Abstract

Sclerosing polycystic adenoma (SPA) is a rare salivary gland tumor with about 100 cases reported in the literature. We describe a case of SPA in the parotid gland and review the diagnostic tools used for identifying SPA. A 24-year-old male with a two-year history of right-sided face mass, initially thought to be pleomorphic adenoma of the parotid gland after fine needle aspiration (FNA). Following superficial parotidectomy, histologic features were consistent with SPA. This case illustrates the challenge of pre-operative assessment for SPA. Recent study has suggested SPA is a neoplasm and definitive treatment is surgical excision.
