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

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 ...

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.

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.

Evidence of a dual histogenetic pathway of sacrococcygeal teratomas [PDF]

, 2016
Aims Sacrococcygeal teratomas are rare tumours that occur most frequently in neonates, although adult cases also occur. The molecular pathogenesis of these tumours and their long-term prognosis is uncertain.

Association Between Sensorineural Hearing Loss and Neurocognitive Performance in Survivors of Childhood Cancer: A Systematic Review and Meta‐Analysis

Cancer Medicine, Volume 14, Issue 22, November 2025.
This systematic review and meta‐analysis found that childhood cancer survivors with severe sensorineural hearing loss (s‐SNHL) had significantly lower scores in various neurocognitive domains, including IQ, memory, and processing speed, compared to survivors without s‐SNHL.
