  • Pityriasis lichenoides chronica (PLC) is a lymphoproliferative papulosquamous condition with varying presentations.

  • In lighter skin, it tends to present with pink to red papules and macules with background erythema and variable scale.

  • In darker skin, presentation also includes scaly papules and macules but varies in color from violaceous and dark brown to hypopigmented. This often resolves with postinflammatory pigment alteration.
