The Role of Vimentin 3 in Ameloblastomas: A Novel Tumor Biomarker

Oral Diseases, EarlyView.
ABSTRACT Introduction Ameloblastoma (ABL), a common odontogenic tumor in the maxillofacial region, presents primarily as unicystic (U‐ABL) and conventional (C‐ABL) variants. Despite shared epithelial features, their distinct biological behaviors may stem from interactions between connective tissue and epithelial cells.

Proposal for a New Classification of Rare Cancers Adopting Updated Histological Tumor Types

Pathology International, EarlyView.
We propose a new rare cancer classification system using the updated International Classification of Diseases for Oncology 3.2 coding system and the World Health Organization Classification of Tumors 5th edition. This list could serve as a diagnostic classifier to reliably distinguish various rare cancers for clinical applications.
