Out of the nine patients with measurable tumors, seven showed a positive response to the treatment, indicating that this chemotherapy approach is feasible for Asian children and young adults with sarcoma.

Purpose: Extraskeletal Ewing sarcoma (EES), is a rare soft tissue sarcoma. Treatment for EES commonly involves chemotherapy and surgical resection (ST) or less commonly combined chemotherapy, surgery, and radiotherapy (ST + RT). The purpose of the current study was to evaluate our institutional experience treating EES.
