PUVA-induced acrobullous dermatosis is characterized by the occurrence of blisters on the acral extremities during PUVA therapy. The tense blisters apparently arise as a result of PUVA damage to the epidermodermal cohesion coupled with friction or trauma. They must be distinguished from phototoxic reactions induced either by UVA over-dosage or excessive psoralen uptake. We report on, two cases of acrobullous PUVA-induced dermatosis, discussing clinical features, pathophysiological aspects and differential diagnosis.
