He was a Thai worker living in Korea, and without specific traumatic event, he had the asymptomatic eythematous papule for 12 months. Therefore, besides the host cells regularly present in infected tissues, pedroski cells that are recruited to the sites of infection are key elements in the immune response to subcutaneous mycoses Hayakawa et al.
