Abstract

Background: Renal cell carcinoma (RCC) is the most common type of kidney cancer. About 25% of people with RCC have already developed metastatic illness. The lungs, brain, and bones are the most commonly afflicted organs by metastases. On the other hand, skin metastases account for just about 3% of all metastatic cases.
Case Description: A 53-year-old man presented with right-sided loin swelling, which was identified as a lipoma and planned for elective surgery later. Presented to the emergency department 9 months later with a 2-week history of right upper limb weakness. Further tests with a computed tomography scan revealed that the patient had primary renal cell carcinoma with brain, lung, and skin metastases.
Conclusion: Early diagnosis of skin metastases for primary renal cell carcinoma requires immediate therapy.
