Called "PlayStation palmar hidradentitis" by the scientists, the skin disorder can cause painful lesions on the palms similar to patches found on the soles of children's feet after taking part in heavy physical activity, they said.
"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 and colleagues at University Hospitals and Medical School of Geneva reported in the British Journal of Dermatology.
A spokesman for Sony Corp, which makes the PlayStation, noted the study involved one person and said the company had sold hundreds of millions of the consoles since the product was introduced in 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.
"We would not wish to belittle this research and we will study the findings with interest, but this is the first time we have ever heard of a complaint of this nature." He further explained.
