Porokeratosis Is a rare skin disorder characterized by lesions with a thin center and ridge like border.

What causes porokeratosis?

As skin cells mature, they harden by accumulating a protein called, keratin. Porokeratosis is a disruption of this process resulting in the development of crater-like skin lesions. Porokeratosis can occur as a result of trauma to the skin such as burns, wounds or infections. Risk factors contributing to Porokeratosis are genetics, exposure to UV light or a weakened immune system.

What are the symptoms?

Porokeratosis produces a few lesions or sometimes patches of spots which have a defined center surrounded by a raised ring. Sun exposed areas are most commonly affected, especially arms and legs, but they can appear anywhere on the body. Porokeratosis affects women twice as often as men and generally shows up in adults between 30 and 40 years old.

How is Porokeratosis diagnosed?

Porokeratosis is usually diagnosed by a dermatologist. A biopsy may sometimes be obtained for examination under a microscope, however most porokeratosis lesions are benign and do not become skin cancer.
