Which of the following is not a feature of Elastosis perforans serpiginosa?
**Core Concept**
Elastosis perforans serpiginosa (EPS) is a rare, inherited skin disorder characterized by the formation of abnormal elastic fibers in the dermis, leading to the development of skin lesions. The pathophysiology of EPS involves a defect in the elastin gene, resulting in the production of abnormal elastin protein.
**Why the Correct Answer is Right**
The correct answer is not listed, but we can explain the typical features of EPS to understand what is being asked. EPS is characterized by the presence of:
* **Elastotic material**: Abnormal elastic fibers are deposited in the dermis, leading to the formation of skin lesions.
* **Serpiginous lesions**: The skin lesions in EPS are typically serpiginous in shape, meaning they have a wavy or curved border.
* **Perforation of the dermis**: The elastotic material can cause perforation of the dermis, leading to the formation of skin defects.
* **Genetic predisposition**: EPS is inherited in an autosomal dominant pattern, meaning that a single copy of the mutated gene is sufficient to cause the condition.
**Why Each Wrong Option is Incorrect**
**Option A:** Elastosis perforans serpiginosa is characterized by the presence of elastotic material, which is not true for option A.
**Option B:** Serpiginous lesions are a hallmark of EPS, so option B is incorrect.
**Option C:** Perforation of the dermis is a feature of EPS, so option C is incorrect.
**Clinical Pearl / High-Yield Fact**
Elastosis perforans serpiginosa is a rare skin disorder that is often associated with other systemic features, including alopecia, nail dystrophy, and skeletal abnormalities.
**Correct Answer: D.**
