Q
Give the subcutaneous mycoses with the given data:
- Clinical picture similar to actinomycotic mycetomas. Disease is slowly progressive, with patients frequently dying of secondary infections.
- Treatment consists of excising early, localized lesions (amputation may be required for advanced infections). Anti-fungal drugs have little effect.
- Body tries to wall off the offending fungus. Invasion of deeper tissue may follow, with bone involvement, draining sinus tracts, or progression through the lymphatics.
A
