Warthin tumor exhibiting sebaceous differentiation and necrotizing sialometaplasia.
A case of Warthin tumor exhibiting sebaceous differentiation and necrotizing sialometaplasia is presented. This case suggests a common histogenesis for the Warthin tumor and sebaceous lymphadenoma. It supports the theory that necrotizing sialometaplasia is caused by factors which compromise or obstruct the blood supply to salivary gland tissues. The literature on sebaceous differentiation in Warthin tumor and on necrotizing sialometaplasia is reviewed.
