Understanding Subacute (Active) Lichen Planus: Symptoms and Causes

Subacute lichen planus, also known as active lichen planus, is a relatively common skin condition that affects many individuals worldwide. It falls under the broader category of lichen planus, which is characterized by the development of itchy, flat-topped, purple-colored bumps on the skin. In this article, we will delve into the symptoms and causes of subacute lichen planus.

Symptoms of Subacute Lichen Planus:

1. Skin rash: The primary symptom of subacute lichen planus is the presence of a red or purple rash on the skin. These rashes often appear as small, raised bumps that may be itchy or painful.
2. Oral lesions: In some cases, subacute lichen planus can also affect the mucous membranes inside the mouth. This can lead to the development of painful, white, lacy patches or sores.
3. Nail abnormalities: Subacute lichen planus may cause changes in the appearance of the nails, such as ridges, grooves, or thinning.
4. Itching: Many individuals with subacute lichen planus experience intense itching, especially at night or after exposure to heat.

Causes of Subacute Lichen Planus:

The exact cause of subacute lichen planus remains unknown, but several factors are believed to contribute to its development:

1. Autoimmune response: Lichen planus is thought to be an autoimmune disorder, where the immune system mistakenly attacks healthy cells in the skin or mucous membranes.
2. Genetic predisposition: Certain genetic factors may increase an individual's susceptibility to developing subacute lichen planus.
3. Triggering factors: Various triggering factors, such as certain medications, viral infections, stress, or exposure to certain chemicals, may initiate or worsen the symptoms of subacute lichen planus.

It is worth noting that subacute lichen planus is not contagious, meaning it cannot be transmitted from person to person. If you suspect you have subacute lichen planus or experience any concerning symptoms, it is always advisable to consult a qualified dermatologist for an accurate diagnosis and appropriate treatment.

In conclusion, subacute lichen planus is a skin condition characterized by a rash, oral lesions, nail abnormalities, and intense itching. While the exact cause of this condition is unknown, it is believed to involve an autoimmune response,
