Mature testicular teratoma in children: multifaceted tumors on ultrasound.
OBJECTIVE
To describe the different ultrasound (US) findings of mature testicular hamartomas in children.


METHODS
This is a retrospective study from January 2000 to July 2012 that reviewed the clinical, laboratory, and US findings of 7 children with a pathologic diagnosis of mature teratoma of the testis. All patients in the study received surgery (tumorectomy or orchiectomy), and the material was examined by the institution's Pathology Department.


RESULTS
The US findings were varied and distinct. As to the lesions' consistency, they were cystic (n: 1), multicystic (n: 2), solid-cystic (n: 1), solid containing larger or smaller calcifications (n: 2), and focal calcification (n: 1). With regard to total circulation, all the solid lesions had few vessels in the interior of the lesions.


CONCLUSIONS
Testicular teratoma has a very variable US appearance and can simulate that of other lesions. It can be single, multiseptated, small, or large. It can contain diffuse or localized calcifications. The testicle can have an increased or a normal volume.
