This report illustrates an extradigital fibromatosis located in the right upper arm. The clinical, light-, and electron-microscopic features were identical to those found in the recurrent digital fibromatosis of childhood. As is typical for infantile digital fibromatosis, this reported lesion recurred once. Light microscopy showed eosinophilic, perinuclear inclusions which by electron microscopy were nonmembrane-bound, compact fibrillary structures. Whereas major reviews state that infantile digital fibromas occur exclusively on the digits, this unique case describes the rare occurrence outside the digit.
本报告展示了一例位于右上臂的指外纤维瘤病。其临床、光镜和电镜特征与儿童复发性指纤维瘤病所见相同。正如婴儿指纤维瘤病的典型情况，该报告的病变复发过一次。光镜显示嗜酸性核周包涵体，电镜下为无膜包绕的致密纤维状结构。尽管主要综述称婴儿指纤维瘤仅发生于手指，但这一独特病例描述了在手指以外部位的罕见发生情况。
