Summary Background. The primitive neuroectodermal tumor (TNEP) of the chest wall, or Askin tumor, is a malignant neoplasia classified within the Ewing family of tumours (FSE). This particular type of malignancy of the chest wall is rare and usually appears in the pediatric population. Objective. Describe some characteristics of patients with Askin tumor of the Fundacion Hospital de La Misericordia. Materials and methods. A retrospective analysis of cases treated at a single institution, Fundación Hospital de la Misericordia, in a 16 years period was performed. Results. 8 patients were found, 7 boys, 4 with metastases at the diagnosis, 2 in lungs and 2 in bone, 2 underwent surgery at diagnosis. For the other 6 patients surgical resection was done after chemotherapy. All patients received chemotherapy and 6 received radiotherapy. To date, 5 patients are alive (62 %) with a median follow up of 32 months; 3 of them had metastases at diagnosis. 3 patients died, 2 of which had no metastases in the diagnosis, both relapsed and died of disease progression, the other abandoned treatment at 6 months after diagnosis. Other 2 patients that relapsed received chemotherapy plus autologous transplant, one is alive and the other one died due to disease progression. Conclusion.
