Angiomatoid fibrous histiocytoma (AFH) is a rare, low-grade malignant soft-tissue tumor most commonly occurring in the extremities of children and young adults and has a low potential of local recurrence and metastasis. Here, we present a case of recurrent subcutaneous perianal AFH. After an initial diagnosis as a sebaceous cyst, we were able to use immunohistochemical findings to correctly identify the mass as an AFH. The patient was effectively treated after 3 surgical resections. This case emphasizes the need to correctly diagnose soft-tissue tumors using a variety of diagnostic modalities to ensure that the patient receives proper treatment.
血管样纤维组织细胞瘤（AFH）是一种罕见的低度恶性软组织肿瘤，最常见于儿童和青年成人的四肢，局部复发和转移的可能性较低。在此，我们报告一例复发性肛周皮下AFH病例。最初诊断为皮脂腺囊肿后，我们通过免疫组化结果正确地将该肿块鉴定为AFH。该患者经3次手术切除后得到有效治疗。本病例强调了需要使用多种诊断方法正确诊断软组织肿瘤，以确保患者得到恰当治疗。
