Fungal Infections and Studies

The etiological agents of infrequent invasive fungal infections (IFI) are difficult to identify on the species level using classic morphological examination. We describe the first case of an IFI caused by Cephalotrichum gorgonifer in a neutropenic patient with a hematological malignancy and put it on the map as a new causative agent of IFI. Case report, microbiological findings and description of the etiological agent. A 60-year-old man was diagnosed with mantle cell lymphoma. A CT scan confirmed the presence of lung infiltrates located at the right upper lobe. Histological examination of one of the nodules showed a large number of narrow septate hyphae with acute-angle branching and irregular round cell morphology; vessels walls appeared infiltrated, proving an angioinvasive pulmonary IFI. Sample culture resulted positive and molecular identification proved the presence of Cephalotrichum gorgonifer. Voriconazole was used for 12 months and the patient did not report any complications or side effects. Complete remission of lymphoma was achieved later by the time chemotherapy, radiotherapy, and radioimmunotherapy consolidation were completed. We recommend the inclusion of Cephalotrichum gorgonifer in the list of opportunistic pathogens causing mycoses in neutropenic hematological patients with suspected mould-related IFI.
