ClassificationThis section has been translated automatically.
- External causes (simple onycholysis)
- Toxic degenerative due to constant water contact (see below Onycholysis, partial).
- Traumatic (constant leverage effects), this concerns especially the onycholysis of the toenails - here tight footwear. Also due to incorrect nail modeling (artificial nails too long, constant leverage effects on the natural nail).
- UV -rays photoonycholysis - (without influence of sensitizing drugs)
- Primary skin diseases (with nail involvement)
- Psoriatic diseases of hands or feet (psoriatic onycholysis)
- Psoriatic arthritis (also without psoriatic skin symptoms)
- erythema multiforme
- Alopecia areata (especially to be observed in alopecia areata totalis)
- Dysplasia, ectodermal
- Atopic dermatitis especially with acral affection
- Pachyonychia congenita
- Parakeratosis Hjorth-Sabouraud
- POPP syndrome
Hereditary distal onycholysis with scleronychia
- Metabolic/systemic diseases
- Hyperthyroidism/hypothyroidism possibly in combination with autoimmune thyroiditis (see thyroid disorders skin changes below); onycholysis may be an early indicator (Malan M et al. 2019)
- Yellow-nail syndrome
- chronic graft-versus-host disease
- M. Crohn's disease (painful onycholysis described)
- chronic terminal renal failure especially in long-term dialysis (see below renal diseases, skin changes), protoporphyria erythropoetica (photoonycholysis)
- Benign and malignant subungual growths with secondary onycholysis
- subungual exostoses
- subungual malignant melanoma
- subungual squamous cell carcinoma
