[Esophageal implantation metastasis from adenocarcinoma of the cardia].

A 74 years old male patient was admitted to our department suffering from dysphagia for five months. Gastric Barium studies showed a cardia tumour with polypoid lesions in the wall of the esophagus, and gastro-esophageal reflux disease was also diagnosed. Endoscopy verified a cardia tumour with esophageal metastasis, and biopsy was obtained from the two lesions. Histology showed that both tumours were adenocarcinomas. Endoscopic ultrasonography classified the cardia tumour as grade T2. As observed during endoscopy, the wall of the esophagus at the level of the polypoid lesion was hypo-echogenic and thick which was result of thickened mucosa. Total gastrectomy and oesophagectomy was performed. Pathology showed that the cardia tumour was pT2N2 and type Siewert-Stein II. The esophageal polypoid lesion was also proved an adenocarcinoma, which was localized only to the mucosa. No tumour cells were found in the blood- or in lymph vessels between the tumour and the esophageal adenocarcinoma. We think that the polypoid adenocarcinoma in the esophagus is an esophageal metastasis implantation from the cardia adenocarcinoma. It is based on the exclusion of other possible tumour dissemination routes. Probably the gastro-esophageal reflux is responsible for the implantation of tumour cells.
