title: Adult T-cell leukemia with a solitary lung mass.
abstract: A 49-year-old woman was admitted to the hospital with supraclavicular lymph node swelling. On a chest x-ray film, a 4 x 4-cm nodular shadow was observed in the right middle lung field. The white blood cell count was 10,100/cu mm, showing 44 percent abnormal lymphocytes with lobulated nuclei. Since HTLV-I antibodies were markedly positive, she was diagnosed as having ATL. Transbronchial tumor biopsy revealed accumulation of ATL cells. Our patient is the first case with only a large nodular accumulation of ATL cells without diffuse infiltration of the cells in the lung.
