title: Sclerosing polycystic adenosis: a case report.
abstract: About 70 to 80 percent of all salivary gland neoplasms, the majority of which are benign, arise in the parotid gland. Sclerosing Polycystic Adenosis (SPA) is a relatively unknown and newly described entity that is considered to be benign in nature. A 55-year-old patient was treated for SPA in our hospital. The diagnostic work-up consisted of Magnetic Resonance Imaging (MRI), Fine Needle Aspiration Cytology (FNAC) and histological examination. However, in our case, both the cytological appearance, which usually has a high accuracy in discriminating benign from malignant lesions, and the appearance on MR images, mimicked a malignant tumour. This case report illustrates the importance of an adequate histological confirmation of the work-up diagnosis.
