Historical References To Psoriasis

Psoriasis has been around since the days of Greek mythology, more than 2,500 years ago. It was considered a curse from the gods.The Bible refers to psoriasis but mistakenly calls it leprosy. For hundreds of years, people with the disease were ostracized and forced to wander as homeless beggars. Some had to wear warning bells so others could avoid their paths. Some suffered the same fate as lepers, who were burned at the stake in the 14th century."Amazingly, psoriasis was a disease that had been misunderstood for more than 2,000 years before it was clearly defined (in the early 1800s) and named what we know it as today."

Types Of Psoriasis

There are five different types of psoriasis. The most common form of psoriasis is called "plaque psoriasis," which is characterized by well-defined patches of red, raised skin. About 80 percent of people with psoriasis have this type.
Plaque psoriasis can appear on any skin surface, although the knees, elbows, scalp, trunk and nails are the most common locations.
The other types of psoriasis are:
Guttate described as small, red, individual drops on the skin.
Inverse psoriasis is smooth, dry areas of skin, often in folds or creases, that are red and inflamed but do not have scaling
Erythrodermic psoriasis is characterized as periodic, widespread, fiery redness of the skin. Pustular psoriasis which involves either generalized, widespread areas of reddened skin, or localized areas, particularly the hands and feet (palmo-plantar pustular psoriasis).

Typically, people have only one form of psoriasis at a time. Sometimes two different types can occur together, one type may change to another type, or one type may become more severe. For example, a trigger may convert plaque psoriasis to pustular.
