[A HBV carrier with fulminant hepatitis complicated by ATL, multiple myeloma and thyroid cancer].

A 75-year-old female, born in Tochigi Prefecture, was admitted because of lumbago in August of 1991. The leukocyte count was 11,800/microliters with 22.5% atypical lymphocytes. We demonstrated a lymphocyte surface marker, ATL-associated antigen, and proviral DNA. We also identified 2.60 g/dl of serum monoclonal protein, found to be IgG, lambda type, and punched out lesions in the skull. We made a diagnosis of ATL. She was also a HBV carrier. The patient was treated with a modification of CHOP therapy, because of increasing atypical lymphocytes in the peripheral blood in November of 1992. She died of acute hepatitis, suddenly, in March of 1993. Autopsy revealed multiple myeloma, fulminant hepatitis and occult thyroid cancer in addition to ATL.
