3. Scaly Surface
Melanoma has a different texture to its surface when compared with seborrheic keratosis lesions. The growths from the development of seborrheic keratosis often have a scaly surface that feels rough to touch.
As you rub your finger along the length of the lesion, you’ll notice that it feels like you could pick it off of your skin. However, it’s best not to irritate the growth as you may aggravate it and cause further growth and spread of the lesion.
Seborrheic keratosis growths typically stand proud of the skin. In some cases, the lesions look like clusters of warts, creating a dry and rough surface. If you trace your finger over the growth, you may feel a waxy texture.
It’s important to note that the lesions may occur anywhere on the body, except for the palms of the hands and soles of the feet. It’s also unusual for the growths to pop up on the back of the knees and the armpits.
