aka- osteogenic sarcoma
- Metastatic are the MC malignancy of the bone → they are lytic
- Lytic = radiolucencies on x-rays

recurrent acute rheumatic endocarditis can lead to___
mitral incompetence
• Mitral valve: has vegetation lying along the valve closure
→ the vegetation is fibrin and platelet deposition
Mitral Incompetence with recurrent acute rheumatic endocarditis
- Rounded polypoid and gelatinous tumor
* Arising from the interatrial septum → below the fossa ovalis (mesenchymal origin)
left atrial myxoma
-MC primary cardiac tumor
MC primary cardiac tumor
left atrial myxoma

Complications: • edema • phlebitis • thrombosis • stasis dermatitis (cutaneous ulceration)
occlusive impaction of any material in the pulmonary arterial system
MC location:

pulmonary embolism
pre-disposing factors: • post-partum • post-surgery • bed rest • hypercoagulability
pumonary embolism
Fatal: sudden death→ R. heart failure
- consolidation of the basal portion of the lower lobe and patchy consolidation of the middle lobe

- Grey hepatization (4-8 days)
- Resolution (8-10 days)
Complications:
• bacteremia
• Abscess
• Pulmonary fibrosis
- large bronchiectatic cavities = coagulative material
