Abstract:
We report an unusual case of pleomorphic adenoma with multifocal stromal bone formation, occurring in the upper lip of a 44-year-old Japanese woman. Islands of fibrous bone were in direct contact with stromal fibrocytes and parenchymal epithelial cells. A review of the literature revealed that stromal bone formation in pleomorphic adenoma of minor salivary gland origin is exceedingly rare.
