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 revealed one novel 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 3 men from Ethiopia who were seen and are being treated by American doctors who traveled there on a medical mission...

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...

Pheohyphomycosis is a rare heterogeneous group of mycotic infections caused by dermatiaceous (phaeoid) fungi affecting the skin, subcutaneous tissue, and the central nervous system.Involvement of the face is extremely rare, and very few cases have been reported in India so far. We reporta case of phaeohyphomycosisin a 45-year-old female with 1-year history of a well- defined hypertrophic plaque over the right cheek advancing towards the forehead. The lesion was ulcerated with rolled-up margins; a provisional clinical diagnosis of basal cell carcinoma was given...

BACKGROUND: There is a worrying lack of epidemiological data on the geographical distribution and burden of subcutaneous mycoses in Peru, hindering the implementation of surveillance and control programs. OBJECTIVES: This study aimed to estimate the disease burden of subcutaneous mycoses in Peru and identify which fungal species were commonly associated with these mycoses. METHODS: We performed a meta-analysis after a systematic review of the published literature in PubMed, LILACS, and SciELO to estimate the burden of subcutaneous mycoses in 25 regions in Peru...

Phaeohyphomycosis is an unusual granulomatous fungal infection, observed in immunocompromised or diabetic patients; however, it is even rarer in immunocompetent patients. Cytological findings of the same have been infrequently reported. The histopathological diagnosis or fungal culture helps in definitive diagnosis to identify the exact fungal species. Hereby, we report a rare case of invasive fungal infection in a breast lump in a young female, presenting as fibroadenoma breast. Fine needle aspiration cytology from the breast lesion showed the presence of septate acute-angled branching fungal hyphae with focal pigmentation, morphologically suggestive of phaeohyphomycosis which was positive with fungal stains...

Veronaea botryosa has been identified as a pathogen of cultured white sturgeon Acipenser transmontanus. In 2015, samples from 19 white sturgeon were received for diagnosis, of which 14 cultured positive for V. botryosa. Intraspecific variability among V. botryosa isolates from different clinically affected hosts and geographic regions was investigated using repetitive extragenic palindromic PCR fingerprinting (rep-PCR). The rep-PCR profiles of 16 V. botryosa isolates from a human, sea turtles, and cultured fish were distinct from those of other phaeoid fungi belonging to the genera Cladophialophora and Exophiala...

Many previously unrecognized fungi are emerging as potential pathogens. One such group is dematiaceous fungi of the Chaetomiaceae family (phylum Ascomycota, class Sordariomycetes). These fungi are rare causes of opportunistic, neurotropic phaeohyphomycosis in humans but are not known to cause similar infections in animals. The aims of this study were to investigate equine hyphal mycotic encephalitis, characterize key histopathologic features, and classify causative organisms with molecular diagnostic techniques...

Understanding deep cutaneous fungal infection requires not only reading many case reports and checking the typical clinical images of skin lesions, but also managing the patients properly to prevent misdiagnosis. Herein, I review my recent experiences with eight typical cases of deep cutaneous infections (including protothecosis and nocardiosis) in Japan. It is very important to do the four management processes; namely, KOH direct microscopic examination, skin biopsy, fungal culture, and microscopic examination of the histopathological specimen of PAS and Grocott staining...

Subcutaneous phaeohyphomycosis is a form of infection caused by dematiaceous fungi and frequently reported in the literature. It is considered as an emerging mycosis because it is increasingly reported among immunosuppressive patients. The most commonly cited etiologic agent is Exophiala jeanselmei, followed by Alternaria spp. We present a case of a 48-year-old woman, with a history of lepromatous leprosy, using corticosteroid in immunosuppressive doses due to a type 2 repetitive reaction leprosy outbreak, revealing subcutaneous phaeohyphomycosis lesions...

This case report and literature review underscores the cutaneous presentations of phaeohyphomycosis in the solid organ transplant population. Increased cognizance with prompt identification is critical. The therapy and clinical outcomes of phaeohyphomycosis, caused by the Exophiala genus, in the solid organ transplant population, is analyzed to examine optimal care. This review highlights the inherent difficulties in providing the appropriate duration of antifungal therapy to avoid relapsing infections in immunosuppressed patients...
