If you've noticed small, rough, scaly patches on your skin that won't go away, you might be dealing with lichen keratosis. While the name might sound unfamiliar—or even a bit alarming—understanding this common skin condition can help you make informed decisions about your care.
Lichen keratosis is a term that's sometimes confused with other skin conditions, particularly seborrheic keratosis and lichen planus. In fact, "lichen keratosis" isn't a standard medical diagnosis on its own, but rather describes a group of skin changes that share similar characteristics: thickened, scaly patches that can appear on various parts of your body.
Whether you're concerned about a new skin growth or you've been living with these patches for years, you deserve clear answers. This comprehensive guide will help you understand what lichen keratosis really is, when it requires treatment, and when simple observation is the best approach.
The term "lichen keratosis" isn't typically used as a standalone diagnosis in dermatology. Instead, it's a descriptive phrase that combines two key features:
When healthcare providers use this term, they're usually referring to one of several specific conditions:
Skin growths that fall under the lichen keratosis umbrella are extremely common, especially as you age. Seborrheic keratoses, for example, affect more than 80% of people over age 50. These benign growths are so widespread that dermatologists often call them "barnacles of aging."
Lichen planus-like keratosis is less common but still affects a significant number of adults, typically appearing in middle age or later.
You're more likely to develop these skin changes if you:
Seborrheic keratosis is the most common type of growth that might be called "lichen keratosis." These are:
✅ Completely benign (non-cancerous)
✅ Waxy or scaly in appearance
✅ Brown, black, or tan in color
✅ Stuck-on looking, as if they could be scraped off
✅ Variable in size, from a few millimeters to several centimeters
These growths typically appear on the chest, back, face, and scalp. They're sometimes called "wisdom warts" or "age spots," though they're not related to warts or caused by sun damage.
LPLK represents a unique inflammatory reaction, often occurring when a pre-existing sun spot (solar lentigo) undergoes immune-mediated changes. Key features include:
The good news? LPLK is also benign and often resolves on its own over several months.
This is essentially another name for LPLK, emphasizing the "lichenoid" (lichen-like) pattern seen under the microscope. The terms are often used interchangeably in medical literature.
One of the most important reasons to see a healthcare professional about any skin change is to rule out more serious conditions. Here's how lichen keratosis differs from look-alikes:

While lichen keratosis is benign, you should seek prompt medical evaluation if any skin growth shows these features (remember the ABCDE rule for melanoma):
Additional red flags include:
The exact causes vary depending on the specific type of growth, but several factors contribute:
Family history plays a significant role. If your parents or siblings have numerous seborrheic keratoses or similar growths, you're more likely to develop them too. This suggests an inherited tendency toward these benign skin changes.
As your skin ages, cells can accumulate and form thickened areas. The natural turnover of skin cells slows down, and keratinocytes (skin cells) can cluster together, creating the raised, scaly patches characteristic of lichen keratosis.
While seborrheic keratosis isn't directly caused by sun damage, sun exposure contributes to other types like lichen planus-like keratosis. UV radiation can trigger inflammatory changes in existing sun spots, leading to the lichenoid reaction.
Some researchers believe that lichen planus-like keratosis represents your immune system's response to damaged skin cells. The body recognizes sun-damaged cells and mounts an inflammatory response to eliminate them—a kind of "self-healing" process.
Pregnancy and hormonal fluctuations can sometimes trigger the development of seborrheic keratoses, suggesting that hormones may influence their growth.
Lichen keratosis can vary widely in appearance, but common features include:

Most people with lichen keratosis experience:
✔️ No symptoms at all (asymptomatic)
✔️ Occasional itching (especially with LPLK)
✔️ Irritation from clothing rubbing against raised areas
✔️ Cosmetic concerns if located on visible areas

