    ABSTRACT: We describe a phyllodes tumor of borderline malignancy in the labium majus of a 49-year-old woman. The histogenetic origin of phyllodes tumors in the vulva is controversial. Strong immunoreactivity for NY-BR-1, a novel breast differentiation antigen, was demonstrated within the epithelial components of the phyllodes tumor. A similar expression pattern was observed in mammary-like glands of the vulva. These findings provide further evidence that phyllodes tumors of the vulva might derive from mammary-like glands in the labium majus or from ectopic breast tissue.

    ABSTRACT: Mammary-type fibroepithelial neoplasms of the vulva are rare lesions of uncertain histogenesis. Origin from ectopic breast tissue and from anogenital glandular tissue that shares similar histologic homology with breast tissue has been postulated. We report the case of a 45-year-old woman who presented with a vulvar mass of several years duration. Excision of the lesion and subsequent histologic examination showed a mammary-type fibroadenoma with apocrine change. No ectopic breast tissue was identified outside the lesion. The theories of histogenesis of these neoplasms and additional cases of mammary-type lesions of the vulva reported in the medical literature are reviewed.

    ABSTRACT: Phyllodes tumors of the breast are rare breast tumors that resemble fibroadenoma. They are composed of two types of tissues: stromal and glandular tissues. Unlike fibroadenoma, they are commonly found in the third decade of life and they tend to grow more rapidly. Depending on the relative components of the cells and mitotic activity, they are classified into benign, borderline, and malignant. They are usually present as a lump in the breast. Phyllodes tumors are usually managed by wide excision. The excision should be wide enough to ensure a tumor-free margin. Recurrence rate is very high and most recurrences are usually local. Metastasis to the vulva has not been reported.
