Kaposi’s sarcoma: originates in the dermis but can also occur in internal organs.

Kaposi’s sarcoma in two forms:
The one that usually develops in people infected with the acquired immunodeficiency syndrome (AIDS) and children and young people of equatorial Africa. This form grows very fast and usually affects the internal organs.

Before the onset of the disease, tended to present only the elderly of European origin Mediterranean. In these people grows very slowly on the skin and rarely spreads.

In the first the characteristic appearance is a sin pink, red or purple, round or oval shape, anywhere in the body but more often in the face.

In the latter usually appears as a purplish stain or dark brown on the legs or toes. Tends to increase its depth, causing a bleeding ulcer. You can also spread up the leg.

Cutaneous lymphoma, occurs when skin cells (cells of the immune system or defense) become malignant. The dermis contains a considerable number of lymphocytes. The most common of these is the cutaneous T-cell lymphoma or mycosis fungoides.

It develops over many years, very slowly. In the initial stages, you may notice itchy skin and dark areas and provide dry. When the disease has developed is called mycosis fungoides.

This disease can spread through the lymphatics to other organs such as lung, liver, etc.. The sooner the diagnosis is made, the greater the likelihood of cure.

Melanoma skin cancer

This disease develops in the melanocytes, skin cells that produce the melanin that gives color. Melanocytes are found in the epidermis layer of outer skin.

Melanoma is the type of skin cancer less common and more serious. You can easily spread to other parts of the body through blood or lymphatic system. If diagnosed early, the prognosis is better.

It can occur from existing moles, or a newly formed, small, pigmented, appearing in an area of normal skin.
We will have to consult the doctor whenever it is noticed a change in the size, shape or color of a mole. Or a mole that is swollen or sore to the touch or oozing or bleeding.

Squamous cell carcinoma (or squamous cell carcinoma) develops in the middle layers of the epidermis and accounts for 20% of all cases of skin cancer.

Usually occurs in areas that have been exposed to the sun, like the top of the nose, ears, forehead, upper lip and backs of hands.

You can also occur in areas of skin that have been in contact with chemicals that have undergone radiotherapy, or have been burned. In the genital area, appears less frequently.

Usually occurs usually a red bump and drive. Sometimes it may look, scaly, or bleed and develop a scab that never heals. As you have enlarged nodular and sometimes presents a warty surface. In the end, it becomes an open sore and growing into the underlying tissue.

Through the lymph system can extend to any body part, but this happens rarely. It is a tumor with a tendency to grow and be on the same site, once removed. But it tends to spread.

Basal cell carcinoma is the most common type of nonmelanoma skin cancer. About 75% of all skin cancers are basal cell carcinomas.

Subsequent to the bottom layer of the epidermis, consisting of basal cells. And usually occurs in areas that have been exposed to the sun, like the head and neck.

It grows slowly and rarely spreads to other parts of the body so it is less aggressive than squamous cell carcinoma. Although not for that we must stop treating it as if nothing is done, over time, will spread to surrounding tissues.

It looks like this is a minor bump with a smooth and shiny appearance. But it can be shaped scar, still firm to the touch. Usually develops slowly although the rate varies from one to another.

It is not uncommon to reappear once the person has been treated. 35% to 50% of those diagnosed will develop a new skin cancer within five years from first diagnosis.

Skin cancer is a disease caused by the development of cancerous cells in any of the layers of the skin.

There are two types: non-melanoma and melanoma.

The non-melanoma cancer is the most common and is called nonmelanoma because they formed from other skin cells are not accumulating pigment (melanocytes). Within this type are all skin cancers less malignant melanoma is less common and more malignant and explained below.

Skin cancer is most prevalent among white skinned people who have spent much time exposed to sunlight, especially when sun exposure occurred in childhood and there were numerous sunburn. Although it may appear anywhere on the skin, is more common than is presented on the face, neck, hands and arms.

This cancer is one of the most common of all cancers, and diagnosed an estimated two million new cases per year worldwide.

In recent years, the incidence of malignant melanoma has increased dramatically, has multiplied by 3.3 in males and 2.5 in women over the last twenty years in Spain. Despite this, less than 3% of all tumors and early detection campaigns have allowed the mortality is reduced by 30% since the seventies.

You can recognize a change in the appearance of the skin, like a wound that does not heal or a small bump. You may also see a red, rough or scaly skin with a tendency to grow.

Any changes or abnormality of the skin, one must see the doctor. It can extract and analyze a sample (biopsy) to check whether a tumor is malignant or not.

The most common cause of skin cancer is sunlight, but there are also environmental factors like pollution, not forgetting the genetic predisposition.

They indicated that this condition usually affected farmers, or people whose type of work spent time under the sun, now the problem is more widespread, changes in behavior (people going to the beach to swim but not tanning) .

They explained that skin cancer usually produces no symptoms, so it is important to be aware of any injuries or stain and pay attention to your moles, especially those that are asymmetrical, as well as those with a diameter greater than one centimeter and changes in its tonality.

Dermatology specialists reported that 5% of patients who attend this service have some type of skin cancer, the most obvious manifestation being basal cell carcinoma (malignant skin tumor).

Say no to skin cancer

Recommendations to prevent skin cancer, cited the use of sunscreen, clothing that covers most of the body, stay away from the sun when the radiation is strongest (between 10:00 and 17:00 hours).

Also avoid sunlamps and tanning beds because they are so damaging as the sun.

All people are affected by exposure to sun, but the most susceptible are children and people with white faces, they concluded.

Solar radiation causes premature skin aging, allergies, cancer, and are also responsible for the long term, according to recent scientific discoveries of the genetic alterations or mutations in DNA.
