Urinary bladder metastasis--an unusual presentation of distant spread from a primary pyriform sinus cancer: a case report.
Hypopharyngeal cancers have a high propensity to distant metastasis. However, metastasis to the urinary bladder as an initial presentation of distant spread has not been reported in literature. We present a report of a patient with a treated and controlled pyriform sinus cancer who presented with complaints of dysuria, 8 months after completion of treatment. Cystoscopy revealed a bladder mass and biopsy confirmed it to be a metastatic squamous cell carcinoma. On further investigation, the patient was found to have disseminated disease for which chemotherapy was instituted. A relevant review of literature is also presented.
