Introduction

Vulvar lichen sclerosus (VLS) is a chronic inflammatory dermatosis of unclear etiology, most often affecting postmenopausal women. It presents with itching, burning, pain, and progressive vulvar scarring and atrophy, leading to sexual dysfunction and increased risk of neoplastic transformation. High-potency corticosteroids are the standard first-line treatment, but many patients experience inadequate response or intolerance, resulting in recurrence. In such cases, 5-aminolevulinate (ALA) photodynamic therapy (PDT) may offer an alternative. The aim of this systematic review was to evaluate the effectiveness and safety of PDT in patients with VLS.

Methods

Searches of PubMed, Scopus, and Web of Science identified 238 papers, of which 13 met the inclusion criteria, comprising 441 women with VLS. Among these, one was a randomized controlled trial, one a non-randomized comparative study, seven were single-arm trials, and four were retrospective analyses.

Results

The collective evidence showed that PDT, particularly using 5-ALA as a photosensitizer, improved clinical symptoms such as pain and itching, skin histology, patients’ quality of life as measured with the Dermatology Life Quality Index, and sexual functioning as measured with the Female Sexual Function Index. Adverse events were mainly procedure-related and resolved spontaneously within a few days.

Discussion

PDT appears to be a promising therapeutic option for VLS, particularly in patients with refractory disease unresponsive to conventional treatments. However, evidence for ALA-PDT remains limited, as current studies are small, use variable protocols, and involve heterogeneous populations. Further research is needed to address these gaps.

Conclusion

Available studies indicate that ALA-PDT is a safe, well-tolerated, and effective option for VLS, improving both symptoms and clinical signs, especially in refractory cases. Emerging evidence, including comparative and quality-of-life studies, supports its potential role in management, though large prospective trials are needed to refine protocols and establish guideline recommendations.
