Cutaneous Mucormycosis of the Upper Extremity

Abstract Mucormycosis is a devastating fungal infection known for its angioinvasive spread and hematogenous dissemination, quickly resulting in multiorgan involvement and potentially fatal complications. Timely diagnosis is essential to facilitate early, aggressive debridement, yet the diagnosis remains difficult to obtain because of the need for culture and microscopy diagnosis. We provide case examples, which highlight diagnostic pearls and the multidisciplinary approach that are critical for improving local outcomes, preventing systemic spread, and reducing mortality.
