An 18-month-old boy presented by his mother with a “lump” above his eye. You see this lump as shown in the picture. The child is described by his mother as “perfectly healthy”. She states that she just noticed this, but in retrospect she thinks that it could have been present for several months at least. You eye examination confirms that the child’s eyes are normal. The mass is firm to palpation but can be moved slightly under what appears to be normal skin and is softer than “rock hard”.
