Abstract
Primitive neuroectodermal tumor (PNET) of the lung is rare in adults, and
treatment options vary. We herein describe the disease course and follow-up of
PNET in an adult. A 27-year-old man was admitted to our hospital because of
cough and headache, and whole-exome sequencing revealed positive expression of
the EWSR1-FLI1 fusion gene and amplification of the
APC gene. Although the patient received multidisciplinary
treatment including chemotherapy regimens of etoposide plus cisplatin; focal
radiotherapy focusing on the cerebrum, lung, and kidneys; and a subsequent
palliative gastrointestinal operation, he eventually died of multiple organ
functional failure. His overall survival period was 18 months, and his
progression-free survival period was 4 months. During the treatment, the patient
showed remarkable sensitivity to radiotherapy. In conclusion, PNET of the lung
in adult patients is extremely rare, and the prognosis is very poor. Involvement
of a multidisciplinary team in the development of personalized therapeutic
strategies is essential. This patient with APC gene
amplification showed excellent sensitivity to radiotherapy for intrapulmonary
and intracranial lesions, suggesting that APC gene
amplification may be related to radiotherapy sensitivity. However, further
clinical research is needed.

Front Surg 2021; 8:667467.

Abstract
Peripheral primitive neuroendodermal tumors (PNETs) and Ewing's sarcoma belong to the Ewing family of tumors and are small round-cell malignancies originating from spinal cord cells. These tumors account for 5% of all small round-cell malignant neoplasms. PNETs that arise from the lung parenchyma without pleural or chest wall involvement are very rare. We report a case of an adult female with a large pulmonary PNET who had given birth just 1 month prior to the diagnosis. She had cough and expectoration for 6 months, and the preoperative examination showed no metastases. Thus, we performed radical pneumonectomy and lymph node dissection. The patient recovered well without surgical complications and was discharged 7 days after the surgery. Postoperative pathology confirmed that the tumor was a small round-cell malignancy, and the tumor cells were positive for CD99, Friend leukemia virus integration 1 (FLI-1), and neuron-specific enolase (NSE), which was consistent with the diagnosis of a PNET. For primary large pulmonary PNETs, radical pneumonectomy may be a safe surgical method, worthy of further application in clinical practice.

Abstract
Primitive neuroectodermal tumors (PNETs) arising from the lung without thoracic wall involvement are extremely rare and particularly aggressive neoplasms. Herein, we present the case of a 41-year-old woman with pulmonary PNET diagnosed following histopathological, immunohistochemical, and molecular pathological examination of a surgical biopsy specimen. The case report is accompanied by a literature review of primary pulmonary PNETs.
