The diversity and outcome of post-covid mucormycosis: A case report

INTRODUCTION AND IMPORTANCE: The impact of Covid-19 pandemic on the incidence and pattern of Mucormycosis (the black fungus), has increased sharply and is featured as an epidemic within a pandemic. The majority of cases were detected at late stages, which decreases the chances of survival. CASE PRESENTATION: The authors present a case of an immunocompetent male patient diagnosed with left orbital apex syndrome post covid-19 infection, which necessitated orbital exenteration. He was later hospitalized in a quarantine facility and an area of skin breakdown on his left cheek was noted and surgical debridement performed. Later, He presented to our institution with left hemifacial skin loss, exposing the underlying diseased bone. A multidisciplinary team examined the patient clinically and radiographically, reaching a primitive diagnosis of secondary cutaneous Mucormycosis due to rhino-orbital Mucormycosis, with no cavernous sinus thrombosis nor cranial extension. Radical surgical and medical treatments were given and he had an uneventful recovery. Unfortunately, he died 5 days after the reconstructive surgery with Anterolateral Thigh (ALT) flap. CLINICAL DISCUSSION: The dual effect of both covid-19 and its' associated Mucormycosis, predispose patients to increased risk of pressure injuries including Medical device related pressure injuries. Survivors of Mucormycosis are high-risk patients, and planning their reconstruction by free flaps is challenging. However, delayed reconstruction is recommended. CONCLUSION: Early diagnosis and management of covid-19 associated Mucormycosis should be prioritized. Moreover, surgical debridement of necrotic tissues should not be delayed due to an unavailable or negative histopathology.
