Pulsatile Clavicular Swelling As the Sole Presentation of Asymptomatic Renal Cell Carcinoma with an Isolated Metastasis to the Clavicle: A Case Report

Renal Cell Carcinoma (RCC) is notorious for its unpredictable dissemination patterns involving both lymphatic and haematogenous route without a clear-cut preponderance for any. Unlike other intra-abdominal malignancies like colorectal carcinoma, renal cell carcinoma is often known to metastasize to distant sites even after a confident and unsuspecting curative resection or often as the primary presentation constantly adding and agitating our presentation patterns for this sneaky tumour. Presented below is a case of such an unsuspecting female patient. She was referred from the orthopaedic OPD to surgery OPD with a right clavicular swelling which was histopathologically examined and diagnosed as a metastatic renal cell carcinoma following which she was diagnosed with right renal cell carcinoma.
