**Question:** Peau de orange appearance is due to

A. Alcohol consumption
B. Vitamin A deficiency
C. Liver disease
D. Pregnancy

**Core Concept:** Peau de orange, also known as "orange peel skin," is a clinical sign characterized by a rough, orange, and papular skin rash. It is often associated with underlying pathologies affecting the liver, kidneys, or thyroid gland.

**Why the Correct Answer is Right:** Peau de orange (B) is correct because it is a manifestation of vitamin A deficiency. Vitamin A plays a crucial role in maintaining skin integrity, including barrier function and collagen synthesis. Its deficiency leads to impaired skin repair, resulting in the characteristic orange peel appearance.

**Why Each Wrong Option is Incorrect:**

A. Alcohol consumption (A) may cause skin changes, but peau de orange is not a common feature. Alcohol's effects on the liver and other organs, rather than the skin, are more likely to cause clinical manifestations.

C. Liver disease (C) may present with various skin findings, but peau de orange is not a typical finding unless the deficiency is severe or combined with vitamin A deficiency. Liver disease-related skin manifestations often involve itching, jaundice, or scleral icterus.

D. Pregnancy (D) can cause changes in skin pigmentation, but peau de orange is not a common feature. Instead, pregnancy-related skin changes like acanthosis nigricans or melisma are more likely.

**Clinical Pearl:** Peau de orange is an important clinical sign to recognize, as it can indicate a more serious underlying condition, such as vitamin A deficiency or advanced liver disease. A thorough history and examination, including dermatological examination, are essential for accurate diagnosis and appropriate management.
