Subcorneal pustular dermatosis--an unusual course.
In a patient with subcorneal pustular dermatosis (SPD) the appearance of new pustular lesions characteristic of the disease was triggered by two episodes of drug eruption (induced by dapsone and quinidine sulphate respectively) and by the intra-dermal injection of the recall antigens Candida and streptokinase-streptodornase, performed for evaluation of delayed hypersensitivity. Both episodes of drug eruption were probably the result of an immediate-type hypersensitivity reaction towards the offending drugs, as indicated by positive mast cell degranulation tests.
