Vulvar endometriosis presenting as a periurethral mass: a rare case report and a brief literature review

Year: 2026

Type: article

Abstract: Introduction: Endometriosis is a condition characterized by the presence of endometrial-like tissue outside its normal uterine location. While the pelvic cavity is the most common site of involvement, endometriosis can also affect other areas, with vulvar endometriosis being rare. Presentation of case: This case report describes a 44-year-old woman with a history of unilateral swelling of the upper part of the labia majora, accompanied by deviation of the urethral meatus, which began 5 years earlier following a spontaneous vaginal delivery. The lesion was excised completely, and based on pathological findings, vulvar endometriosis was diagnosed. Discussion: The unusual location and atypical appearance of the lesion set this case apart from previously reported cases of vulvar endometriosis. Reporting this case may assist clinicians in recognizing similar presentations and reducing the likelihood of misdiagnosis. Conclusion: Vulvar endometriosis is a rare entity with heterogeneous clinical manifestations. Accurate diagnosis relies on meticulous evaluation and histopathological confirmation. Treatment is by complete surgical excision, offering symptomatic relief and minimizing the risk of recurrence.
