Congenital testicular lymphangiectasis in children with otherwise normal testes.

Two cases of testicular lymphangiectasis are reported, occurring in stillborns. The disease is a congenital malformation consisting of an abnormal expansive development of lymphatic vessels in both testes. Autopsy study revealed the absence of pulmonary, intestinal or systemic lymphangiectasis. The testes showed normal tubular development with normal germ cell numbers and also normal Leydig cell numbers. The epididymis and spermatic cord appeared normal. In contrast with the two previously reported cases of testicular lymphangiectasis, the present cases were not associated with cryptorchidism or other malformations.
