We present a case of a man who was simultaneously diagnosed with a small cell non-Hodgkin lymphoma and a sphenoid sinusitis by S. commune. Intraoperative observation and histology description were crucial to consider an alternative diagnosis to mucormycosis suggested by the MRI. The diagnosis was made based on PCR identification and sequencing.engSchizophyllum communeSinusitisNon-Hodgkin LymphomaMolecular DetectionFungal SinusitisImmunosuppressionInfecções Sistémicas e Zoonosesjournal article10.1016/j.mmcr.2020.04.003
