AB0775 MANY RARE AND SERIOUS LOCALIZATIONS IN ONE CASE WITH HEREDITARY EXOSTOSES

Background: Multiple hereditary exostoses (MHE) is an inherited disorder of bone growth. People who have MHE grow or boney bumps on their bones that vary in size, location and number. Some localizations are rare but potentially serious such as ribs, spine pelvis due to proximity important structures. Objectives: The aim this case report was illustrate the clinical radiographic features some MHE. Methods: We reporting a thirty one-year-old male with severe Results: A affected by multiple exostoses., not followed up, came our consultation complaining about chest pain. On examination, he walks limp because unequalness his limbs.The osteoarticular examination revealed numerous palpable osseous masses at distal proximal end 2 arms, forearms, thighs legs right iliac wing. Neurological vivid deep tendon reflexes, bilateral positive Hoffmann’sign Babinski reflex associated hemiparesis. pulmonary exam normal. Medullary MRI showed medullary compression spinal cord atrophy sign myelopathy c1 c2 segment. ct –scan exostosis, two largest lesions were located second rib measuring 45mm * 35mm axially 52mm height compromising blood vessels, retroperitoneal growing mass 126 94 mm 100 leading entrapment axial skeleton abdominal organs. It also confirmed thickening cartilage cap suggestive malignant chondrosarcomatous transformation. Conclusion: Exostoses most common benign tumors. Its complications can cause functional disability even vital risk. References: [1]Eke GK, Omunakwe HE, Echem RC. Hereditary 15-year-old boy: review literature. Niger J Paediatr. 2016;43(4):295.
