Secondary Tumors of the Vulva: A Six-Case Retrospective Series and Narrative Review

Background

Within gynecological oncology, vulvar metastases represent an exceptionally rare clinical entity, accounting for 5% to 8% of all observed vulvar lesions. Secondary vulvar tumors usually reflect advanced metastatic disease and are associated with poor prognosis. This study describes the clinical and morphological characteristics of metastatic vulvar neoplasms and compares them narratively with previously reported cases and primary vulvar malignancies.
