Pseudoporphyria is a blistering eruption,usually of the dorsal hands, which is triggered by an exogenous medication.  The most commonly implicated of the meds are the NSAIDs, although a whole host of others have been implicated- even aspirin!

The presentation is a blistering eruption on the dorsal hands, and the ddx is EBA, PCT and PseudoPCT.  Careful history will rule out PCT, and if there is a history of NSAID use in combination with sun exposure, you've got your culprit.

Ten days into April, we've got a three way tie for first, with a bunch of you one point behind.  Keep it up!
