Sterno-kosto-klavikuläre Hyperostose^*

Abstract

A case is described in which bilateral subclavian vein occlusion was caused by fusiform expansion of the clavicle with hyperostosis, ankylosis of the sterno-clavicular joint, widening and thickening of the sternum and ossification of the costal cartilage of the first ribs. Histologically this proved to be due to an hyperostotic spongiosclerosis.

Pustular osteoarthropathy and its differential diagnosis

“…Pustular osteoarthropathy is characterised radiographically by hyperostosis, sclerosis and erosions of the clavicle and the adjacent parts of the manubrium. The differential diagnosis includes Paget's disease, chronic osteomyelitis, osteoid osteoma, tuberculosis, melorrheostosis, neurofibromatosis and Camurati-Engelmann disease [7]. The normal alkaline phosphatase, a negative tine test and the typical sites of the hyperostoses help in the diagnosis.…”

“…The cancellous bone does not show any significant cellular infiltration. Characteristic hyperostotic cancellous bone sclerosis has been described [7]. The condition is usually treated with anti-inflammatory drugs.…”
