[Bhupinder Kaur, MD]

Hello,
On the sun exposed areas of the arms and legs porphyria cutanea tarda may cause blisters and skin fragility and erosions. Because of trauma it is also a site for epidermolysis bullosa and localized bullous pemphogoid is another possibility which should be ruled out.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
