Quick summary: Seborrheic keratosis is a common, usually harmless skin growth that can look waxy, scaly, brown, tan, or black. Because it can resemble other skin lesions, a new, changing, bleeding, or painful spot should be checked by a clinician.
Medical disclaimer: This article is for general information only and is not a diagnosis. If you are unsure about a skin spot, or if it changes, bleeds, crusts, or becomes painful, seek advice from a qualified healthcare professional.
What is seborrheic keratosis?
Seborrheic keratosis is a common, non-contagious skin growth. It is usually benign, which means it is not cancerous. These growths often appear as raised spots or plaques with a waxy, scaly, or rough surface.
They can vary in color and may look brown, tan, black, or sometimes lighter. Seborrheic keratosis often appears on the face, chest, back, or scalp, and it may become more noticeable with age.
People often search for a picture of seborrheic keratosis to compare the appearance of a spot on their own skin. Images can be helpful for general awareness, but they cannot confirm a diagnosis.
What does seborrheic keratosis look like?
Seborrheic keratosis can have several common visual features:
- Color: Brown, tan, black, or mixed shades.
- Texture: Waxy, scaly, rough, or slightly stuck-on in appearance.
- Shape: Round, oval, or irregular.
- Size: Small spots or larger growths.
- Location: Often on the face, scalp, chest, back, or in skin folds.
Some lesions appear suddenly, and more than one may develop over time.
Common symptoms and features
Seborrheic keratosis is often noticed because of how it looks rather than because it causes symptoms. In some cases, it may become itchy, irritated, or catch on clothing.
Features people commonly notice include:
- Raised or slightly elevated skin growth
- Scaly or waxy surface
- Color variation from light brown to dark brown or black
- One lesion or several lesions
What causes seborrheic keratosis?
The exact cause is not fully understood. The condition is more common with age, and genetics may play a role. Sun exposure may also affect how visible the lesions are, although it is not described as a direct cause in the original content.
Who is more likely to develop it?
Certain factors may make seborrheic keratosis more likely:
- Age: It becomes more common as people get older.
- Family history: It may run in families.
- Skin type: It may be more common in lighter skin types.
- Immune system: People with weakened immune systems may notice more lesions.
When should you see a doctor?
It is sensible to have a skin lesion checked if it:
- Becomes painful or itchy
- Changes in size, shape, color, or texture
- Bleeds or crusts over
- Looks different from other spots on your skin
Because seborrheic keratosis can resemble other skin conditions, a healthcare professional may examine it closely and, if needed, suggest further assessment.
How is it treated?
Seborrheic keratosis often does not need treatment. If removal is desired, a clinician may discuss options such as:
- Cryotherapy: Freezing the lesion with liquid nitrogen
- Curettage: Scraping the growth off
- Electrosurgery: Using electric current to remove the lesion
The best approach depends on the lesion, its location, and the clinician’s assessment.
Can home remedies help?
Some people try home remedies, but the original content notes that results vary and that no home remedy has been conclusively proven effective. Examples sometimes mentioned include aloe vera, castor oil, and apple cider vinegar.
These products may irritate the skin, so it is wise to be cautious and to ask a healthcare professional or pharmacist before trying anything on a suspicious lesion.
Can seborrheic keratosis be mistaken for skin cancer?
Yes. Seborrheic keratosis can sometimes look similar to skin cancer or other skin growths. That is why a professional evaluation matters if there is any uncertainty.
Features that can raise concern include:
- Asymmetry
- Multiple colors
- Bleeding or crusting
If a spot is new, changing, or unusual, it should be assessed rather than assumed to be benign.
What people often want to know from pictures
Images can help you understand the general appearance of seborrheic keratosis, including how it may look on the scalp, face, chest, or back. However, photos cannot replace an in-person examination, especially when a lesion is changing or looks atypical.
Safety reminder
Do not try to remove or treat a suspicious skin lesion at home if you are unsure what it is. Avoid picking, cutting, or using harsh products on the area. If in doubt, have it checked by a qualified clinician.
