Chromoblastomycosis caused by Fonsecaea monophora in Mexico.

Chromoblastomycosis is a chronic subcutaneous fungal infection caused by melanized fungi. It is usually an occupational mycosis affecting people in rural areas in tropical and subtropical regions. We present two cases of chromoblastomycosis in Mexican farmers, characterized by skin verrucous plaques.

Fusarium subglutinans: A new eumycetoma agent.

Eumycetoma is a chronic subcutaneous mycosis mainly caused by Madurella spp. Fusarium opportunistic infections in humans are often caused by Fusarium solani and Fusarium oxysporum. We report a case of eumycetoma by F.

Epidemiological data and molecular characterization (mtDNA) of Sporothrix schenckii in 13 cases from Mexico.

Background: Sporotrichosis is an endemic mycosis in Mexico and Central America.

Objectives: To present epidemiological data and characterize molecular subtypes of 13 strains of Sporothrix schenckii, and to correlate clinical and epidemiologic presentation with subtypes.

Methodology: Thirteen Mexican cases of sporotrichosis were identified, and mitochondrial DNA (mtDNA) from clinical isolates of S.

Sporothrix schenckii type 3D (mtDNA-RFLP): report of an osteoarticular case.

Sporotrichosis is a frequent subcutaneous mycosis in Mexico and lymphocutaneous cases are the most common type. Extracutaneous or disseminated forms are exceptional and are usually seen in immunosuppressed hosts. We report the case of a 74-year-old immunocompetent male with osteoarticular involvement.

Chloracne in the 1990s.

Background: Chloracne is a disease associated with toxicity of halogenated compounds used in some industrial processes. A patient affected by chloracne led us to study a total of nine cases from a single factory.

Methods: We studied the clinical features of nine patients exposed chronically to chlorobenzenes.
