[A human T-cell lymphotropic virus type 1 carrier presenting with Sjögren's syndrome and bronchopneumopathy].

A 77-year-old asymptomatic woman was found to have a coin lesion on a chest radiograph. Chest computed tomography scans showed the coin lesion, bronchiectasis, tree-in-bud appearance, and ground glass opacity. The histopathology of the lung by video-assisted thoracic surgery showed organizing pneumonia, follicular bronchiolitis, and non-specific interstitial pneumonitis patterns, all of which consisted of mainly mature lymphocytes and plasma cells. She suffered from dry eyes and had a high level of serum anti-SS-A antibody. Examination of her eyes and mouth revealed Sjögren's syndrome. The patient herself and her parents were born in Nagasaki prefecture, an area where human T-cell lymphotropic virus type 1 (HTLV-1) is endemic, and her sister suffered from a hematological malignancy. She was found to be an HTLV-1 carrier. We finally made a diagnosis of an HTLV-1 carrier presenting with Sjögren's syndrome and bronchopneumopathy. This combination (HTLV-1, Sjögren's syndrome, and bronchopneumopathy) is rarely reported.
