Description
Luis A Huerta Diaz and colleagues reported in 2026 a diagnostic trap involving a 77-year-old man whose kidney cancer returned in an unexpected place. Twelve years after removal of a kidney for renal cell cancer, he developed a painless, growing lump near the right parotid gland and jaw muscle.
Scans showed a richly supplied, fast-flowing mass that first looked like a tangle of abnormal blood vessels. His cancer history, however, prompted a needle sample, which proved the lump was metastatic clear cell kidney cancer. Surgery removed the parotid tissue and the mass together. The case reminds clinicians that a vascular-looking head and neck lump in a patient with past kidney cancer may be a late return of that cancer.
