Abstract
Human fungal diseases are infections caused by any fungus that invades human tissues, causing superficial, subcutaneous, or systemic diseases. Fungal infections that enter various human tissues and organs pose a significant threat to millions of individuals with weakened immune systems globally. Over recent decades, the reported cases of invasive fungal infections have increased substantially and research progress in this field has also been rapidly boosted. This review provides a comprehensive list of human fungal pathogens extracted from over 850 recent case reports, and a summary of the relevant disease conditions and their origins. Details of 281 human fungal pathogens belonging to 12 classes and 104 genera in the divisions ascomycota, basidiomycota, entomophthoromycota, and mucoromycota are listed. Among these, Aspergillus stands out as the genus with the greatest potential of infecting humans, comprising 16 species known to infect humans. Additionally, three other genera, Curvularia, Exophiala, and Trichophyton, are recognized as significant genera, each comprising 10 or more known human pathogenic species. A phylogenetic analysis based on partial sequences of the 28S nrRNA gene (LSU) of human fungal pathogens was performed to show their phylogenetic relationships and clarify their taxonomies. In addition, this review summarizes the recent advancements in fungal disease diagnosis and therapeutics.

Antifungal susceptibility of the endophytic fungus Rhinocladiella similis (URM 7800) isolated from the Caatinga dry forest in Brazil. Braz J Microbiol 2022; 53:2093-2100. [PMID: 36152271 PMCID: PMC9679080 DOI: 10.1007/s42770-022-00825-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Accepted: 08/26/2022] [Indexed: 01/13/2023] Open
Abstract
The present study reports a new occurrence of Rhinocladiella similis isolated as an endophytic fungus in the Caatinga dry tropical forest in Brazil and describes its antifungal susceptibility. The isolate R. similis URM 7800 was obtained from leaves of the medicinal plant Myracrodruon urundeuva. Its morphological characterization was performed on potato dextrose agar medium and molecular analysis using the ITS rDNA sequence. The antifungal susceptibility profile was defined using the Clinical and Laboratory Standards Institute (CLSI) protocol M38-A2. The colony of isolate URM 7800 showed slow growth, with an olivaceous-gray color and powdery mycelium; in microculture, it showed the typical features of R. similis. In the antifungal susceptibility test, isolate URM 7800 showed high minimal inhibitory concentration (MIC) values for amphotericin B (>16 μg/mL), voriconazole (16 μg/mL), terbinafine (>0.5 μg/mL), and caspofungin (>8 μg/mL), among other antifungal drugs. Pathogenic melanized fungi are frequently isolated in environments where humans may be exposed, and these data show that it is essential to know if these isolates possess antifungal resistance.

Abstract
BackgroundDue to more attentions paid to melanized fungi over the past few decades and under the background of the global coronavirus disease 2019 pandemic (COVID-19) the fact that the virus itself and the immunosuppressive agents such as glucocorticoids can further increase the risk of infections of deep mycoses, the number of patients with phaeohyphomycosis (PHM) has a substantial increase. Their spectrum is broad and the early diagnosis and treatments are extremely sticky. This study aims to more comprehensively understand the clinical features of phaeohyphomycosis in China over 35 years and to establish a more applicable systematical classification and severity grades of lesions to guide treatments and prognosis.MethodsWe reviewed 174 cases of proven phaeohyphomycosis reported in Chinese and English language literature from 1987 to 2021 and we also made the accurate classification definitions and detailed information about the epidemiology, species of clinical dematiaceous fungi, minimum inhibitory concentration values, clinical features, treatments, and prognosis.ResultsThe mortality of cerebral, disseminated and pulmonary phaeohyphomycosis are 55%, 36%, and 25%. Nearly 19% of patients had poor quality of life caused by the complications such as disability, disfigurements, and blindness. The overall misdiagnosis rate of phaeohyphomycosis was 74%. Moderate to severe rashes are accounting for 82% of subcutaneous phaeohyphomycosis. The areas of the head and face are mostly affected accounting for 16% of severe rashes. Nearly 30% of invasive infections of phaeohyphomycosis are triggered by recurrent lesions. Voriconazole, itraconazole, amphotericin B deoxycholate (AmB-DOC), and terbinafine were most commonly used but diagnosis and treatments of phaeohyphomycosis remain challenging in reality.ConclusionsOur classifications are likely to be more practical and easier to popularize, and there are still also plenty of characteristics in these non-specific lesions. There’re no significant variations in cure rates, or death rates between three grades of lesions. But patients with severe rashes have longer courses and lower effective rates.

