Bone lesions in systemic acne (acne fulminans).
An 18-year-old West Indian male presented with severe sternal pain and an exacerbation of facial acne. Radiographs of the sternum revealed several lytic lesions which appeared as hot areas on successive technetium bone scans. Painful areas over the right iliac crest and left greater trochanter likewise appeared as transient hot areas on successive scans. Histology of affected bone revealed reactive changes only. High dose prednisolone provided rapid alleviation of pain, which recurred on reducing the dose to less than 10 mg daily. Auto-immune complex disease has been considered the most likely aetiological mechanism of systemic acne (acne fulminans), but lytic lesions of bone have never previously been reported in auto-immune disorders.
