Concatenate 5 string at once

Good afternoon

I've found that:

char * sSS;
String stringThree = String(sSS);

works... outside from a Switch...

Inside a switch case, I have the following error:

1>c:\arduino\arduinoIDE\sketches\CODINO_vsAddIn/..\CODINO1.pde: In function 'void GestaoMenus()':
1>c:\arduino\arduinoIDE\sketches\CODINO_vsAddIn/..\CODINO1.pde:685: error: jump to case label
1>c:\arduino\arduinoIDE\sketches\CODINO_vsAddIn/..\CODINO1.pde:652: error: crosses initialization of 'String stringThree'
1>c:\arduino\arduinoIDE\sketches\CODINO_vsAddIn/..\CODINO1.pde:688: error: jump to case label
1>c:\arduino\arduinoIDE\sketches\CODINO_vsAddIn/..\CODINO1.pde:652: error: crosses initialization of 'String stringThree'

Can somebody try to help me? Please.
I can't imagine why don't works inside a switch...

Thanks on advance
Best regards
