A 14-year-old female presented with an erythematous soft crusted nodule over the scalp [Figure 1]. Dermoscopy was performed using dermlite II hybrid m dermoscope at 10 × magnification in polarized mode and photographs were captured by Apple IPhone 6. Dermoscopy revealed homogenous reddish area with white rail lines surrounded by white collarette with ulceration [Figure 2], suggestive of pyogenic granuloma. Histopathology revealed lobular capillary proliferation in upper dermis (Hematoxylin and Eosin 100×) [Figure 3].

Pyogenic granuloma is dermoscopically characterized by homogeneous reddish or white-red areas surrounded by a whitish collarette in up to 85% of the cases. The areas correlate with the histologic finding of proliferating capillaries and veins, whereas the collarette corresponds to the epidermal collarette that often surrounds the proliferation of blood vessels in pyogenic granuloma. White lines correspond to the histologic finding of fibrous septa that surround the lobules.
