Lichen striatus is a rare, benign skin condition that typically affects children. It is characterized by the sudden onset of linearly arranged, small, flat-topped, flesh-colored or pinkish papules. The condition is self-limiting and usually resolves without treatment within a year.
Etiology[edit]
The exact cause of lichen striatus is unknown. However, it is believed to be an inflammatory response to an unknown trigger. Some researchers suggest that it may be related to a viral infection or an autoimmune response. Viral infections and autoimmune responses are both known to cause inflammation in the body.
Clinical Presentation[edit]
Lichen striatus typically presents as a linear band of small, flat-topped, flesh-colored or pinkish papules. The band usually starts at one end of the body and progresses to the other end over a period of weeks. The most common sites of involvement are the limbs, especially the legs. The rash is usually asymptomatic, but some patients may experience mild itching.
Diagnosis[edit]
The diagnosis of lichen striatus is primarily based on the characteristic clinical presentation. A skin biopsy may be performed to confirm the diagnosis. The histopathological findings typically show a lichenoid tissue reaction with a band-like infiltrate of lymphocytes in the upper dermis.
Treatment[edit]
Lichen striatus is a self-limiting condition that usually resolves without treatment within a year. However, topical corticosteroids may be used to alleviate any associated itching. In some cases, the condition may recur.
Prognosis[edit]
The prognosis for lichen striatus is excellent. The condition is benign and does not cause any long-term health problems. However, it may cause temporary discoloration of the skin, which usually fades over time.
