RT Journal Article SR Electronic T1 Saksenaea mucormycosis: a rare and dangerous cause of necrotising fasciitis JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e254183 DO 10.1136/bcr-2022-254183 VO 16 IS 3 A1 Sykes, Blake Anthony A1 Krause, Hans A1 Lamparelli, Michael A1 Austin, David YR 2023 UL http://casereports.bmj.com/content/16/3/e254183.abstract AB Necrotising fasciitis is a rapidly progressing soft tissue infection requiring early and adequate surgical debridement and appropriate antibiotic cover. 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.
