The presentation of gastric carcinoma with a metastasis in skeletal muscle is a distinct rarity.
In a 72-year-old male patient a soft tissue mass behind the knee was biopsied rather late. Histology showed a metastasis of adenocarcinoma. The patient mentioned a slight feeling of strangulation, which led to endoscopy and the diagnosis of gastric carcinoma. Palliative chemotherapy was initially successful but the patient died after 21 months.
Based on this case history, three points are discussed: how to biopsy a peripheral soft tissue mass, how to proceed when a metastasis of an unknown primary tumor is diagnosed, and the epidemiology of metastases to skeletal muscle.
胃癌伴骨骼肌转移的情况极为罕见。
一名72岁男性患者，膝后软组织肿块活检较晚。组织学检查显示为腺癌转移。患者提及有轻微的哽噎感，这促使进行了内镜检查并诊断为胃癌。姑息化疗起初取得成功，但患者在21个月后死亡。
基于该病例，讨论了三点：如何对周围软组织肿块进行活检，当诊断出未知原发肿瘤转移时如何处理，以及骨骼肌转移的流行病学情况。
