Q

If you have a CD 30+ MF what do you need to distinguish it from

A

1) systemic ALCL
2) CD30+ transformed MF
3) other times of CTCL which sometimes express CD30
4) reactive infiltrates eg viral infections, bites, scabies, AD, HIV or post transplant lymphoma

Q

Tx for LyP

A 
nothing 
MTX, dapsone
UVB
topical steroids
but will likely recur post
could try Radiotherapy 
need for long term FU due to risk of progression - FU 6/12

Q

Tx for C-ALCL

A

refer to exclude systemic

radiotherapy or low dose MTX or excision

24
Q

Types of indolent CTCL

A

MF, CD 30+ lymphoproliferative disease (anaplastic large cell lymphoma & LyP)
Subcutaneous panniculitis like T cell lymphoma, CD4+ small/medium pleomorphic T cell lymphoma.

25
B2
a clone which is the same as in the skin and >5% sezary cells or several fold increase in normal CD4:8 ratio, or increase in malignant cells as measured by CD26 or CD7 drop out
26
Stages III and IV
TSEBT, interferons, bexarotene, ECP | Vorinostat, romidepsin, denileukion diftitox
27
Bloods of sezary
B1>5% sezary cells on buffy coat smear | B2>20% total lymphocyte count or total sezary count of >1000x10^9
28
Dx of large cell transformation of MF
cells >4x size of a small lymphocytes and composing > 25%. More likely to occur in higher stages
29
Tx of follicuotrophic MF
less responsive to skin directed therapies PUVA, topical nitrogen mustard PUVA + IFN alpha or retinoids, local radiotherapy or TSEB
30
Clinical features of folliculotrophic MF
more aggressive AA like, classical type, lichen spinulosis type, infiltration in plques or tumorus. Acneiform, comedones, nodular prurigo like hair follicles pruritic, more severe, often secondarily infected
31
Risk of progression to MF in large plaque parapsoriasis
10-35%, 100% if retiform.
32
What is stage IB MF
>10% patches/plaques
33
Poor prognostic factors of MF
lymph node involvement | African American females
34
Associations with lymphocytoma cutis
borrelia, medications, vaccinations, metal implants, bites, tattoos
35
Clinical features of LyP
chronic, recurrent crops of self healing papulonecrotic or papulonodular skin disease red brown papules and nodules that may develop central haemorrhage, necrosis and crusting
36
Treatments for MF (general measures)
For itch: - emollietnts, topical steroids, soak and smear, wet dressings, opioids for dressing changes, trial an antihistamine. SSRIs: paroxetine, mirtazeapine, gabapentin, pregabaline, aprepitant Naloxone, Reduce infection risik bleach baths swab nasal mupirocin
37
histo of small plaque parapsoriasis
focal hyperkeratosis and parakeratosis | aggregates of morphologically normal CD4 TA cells.
38
What is the 5 year survival of tumour stage MF
50%
39
How to distinguish ALCL from systemic
Cutaneous: CLA+ve, EMA and ALK neg | opposite in systemic
40
What is stage IIB MF
tumour stage, may include nodes and blood involvement
41
What type of large plaque psoriasis virtually all progresses to MF
retiform parapsoriasis or parakeratosis variegate or parapsoriasis lichenoides
42
Treatment of lymphocytoma cutis
should resolve | topical steroids
43
Clinical features of PLEVA
appears in crops, polymorphic. oedematous pink papule that undergoes central vesiculation and haemorrhagic necrosis. Face usually spared. May have malaise/arthralgia. May heal with scars. Lasts 18/12
44
Tx of sezary
ECP, IFN alpha, CHOP or CHOP like | PUVA, topical steroids
45
In MF - usually T cell antigen presentation
CD4+ CD45RO+ | Loss of T cell surface antigens eg CD2, CD5, and/or CD7
46
Where is extranasal NK/T cell lymphoma found and association?
asia, central America and south America. | EBV +ve
47
Therapy of stage IA -IIA
``` Topical steroids UVB/PUVA topical nitrogen mustard bexarotene local radiation combinations of the above acitretin low dose MTX IFN alpha ```
48
5 year survival of LyP
100%
49
Types of aggressive CTCL
sezary cutaneous peripheral t cell lymphoma (NOS)- (cutaneous aggressive CD8 t cell lymphoma and cutaneous gamma/delta T cell lymphoma) Cutaneous NK/T cell lymphoma, nasal type
50
Clinical features of PLC
firm, lichenoid papule 3-10mm in diameter. Adherent mica like scale which can be scraped off to reveal a shiny brown surface. Unusual to scar Lasts 18/12
51
Prognosis of MF with large cell transformation if no risk factors, otherwise?
65% | otherwise median survival of 24 months, overall survival 33%
52
When to suspect large cell transformation
new nodule in pre-existing patch multiple scattered papules or nodules solitary nodule in a pre-existing tumour CHANGE
53
What is APACHE
acral pseudolymphomatous angiokeratoma of children - 2-16yrs. Unilateral grouping of small, red to violet angiomatous papules
54
Clinical features of ALCL
solitary or localised nodules or tumours that often develop ulceration multifocal in 20%
55
10 year survival of primary cutaneous ALCL
85%
