Clinicopathological spectrum of pityriasis lichenoides: A case series of 19 patients

Figure 1 Clinicodermoscopic spectrum of pityriasis lichenoides. A: Acute-spectrum presentation with multiple erythematous-brown papules, several showing central crusts at different evolutionary stages on the extremity; B: Dermoscopy of an acute-spectrum lesion showing a central reddish-brown amorphous/crusted area with a peripheral white collarette of scale and dotted/glomerular vessels; C: Chronic papular presentation pityriasis lichenoides chronica C-like (PLC-like) with fine scaling on the back; D: Dermoscopy of a PLC-like lesion showing a central brown-crusted plug over a yellow-brown structureless background with peripheral fine scale and sparse vessels. These findings align with recent dermoscopic descriptions and may aid recognition without biopsy.
