Correct answer: D — Pyogenic granuloma

Pyogenic granuloma (lobular capillary haemangioma) presents as a rapidly growing vascular nodule that bleeds easily with trauma. Dermoscopy shows a homogeneous red area (vascular proliferation) with a white collarette (epithelial collarette at the base). Reddish-white areas and intersecting white rails may also be seen. Although benign, pyogenic granuloma must be distinguished from amelanotic melanoma (which shows polymorphous vessels) and nodular BCC (arborising vessels). Excision with histological examination is recommended to confirm diagnosis. Recurrence after incomplete removal is common. In pregnancy, pyogenic granulomas are called granuloma gravidarum.
