Een pasgeborene met een rood-paarse zwelling

A 2-week-old male infant was seen with a congenital swelling on his leg. Physical examination revealed an upper leg with a warm to the touch, red-purple tumour of approximately 3 x 2 cm containing telangiectases. The skin around the tumour was pale. Eight weeks later the tumour had regressed. Based on the clinical characteristics and the course, we made the diagnosis ‘rapidly involuting congenital hemangioma’ (RICH).
