Global distribution patterns of Cladophialophora carrionii, agent of human chromoblastomycosis in arid climates of Africa, Asia, Australia, Central-and South-America, were compared with similar data of the vicarious Fonsecaea spp., agents of the disease in tropical rain forests. Population diversities among 73 C. carrionii strains and 60 strains of three Fonsecaea species were analyzed for rDNA ITS, partial β-tubulin, and amplified fragment-length polymorphism (AFLP) fingerprints. Populations differed significantly between continents. Lowest haplotype diversity was found in South American populations, while African strains were the most diverse. Gene flow was noted between the African population and all other continents. The general pattern of Fonsecaea agents of chromoblastomycosis differed significantly from that of C. carrionii and revealed deeper divergence among three differentiated species with smaller numbers of haplotypes, indicating a longer evolutionary history.

Chromoblastomycosis is an uncommon, chronic granulomatous fungal infection of the skin and subcutaneous tissue. Chromoblastomycosis is most commonly caused by the traumatic inoculation of dematiaceous (pigmented) fungi, most commonly species, species, and species. Chromoblastomycosis usually affects agricultural workers in tropical and subtropical climates.

This is the case of chronic chromoblastomycosis (CBM) in a 61-year-old male from the Dominican Republic (DR) with extensive cutaneous eruptions over multiple areas of the body including bilateral lower extremities and the flank extending to the back. A 61-year-old male with a history of morbid obesity, chronic kidney disease stage III, and well-controlled hypertension presented to the family medicine clinic for the evaluation of chronic painful skin lesions on his legs and torso. The lesions began 19 years prior, following a flood in the Dominican Republic (DR) where he was living at the time.

Chromoblastomycosis is a skin infection caused by melanized fungi that primarily affects rural workers. This study aimed to analyze the clinical and epidemiological manifestations of chromoblastomycosis in Brazil through an extensive literature review. A review of case reports or series of cases in English and Portuguese was conducted using the SciELO, LILACS, SCOPUS, PubMed, and Web of Science databases from 1963 to 2022.

Chromoblastomycosis, an implantation mycosis, is a neglected tropical disease that causes decreased quality of life, stigma, and disability. The global burden of disease is unknown and data on disease epidemiology and outcomes are severely limited by a lack of access to needed diagnostic tools and therapeutics. The World Health Organization outlined targets for chromoblastomycosis in the Road Map for Neglected Tropical Diseases 2021-2030, but little progress has been made in initiating and implementing an effective control program globally.
