Has anyone ever heard of a ..

I can't remember the first word but it looks and feels like small round rough patches on the surface of my skin, worse on my legs, ankles and top of my feet. I also have problems with skin tags on the underside of my upper arms, inside thighs and a few on my back. I am only a few lbs overweight so it's not due to that. My dermatologist told me what it was a couple of years ago and I cannot remember, he's not in practice now. If someone else has this or if you're a derm, I'd love to hear from you.

I had a quick search and found this:

SEBORRHEIC KERATOSIS

A seborrheic keratosis is a benign skin growth that is very common among people over 40 years of age. The growths resemble flattened or raised warts, but have no viral origins and may exhibit a variety of colors, from pink or yellow through brown and black. Because only the top layers of the epidermis are involved, seborrheic keratoses are often described as having a "pasted-on" appearance.

Because the tumors are rarely painful, treatment is not often necessary. There is a small risk of localized infection caused by picking at the lesion. If a growth becomes excessively itchy, or if it is irritated by clothing or jewelry, cryosurgery has been found to be highly effective in their removal. The main danger associated with seborrheic keratoses lies in their resemblance to malignant melanomas, which has sometimes led to a misdiagnosis of the cancerous lesions. If there is any doubt, a skin biopsy will allow a physician to make a correct diagnosis. A mutation of a gene coding for a growth factor receptor (FGFR3), has been found in 40% of seborrheic keratosis.
