Help!! Mosaic Wart

KDC

Has anybody had problems with Mosaic Warts? About 5yrs ago my son had what I thought was a verucca on his big toe. It got bigger and bigger. Dr said to leave it, it'll got away on its own. It got bigger. Tried all the wart and verucca stuff from chemist, they did nothing.

It now covers the underneath and top of his toe and down the inside right up to his nail. He's almost 12 and its extremely unsightly. The last thing Dr told us was it's actually a Mosaic Wart and to soak it in famaldahyd (sorry its spelt wrong) for 15mins each day. Given how huge it is and where it is this was extremely difficult as he's not a contortionist. We went back to Dr yet again who still says it'll go away on its own.

When he's in bare feet the wart gets hard and can be painful when pressed. Dr says its far too big to freeze off and it would be very painful to cut it off - especially for a child.

Does anybody have any suggestions for getting rid of this please?? Tonight it appears to be spreading to the toe next to his big one!!

Thanks for any ideas. He's quite upset about it
