[Epididymo-testicular disjunction. Presentation of 23 cases and review of the literature].

Twenty three cases of alterations of the epididymis-testicular union found in 1,000 children with cryptorchism are discussed. Anatomical and pathological findings are described and world literature on the subject is reviewed, finding very scanty references to this problem in spite of the fact that expected incidence of epididymis testicular non-junction is between 1 and 2% of the patients with cryptorchism.
