neuroma

24
Q

t/f

sarcomas are rare

A

true

25
Q

t/f

sarcomas are more common in children than epithelial

A

true

26
Q

t/f

sarcomas commonly spread to the lymph nodes

A

false

lymphatic spread is very rare, if present unlikely to be sarcoma

27
Q

defining feature of sarcomas

A

local growth - can get fucking HUGE

28
Q

where can sarcomas spread to

A

blood - haematogenous spread

29
Q

features of sarcomas

A

single cell lesions
cigar shaped nuclei
solid looking

30
Q

t/f

sarcomas have a strong genetic link

A

true - use FISH and karyotyping to determine translocations

31
Q

myeloid cells are

A

red blood cells etc

32
Q

lymphoid cells

A

B cells, T cells, NK

33
Q

primary site of haematological tumours

A

NO PRIMARY ORGAN

34
Q

where do haematological tumours metastasise

A

they don’t

35
Q

what is lymphoma

A

tumour like mass in lymph nodes

36
Q

what is leukaemia

A

circulating malignant cells in blood and bone marrow with no mass

37
Q

what are the happens for haemangioma with bone marrow involvement

A

less RBCs, platelets, granulocytes and normal B cells

38
Q

what test must be done if a haematological tumour is suspected

A

FBC

39
Q

what if FBC comes back low

A

marrow involvement

40
Q

what if FBC high

A

abnormal cells

41
Q

what do haematological tumours look like

A

solid white masses, can often look quite similar (not pleomorphic)

42
Q

what is a neuroectoderm tumour

A

melanoma

43
Q

what are brain tumours known as

A

gliomas

44
Q

what are we thinking if we see lesions in the brain

A

secondary mets (carcinoma)

45
Q

what is hepatoma known as

A

hepatocellular carcinoma

46
Q

t/f

lesions in the brain are common

A

false, they are rare, mets more common

47
Q

why are tumours in the brain always seen as malignant

A

in an enclosed space so expansion will effect surrounding structure

48
Q

where do brain tumours metastasise to

A

no where

49
Q

why don’t primary brain tumours metastasise

A

due to the blood brain barrier (stay in brain)
