The esophagus is present in the chest. It’s about 10 inches wide. This organ is part of the intestinal system. Food moves from the oral cavity through the esophagus to the abdomen.
The esophagus is a muscular tube. The wall of the esophagus has several layers:
- Inner layer: The coating of the esophagus is moist so that food can pass to the stomach.
- Sub mucosa: The glands in this layer make mucus. Mucus keeps the esophagus moist.
- Muscle layer: The muscles force the food down to the stomach.
- Outer layer: The outer layer protects the esophagus.
Some facts about esophagus melanoma are:
- While the actual cause(s) of melanoma of the wind pipe is not known, risks have been determined.
- The chance of melanoma of the wind pipe is improved by long-term irritation of the wind pipe, such as with cigarette smoking, high liquor consumption, and Barrett’s esophagitis.
- Diagnosis of this cancer can be made by barium X-ray of the wind pipe and verified by endoscopy with biopsy of the cancer cells.

There are mainly two types of esophageal cancer. Both types are clinically diagnosed, handled, and managed in similar ways. The two most common types are known for how the cancer cells look under a microscopic lense. Both types begin in cells in the inner coating of the esophagus:
- Adenocarcinoma of the esophagus: This type is usually found in the lower part of the esophagus, near the abdomen. In the U.S. adenocarcinoma is the most common type of esophageal cancer. It’s been increasing since 1970s.
- Squamous cell carcinoma of the esophagus: This type is usually found in the upper part of the esophagus. This type is becoming less common among Americans. Around the world, squamous cell carcinoma is the most common type.
Early esophageal cancer may not cause signs. As the cancer grows, the most common symptoms are:
- Chest pain
- Pain when swallowing
- Heart pain
- Weight loss
- Cough that doesn’t go away within 2 weeks
These signs may be due to esophageal melanoma or other illnesses. If you have any of these signs, you should concern your physician so that issues can be clinically diagnosed and handled as early as possible.
