This paper presents light and electron microscopic findings in a case of fibrous hamartoma of infancy. Histological examination revealed different tissue components: irregular trabecular collagen fibers among mature adipose tissue, and mesenchymal cells at the border of fibrocollagenous trabeculae as well as around blood vessels. Ultrastructurally most of the tumor cells represented myofibroblasts. According to the predominance of a distinct cell type, fibrous hamartoma of infancy cannot be regarded as a hamartomatous lesion but should be included in the group of juvenile fibromatoses under the term 'infantile subcutaneous myofibroblastoma'.
本文介绍了一例婴儿纤维性错构瘤的光镜和电镜检查结果。组织学检查显示不同的组织成分：成熟脂肪组织中不规则的小梁状胶原纤维，以及纤维胶原小梁边界和血管周围的间充质细胞。超微结构上，大多数肿瘤细胞为肌成纤维细胞。根据一种独特细胞类型的优势，婴儿纤维性错构瘤不应被视为错构瘤性病变，而应归入青少年纤维瘤病组，称为“婴儿皮下肌成纤维细胞瘤”。
