1. Accuracy of direct examination and culture as compared to the anatomopathological examination for the diagnosis of chromoblastomycosis: a systematic review
Abstract Background: Chromoblastomycosis is a skin infection caused by dematiaceous fungi that take the form of muriform cells in the tissue. It mainly manifests as verrucous plaques on the lower limbs of rural workers in tropical countries. Objectives: The primary objective of this review is to evaluate the accuracy of diagnostic methods for the identific

2. Presence of hyphae in chromoblastomycosis examinations: an enigma to be solved
Abstract The detection of muriform cells in direct mycological or anatomopathological examination is considered pathognomonic for chromoblastomycosis. The morphological aspect that these fungal structures acquire were called “Borelli spiders”, when associated with hyphae. Reports of this association have been described for decades, initially related to m

3. Case for diagnosis. Pruritic erythematosquamous lesion in the auricle,
Abstract Chromoblastomycosis is a subcutaneous mycosis with chronic evolution that mainly affects the lower limbs and, less frequently, the auricles. Clinically, it presents with papillary verrucous, nodular, and/or tumoral lesions, whether isolated or infiltrated, forming plaques and, sometimes, atrophic in some areas. Histopathologically, it is characteriz

4. Chromoblastomycosis caused by Rhinocladiella aquaspersa: first case report in Guatemala
Abstract The authors report a case of 40-year-old male patient with a five-year history of chromoblastomycosis on his right leg. Diagnosis was performed by direct 40% KOH exam of skin scales, culture with micro- and macromorphologic analysis, and genotypic characterization (sequencing of a fragment of the ITS region and phylogenetic analysis) of the isolated

6. Synergistic effect of terbinafine and amphotericin B in killing Fonsecaea nubica in vitro and in vivo
ABSTRACT Chromoblastomycosis is a chronic fungal infection. Itraconazole and terbinafine are the most recommended antifungal drugs for chromoblastomycosis, while amphotericin B is not usually recommended. A patient with chromoblastomycosis in our hospital showed poor clinical responses to itraconazole and terbinafine. The fungus isolated from the lesions o

7. Study of tissue inflammatory response in different mice strains infected by dematiaceous fungi Fonsecaea pedrosoi
Abstract: Background: Diseases caused by melanized fungi include mycetoma, chromoblastomycosis and phaeohyphomycosis. This broad clinical spectrum depends on the dynamic interactions between etiologic agent and host. The immune status of the host influences on the development of the disease, as, an exemple. phaeohyphomicosis is more frequently observed in i

8. Chromoblastomycosis: an etiological, epidemiological, clinical, diagnostic, and treatment update
Abstract: Chromoblastomycosis is a chronic, granulomatous, suppurative mycosis of the skin and subcutaneous tissue caused by traumatic inoculation of dematiaceous fungi of the family Herpotrichiellaceae. The species Fonsecaea pedrosoi and Cladophialophora carrionii are prevalent in regions where the disease is endemic. Chromoblastomycosis lesions are polymor

9. Melanin particles isolated from the fungus Fonsecaea pedrosoi activates the human complement system
BACKGROUND Melanin production has been associated with virulence in various pathogenic fungi, including Fonsecaea pedrosoi, the major etiological agent for chromoblastomycosis, a subcutaneous fungal disease that occurs in South America. OBJECTIVE The aim of this study was to evaluate the effects of acid-basic extracted F. pedrosoi melanin particles and fun

11. Chromoblastomycosis: tissue modifications during itraconazole treatment
Abstract: Background: Histological and mycological changes during itraconazole use have not been totally established in chromoblastomycosis. Objectives: To evaluate tissue modifications in chromoblastomycosis carriers under itraconazole treatment. Methods: A histological retrospective study of 20 cases of chromoblastomycosis seen at the university hospita

12. Response of chromoblastomycosis to voriconazole
Abstract: Chromoblastomycosis is a chronic fungal infection of the epidermis, dermis and subcutaneous tissue, in which the most common etiologic agent in Brazil is Fonsecaea pedrosoi. In more advanced cases we found many difficulties in their treatment, and therefore, we report a case of extensive and severe chromoblastomycosis, with therapeutical failure of
