Mycetoma are a broad group of fungal infections that characteristically originate in the skin and subcutaneous tissues of the foot.
[18] If not treated appropriately and in a timely fashion mycetoma infections can extend to deeper tissues like bones and joints causing osteomyelitis.
[19] Extensive osteomyelitis can necessitate surgical bone resections and even lower limb amputation.
[20] Some examples of common fungal skin infections include: Parasitic infestations of the skin are caused by several phyla of organisms, including Annelida, Arthropoda, Bryozoa, Chordata, Cnidaria, Cyanobacteria, Echinodermata, Nemathelminthes, Platyhelminthes, and Protozoa.
[28] Virus-related cutaneous conditions caused by these obligate intracellular agents derive from both DNA and RNA viruses.
