Nosocomial mucormycosis of the thigh.

We describe a case of nosocomial mucormycosis of the thigh in an immunocompromised patient admitted with COVID-19 acute respiratory distress syndrome.

A necrotic skin lesion developed in a 54-year-old man admitted to the intensive care unit with acute respiratory distress syndrome (ARDS) caused by COVID-19. The lesion occurred at the site of a thigh hematoma caused by arterial line insertion one month earlier. The patient was known for diffuse large B-cell lymphoma and had received chimeric antigen receptor T cells 7 months prior to presentation. He was receiving dexamethasone and was on veno-venous extracorporeal membrane oxygenation (ECMO) for COVID-19 ARDS. Physical examination demonstrated a 23.5-centimeter x 13-centimeter necrotic eschar superimposed by white mycelium (Fig. 1). Culture of the mycelium grew Rhizopus species, within the Mucorales fungal order. The patient was started on amphotericin B deoxycholate and posaconazole and taken urgently to the operating room for debridement. Intraoperative assessment demonstrated deep fungal tissue invasion (Fig. 2). The patient died 24 h after surgery.
