title: Testicular lymphangiectasis in Noonan's syndrome.
abstract: We describe a boy with testicular lymphangiectasis and Noonan's syndrome. Both testes showed seminiferous tubules with a reduced tubular diameter, containing few spermatogonia. The testicular interstitium exhibited a number of large, dilated lymphatic vessels forming irregular channels among the seminiferous tubules and surrounding them. Since there was no accompanying pathological condition to indicate an obstruction to the lymphatic flow at the level of the spermatic cord or in the regional lymph nodes, the abnormal development of testicular lymphatic vessels suggests a congenital malformation.
