Abstract
A very rare case of esophageal leiomyoma associated with esophageal cancer in a 57-year-old woman was reported. The patient was found to have a small intramural tumor in the middle intrathoracic esophagus by upper gastrointestinal series. Endoscopic biopsies, revealed a moderate dysplasia of esophageal epithelium on the top of the same elevated region. The patient underwent partial resection of the esophagus by right lateral thoracotomy. Microscopically, the resected tumor measuring 0.7×1.2cm was composed of interlacing bundes of smooth muscle Microscopically, the resected tumor measuring 0.7×1.2cm was composed of interlacing bundes of smooth muscle Microscopically, the resected tumor measuring 0.7×1.2cm was composed of interlacing bundes of smooth muscle correlation between the esophageal leiomyoma and cancer. We speculate that not only chronic mechanical stimulation to the epithelium covering the leiomyoma by usual swallowing but also some other common factors might cause the esophageal cancer.
