Albinism is a genetic condition resulting in a lack of pigmentation in the eyes, skin and hair. It is an inherited condition arising from the combination of recessive genes passed from both parents of an individual. A variety of problems with photosensitivity in eyesight and skin usually result from the condition.

Cellulitis is an infection of the deeper layers of the skin and the underlying tissues with the affected area suddenly turning red, painful, swollen and hot.
Cowden disease (CD), also termed Cowden syndrome and multiple hamartoma syndrome, is an autosomal dominant condition with variable expression that results from a mutation in the PTEN gene on chromosome arm 10q, as reported by Liaw et al. CD causes hamartomatous neoplasms of the skin and mucosa, GI tract, bones, central nervous system (CNS), eyes, and genitourinary tract. Skin is involved in 90-100% of cases; the thyroid in 66%.
Dercum's disease, Dercum disease, Adiposis Dolorosa, Morbus Dercum, Adiposita Dolorosa, Fettvävsreumatism, painful fatty tumors, lipomas, weakness, obesity. This category is about a disease that has been identified for over a hundred years, yet no recent research exists on the cause of it. It was originally named by Dr. Francis X. Dercum in 1892 as adiposis dolorosa. It has since picked up his name as an identifier and both names seem to be equally popular. It generally occurs in women (less 16% are men), between the ages of 25-40 (in Sweden) or 40-65 (in the USA). They cite obesity as a cause, but they have it backwards -- the disease actually causes the obesity -- and weight reduction efforts have little effect on the pain or the obesity. Two articles has attributed it to an autosomal dominant genetic disease, but there is no explanation why it can be benign in some and so debilitating in others. There is no cure, and no easy way to diagnose that a person has this disease. The key(s) are painful fatty deposits (benign lipomas, either encapsulated or diffuse), where the pain has been evident for three (3) months or more. All treatments are palliative -- treat the symptoms -- ease the pain, suction out (via liposuction) or excise the more painful tumors (remember they are benign), and counsel the patient to be able to endure the never-ending pain. Research into the cause or the stimulus that worsens the disease is needed.
Please submit unique web sites that deal with the Dercum''s Disease (Adiposis Dolorosa), or web sites that might shed light on the mechanism that might cause such a disease.

Ectodermal Dysplasia (ED) is not a single disorder, but a group of closely related conditions. More than 150 different syndromes have been identified.

Eczema is a catchall term for a variety of itchy skin inflammations/rashes which may be characterized by redness, oozing, crusting, blistering, scaling, and/or hardening.

The most common is Atopic Dermatitis with some others being Contact Dermatitis, Hand Eczema, Nummular Dermatitis, Perioral Dermatitis, Pompholyx, Seborrheic Dermatitis.

Head lice are specialized to live among the hair present on the human head and are exquisitely adapted to living mainly on the scalp and neck hairs of their human host.

The term "rash," though often used by patients and clinicians alike, is a very general term that explains a number of different skin conditions. Rashes can be caused by a variety of factors including exposure to environmental agents, allergies, viruses, reaction to drugs and medications, and pests like lice or the scabies mite. While most rashes are not serious and last only a few hours to a day or two, some skin outbreaks can be indicators of life threatening conditions and it is important to understand the characteristics of these rashes.

Solar keratosis, also known as actinic keratosis or "sun spots", is a common skin condition caused by exposure to the sun. Typically small in size (usually smaller than a pencil eraser), a solar keratosis lesion is often red with a scaly or crusty layer. It usually develops many years after the exposure, and if untreated, a small percentage can go on to become skin cancer.
If detected early enough, it is usually easily treated without the need for surgery.

Vitiligo (or leukoderma) is the patchy loss of skin pigmentation due to an auto-immune attack by the body's own immune system on skin melanocytes. It frequently begins in late adulthood, with patches of unpigmented skin appearing on extremities. The patches may grow or remain constant in size. Occasional small areas may repigment as they are recolonised by melanocytes.
