The current lesion is gangrene of skin with variable deep tissue involvement. It may due to various toxins released at the time of bite. Rule out diabetes. Start broad spectrum antibiotics. Debridement of all unhealthy tissue and pus till healthy tissue is seen. Regular dressings. As tendons will be exposed, full thickness skin graft / cross over flap will be required to prevent contracture on joint area.
