Rapp Review Flashcards
Intramuscular myxoma
spindle cells with a myxoid background
Radiation can “HELP”
- hemangioepithelioma
- ewing’s
- primary Lymphoma of bone
- plasmacytoma
2:13 translocation
alveolar rhabdomyosarcoma translocation
*think “2 lungs”
12:16 translocation
myxoid liposarcoma
sarcomatous degeneration of a giant cell tumor
can occur ~5 years after initial resection, will clearly see malignant appearing histology
needs a wide resection and reconstruction, and also chemo
chondrosarcoma treatment is:
reserction
NO chemo and NO resection
treatment of synovial sarcoma
responsive to chemo and radiation for local control
CREAS requires lymph node biopsies
- clear cell sarc
- rhabdomyosarc
- epithelioid sarc
- angiosarcoma
- synovial sarcoma
Stage III PTTI
rigid hindfoot valgus, rigid forefoot abduction
gets a triple arthrodesis
Difference between stage IIA and IIB PTTI?
A= normal forefoot B= forefoot abduction
soft tissue sarcomas that need chemo:
- rhabdomyosarcoma
- synovial sarcoma
- dedifferentiated liposarc
- pleomorphic liposarc
- myxoid/round cell liposarc
If you think ABC, make sure it is not
Telangiectatic osteosarcoma
- looks similar but for the presence of malignant appearing cells in the pathology
mnemonic for small round blue cell tumors (LERNEM)
LERNEM Lymphoma Ewing's Rhabdomyosarcoma Primitive Neuroectodermal tumor Myeloma
if you see multiple lucent lesions in the femoral head epiphysis, think:
chondroblastoma in a kid
clear cell chondrosarc in an adult
Post-radiation fracture rate and risk factors (following soft tissue sarcoma):
25-30%
- female
- radiation dose
- weight bearing bones
- periosteal stripping during resection
- age
