title: Metastatic peripheral primitive neuroectodermal tumor (PNET) masquerading as liver abscess: a case report of liver metastasis in orbital PNET.
abstract: Adult primitive neuroectodermal tumor (PNET) of the orbit is an extremely rare malignant tumor. We report the case of a 37-year-old woman with PNET metastasis of the liver 3 years after treatment of the primary right intraconal orbital PNET with resection and chemoradiation adjuvant therapy. Literature review revealed eight previous cases of orbital PNET, but this is the first case report of liver metastasis arising from orbital PNET.
