Extra-adrenal myelolipomas (EAMLs) are extremely rare soft tissue tumours that constitute <15% of all myelolipomas. We present a 70-year-old patient with a midline swelling of the anterior abdominal wall. It was clinically diagnosed as an incisional hernia, though the computerized scan indicated an internal hernia. During laparoscopy a soft tissue tumour of the abdominal wall was identified and excised. Pathology confirmed an extra-adrenal myelolipoma of the anterior abdominal wall through the presence of adipocytes and trilineage haematopoetic cell lines. EAMLs are rare mesenchymal soft tissue tumours with less than a hundred cases reported in the English literature. Pathological diagnosis shows the presence of mature adipocytes as well as myeloid and erythroid cell lines. This is the first case report of an EAML of the anterior abdominal wall. This case report is made even more rare as it is present in a male patient.
肾上腺外髓脂肪瘤（EAML）是极其罕见的软组织肿瘤，占所有髓脂肪瘤的比例不到15%。我们报告一名70岁患者，其前腹壁出现中线肿胀。临床诊断为切口疝，尽管计算机扫描显示为内疝。在腹腔镜检查期间，发现并切除了腹壁的一个软组织肿瘤。病理检查通过脂肪细胞和三系造血细胞系的存在证实为前腹壁肾上腺外髓脂肪瘤。EAML是罕见的间叶性软组织肿瘤，英文文献报道的病例不到100例。病理诊断显示存在成熟脂肪细胞以及髓系和红系细胞系。这是前腹壁EAML的首例病例报告。该病例报告更为罕见的是，患者为男性。
