Occurrence of nasal, cutaneous and disseminated rhinosporidiosis in the same patient is uncommon and involvement of calcaneum is rare. Rhinosporidial osteomyelitis is treated surgically, but multiple recurrences and local spread are common. Many a times, surgical ablation or amputation of the involved area of the limb is carried out to prevent recurrences. We present a case of rhinosporidial osteomyelitis of the calcaneum with a chronic discharging sinus and large lytic lesion in the calcaneum treated by an alternative surgical option in the form of debridement and negative pressure wound therapy.