Your doctor may recommend a skin biopsy if:
A biopsy is a minor procedure that involves removing a small sample of skin for microscopic examination. At The Minor Surgery Center, we perform biopsies quickly and comfortably, with local anesthesia to minimize discomfort.
Depending on the situation, your doctor might use:
The tissue is then examined by a pathologist who can definitively identify the type of growth and rule out any concerning features.
Not every skin growth requires treatment. In fact, for many cases of lichen keratosis, simple observation is the most appropriate approach.
You can safely monitor your lichen keratosis if:
✅ It's been confirmed as benign by a healthcare professional
✅ It's not causing any symptoms or discomfort
✅ It's not in a location that's frequently irritated
✅ You're not concerned about its appearance
✅ It's not changing in size, color, or texture
If you and your doctor decide on watchful waiting, follow these guidelines:
1. Perform Regular Self-Examinations
Set a reminder to check your skin monthly. Look for:
2. Take Photographs
Use your smartphone to document the growth. Include:
3. Keep a Skin Journal
Note any observations:
4. Schedule Regular Check-Ups
Even benign growths benefit from periodic professional evaluation. Annual skin checks are recommended, especially if you have:
Skip the "wait and see" approach and seek immediate evaluation if you notice:
🚫 Rapid growth over weeks or months
🚫 Bleeding without trauma
🚫 Ulceration or non-healing sores
🚫 Severe itching or pain
🚫 Dramatic color changes
🚫 Irregular borders developing

Expected Results:
You can't completely prevent lichen keratosis, especially if you have a genetic predisposition. However, you can reduce your risk and minimize new growths with these strategies:
While seborrheic keratosis isn't directly caused by sun damage, protecting your skin from UV radiation helps prevent the development of lichen planus-like keratosis and reduces overall skin aging.
Daily Sun Protection:
☀️ Apply broad-spectrum SPF 30+ sunscreen every day, even when cloudy
☀️ Reapply every 2 hours when outdoors
☀️ Seek shade during peak sun hours (10 AM - 4 PM)
☀️ Wear protective clothing: wide-brimmed hats, long sleeves, UV-protective fabrics
☀️ Use sunglasses that block 100% of UV rays
Healthy skin is more resilient:
Early detection makes a difference:
While you can't change your genetics or age, you can:
It's completely normal to feel concerned or self-conscious about skin growths. Here's how to cope:

Professional Guidance: Consult with a makeup artist experienced in covering skin imperfections for best results.
No. Lichen keratosis refers to benign (non-cancerous) skin growths. However, it's essential to have any new or changing skin growth evaluated by a healthcare professional to rule out conditions that can look similar but are precancerous or cancerous.
Lichen keratosis itself doesn't spread from one area to another. However, you may develop new growths over time, especially if you have a genetic predisposition. Each growth develops independently.
We strongly advise against this. DIY removal carries risks including infection, scarring, incomplete removal, and—most importantly—you'll miss the opportunity for pathological confirmation of the diagnosis. Professional removal is safe, quick, and provides peace of mind.
Coverage depends on your specific insurance plan and the reason for removal:
At The Minor Surgery Center, we provide transparent pricing and can help you understand your coverage. No surprises, just clear information.
Most procedures take 15-30 minutes, including preparation and bandaging. You can typically return to normal activities the same day or the next day.
Recurrence is uncommon when the growth is completely removed. However, you may develop new lichen keratosis in other areas over time. This represents new growth, not recurrence of the treated lesion.
This is a critical distinction:
They can look similar, which is why professional evaluation is essential.
Most people develop these growths after age 40, with increasing frequency as you get older. However, they can appear in younger adults, especially with certain genetic predispositions.

Lichen keratosis encompasses several types of benign skin growths that are extremely common and rarely cause problems. Understanding the difference between these harmless growths and potentially serious conditions is crucial for your peace of mind and health.
1. Get Professional Diagnosis
Never assume a skin growth is benign without professional evaluation. A simple examination can provide definitive answers and rule out concerning conditions.
2. Choose What's Right for You
Whether you opt for watchful waiting or treatment, make an informed decision based on:
3. Monitor Regularly
Even benign growths benefit from periodic observation. Stay vigilant for changes and maintain regular skin checks.
4. Seek Expert Care
When you decide treatment is right for you, choose experienced professionals who make the process simple, safe, and stress-free.
5. Protect Your Skin
While you can't prevent all skin changes, sun protection and good skin care support overall skin health and may reduce some types of keratotic growths.
Living with lichen keratosis doesn't have to be stressful or confusing. Armed with accurate information, you can make confident decisions about whether to watch or treat these common skin growths.
Remember:
✅ Most lichen keratosis is completely harmless
✅ Professional diagnosis is essential for peace of mind
✅ Treatment is available when you want or need it
✅ Observation is perfectly acceptable for asymptomatic growths
