RESUMEN
INTRODUCTION: Bronchiolo-alveolar carcinoma is a controversial indication for lung transplantation because of the risk of recurrence. We report three cases and propose some risk factors for recurrence. CASE REPORTS: Our study concerns three patients transplanted at the Louis-Pradel Hospital between 1991 and 2010. The first patient relapsed 86 months after transplantation, benefited from surgical treatment, then died of renal failure. A second patient died of infection, without recurrence, 72 months after transplantation. The third had an early recurrence at 7 months and died 27 months after transplantation. The risk factors for recurrence appear to be: clinically "aggressive" presentation and histological stromal pulmonary invasion by the carcinoma. CONCLUSION: Diffuse bronchiolo-alveolar carcinoma is a possible indication of lung transplantation. The risk of recurrence imposes some requirements: a precise histological diagnosis and a slow clinical course.
