Familial transverse testicular ectopia unrelated to persistent Müllerian duct syndrome

摘要

Transverse testicular ectopia (TTE) is rare. Although several familial cases of TTE have been reported, most of them were associated with persistent Mullerian duct syndrome (PMDS), which may be inherited as an autosomal-recessive or X-linked recessive trait. We experienced two brothers with TTE unrelated to PMDS. A genetic etiology may be involved even in TTE unrelated to PMDS.
