Researchers in Brazil documented seven cases of squamous cell carcinoma that resulted from chronic chromoblastomycosis in the Brazilian Amazon state Maranhão.
“There appears to be remarkable polymorphism in the presentation of [chromoblastomycosis] lesions, where the most aggressive and disabling manifestation is possible malignant transformation,” the researchers wrote in Clinical Infectious Diseases. “However, this extreme is considered rare by some authors, probably due to the lower number of reports to date. Here we demonstrate that malignancy may be more common in [chromoblastomycosis] than shown by current data.”
