Keratocarcinoma (Cancer of the Cervix)
The word “kerato” means “cavity”. The term “cancer” refers to any type of cell or tissue that grows out of its original place.
A cancerous tumor is one which has spread beyond the normal limits of its own body. A cancer is usually found when it causes damage to other parts of the body.
A cavity is a hollow space inside another object such as a door, window frame or chest wall.
Keratocanthoma is a slow-growing skin cancer that usually affects the face and appears as a red, pearly or yellowish growth on your skin.
Keratoacanthoma is a form of non-melanoma skin cancer. It is sometimes called a squamous cell carcinoma in situ.
The cause of most cases of squamous cell carcinoma in situ is unknown. It can be thought of as an early form of squamous cell carcinoma, a more advanced form of the same condition.
Squamous cell carcinoma in situ is a skin growth that looks like cancer, but has not invaded deeply into the skin. It can occur anywhere in the skin, but most often appears on the limbs and the face .
This type of tumor is not likely to spread (metastasize) to other parts of your body.
Squamous cell carcinoma in situstends to grow very slowly. However, unless it is treated, it may eventually develop into a more serious form of skin cancer.
Keratosis is the term used to describe the presence of small skin growths that are not necessarily cancerous. They are very common, and may be caused by any of a wide number of factors.
Keratoacanthoma is quite rare, affecting less than one person in a million. While it is generally considered to be a type of squamous cell carcinoma, it does have certain distinguishing features of its own.
Keratomas are non-cancerous tumors. They are not infectious, and do not metastasize.
They are very common, and may appear at any age.
Keratosis pilaris is a type of keratosis that causes small, hard bumps to appear on the upper arms and thighs. These bumps are commonly mistaken for goosebumps.
Kaposi’s sarcoma is a form of skin cancer caused by an abnormal growth of blood vessels. It is most commonly found in people with a compromised immune system, such as those who suffer from HIV or AIDS.
Kaposi’s sarcoma is most commonly found on the skin, but may also appear in the mouth, GI tract or lungs. It is most commonly found in people with a compromised immune system, such as those who suffer from AIDs.
Kaposi’s sarcoma tends to appear as purple or blue-red patches on the skin. These patches may be raised or flat, and may be of any size.
Kaposi’s sarcoma typically appears in middle-aged or elderly people (most commonly those between the ages of 30 and 50).
Kaposi’s sarcoma is a type of cancer that occurs due to problems with blood vessels. It affects men and women in almost equal numbers, and most commonly appears on the skin.
Kaposi’s Sarcoma is a cancer that affects the skin, and most often occurs in people with a weakened immune system.
The cause of erythema is loss of flexibility in the top layer of the skin. This can be caused by excessive sun damage or by other factors such as smoking.
Erythema is a medical term that describes redness of the skin. While it can be harmless in many cases, it can be a sign of a more serious condition.
Erythroderma is a skin condition in which red patches cover most of the body. The patches may be dry or moist, and may be itchy or sore.
Eosinophilic pustular dermatosis is a skin condition in which the skin becomes inflamed and filled with fluid. It is very itchy, and is most common in children.
Eosinophilic pustular dermatosis causes microscopic blisters filled with fluid to appear on the skin. The exact cause of this condition is unknown.
Eosinophilia is an excessive amount of eosinophils in the blood. Eosinophils are a type of white blood cell that fights infection and disease.
Eosinophilia is not usually a cause for concern unless it is accompanied by other signs or symptoms.
Eosinophilia often has no cause, and is not a serious condition. It can be a temporary response to an allergic reaction of some sort.
Eosinophilia can also be a side effect of certain drugs, such as those used to treat asthma.
Eosinophilia is usually the result of an allergic reaction, or by a drug being taken.
Encephalitis is an inflammation of the brain that is caused by a virus. It can cause drowsiness, difficulty with thinking, and even coma.
Encephalitis can be caused by a virus, or it can be caused by a number of different bacteria or parasites.
Encephalitis is most commonly caused by the herpes simplex virus.
Encephalitis is a swelling of the brain that is caused by an infection.
Eczema is a skin condition that causes dry, red, itchy skin. There are many different types of eczema, including atopic dermatitis and allergic contact dermatitis.
Eczema is not a single condition but rather a group of related conditions that cause the skin to become inflamed. It affects people of all ages, but is most common in early childhood.
Eczema may be the result of an allergic reaction to something, such as a specific food or material.
Eczema may be caused by a reaction to a virus or bacteria.
Ebola hemorrhagic fever is a disease that affects the blood, and is often fatal. The disease is transmitted through contact with bodily fluids.
Ebola hemorrhagic fever is a severe illness that affects the immune system and other parts of the body. It is fatal in up to 90% of cases.
Ebola is a rare but deadly disease that is currently affecting several African countries.
Echinococcosis is a condition in which a type of tapeworm called Echinococcus infects the body. The tapeworms can affect many different parts of the body, including the liver, lungs, and brain.
