Immunohistochemical Study of Esophageal Carcinomas Other Than Squamous Cell Carcinoma
It was previously thought that esophageal carcinomas other than squamous cell carcinoma were very rare; for example, Suzuki and Nagayo found 256 (2.1%) of 11,932 resected cases and 360 (7.2%) of 4995 autopsied cases of the esophagus . However, recently some authors have indicated that these tumors were not so rare [2, 3]. We found 29 cases (12.7%) of these carcinomas among 229 resected cases of esophageal carcinoma from 1978 to 1991, we interested the histological origins of the 29 cases (12.7%) of non-squamous cell carcinoma. These tumors were immunohistochemically stained for the purpose of determination of their histological origin and/or differentiation.
