Clinical Classification

Clinical Information

  • Trichosporonosis

    fungal infections caused by trichosporon that may become systemic especially in an immunocompromised host. clinical manifestations range from superficial cutaneous infections to systemic lesions in multiple organs.
  • Cerebral Phaeohyphomycosis

    cns infections caused by neurotropic dematiaceous fungi that contain melanin in their cell walls. the infections often result in brain abscess; encephalitis; and meningitis in patients who are often immunocompetent. the common causative fungi include members cladophialophora bantiana, exophiala dermatitidis, rhinocladiella mackenziei, and ochroconis gallopavum. r. mackenziei infection is seen almost exclusively in patients from the middle east.
  • Phaeohyphomycosis

    opportunistic infections caused by the dematiaceous (darkly pigmented) mitosporic fungi of alternaria, bipolaris, cladosporium, curvularia, and exophiala. these fungi have pigmented hyphae due to melanin in the cell wall. the initial subcutaneous cyst from the infection can become systemic and spread rapidly to renal, pulmonary and cerebral systems (see cerebral phaeohyphomycosis) in an immunocompromised host.
  • Fungal Keratitis

    keratitis caused by fungi.

Patient Education

Fungal Infections

If you have ever had athlete's foot or a yeast infection, you can blame a fungus. A fungus is a primitive organism. Mushrooms, mold and mildew are examples. Fungi live in air, in soil, on plants and in water. Some live in the human body. Only about half of all types of fungi are harmful.

Some fungi reproduce through tiny spores in the air. You can inhale the spores or they can land on you. As a result, fungal infections often start in the lungs or on the skin. You are more likely to get a fungal infection if you have a weakened immune system or take antibiotics.

Fungi can be difficult to kill. For skin and nail infections, you can apply medicine directly to the infected area. Oral antifungal medicines are also available for serious infections.

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
