How to describe lesions

General observation

1) site

2) number of lesions

3) pattern of distribution and configuration

 

Describe individual lesions

1) size

2)  shape

3) colour

4) primary morphology

5) secondary morphology 

6) margin

2

Palpate lesions and feel for:

1) surface 2) consistency 3) mobility 4) tenderness 5) temperature

3

comedone

What is this and what is the cause/ your managment / complications 

Q image thumb

complication of atopic eczema

cause: Herpes simplex virus

Managment: antivirals e.g. aciclovir 

AB for bacterial secondary infection 

Complications: herpes hepatitis, encephalitis, disseminated intravasuclar coagulation (DIC) and rarely death

managment

complications 

Q image thumb

Erythroderma

skin appears inflamed, oedematous and scaly

wide spread erythema 

systemically unwell with lymphadenoapthy and malaise

treat underlying cause (Eczema, psorisasis, lymphoma, drugs, idiopathic)

emollients and wet wraps to maintain mositure

topical steroids may relieve inflammation

complications: secondary infection, fluid loss, electrolyte imbalance, hypothermia, high output caridac failure and capillary leak syndrome

What is this 

Q image thumb

Squamous cell carcinoma

ill defined nodule which may ulcerate

can be keratotic e.g. scaly and crusty 

25

What is this 

Q image thumb

bilateral erythmatous dry scaly patches on antecubital fossas - felxural surfaces 

can see signs of excoriations which suggests chronic scratching/ rubbing 

26

What is this 

Q image thumb

wide spread, well demarcated discrete erythmatous scaly plaques 

may be itchy, burning or painful

common on extensor surfaces and scalp 

27

What is this

pearly traslucnet nodule

telangiesctasia
