Peripheral Calcifying Epithelial Odontogenic Tumor Masquerading as Pyogenic Granuloma of Oral Cavity.

We presented a case of PCOT that initially displayed clinical and histological features similar to pyogenic granuloma. Excisional biopsy and histological examination were performed to determine the definitive diagnosis. Therefore, it is argued that the clinical and incisional biopsy findings represent only alterations in the submitted tissue, which may be deceptive, and the final diagnosis may differ following surgical excision.
