BCC features
slow growing locally invasive malignant tumor of epidermal keratinocytes
most common malignant skin tumor
BCC RFs
UV exposure ^ age M gender frequent sunburns skin type I genetic predisposition immunosuppression PMx of skin cancer
BCC presentation
nodular superficial sclerosing keratotic cystic pigmented \+/- surface telangiectasia pealy rolled edge \+/- necrotic / ulcerated centre
BCC management
2WW referral
surgical excision
BCC complications
local tissue invasion / destruction
SCC features
locally invasive malignant tumor of epithelial keratinocytes and its appendages and has the ability to metastasise
SCC RFs
UV exposure
immunosuppression
pre-malignant conditions eg. actinic keratosis
chronic inflammation (leg ulcers / wound scars)
genetic predisposition
SCC presentation
keratotic
ill defined nodule
+/- ulceration
SCC management
2WW ref
surgical excision
radiotherapy (for large, non-resectable tumors)
Melanoma features
invasive malignant tumor of epithelial melanocytes which has the potential to metastasise
Melanoma RFs
UV exposure freq sunburn skin type I Fx in first degree Hx of melanoma > 100 moles / atypical naevus syndromes
Melanoma presentation
Asymmetrical Border irregular Color irregular (dark / non-uniform) Diameter > 6mm Evolution of lesion (change in colour, shape, border etc.) Symptoms inc. bleeding / itching more common on legs in W, trunk on M
Melanoma management
2WW + biopsy
wide local excision +/- radiotherapy
chemotherapy for metastases
Melanoma prognosis
90% survival rate in 10 years in England and Wales
Eczema presentation
common in children
itchy papules and weepy exudate formation
dry scaly
erythematous / grey / brown
+/- hypopigmentation / hyperpigmentation
+/- lichenification
+/- nail changes (pitting / ridges)
