Overview


Linear porokeratosis is a skin condition that most often begins in infancy or early childhood, but it can occur at any age.  The main feature of this condition is the development of reddish brown, slightly raised markings on the skin arranged in lines or streaks on one side of the body.  These markings are not usually painful, though they can sometimes cause open sores in the skin.  There is up to an 11% chance that these markings could progress to skin cancer (basal cell cancer or squamous cell carcinoma) over time.  The exact cause of linear porokeratosis is unknown, but risk factors may include exposure to the sun or radiation, problems with the immune system (immunosuppression), or genetic predisposition.[1]
