Dr. Niren on Psoriasis

Psoriasis is a chronic skin condition caused by an overactive immune system. Some of the symptoms include flaking, inflammation, and white, silvery, or red patches on the skin. Psoriasis is usually treated with the help of treatments such as steroid creams, occlusion, light therapy and oral medications, as well as biologics. Unpredictable and irritating, Dr Neil Niren describes psoriasis as one of the most baffling and persistent of skin disorders.


This skin condition is characterized by skin cells that multiply up to 10 times faster than normal. Once the underlying cells reach the skin's surface they die, and their sheer volume causes raised, red plaques covered with white scales. As a certified dermatologist with over 35 years of experience, Dr. Neil Niren MD has a thorough understanding of psoriasis. Typically it manifests on the knees, elbows, and scalp, although it can also affect the torso, palms, and soles of the feet.


There are several types of psoriasis and the symptoms depend of the type you have. The most common variety of the condition includes plaques of red skin covered with loose, silver-colored scales. These lesions can be itchy and painful, and they sometimes crack and bleed. In some severe cases, the plaques of irritated skin can grow and merge into one another, covering large areas.

In terms of what triggers psoriasis, Dr Neil Niren believes it is a combination of genes. In people with psoriasis, the genes that control the immune system signals get mixed up. So, instead of protecting the body from invaders as it's designed to do, it triggers inflammation and turns skin cells on overdrive.


As Neil Niren MD explains, psoriasis is quite often associated with psoriatic arthritis, which leads to pain and swelling in the joints. Those who suffer from this condition know just how difficult and frustrating it can be to treat it. It comes and goes in cycles of remissions and flare-ups over the course of a patient’s lifetime. There is no cure for this condition yet, although there are some medications and therapies that can help clear up the patches of red, thickened skin.

Niren MD: Skin Cancer

Skin cancer is a common, low-grade cancerous growth of the skin. It begins in the skin's top layer, the epidermis and continues to those cells with the potential to reproduce in an out-of-control manner. The epidermis is a thin layer that provides a protective cover of skin cells that our bodies continually shed.

Unlike other cancers, most types of skin cancers have no potential to spread to other parts of the body. However, according to Dr. Neil Niren, an experienced dermatologist, skin cancer is the most common type of cancer in the U.S. More than a million patients are reviewing this condition each year.

There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Melanoma is far less common, though more dangerous, than the other two. According to the Niren, 76,690 Americans, around 60 percent of them men, were diagnosed with melanomas of the skin in the last year. Non-epithelial skin cancers, such as sarcomas, affected another 5,880 people.

Skin cancer usually develops on areas of sun-exposed skin, such as the scalp, face, lips, ears, neck, chest, arms and hands, and on the legs in women. However, it can also occur on areas of your skin that are not normally exposed to sunlight like your palms, beneath your fingernails or toenails, and your genital area

In Neil Niren's knowledge, you can reduce the chances of skin cancer by limiting or avoiding exposure to ultraviolet radiation. Frequent check-ups for suspicious changes can help detect skin cancer at its earliest stage, which gives you the greatest chance for successful skin cancer treatment.

This skin condition affects people of all skin tones, including those with darker complexions. In people with dark skin tones, melanoma is more likely to occur in areas that not normally exposed to the sun.

Skin cancer appears when mutations occur in the skin cells DNA. The mutation then causes the cells to grow out of control and form a mass of cancer cells. Ultraviolet radiation found in sunlight and in the lights used in tanning beds can cause great damage to DNA in skin cells, which can result in skin cancer. Still, Neil Niren MD adds that there are other factors that may contribute to the risk of skin cancer, such as being exposed to toxic substances or having a condition that weakens your immune system.
