The study aims to investigate the expression patterns of bone resorption regulators (RANK, RANKL, and OPG) in recurrent ameloblastoma (RA) to understand their influence on tumor behavior.
Fifteen RA cases were analyzed using immunohistochemistry, revealing a complex distribution of these proteins, with strong RANK expression in the tumor epithelium, low RANKL levels, and higher OPG presence in the neoplastic epithelium.
The findings indicate a unique RANK(+)/RANKL(low)/OPG(+) profile in RA, implying altered bone metabolism with reduced resorptive activity in these tumors.
