Invasive fungal disease (IFD) confers a substantial risk for morbidity and mortality to immunocompromised patients. Invasive aspergillosis (IA) is the most common IFD caused by moulds but the prevalence of other rare mould diseases, such as mucormycosis, hyalohyphomycosis, and phaeohyphomycosis, may be increasing. Treatments are available for IA but evidence to support efficacy and safety of antifungal agents for rare IFDs, or for IFDs in special patient populations, is limited or lacking. The VITAL trial was conducted to assess the efficacy and safety of isavuconazole for treatment of patients with IA and renal impairment, or with IFDs caused by rare moulds, yeasts or dimorphic fungi...

Black yeasts (BY) comprise a group of polyextremotolerant fungi, mainly belonging to the order Chaetothyriales, which are capable of colonizing a wide range of extreme environments. The tolerance to hostile habitats can be explained by their intrinsic ability to survive under acidic, alkaline, and toxic conditions, high temperature, low nutrient availability, and osmotic and mechanical stress. Occasionally, some species can cause human chromoblastomycosis, a chronic subcutaneous infection, as well as disseminated or cerebral phaeohyphomycosis...

Cerebral phaeohyphomycosis is an infection caused by a number of dematiaceous fungi, characterised by the presence of melanised hyphae in the invaded tissue. Cladophialophora bantiana is the most common species affecting the humans, which has a predilection for causing the central nervous system infections resulting in high mortality. We hereby report a success story of two cases of brain abscess caused by C. bantiana who were treated with surgical source reduction and voriconazole therapy.

Veronaea botryosa is a melanized mold and cause of systemic fungal infections in cultured sturgeon (Acipenser spp.). Mortality in adult female sturgeon caused by this emergent pathogen results in significant economic losses for the caviar industry. Little is known regarding environmental conditions conducive to V. botryosa infection. This study evaluated the effect of temperature on V. botryosa infectivity and dissemination following intramuscular injection challenge of white sturgeon maintained at 13 or 18 °C for 40 days...

Phaeohyphomycosis is a fungal infection caused by Dermatiacae group of fungi, by Cladosporium spp. The term phaeohyphomycosis was introduced by Ajello et al. in 1974 to designate infections by brown pigmented filamentous fungi. Cladosporium oxysporum is a very rare etiological agent in humans. Phaeohyphomycosis of the cervical lymph node in an immunocompetent individual is a very rare clinical entity. To the best of our knowledge we report the first case of phaeohyphomycosis caused by Cladosporium oxysporum in the absence of other systemic manifestations in a 16-year-old male...

Cerebral phaeohyphomycosis is frequently a fatal disease caused by truly neurotropic dematiaceous fungi. Although rare, this infection occurs especially among immunocompetent patients, and the clinical symptoms are often misdiagnosed as a cerebral tumour or bacterial brain abscess. The appropriate diagnosis and therapy of cerebral infections by melanized fungi are very challenging if they are caused by mysterious fungi with unknown ecological niche. We reported the second case of cerebral phaeohyphomycosis due to Rhinocladiella mackenziei in Iran and the first culture-confirmed case...

Phialophora as defined by its type species P. verrucosa is a genus of Chaetothyriales , and a member of the group known as 'black yeasts and relatives'. Phialophora verrucosa has been reported from mutilating human infections such as chromoblastomycosis, disseminated phaeohyphomycosis and mycetoma, while morphologically similar fungi are rather commonly isolated from the environment. Phenotypes are insufficient for correct species identification, and molecular data have revealed significant genetic variation within the complex of species currently identified as P...

Invasive fungal disease is a serious infectious complication of allogeneic hematopoietic stem cell transplantation (HSCT). Exserohilum rostratum is a species causing phaeohyphomycosis, which rarely causes invasive disease in humans. We treated a case of sinusitis caused by E. rostratum after cord blood transplantation (CBT). A 60-year-old man with myelodysplastic syndrome, who had a medical history of an operation to correct deviation of the nasal septum, developed sinusitis caused by E. rostratum under prolonged profound neutropenia after a second CBT because of the graft rejection of the first transplantation...

Phaeohyphomycosis is a group of severe infections caused by dematiaceous fungi. We previously identified CARD9 deficiencies in four Chinese patients with phaeohyphomycosis caused by Phialophora verrucosa. In this study, we sought to identify the genetic and immunological mechanisms underlying rare dematiaceous fungal infections in three otherwise healthy patients with phaeohyphomycosis caused by Exophiala spinifera, Ochroconis musae, and Corynespora cassiicola. CARD9 sequencing in these patients showed one mutation (p...

Subcutaneous phaeohyphomycosis is a chronic fungal infection usually found on the lower extremity and feet of agricultural workers in the tropics. It can present with various skin manifestations, verrucous to nodular plaques, and is caused by multiple species of fungi. Laboratory confirmation requires skin samples for pathology and fungal cultures. Cure, often difficult in resource-poor countries, requires months of antifungal therapy. We describe the cases of three men from Ethiopia who were seen and are being treated by American doctors who traveled there on a medical mission...

A 35-year-old woman with severe cystic fibrosis was admitted for sudden loss of strength in both legs, revealing a myelitis. The medullary lesion biopsy revealed phaeohyphomycosis caused by Cladophialophora species. Myelitis caused by Cladophialophora bantiana is a rare disease associated with high mortality.

BACKGROUND: Superficial and deep fungal infections are more frequent in transplant recipients primarily because of the failure of cell-mediated immunity and lesser amount of antigen-presenting Langerhans cells in their epidermis. Here, we report seven cases of post-renal transplant subcutaneous phaeohyphomycosis, all of which manifested within 1 year after transplantation and were unresponsive to prolonged courses of itraconazole. This is the first case series, to our knowledge, of phaeohyphomycosis in transplant recipients in India...

There are very few reports of pediatric patients with infections by dematiaceous filamentous fungi. In this publication we report a case of invasive fungal infection of the nasal septum by Curvularia spicifera in a pediatric patient with acute myeloid leukemia. The patient presented with a painful scabby wound in the nasal vestibule. Culture and universal PCR were consistent with Curvularia spicifera. Early management with surgical debridement and bi-associated antifungal therapy achieved complete resolution of the lesions, with no evidence of dissemination and relapses...

Phaeohyphomycosis (PHM) is a term used to describe any fungus presenting in tissues with pseudohyphae, hyphae, brown yeast-like cells or a combination of these forms. Sinusitis and skin infections are the most common presentation of subcutaneous PHM caused by the fungus Bipolaris spicifera. However, the majority of cases have so far been encountered in tropical climatic zones. The present study documents a case of subcutaneous PHM caused by infection with Bipolaris spicifera in a 56-year-old Chinese man, who presented with plaque papillomatosis on the left foot...
