When the host’s defenses are compromised, such infections are associated with severe morbidity and mortality. Here, a rare case of fungal infection in a 61-year-old immunocompetent male patient from Saudi Arabia was reported, who suffered from pulmonary hemorrhage and Systemic Lupus Erythematous. Bronchoalveolar Lavage was used as a diagnostic tool to identify the fungus reported in the case. The pathogenic fungal specie identified as Magnusiomyces capitatus, in macroscopic and microscopic morphological characteristics of the colonies. Based on clinical evidence, liposomal amphotericin formulation was recommended for initial therapy against fungal infection. Also, liposomal amphotericin B induced mycological eradication up to 70 percent in patients with proven Magnusiomyces capitatus infection. In addition to addressing suspected Systemic lupus erythematosus, the patient’s health has improved with no evidence of pulmonary bleeding and hemoptysis.展开更多
