A healthy 1-month-old boy attended for evaluation of lesions on his back that had been present since birth. He had no relevant family history. On examination, he had pink plaques on his back with central bluish colouration and depression and some prominent ectatic vessels, surrounded by a dusky halo (image 1). The plaques were soft, poorly compressible, painless, and more prominent during crying. Musculoskeletal examination was normal, as were blood count, liver enzymes, renal function, and coagulation.
