Nail Fungus (Onychomycosis): Symptoms, Complaints, Signs

The following symptoms and complaints may indicate onychomycosis (nail fungus):

  • Yellowish discoloration of the nail
  • Onycholysis – detachment of the nail plate.
  • Grooving in the area of the nail plate
  • Subungual hyperkeratosis – cornification disorder occurring under a fingernail or toenail.
  • Thickened nails
  • Deformed nails
  • Decay of the nail

Note: An exclusive clinical diagnosis of onychomycosis is not sufficient! For diagnosis, a mycological laboratory examination (microscopic fungal detection; native preparation) and cultural detection of the fungi in the untreated patient is required.
