A mild form of Proteus syndrome.

Abstract

Proteus syndrome is a rare congenital hamartomatous syndrome. We report on the clinical and radiological appearances of a boy in order to illustrate the typical signs which include subcutaneous masses, in mild forms partial gigantism of hands and feet, hemihypertrophy, and bony abnormalities. We discuss how to make the definitive diagnosis on the basis of using a known rating scale, important aspects of differential diagnosis and clinical features, and diagnostic management.
