ABSTRACT
Sclerosing polycystic adenosis (SPA) of the salivary glands is a rare entity analogous to fibrocystic disease of the breast. Less than 50 cases of SPA have been published in the literature. We report the first Korean case of SPA of the right parotid gland. A 34-year-old man presented with a slowly growing right parotid mass. Computed tomography showed a relatively well-demarcated, heterogeneously enhancing mass with multiple small calcifications. Fine needle aspiration showed cohesive sheets of epithelial cells with granular oncocytic cytoplasm and scattered lymphocytes. The parotidectomy specimen showed a 3 cm-sized solid nodular lesion with small cysts. Microscopically, the lesion was an unencapsulated mass of sclerotic fibrous tissue with cystic ducts, multiple calcifications, and lymphoplasma cell infiltration. Sclerosing adenosis and cystic ducts with frequent apocrine-like cells were noted. Familiarity with the cytologic and histological features of SPA is very important making the correct diagnosis.
