title: [Autopsy case of intravascular lymphomatosis with pancreatic carcinoma].
abstract: We report an autopsy case of intravascular lymphomatosis (IVL) that arose after radiation therapy and chemotherapy for an inoperable pancreatic carcinoma. A 66-year-old man who suffered from diabetes mellitus and pancreatic carcinoma presented with aggressive progression of consciousness disturbance and high fever. The laboratory findings disclosed marked thrombocytopenia, hypercalcemia, and elevated serum PTH-related peptide. The patient soon died of ventricular fibrillation due to uncontrollable hypercalcemia. Postmortem examination with immunohistochemical analysis revealed a well-differentiated tubular adenocarcinoma in the pancreatic body as well as an accumulation of neoplastic B-lymphocytes in small vessels throughout the body without systemic lymphadenopathy. To our knowledge, double neoplasms including IVL are extremely rare.
