Bullous scabies mimicking bullous pemphigoid.

Scabies is an infestation caused by Sarcoptes scabiei and characterised by polymorphous lesions that may include burrows, papules, nodules, excoriation and crusts. Vesicular and bullous lesions are rather rare. Several diseases may be confused with scabies. We report a case of bullous scabies which, on the basis of the clinical and histopathological picture, mimicked bullous pemphigoid. Direct and indirect immunofluorescence were negative. Bullae recurred and persisted despite systemic corticosteroids. The patient was successfully treated with 5% permethrin and remained disease free for up to 12 months of follow-up.
