RATIONALE: Central nervous system primitive neuroectodermal tumors (CNS PNETs) mostly occur in children and present as cerebellar medulloblastoma. A few cases of PNETs occur in the cerebral hemisphere. The presence of a PNET in ventricles is extremely rare. The prognosis of CNS PNET is extremely poor, and the 5-year survival rate does not exceed 35%. In the present study, we describe the first case of a PNET in the ventricles with good prognosis. PATIENT CONCERNS: The case of a 36-year-old man is reported, who presented with a progressively worsening headache for 2 months...

Sinonasal tumors with neuroendocrine differentiation form a group of rare heterogeneous neoplasms of neuroectodermal and epithelial origin, consisting of olfactory neuroblastomas and neuroendocrine carcinomas. Because the natural history and biological behavior of this group of tumors vary, the morphological diagnosis coupled with grading/staging is important for prognostication, and the approach to treatment and rehabilitation is multidisciplinary. The identification of molecular abnormalities underlying these tumors is critical to the development of specific targeted therapies and the design of clinical trials...

There is an urgent need for advances in the treatment of Ewing sarcoma (EWS), an aggressive childhood tumor with possible neuroectodermal origin. Inhibition of histone deacetylases (HDAC) can revert aberrant epigenetic states and reduce growth in different experimental cancer types. Here, we investigated whether the potent HDAC inhibitor, sodium butyrate (NaB), has the ability to reprogram EWS cells towards a more differentiated state and affect their growth and survival. Exposure of two EWS cell lines to NaB resulted in rapid and potent inhibition of HDAC activity (1 h, IC50 1...

REVIEW
Qing Li, Yong Liu, Yang Yu
RATIONALE: Peripheral primitive neuroectodermal tumor (PNET) is a kind of small round cell tumor derived from primitive neuroectodermal tumor. PATIENT CONCERNS: PNET is a highly malignant tumor that is subordinated to Ewing sarcoma. It occurs predominantly in soft tissue and bone and rarely in the bronchi and lung. Traditional surgery, radiotherapy, and chemotherapy are used for the treatment of PNET, but are usually ineffective. DIAGNOSES: There was a rare case of a 17 year-old man diagnoses with primary pulmonary PNET...

Primary leptomeningeal primitive neuroectodermal tumors (PNETs) are extremely rare childhood central nervous system malignancies harboring a very poor prognosis. There is no consensus treatment for these tumors to date. We report a case of a 10-year-old male who presented with mental status change, hydrocephalus, intracranial and spinal diffuse leptomeningeal enhancement without a primary mass upon cranial imaging and a negative initial biopsy until five months into his presentation. He responded significantly well to initial chemotherapy and radiotherapy...

Strumal carcinoid represents a rare form of ovarian teratoma, consisting of both thyroid tissue and carcinoid structures. The carcinoid component is a well-differentiated neuroendocrine tumor with excellent prognosis. Strumal carcinoid tumors are commonly found in peri-menopausal women who are not usually interested in preserving their fertility and who are thus open to radical surgical treatment. In this report, we present a 24-year-old, nulliparous patient with strumal carcinoid, confirmed by histopathology and a large panel of immunohistochemistry (IHC) markers, who wished to preserve her fertility...

Context: Tumors of the central nervous system (CNS) constitute the second most common pediatric cancers. Unlike leukemia, management of CNS tumors requires a good multidisciplinary team. Higher rates of treatment abandonment are documented in view of complexity of the treatment with long duration, involving neurosurgery, radiation, chemotherapy, and high cost of treatment. Morbidity associated with CNS tumors may be significant in terms of physical deficits as well as neuropsychological and neuroendocrine sequelae...

PURPOSE OF REVIEW: This article describes the most common pediatric brain tumors and highlights recent developments in their diagnosis and treatment strategies. RECENT FINDINGS: We are in the midst of a molecular era for pediatric brain tumors. Genetic and epigenetic profiling of tumors has impacted their diagnosis, allowing for the subgrouping of heterogeneous tumor groups and leading to the complete renaming of some tumor types. These advances are reflected in the new 2016 World Health Organization classification...

Sarcomas represent less than 1% of all malignant tumors found in the thyroid. Of these, primary extraosseoussarcoma has been reported only a few times in the past decade. We present the case of a 34-year-old male who had a fast-growing hard mass in the lower left neck. FNA was inconclusive. Core needle biopsy revealed the diagnosis of an Ewing sarcoma/primitive neuroectodermal tumor. Mutation of EWSR1 was confirmed using the FISH method. Following treatment by neoadjuvant chemotherapy, we observed clinical, radiological, and finally histopathological remission...

Lungs are one of most metastatic areas for primitive neuroectodermal tumor (PNET), however primary pulmonary PNET is extremely rare. Here we present a case of a 58-year-old male patient with a tumor in the right lung that originated from the lung but not from chest wall. Patient was diagnosed with PNET following histological and immunohistochemical examination of CT-guided percutaneous tru-cut needle biopsy and no distant metastasis were detected in PET-CT scan. As advised recently in published literature, surgical resection following neoadjuvant chemotherapy protocol is preferred in the treatment of our patient as it has better success of complete resection leading to higher 5-year survival rates...
