ICD-11 definition : Actinomycetoma is a chronic progressive subcutaneous infection caused by implantation
of aerobic branching actinomycetes through a skin wound. These organisms are filamentous
bacteria which live as saprophytes in soil or on plants; the commonest infecting agents
are Nocardia brasiliensis, Actinomadura madurae and Streptomyces somaliensis. The
earliest stage of infection is a firm painless nodule but with time the whole area
becomes hard and swollen with multiple papules, pustules and draining sinuses on the
skin surface. Extension to underlying bones and joints can result in gross deformity.;
ICD-11 synonym : Actinomycotic Madura foot; Mycetoma due to filamentous bacteria; Actinomycotic mycetoma;
