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. [PMID: 32562177 DOI: 10.1007/s11046-020-00467-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Accepted: 06/06/2020] [Indexed: 01/19/2023]
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
We report a rare case of subcutaneous phaeohyphomycosis caused by Cladophialophora bantiana in an immunocompetent patient in Amazonas, Brazil. This dematiaceous fungus has been mainly associated with life-threatening infections affecting the central nervous systems of immunosuppressed patients. We present the clinical, laboratory, and therapeutic aspects, and in vitro susceptibility test results for different antifungal drugs. A brief review of the cases reported in the literature over the past 20 years has also been discussed. According to the literature review, the present case is the first report of subcutaneous phaeohyphomycosis due to C. bantiana in an immunocompetent patient in Latin America.

Abstract
Cladophialophora bantiana is a phaeoid fungus that only rarely has been isolated from sources other than the human brain. It has a particular tropism for the central nervous system (CNS). We have integrated and updated large-scale data related to several aspects of C. Bantiana and reviewed all the available reports on its cerebral infections, focusing on their geographical distribution, infection routes, immune status of infected individuals, type and location of infections, clinical manifestations and treatment and outcome, briefly looking over the spectrum of other disease entities associated with C. bantiana, that is, extra-cerebral and animal infections and on the environmental sources of this fungus. Among the agents of phaeohyphomycosis, a term used to describe an infection caused by a dark pigmented fungus, C. bantiana has some significant specific features. A total of 120 case reports were identified with a significantly higher percentage of healthy subjects than immune-debilitated patients (58.3% vs. 41.7%). Infections due to C. bantiana occur worldwide. The main clinical manifestations are brain abscess (97.5%), coinfection of brain tissue and meninges (14.2%) and meningitis alone (2.5%). Among immunocompetent patients, cerebral infection occurred in the absence of pulmonary lesions. The mortality rate is 65.0% regardless of the patient's immune status. The therapeutic options used include surgery or antifungals alone, and the combination of both, in most cases the fatal outcome being rapid after admission. Since the fungus is a true pathogen, laboratory workers should be made aware that BioSafety Level-3 precautions might be necessary.

Abstract
Cladophialophora bantiana, a dematiaceous fungus from the family Phaeohyphomycetes, is highly neurotropic and primarily reported as a rare cause of brain abscess. Pulmonary infection and disease outside the central nervous system is extremely rare, particularly in immunocompetent patients. We report an unusual case of disseminated cladosporiosis in a young man with a new diagnosis of prediabetes but no other identifiable risk factors for disease. Fungal cultures were positive for C. bantiana from brain abscess aspiration, vertebral bone cultures and subcarinal lymph node biopsy. Although the patient demonstrated initial good response to surgical debridement of brain abscesses plus antifungal therapy, he eventually expired from septic shock secondary to C. bantiana pneumonia and recurrent brain abscesses 2 years after initial diagnosis.

Abstract
BACKGROUND Among dematiaceous fungi responsible for phaeohyphomycosis, Cladophialophora bantiana is an opportunistic pathogen that causes central nervous system infections, chiefly in immunocompromised patients. Only a few reports on skin involvements have been reported in the recent dermatological literature. Herein we report the case of an immunocompetent patient with cutaneous phaeohyphomycosis. CASE REPORT A 48-year-old male presented a nodular, painless and non-suppurative lesion with a diameter of 1cm on the right buttock that had developed since his return from a trip to Vietnam. A diagnosis of phaeohyphomycosis due to C. bantiana was made based on the histopathology and mycology examinations, which allowed the identification of C. bantiana, a dematiaceous (black) fungus from hyphomycete species. DISCUSSION C. bantiana is a neurotropic fungus that causes central nervous system infections in particular. Extracerebral involvement is rare and only a few cases of cutaneous phaeohyphomycosis have been reported. Furthermore, since immunocompromised hosts are more vulnerable, this mycosis is more commonly seen in immunocompromised patients. However in this particular case, an intramuscular injection of corticosteroids could have caused local immunosuppression. The prognosis depends on both localization and site. There are no guidelines for optimal treatment.

Abstract
Melanized or dematiaceous fungi are associated with a wide variety of infectious syndromes, including chromoblastomycosis, mycetoma, and phaeohyphomycosis. [corrected]. Many are soil organisms and are generally distributed worldwide, though certain species appear to have restricted geographic ranges. Though they are uncommon causes of disease, melanized fungi have been increasingly recognized as important pathogens, with most reports occurring in the past 20 years. The spectrum of diseases with which they are associated has also broadened and includes allergic disease, superficial and deep local infections, pneumonia, brain abscess, and disseminated infection. For some infections in immunocompetent individuals, such as allergic fungal sinusitis and brain abscess, they are among the most common etiologic fungi. Melanin is a likely virulence factor for these fungi. Diagnosis relies on careful microscopic and pathological examination, as well as clinical assessment of the patient, as these fungi are often considered contaminants. Therapy varies depending upon the clinical syndrome. Local infection may be cured with excision alone, while systemic disease is often refractory to therapy. Triazoles such as voriconazole, posaconazole, and itraconazole have the most consistent in vitro activity. Further studies are needed to better understand the pathogenesis and optimal treatment of these uncommon infections.
