Intestinal Ewing sarcoma: An unusual presentation in the pediatric age
Abstract Background: Ewing’s Sarcoma (ES) is the second most common type of bone cancer, with an annual incidence of 2.9:100,000. Extraosseous cases represent 15%; however, there are no reported cases of ES located in the intestine in the pediatric population. Case report: We describe the case of a 14-year-old male patient, previously healthy, who started with an anemic syndrome, weight loss, and diaphoresis of 8 weeks of evolution. After visiting a physician, who documented the presence of anemia, the patient was referred to the National Institute of Pediatrics. Physical examination showed grade III-IV systolic murmur, splenomegaly, and pain in the left hemiabdomen with no irradiation. Computed axial tomography showed a mass-dependent on the peritoneum and intestinal loop. A biopsy of the lesion showed intestinal ES. The lesion was completely resected, and the patient was treated with chemotherapy and radiotherapy. Thirty months after diagnosis, the patient has no evidence of tumor activity. Conclusions: Extraosseous presentation of ES in pediatric age is rare. There are no reports of intestinal ES in the Latin American pediatric population, although eight case reports were found in adults. ES is curable by a combination of chemotherapy, radiotherapy, and surgery. The medical literature indicates that the extraosseous presentation should receive the same treatment as the osseous presentation, which can provide a survival rate of up to 70% if there is no evidence of metastasis (which most frequently is observed in the lung).
