Abstract
A case of verrucous squamous carcinoma is reported occurring at the site of obliteration of the esophagus following ingestion of lye 31 years before. The gross, microscopic, and behavioral characteristics are outlined and compared with those of similar tumors developing in the oral cavity, larynx, and genitalia. The morphology and biologic behavior of this rare tumor are distinctive; growth is slow and invasion is a late event. Early diagnosis and surgical therapy may offer a better prognosis than in the more common varieties of esophageal carcinoma.
