Lichen simplex chronicus is a skin disease that mostly affects female patients,
with a peak incidence between ages 35 and 50 years. On the scalp, it appears as
a single or multiple oval lesions, showing scaling and hair shaft loss or
breakage. An important dermoscopic feature of the disease are the "broom
fibers." Histopathology reveals the "hamburger" and the "gear wheel" signs. The
aim of this report is to demonstrate a case of lichen simplex chronicus on the
scalp with typical and exuberant clinical, dermoscopic, and histopathological
findings.
