Dyspnea and cyanosis are common presenting manifestations of cardiopulmonary disease. When these findings occur in a cigarette smoker with an apparent pulmonary mass on chest radiograph, the differential diagnosis rapidly narrows to a short list of possibilities that include pulmonary neoplasm, pulmonary infection and pulmonary infarction. Pulmonary hypertension with pulmonary arterial enlargement and hypoxia secondary to alveolar hypoventilation should also, however, be included as a diagnostic possibility in the appropriate setting because the evaluation and treatment of this entity may differ markedly.
呼吸困难和发绀是心肺疾病常见的临床表现。当这些表现出现在一名吸烟者身上，且胸部X线片显示有明显肺部肿块时，鉴别诊断很快就会缩小到一小串可能性，包括肺部肿瘤、肺部感染和肺梗死。然而，在适当的情况下，继发于肺泡通气不足的肺动脉高压伴肺动脉扩大和低氧血症也应作为一种诊断可能性纳入，因为对该疾病的评估和治疗可能会有显著差异。
