Flashcards in Rapp Review Deck (18):
1

Intramuscular myxoma

spindle cells with a myxoid background

2

Radiation can "HELP"

- hemangioepithelioma
- ewing's
- primary Lymphoma of bone
- plasmacytoma

3

2:13 translocation

alveolar rhabdomyosarcoma translocation
*think "2 lungs"

4

12:16 translocation

myxoid liposarcoma

5

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

6

chondrosarcoma treatment is:

reserction

NO chemo and NO resection

7

treatment of synovial sarcoma

responsive to chemo and radiation for local control

8

CREAS requires lymph node biopsies

- clear cell sarc
- rhabdomyosarc
- epithelioid sarc
- angiosarcoma
- synovial sarcoma

9

Stage III PTTI

rigid hindfoot valgus, rigid forefoot abduction

gets a triple arthrodesis

10

Difference between stage IIA and IIB PTTI?

A= normal forefoot
B= forefoot abduction

11

soft tissue sarcomas that need chemo:

- rhabdomyosarcoma
- synovial sarcoma
- dedifferentiated liposarc
- pleomorphic liposarc
- myxoid/round cell liposarc

12

If you think ABC, make sure it is not

Telangiectatic osteosarcoma
- looks similar but for the presence of malignant appearing cells in the pathology

13

mnemonic for small round blue cell tumors (LERNEM)

LERNEM
Lymphoma
Ewing's
Rhabdomyosarcoma
Primitive Neuroectodermal tumor
Myeloma

14

if you see multiple lucent lesions in the femoral head epiphysis, think:

chondroblastoma in a kid
clear cell chondrosarc in an adult

15

Post-radiation fracture rate and risk factors (following soft tissue sarcoma):

25-30%
- female
- radiation dose
- weight bearing bones
- periosteal stripping during resection
- age

16

2;13 translocation

alveolar rhabdomyosarcoma

17

12;16

myxoid liposarcoma

18

Stain for well differentiated liposarcoma

MDM2/CDK4
