Hematemesis and multiple exostoses in 12-years-old child: association or complication of exostosis?

Background: Exostosis or osteochondrome is a benign bone tumour affecting the extremity of a long bone.Multiple locations are possible, making an exostosis disease which is hereditary with a dominating
autosomic transmission.Case Report: The most reported complications in the literature are mechanic, of the muscular, nervous compression type, or with limitations of movements. We report on the comment of a boy followed up since he was 12 for multiple exostosis and who presented episodes of hematemesis.Conclusions: The hematemesis and exostosis disease association is little reported in the African literature. Hematemesis on our patient is probably related to the aggression of the digestive tract by chimical agents andor stress.
