**Question:** A 2 years old male is brought to the hospital there is a compressible swelling at the root of nose, likely diagnosis is

A. Angiofibroma
B. Lipoma
C. Angioedema
D. Angioma

**Correct Answer:** C. Angioedema

**Core Concept:** Angioedema is a condition characterized by localized, non-painful, and rapidly resolving swelling due to increased vascular permeability and leakage of plasma proteins into the subcutaneous tissues. It is typically caused by an allergic reaction or medication use, but can also result from genetic disorders like hereditary angioedema (HAE).

**Why the Correct Answer is Right:** Angioedema in children may present with swelling in various body areas, but the root of the nose is a rare location. In this case, the compressible swelling signifies a localized and non-necrotic swelling, which is characteristic of angioedema.

**Why Each Wrong Option is Incorrect:**

A. Angiofibroma: This is a benign tumor consisting of fibroblasts and blood vessels, typically found in the face, particularly in males. It is not compressible and non-allergic in nature, making it less likely.
B. Lipoma: A benign fatty tumor, compressible, and lacks the characteristic edematous swelling seen in angioedema.
D. Angioma: A benign vascular tumor, compressible, and does not cause the rapid edematous swelling found in angioedema.

**Clinical Pearl:** When evaluating a swelling in a pediatric patient, consider the age-appropriate anatomy and pathophysiology. A compressible swelling in a 2-year-old child at the root of the nose should raise suspicion for angioedema, rather than angiofibroma, lipoma, or angioma. Prompt evaluation and treatment are crucial to prevent complications and ensure the child's safety.
