Free-floating Paratesticular Calcifying Fibrous Pseudotumors in a Pediatric Patient.

Paratesticular masses are a relatively common finding in males. The majority are benign, as opposed to testis masses, which tend to be malignant. Fibrous pseudotumors are rare, but are the third most common paratesticular tumor after adenomatoid and lipoma. The exact cause is unclear but likely from a fibroinflammatory reaction. Because of the non-specific findings on physical exam and scrotal ultrasound, patients may undergo scrotal exploration and occasionally orchiectomy, in spite of the benign nature of this lesion. Here we report the rare case of free-floating paratesticular calcifying fibrous pseudotumors in a prepubertal patient.
