Diffusion, Perfusion, and Histopathologic Characteristics of Desmoplastic Infantile Ganglioglioma. [PDF]

, 2016
We present a case series of a rare tumor, the desmoplastic infantile ganglioglioma (DIG) with MRI diffusion and perfusion imaging quantification as well as histopathologic characterization. Four cases with pathologically-proven DIG had diffusion weighted

Molecular pathology of testicular germ cell tumours: an update for practicing pathologists

Histopathology, Volume 88, Issue 1, Page 214-229, January 2026.
Molecular testing for isochromosome 12p is usually only necessary in difficult cases that encompass metastases or recurrent diseases including somatic‐type malignancies. So far, no breaking progress has been made in the field of targeted therapy as TGCTs only rarely show targetable molecular alterations.

Haplótipos de diferentes SNPs no interior do gene EWS em indivíduos afetados e não-afetados pelo sarcoma de Ewing [PDF]

, 2012
Ewing’s sarcoma was first described by James Ewing in 1921 and it is the second most common bone tumor in children and young adults. Both chromosomal breakage and translocation occur in this sarcoma.

Imatinib inhibits proliferation of Ewing tumor cells mediated by the stem cell factor/KIT receptor pathway, and sensitizes cells to vincristine and doxorubicin-induced apoptosis [PDF]

, 2004
Purpose and Experimental Design: The stem cell factor/ KIT receptor loop may represent a novel target for molecular- based therapies of Ewing tumor. We analyzed the in vitro impact of KIT blockade by imatinib in Ewing tumor cell lines.

A case of primary mediastinal Ewing's sarcoma / primitive neuroectodermal tumor presenting with initial compression of superior vena cava

Annals of Thoracic Medicine, 2013
Ewing's sarcomas and peripheral primitive neuroectodermal tumors (ES/PNETs) are high grade malignant neoplasms. These malignancies are characterized by a chromosome 22 rearrangement, arise from bone or soft tissue, predominantly affect children and young

Development of the neurohypophysis: A major neuroendocrine interface

Journal of Neuroendocrinology, Volume 38, Issue 1, January 2026.
Abstract The neurohypophysis is a major central neuroendocrine interface regulating reproductive functions and water homeostasis. Distinct neurovascular cell types interact via evolutionarily conserved signaling molecules in the developing neurohypophysis, providing a model system for studying principles in neuroendocrine interface morphogenesis.

Primary renal primitive neuroectodermal tumor.

Journal of postgraduate medicine, 2015
Primitive Neuroectodermal Tumor of the kidney is a rare entity. Very few cases of primary renal PNET have been reported to date. Most literature about rPNET is isolated case reports. We report a case of rPNET in a 39-year-old male with a pre-operative diagnosis of renal cell carcinoma with renal vein thrombosis.

Primary Ewing′s Sarcoma of the Sinonasal Region: A Rare Clinical Encounter

Case Reports in Pathology, Volume 2026, Issue 1, 2026.
Ewing′s sarcoma (EWS) is a highly aggressive tumor of neuroectodermal origin, rarely occurring in the sinonasal tract, particularly in adults. We report a 27‐year‐old male with long‐standing nasal obstruction, initially misdiagnosed as nasal chondromesenchymal hamartoma. Surgical excision revealed a destructive, vascular sinonasal mass.
