The present case highlights bacterial fasciitis associated with fungal (Mucor) infection with insidious angioinvasive nature (Saksenaea vasiformis) which required amputation, negative-pressure vacuum dressings and amphotericin B for definitive treatment. This demonstrates a relatively rare case of the group IV classification of necrotising fasciitis, which we must consider when there is slowly progressing tissue death despite seemingly adequate treatment.
