This lesion can be confused with lymphoepithelial sialadenitis. Kuttner tumors can be distinguished from lymphoepithelial sialadenitis by the lack of lymphoepithelial lesions and more prominent sclerosis.
Lymphoepithelial Sialadenitis (Benign Lymphoepithelial Lesion)
Lymphoepithelial sialadenitis is previously known as myoepithelial sialadenitis or benign lymphoepithelial lesion.
However, Warthin tumors are characterized by aggregates of oncocytes and usually are associated with a more monomorphic population of lymphocytes as compared with the lymphoid population in lymphoepithelial sialadenitis. The oncocytic clusters of Warthin tumors are usually not associated with lymphocyte infiltration either.
