Core Tip

Core Tip: Ewing sarcoma (ES) is a rare and highly malignant small round cell tumor. Extraskeletal ES is more common in the paravertebral region, extremities, and retroperitoneum and very rarely occurs in the stomach. Due to its rarity, there are few studies on its clinicopathological characteristics and diagnostic protocols. It is an aggressive tumor with poor prognosis, and therefore, early diagnosis and timely intervention are vital for a good prognosis. Herein, we report on a case of primary gastric ES which was timely resected surgically. This was followed by chemotherapy, which was comprised of alternating vincristine–doxorubicin, cyclophosphamide, and ifosfamide–etoposide every 3 wk. Ultimately, the patient was tumor-free and achieved an excellent prognosis.
