[A case of spontaneous regression of malignant lymphoma, complicated with miliary tuberculosis, liver dysfunction and pancytopenia].

An 82-year-old woman was admitted to Iwamizawa Rosai Hospital, Cardiovascular Medicine, for detailed examination of an aneurysm of abdominal aorta. CT scan revealed marked swelling of para-aortic lymph nodes which regressed spontaneously in three months. She was re-admitted to our hospital because of general malaise and gait disturbance. Her chest X-ray on the second admission revealed miliary disseminated shadows, which were confirmed to be tuberculous granuloma by lung biopsy. She was initially well controlled with anti-tuberculosis drugs, followed by severe liver dysfunction and pancytopenia, and died of respiratory and cardiac failure. At autopsy, wide-spread malignant lymphoma and miliary tuberculosis of the lung were found. The cause of liver dysfunction was strongly suspected to be due to infiltration of the lymphoma cells to portal triads of the liver. Hemophagocytosis found in the bone marrow, spleen and liver might be consistent with clinically so-called "hemophagocytic syndrome", causing pancytopenia, associated with infection.
