INTRODUCTION: Bronchiolo-alveolar carcinoma is a primary pulmonary adenocarcinoma developing in the terminal respiratory unit.
CASE REPORT: An 84-year-old non-smoker woman with a history of untreated acute myeloid leukaemia was referred to the intensive care unit for pneumonia and acute respiratory failure. The patient reported dyspnoea and a productive cough for 3 months, treated by antibiotics and steroids without improvement. Thoracic CT-scan showed alveolar condensations and multiple nodular lesions. All microbiological samples were negative and the evolution was fatal within 72 hours despite empirical antibiotic therapy and noninvasive ventilation. Post-mortem lung biopsies gave a diagnosis of mucinous and non-mucinous bronchiolo-alveolar carcinoma with typical lepidic growth pattern of tumor cells and discrete septal thickening but no fibrosis, inflammation or local invasion.
CONCLUSION: Bronchiolo-alveolar carcinoma is an alternative diagnosis in alveolar condensations associated with pulmonary nodules even in a patient with immunosupression. Early diagnosis allows effective treatment in some cases.
