Secondary esophageal carcinoma: report of two cases showing intraluminal tumor

Two cases of secondary esophageal carcinoma showing intraluminal tumor are reported here. The one from pancreatic carcinoma showed a solitary sessile tumor which was misdiagnosed as primary adenocarcinoma of the esophagus. The other from epipharyngeal cancer revealed small multiple nodules of the mid-esophagus. When an esophageal tumor is noted, the possibility of esophageal metastasis should be included in the differential diagnosis especially when tumors are multiple and are accompanied with central depression or have a tendency of intramural filling defect.
