An otherwise healthy 12 year old boy presents to your clinic for evaluation of a “bump” on his left anterior shoulder/axilla. His parents report that he was born with a small bruise that they assumed was secondary to birth trauma. The bruise never went away and the area has grown with him over time.

B Venous malformation​

Based on the history and exam, this lesion is most consistent with a venous malformation. It has been present since birth and grown with the patient over time. Venous malformations are often somewhat compressible. This lesion empties with pressure and will refill when pressure is released. Many venous malformations will have an overlying bluish tinge to the skin.
