Eight cases of fibrous hamartomas of infancy are presented. Actin positivity and desmin negativity in collagen forming spindle-shaped cells and electron microscopical findings point to the myofibroblastic nature of this entity. "Dark cells" which spread regularly in all but one of our tumors were immunohistochemically determined to be a mixture of B and T cell lymphocytes. Their selective location and possible role are discussed.
本文报告了8例婴儿纤维性错构瘤。形成胶原的梭形细胞中肌动蛋白阳性、结蛋白阴性以及电子显微镜检查结果表明该病变具有肌成纤维细胞性质。除1例肿瘤外，在我们所有肿瘤中均有规律分布的“暗细胞”经免疫组织化学测定为B淋巴细胞和T淋巴细胞的混合物。对它们的选择性定位及可能的作用进行了讨论。
