Polymorphous light eruption (PMLE)

Overview

Polymorphous light eruption (PMLE) is a common skin condition that occurs when the skin reacts to sunlight, particularly in the spring and early summer when the sun's rays are strongest. PMLE is characterized by a rash that can appear on various parts of the body, such as the front of the neck and chest. The rash can take many forms, including tiny bumps, raised areas, or blisters.

Types of Polymorphous light eruption (PMLE)

PMLE is a type of photodermatitis, which is a skin reaction caused by exposure to sunlight. There are two main types of PMLE:

1. Acute PMLE: This type of PMLE is characterized by a sudden onset of symptoms, typically within minutes or hours of exposure to sunlight. The rash usually lasts for several days and then resolves on its own.
2. Chronic PMLE: This type of PMLE is characterized by recurring symptoms that can last for several weeks or months.

Causes of Polymorphous light eruption (PMLE)

The exact cause of PMLE is unknown, but it is believed to be triggered by an abnormal reaction to ultraviolet (UV) light in the sun's rays. UV light can cause damage to the skin's DNA, leading to inflammation and the development of symptoms.

Risk Factors of Polymorphous light eruption (PMLE)

Individuals who are more likely to develop PMLE include:

1. Fair skin: People with fair skin are more susceptible to PMLE because they have less melanin, which is the skin's natural pigment that helps protect against UV light.
2. Family history: If you have a family history of PMLE, you may be more likely to develop the condition.
3. Previous episodes: If you have had previous episodes of PMLE, you may be more likely to experience it again in the future.

2. Use sunscreen: Use a broad-spectrum sunscreen with an SPF of 30 or higher and apply it regularly throughout the day.
3. Seek shade: Whenever possible, seek shade or stay indoors during peak sun hours (usually between 10am and 4pm).

Diagnosis of Polymorphous light eruption (PMLE)

PMLE is typically diagnosed based on a physical examination and medical history. Your doctor may also perform a patch test to confirm the diagnosis.

Treatment for Polymorphous light eruption (PMLE)

There is no cure for PMLE, but there are several treatments that can help manage symptoms:

1. Topical corticosteroids: Topical corticosteroids can help reduce inflammation and itching.
2. Topical antihistamines: Topical antihistamines can help reduce itching and relieve discomfort.
