Skeletal metastases from renal cell carcinoma (RCC) are common, but its metastasis to the digital extremities is rare. The lesion presents diagnostic and therapeutic challenges because of the mimicry of other benign skeletal diseases resulting in difficulties in prompt recognition of diagnosis. We here report a 62 year-old male patient with RCC metastatic to a metacarpal bone presenting with pain and swelling of left hand after 8 years’ follow-up at stable disease without any recurrences. The pathological cytology from the swelling site revealed findings consistent with metastatic clear cell carcinoma.
