## **Core Concept**
Coeliac disease is a chronic autoimmune disorder primarily affecting the small intestine, triggered by the ingestion of gluten in genetically predisposed individuals. The condition leads to mucosal inflammation, atrophy of the villi, and crypt hyperplasia. Histological examination of intestinal biopsies is crucial for diagnosing coeliac disease.

## **Why the Correct Answer is Right**
The correct answer, , is associated with a feature not typically seen in coeliac disease. In coeliac disease, characteristic histological features include:
- **Villar atrophy**: Reduction in the height of the villi, which can range from partial to total atrophy.
- **Crypt hyperplasia**: Increase in the depth of the intestinal crypts.
- **Increased intraepithelial lymphocytes (IELs)**: A hallmark of the condition, where there is an increase in the number of lymphocytes within the epithelial layer.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Increased intraepithelial lymphocytes are a hallmark of coeliac disease, making this option a feature of the condition.
- **Option B:** Crypt hyperplasia is another characteristic feature, indicating the body's attempt to compensate for the loss of absorptive surface area.
- **Option C:** Villar atrophy is a key diagnostic criterion, reflecting the damage caused by the immune response to gluten.

## **Clinical Pearl / High-Yield Fact**
A crucial point to remember is that while histological features are essential for diagnosis, clinical correlation and serological tests (like tissue transglutaminase antibody and endomysial antibody tests) are also critical. Moreover, a strict gluten-free diet is the only treatment for coeliac disease.

## **Correct Answer:** . Increased goblet cells.
