Skin surgery • Send all specimens for pathology • Accurate information on pathology form, eg site, clinical description • One specimen, one pot
Distinguish vascular lesions from pigmented ones • Distinguish melanocytic lesions from seb warts • Adjunct to diagnosis • If in doubt refer
Management of pre- malignant non pigmented lesions • Diagnostic biopsy • Curettage • Efudix • PDT • excision
~ 100 000 non melanoma skin cancers / year • 80% NMSC occur > 60 years of age • 95 % survival in NMSC overall • ~ 10 000 melanomas / year • Incidence doubling every 10 years
SCC - prognosis • Lip • Ear • Immunocompromised pt • Higher recurrence rates
Treatments for NMSC • Excision • Radiotherapy • Mohs surgery
Mohs surgery • Microscpoically controlled • Margins examined • Precise removal of tumour • Used in cosmetically important areas • Tissue sparing
Malignant melanoma • Commonest cancer in 15 -34 age group • Commoner than cervical cancer in women • Average 20 years loss of life for each death • Positive correlation with affluence
