The SAPHO-syndrome: case report of an 18-year-old man and review of the literature

We report about an 18-year-old man, suffering from acne on his face and trunk and complaining about indefinite bone pains - without any trauma. SAPHO-syndrome was diagnosed which consists of synovitis, acne, pustulosis, hyperostosis and osteitis. Five types of this syndrome can be differentiated: spondarthritis hyperostotica pustulo-psoriatica, chronic recurrent multifocal osteomyelitis, inflammatory chest wall syndrome, isolated sternocostoclavicular hyperostosis, and the combined form of acne-associated spondarthritis and chronic recurrent osteomyelitis. Although the sapho-syndrome is very rare, it should be considered a possible diagnosis in the case of indefinite bone pains in combination with acne, pustulosis and hyperostosis.
