Esophageal superficial adenosquamous carcinoma resected by endoscopic submucosal dissection: A rare case report

Figure 3 Dilated and tortuous vessels were observed around and within the ductal-structure-forming cancer cell nests. A: Specimen resected by endoscopic submucosal dissection; B: Histological view of the resected lesion revealed that the squamous cell carcinoma element was the predominant element, and the adenocarcinoma element was distributed in a focal pattern among the squamous cell carcinoma element; C-E: High-power view revealed invasive carcinoma forming ductal structures distributed among squamous cell carcinoma. Part of the lesion was covered by dyskeratotic squamous cells.
