The light and electron microscopic features of two mixed tumors of the skin of the salivary gland type demonstrate eccrine differentiation of the epithelial component. The tumors were made up of tuboalveolar spaces lined by an eccrine duct type of epithelium with luminal cells showing numerous microvilli. The mesenchymal elements were fibroblasts and chondrocytes embedded in a mucous and chondroid matrix. Groups of undifferentiated cells without eccrine differentiation but with ultrastructural features suggestive of epithelial origin were seen among the mesenchymal and epithelial elements of the tumor.
两例涎腺型皮肤混合瘤的光镜和电镜特征显示上皮成分有小汗腺分化。肿瘤由小管状腺泡间隙构成，内衬小汗腺导管样上皮，管腔细胞有大量微绒毛。间充质成分是成纤维细胞和软骨细胞，包埋于黏液样和软骨样基质中。在肿瘤的间充质和上皮成分中可见未分化细胞群，无小汗腺分化，但超微结构特征提示来源于上皮。
