Here is a comprehensive answer based on authoritative pathology and gastroenterology textbooks.
Stomach Carcinoma: Ulcers vs. Linitis Plastica
The short answer is: ulcers and linitis plastica are distinct morphological presentations of gastric carcinoma, not the same thing. However, they can co-exist in some forms. Here is the full picture:
Macroscopic (Gross) Presentations — Borrmann Classification
Advanced gastric cancers are classified by the Borrmann system into four types:
| Type | Description |
|---|---|
| I | Polypoid / fungating mass |
| II | Ulcerative with elevated, distinct borders |
| III | Ulcerative with indistinct borders (infiltrative) |
| IV | Diffuse infiltrative — also called linitis plastica |
Types I & II are localized; Types III & IV are infiltrative. — Yamada's Textbook of Gastroenterology, 7th ed.
Linitis Plastica (Borrmann Type IV)
- Linitis plastica is the diffuse infiltrative form of gastric cancer, predominantly caused by signet ring cell (poorly cohesive) adenocarcinoma.
- Tumor cells permeate the entire gastric wall as small clusters and individual discohesive cells, driven by loss of E-cadherin (CDH1 mutations).
- The infiltrating cells evoke a desmoplastic (fibrotic) reaction, stiffening the gastric wall.
- When large areas are involved, this produces diffuse rugal flattening and a rigid, thickened wall — the classic "leather bottle" (linitis plastica) appearance.
- There is no discrete ulcer or mass in pure linitis plastica — the stomach is diffusely contracted and non-distensible.
"A mass may be difficult to appreciate in diffuse gastric cancer, but the infiltrative tumors often evoke a desmoplastic reaction that stiffens the gastric wall. When there are large areas of infiltration, diffuse rugal flattening and a rigid, thickened wall may impart a leather bottle appearance termed linitis plastica." — Robbins & Cotran Pathologic Basis of Disease

Ulcerative Presentations (Borrmann Types II & III)
- Ulcers occur mainly in intestinal-type adenocarcinoma (Laurén classification), which grows along broad cohesive fronts to form exophytic masses or ulcerated infiltrative tumors.
- The ulcers have heaped-up, irregular borders (unlike benign peptic ulcers with smooth, punched-out edges).
- Borrmann Type II = ulcerated with clear, elevated margins.
- Borrmann Type III = ulcerated with indistinct, infiltrating margins — this is the overlap zone where ulceration and infiltration co-exist.
Key Distinction
| Feature | Ulcerative (Type II/III) | Linitis Plastica (Type IV) |
|---|---|---|
| Histology | Intestinal-type adenocarcinoma | Diffuse (signet ring) type |
| Gross appearance | Ulcer with raised borders | Rigid, thickened wall, no distinct ulcer |
| Wall behavior | Focal infiltration | Diffuse wall involvement |
| E-cadherin | Usually intact | Lost (CDH1 mutation) |
| Distensibility | Preserved regionally | Severely impaired globally |
| Prognosis | Slightly better | Very poor |
Can They Co-exist?
Borrmann Type III represents a partial overlap — it has both ulceration and indistinct infiltrating borders. However, true linitis plastica (Type IV) does not primarily present as an ulcer — it presents as a diffusely contracted, non-distensible stomach. The primary presentation of linitis plastica is early satiety, weight loss, and a non-distensible stomach on endoscopy or imaging, not ulcer-type pain.
Summary: Ulcerative and linitis plastica forms are distinct morphological subtypes of gastric carcinoma. Ulcers are the hallmark of intestinal-type (Borrmann II/III), whereas linitis plastica is the hallmark of diffuse-type signet ring cell carcinoma (Borrmann IV). The main presentations of stomach carcinoma are polypoid/fungating, ulcerative, and diffusely infiltrative (linitis plastica) — not "ulcers mainly" with linitis plastica being secondary.
