Sclerosing Polycystic Adenosis of the minor salivary gland: case report.

Sclerosing Polycystic Adenosis (SPA) is a rare disease of the salivary glands, first described by Smith et al. in 1996, with histomorphological aspects similar to those from breast fibrocystic disorders1. Its pathogenesis is still unclear; however, it is considered a pseudo-neoplastic or reactive process. Recently, Skálová et al. showed clonality in six SPA cases. SPA affects mainly the parotid and submandibular glands, being much less frequent on the minor salivary glands. Here, we report a case of SPA in a minor salivary gland and we discuss its histomorphological aspects.
