Metastatic tumours of the distal extremities, also known as acrometastases, are rare. The majority of the acrometastases involve bones-involvement of the soft tissues of the feet and hands is extremely rare. We report a case of clear cell renal cell carcinoma metastasised to the soft tissues of the foot. The patient presented with pain and swelling in his right foot. Diagnosis of acrometastases frequently gets delayed due to the rarity of this condition and resultant low clinical suspicion. Possibility of metastatic disease should be entertained as an important differential diagnosis when patients with a history of cancer present with musculoskeletal symptoms. A systematic evaluation incorporating thorough clinical assessment, advanced imaging techniques like MRI and pathological examination is critical to establish the diagnosis.
远端肢体转移瘤，又称肢端转移，较为罕见。肢端转移瘤多数累及骨骼，足部和手部软组织受累极其罕见。我们报告了一例发生于足部软组织的透明细胞肾细胞癌转移病例。该患者因右脚疼痛和肿胀而就诊。由于这种情况罕见，导致临床怀疑度低，肢端转移瘤的诊断经常延迟。当有癌症病史的患者出现肌肉骨骼症状时，应将转移性疾病的可能性作为重要的鉴别诊断。系统评估包括全面的临床评估、MRI 等先进的影像学技术和病理检查对于明确诊断至关重要。
