title: Warthin tumor. B-lymphocytes within the lymphoid infiltrate.
abstract: The lymphoid stroma in Warthin tumor is predominantly composed of complement receptor B-lymphocytes. These lymphocytes are present in a pattern similar to that observed in reactive lymph nodes. The B-lymphocytes may be residual lymph node elements exhibiting reactivity directed toward the epithelial component of the tumor.
