作者报告一例3岁患儿,主诉外伤后鼻畸形,鼻侧切开切除肿瘤。病理报告为黄色肉芽肿(Xan-thogranuloma)。类似病例过去在日本仅有一例报告。黄色肉芽肿属纤维性组织细胞瘤,病理特点:含成纤维细胞、含脂肪的组织细胞及Touton巨细胞、类组织细胞。常归入良性肿瘤,但有时呈恶性经过。Ozzello对组织细胞进行培养,证明可转化为成纤维细胞。Stout等将以组织细胞为主的肿瘤样增殖归总为纤维性组织细胞 The authors report a case of a 3-year-old patient who complained of a nasal deformity after trauma and had a nasal incision to remove the tumor. The pathology report was Xan- thogranuloma. Similar cases have only been reported in Japan in the past. Yellow granuloma is a fibrous histiocytoma, pathological features: containing fibroblasts, fat-containing tissue cells and Touton giant cells, tissue-like cells. Often classified as benign, but sometimes malignant. Ozzello cultured tissue cells and proved to be transformed into fibroblasts. Stout et al. (1994) categorize cell-based tumor-like proliferation as fibrous tissue cells.
