Cutis rhomboidalis nuchae refers to the manifestation of long-term, prolonged sun exposure and resultant damage to the skin occurring on the back of the neck. Long-term, chronic sun exposure causes thickening of the most superficial layer of the skin (the epidermis) and abnormalities in the composition of the middle layer of the skin (the dermis).
Poikiloderma of Civatte is a chronic, non-cancerous (benign) skin condition in fair-skinned adults, which is probably caused by long-term sun exposure. Poikiloderma of Civatte shows a specific pattern of color change in the skin due to sun damage to the neck and sometimes the center of the chest.
Actinic keratoses, also known as solar keratoses, are small rough or scaly areas of skin due to damage from sun exposure. Some actinic keratoses can turn into squamous cell skin cancer, so it is important to perform self-examinations often and catch them early.
Milia are common, normal skin findings that look like tiny white bumps, usually on the face. They can occur in people of all ages but are most common in newborn babies, where they appear on and around the nose. In teens and adults, they are commonly found on the cheeks and around the eyes. Milia are formed when the top layer of skin does not shed normally but instead becomes trapped in a tiny pocket on the surface of the skin. This is similar to how some acne forms, but milia are not inflamed like acne, and treating milia with acne therapies will only irritate the skin. Your doctor can help you differentiate between acne and milia and can recommend proper treatment.
Keratoacanthoma (KA) is a rapidly growing skin cancer usually appearing as a volcano-like bump on the sun-exposed skin of middle-aged and elderly individuals. Many scientists consider keratoacanthoma to be a less serious form of squamous cell carcinoma. Most keratoacanthoma cause only minimal skin destruction, but a few behave more aggressively and can spread to lymph nodes.
Actinic cheilitis, sometimes known as "farmer's lip" or "sailor's lip," is a precancerous condition related to cumulative lifetime sun exposure. The lower lip is most often affected. Individuals with actinic cheilitis often complain of persistent dryness and cracking of the lips. They will frequently exhibit other effects of sun-damaged skin, such as precancerous lesions on the skin called actinic keratoses and extensive wrinkling.A certain type of skin cancer (squamous cell carcinoma) develops in 6–10% of cases of actinic cheilitis.
Bruises (contusions) are dark, discolored areas on the skin that form when blood seeps into surrounding tissue beneath the skin, often due to a bump or hit to the body.Bruises do not always occur at the exact site of the trauma, as gravity can cause them to appear in another location.Bruises can be a sign of internal bleeding.First Aid GuideIf there is external bleeding in addition to bruising, attempt to stop the bleeding before attending to the bruising. General measures for stopping bleeding are as follows:Locate the source of the bleeding. Wash your hands and, when possible, wear gloves or use a barrier between you and the wound. Remove any loose debris. Note: Do NOT pull debris from a wound that is embedded. With a sterile or clean dressing, apply direct pressure. Unless a broken bone is suspected, elevate the injured area above the heart.If the bleeding does not stop after 15 minutes of the above measures, seek prompt medical care.Self-care measures for bruises are as follows:Apply a cold compress to the affected area to reduce the swelling. Note: Do not put ice directly on the skin. Cold compresses can be applied for 30–60 minutes a day until the bruising subsides. If the bruise is on an extremity (eg, arm or leg), raise it above the heart to reduce the flow of blood to the affected area.Take a pain reliever (eg, acetaminophen, Tylenol®) for pain, if needed.
Squamous cell carcinoma (SCC) is the second most common form of skin cancer. Squamous cell carcinoma usually occurs on sun-damaged skin, especially in light-skinned individuals with a long history of chronic sun exposure.Squamous cell carcinoma requires treatment to prevent it from becoming too invasive. If it is caught early and treated appropriately, squamous cell carcinoma rarely spreads (metastasizes) to lymph nodes or to internal organs. However, if it is neglected, squamous cell carcinoma can cause tissue destruction or it may spread internally, causing serious health problems and even death.
Many dermatology patients will undergo a skin biopsy at some point during their lives, especially if they have a new lesion that could potentially be a skin cancer. During a biopsy, a sample of body tissue is taken so that a type of doctor, known as a pathologist, can examine the individual cells in the tissue under a microscope in order to make a more definitive diagnosis.
So summer is almost over… and we are left with glowing tans and bikini lines that we could show off for maybe a few weeks after that awesome beach trip.
I've never had a skin cancer, but I've had a lot of sun damage and burns in the past. Should I see a dermatologist?
The summer is a great time to enjoy the sun and get some extra Vitamin D but it’s also a time when we sunburn the most. Not only can we get sunburn from a being outside on a sunny or cloudy day but we can also get burned from tanning salons. It’s the UV light from the sun and the tanning beds that gives us the tan and the burn. So what can we do about it?
Spend a day at the beach or pool, and you can’t miss the pervasive and unmistakable smell of sunblock products wafting through the air. Shelves in drug stores and supermarkets are crowded with “new and improved” potions, lotions, gels, creams, wipes, and sprays. But using sunblock only on beach or pool days isn’t enough. Make it an everyday habit – and not just a quick smear on your nose in the morning.
With summer already here, it's important for everyone to know a little bit more about sunburns. What are they? What can you do to avoid them? And what can you do once you have a sunburn?
Skin cancer is the most common type of cancer found in humans, and greater than half of all new cancers diagnosed are skin cancers. Basal cell and squamous cell carcinomas are respectively the first and second most common forms of skin cancer, and nearly half of all Americans who live to age 65 will be diagnosed with one of these types of cancer. These common cancers are usually found in the most sun-exposed parts of the body, appearing in the skin’s top layer as a scaly area or bump that doesn’t heal. They can occasionally bleed. If detected and treated early, these cancers have a greater than 95% cure rate.
