Abstract
BACKGROUND Facial cutaneous sporotrichosis presents with diverse clinical manifestations, often leading to misdiagnosis. OBJECTIVE This study aims to present the clinical characteristics of five misdiagnosed cases of facial cutaneous sporotrichosis, aiming to enhance understanding of this disease and prevent misdiagnosis and mistreatment. METHODS Clinical data, histopathology, and fungal culture results of these five cases were comprehensively analyzed. RESULTS Among these five patients, three presented with lymphocutaneous sporotrichosis, while two had the fixed cutaneous type. Due to misdiagnosis, initial treatments were ineffective for all patients. Upon histopathological examination and fungal culture confirming sporotrichosis, treatment with itraconazole for 3 months led to complete resolution of lesions. While one patient experienced a relapse due to noncompliance with the prescribed medication. CONCLUSION Facial sporotrichosis, with its diverse clinical manifestations and obscure trauma history, is prone to misdiagnosis. Timely and thorough examinations are crucial for precise diagnosis and management. Itraconazole treatment demonstrated notable efficacy, and patient compliance is also essential for favorable outcomes.

[PMID: 38667958 PMCID: PMC11051268 DOI: 10.3390/jof10040287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2024] [Revised: 04/03/2024] [Accepted: 04/11/2024] [Indexed: 04/28/2024] Open
Abstract
Zoonotic sporotrichosis, a subcutaneous mycosis caused by Sporothrix brasiliensis, has become hyperendemic and a serious public health issue in Brazil and an emerging disease throughout the world. Typical sporotrichosis is defined as fixed or lymphocutaneous lesion development, however, reports of atypical presentations have been described in hyperendemic areas, which may result in a worse prognosis. Thus, considering an increase in atypical cases and in more severe extracutaneous cases and hospitalizations reported in Brazil, we aimed to perform a systematic review to search for hypersensitivity reactions (HRs) and extracutaneous presentations associated with zoonotic sporotrichosis. A systematic review was performed, following the PRISMA guidelines to search for atypical/extracutaneous cases (mucosal, osteoarthritis, HRs, pulmonary, meningeal) of zoonotic sporotrichosis. A total of 791 published cases over 26 years (1998-2023) in eleven Brazilian states were reviewed. Most cases corresponded to a HR (47%; n = 370), followed by mucosal (32%; n = 256), multifocal (8%; n = 60), osteoarthritis (7%; n = 59), meningeal (4%; n = 32), and pulmonary (2%; n = 14) infections. When available (n = 607), the outcome was death in 7% (n = 43) of cases. Here, we show a frequent and worrisome scenario of zoonotic sporotrichosis in Brazil, with a high and dispersed incidence of atypical/extracutaneous cases throughout the Brazilian territory. Therefore, educational measures are necessary to make health professionals and the overall population aware of this fungal pathogen in Brazil as well as in other countries in the Americas.

Abstract
PURPOSE OF REVIEW Invasive fungal infection (IFI) in children is a growing problem with crescent morbidity and mortality, well recognized in developed countries, affecting mainly immunocompromised children, including neonates and children in intensive care units. The burden of IFI in South American children is less well comprehended. In addition, the current epidemiology of endemic systemic mycoses in children may have changed over time. RECENT FINDINGS Candida spp. infections are very prevalent in South America hospitalized children, especially in neonates, in a rate far superior compared to developed countries. C. auris, has already been responsible for outbreaks in neonates and children in Venezuela and Colombia. Sporotrichosis is well established as an urban zoonosis in impoverish families. Paracoccidioidomycosis and histoplasmosis are affecting new areas of Brazil, probably due to climate change, deforestation, and human migration. SUMMARY This review aims to unveil the real dimension of these infections in South American children. Hopefully, the awareness brought by this review will help healthcare professionals to recognize IFI more easily and it will provide support for getting more resources for IFI treatment and prevention.

Abstract
Sporotrichosis is a rare type of fungal infection caused by Sporothrix fungus. Transmissions are commonly by traumatic inoculation of the fungus through the skin and subcutaneous tissue either from environmental exposure or contact with infected animals. Due to its mode of transmission, it is commonly affecting the upper limbs. Definitive diagnosis can be obtained by fungal culture test on secretion fluids, pus, bloods or tissue biopsy. We report a rare presentation of this disease appearing as a solitary chronic ulcer of the lip which was successfully treated with itraconazole.

