A 71-year-old man visited our hospital for examination of a soft neck mass. Computed tomography and magnetic resonance imaging scans showed a well-circumscribed large lipomatous tumor with multiple nodules inside. Atypical lipomatous tumor or lipoma involving the lymph nodes was considered. Pathological examination of the surgical specimen suggested typical lipoma including multiple metastatic foci from gastric cancer. Subsequent endoscopy revealed a gastric tumor, which was histologically proven to be signet-ring cell carcinoma. Considering these findings, this case was diagnosed as tumor-to-tumor metastasis to lipoma. We present the first such case with imaging and clinical characteristics.
一名71岁男性因颈部软性肿块来我院检查。计算机断层扫描和磁共振成像扫描显示一个边界清晰的大脂肪瘤性肿瘤，内部有多个结节。考虑为非典型脂肪瘤或累及淋巴结的脂肪瘤。手术标本的病理检查提示为典型脂肪瘤，包括来自胃癌的多个转移灶。随后的内镜检查发现一个胃肿瘤，组织学证实为印戒细胞癌。综合这些发现，该病例被诊断为肿瘤向脂肪瘤的肿瘤转移。我们呈现了首例具有影像学和临床特征的此类病例。
