[Tumor-like bone lesions in sternocostoclavicular hyperostosis and palmoplantaris pustulosis].

We present two unusual cases of sternocostoclavicular hyperostosis (SCCH) in conjunction with palmoplantar pustulosis (PPP) and additional tumour like manifestations in a scapula and a femur respectively. The association of SCCH with complexes of signs and symptoms such as chronic multifocal osteomyelitis (CRMO), or other nosological entities such as seronegative spondylarthropathies, is discussed.
