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. Direct examination with KOH 10% showed the presence of muriform cells. The fungal isolation was carried out in Sabouraud dextrose agar and molecular identification was achieved by 18S-ITS1-5.8S-ITS2-28S rRNA gene amplification and sequencing. Fonsecaeamonophora was identified in both cases. A therapy with itraconazole and terbinafine was used with a partial favorable response. However, patients did not return for medical examination after 4 months. The current status of the patients is unknown. We reported the first two cases of chromoblastomycosis caused by F. monophora in Mexico.
