A palpable rectal mass associated with gastrointestinal (GI) symptoms immediately raises concern for colorectal cancer, but rarely can represent distant metastatic disease. The incidence of symptomatic colorectal metastasis from a primary lung cancer without any pulmonary symptom is extremely rare. We report a rare case of constipation as the presenting symptom in a patient ultimately found to have metastatic squamous cell carcinoma of the lung. A rectal mass was readily palpable on examination, illustrating the importance of digital rectal examination. In addition, GI clinicians should maintain a high index of suspicion when evaluating patients at risk of non-GI malignancies.
与胃肠道（GI）症状相关的可触及直肠肿块会立即引发对结直肠癌的担忧，但很少能代表远处转移性疾病。原发性肺癌无任何肺部症状却出现有症状的结直肠转移的发生率极为罕见。我们报告了一例罕见病例，一名患者以便秘为首发症状，最终被发现患有肺转移性鳞状细胞癌。检查时很容易摸到直肠肿块，这说明了直肠指检的重要性。此外，胃肠病临床医生在评估有非胃肠道恶性肿瘤风险的患者时应保持高度警惕。
