Primitive neuroectodermal tumor is primarily a central nervous system tumor. These tumors are generally manifest in infancy or early childhood. The following article reports a rare case of primitive neuroectodermal tumor in posterior maxilla in an adult. Treatment for primitive neuroectodermal tumor in extracranial sites in adults is not clearly defined in the literature. This case was treated by combined chemotherapy followed by radiotherapy, which failed to cause regression of the lesion.