Abstract
Introduction Sporotrichosis is an implantation mycosis caused by Sporothrix spp. It is distributed worldwide and can be found in vegetation and soil. The most frequent route of infection is by trauma with elements contaminated with fungal propagules. Since domestic cats are the most affected animals and can transmit this infection to humans, sporotrichosis is considered a zoonosis. Clinical presentations include nodular lymphangitis, fixed cutaneous, pulmonary (rare), and disseminated (exceptional). Objectives To analyze the epidemiology of sporotrichosis in Argentina during 2010 and 2022. To describe the clinical presentation, diagnostic methods, and treatment of cases diagnosed during this period. To know the circulating genotypes and to observe possible associations with the geographic location where the infection was acquired. Materials and methods Analytical, retrospective, and observational study. We analyzed the medical records of patients with sporotrichosis from 12 health institutions in Argentina, between 2010 and 2022. Results We present 54 cases in which the most frequent clinical form was nodular lymphangitis, and the treatment of choice was itraconazole. Conventional diagnosis was made in all cases. Culture of clinical samples was more sensitive than direct examination because it allowed the isolation of Sporothrix spp. in all 54 cases. Molecular identification was performed in 22 cases, with Sporothrix schenkii sensu stricto being the most frequently isolated species. Conclusions This study allowed to know the epidemiology of this mycosis in Argentina, as well as the availability of diagnostic methods and the treatment of choice.

Abstract
Zoonotic outbreaks of sporotrichosis are increasing in Brazil. We examined and described the emergence of cat-transmitted sporotrichosis (CTS) caused by the fungal pathogen Sporothrix brasiliensis. We calculated incidence and mapped geographic distribution of cases in Curitiba, Brazil, by reviewing medical records from 216 sporotrichosis cases diagnosed during 2011-May 2022. Proven sporotrichosis was established in 84 (39%) patients and probable sporotrichosis in 132 (61%). Incidence increased from 0.3 cases/100,000 outpatient visit-years in 2011 to 21.4 cases/100,000 outpatient visit-years in 2021; of the 216 cases, 58% (n = 126) were diagnosed during 2019-2021. The main clinical form of sporotrichosis was lymphocutaneous (63%), followed by localized cutaneous (24%), ocular (10%), multisite infections (3%), and cutaneous disseminated (<0.5%). Since the first report of CTS in Curitiba in 2011, sporotrichosis has increased substantially, indicating continuous disease transmission. Clinician and public awareness of CTS and efforts to prevent transmission are needed.

Abstract
Ocular infections associated with sporotrichosis can present four clinical manifestations: granulomatous conjunctivitis, dacryocystitis, Parinaud oculoglandular syndrome, and bulbar conjunctivitis. The incidence of ocular sporotrichosis related to zoonotic transmission has significantly increased in endemic regions and is a frequently misdiagnosed cause of granulomatous conjuntivitis. Therefore, we present a series of seven cases of eye injury by Sporothrix strains, including clinical forms, therapeutic approaches, and laboratory procedures to alert health professionals who provide care to these patients.

Abstract
BACKGROUND Cat-transmitted sporotrichosis (CTS) caused by Sporothrix brasiliensis has emerged as an important zoonosis in Brazil and neighboring countries. OBJECTIVES Evaluate the performance of a lateral flow assay (LFA) for the detection of anti-Sporothrix antibodies in human sera. METHODS A LFA for the detection of anti-Sporothrix antibodies (Anti-Sporo LFA) in human sera, developed by IMMY, was evaluated using 300 human sera collected prospectively at the Hospital de Clínicas, Federal University of Paraná (HC-UFPR), in Curitiba, Brazil. These specimens included 100 sera from patients with CTS. CTS cases were classified as: 59 lymphocutaneous, 27 fixed cutaneous,13 ocular, and one mixed form. One-hundred specimens from patients with other mycoses, including cryptococcosis (n=32), candidemia (n=27), paracoccidioidomycosis (n=14), aspergillosis (n=10), histoplasmosis (n=9), fusariosis (n=4), lobomycosis (n=1), chromoblastomycosis (n=1), mucormycosis (n=1), and trichosporonosis (n=1). And 100 specimens from apparently healthy volunteers (AHV). RESULTS The Anti-Sporo LFA showed a global sensitivity of 83% (95% confidence interval [CI] = 74%-90%), a global specificity of 82% (95% CI = 76%-87%), and accuracy of 82% (95% CI = 77%-86%). By clinical form sensitivity was as follows: Mixed form 100%, ocular 92%, lymphocutaneous 83%, and fixed cutaneous 78%. False-positive results were observed in 11 specimens from people with other mycoses and 26 specimens from AHV. CONCLUSION-DISCUSSION This study presents the results of the evaluation of the first lateral flow assay for the detection of anti-Sporothrix antibodies in human sera. The findings here show evidence that IMMY´s Anti-Sporo LFA is a promising tool for the rapid diagnosis of CTS.
