Exogenous ochronosis plus subepidermal blister disease. Maybe the patient abused of hydroquinone for a subepidermal bullous skin disease like bullous lupus. Clinical history is very important.

Exogenous ochronosis, maybe a complication of antimalarial drug used for a photodermatitis.

The best word that describes this case is what Dr Carr said: a big WOW :-))) exogenous ochronosis... Possibly complicating hydorquinone.
