Premalignant lesions
• Actinic keratosis i • A typical lesion is an irregularly shaped, flat, slightly erythematous papule with indistinct borders and an overlying hard keratotic scale or horn.
Actinic keratosis
is a premalignant
form of squamous cell carcinoma
affecting nearly all of the older
Caucasian population.
A typical lesion
is an irregularly
shaped, flat, slightly erythematous
papule with indistinct borders and an
overlying hard keratotic scale or horn.
• Treatment premalignant lesion
includes cryosurgery,
fluorouracil, surgical removal, tretinoin
and chemical peeling agents.
Malignant lesions • Frequently related to sun exposure— prevention: use sunscreen and avoid sun exposure • Prevention of all types of skin cancer involves protection from excessive sun exposure
Basal cell carcinoma (BCC)
Squamous cell carcinoma (SCC)
Basal cell carcinoma (BCC)
Most common type and most successfully treated
because tumours remain localised
Squamous cell carcinoma (SCC)
Border of an SCC lesion is wider, deeper and more
inflammatory than a BCC lesion
Malignant lesions causes and prevention
• Frequently related to sun exposure— prevention: use sunscreen and avoid sun exposure • Prevention of all types of skin cancer involves protection from excessive sun exposure
Nursing Management / Education Malignant lesions
• High cure rate (over 99%) with early treatment
• The earlier the treatment is initiated, the less invasive it
will be
treatment Malignant lesions
Treatment includes: • Excision • Cryosurgery • Radiation therapy • Electrodessication and curettage
