title: Sclerosing polycystic sialadenopathy: a rare cause of recurrent tumor of the parotid gland.
abstract: We present a case report of a woman with a recurrent parotid mass that was histologically confirmed to be sclerosing polycystic sialadenopathy, a rarely reported cause of salivary gland tumor. This tumor measured 11.8 x 6 cm, the largest such lesion yet reported. Histologic analysis revealed foci of atypical intraductal acinic cell proliferation and necrosis severe enough to amount to intraductal carcinoma in situ. Despite its large size, it was successfully excised, leaving the patient with only moderate facial nerve dysfunction postoperatively.
