A case of fibrous hamartoma of infancy in the left axilla of an 18-month-old boy, is reported with some discussion (citations of references). The tumor was situated in the subcutaneous fatty tissue, and its border was unclear. It was removed easily and found to measure 2.5 X 1.5 X 1.5 cm. Histologically, in addition to the three main components, i.e., trabeculae of fibrous tissue, immature mesenchymal cells with a mucoid matrix and interspersed mature fat, a capillary vasoformative proliferation, peripheral nerve fibers and lymph follicle-like structures mingling with and transforming into one another were noted throughout the tumor. On the basis of these findings, immature mesenchymal cells were considered as having very important roles with regard to the histogenesis of fibrous hamartoma of infancy.
报告了一名18个月大男孩左腋窝婴儿纤维性错构瘤的病例，并进行了一些讨论（参考文献引用）。肿瘤位于皮下脂肪组织中，边界不清。肿瘤很容易被切除，大小为2.5×1.5×1.5厘米。组织学上，除了三个主要成分，即纤维组织小梁、具有黏液样基质的未成熟间充质细胞和散在的成熟脂肪外，在整个肿瘤中还发现有毛细血管形成性增生、周围神经纤维以及相互交织并相互转化的淋巴滤泡样结构。基于这些发现，未成熟间充质细胞被认为在婴儿纤维性错构瘤的组织发生中具有非常重要的作用。
