Nail Discoloration

Nail discoloration refers to abnormal changes in nail color—yellow, brown, green, or black. Causes include fungal infections, trauma, medications, underlying disease, or pigment changes. Cutis Hospitalʼs dermatology team offers diagnostic evaluation and targeted management to restore nails to a healthy appearance.

Overview

Discoloration may present as yellowing (fungal infection), brown or black streaks (melanonychia), white spots (leukonychia), or green Pseudomonas infection). Toenails or fingernails may be affected. Diagnosis often involves clinical exam, fungal scraping, and sometimes biopsy to exclude melanoma.

Nail color changes may signal infection, injury, or system illness. At Cutis Hospital, we conduct thorough assessment including culture and sometimes labs to pinpoint causes—offering effective therapy, prevention, and reassurance.

What causes nail discoloration?

Fungal infection (onychomycosis), bacterial infection, trauma, smoking, medications, systemic illness (liver, kidney, diabetes), or pigmentation disorders.

How is discoloration managed?

Treat underlying cause—antifungal or antibiotic therapy, biopsy of pigment streaks, topical whitening agents, or systemic review for disease association.

Are there risks?

Some pigment changes (brown/black) may indicate melanoma—requires urgent evaluation and biopsy.

How is discoloration managed?

Resolution varies—fungal and bacterial cases improve in weeks; pigment disorders or trauma heal with nail growth over months.

How long does recovery take?

Resolution varies—fungal and bacterial cases improve in weeks; pigment disorders or trauma heal with nail growth over months.
