MSK Tumours Flashcards
most common adult malignancy
carcinoma
what are rhuematoid nodules
firm, non-tender lumps that commonly develop in people with rheumatoid arthritis
typically form subcutaneously
what is myosisitis ossificans
Abnormal calcification of a muscle haematoma following trauma
leads to ossified bone where it does not normally occur
symptoms of myositis ossificans
Pain and tenderness in the affected muscle or area.
Swelling and stiffness.
Decreased range of motion in the joint near the affected muscle.
In some cases, a palpable mass can develop as the condition progresses
what is myosiitis ossificans usually due to
post sporting injury
management of myositiis ossificans
rest, ice , NSAIDS
invesitagtions for myositis ossificans

what is nodular fascitis
benign (non-cancerous) soft tissue tumor that arises from the fascia, which is the connective tissue surrounding muscles, nerves, and blood vessels
nodular fascitis overview
any age group
smallish but rapid growth rate
chaotic appearance
reassurance as management
what is ewings sarcoma
primary bone tumour of endothelila cells of the bone marrow
who does ewings usually occur in
children
which bones in ewings usually seen in
long bones
management of ewings
removal of tumour and surrounding tissue, with joint reconstruction
what is an osteosarcoma
bone cancer usually affecting long bones
age goup osteosarcoma usually seen in
paediatrics and early adulthood
is osteosarcoma known to be aggressive
yes it can metastisize easily
name for benign skeletal tumour
rhabdomyoma
endochonroma overview
in cartilage
in the digits usually never maligannt
tends to not affect peads
leiomyoma overview
most common as smooth muscle is everywhere
often arse from large vessel walls
pigmented villonodular synovitis
PVNS
type of benign tumour in synovial tissue
more destructive
difficult to excise and can often recur

deep fibromatosis
characteristic xray finding of giant cell tumours
soap bubble appearance

mjore common in males
often diopathicn
genetic predisposition and environmental factors
pathophysiology of dupuyrtrens
- Excessive myofibroblast proliferation and altered collagen matrix composition leads to thickened and contracted palpar fascia
- The thickening and contracture of the subdermal fascia leads to fixed flexion deformity of fingers (NOT associated with a tendon)
- Bands are primarily collagen type III
surgery for dupuytrens
fasciotomy
