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.

Pebbled mosaic‐like heterogeneous echogenicity in ovarian immature teratomas and correlation of ultrasound patterns with pathological grades

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
This study characterizes heterogeneous mottled grayscale ultrasound echoes of ovarian immature teratoma as the “pebbled mosaic sign,” noting solid lesions correlate with advanced pathological grades. Preoperative identification of immature tissue informs operative stratification. Abstract Introduction Ovarian immature teratomas (ITs) are rare malignant

Spontaneous Tumor Lysis Syndrome in Primitive Neuroectodermal Tumor [PDF]

Middle East Journal of Cancer, 2019
Tumor lysis syndrome is caused by the massive lysis of tumor cells. It frequently occurs in rapidly proliferating malignancies and less often after solid tumor treatment.

Primitive neuroectodermal tumor of the penile urethra

Indian Journal of Urology, 2021
Primitive neuroectodermal tumor (PNET)/Ewing's sarcoma tumors are a group of highly malignant tumors composed of small, round cells showing neuroectodermal differentiation that commonly affects soft tissue and bone.

AOSNP‐ADAPTR resource level‐based recommendations on practical diagnostic strategies for medulloblastomas and other embryonal tumors

Brain Pathology, EarlyView.
Resource level‐based recommendations on practical diagnostic strategies for medulloblastomas and other CNS embryonal tumors are provided. Abstract WHO CNS5 mandates integrated histo‐molecular classification of medulloblastomas (MBs) and other CNS embryonal tumors. However, advanced molecular diagnostics remain inaccessible in many low‐ and lower‐middle‐

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.

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

Pediatric Blood &Cancer, Volume 73, Issue 11, November 2026.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Exosomes in Cancer: The Biology, Function, Diagnosis, and Therapy

MedComm, Volume 7, Issue 11, November 2026.
Tumor‐derived exosomes and nonmembranous extracellular nanoparticles (exomeres/supermeres) constitute a heterogeneous communication network that drives cancer progression. By shuttling functional biomolecules across tissue‐specific barriers, these nanoparticles orchestrate local microenvironmental remodeling, immune suppression, premetastatic niche ...

Reassessing Bone Marrow Aspirate and Trephine Biopsies in Staging for Paediatric and Young Adult Patients With Ewing Sarcoma and Rhabdomyosarcoma

Pediatric Blood &Cancer, Volume 73, Issue 10, October 2026.
ABSTRACT Ewing sarcoma (ES) and rhabdomyosarcoma (RMS) are aggressive malignancies in children and adolescents where metastases impact prognosis. 18F‐fluoro‐2‐deoxy‐d‐glucose positron emission tomography/computed tomography (FDG‐PET/CT) and bone marrow aspirate and trephine biopsies (BMAT) are used to identify disease involvement.
