A 12-year-old Swiss girl has developed intensely painful lesions on her hands after playing too many video games, according to a Geneva hospital.
"The tight and continuous grasping of the hand-grips together with repeated pushing of the buttons produce minor but continuous trauma to the (palm) surfaces," Vincent Piguet, a professor at Geneva University Hospital, reported in the British Journal of Dermatology.
The victim recovered after a ten-day break, it was reported.
Technology blogs and tabloids on Wednesday widely circulated news of the condition, identified as "PlayStation palmar hidradentitis".
Sony, the Japanese electronics company that makes the bestselling video game console, pointed out that it had sold hundreds of millions of the consoles since 1995.
"As with any leisure pursuit there are possible consequences of not following common sense, health advice and guidelines, as can be found within our instruction manuals," Sony spokesman David Wilson said.
Other people have reported tendonitis, broken bones and split lips after playing competitor Nintendo's console, the Wii.
