7 Rare Skin Diseases

5. Dermatographia

This rare condition is characterized by extremely sensitive skin. It is usually contracted by the skin that responds or reacts adversely to the slightest of stimulants like a light scratch or minor injury. The hypersensitivity is the response of the individual’s immune system that releases histamine in huge quantities. Histamine results in dilating capillaries causing skin to become red and raised.

6. Harlequin Ichthyosis

This genetic skin problem is rare where skin becomes very thick and sheds off at least ten times faster than it does in normal individuals. Thick scales that crack renders skin a fish like look. Hair also grows on these scales.

7. Argyria

This terrible skin condition is equally rare where skin turns grayish blue or blue in color. One of the cases reported in the United States is about an individual who ingested colloidal silver to cure his arthritis after seeing an advertisement in a magazine. The condition is caused due to exposure to silver dust or compounds in an improper manner. Accumulation of silver makes skin look dark with increased exposure to sunlight.
