Case report and literature review of Ewing's sarcoma in the gastrointestinal tract

Ewing's Sarcoma of the Gastrointestinal Tract—A Case Series

Ewing's sarcoma is a neoplasm of the undifferentiated small round cells, which generally affects the bone and deep soft tissues of children and adolescents. Extraskeletal Ewing's sarcomas are less common than skeletal Ewing's sarcoma with the most common sites being chest wall, retroperitoneal space, lower extremities, paravertebral region, and gluteal region. Primary Ewing's sarcoma of the gastrointestinal tract is rare. The rarity of cases, lack of specific literature, or guidelines for treatment and varying presentations make these cases challenging to diagnose and to treat. In this series, we share our experience from a tertiary cancer care center in South India. By our knowledge, this is the first case series in literature sharing the experience from a single center in treating four cases of gastrointestinal Ewing's sarcoma.

A Rare Case of Gastric Metastasis in Ewing's Sarcoma of the Femur

The stomach is a very unusual site of metastasis. Published reports on metastatic lesion in the stomach is generally limited to single case reports and case series. Gastric metastasis in an Ewing's sarcoma is extremely rare and has been reported in English literature but once to our knowledge. We present a case report of Ewing's sarcoma of the right proximal femur metastasizing to the stomach. A young female treated for Ewing's sarcoma of the femur in 2012 presented with gastric metastasis after four years of disease-free interval. She was treated with irinotecan-based chemotherapy followed by total gastrectomy with esophagojejunal anastomosis and radiation therapy. At one-year follow-up, she was disease free.
