Background: Lichen striatus (LS) is a benign, mostly self-limiting dermatological condition, primarily affecting the skin, and sometimes the nails. It is characterised by the sudden onset of a band-like rash, typically following Blaschko lines. The exact cause of LS is not well established, but it is believed to be an abnormal immune response to the altered keratinocyte clone after a triggering event.

Article Synopsis
  • Lichen striatus (LS) is a self-resolving skin condition primarily affecting children, characterized by a linear pattern and mainly seen in females, with an average patient age of 3.8 years.
  • A review of 27 articles involving 440 patients suggests that LS may be linked to immune system dysregulation, where cytotoxic T-cells attack skin cells after losing immune tolerance.
  • It is mostly diagnosed clinically based on its unique characteristics, with a typical duration of about 9.5 months, and treatment is rarely needed, highlighting the benign nature of the condition while also pointing out the need for more research in this area.

  • A case of a 78-year-old woman revealed erythema nodosum as her initial manifestation following a tick bite; she was effectively treated with antibiotics and anti-inflammatory medications, and prescribed adjustments for her outpatient care.
