Coexistence of sclerosing polycystic adenosis and dysgenetic polycystic disease of parotid, Report of a case

ABSTRACT

Sclerosing polycystic adenosis (SPA) is a rare benign salivary gland lesion. Dysgenetic polycystic disease (DPD), which is a histologically similar lesion, may cause a lattice-like gross appearance with bilateral enlargement of the entire salivary glands. In this report, we present a case of SPA in the right parotid and coexistent DPD involving the both parotid.
