Flashcards in Benign tumours of bone Deck (28):
1

cartilage capped bony projection on external surface of bone containing a marrow cavity that is continuous with the underlying bone

osteochondroma

2

what age do osteochondromas occur in. where. symptoms. rx

under 20
near epiphyses of long bones
pain and irritation despite being benign
surgical removal

3

chondrocytes with small round pyknotic nuclei inside hyaline cartilage

chondroma aka enchondroma

4

benign hyaline cartilage tumour arising in medullary cavity of bones of hands and feet

chondroma

5

what are the different kinds of chondroma

if single then just chondroma
if multiple then can be olliers disease or maffuccis disease

6

presentation of olliers disease. FH? malignant risk?

unilateral and involving extremity
not familial or hereditary
malignant transformation is 10-25%

7

presentation of maffuccis. malignant?

multiple endochondromas with soft tissue and visceral haemongiomas
greater risk of malignant transformation compared to olliers

8

core is vascular osteoid tissue and peripheral zone is sclerotic bone

osteoid ostoma

9

who does osteoid stoma occur in and where

young adults and children. M>W
femur, tibia, hands, feet, spine

10

presentation and treatment of osteoid ostoma

dull pain worse at night. relieved within 20-30 mins by NSAIDs or aspirin
resolves in 33 months without treatment

11

what kind of tumour is chondroblastoma, who and where

cartilage tumour with an aggressive coarse
teens
epiphyses of long bones

20

presentation and treatment of osteoid ostoma

dull pain worse at night. relieved within 20-30 mins by NSAIDs or aspirin
resolves in 33 months without treatment

21

spherical well defined osteolytic foci which can erode into joints and its cell borders have chicken wire calcification

chondroblastoma

22

what kind of tumour is chondroblastoma, who and where

cartilage tumour with an aggressive coarse
teens
epiphyses of long bones

23

what is a simple bone cyst and why does it arise

single benign fluid filled cavity
growth defect

24

what are aneurysmal bone cysts and what are some of the symptoms

lots of chambers filled with blood or serum due to arteriovenous malformation
cortical expansion and painful

25

what is shepherds crook deformity

proximal femur angulated due to fibrous dysplasia

26

who does fibrous dysplasia occur, what does the bone look like and what is the treatment

adolescents
wide with thinner cortisol
bisphosphonates

27

brodies abscess associated with

subacute osteomyelitis

28

brown tumours associated with

hyperparathyroidism
