ABSTRACT
Renal cell carcinoma is frequently undiagnosed until it reaches an advanced metastatic stage. Renal cell cancers are also seen as incidental findings on imaging, and rarely can present as physical examination findings. We report a rare case where metastatic renal cell carcinoma presented as a solitary 2 cm subcutaneous chest wall nodule in an otherwise asymptomatic male patient. Initial ultrasound evaluation showed a solid vascular subcutaneous mass, a fine needle aspiration suggested metastatic renal cell cancer, and later, excision biopsy, and CT scan of the abdomen made the final diagnosis of stage IV renal cell carcinoma. The differential diagnosis of a 2 cm nodule can be broad and in appropriate clinical setting should include consideration of malignancy and/ metastasis.
