Published: January 2025

Introduction And Importance: Cervical cancer is highly correlated with high-risk human papillomavirus (HPV) infection, accounting for approximately 70 % of cases. However, false-negative HPV test results can occur, complicating early detection.

Case Presentation: We introduce a rare case of cervical cancer with lung metastasis followed by vulvar metastasis. Notably, the HPV test was negative at diagnosis but became positive upon detection of vulvar metastasis.

Clinical Discussion: We discuss the pathways of vulvar metastasis in cervical cancer and potential causes of false-negative HPV tests. A search for cases of vulvar metastasis of cervical cancer in Medline and Embase between 2004 and 2024 was performed and a literature review was conducted.

Conclusion: The occurrence of vulvar metastasis indicates the terminal manifestation of the tumor and the survival period is short. Active radiotherapy, chemotherapy, immunotherapy and other multiple treatments may increase the overall survival time of patients.

Both women and men are now confronted with the grave threat of cancers caused by the human papillomavirus (HPV). It is estimated that 80% of women may encounter HPV over their lives. In the preponderance of cases involving anal, head and neck, oral, oropharyngeal, penile, vaginal, vulvar, and cervical malignancies, high-risk HPV (HR-HPV) is the causative agent.

Myoepithelioma-like tumor of the vulvar region (MELTVR) is a rare mesenchymal tumor that typically arises in the female vulva. Here, we report a case of a 48-year-old woman who presented with a 2-year history of subcutaneous mass in the vulvar region. As the mass rapidly increased in the last 2 months, personal slight swelling pain appeared.

Vulvar adenocarcinoma of the intestinal type (VAIt) is a rare subtype of primary vulvar carcinoma, with ∼30 cases documented in the English literature. This study presents 2 new cases of HPV-independent VAIt with lymph node metastasis and discusses their clinical presentation, histopathologic features, and whole exome sequencing (WES) analysis. Both cases exhibited histologic features consistent with VAIt, including tubular, papillary, and mucinous carcinoma components.

Vulvar cancer is one of the rarest gynecological malignancies. The development of this condition can be associated with either dysplasia linked to human papillomavirus (HPV), primarily affecting younger women, or vulvar dermatoses such as lichen sclerosus, which predominantly affect older women. Over the last decade, the incidence of vulvar cancer has risen by 0.
