BACKGROUND
Lipoid proteinosis (LP), also known as Urbach-Wiethe disease, is a rare autosomal recessive genodermatosis, caused by mutations in the ECM1 gene. This results in the deposition of periodic acid-Schiff (PAS)-positive, hyaline-like material on the skin, mucosae and internal organs.
OBJECTIVES
To present a case report of LP and a systematic review to synthesize the scientific literature on the management of this uncommon and frequently missed diagnosis.
METHODS
We present a case report of a 48-year-old man with LP who exhibited significant improvement after oral acitretin therapy. To address the lack of large case-control studies on LP treatment, we performed a systematic review of the literature following the PRISMA 2020 criteria. The search was conducted in PubMed, Web of Science, Cochrane and Scopus databases from inception until June 2023. To assess the methodological quality of case reports and case series, we used the Joanna Briggs Collaboration critical appraisal tool.
RESULTS
We included 25 studies that met eligibility criteria. Data from 44 patients with a histopathologically confirmed diagnosis were analysed. Treatment ranged from systemic therapies (acitretin, etretinate, dimethyl sulfoxide, corticosteroids, penicillamine) to surgical or laser procedures. Regarding methodological quality, the main discrepancies arose in the reporting of participant characteristics and treatment interventions.
CONCLUSIONS
Low-dose oral acitretin could have potential in managing LP, exhibiting fewer side-effects compared with other therapeutic agents. Further research is needed to establish more comprehensive and evidence-based treatment guidelines.

Review
PURPOSE
We evaluate the efficacy and safety profiles of currently available conservative management options for penile and urethral lichen sclerosus.
MATERIALS AND METHODS
A systematic review of existing literature on lichen sclerosus was conducted utilizing the PubMed, Embase, and Web of Science databases. References were assessed for relevance to nonsurgical management of male genital lichen sclerosus by title and abstract by 3 independent reviewers, then reviewed in full and in duplicate by 5 independent reviewers.
RESULTS
Seventeen studies describing conservative management of histologically confirmed penile and urethral lichen sclerosus in male patients were included in the final review. We present available evidence supporting the use of 4 major treatment modalities represented in the existing literature: topical corticosteroids, tacrolimus, platelet-rich plasma, and CO laser. We also briefly discuss the limited studies on the use of oral acitretin and polydeoxyribonucleotide injections. Outcomes assessed include symptoms, clinical appearance, quality of life, sexual satisfaction, adverse effects, and long-term efficacy of treatment.
CONCLUSIONS
Topical corticosteroids remain the mainstay of conservative management of penile and urethral lichen sclerosus, with current literature supporting the use of other therapies such as tacrolimus and platelet-rich plasma as alternatives or adjuvant treatments when escalation of treatment is necessary. Future research should further explore the efficacy and safety of newer therapies through additional controlled clinical trials in the targeted population.

Psoriasis vulgaris (PV) is a longstanding, inflammatory, immune-responsive skin condition. Chinese herbal medicine injections (CHMIs) have been utilized for treating PV in Asian countries. This study aims to conduct a thorough systematic review and meta-analysis to comprehensively appraise the efficacy of CHMIs in treating PV. Seven databases were searched for randomized controlled trials that evaluated the effect of CHMIs in treating PV, ranging from 2004 to June 2022. The meta-analysis was undertaken based on outcome measures, treatment options, and treatment durations using Review Manager 5.4. The primary outcome measure of this study was a 60% or higher reduction in the Psoriasis Area and Severity Index score (PASI 60). A descriptive analysis was performed for the assessment of adverse events. This systematic review incorporated 33 studies, comprising 3,059 participants. The main findings indicated significant differences based on the PASI 60 (RR = 1.30, 95% CI: 1.24 to 1.37, Z = 10.72, < 0.00001), PASI 30 (RR = 1.25, 95% CI: 1.13 to 1.38, Z = 4.48, < 0.00001), and PASI 20 (RR = 1.28, 95% CI: 1.13 to 1.45, Z = 3.82, = 0.0001) outcome measures. Evaluating the treatment options, CHMIs in combination with monotherapies like narrowband ultraviolet B (NB-UVB) and the acitretin capsule (AC) showed a greater reduction in PASI 60 (RR = 1.33, 95% CI: 1.25 to 1.43, Z = 8.32, < 0.00001). In terms of treatment duration, no significant difference was observed when the duration extended beyond 56 days. Furthermore, the results suggested that CHMIs might reduce the incidence of adverse events in the treatment of PV. This systematic review revealed preliminary clinical evidence supporting the use of CHMIs for treating PV, considering outcome measures, treatment options, and treatment durations. However, due to the low methodological quality and limited sample size of the included studies, there is an urgent need for high-quality, multi-center and larger-scale studies of CHMIs for PV to provide robust evidence for their clinical application. : [https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=326531], identifier [CRD42022326531].
