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.

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 primitive neuroectodermal tumor of the kidney

Indian Journal of Pathology and Microbiology, 2018
Renal primitive neuroectodermal tumor (PNET) is a rare entity. It should be differentiated from other primary renal malignancies. The differentiation of the malignant small round cell tumors may be challenging; however, it is essential for better ...

A Case of Ewing’s Sarcoma of the Mediastinum in a 63‐Year‐Old Woman Initially Misdiagnosed as Non‐Small‐Cell Lung Cancer Successfully Treated With Chemotherapy and Radiation With a Durable Response

Case Reports in Oncological Medicine, Volume 2026, Issue 1, 2026.
Mediastinal Ewing’s sarcoma is an exceptionally rare malignancy, with an incidence of approximately 0.3%. Due to the rarity of the tumor and challenges such as limited tissue availability, diagnosis can be difficult. Curative treatment typically requires a multimodal approach, including intensive chemotherapy, surgery, and radiation therapy.

Extraneural Supratentorial Primitive Neuroectodermal Tumor Metastasis: An Adult Case Report

Indian Journal of Neurosurgery, 2017
Extraneural metastases of supratentorial primitive neuroectodermal tumors (PNET) are very rare and have been reported in only sporadic cases. We present a patient with supratentorial PNET metastasizing to the lung, diagnosed 4 months after cerebral ...

Downregulation of Chromosome 19 miRNA Cluster and the Tumor‐Suppressive Role of miR‐517a‐3p in Choriocarcinoma

Cancer Science, Volume 116, Issue 12, Page 3473-3486, December 2025.
Chromosome 19 microRNA cluster was downregulated in choriocarcinoma compared with complete hydatidiform mole. miR‐517a‐3p reduced the proliferation, migration, and invasion abilities of choriocarcinoma cell lines. Downregulation of SRSF1, targeted by miR‐517a‐3p, suppressed the malignant potential of choriocarcinoma cell lines. ABSTRACT Choriocarcinoma

FNA diagnosis of CD99 positive neuroblastoma: A diagnostic dilemma

Journal of Cytology, 2012
Tissue diagnosis of small round cell tumors relies heavily on immunohistochemical staining. Two of the small round cell tumors, namely neuroblastoma and primitive neuroectodermal tumor, have considerable morphologic overlap.
