Carcinoma pleomórfico do pulmão em doente com síndroma de Mounier-Kuhn

AbstractPleomorphic carcinoma of the lung (PLC) is a rare malignant tumour presenting with a poor clinical outcome. It is included in the group of non-small cell lung carcinomas that contain sarcoma or sarcoma-like components (spindle cells/giant cells).Because of its rarity and diagnostic difficulties, the authors report a case of PLC in a 44 year-old patient, smoker, with the initial clinical presentation of a dorsal tumoural mass. As the time of diagnosis the tumour was in stage IV (TNM), the patient was treated only with supportive therapy and died five months later. During clinical evaluation, a Mounier-Kuhn Syndrome was confirmed.Clinical-imagiological aspects of this situation are reported as well as cytological and immunocytochemical features.Rev Port Pneumol 2006; XII (5): 621-62
