Oat cell carcinoma of the lung is an aggressive malignancy with a propensity for widespread dissemination. Surprisingly, spread of this tumor to the esophagus from adjacent lung is unusual. Although submucosal involvement has been noted occasionally, overt mucosal ulceration, to our knowledge, has not been demonstrated previously. Two patients with oat cell carcinoma developed painful dysphagia and mucosal ulceration from tumor infiltration into the esophagus.
肺燕麦细胞癌是一种侵袭性恶性肿瘤，易于广泛播散。令人惊讶的是，这种肿瘤从相邻肺组织扩散至食管的情况并不常见。尽管偶尔会发现黏膜下受累，但据我们所知，此前尚未证实有明显的黏膜溃疡。两名燕麦细胞癌患者因肿瘤浸润食管而出现疼痛性吞咽困难和黏膜溃疡。
