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.

SUFU Loss‐of‐Function Heterozygous Variants Cause a Distinct Neurodevelopmental Delay With Simultaneous Effects on Brain Size

Human Mutation, Volume 2026, Issue 1, 2026.
Heterozygous loss‐of‐function variants in SUFU are associated with Gorlin syndrome (MIM:620343) and tumor predisposition, while biallelic missense variants underlie recessive Joubert syndrome (JS; MIM:617757). Interestingly, emerging evidence suggests that SUFU haploinsufficiency also contributes to neurodevelopmental disorders (NDDs).

Central Odontogenic Fibroma: A Rare Benign Tumor With Potentially Life‐Threatening Implications

Clinical Case Reports, Volume 13, Issue 8, August 2025.
ABSTRACT Central odontogenic fibroma (COF) is a rare benign tumor originating from periodontal tissues. Although it typically grows slowly and remains asymptomatic, COF can cause significant complications when neglected, including displacement of teeth, bone destruction, and even life‐threatening airway obstruction.
