How do bullous lesions typically present in less severe cases?

1. Large painful blisters

2. Severe chronic blistering

3. Blisters in response to minor trauma

4. Non-healing skin ulcers

The correct answer is: Blisters in response to minor trauma

In less severe cases, bullous lesions often present as blisters that form in response to minor trauma. This means that the skin may not be greatly compromised, and the formation of blisters is typically associated with benign activities or mild physical irritants. When the skin integrity is only slightly affected, the bullous lesions can develop due to situations such as friction or pressure, which can provoke localized blistering without severe underlying skin disease. This presentation indicates that the body’s response is relatively low in severity, and the blisters may resolve on their own without requiring extensive medical intervention. This distinguishes it from more severe cases where blistering can be chronic or caused by more significant underlying conditions, which might involve systemic issues or conditions like pemphigus or toxic epidermal necrolysis, leading to more extensive and painful blistering or non-healing ulcers.
