Infections with Scedosporium and Lomentospora species, in particular Lomentospora (previously Scedosporium) prolificans, are nearly universally fatal and rapidly-progressive in the transplant population. We report a case of a patient with diffuse large B-cell lymphoma undergoing myelosuppressive chemotherapy who developed disseminated L. prolificans infection which afterward persisted in his knee joint. The infection was treated with early empiric triple antifungal therapy tailored to synergy studies, growth factors to quickly resolve neutropenia, and aggressive debridement (where possible) of infection sites, including amputation. He achieved an 11-month remission until undergoing autologous hematopoietic stem cell transplantation with deep myelosuppression, wherein recrudescent L. prolificans infection occurred, causing death. We highlight the importance of early treatment, synergy studies, and especially recovery of neutropenia in treating this devastating condition.

Background: While invasive fusariosis and lomentosporiosis are known to be associated with fungemia, overall data on mold-related fungemia are limited, hampering early management. This study aimed to describe the epidemiology of mold-positive blood cultures.
Methods: Epidemiological and clinical data on mold-positive blood cultures from 2012 to 2022 were obtained from the RESSIF database.

A 59-year-old female with anti-MDA5 antibody-positive dermatomyositis was treated with prednisolone, tacrolimus, cyclophosphamide, tofacitinib, and plasma exchange. Five months post-treatment, elevated β-D-glucan levels and a pulmonary shadow on CT were noted. was identified, leading to voriconazole initiation.

Article Synopsis
- Dematiaceous molds are dark environmental molds found worldwide, particularly in tropical and subtropical areas, with common types including Bipolaris, Cladophialophora, Exophiala, and Alternaria.
- These molds can cause a variety of diseases in both healthy and immunocompromised individuals, leading to issues like skin infections, allergic reactions, pneumonia, and sometimes serious systemic infections.
- Treatment generally involves antifungal medications such as itraconazole, voriconazole, or posaconazole, combined with measures to address the source of infection and reduce immune suppression, while efforts are underway to enhance diagnostic methods and treatment options due to high mortality rates associated with severe cases.

is a filamentous fungus with a global distribution, manifesting particularly higher prevalence in human-impacted environments. This organism is associated with a wide spectrum of human infections, especially in immunosuppressed individuals, for whom it causes severe and debilitating illnesses with high morbidity and mortality that are compounded by its pan-resistant profile with respect to antifungal drugs. Melanin is a ubiquitous pigment among fungi with a broad range of actions that include promoting fungal virulence.

There is clearly a need for novel antifungal agents, not only concerning spectrum, but also oral bioavailability, tolerability, and drug-drug interactions. There is growing concern for antifungal resistance for current available antifungals, mainly driven by environmental fungicide use or long-term exposure to antifungals, in the setting of mould-active prophylaxis or for chronic antifungal infections, such as chronic pulmonary aspergillosis. Moreover, the incidence of breakthrough infections is increasing, because of the introduction of (mould-active) prophylaxis (1-4).
