The Kaposi’s sarcoma is a malignant tumor that can occur especially on the skin, but also on mucous membranes and internal organs such as the bowel. Characteristic are brownish, nodular lesions that usually appear first on the legs. Kaposi’s sarcoma is most common in the context of a weakened immune system (immune-suppression) and infection with the human herpesvirus type 8 (HHV-8). Men are affected often more than women. Who is at risk of Kaposi’s sarcoma? An HIV-infected person has a 20,000 times increased risk of developing Kaposi’s sarcoma as compared to to a person without HIV. In the early 1990’s...

Types of Melanoma
A malignant melanoma or black skin cancer is an aggressive, highly malignant skin tumor that occurs predominantly on areas of the skin that expose to sunlight (e.g. face, neck, arms and lower legs). A malignant melanoma occurs not only on expose parts of the body, but also on other part of skin. In men, skin cancer mainly occur on the trunk (for example on the back), in women mainly forms on arms and legs. Skin cancer may also develop in “hidden parts of the body” such as the feet, the genital area, the scalp or the skin underneath a nail....

Important factors which are responsible for the development of malignant melanoma are strong exposure to UV radiation having recurring sunburns or overall frequent sunbathing and genetic (hereditary) predisposition. The exposure to UV rays can damage the genetic material ( DNA ) of melanocytes. Most of these damaged cells die or be repaired. However, the DNA damage is not completely repaired in some cells and later these cells lead to development of tumor. Excessive exposure to UV radiation weakens the immune system which is important for the defense of malignant cells. Risk factors The risk factors that favor the development of...

Spinaliom or Squamous cell carcinoma is a type of white skin cancer. Squamous cell carcinoma i defined as a malignant skin tumor that can occur on skin and mucous membranes and grows destructively . It is malignant tumor of cells of the Stratum spinosum. If we viewed from the inside out, stratum spinosum (prickle cell layer) is second of the five layers of the epidermis. The epidermis is composed of a multilayered keratinizing squamous epithelium. Accordingly, it is a malignant tumor of this squamous a so we called it squamous cell carcinoma. The squamous cell carcinoma include the cancers of:...

A squamous cell carcinoma is caused by changes in genetic material (DNA) of the skin cells that may have different causes. The main cause is the long-term sun exposure . However, other factors are also responsible for this which can adversely affect the skin and lead to development of Spinaliom squamous cell carcinoma. Risk of squamous cell carcinoma is slightly higher in male than female. This is mainly due to the increased exposure to cancer-causing factors in professions and the preference for pipe smoking (tar). Another cause is the balding in men, which leads to increased UV exposure of formerly...

The basal cell carcinoma (BCC) is a type of white skin cancer and also known as basal cell Skin cancer. Bcc is most common form of skin cancer. It develops from the so-called basal cells at the base of the epidermis. Initially formed a nodule or induration in to the affected area of skin . It tends to occur in areas which are exposed to a stronger sunlight. Accordingly, in 80% of cases basal cell carcinoma found at the head and neck. Rarely tumor growth is induced by arsenic or long-term use of medication which suppress the immune system. The average...

Actinic Keratosis Or Solar Keratosis The actinic keratosis is a specific lesion that produced by ultraviolet rays ( actinic means caused by radiation and keratosis means growth of keration on mucus membrane or on skin ). Since ultraviolet light occurs naturally in sunlight, actinic keratosis is also known as solar keratosis . The actinic keratosis is a skin condition that can develop into squamous cell carcinoma (squamous). Dermatologists also consider actinic keratosis as in-situ carcinoma. Actinic keratosis is understood as an early form of skin cancer that can remain inconspicuous for long years. However, there is also the possibility that...

The causes for the development of colorectal cancer are not yet fully understood. It is now known, however, that several causes are principally responsible for it. In most cases, colon cancer comes from polyps produced. Colon polyps are benign protrusions in the intestinal mucosa. If these polyps degenerate and form cancer cells, colon cancer arises. Who polyps, has an increased cancer risk. Even if close relatives had or have polyps your own risk is increased. These are mushroom-like protrusions of the intestinal mucosa, which grow in the intestinal area. Approximately 90 percent of colon cancers arise because these polyps degenerate,...

Colorectal cancer is also known as Bowel cancer or colon cancer or rectum cancer. Colorectal cancer can generally arise in any part of the intestine: in the small intestine, in the colon or in the anal area. Tumors in the small intestine or in the anal area come much rarer than tumors in the colon, they are also treated differently. Malignant tumors mainly develop from cells of the intestinal mucosa. Depending on which portion of the colon is affected by cancer, doctors distinguish between Rectal cancer and Colon cancer. When the tumor is located in the last section of the...

This is a rare benign tumor, most often occurring in children under 12 years. It represents less than 1% of all brain tumors. In children, the most frequent site of this tumor in the lateral ventricles. Plexuspapillome grow slowly inside the ventricles. They may block the flow of cerebrospinal fluid. This can cause hydrocephalus and increased the intracranial pressure. Papillomas of the choroid plexus are usually congenital neuroectodermal tumors, they make up about 1% of all tumors of the CNS. Most often they are sitting in the lateral ventricles, sometimes they are multiple, often sit in the 3rd ventricle or...
