ulceration
Meaning of ulceration: A description rather than a diagnosis, telling a reader that a surface has been lost and something is stopping it from closing.
Definition of ulceration
Ulceration is the breakdown of a surface layer of tissue to leave an open sore that extends into the layer beneath. It occurs on skin, on the lining of the mouth, stomach and bowel, and on the surface of the eye. Because the loss reaches below the surface, healing is slow and usually leaves a scar rather than restoring the original layer.
How deep does it go?
| Term | Depth | How it heals |
|---|---|---|
| Abrasion | Scraped surface only | Quickly, without a scar |
| Erosion | Surface layer lost, base intact | Fully, without a scar |
| Ulcer | Through the surface into the layer below | Slowly, usually with scarring |
| Fissure | A narrow split rather than a crater | Depends on depth and tension |
That distinction does real work in a report. An erosion of the stomach lining and an ulcer of the same lining carry different consequences, because only the deeper defect reaches the blood vessels and the muscle coat, and only the deeper one can bleed heavily or perforate.
What makes tissue break down?
Anything that starves a surface of blood or attacks it faster than it can rebuild. Pressure over a bony point flattens the vessels underneath and the skin above dies for want of supply. Narrowed arteries do the same on the foot and lower leg. Sluggish veins raise the pressure inside the skin of the ankle and produce a different sore with a different look. Stomach acid and digestive enzymes eat into a lining whose protective coating has been weakened. Long-standing infection, immune attack in inflammatory bowel disease, radiation, and a tumor that outgrows its own blood supply all end in the same appearance. This is why the word describes a wound without saying anything about what produced it.
Why does it get recorded so carefully?
Because the finding changes what follows. A skin ulcer deep enough to touch bone raises the question of osteomyelitis, infection settled in the bone itself, which is managed over far longer than a soft tissue infection. A sore that refuses to heal despite an adequate blood supply is sampled, since a skin cancer can arise in one of long standing. In melanoma, ulceration seen under the microscope carries weight of its own, moving a tumor into a higher stage than its thickness alone would give, which is why a report on a thin lesion such as stage I melanoma states whether it is present.

The endoscopy report noted ulceration of the gastric antrum with no active bleeding.
Good to know
Ulceration names an appearance rather than a cause, and sores that look alike arise from pressure, arterial disease, venous congestion, infection or tumor, each of which behaves differently.
Word origin
Where “ulceration” comes from
From the Latin ulcus, ulceris, meaning a sore.
