Bowen's disease is a squamous cell carcinoma in situ and has the potential to progress to a squamous cell carcinoma. The authors treated two female patients (a 39-year-old and a 41-year-old) with Bowen's disease in the vulva area using topical photodynamic therapy (PDT), involving the use of 5-aminolaevulinic acid and a light-emitting diode device. The light was administered at an intensity of 80 mW/cm(2) for a dose of 120 J/cm(2) biweekly for 6 cycles. The 39-year-old patient showed excellent clinical improvement, but the other patient achieved only a partial response. Even though one patient underwent a total excision 1 year later due to recurrence, both patients were satisfied with the cosmetic outcomes of this therapy and the partial improvement over time. The common side effect of PDT was a stinging sensation. PDT provides a relatively effective and useful alternative treatment for Bowen's disease in the vulva area.

Bowen's disease (BD) is an intraepithelial squamous cell carcinoma (SCC) that commonly affects older individuals, with the vulva being a prevalent site in women. Lesions within the vagina pose a particular challenge for surgical treatment, often compromising both functional integrity and cosmesis. Photodynamic therapy (PDT) is an emerging, safe, and non-invasive technique utilizing a photosensitizer and a specific light source, widely applied in the treatment of malignancies and skin diseases.

Background: Photodynamic therapy (PDT) is a widely-used non-surgical treatment for non-melanoma skin cancers, including basal cell carcinoma (BCC), actinic keratoses (AK), and Bowen's disease (BD). PDT has high success rates, but various factors, can influence treatment response. This study investigates the clinical, histological, and molecular factors that affect the efficacy of methyl aminolevulinate PDT (MAL-PDT) for BCC and BD.

Background: Discrete choice experiments (DCEs) are increasingly used to understand and quantify patient preferences for a variety of treatments, services or screening in order to analyse the choices patients make when faced with different alternatives. The aim of this DCE was to examine patient preferences for the treatment of Bowen's disease.
Methods: A DCE was conducted alongside a randomised controlled non-inferiority trial comparing the effectiveness of surgical excision, MAL-PDT, and 5-fluorouracil cream as treatments for Bowen's disease.
Article Synopsis
- The article presents a clinical case of a young patient with HPV-associated penile intraepithelial neoplasia (PIN), specifically the erythematous form of bowenoid papulosis.
- It highlights the issues of delayed diagnosis due to improper diagnostic approaches and a lack of awareness among doctors about cancer-related diseases.
- The piece emphasizes the significance of early detection in preventing progression to more severe conditions like squamous cell penile carcinoma, detailing the different subtypes of PIN and their varying risks of leading to cancer.
