B35-B49: Mycoses

B47: Mycetoma

Mycetoma is a chronic, progressive disease that primarily affects the skin and underlying tissues, but which can also spread to bone in severe cases. It is caused by certain types of fungus or bacteria that are usually introduced into the body via a minor cut or puncture wound. Once in the body, these organisms can cause a localized infection that gradually expands, causing swelling, inflammation, and the development of grain-like structures in the tissue that can discharge pus. Common symptoms can include swelling, pain, and discharge from the affected area, as well as possible formation of channels from the infection site to the skin surface. Disease progression is typically slow but can lead to serious complications, including disability and deformity, if not treated in a timely manner. Mycetoma is typically found in tropical and subtropical regions, where individuals may be more exposed to the causative organisms through barefoot farming or other similar activities.
