N2 - A 63-year-old man was admitted to our hospital with dysphagia. Esophagogastroduodenoscopy revealed a white protruding lesion with keratinization in the lower thoracic esophagus and an esophagobronchial fistula on the left wall of the esophagus, 28 cm from the incisors. Based on the endoscopic findings, esophageal verrucous carcinoma (VC) was suspected. However, the diagnosis could not be confirmed by repeated endoscopic biopsies. Therefore, we performed a boring biopsy along the esophagobronchial fistula, and the immunohistochemistry of the specimens showed an extremely well-differentiated squamous carcinoma with papillary proliferation of the epithelium compressing the surrounding connective tissue while retaining the basement membrane. CT revealed no evidence of distant metastases. Based on these findings, we diagnosed an unresectable esophageal VC with invasion into the left main bronchus. Endoscopic boring biopsy is an effective method for the histological diagnosis of unresectable esophageal VC.
