[A case of carcinoma of the stomach revealed by a testicular metastasis (author's transl)].

A testicular metastasis from a gastric carcinoma is exceptional among the rare secondary localisations of a visceral neoplasm in the testis. It should however be remembered for the testicular tumour sometimes precedes the clinical manifestations of the primary neoplasm. The diagnosis of the testicular metastasis from a gastrict carcinoma can only be made by histological examination and required the use of slides stained with mucicarmine. The method of spread to the testis seems mainly due to inversion of the lymph flow by neoplastic obstruction of the latero-aortic lymph nodes. In the cases reported in the literature, the presence of a testicular metastasis from a carcinoma of the stomach is a factor suggesting a poor prognosis.
