[Dermatologic aspects of SAPHO-syndrome]

SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, osteitis) as a new disease entity was first described in 1987. The syndrome is characterized by the presence of pustular dermatoses together with aseptic osteoarticular lesions. The bone involvement includes hyperostosis, aseptic osteomyelitis or arthritis of the anterior chest wall, sacroiliac joints or long bones. Skin diseases include acne conglobata or acne fulminans, palmoplantar pustulosis and hidradenitis suppurativa. Authors describe the dermatological relationship of SAPHO syndrome reporting their 7 cases (3 acne fulminans, 4 palmoplantar pustulosis). Authors draw attention to the isotretinoin therapy as a possible provoking factor of the articular symptoms, and they emphasize the diagnostic role of bone scintigraphy.
