This article reports a case of intractable Queyrat erythroplasia involving the urethral meatus. The study suggests that 5-aminolaevulinic acid photodynamic therapy is effective and safe in the treatment of Queyrat erythroplasia, providing a new choice for patients with poor therapeutic effect.
Queyrat erythroplasia is an intraepidermal squamous cell carcinoma localized on the glans penis or the inner side of the foreskin. It accounts for about 10% of all penile malignancies and up to 33% cases may lead to invasive squamous cell carcinoma and the intraurethral erythroplasia of Queyrat is relatively rare. Treatment of Queyrat erythroplasia present a challenge especially if the proximal urethra is involved.Here, we report a case of intractable Queyrat erythroplasia involving the urethral meatus. This case suggested that 5-aminolaevulinic acid photodynamic therapy is effective and safe in the treatment of Queyrat erythroplasia, which provides a new choice for the patients with Queyrat erythroplasia with poor therapeutic effect.
