Actinic Keratoses (plural of actinic keratosis) describes lesions on the outer skinlayer caused by too much exposure to the ultraviolet rays of sunlight. They are also the beginnings of skin cancer, most often appearing after age 40.
People with fair skin, blond or red hair, and blue or green eyes are most at risk of developing these rough, scaly patches, or keratoses. A history of a sunburn also increases the risk. If not treated, these patches can develop into a more serious form of skin cancer, although this is unusual.
Actinic keratoses most commonly occur on areas of skin that receive lots of sun exposure -- like the face, ears, the scalp of bald men, and the backs of the hands and arms. The lesions may be skin-colored, reddish-brown, or yellowish-tan. They may look like a raised bump, be flat, or may feel like a dry patch of skin. The skin-colored lesions may be noticed more by touch, because they tend to feel like sandpaper.
basal cell carcinoma
Basal Cell Carcinoma is a cancer that grows on parts of your skin that get a lot of sun. It's natural to feel worried when your doctor tells you that you have it, but keep in mind that it's the least risky type of skin cancer. As long as you catch it early, you can be cured.
This cancer is unlikely to spread from your skin to other parts of your body, but it can move nearby into bone or other tissue under your skin. Several treatments can keep that from happening and get rid of the cancer.
The tumors start off as small shiny bumps, usually on your nose or other parts of your face. But you can get them on any part of your body, including your trunk, legs, and arms. If you've got fair skin, you're more likely to get this skin cancer.
Basal cell carcinoma usually grows very slowly and often doesn't show up for many years after intense or long-term exposure to the sun. You can get it at a younger age if you're exposed to a lot of sun or use tanning beds.
Melanocytic Nevi are benign proliferations of melanocytes located at different skin levels. Pigmentation in different shades of brown can range from a brown-yellowish to brown-blackish color; sometimes-as in mature cellular nevi-they can be skin-colored. Some people are at risk of developing melanoma arising in benign melanocytic nevi. These are usually fair skinned with history of sunburn or frequent sun exposure especially during childhood. People at risk commonly develop precancerous nevi called dysplastic nevi. If you are fair skinned with many nevi all over your body, regular screening by a professional dermatologist is recommended to detect and remove any suspicious lesions. Finally, the chapter describes the factors that predict regular skin self-examination and accuracy of the skin self-examination.
A skin tag is a small flap of tissue that hangs off the skin by a connecting stalk. Skin tags are benign and are not dangerous. They are usually found on the neck, chest, back, armpits, under the breasts, or in the groin area. Skin tags appear most often in women, especially with weight gain, and in middle-aged and elderly people.
Skin tags usually don’t cause any pain. However, they can become irritated if anything such as clothing or jewelry rubs on them. They can be easily removed by a simple outpatient procedure without leaving any scars.
Seborrheic keratoses are brown or black growths usually found on the chest and back, as well as on the head. They originate from cells called keratinocytes. As they develop, seborrheic keratoses take on a warty appearance. Seborrheic keratoses are usually only if cosmetic concern and can be easily removed leaving no scars with a simple in office procedure. Sometimes seborrheic keratoses developing in large numbers over the course of a short period may signify systemic disease or cancer. A dermatologist can judge if there’s any risk and refer you for further investigations.
Warts are an infection of the skin caused by the human papillomavirus (HPV). The virus enters the body through a break in the skin, such as a cut. It then forms a rough bump on the surface of the skin. Warts are benign (non-cancerous) growths.Wart viruses are contagious. Warts can spread by contact with the wart or something that touched the wart. People with a weakened immune system are more likely to have warts. The appearance of a wart depends on its location on the body and the thickness of the skin. Treatments include salicylic acid, duct tape, cryotherapy, surgery, laser treatment, electrocautery, photodynamic therapy, chemical treatments, topical creams, cantharidin, and antigen shots. The choice of treatment depends on the type of wart, it’s location and personal preference.
Molluscum contagiosum is a viral skin infection that causes either single or multiple raised, pearl-like bumps (papules) **on the skin. The papules have indentations or dimples in the center.
Molluscum contagiosum is caused by a virus (molluscum contagiosum virus) that is part of the pox virus family. The virus is contagious (able to be spread from person to person) through direct contact and is more common in children. Scratching or rubbing the bumps spreads the virus to nearby skin. It’s not clear if swimming pools can in fact transmit the virus, however probably rubbing against the pool edge and sharing pool related toys and boards can transmit the infection. Although molluscum lesions may disappear on their own, this might take about a year and it is infectious. Treatment options include topical treatment, electrocautery, chemical treatment and freezing.
