A 43-year-old male was admitted to the hospital with a complaint of mild dysphagia. A barium esophagogram showed an annular narrowing in the lower esophagus. Further, an endoscopic examination revealed erosive mucosa of the esophagus about 35 cm anal to the incisor. Lugol staining also revealed a geographical unstained lesion. The histologic diagnosis of a biopsy specimen indicated a squamous cell carcinoma and a total resection of the esophagus was performed. The operated material macroscopically showed a tumor of a superficially mixed type (IIa + IIc + IIb). The resected specimen histologically consisted of 18 squamous carcinomas that were separated with the normal squamous epithelium from each other. The major part of these lesions were limited to the epithelium, and only a few specimens microscopically showed an invasion of cancer nests in the propria mucosae. Great permeation of cancer cells into lymph vessels and the metastasis of one regional lymph node also were noted. Taken together, these findings indicated that the squamous cell carcinomas of this case seemed to have multicentrically developed from the normal esophageal mucosa.
