Lobular breast carcinoma metastatic to the vulva : A case report and literature review

Abstract Background. Six previous reports have documented a vulvar metastasis from breast cancer; one has noted involvement of the Bartholin's gland. Case. A 53-year-old woman presented with an enlarging vulvar mass. Evaluation also identified a breast lesion. Surgical excision confirmed an invasive lobular breast carcinoma with a distant metastatic focus on the vulva. Conclusion. This is the first report in the English literature to document a vulvar metastasis from an invasive lobular carcinoma and the second to identify involvement of the Bartholin's gland. Careful gynecologic surveillance is needed in women with breast cancer.
