Sclerosing Polycystic Adenosis of Salivary Gland: A Newly Described Tumor with Review of Literature

Background: Sclerosing polycystic adenosis (SPA) is a rare, recently described, tumorous condition of the major or minor salivary glands that on gross and microscopic evaluation mimics an invasive carcinoma. The histology quite similar to seen in fibrocystic disease, sclerosing tumors breast. It also resembles more diffuse bilaterally occurring dysgenetic disease (PDD) parotid gland. To best our knowledge, only 68 cases have been described so far. Case Report: Here we describe case SPA involving gland 58 year old male. At first instance, possibility low grade mucoepidermoid carcinoma was considered. However, histologically, it well circumscribed lobulated lesion composed acini ducts sclerotic stroma. Immuno-staining for SMA p63 highlighted myoepithelial cells around which exhibited extensive metaplastic changes. Conclusion: Awareness essential avoid misdiagnosis with other common malignant thus prevent its overtreatment.
