We report a rare case of dedifferentiated liposarcoma in a man. A 60-year-old male patient presented with a left mass involving the whole breast area, with no lymph node enlargement, growing during a one-year-period. Imaging studies revealed a fat-containing mixed-density mass apparently associated with the pectoralis major muscle. A core biopsy was performed that yielded a diagnosis of a well-differentiated liposarcoma. Further tests to check for metastases were ordered and no distant disease was found. Left mastectomy with en bloc resection of the pectoralis major muscle was performed. The pathologic diagnosis revealed a high-grade dedifferentiated liposarcoma with extensive necrosis. This tumor type is primarily described in the retroperitoneum and extremities. We report an unusual presentation of a liposarcoma mimicking a breast mass.
我们报告了一例男性去分化脂肪肉瘤的罕见病例。一名60岁男性患者，左乳区出现一个肿块，累及整个乳房区域，无淋巴结肿大，在一年时间内持续生长。影像学检查显示一个含脂肪的混合密度肿块，明显与胸大肌有关。进行了一次粗针活检，诊断为高分化脂肪肉瘤。进一步安排了检查转移情况的测试，未发现远处病变。实施了左乳房切除术并整块切除胸大肌。病理诊断显示为高级别去分化脂肪肉瘤伴广泛坏死。这种肿瘤类型主要见于腹膜后和四肢。我们报告了一例罕见的脂肪肉瘤表现为乳房肿块的病例。
