Abstract

Urachal carcinoma is a rare malignancy of all bladder carcinomas. Metastatic lung tumours showing multiple nodules are rare without a local recurrence. We describe a case of multiple metastatic lung cancer from urachal carcinoma that required differentiation from primary lung cancer.

Keywords: adenocarcinoma; bladder; lung metastasis; urachal cancer.
