Autosomal dominant
What management would you recommend?
Careful sun protection may reduce the number of lesions. No curative treatment has been found, but the lesions may occasionally involute spontaneously. A variety of topical therapies may reduce the unsightliness and dryness including emollients, alpha hydroxy acids, retinoids, calcipotriol and fluorouracil. Cryotherapy can eradicate individual plaques.
What complication may arise?
Squamous cell carcinoma may arise within the plaques. Patients with disseminated superficial actinic porokeratosis may also be prone to basal cell carcinoma.
