• 

  This is a gross photograph of the luminal surface of the esophagus with the area of constriction (1). The area protrudes into the lumen. There is also a central area of ulceration (2).

• 

  This low-power photomicrograph of a cross-section through the esophagus at the area of constriction shows extensive infiltration of the esophageal wall with squamous cell carcinoma (arrows).

• 

  This is a high-power photomicrograph demonstrating the normal epithelium undergoing transition to carcinoma (arrows).

• 

  This is a higher-power photomicrograph showing invasive squamous cell carcinoma. Tongues and islands of tumor cells exhibit areas of central necrosis (arrow).

• 

  This is a photomicrograph of bands of tumor cells invading into the adjacent tissues (arrows).

• 

  This is a higher-power photomicrograph of bands of tumor cells (arrows) extending between the muscle bundles.

• 

  This is a high-power photomicrograph of the tumor cells that have invaded the adjacent muscle tissue.
