Testicular Metastasis as an Initial Manifestation of Gastrointestinal Cancer

Metastatic small bowel tumors in the testes are uncommon often indicating an advanced stage of sickness with poor prognosis. The route of spread to the scrotal level has not yet been defined. The most of these tumors are diagnosed at autopsy or orchiectomy for metastatic carcinoma. The diagnosis is mainly based on histological and immunohistochemical data. In this paper, we report the case of a 36-year-old patient with a spermatic torsion secondary to a testis metastasis from an adenocarcinoma of the small intestine confirmed histologically, occurring as first clinical manifestation that was taken care in the medical oncology department of CHU Hassan II in Fes. The aim of the subject is to highlight this rare metastatic localization of gastrointestinal cancer; how to approach the diagnosis and distinguish between primary testicular cancer and testicular metastasis; by describing the different clinical, radiological and anatomopathological aspects of metastatic gastrointestinal cancer to the testis.
