Abstract
|
|
|
|
Sclerosing polycyctic adenosis (SPA) is a rare lesion of unknown etiology morphologically resembling fibrocystic changes of the breast. To our knowledge, 53 cases of SPA have been reported in the literature to date. SPA is well circumscribed, yet not encapsulated. Sclerosing adenosis and cystic ducts with frequent apocrine-like cells were noted. Familiarity with the cytologic and histological features of SPA is very important in making the correct diagnosis. The differential diagnosis of SPA includes polycystic disease, sclerosing sialadenitis and benign/malignant glandular neoplasias. Although atypia ranging from mild dysplasia to carcinoma in situ can occur in some cases, SPA has a favorable outcome. In this article, we describe a 38-year-old male patient diagnosed with SPA in the parotid gland.
