Signet-ring cell carcinoma of the esophagus associated with Barrett's epithelium: report of a case.

We herein report a case of infiltrative esophageal signet-ring cell carcinoma resembling gastric signet-ring cell carcinoma. Grossly, the tumor was a diffusely infiltrative carcinoma involving the lower esophagus measuring 11 cm in diameter. The tumor extensively metastasized to the cervical, mediastinal, and abdominal lymph nodes, and the patient died of peritonitis and pleuritis carcinomatosa soon after undergoing a radical esophagectomy.
