title: Testis metastasis as an initial manifestation of an occult gastrointestinal cancer.
abstract: Metastatic epithelial malignant tumor involving the spermatic cord and epididymis is rare and the prognosis of these patients is poor. Usually gastrointestinal cancers show diffusion to liver, lung and bone. Several routes by which a colorectal cancer can metastasize to the testis have been reported in literature. Herein we report a case of an occult gastrointestinal cancer with an intrascrotal metastasis in an adult patient with possible spread through the spermatic veins due to primary intestinal carcinoma. In the case of a testicular mass or hydrocele evidence in a patient with an unusual age for primary testis tumor, a diagnosis of metastatic cancer should be considered.
