Abstract
Neonatal testicular tumors are extremely rare. We report the case of a full-term male newborn with right hemiscrotal swelling found immediately after birth. The right hemiscrotal skin gradually turned dusky dark and then adhered to the hard scrotal contents. Missed right testicular torsion was suspected and emergency exploration was not attempted. Right hemiscrotal swelling became aggravated, so right orchiectomy and left orchidopexy were performed. During surgery, severe inflammation of the right testis and the right hemiscrotum were observed and diffuse hemorrhage with focal hematomas was noted within the removed right testis. Histopathology of the specimen revealed a ruptured mature cystic teratoma of the testis. The alpha-fetoprotein concentration was 729 × 104 μg/L 10 days after the operation, and dropped to 185 × 104, 25 × 104, and less than 20 × 104 μg/L 2, 5, and 8 months later, respectively. Postoperative abdominal and pelvic computerized tomography scans revealed neither lymphadenopathy nor distant metastasis. During a follow-up of 8 months, no evidence of tumor recurrence was found. Although extremely rare, testicular tumors should be included in the differential diagnosis of an enlarged hard or firm scrotal mass in the male neonate.
