Lichen Planus-Like Keratosis (LPLK) is a skin condition that can cause discomfort and concern. In this article, we will provide you with simple explanations of what LPLK is, its types, common causes, symptoms, diagnostic tests, treatment options, and drugs used to manage it.
Lichen Planus-Like Keratosis (LPLK) is a skin condition that affects the outer layer of your skin. It is characterized by small, raised bumps on the skin’s surface, which can be itchy and uncomfortable. LPLK can occur in various forms, and its severity can vary from person to person.
Types of Lichen Planus-Like Keratosis
There are different types of Lichen Planus-Like Keratosis, but the most common ones include:
- Classic Lichen Planus-Like Keratosis: This type is characterized by flat, reddish-brown patches with a scaly texture on the skin.
- Verrucous Lichen Planus-Like Keratosis: In this type, the patches are thicker and have a warty appearance.
- Hypertrophic Lichen Planus-Like Keratosis: These patches are raised, and they can be itchy and painful.
- Lichenoid Lichen Planus-Like Keratosis: This type resembles lichen planus, with purple or violet-colored bumps.
- Pigmented LPLK: It manifests as dark, discolored patches on the skin and may resemble other pigmented skin conditions.
- LPLK with Atypical Features: In this variation, the lesions have unusual characteristics that might require closer examination.
Causes of Lichen Planus-Like Keratosis:
- Unknown Factors: The exact cause of LPLK remains unclear, but it may be related to immune system issues.
- Genetic Predisposition: Some people may be more genetically susceptible to developing LPLK.

Diagnostic Tests for Lichen Planus-Like Keratosis:
- Clinical Examination: A dermatologist will examine your skin and ask about your medical history.
- Biopsy: A small sample of skin may be taken and examined under a microscope to confirm the diagnosis.
- Patch Testing: To identify potential allergens or irritants, patch testing may be conducted.
- Blood Tests: Blood tests can help rule out underlying conditions, such as hepatitis.
- Dermoscopy: This non-invasive technique uses a special magnifying instrument to examine skin lesions.
- Wood’s Lamp Examination: A Wood’s lamp emits ultraviolet light to highlight certain skin features.
- Oral Examination: For suspected oral LPLK, a dentist or oral specialist may conduct an oral examination.
- Imaging: In rare cases, imaging tests like ultrasound or MRI may be used to assess deeper skin layers.
