Dr. Shane Chapman, MD discusses Skin Cancer Basal Cell Carcinoma. See more at http://www.dermnet.com PLEASE RATE AND COMMENT!!!
Basal cell carcinoma is not only the most common type of skin cancer, it is also the most common malignancy in humans. Like melanoma, it is more common in fair skin types, but unlike melanoma, it rarely metastasizes.

The most common presenting complaint is a bleeding or scabbing sore that heals and recurs.

Basal cell carcinomas tend to occur on the sun exposed areas of the head and neck, including the nose, ears and scalp. Rarely, a basal cell carcinoma will occur within a scar or other areas of trauma. Unfortunately, in the past there was a tendency to regard BCC as nonmalignant because the tumor rarely metastasizes. BCC advances by direct extension and destroys normal tissue. Left untreated or inadequately treated, the cancer can destroy the whole side of the face or penetrate subcutaneous tissue into the bone and brain. BCC occurs in many different clinical forms.

Via http://www.dermtv.com – We sincerely hope that you wear sunscreen while relaxing at the beach, lounging alongside the pool or doing an activity outside. But do you wear sunscreen every other time you’re outdoors? We’re sure you’ll be able to guess what Dr. Schultz thinks about this and when you should and shouldn’t be wearing sunscreen.

Transcription:
Patients ask me, “Do I really need sunscreen every day?” and the answer is, “Yes.” There are two reasons. Think of your skin as having a meter on the surface. Every time the sun hits it, its starts the meter and the meter runs continuously. Your skin doesn’t know the difference between walking to work for five minutes in each direction every day, five days a week, which is ten minutes a day, 50 minutes a week. Your skin doesn’t know the difference between those 50 minutes a week of unprotected sun protection and being out on the beach for 50 minutes continuously on Saturday. That’s the first reason. The second reason has to do with the fact that, if you can see your hand in front of your face when you go outside, then there is enough light coming through the clouds, even if it’s a cloudy day, to bring some of the ultraviolet light with it, and that ultraviolet light is hitting your skin. Certainly not the same way it does on a sunny day, but you’re still getting that ultraviolet burning and damaging sun. So, for both of those reasons, please use a sunscreen everyday and choose one that has an SPF between 15 and 30.

Dr. Shane Chapman, MD discusses Skin Cancer Squamous Cell Carcinoma Appearance. See more at http://www.dermnet.com PLEASE RATE AND COMMENT!!!
SCCs arising from actinic keratoses may have a thick, adherent scale. The tumor is soft and freely movable and may have a red, inflamed base. These lesions are most frequently observed on the

bald scalp, forehead and backs of the hands. Cutaneous horns may begin as actinic keratoses and degenerate into SCC.

SCCs originating on the lip or from apparently normal skin are

aggressive and metastasize to the regional lymph nodes and beyond.

Those SCCs beginning in actinically damaged skin, but not from actinic keratoses, appear as firm, movable, elevated masses

with a sharply defined border and little surface scale.

The potential for SCCs to metastasize is related to the size, location, degree of differentiation, histologic evidence of perineural

involvement, immunologic status and depth of invasion. SCCs that arise in actinically damaged skin were previously thought to have a minimal potential for metastasis; however, such lesions

may be aggressive. SCC first metastasizes to regional lymph nodes in the majority of cases.

Dr. Shane Chapman, MD discusses Skin Cancer Nodular Basal Cell Carcinoma. See more at http://www.dermnet.com PLEASE RATE AND COMMENT!!!
Nodular BCC is the most common form. The lesion begins as a pearly white or pink, dome-shaped papule resembling a molluscum contagiosum or dermal nevus. The mass extends peripherally. The lesion may remain flat. Traction on the surrounding skin accentuates the pearly border. Telangiectatic vessels become prominent and easily recognizable through the thin epidermis as the lesion enlarges. The growth pattern is irregular, forming an oval mass and the surface may become multilobular. The center frequently ulcerates and bleeds and subsequently accumulates crust and scale. Ulcerated BCCs were formerly designated rodent ulcers.

Ulcerated areas heal with scarring, and patients often assume their conditions are improving. This cycle of growth, ulceration, and healing continues as the mass extends peripherally and deeper. Masses of enormous size may be attained.

BCCs may present as nonhealing leg ulcers. Biopsy specimens should be taken of leg ulcers that do not respond to treatment. The tissue mass of a nodular BCC has a distinctive consistency that can be appreciated during curettage or biopsy. It has poor cohesive forces and collapses or breaks down when manipulated with a curette. This is an important diagnostic feature that supports the clinical impression during the biopsy procedure.
