Using free flaps for reconstruction during infections by mucormycosis: A case report and a structured review of the literature

Background. - Mucormycosis is a very rare infection caused by fungi from the order Mucorales, it rarely involves the skin. We report a case of necrotizing fasciitis of the upper limb which required an aggressive surgical debridement, antifungal therapy and coverage of the defect with a free DIEP flap, a review of the literature was also done regarding indications of reconstruction with free flaps. Case presentation. - Here we present a case of cutaneous mucormycosis of the right upper limb in a 49-year-old immunocompetent woman after having an open fracture associated with massive contamination during a motor vehicle collision. In early postoperative period, she had multiple skin necrotic lesions. Serial surgical debridements were performed and ended up with interscapular-thoracic amputation associated with a total mastectomy. Following diagnosis confirmation of mucormycosis infection, the patient was started on antifungal therapy for several months. After disease control, the large defect was successfully covered by a DIEP flap. Conclusion. - Cutaneous mucormycosis requires antifungal therapy along with aggressive debridement, reconstruction by a free flap seems to be a good solution to cover these large defects.
