[Autopsy case of pancreatic carcinoma associated with B-cell derived lymphoma].

An autopsy case a 75-year-old man, with papillary adenocarcinoma of the pancreas associated with wide-spread metastasis from a malignant lymphoma is reported. We discuss the markedly lower incidence of pancreatic cancer in syncronal association with lymphoma. We applied an immunoperoxidase method (PAP) in the diffuse large-cell lymphoma to determine the immunological phenotype and found mu heavy chains and lambda light chains in the lymphoma cells. This suggests that the tumor cells were derived from B-lymphocytes.
