Dermoscopic approach for differential diagnosing of autoimmune bullous disease: pemphigus vulgaris, pemphigus foliaceus, and IgA pemphigus.

Dermoscopy is an important tool that serves as a link between clinical and histopathological diagnoses, and it can easily be used in daily practice. Several suggestive dermoscopic features can help in the differential diagnosis of autoimmune bullous disease but only after making a provisional clinical diagnosis. Dermoscopy is a very useful tool in the differentiation of pemphigus subtypes.
