[Destructive diaphysitis in early congenital syphilis]

X-ray observations of bone lesions produced by Syphilis Connata Praecox have been reviewed. 15 cases of this condition are presented of which six show mucous and cutaneous lesions. One planus condylomata; three cases of pemphigus, one with paronychia; one perionixis and one rhinitis. Bone lesions appeared in X-ray observations in all cases excepting one in which lesions had already reacted to therapy. Concerning these 15 cases of Syphilis Connata Praecox we consider important to inform about X-ray discoveries both frequent and infrequent concerning this condition. We point out one exceptional case of destructive diaphysitis associated with a typical metaphyseal osteolysis.
