Cockade / cockarde ribbon

  • Also called cockade nevus, kokardennaevus or naevus en cocarde / cockarde
  • Usually children
  • Postulated that cockade nevi and eclipse nevi may represent UV-induced immune attack on developing melanocytes (Clin Exp Dermatol 2006;31:596)
  • Trunk is most common location
Clinical features
  • Concentric (targetoid) pattern of pigmentation with central papule (pink to brown / black) surrounded by clear zone, then outer stippled pigment
  • Zonation may be due to failure of melanin synthesis (Acta Derm Venereol 1980;60:360)
Case reports
  • Biopsy of childhood scalp lesions not necessary, but presence may indicate higher overall lifetime risk of melanoma (Arch Dermatol 2009;145:1334)
  • Darker central globular pattern, lighter homogenous inner ring and peripheral darker reticular ring (Br J Dermatol 2011;165:137)
