1. Harlequin Ichthyosis
TEN is identified as a severe allergic reaction. The allergic reaction is usually in response to an infection or a medication. TEN causes flu-like symptoms over a several day period. Inflamation of the mucous membranes then occurs. A rash covers the skin, killing the uppermost layer of skin. The dead skin will shed. This occurs over 30% of the body and can be fatal. More than a quarter of the people afflicted with this painful condition die from some type of infection.
7. Scleroderma
 
This skin disease afflicts newborn babies. It is a rare skin disease, 
believed to be caused by a gene mutation, which usually results in death
 within two days from birth. Harlequin Ichthyosis or HI causes 
the skin to dry out and from hard plaques shaped like diamonds. When the
 baby is born, the infant appears to be wearing a coat of armor. The 
condition severely restricts the newborn's movements.
HI causes complications which are attributed to the newborns deaths. The
 babies experience feeding problems. These infant are also susceptible 
to both respiratory diseases and bacterial infections. Fortunately, the 
level of care has improved substantially which in turn has increased the
 survival rate for babies born with this devastating skin disease.
2. Epidermolysis Bullosa
Epidermolysis Bullosa is a group of hereditary skin disease. 
There are three major types with several subsets. The skin disease has a
 range of severity. The skin disease causes the skin to blister with only a light torch. Individual with more severe case of Epidermolysis Bullosa with
 suffer with glistering of the mouth and esophagus too. Some types of 
this disease can cause the toes and fingers to fuse giving the 
appearance of webbing. Severe scaring in another effect.
There is no cure for this deadly skin disease. Victims of skin 
conditions have to endure various courses of treatment, dependent on the
 severity of their conditions. Some afflicted with this skin disease 
must obtain food through a feeding tube to prevent infections. Surgeries
 are often performed to dilate the esophagus and to remove the scar 
tissue from the blistering.
3. Ehlers-Danlos Syndrome
Ehlers-Danlos Syndrome is a hereditary conditions. It is caused 
by abnormalities in the collagen. This skin disease causes the skin to 
be extremely stretchy (hyper elasticity) and lax. Persons afflicted with
 Ehlers-Danlos Syndrome will also suffer with tissue weakness and easy bruising. Weak joints are also characteristic of this skin disease.
As with other skin disease, the severity of the symptoms experienced by an individual afflicted with Ehlers-Danlos Syndrome
 depends on the type the person has. Some types of this disease will 
cause hemorrhaging and can result in the rupturing of arteries. An 
occurrence of this type will result in the person's death.
4. Methicillin-resistant Staphylococcus (AKA MRSA)
MRSA is labeled the "super bug". This potentially deadly 
skin infection begins as small red bumps. The bumps look similar to 
pimples or bug bites. These small bumps evolve into deep and painful
 abscesses. The bacteria are confined into the skin but can gain access 
into the body. Once in the body, MRSA causes infections in the blood, 
heart, lungs, bones, and joints.
Treatment options for MRSA include surgery and certain antibiotics.
 Surgery is performed to drain the wounds that become open abscesses and
 place the person at risk for life threatening infections. MRSA is 
resistant to almost all antibiotics. The bacteria have adapted defenses 
to combat what was once a lethal toxin to the infection. Only two 
antibiotics are strong enough to combat MRSA, vancomycin and linezolid.
5. Toxic Epidermal Necrolysis (AKA TEN)
TEN is identified as a severe allergic reaction. The allergic reaction is usually in response to an infection or a medication. TEN causes flu-like symptoms over a several day period. Inflamation of the mucous membranes then occurs. A rash covers the skin, killing the uppermost layer of skin. The dead skin will shed. This occurs over 30% of the body and can be fatal. More than a quarter of the people afflicted with this painful condition die from some type of infection.
6. Basal cell carcinomas and Squamous cell carcinoma.
Both of these skin diseases are forms of skin cancer. Basal cell carcinomas occur in the basal layer of skin. The cancer damages the tissue and causes scarring. This cancer doesn't metastasize.Squamous cell carcinoma occurs in the squamous cells,
 hence the name. Squamous cells from the skin surrounding the internal 
organs. The cancer does metastasize. The cancer can spread to the 
organs. This type of cancer kill at least 2500 people in the US each 
year.
7. Scleroderma
Scleroderma causes abnormal growth of connective tissue. The skin
 hardens and tightens. Scar tissue then forms on the skin and other 
organs in the body. This condition is believed to be an autoimmune 
disease. The more severe forms of Scleroderma can cause the lung and 
heart tissue to thicken also. When this occurs, death often results.
8. Pemphigus
Pemphigus is a group of chronic skin diseases. The skin disease is characterized by open sores
 caused by blisters. The sores can lead to infections. Severe cases of 
Pemphigus can cause lesions on the lungs and may lead to lung disease. 
This skin disease is thought to be an autoimmune disorder.
Pemphigus is treated with medications. Corticosteroids are most often 
prescribed. Treatments also include antibiotics or immunosuppressants. 
Some people require hospitalization to care for the wounds. Severe cases
 of Phempigus can result in death.
9. Leishmaniasis
Leishmaniasis is reported to have afflicted around 12 million 
people and is considered to be endemic. The disease is transmitted by 
sand flies. When the sand fly bites, they transfer the skin disease. A 
sore usually appears on the bite and scars the skin. The disease then 
causes skin lesions and ulcers.
 Tissue damage occurs in the mouth and nose. Infections attack the 
liver, bone, marrow and spleen. Other organs can also be infected.
10. Herpes Gladiatorum or Scrumpox
Scrumpox is a skin disease caused by a strain of the herpes 
virus. The skin disease causes cold sores. Sore throats, blisters on the
 face, arms, neck, and legs. As with many of the other skin disease, 
infection can be a complication of the blisters and sores. The infection
 can then lead to death. Scrumpox is spread through skin contact and is 
extremely contagious.
