Abstract
A parotid tumor having sebaceous differentiation and a particular histologic picture previously undescribed is reported. The tumor showed features of an adenolymphoma but almost completely lacked a lymphoid component. Sebaceous differentiation was seen in the epithelium of many cysts. Additionally, groups of oxyphilic cells were scattered throughout the tumor. The literature concerning sebaceous differentiation in normal and tumor bearing parotid glands, as well as that concerning tumors with some sebaceous component, is briefly discussed.
