Sclerosing Polycystic Adenosis(SPA) of the Submandibular Gland Mimicking Malignant Salivary Gland Tumor : A Case Report

Sclerosing polycystic adenosis(SPA) is a pathology of salivary gland which occurs infrequently. It has a contro-versial etiology. It is a recently described and extremely rare disease entity. Its reactive, sclerosing and inflam-matory process is similar to fibrocystic changes and adenosis tumor of breast. Most cases has been reported to be occurred within major salivary glands. This disease is frequently confused with other salivary gland carcinomas, especially because of its histomorphological similarity. Here, we report a case of SPA within the submandibular gland in a 62-year-old woman.
