ewings sarcoma
malignant tumour that occurs most frequently in the diaphysis of the pelvis and long bones- onion skin
chondrosarcoma
malignant tumour of cartilage, which most commonly affects the axial skeleton and not the diaphysis of long bones. This type of tumour is also more common in middle-age.
Giant cell tumour
This is a benign tumour of multinucleated giant cells which occurs most frequently in the epiphyses of long bones and shows a ‘double-bubble’ or ‘soap bubble’ appearance on x-ray. more commonly seen in patients aged 20-40 years old.
Osteochondroma
most common benign bone tumour and while it is most in males aged under 20 years old, it often presents with cartilage-capped bony projection on the external surface of a bone
Osteosarcoma
This is the most common primary malignant bone tumour and while it also is seen mainly in children and adolescents, it occurs most frequently in the metaphyseal region of long bones prior to epiphyseal closure. It also shows a ‘sunburst’ pattern on x-ray and is most commonly associated with mutations in the retinoblastoma gene (and hence retinoblastoma tumours).
What to do if alendronate cannot be tolerated

Management of myasthenic crisis

Management of ascites

unfractionated heparin with bailout glycoprotein IIb/IIIa inhibitor (GPI) if radial access used
