Raised red, scaly patches of skin on your elbows, knees, scalp, or neck may be a sign of psoriasis. The National Psoriasis Foundation states that this autoimmune disorder may be triggered by stress, injury, or infection. Furthermore, certain medications such as lithium, antimalarial drugs, beta-blockers, or quinidine may trigger flares of psoriasis. Current treatments for psoriasis include corticosteroids, vitamin D analogs, anthralin, and topical retinoids. Light therapy, biologic agents, immune system suppressants, and methotrexate also help to treat psoriasis.
4. Seborrheic Keratosis
Seborrheic keratoses are skin growths that are tan, brown, or black in appearance and may resemble either a wart or a waxy deposit. Unlike actinic keratoses, these growths are not cancerous. The American Academy of Dermatology lists genetic predisposition and sun exposure as risk factors for this condition. Your dermatologist may remove a seborrheic keratosis if it resembles skin cancer, catches on clothing or jewelry, or is irritating. If the growth looks like skin cancer, your doctor may remove it and send it to a pathologist.
3. Skin Tags
Skin tags are soft, tiny, flaps of skin that may appear on your neck or in areas of the body where skin rubs together or against clothing. These include areas such as eyelids, armpits, and groin. While many do-it-yourself remedies have cropped up on the internet, these solutions may result in bleeding and infection. Skin tags are noncancerous. However, they may cause discomfort and irritation as they rub against clothing or become caught on clothing or jewelry. Medical News Today recommends seeing a dermatologist or other skin specialist if you desire skin tag removal.
