Elastosis perforans serpiginosa (EPS) is a rare skin condition that affects the elastic tissue in the skin. It is characterized by the formation of small bumps or papules that develop into raised, snake-like tracks on the skin. In this article, we will discuss the definitions and types of EPS, as well as their details and causes.
Elastosis perforans serpiginosa (EPS) is a rare skin disorder that results from the abnormal accumulation of elastic fibers in the skin. It is characterized by the development of papules or small bumps on the skin, which can eventually form raised, snake-like tracks. EPS is considered a benign condition, as it does not pose any significant health risks. However, it can be a cosmetic concern for some people, particularly if it affects visible areas of the skin.
- Types of Elastosis perforans serpiginosa:
There are two main types of EPS, which are distinguished based on their underlying causes and clinical features.
a. Primary EPS:
Primary EPS is the most common type of EPS, accounting for around 90% of all cases. It typically affects young adults and is more common in men than women. Primary EPS is thought to be caused by a genetic mutation that affects the structure of elastic fibers in the skin. As a result, the elastic fibers become trapped within the skin and form small bumps that eventually form the characteristic snake-like tracks.
b. Secondary EPS:
Secondary EPS is a rare form of the condition that is usually associated with other underlying health conditions. It can occur at any age, and both men and women are equally affected. Secondary EPS can be caused by a variety of factors, including trauma to the skin, inflammatory skin conditions such as acne, or certain medications. In some cases, secondary EPS may be a sign of an underlying autoimmune disorder, such as lupus or rheumatoid arthritis.
Causes
This condition is caused by the accumulation of elastic fibers in the skin, leading to the formation of these bumps and lines. Here are possible causes of EPS:
- Genetic mutations: EPS can be caused by genetic mutations that affect the metabolism of elastic fibers in the skin.
- Inherited conditions: Certain inherited conditions, such as Marfan syndrome or Ehlers-Danlos syndrome, can increase the risk of developing EPS.
- Trauma: Trauma to the skin, such as burns or injuries, can trigger the development of EPS.
- Acne: Acne can cause EPS, particularly in individuals with severe acne.
- Sun exposure: Prolonged exposure to the sun can damage the skin and lead to the development of EPS.
- Inflammatory skin conditions: Inflammatory skin conditions, such as psoriasis or eczema, can increase the risk of developing EPS.
- Autoimmune disorders: Autoimmune disorders, such as lupus or rheumatoid arthritis, can increase the risk of developing EPS.
- Medications: Certain medications, such as isotretinoin or penicillamine, can increase the risk of developing EPS.
- Chronic kidney disease: Chronic kidney disease can increase the risk of developing EPS.
- Liver disease: Liver disease can increase the risk of developing EPS.
- Diabetes: Diabetes can increase the risk of developing EPS.
- HIV/AIDS: HIV/AIDS can increase the risk of developing EPS.

Symptoms
Symptoms of EPS in detail.
- Bumps on the skin: The primary symptom of EPS is the development of small, raised bumps on the skin. These bumps can be flesh-colored, pink, or red.
- Snake-like pattern: The bumps of EPS can form a snake-like pattern on the skin. This pattern is characterized by a series of bumps that are connected in a wavy or serpentine shape.
- Itchy skin: Many people with EPS experience itchiness in the affected areas. This can be mild to severe and can interfere with daily activities.
- Burning or stinging sensation: In addition to itchiness, some people with EPS may experience a burning or stinging sensation in the affected areas.
- Scaly skin: The bumps of EPS can cause the skin to become scaly or rough to the touch.
- Skin discoloration: Over time, the skin affected by EPS may become discolored. This can range from lightening of the skin to darkening.
- Skin thickening: In some cases, the skin affected by EPS may become thicker than normal.
- Lesions: EPS can lead to the formation of lesions on the skin. These can be small or large and can be painful or tender to the touch.
- Crusting: Some people with EPS may experience crusting on the skin in the affected areas.
- Pus-filled bumps: In rare cases, the bumps of EPS can become infected and fill with pus.
- Skin erosion: Over time, the bumps of EPS can cause the skin to erode. This can lead to the formation of open sores.
- Skin ulceration: In severe cases, EPS can lead to skin ulceration. This occurs when the skin breaks down and exposes the underlying tissue.
- Nail abnormalities: In some cases, EPS can lead to nail abnormalities. This can include thickening or discoloration of the nails.
- Eye problems: In rare cases, EPS can affect the eyes. This can lead to problems with vision or inflammation of the eye.
- Joint pain: Some people with EPS may experience joint pain. This can be mild to severe and can affect any joint in the body.
- Fatigue: In addition to joint pain, some people with EPS may experience fatigue or a general feeling of malaise.
- Headaches: Headaches are a common symptom of EPS. These can be mild to severe and can be accompanied by other symptoms such as dizziness or nausea.
- Fever: In rare cases, EPS can cause a fever. This is usually a sign of infection and requires prompt medical attention.
- Swollen lymph nodes: In some cases, EPS can cause swelling of the lymph nodes. This is a sign that the body is fighting an infection.
- Difficulty breathing: In rare cases, EPS can affect the lungs and cause difficulty breathing. This requires prompt medical attention.
Diagnosis
If you suspect that you or a loved one may have EPS, it’s important to seek medical attention from a dermatologist who can help diagnose and treat the condition. Here are common diagnosis and tests for EPS:
- Skin biopsy: A skin biopsy involves taking a small sample of skin tissue and examining it under a microscope to look for changes in the elastic fibers.
- Dermoscopy: A dermoscope is a handheld device that allows the dermatologist to examine the skin closely and look for characteristic patterns of EPS.
- Blood tests: Blood tests may be ordered to check for underlying medical conditions that may be associated with EPS.
- X-rays: X-rays can be used to check for bone abnormalities in cases where EPS is associated with connective tissue disorders.
