[Gynecomastia in chronic renal insufficiency. Presentation of a clinical case].

Gynecomastia may occur in men with chronic renal failure, developing in the course of complex endocrine abnormalities. It is often associated with aberration in the hypothalamo-pituitary-testicular axis even producing a severe hypogonadism. A case of monolateral gynecomastia in a hemodialyzed young man, without other clinical and endocrine signs, is described.
