Atypical fibrous histiocytoma is a distinctive variant of cutaneous fibrous histiocytoma, which is often mistaken histologically for sarcoma and which have a tendency to recur locally and a capacity to metastasize, although very rarely. We report a new case of atypical cutaneous fibrous histiocytoma in a 31-year-old man who presented with a recurrent polypoid nodule on the abdominal wall. The diagnosis was made on the basis of morphological and immunohistochemical findings. We discuss through this case and a review of the literature pathological and evolutive features and diagnostic difficulties of this entity.
非典型纤维组织细胞瘤是皮肤纤维组织细胞瘤的一种独特变体，在组织学上常被误诊为肉瘤，虽极为罕见，但有局部复发倾向且具备转移能力。我们报告一例31岁男性的非典型皮肤纤维组织细胞瘤新病例，该患者腹壁出现复发性息肉样结节。诊断基于形态学和免疫组化结果。我们通过该病例及文献复习讨论了该实体的病理及演变特征和诊断难点。
