Metastatic testicular carcinoid tumour

Abstract

Carcinoid tumours occur predominantly in the gastrointestinal tract and bronchial system of the lungs, but they can originate in less common anatomical sites such as the testes, which accounts for <1% of all testicular neoplasms. Carcinoid tumour is a rare and indolent neoplasm with the potential for distant metastasis. We report on a man with metastatic right testicular carcinoid tumour who had multiple liver and bone metastases. The radiological and clinicopathological features of carcinoid tumours are also reviewed.
