A cheeky grin etched across his face, 18-month-old Gavin loves to throw around his toys like any normal toddler.
But unlike most children his age, the brave boy has already battled a rare genetic condition which has left a glaring physical mark.
For Gavin bears a huge growth on his jaw after being born with hundreds of small cysts which bulge from under his skin.
A gruelling treatment process saw him spend the first seven months of his life in hospital, where he endured relentless injections and multiple operations.
Now, parents Joseph and Victoria Silvestri, from Jacksonville, Florida, have spoken out about Gavin's tough start with lymphatic malformation.

Yet this did not faze the delighted couple, who like any parents were overwhelmed with joy.
Ms Silvestri said: 'I wasn't crying, I wasn't upset, because that was him, that was my baby.'
But after just four days Gavin had to begin a long journey of sclerotherapy, which uses injections to target and shrink the cysts.
