A rare case of cervical CD diagnosed at lymph node dissection for esophageal carcinoma is reported. An esophageal tumor was identified in a 67-year-old man during a follow-up examination after surgery for oral carcinoma. Esophagoscopy revealed a type 1 tumor in the cervical esophagus. Histology of esophagoscopic biopsies indicated squamous cell carcinoma. Contrast-enhanced computed tomography revealed swollen lymph nodes of the right cervical region. No distant metastasis was detected. Esophageal carcinoma, T2N2M0, Stage. A was diagnosed. Neoadjuvant chemotherapy was recommended, but the patient rejected the chemotherapy. The patient underwent laparoscopic-assisted transhiatal esophagectomy. The histopathological diagnosis was moderately differentiated squamous cell carcinoma with pT1bN0M0, Stage. A. On histology, the swollen lymph nodes of the right cervical region revealed CD. The patient's postoperative course was relatively good.Baishideng Publishing GroupJournal Articleapplication/pdfhttp://hdl.handle.net/2115/67572https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/67572/1/WJGO9_397.pdf1948-5204World Journal of Gastrointestinal Oncology993974012017-09-15enginfo:doi/10.4251/wjgo.v9.i9.397http://creativecommons.org/licenses/by-nc/4.0/publisher
