An Unconventional Presentation of Mucormycosis in a 10-Year-Old Child: A Case Report

Since the Coronavirus Disease (COVID-19) pandemic, there have been several unusual presentations of mucormycosis in India, especially amongst immune-competent adults. COVID-19 infection has been found to have profound effects on the patient’s immunity and some patients, though asymptomatic for COVID-19, can be infected by mucormycosis and develops dangerous complications. Skin involvement of the orbital, zygomatic and maxillary areas is a common occurrence in extensive cases of rhino-orbital mucormycosis, however, isolated involvement of the alar skin is an extremely rare occurrence in such patients. Paediatric cutaneous mucormycosis is by itself a rare entity, seen majorly in children with history of allogeneic hematopoietic stem cell transplantations, chemotherapeutic treatment, or patients with human immunodeficiency virus infections, herpes and other life-threatening viral infections. Patients receiving long-term steroid therapy are also predisposed to invasive fungal infections. This case was about a 10-year-old boy presented with a black crusted lesion over the nose to the otolaryngology outpatient department. The patient had history of contact with a COVID-19 positive individual. Examination revealed a necrotic patch over the palate and Non Contrast CT Scan of (NCCT) the paranasal sinuses showed pansinusitis. A KOH mount showed fungal elements and the patient underwent emergency debridement of nasal skin with endoscopic sinus and palatal debridement. Injectable liposomal Amphotericin-B was started. Over a period of one month, the patient showed significant clinical improvement. Though rare, sinonasal mucormycosis can present in the form of a cutaneous lesion which is an unconventional symptom. A general awareness amongst healthcare professionals, with a multidisciplinary approach, timely diagnosis and specialist intervention can improve outcomes in this sinister disease.
