Abstract:
Background : The first intraparenchymal testicular cyst in a human being was recorded by Copper in 1845, but it was subsequently shown to be a cystic teratoma, making simple testicular cysts an uncommon ailment.
Case presentation: A pediatrist sent a one-year-old child to the urology department with a diagnosis of right-sided
hydrocele.Under ultrasound guidance, we aspirated the cyst through the
scrotum. The aspiration was a 2 ml clear serum-like fluid. Everything was
normal during the first year of follow-up. After two years, the boy was
brought back to the department due to recurrent testicular
enlargement.Then it was discovered that it was a cystic teratoma.
Conclusion: In the differential diagnosis of testicular transilluminating masses in babies, testicular teratoma should be considered even in cases when ultrasonography reveals a completely cystic lesion. The initial tests that direct the subsequent course of treatment include ultrasonography and serum markers such as Alpha-1-Fetoprotein(AFP) and Human Chorionic Gonadotropin(HGC).
