There are three main types of scalp lesions that can look like a blister, and this includes cancer.
This is why it’s important to have a dermatologist inspect your scalp on a yearly basis as part of your skin cancer screening.
“A blister-like spot on the scalp could be a blister (will resolve in a couple of weeks or as all blisters do), a non-cancerous growth (like a mole) or a skin cancer,” says Dr. Steven Musick, MD, a board certified dermatologist who runs Musick Dermatology, LLC, in Swansea, IL, which provides state-of-the-art medical and surgical care for all disorders of the skin, hair and nails.
“If the lesion persists, seek evaluation by a qualified dermatologist,” says Dr. Musick.
A type of non-cancerous growth that just might look like a blister is a seborrheic keratosis.
These typically begin appearing after age 40 and can appear anywhere on the body, including the scalp. They can resemble melanoma.
However, a melanoma can sometimes pass as a seborrheic keratosis.
NOT ALL MELANOMAS ARE DARK.
So if you see ANY strange new growth on your scalp – or you’re not sure how long you’ve had a newly-discovered lesion – have a dermatologist examine it.
Another type of growth that can seem like a blister is a strange kind of mole called a dysplastic nevus (atypical mole).
These typically appear in childhood or young adulthood, and can strongly resemble melanoma. And vice versa.
