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.
我们描述了一名49岁女性大阴唇的交界性恶性叶状肿瘤。外阴叶状肿瘤的组织发生起源存在争议。在叶状肿瘤的上皮成分中证实了对一种新型乳腺分化抗原NY-BR-1的强免疫反应性。在外阴的乳腺样腺体中观察到类似的表达模式。这些发现提供了进一步的证据,表明外阴叶状肿瘤可能起源于大阴唇的乳腺样腺体或异位乳腺组织。
