Seborrheic keratoses are one of the most common non-cancerous skin growths in older adults. Although the growths are benign, they may hide developing skin cancer especially on sun exposed areas.
Although anyone can develop seborrheic keratoses, you may be more likely to develop them if:
- Older than 40 years of age
- Family history of seborrheic keratosis
SIGNS & SYMPTOMS
Seborrheic keratoses are most commonly found on the face, scalp, chest, shoulders and back.
- Round or oval shaped
- Waxy or wart-like growths
- Flat or slightly elevated with a scaly surface
- Characteristic “stuck on” appearance
- Starts as a skin colored growth but may become tan, brown, or black
- Size ranges from very small to very large
- May appear as a single growth or cluster
Seborrheic keratoses may become irritated, itchy and bothersome depending on their size and location. Scratching, rubbing or picking can result in inflammation, bleeding, and rarely infection.
Seborrheic keratoses treatment is not necessary unless they become irritated by your clothes, itchy, bleed or if you just dislike how they look or feel.
- Cryotherapy: liquid nitrogen is used to freeze the seborrheic keratoses. May need to be repeated a few times. However, it may not work on large, thick growths, and may lighten the skin permanently.
- Curettage and Desiccation: which scrape away the growth and uses electricity to remove it.
- Surgical Removal: surgical removal of the seborrheic keratosis if it too thick, or if there is suspicion that pre-cancers or skin cancer may be hiding under the seborrheic keratosis on sun-damaged skin.
