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

Basal Cell Carcinoma


BCC types

Nodular (most common)
Superficial (plaque-like)


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)


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

Squamous Cell Carcinoma


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

Squamous Cell Carcinoma


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

Malignant Melanoma


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)


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


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


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.


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

Acral lentiginous melanoma
