Abdominal skin

3

Scalp

4

What is wrong with this?

lmao nothing :)

5

What disease is seen under histology here?

Psoriasis 

6

Which layer of the skin is this?

Prickle cell layer 

Look for the desmosomes attaching the larger polyhedral cells 

7

What pathology is occuring in this picture?

Its a viral wart - HPV infection of keratinocytes 

8

What kind of cell is the arrow pointing to?

Melanocyte 

9

what pathology is seen here?

Angioma 

10

What is the circular shaped cells seen here?

Pacinian corpurscles

11

What kind of gland is seen here?

A sebacaeous gland 

12

What kind of gland is this?

Apocrine gland 

13

What kind of gland is this?

An eccrine gland 

14

When might you see this immunoflurescence?

Bullous pemhigoid - IgG along the DEJ 

15

What word would you describe to explain the basic pathology here?

Papillomatosis 

16

What two abnormalities is there present within the epidermis?

Spongiosis and inflammatory cell infiltrates 

17

What is the underlying pathology here?

Scabies 

18

What pathology is seen here?

Lichen planus 

Can see: 

•Irregular sawtooth acanthosis

•Hypergranulosis and orthohyperkeratosis

•Band-like upper dermal infiltrate of lymphocytes

•Basal damage with formation of cytoid bodies

19

End result seen in pemphigus vulgaris?

acantholysis 

20

Where is IgG deposited in pemphigus?

Intradermal - still some hemidesmosomal attachments 

21

What does IgG deposition look like in pemphigoid?

Linear 

22

What pathology is going on here?

iDermatitis herpetiformis - papillary dermal abcesses seen (the thing that looks like a weird white flavoured loollipop)

 

Will get granular deposition of IgA

23

Whats the happs here?

Rosacea 

Can see the follicular demodex mite in

And apparently perifollicular granulomas  

24

Cause of this immunoflurensence 

Seen in dermatitis herpetiformis 

Granular deposition of IgA

25

Are there inflammatory infliltrates in all types of dermatitis? 

No, inflammatory infiltrates are specific to eczema. 

However, there is spongiosis found within all types of dermatitis. 

26

What type of naevus is this and what age might it occur? 

It is a junctional naevus - can see the cluster of melanocytes at the DEJ ready to move down 

Present in childhood 

27

What type of naevus is this and when might it occur? 

soz cant find pic lol xx melanocytes present below the DEJ 

This is intradermal naevus which occurs in adulthood

All the melanocytes which give it pigment are now resting in the dermis - ie all the little dark dots 

28

Dysplastic naevus affects what layer of skin?

Dermis - does not affect epidermis like melanoma 

29

What type of naevus is this?

This is a dysplastic naevus - there is apparently cellular atypia, can see some inflammatory cells and the clumps of melanocytes are localised to the dermis 

30

What type of naevus is this? 

This is a spitz naevus 

Consists of spindle and epthoidal cells 

Benign juvenille 

31

What type of naevus is this? 

Blue naevus 

Can see rich dendritic spindle cells, it is entirely dermal 

32

What type of cancer is this? 

This is a superficial spreading melanoma commonly found on the trunk and legs 

 

It is purely epidermal 

33

Which type of melanoma is this?

This is a dermally invasive form of melanoma - VGP 

34

Which type of melanoma is this?

This is a nodular melanoma, it is believed to be the most aggressive
