    Background:

    • Nail discoloration can present diagnostic challenges.
    • Accurate diagnosis is crucial for appropriate treatment and patient management.

    Observation:

    • A patient presented with a greenish-black discoloration of the great toenail.
    • Microscopic examination and culture identified Pseudomonas aeruginosa as the causative agent.

    Findings:

    • The greenish-black discoloration was confirmed to be Pseudomonas chromonychia.
    • This condition can mimic other subungual pathologies.

    Implications:

    • Clinicians should consider Pseudomonas chromonychia in the differential diagnosis of nail discoloration.
    • Distinguishing this infection from subungual hematomas, nevi, or melanomas is essential for correct treatment.
