Primitive chest wall neuroectodermal tumor in a pediatric patient.

A 13-year-old boy with a primitive neuroectodermal tumor of the chest wall is presented. After four cycles of chemotherapy, a computed tomography scan of his chest showed a larger mass invading the left upper lobe of the lung. He underwent resection of the left chest wall from the left fourth to sixth ribs, including the tumor, combined with left upper lobectomy and lymph node dissection. A diagnosis of primitive neuroectodermal tumor was confirmed histopathologically and immunohistochemically. After surgery, four cycles of chemotherapy with ifosfamide and etoposide were given. One year after treatment, the patient is currently doing well without evidence of recurrence.
