The pandemic of coronavirus disease 2019 (COVID-19) still remains on an upsurge trend. The second and the waves of this disease have led to panic in many countries, and some parts of the world suffering from the fourth wave. In the midst of this pandemic, COVID-19 patients are acquiring secondary infections such as mucormycosis also known as "black fungus disease". Mucormycosis is a serious, but rare opportunistic fungal infection that spreads rapidly, and hence prompt diagnosis and treatment are necessary to avoid mortality and morbidity rate. We report in this paper, a case of a diabetic patient who presented with bilateral nasal obstruction, anosmia, and frontal headache diagnosed with rhino cerebral mucormycosis developing after COVID-19 infection with a favorable outcome after a medico-surgical treatment. Through this case, we aim to aware patricians of this possible association and the importance of early diagnosis to optimize treatment outcomes.
