ABSTRACT
Mucormycosis is a rare fungal infection mostly encountered in immunosuppressed patients. Other major risk factors are diabetes mellitus, solid organ transplant and chronic use of glucocorticoids. Early diagnosis should be obtained as soon as possible due to the infection's aggressive behavior and high probability of dissemination. Here we present a case of pulmonary mucormycosis in a non-diabetic patient, known to have systemic lupus erythematous and had a renal transplant recently presented with shortness of breath and was treated with antibiotic as a case of chest infection with minimal improvement. Then, after full investigations, he seemed to have mucormycosis which was successfully treated with combined liposomal amphotericin B and resection of the infectious lesion.
