Skin lesion of blastomycosis

  • Symptoms

    Skin symptoms occur in about 80% of people whose blastomycosis infection spreads beyond their lung.

    Papules, pustules, or nodules are most frequently found on exposed body areas.

    • They may look like warts or ulcers.
    • They are usually painless.
    • They may vary from gray to violet in color.

    The pustules may:

    • Form ulcers
    • Bleed easily
    • Occur in the nose or mouth

    Over time, these skin lesions can lead to scarring and loss of skin color (pigment).


    Signs and tests

    The infection is diagnosed by identifying the fungus in a culture taken from a skin lesion. This usually requires a skin biopsy.
