Three black women were found to have granular-cell tumors on the vulva; in one, there were several additionally in other cutaneous sites. Although this benign neoplasm is uncommon on the vulva, it should be considered in the differential diagnosis of nodular lesions on the vulva. Granular-cell tumors in multiplicity occur frequently and are not a sign of metastatic disease. This lesion has predilection for blacks. Pseudocarcinomatous hyperplasia occurs typically in overlying squamous epithelium and may be misinterpreted as squamous-cell carcinoma.
三名黑人女性被发现外阴有颗粒细胞瘤；其中一人在其他皮肤部位还有几处。尽管这种良性肿瘤在外阴并不常见，但在外阴结节性病变的鉴别诊断中应予以考虑。多发性颗粒细胞瘤很常见，并非转移性疾病的迹象。这种病变在黑人中更为常见。假癌性增生通常发生在上覆的鳞状上皮中，可能会被误诊为鳞状细胞癌。
