Chronic Madura foot: Mycetoma and/or Actinomyces spp or actinomycosis

Abstract

A 58-year-old agricultural worker from a remote Western province farming community in Saudi Arabia presented with a 2-year history of right plantar foot soft tissue mass. According to the patient, the swelling had gradually increased in size over a few years, but it was painless and thus had not restricted him from continuing to farm until the lesion started to affect mobility. An MRI, microbiology and histopathology reported a rare infectious agent - Actinomyces spp, otherwise referred to as Madura foot. Three-dimensional CT aided in a preoperative surgical plan which included mass excision/debulking for this challenging lesion. Full eradication was not possible, and the patient required prolonged anti-infective therapy (>6 months) along with close surveillance to map resolution of infective symptoms.
