Primary Neuroectodermal Tumor of Penis (PNET)—A Case Report

Primary Ewing’s Sarcoma of Penis – A Rare Case Report

“…Primary visceral ES/PNETs are very rarely seen aggressive tumors. We present this case as this is forth case of ES/PNETs with penile localization [1][2][3]. One case of EES metastasizing to penis was also reported [4].…”

Successful penile reconstruction after multimodal therapy in patients with primitive neuroectodermal tumor originating from the penis

“…Sarcoma development is rare, and accounts for less than 5% of penile tumors . To the best of our knowledge, just two patients with primary penile PNET have been reported to date . PNET and EWS have a similar histological spectrum, and share balanced translocation in over 90% of cases (t [11;22][q12;q24]) .…”

“…The penis is an extremely rare site for the primary PNET, with two cases being reported to date. 2,3 We present a case of PNET originating from the penis in a patient who underwent penile reconstruction after multimodal therapy and has maintained a long-term no recurrence status.…”

Peripheral primitive neuroectodermal tumour – a rare cause of a popliteal fossa mass: A case report and review of the literature

“…pPNETs pPNETs are an extremely rare cause of a popliteal mass. Believed to originate from migrating embryonic cells of the neural crest (3), pPNETs are most commonly found in the chest wall and axial soft tissues (4,5), although they have been diagnosed in other areas including bone, extra-axial soft tissue and visceral tissues (6)(7)(8)(9)(10)(11). Belonging to a family of 'small round-cell tumours', they are most frequently observed in children and young adults, but can occur at any age (12,13).…”
