Abstract
For classification purposes, proper identification of infrequent and unique salivary gland tumors requires the gradual accumulation of a sufficient number of cases. Lymphadenoma (i.e., an adenomatous, generally parotid-based lesion with an exaggerated lymphocytic infiltrate, but a lack of sebaceous differentiation) has approximately 9 reported cases. This report adds 2 additional cases occurring as a discrete, at least partially encapsulated nodule in the parotid gland. Embedded within the extensive lymphocytic component were isolated nests of solid or glandular epithelium, with 1 case displaying a few foci of chondrocytic differentiation. Immunohistochemical investigation of the latter case revealed the presence of both luminal and myoepithelial cells.
