ABSTRACT
Chromoblastomycosis is a chronic infection, caused by pigmented fungi affecting skin and subcutaneous tissues characterized by verrucous nodules or plaques. Fonsecaea pedrosoiand Cladophialophora carrionii are the prevalent agents in the endemic areas. Phoma is an uncommon agent of human infection and involved mainly with phaeohyphomycosis cases. The case of a patient with a history of laceration in foot followed by verrucous aspect and scaly lesions, which had evolved for 27 years is presented. On physical examination disease was clinically compatible with chromoblastomycosis and the microscopic examination of scales showed fumagoid cells. On culture a dematiaceous fungus was grown. The agent was confirmed to be Phoma insulana based on its morphology and PCR-sequencing. This fungal agent has not been previously reported in association with this pathology (AU)
La cromoblastomicosis es una infección crónica causada por hongos pigmentados que afecta la piel y el tejido subcutáneo y que se caracteriza por nódulos o placas verrugosas. Fonsecaea pedrosoi y Cladophialophora carrionii son los agentes prevalentes en las áreas endémicas. Phoma es un agente raro de infección humana y está involucrado principalmente en casos de feohifomicosis. Se presenta el caso de un paciente con antecedente de laceración en el pie, seguida de lesiones de aspecto verrugoso y descamativas, que evolucionaron durante 27años. En el examen físico la enfermedad fue clínicamente compatible con cromoblastomicosis y el examen microscópico de escamas mostró células fumagoides. En el cultivo creció un hongo dematiáceo. El agente fue confirmado como Phoma insulana en base a su morfología y PCR seguida de secuenciación. Este agente fúngico no ha sido reportado previamente en asociación con esta patología (AU)
