BACKGROUND: Porokeratosis is a group of disorders characterized by aberrant skin keratinization secondary to genetic alterations in the mevalonate pathway, which participates in cholesterol synthesis. While a rare disorder, malignant transformation to squamous cell carcinoma is seen in up to 11% of cases. Recently, topical cholesterol and topical statin therapy have been suggested as a pathogenesis-directed treatment for porokeratosis.
METHODS: A PubMed/MEDLINE and Embase literature search was performed using the search terms: "porokeratosis" AND "cholesterol" OR "lovastatin" OR "simvastatin" OR "atorvastatin" OR "fluvastatin" OR "pitavastatin" OR "pravastatin" OR "rosuvastatin" OR "statin." Peer-reviewed clinical trials, case series, and case reports of all porokeratosis subtypes were included.
RESULTS: Eleven articles were included in the systematic review and 9 articles in the meta-analysis. The systematic review consisted of an aggregate of 33 patients, most of whom (n=31, 93.9%) applied the treatment twice daily for an average of 9.4 weeks (median=8 weeks), with 93.9% (n=31) experiencing improvement or resolution of porokeratosis. Sixteen patients (48.5%) used lovastatin and 16 (48.5%) used simvastatin with concurrent cholesterol therapy. Mild adverse events including erythema and contact dermatitis were experienced by 12.1% of patients. Our meta-analysis yielded a random effects model supporting a robust reduction in porokeratosis severity (OR = .076, 95% CI [0.022, 0.262]).
CONCLUSION: This underpowered meta-analysis provides limited, preliminary evidence supporting the efficacy of topical cholesterol/statin therapy. Overall, quality studies and aggregated sample size are limited; future large clinical trials are needed to further elucidate the role of topical cholesterol/statin therapy in the treatment of porokeratosis.
