title: Warthin's tumor with malignant lymphoma. DNA analysis of paraffin-embedded tissue.
abstract: The authors report a case of malignant lymphoma, small lymphocytic type, involving the lymphoid stroma of a Warthin's tumor of the parotid gland. This was confirmed by the presence of a monoclonal immunoglobulin heavy chain gene rearrangement, demonstrated by Southern blot hybridization of DNA extracted from paraffin-embedded tissue. Similar techniques showed only germline immunoglobulin gene bands in two control cases of Warthin's tumor.
