**Question:** Intraepidermal blisters are seen in all of the following conditions except –

A. Bullous Pemphigoid
B. Eczema
C. Contact Dermatitis
D. Systemic Lupus Erythematosus

**Core Concept:**
Intraepidermal blisters are a clinical manifestation that can be seen in various dermatological conditions. They occur when the epidermis is breached, allowing fluid to accumulate beneath, leading to blister formation. The blisters can be caused by direct tissue damage or immune-mediated mechanisms.

**Why the Correct Answer is Right:**
The correct answer, Systemic Lupus Erythematosus (SLE), is a condition that primarily affects internal organs and is characterized by autoimmune reactions. Although blisters can occur in SLE, they are not the primary presentation and are usually associated with internal organ involvement or secondary skin manifestations. In this context, intraepidermal blisters are less likely to be seen compared to the other options.

**Why Each Wrong Option is Incorrect:**
A. Bullous Pemphigoid: This is a subepidermal blistering disease caused by autoantibodies against hemidesmosomal proteins. Intraepidermal blisters are seen in this condition.
B. Eczema: Although eczema can cause blistering, it is usually limited to the epidermis and does not typically result in intraepidermal blisters.
C. Contact Dermatitis: This condition is characterized by skin inflammation due to allergic or irritant reactions, which can lead to blistering, but intraepidermal blisters are less common compared to subepidermal blistering diseases like Bullous Pemphigoid.
D. Systemic Lupus Erythematosus (SLE): As mentioned before, intraepidermal blisters are less likely to be seen in SLE compared to the other options.

**Clinical Pearls:**
When examining patients with blistering skin lesions, it is crucial to consider the possibility of Bullous Pemphigoid or other subepidermal blistering diseases, especially when intraepidermal blisters are present. Systemic lupus erythematosus and eczema are often associated with epidermal or subcutaneous blistering, not intraepidermal blisters. Contact dermatitis can cause blistering but usually results in epidermal blisters.
