Onychodystrophies (changes in the nail plate)

  • Longitudinal grooves (special form: Dystrophia mediana canaliformis); frequent growth disturbance of the nails also due to age. Can lead to triangular tears and splintering at the free edge of the nail.
  • Transverse grooves(Beau-Reilsche transverse furrows of the nails)
  • Onychauxis (nail thickening while maintaining transparency)
  • Leukonychia punctata
  • linear leukonychia
  • Lunulae triangulares (triangular lunulae, e.g. in nail-patella syndrome)
  • Onychisis (lamellar splitting of the nail in longitudinal and transverse direction, see below) onychorrhexis)
  • Onycholysis (detachment of the nail plate - for causes see there)
  • Atrophy of the nail plate up to anonychia (often with pterygium formation)
  • Soft, brittle nails (iron deficiency anaemia, vitamin A overdoses)
  • Onychorrhexis (hard, thickened and splintering nails)
  • Pachyonychia congenita
  • Tubular nail (unguius in turricolo)
  • Watch glass nails(see also macroonychia)

Nail signs due to diseases of the nail bed

Diseases of the peri- paro and epinychium

  • bulla repens
  • Fibrokeratome digital acquired
  • Paronychia in dyskeratosis congenita (rare)
  • paronychia, bacterial
  • paronychia candidamycetica
  • paronychia, syphilitic (blistery or pustular skin changes with infestation of the paronychium and nail detachment in syphilis connata)
  • Hyperkeratotic nail fold (in dermatomyositis and progressive systemic scleroderma)
  • Megacapillaries in dermatomyositis and progressive systemic scleroderma

  • Splinters and other foreign bodies
  • Chronic injuries of the nail matrix by sports shoes (due to frequent bumping of the toes)
  • Traumatic nail bruises due to dorsal or frontal pressure events.
  • Nail misalignment in childhood
