Primitive Neuroectodermal Tumor of the Gallbladder

Archives of Pathology & Laboratory Medicine, 2004
Abstract Ewing sarcoma/primitive neuroectodermal tumor (ES/ PNET) most commonly occurs in the soft tissues of the extremities and the paravertebral areas. To our knowledge, no case of PNET has been reported in the gallbladder to date. We report a case of PNET of the gallbladder occurring in a 53-year-old woman.

Diffuse intrinsic pontine tumors: A study of Primitive Neuroectodermal Tumors versus the more common Diffuse Intrinsic Pontine Gliomas

Journal of Neurosurgery: Pediatrics, 2012
Objective The diagnosis of diffuse pontine tumors has largely been made by Magnetic Resonance Imaging since the early 1990s. Tumors considered “typical” have, as a rule, not been biopsied but considered diffuse intrinsic pontine gliomas (DIPGs).

Factors Affecting Surgical Outcomes Following Rotationplasty in Paediatric Sarcoma: A Literature Review

ANZ Journal of Surgery, EarlyView.
Rotationplasty is a durable limb‐salvage option for paediatric lower‐limb sarcoma. Across 58 studies and 1,217 patients, long‐term functional, psychosocial, and quality‐of‐life outcomes were favourable, often surpassing amputation and endoprosthetic reconstruction.

Primitive neuroectodermal tumor of the ovary

Saudi Medical Journal, 2008
A 31-year-old woman presented to King Abdulaziz University Hospital complaining of an abdominal pain and a rapid increase in abdominal girth. An ultrasound and MRI, revealed a huge cystic ovarian mass without ascites. Ovarian tumor markers were all within normal range. Exploratory laparotomy showed huge right ovarian mass with omental mass.

Pattern‐based interpretation of SOX2 expression in ovarian teratomas: avoiding diagnostic pitfalls in the distinction between immature and mature neuroectodermal elements

Histopathology, EarlyView.
Ovarian immature teratoma grading may be confounded by mature neuroectodermal mimics. SOX2 labelled immature neuroepithelium but also mature ependymal and glial tissue, while SALL4 was negative in mature mimics and variably expressed in immature neuroepithelium.
