Has anyone ever heard of a skin disorder with two words, last one being Keratosis?

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.

Has anyone ever heard of a skin disorder with two words, last one being Keratosis?
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.





I also found SOLAR KERATOSIS


What is a solar keratosis?





A solar keratosis is a small, rough, bump which develops on the skin. It is caused by a lot of exposure to the sun over many years. One or more may develop. It is sometimes called an actinic keratosis.





What does a solar keratosis look like?





Each one can range from the size of a pinhead to 2-3 cm across. Their colour can be light, dark, pink, red, the same colour as your skin, or a combination of these. The top of each one may have a yellow-white crust. They feel rough and dry, and are slightly raised from the surface of the skin. You can often feel them more easily than see them. Some redness may develop in the surrounding skin.





Sometimes a finger-like growth of hard skin appears to come out of a solar keratosis (a 'cutaneous horn').





Several solar keratoses may develop at about the same time, often in the same area of skin. Sometimes several join together and form a large flat-ish rough area of skin.





Solar keratoses usually develop on areas of skin which have been exposed to the sun a lot. For example, on the face, neck, bald patches on the scalp, and the backs of the hands. They may appear in other areas in people who do a lot of sunbathing.





There are usually no other symptoms. Rarely, you may get an itchy or pricking sensation from affected areas of skin.





I hope that these help
Reply:Yes i do ! CERATOSIS NIGRICANS in Latin.
Reply:Maybe Actinic keratosis? A precancerous skin growth usually caused by sun exposure.
Reply:Actinic Keratosis
Reply:There are three types of keratosis. First, there is actinic keratosis (also known as solar keratosis), which is a premalignant condition of thick, scaly, or crusty patches of skin. It is most common in fair-skinned people who are frequently exposed to the sun, because their pigment isn't very protective. It usually is accompanied by solar damage. Since some of these pre-cancers progress to squamous cell carcinoma, they should be treated.





When skin is exposed to the sun constantly, thick, scaly, or crusty bumps appear. The scaly or crusty part of the bump is dry and rough. The growths start out as flat scaly areas, and later grow into a tough, wart-like area.





An actinic keratosis site commonly ranges in between 2 to 6 millimeters, and can be dark or light, tan, pink, red, a combination of all these, or the same pigment of ones skin. It may appear on any sun-exposed area, such as the face, ears, neck, scalp, chest, back of hands, forearms, lips etc.








Second, there is seborrheic keratosis. Seborrheic keratosis are other bumps that appear in groups like the actinic keratosis but are not caused by sun exposure, and are not related to skin cancers. Seborrheic keratosis may be mistaken for an actinic keratosis. This 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 keratosis 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.

A mutation of a gene coding for a growth factor receptor (FGFR3), has been found in 40% of seborrheic keratosis.





Third, there is, Keratosis pilaris (KP), which is a very common genetic follicular condition that is manifested by the appearance of rough bumps on the skin and hence colloquially referred to as "chicken skin". It most often appears on the back and outer sides of the upper arms (though the lower arms can also be affected), and can also occur on the thighs and tops of legs, flanks, buttocks or any body part except glabrous skin (like the palms or soles of feet). Less commonly, lesions appear on the face and may be mistaken for acne. Keratosis pilaris occurs as excess keratin, a natural protein in the skin, accumulates within the hair follicles forming hard plugs (process known as hyperkeratinization). Bearing only cosmetic consequence, the condition most often appears as a proliferation of tiny hard bumps that are seldom sore or itchy. Though people with keratosis pilaris experience this condition year round, it’s during the colder months when moisture levels in the air are lower that the problem can become exacerbated and the “goose bumps” are apt to look and feel more pronounced in color and texture. Many KP bumps contain an ingrown hair that has coiled. This is a result of the keratinized skin "capping off" the hair follicle, preventing the hair from exiting. Instead, the hair grows inside the follicle, often encapsulated, and can be removed, much like an ingrown hair, though can lead to scarring.





Your case is similar to all three, so I hope this helps.
