Abstract:
A 57-year-old woman was referred to our hospital for further examination of a tracheal stenosis shown on computed tomography findings. Bronchoscopy revealed multiple protruding tumors in the lumen of the trachea. Cytological findings of the cell block material from pleural effusion indicated that the T-cell lymphoma was composed of pleomorphic lymphoid cells. Serum human T-cell leukemia virus type 1 antibody was positive and supported the clinical diagnosis of ATLL. Systemic chemotherapy induced the remarkable improvement of the lesions, the infiltrative lung shadow and the soft tissue neoplasm. We report a rare case of adult T cell leukemia/lymphoma (ATLL) with endobronchial involvement.
