[Infantile cortical hyperostosis (Caffey's disease)].

A 3-month old infant was found to suffer from a solid painless soft tissue swelling situated in his left scapular region and accompanied by pronounced anaemia and raised erythrocyte sedimentation rate. The ominous clinical course as well as X-ray pictures of the scapula gave rise to a suspicion of a malignant tumour development. Biopsy from the surface of the bone gave no unambiguous answer. A histological examination of the whole surgically removed shoulder blade revealed the presence of infantile cortical hyperostosis.
