Maxillary Brown Tumor Unveiling Primary Hyperparathyroidism: A Rare Diagnostic Challenge

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Maxillary brown tumors are rare and may mimic malignant or odontogenic lesions, posing a diagnostic challenge. This case highlights that isolated facial swelling may be the first manifestation of primary hyperparathyroidism and underscores the importance of biochemical screening to prevent misdiagnosis and unnecessary surgery.

Epigenetic similarity between adenoid ameloblastoma and dentinogenic ghost cell tumour: DNA methylation analysis in odontogenic tumours

The Journal of Pathology: Clinical Research, Volume 12, Issue 1, January 2026.
Abstract Although adenoid ameloblastoma (AA) has recently been included in the WHO classification as a separate tumour type, its clinical, histological, immunohistochemical, and molecular similarities to dentinogenic ghost cell tumour (DGCT) raise questions about the current classification system. The aim of this study was to investigate the epigenetic

Aggressive Juvenile Trabecular Ossifying Fibroma in a 4‐Year‐Old: Case Report Bringing Diagnostic Challenges and Surgical Management

Case Reports in Dentistry, Volume 2026, Issue 1, 2026.
Juvenile trabecular ossifying fibroma (JTOF) is an uncommon benign fibro‐osseous neoplasm of the craniofacial skeleton that predominantly affects children and may clinically and radiographically resemble other aggressive lesions. We describe the case of a 4‐year‐old boy with a rapidly enlarging, painless maxillary mass.

Le Fort I Osteotomy for Removal of an Extensive Complex Odontoma Involving the Maxillary Sinus: A Case Report and Literature Review

Case Reports in Dentistry, Volume 2026, Issue 1, 2026.
Odontoma is a common odontogenic tumour in the maxillomandibular region, but its occurrence in the maxillary sinus is rare. Small‐ to medium‐sized odontomas can usually be removed without difficulties, depending on their location and proximity to adjacent structures. Nevertheless, access to extensive odontomas may be complicated.
