Covid-Associated Mucormycosis in a Case of Wegener's Granulomatosis: A Management Challenge

A Gentleman in his 40s presented to us with left-sided hemifacial pain and nasal discharge for the last three days. He has been on immunosuppressive therapy for Wegener's Granulomatosis for over five years. Crusting was seen in the Left middle meatus upon clinical examination. Based on the post-covid status, steroid therapy, KOH mount, and radiologic imaging, a provisional diagnosis of Sinonasal mucormycosis was considered. He was posted for emergency debridement followed by Liposomal Amphotericin B and steroid therapy. Surgical histopathological specimens were suggestive of Mucormycosis. Limited sinonasal disease with no intracranial, orbital, or palatal involvement was seen in a background of Wegener's Granulomatosis, Covid, and immunosuppressive therapy. Steroids are condemned as a predisposing factor to mucormycosis. Still, the combination of Liposomal Amphotericin B and steroids was used, opening new avenues for managing mucormycosis in patients with vasculitis. The patient is well nine months post-surgery with no signs of disease relapse.
