近5年我科共收治皮肌炎患者13例,经住院观察发现4例伴有恶性肿瘤,其中2例伴食管癌,1例为鼻咽癌,另1例为转移癌但原发部位不清楚。由于皮肌炎患者舌部、咽部及食道上1/3肌肉受侵,患者常出现吞咽困难,这时容易与食管癌吞咽困难相混淆,特别是40岁以上的患者。因此,仔细地作食道检查甚为必要。 In the past 5 years, 13 cases of dermatomyositis were treated in our department. Four patients with malignant tumors were found in the hospital, including 2 with esophageal cancer, 1 with nasopharyngeal carcinoma and 1 with metastatic carcinoma but with no primary site clear. Due to dermatomyositis in the tongue, pharynx and esophagus on the 1/3 of muscle invasion, patients often have difficulty swallowing, when easy to swallow esophageal cancer and confusion, especially in patients over the age of 40. Therefore, careful examination of the esophagus is necessary.
