Dermatosis (plural dermatoses), a noun, is defined as "any disease of the skin,"^[1]^[2]^[3] and, while thousands of skin disorders have been described, only a small number account for most visits to the doctor.^[3] Uncommon presentations of common diseases are common.^[4]

[edit] History

Avicenna's The Canon of Medicine (1025) described treatments for a variety of skin conditions, including skin cancer. The preferred medication it recommended was zinc oxide. Though today it is no longer used for treating skin cancer, it is still widely used today to treat a variety of other skin conditions, in products such as baby powder and creams to treat diaper rashes, calamine cream, anti-dandruff shampoos, and antiseptic ointments.^[5]

In 1572, Geronimo Mercuriali of Forlì, Italy, completed De morbis cutaneis (translated "On the diseases of the skin"). It is considered the first scientific work dedicated to dermatology.

In World War I, over two million days of service are estimated to have been lost by reason of skin diseases alone.^[6]

[edit] Clinical findings

The most important clinical questions are location of the skin lesions (arms, head, legs, etc.), symptoms (pruritus, pain, etc.), duration (acute or chronic), arrangement (solitary, generalized, annular, linear, etc.), morphology (macules, papules, vesicles, etc.), and color (red, blue, brown, black, white, yellow, etc).^[4]