Successful Terbinafine Treatment for Cutaneous Phaeohyphomycosis Caused by Trematosphaeria grisea in a Heart Transplanted Man: Case Report and Literature Review. Mycopathologia 2020; 185:709-716.

Abstract
Phaeohyphomycosis is a chronic infectious disease caused by dematiaceous fungi. It is characterized by the presence of pigmented septate mycelia within tissues. In the case of superficial infection, the lesion(s) chronically evolve(s) toward painless pseudo-tumor(s) of the soft parts. We report herein the original case of a heart transplanted man who exhibited phaeohyphomycosis of the left hand, with no mention of travels in endemic areas. Trematosphaeria grisea was identified as the causative agent, which is quite innovative since this species has been rather described in mycetoma. The antifungal treatment initially based on isavuconazole alone was not sufficient to cure the patient. In contrast, its association with local terbinafine ointment allowed total clinical improvement. This finding is unusual as diagnosis of phaeohyphomycosis caused by T. grisea is uncommon in nontropical countries, and as the outcome appeared successful by the means of add-on therapeutic strategy with terbinafine.

Abstract
Photodynamic therapy (PDT) is a process that combines a photosensitizing drug and light and promotes phototoxic responses in target cells, mainly via oxidative damage. Antifungal photodynamic therapy has been successfully employed against Candida species, dermatophytes, and deep mycoses. We present a case of a cutaneous granuloma caused by C. albicans treated with 5-aminolevulinic acid (ALA)-PDT. A 64-year-old man presented with two plaques on his right hand and wrist for 2 years. The diagnosis was made based on histopathology, mycology, and molecular identification of paraffin-embedded tissues. The patient was treated with itraconazole for 1 month and two sessions of ALA-PDT. After 2 months of follow-up, the patient was cured and has not experienced any recurrence to date. ALA-PDT was well tolerated in this patient with little pain. In general, application of PDT in mycoses is safe and effective in most cases. ALA-PDT is a good choice for inactivation of C. albicans.

Abstract
Pheohyphomycosis is an uncommon infection and its association in spondylodiscitis has not yet been reported. The purpose of this case report is to describe a rare case of Pheohyphomycotic spondylodiscitis and methods to diagnose and manage the patient with less invasive techniques. A 29-year-old male patient presented to the outpatient department with complaints of gradually increasing low back pain with bilateral lower limbs radicular pain since one and a half years. He had associated fever, weight loss, voice changes, and dry, scaly, erythematous skin with elevated ESR. The patient had been taking anti-Koch's therapy since 1 year with little relief in pain and no radiological improvement. Percutaneous pedicle biopsy of L4 vertebra was taken under local anaesthesia and confirmed Pheohyphomycosis which was treated with antifungal medications. The patient showed sequential improvement with long term antifungal treatment. He was eventually able to walk independently without support.

Abstract
Rhinocladiella, a genus of black yeast-like fungi, is related to many infections in humans, including not only mild cutaneous lesions but also fatal brain infections. However, endophthalmitis caused by Rhinocladiella has never been reported by far. Herein, we present the first case of endophthalmitis due to Rhinocladiella basitona. The diagnosis was based on histopathology, mycology, and molecular identification. A 53-year-old female was struck by a piece of wood in her right eye. The wound in the central cornea became an ulcer and was aggravated continuously. Hyphae were found in the corneal scraping smear. Then endophthalmitis occurred and could not be controlled by the combined intravitreal antibiotic injections and vitrectomy. Finally, penetrating keratoplasty combined with retinal reattachment surgery was performed. Topical and systemic antifungal agents were administered for more than 1 month. The patient was cured, with improved visual acuity and clear corneal graft.

Abstract
Black yeast-like fungi and relatives as agents of cerebral phaeohyphomycosis are often encountered in human fatal brain abscesses and lead to almost 100% mortality despite the application of antifungal and surgical therapy. We report to our knowledge the first case of brain infection due to Rhinocladiella mackenziei in a 54-year-old immunocompetent male in Iran where R. mackenziei has not been reported previously. The initial diagnosis was brain fungal infection because of pigmented, irregular, branched, septated hyphae based on histopathological staining. The patient was treated with intravenous amphotericin B deoxycholate (0.5mg/kg/day) combined with oral itraconazole (200mg twice daily), nevertheless, his neurological function deteriorated rapidly and ultimately the patient died due to respiratory failure later two weeks. R. mackenziei was identified based on the sequencing of internal transcribed spacer (ITS rDNA region) (KJ140287). Therefore, considerable attention for this life-threatening infection is highly recommended.
