Medication Summary
These medications have proven the most efficacious for the treatment of hyperkeratosis lenticularis perstans (Flegel disease).
Topical cytotoxic agents
Class Summary
Inhibit cell growth and proliferation.
Fluorouracil topical (Efudex, Fluoroplex)
In clinical use since 1960s. Systemic absorption is limited to approximately 6% of applied dose and is selectively higher in abnormal skin. Interferes with pyrimidine metabolism by inhibiting thymidylate synthetase, thus inhibiting DNA synthesis.
Available as 5% (Efudex) or 1% (Fluoroplex) cream, 2% or 5% solution (both Efudex), or 1% solution (Fluoroplex).
If applied with fingers, wash hands immediately after application.
FDA-approved uses are for treatment of actinic keratosis and superficial basal cell carcinomas.
Vitamins
Class Summary
Essential for normal DNA synthesis.
Calcipotriene (Dovonex)
A synthetic vitamin D-3 derivative that possesses therapeutic properties similar to vitamin D-3, including inhibition of epidermal proliferation, induction of differentiation, and anti-inflammatory effects.
