    1. Mycetoma (Maduramycosis)
      1. Chronic progressive subcutaneous, Granulomatous infection
      2. Caused by non-acid fast Bacteria (Actinomycetoma) and fungi (Eumycetoma)
      3. Subcutaneous Nodules, abscesses, fistulae and swelling, typically on legs, and may involve hands
      4. Complications include local disfiguring lesions, and if untreated, Osteomyelitis or ankylosis
      5. Rare, life threatening systemic spread to Pelvis, lungs, spinal cord
    2. Actinomycetoma

    1. Exposure to soil or water borne organisms
    2. Granulomatous reaction up extremity lymph chain
      1. Nodular lesions
      2. Local tissue necrosis
      3. Abscess formation
    3. No systemic symptoms
  5. Labs: Histology

Mycetoma (C0024449)

Definition (MSH) A chronic progressive subcutaneous infection caused by species of fungi (eumycetoma), or actinomycetes (actinomycetoma). It is characterized by tumefaction, abscesses, and tumor-like granules representing microcolonies of pathogens, such as MADURELLA fungi and bacteria ACTINOMYCETES, with different grain colors.
Definition (NCI) A chronic granulomatous inflammation involving the deep dermis and the subcutaneous tissues. It is caused by fungi and actinomycetes.
