Adenosquamous Carcinoma, Esophagus, Rat
No characteristic macroscopic feature is evident in adenosquamous carcinoma of the esophagus. This neoplasm may have an appearance similar to that of endophytic squamous cell carcinoma, with irregular ulcerations of the surface of the tumor and a conspicuous thickening of the esophageal wall, due to the inward growth of the tumor. In addition, as seen in adenocarcinomas, it may diffusely infiltrate the esophageal wall or project as a mass into the lumen. Adenosquamous carcinomas are predominantly found in the distal esophagus.
