Aneurysmal benign fibrous histiocytoma is an uncommon pathologic variant of dermatofibroma. In addition to the features of a typical dermatofibroma, it has large cleft-like or cavernous blood-filled spaces with numerous hemosiderin pigments. It should be differentiated from angiomatoid malignant fibrous histiocytoma, malignant melanoma, and vascular tumors such as Kaposi's sarcoma and angiosarcoma. Atrophic dermatofibroma is also a rare variant of dermatofibroma, and the combination of aneurysmal and atrophic features is rarer still. We report a case of aneurysmal benign fibrous histiocytoma with atrophic features in a 27-year-old male who had a grayish-brown atrophic patchy lesion on his back for 2 years.
动脉瘤样良性纤维组织细胞瘤是皮肤纤维瘤一种罕见的病理变体。除具有典型皮肤纤维瘤的特征外，它还有大的裂隙样或充满血液的海绵状间隙以及大量含铁血黄素色素。它应与血管样恶性纤维组织细胞瘤、恶性黑色素瘤以及诸如卡波西肉瘤和血管肉瘤等血管肿瘤相鉴别。萎缩性皮肤纤维瘤也是皮肤纤维瘤的一种罕见变体，而动脉瘤样和萎缩性特征并存则更为罕见。我们报告一例27岁男性的具有萎缩性特征的动脉瘤样良性纤维组织细胞瘤，该患者背部有一灰棕色萎缩性斑片状损害已2年。
