[Neonatal testicular ischemic necrosis without torsion, associated with antithrombin III deficit].

There have been few reports of neonatal ischemic necrosis of the testis without torsion of the spermatic cord, which may be caused either by compression in utero or by transient torsion of the spermatic cord resolving spontaneously before surgery. The patient reported herein developed an inflammatory swelling of the right scrotum and an ecchymotic plaque over the left thigh at four days of age. Ischemic necrosis of the right testis without torsion was found upon surgery. When the patient was ten days of age, he developed an inflammatory swelling in the left scrotum; ischemic necrosis of the left testis without torsion was again found upon surgery. Thrombosis of the spermatic vessels was suspected. Postoperatively, ecchymotic and necrotic skin lesions developed, followed by pulmonary embolism and cerebral thrombosis. Outcome was fatal. Hematologic tests in the neonate and his parents established the diagnosis of inherited antithrombin III deficiency. Ischemic necrosis of the testes was thus probably due to hypercoagulability. No similar cases have been reported to date.
