Solar keratoses
Solar keratoses (actinic keratoses) are scaly areas of the skin resulting from excessive cumulative sun exposure i.e. sun exposure during a lifetime.
If left alone, they may progress to a skin cancer called Squamous cell carcinoma (SCC).
Options of treatment of solar keratoses include:
-
Aldara cream
-
Efudix cream
-
Photodynamic therapy.
Bowen's disease
Bowens disease is a squamous cell carcinoma in situ (confined to the epidermis) and progresses to an invasive squamous cell carcinoma in 3-5% of cases. Diagnosis is confirmed on biopsy of the involved area of skin.
