[Plantar actinomycetoma in a patient without risk factors]

A case of plantar actinomycetoma without risk factors is presented, which was diagnosed by hystopatological analysis of a foot biopsy because of the suspicion of neoplasia. Since the patient did not fully respond to the first-line therapy antibiotics, a 24-weeks doxycycline regime was started, achieving a satisfactory response. Finally, a brief discussion on plantar mycetomas is presented.
