His wife reports that he has a history of type 1 diabetes mellitus. His temperature is 38.8C 101.8F. He is confused and oriented only to person. Examination shows left periorbital swelling that is tender to palpation, mucopurulent rhinorrhea, and a black necrotic spot over the nose. There is discharge of the left eye with associated proptosis. A photomicrograph of a specimen obtained on biopsy of the left maxillary sinus is shown. Which of the following is the most likely causal organism?? A: Pseudomonas aeruginosa, B: Rhizopus microsporus, C: Aspergillus fumigatus, D: Blastomyces dermatitidis, E: Pneumocystis jirovecii,  <response>: This is a patient with symptoms of confusion, fever, and facial swelling and discharge suggestive of sinusitis. The description of black necrotic tissue over the nose and eye proptosis indicates possible fungal infection. The photomicrograph shows broad, aseptate hyphae most consistent with mucormycosis caused by Rhizopus species. Mucormycosis is an aggressive fungal infection that can occur in immunocompromised patients like those with diabetes. Pseudomonas and Aspergillus can cause sinusitis but are less likely to present this way. Blastomyces and Pneumocystis do not match the morphology.B: Rhizopus microsporus
