Ewing Sarcoma/Primitive neuroectodermal tumor (ESIPNET) is the second most common primary malignant bone tumor, following osteosarcoma, in children and adolescents, most often arising in long bones. Primary pulmonary ES/PNET is very rare and is seen only as case reports in the literature. Here, we report on a 24-year-old mart who had bilateral multiple pulmonary masses and nodules on a chest X-ray By transthoracic biopsy he was diagnosed with ES/PNET. Since no other primary focus was determined in his Positron Emission Tomography Computed Tomography and total body bone scan, the patient was accepted as primary pulmonary ES/PNET. To our knowledge only twenty cases have been described in the English literature and of them only two had intrapulmonary multiple metastases. We present this case because he will be the third reported ES1PNET case which has been seen with bilateral multiple pulmonary metastases.
