Nonsebaceous lymphadenoma (NSL) is an unusual benign salivary gland tumor characterized by a predominant lymphoid background, dense lymphoid infiltrate, and absence of sebaceous differentiation. To our knowledge, only 10 previous cases have been reported in the literature. We report an additional case of NSL arising in the parotid gland in 58-year-old female patient. The extensive immunohistochemical investigation of the tumor revealed the presence of both luminal and myoepithelial cells. DNA analysis for flow cytometry was performed. The histogram presented a single peak in the G0-G1 area. The tumor was considered as being DNA diploid.
