What type of ulcer is caused by decreased cutaneous sensation and is commonly associated with diabetes mellitus?

The correct answer is a neuropathic ulcer, which is specifically associated with conditions that impair sensation, such as diabetes mellitus. In individuals with diabetes, high blood sugar levels can lead to peripheral neuropathy, a condition that damages nerves and diminishes the ability to feel pain, temperature, and touch in the extremities. This loss of sensation means that minor injuries, blisters, or pressure points may go unnoticed and can develop into ulcers.

Neuropathic ulcers typically occur on areas of the foot that bear weight or experience friction, where the skin has become damaged due to lack of sensation. Without proper care and attention, these ulcers can become severe and lead to infections, hospitalization, and even amputation in extreme cases.

While other types of ulcers such as pressure ulcers and venous ulcers also represent significant medical concerns, they do not arise from the specific mechanism of decreased cutaneous sensation that is characteristic of neuropathic ulcers in individuals with diabetes. Pressure ulcers are usually related to prolonged pressure on the skin, and venous ulcers are often caused by improper functioning of venous valves leading to poor blood return rather than sensory loss. The diabetic foot ulcer is a broader term that may include neuropathic ulcers but is specified to diabetic patients, focusing more on
