Metastatic adenocarcinoma in testis presenting as a testicular mass--a case report and review of literature.

Testicular metastasis presenting as a testicular mass is an extremely rare condition. There are only nine previously reported cases where testicular mass was the first clinical manifestation of underlying malignancy. Here we report a case of metastatic mucin secreting adenocarcinoma in testis presenting as a testicular mass with unknown primary. We have given a brief review of literature about the spread of tumor to testes.
