Linitis plastica is a feature of –
**Core Concept**
Linitis plastica, also known as Brinton's disease, is a diffuse gastric cancer characterized by a hardened, leather-like stomach wall. This condition results from the infiltration of gastric mucosa by adenocarcinoma cells, leading to fibrosis and thickening of the gastric wall.
**Why the Correct Answer is Right**
The correct answer is associated with a specific type of gastric cancer. Linitis plastica is typically caused by signet ring cell carcinoma, a subtype of adenocarcinoma that originates from the gastric mucosa. The signet ring cells secrete mucin, leading to the infiltration and fibrosis of the gastric wall. The resulting thickening of the stomach wall causes it to resemble a leather-like texture.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as linitis plastica is not typically associated with intestinal-type adenocarcinoma, which is a different subtype of gastric cancer.
**Option B:** This option is incorrect as chronic gastritis, while it can cause scarring and thickening of the gastric wall, does not result in the characteristic leather-like appearance of linitis plastica.
**Option C:** This option is incorrect as gastric lymphoma can cause thickening of the gastric wall, but it does not typically result in the diffuse infiltration and fibrosis characteristic of linitis plastica.
**Clinical Pearl / High-Yield Fact**
Linitis plastica is often referred to as "leather-bottle stomach" due to its characteristic appearance on imaging studies. This term is a useful mnemonic for remembering the association between linitis plastica and signet ring cell carcinoma.
**Correct Answer:** D.
