“…Central PNET such as medulloblastoma originates in the brain and spinal cord, whereas pe ripheral PNETs include adrenal and extra-adrenal neuroblastomas of soft tissues, nerve, and bone. The peripheral Primitive Neuroectodermal Tu mor was first recognized by Arthur Purdy Stout in 1918 as a member of the family of "small roundcell tu mors" which was subsequently designated as PNET [8].…”

Primitive Neuroectodermal Tumor (PNET) is an aggressive round cell malignant tumor which belongs to Ewing's Sarcoma family. Peripheral PNET is rare in head and neck region and even rare in palate with handful of cases reported till date. A case of Peripheral PNET of palate in a 32-year-old female pa tient along with its clinico-pathologic, radiologic and immunohistologic features as well as its management is reported here. We emphasize the need of histopathology and immunohistochemistry (IHC) for early diagnosis of such aggressive tumors to improve the prognosis of patient by providing timely management.

“…The term was first used to describe a group of embryonal tumours located in the central nervous system (cPNET), which were also described as medulloblastomas and medulloepitheliomas. More recently, the PNET concept has been expanded to include histologically similar, but peripherally located, tumours, referred to as peripheral primitive neuroectodermal tumours (pPNETs) (Pereira et al, 2005). The tumours have been described at various sites in children and adults, but only one case has been reported previously in the hand in an adult (Harder et al, 2003).…”

We present a case of a 28 year-old woman who presented with a peripheral primitive neuroectodermal tumour of the right hand involving the fifth metacarpal and little finger. She underwent excision biopsy, then ray amputation of her right little finger. Initial radiological staging did not reveal metastasis but, after recurrence locally at two years and in spite of adjuvant chemotherapy and radiotherapy, the patient died of progressive metastatic disease 4 years later. The current concepts and difficulties in diagnosing these tumours are discussed.

It is seen involving any bone, however it predominately involves central and axial skeleton as well as the diaphysis of long bones.…”

ÖZETPrimitif nöroektodermal tümör, nöroektodermal kaynaklı değişik hücre farklılaşması ile birlikte olan bir neoplazm kategorisini tanımlamak için kullanılan bir terimdir. Bu tü-mörler vücutta birçok yerden kaynak alır. Göğüs duvarı, larinks, karın ve pelvis en sık tutulan bölgeler olup, nadiren baş ve boyun bölgesinde oluşur. Olguların yalnızca %3'ü kafatası ve çeneden köken alır. Bu raporda genç bir erişkinde mandibula sol arka kısmında gelişmiş nadir bir nöroektodermal tümör olgusu sunulmaktadır.Anahtar kelimeler: Nöroektodermal tümörler, primitif, periferik, ağız içi, mandibula ABSTRACTPrimitive neuroectodermal tumor is a term used to describe a category of neoplasms of neuroectodermal origin with variable cell differentiation. These tumors arise in many places throughout the body. The chest wall, larynx, abdomen, and pelvis being the most common primary sites; in rare cases, they occur in the head and neck area. Only 3% of cases have been reported within the skull and jaws. In this report, a rare case of primitive neuroectodermal tumor in the left side posterior mandible in a young adult is described.
