Dermoscopic and histological correlation of an atypical case of pyogenic granuloma.

Pyogenic granuloma (PG) is a common, rapidly growing, benign vascular proliferation of skin and mucous membranes generally showing, on dermoscopy, a typical pattern characterized by a red to dark pink homogeneous area surrounded by a white collarette. A case of PG in a 5-year-old girl showing an atypical dermoscopic pattern characterized by the presence of a central, irregular, whitish-yellow amorphous structure with a peripheral crown of polymorphous, atypical vessels is reported and discussed.
