What is the diagnosis?

Neuropathic ulceration

What are the predisposing factors?

Minor trauma in a patient that has underlying diabetes mellitus, which has resulted in neuropathy and arteriolar ischaemia.

What are the clinical features of this condition?

Diabetes accounts for 15-25% of leg ulcers, and for the majority of chronic foot ulcers. Symptoms of sensory neuropathy include pain, paraesthesia and anaesthesia. Signs include:

Warm, dry foot with palpable pulses
Reduced response to light touch and painful stimuli distally.
Loss of ankle jerk reflex

In response to pressure, the skin of the sole, toe or heel increases in thickness (callus) but with a minor injury breaks down and ulcerates. The most common sites are the soles, metatarsal head, great toe (bunion) or heel. These ulcers are frequently secondarily infected.
