Mycetoma is a type of a slowly progressive chronic subcutaneous infection caused by actinomycetes or true fungi. A local trauma like cut or splinter can cause the infection leading to a granulomatous reaction. Infection tracks through skin, facial planes and can sometimes involve the underlying bone. Most commonly the foot is involved but also hands, back or shoulders can be involved.A 43 year old male, with ankle and foot swelling, with no discharging sinuses was studied at our institute. Initially, provisional diagnosis of tuberculous osteomyelitis was made, which latter turned out be mycetoma.
