Nasopharyngeal carcinoma with unusual metastasis to urinary bladder.

Nasopharyngeal carcinoma (NPC) metastasizing to urinary bladder is an uncommon site. We report an interesting case of NPC, on follow-up, presenting with unusual urinary symptoms and mimicking a primary bladder cancer. Subsequent bladder cold cup biopsy and immunohistochemistry unfolded a metastasis of NPC, highlighting unexpected and a rare presentation.
