1

A slow-growing, locally invasive malignant tumour of the epidermal keratinocytes normally in older individuals, only rarely metastasises

Basal Cell Carcinoma

2

BCC types

Nodular (most common)
Superficial (plaque-like)
Cystic
Keratotic
Pigmented

3

A skin-coloured papule or nodule with surface telangiectasia, and a pearly rolled edge; the lesion may have a necrotic or ulcerated centre

Basal Cell Carcinoma (AKA 'rodent ulcer' if ulcerated centre)

4

A locally invasive malignant tumour of the epidermal keratinocytes or its appendages, which has the potential to metastasise

Squamous Cell Carcinoma

5

Keratotic (e.g. scaly, crusty), ill-defined nodule which may ulcerate. Raised, everted edges

Squamous Cell Carcinoma

6

An invasive malignant tumour of the epidermal melanocytes, which has the potential to metastasise

Malignant Melanoma

7

ABCDE Symptoms

Of malignant melanoma:

Asymmetrical shape*
Border irregularity
Colour irregularity*
Diameter > 6mm
Evolution of lesion (e.g. change in size and/or shape)*
Symptoms (e.g. bleeding, itching)

8

Flat, irregular, pigmented lesion. It occurs most often in younger females on the leg. The tumour is macular with an irregular edge, and may itch or bleed.

Superficial spreading malignant melanoma

9

A thickened, pigmented, irregular lesion (sometimes growing on the edge of the previous one). Common in elderly people on the face, and sun-exposed skin.

Lentigo maligna melanoma

10

Thick, protruding, smooth, sharply defined lesions that grow in a vertical direction and may bleed and ulcerate. They are the most aggressive of all melanomas. Common on the trunk.

Nodular melanoma.

May also not be pigmented (amelanotic) - this is associated with a worse prognosis.

11

Expanding pigmented lesions on the palms, soles and nail beds. This is the most common presentation in African-Caribbean & elderly people.

Acral lentiginous melanoma
