A 50-year-old man with diabetes has a swollen, red, warm right foot without a wound; the foot has become flattened and deformed, and sensation is reduced in both feet. He is afebrile. What is most likely?

1. Charcot foot
2. Ankle sprain
3. Simple cellulitis
4. Chronic gout

Answer: A) Charcot foot. In diabetes with neuropathy, a hot, red, swollen foot without a wound and changing shape indicates Charcot foot, needing immobilisation and off-loading to prevent deformity.
