Abstract
Sclerosing polycystic adenosis (SPA) is a rare benign salivary gland lesion that resembles both benign and malignant tumors, complicating diagnosis. We present the case of a 44-year-old woman with progressive right lateral facial swelling. MRI suggested a pleomorphic adenoma and initial parotidectomy was followed by total excision based on frozen section results. Final histopathological analysis confirmed SPA, with characteristic abnormal glandular architecture in a sclerotic stroma and absence of malignant features. Complete surgical excision was curative. This case underscores the importance of considering SPA in the differential diagnosis of parotid masses.
