Lichen Striatus - Causes, Symptoms And Treatment

What is Lichen Striatus ?

Lichen Striatus is an uncommon type of eczema that is seen in young children. Lichen striatus begins similarly to lichen planus, with small bumps (papules), but over a period of days expands to form a long streak or band of affected skin. It is linear in nature which is quite typical and is itchy. Lichen striatus is a rash that consists of small raised bumps. It usually involves the arms and legs, but can affect any part of the body. Females are affected two to three times more than males. Lichen striatus condition is seen frequently in children less than 16 years old but, also occurs in adults.

Causes of Lichen Striatus

The cause of lichen striatus is unknown. However the lichen striatus is not dangerous or contagious. It occurs mainly in children aged between 5 and 15 years. Lichen Striatus is not related to cancer and it does not involve internal organs.

Symptoms of Lichen Striatus

Lichen striatus starts as small pink, red or flesh coloured spots that over the course of one or two weeks join together to form a dull red slightly scaly linear band. The band is usually 2mm to 2cm in width and may be a few centimetres in length or may extend the entire length of the limb. Usually there are no symptoms but some patients may complain of slight or intense itching.

Sometimes there are two parallel bands. Lesions occur most commonly on one arm or leg but can affect the neck or trunk. Sometimes a band may extend from the leg onto the buttock or abdomen.

Treatment of Lichen Striatus

There is no specific treatment for lichen striatus. In most patients lichen striatus goes away by itself after six months to one year. Emollients or topical steroids may be used to help treat dryness or itching. Cortisone creams and ointments are also helpful in the treatment of Lichen Striatus .
