Pediatric Case ReportsTesticular Yolk Sac Tumor and Mature Teratoma: Synchronous Bilateral Occurrence in an Infant
Section snippets
Case Presentation
A 7-month-old infant was referred to our hospital with a 1 month history of nontender, left testicular mass. Physical examination demonstrated a normal boy appearance without evidence of hydrocele or hernia. His testes were descended bilaterally. A small firm mass was palpable within the left testis and the right testis was palpably normal. Scrotal ultrasound revealed a homogeneous hypoechoic solid mass with rich blood supply in the middle-lower pole of the left testis, measuring 16 mm
Comment
Testicular YST usually presents as an asymptomatic testicular enlargement and has occurred in children under 2 years of age, characterizing by hypervascular solid mass in ultrasonography and elevation of serum AFP level.2, 3, 7, 8 In our case, the patient had an AFP of 243 ng/ml. Admittedly, the AFP may be physiologically elevated in infants; however, children aged younger than 1 year with elevated AFP >100 ng/ml should be presumed to have a yolk sac tumor.2
Cases of bilateral testicular YSTs
Conclusion
Benign lesions represent the majority of testicular masses in prepubescent children, with most that are malignant being YST. Synchronous YST and mature teratoma of the testes in children are exceedingly rare. The treatment of patients with bilateral testicular YSTs should be based upon the clinical stage, patient age, and the histopathologic type of the tumors, and refer to the standard management of the unilateral testicular YST. The reliability of both ultrasound and intraoperative frozen

Bilateral Synchronous Testicular Germ Cell Tumors in Children: Case Report and Review of the Literature
2020, UrologyCitation Excerpt :We decided to perform testicular sparing surgery since AFP values decreased after the first operation in accordance with its half-life kinetics and the US findings of the mass in the contralateral testis suggesting a benign lesion. Bilateral presentation are reported in 1%-2% of adult testicular tumors,18 however it is extremely rare in children.3-12 Only 10 published pediatric case reports were present in the English literature (Table 1).
