“Intrabony” palatal pleomorphic adenoma

Abstract

Pleomorphic adenoma (PA) is the most common neoplasm of the large salivary glands. It derives its name from the architectural pleomorphism seen by light microscopy. It is also known as the mixed tumor salivary type, which describes its pleomorphic appearance as opposed to its dual origin from epithelial and myoepithelial elements. We present a case of an adult who presented with a palatal swelling, which computed tomography (CT) scan showed to be “intrabony” but after considering other planes of the CT scan It was finally considered to be an intrabony extension of the palatal PA. The mass was successfully removed and the residual palatal defect left to granulate. Following 2 years of patient follow-up, there was no recurrence but the presence of a oronasal defect about 1 cm in diameter in the palate.
