Esophageal squamous cell carcinoma in situ overlying leiomyoma mimicking invasive cancer: a brief case report.

Abstract

Leiomyoma is the most common benign submucosal mesenchymal tumor of the esophagus, and squamous cell carcinoma is most common epithelial tumor of the esophagus. However, esophageal squamous cell carcinoma overlying leiomyoma has rarely been reported. Herein, we report a case of esophageal squamous cell carcinoma in situ overlying leiomyoma. In addition, we reviewed other reported cases of esophageal squamous cell carcinoma overlying leiomyoma.
