Rare cutaneous fungal infection due to Nigrograna chromolaenae in a heart transplant recipient
Abstract
Introduction: Solid organ transplant recipients are particularly prone to infections, and many germs can be involved, including opportunistic pathogens. Regarding catheter-related infections however, the number of causative microorganisms is most often limited to germs of the skin flora, rare enterobacteria and Pseudomonas aeruginosa.
Case report: We present here a case of venous catheter-related cutaneous infection in a man with immunosuppression, which was surprisingly caused by a rare environmental fungus, named Nigrograna chromolaenae. The therapeutic strategy combining posaconazole and removal surgery appears to have been effective, with no relapse more than 2 months after surgery.
Conclusions: Due to advances in molecular biology techniques, it is possible that infections with Nigrograna spp. will be increasingly described. At the moment the reported cases are few in number, and the treatment is not yet standardized, which is why we thought this new case could support the literature about these opportunistic pathogens.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
