Crown vessels comprise linear, curved vessels with minimal branching, situated along the periphery and extending toward the center without crossing it, giving the appearance of a crown[1].




Differential diagnosis
Crown vessels are characteristic of sebaceous hyperplasia; this pattern was seen in 83.3% of sebaceous hyperplasia with a PPV of 83.3%[2]. Crown vessels may also be seen in molluscum contagiosum [3].
