The esophagus is a long hollow tube that starts at the back of your throat and ends at the top of your stomach. Swallowed food travels down the esophagus into the stomach. The inner surface of the esophagus is lined by specialized squamous cells that form a barrier to protect the inside of the esophagus. This thin tissue barrier is called the epithelium.
Squamous papilloma is a common type of non-cancerous growth. It starts from the epithelium lining the inside of the esophagus and is made up of squamous cells that connect together to form long finger-like projections of tissue. Pathologists call these finger-like projections papilla.
The diagnosis is made after the growth is removed and sent to a pathologist for examination under a microscope. Sometimes only a small sample of the papilloma will be removed in a procedure called a biopsy. In these situations, your doctor may suggest a second procedure to remove the remainder of the growth.
