Skin lesion of histoplasmosis

  • Symptoms

    The symptoms may include:

    • Mouth ulcer, usually painless
    • Pustules or nodules all over the body
    • Red spots on the skin (erythema nodosum)
    • Red lumps on the skin (erythema multiforme), usually on the lower legs

    Signs and tests

    In some cases, a biopsy of the skin lesion can identify the fungus. Rashes due to erythema nodosum and erythema multiforme, however, usually do not have fungus in them. Blood and urine tests may help detect the fungus in some cases.
