Abstract
Sterno-costo-clavicular hyperostosis is a disease of unknown origin. We tried to clarify the relationship in it between dermatological symptoms and hyperostosis changes of the sternocostoclavicular region by evaluating clinical courses and radiological findings in 30 of 112 house cases over 1 to 12 years (average 5.3 years) . The cases, 9 male and 22 female, ranged in age from 26 to 74.
The arthrotic symptoms were pain in 43%, swelling in 20%, local fever in 23.3% and ossif ical protrusion in 73%. The dermatological symptoms were classified into 3 types. There were 17 cases of transient type, 7 cases of recurrent type, and 6 cases of continuous type. Of the osteotic changes, 20% were negative, 36.7% atrophic, 20% hypertrophic, 50% sclerotic and 16.7% cystic. The artrophic changes were negative in 53.3%, narrow in 16.7% and irregular in 26.7%, and had fused in 23.3%. In bone scintigraphy, a strong uptake was found especially in irregular, fused and sclerotic types. The relationship between sternocostoclavicular hyperostosis and Pustulosis Palmaris et Plantaris (P.P.P.) was that the more severe the clinical symptoms were the greater the trend to dermatological disorders, especially in the continuous type. This suggested that the symptomatic courses of sternocostoclavicular hyperostosis and P.P.P. have a positive association.
