Abstract
Patient was a 70-year-old male, who came to the hospital with the chief complaint of dysphagia. Upper gastrointestinal series showed a protruded lesion with an irregular surface at the upper esophagus. On endoscopy, a reddish brown, semipedunculated mass with a cauliflower-like appearance was detected on the posterior wall of the esophagus at 20 cm from incisors. An esophageal cancer was suspected, sub-total esophagectomy was performed. The size of the tumor resected was 6.0 x 5.5 x 2.0 cm. Histologically, it was a well-differentiated squamous cell carcinoma with papillary proliferation of epithelium, which compressed the surrounding connective tissue. However, basement membrane was retained. From these findings, the lesion was diagnosed as verrucous squamous cell carcinoma.Esophageal verrucous squamous cell carcinoma is extremely rare, and only 10 cases have been reported by the end of 1986. The author discussed the clinical and histopathological characteristics of esophageal verrucous squamous cell carcinoma on the basis of findings of 11 cases comprising our case and 10 documented cases.
