Mycetoma is a chronic, debilitating, granulomatous disease affecting the subcutaneous tissue, fascia, muscle, bone and adjacent organs characterized by triad of tumefaction, draining sinus, and grains. The ten-year incidence in our institution from 2000 to 2010 is 3 out of 81,015 cases. We present a 33-year-old man with a nine-year history of painless nodules and draining sinuses on the left foot which were unresponsive to oral antibiotics and topical antifungals. Biopsy of a nodule was consistent with mycetoma. Fungal culture revealed Madurella mycetomatis growth confirming eumycetoma. X-ray of the left foot showed poorly marginated lucencies on the calcaneus and navicular bones. Ultrasound revealed mixed hyperreflective echoes and multiple small cavities. We diagnosed the patient with Stage III eumycetoma based on the radiographic classification of bone involvement and prescribed oral ketoconazole 400 mg daily for nine months achieving 50-60% decrease in lesion size. Surgical debulking was done and ketoconazole was continued at the same dose for another nine months. There was good granulation tissue formation and no appearance of new lesions after surgery.
