Testicular tumors in the prepubertal age are relatively rare, representing only 9.4% of the total testicular and paratesticular specimens from a 20-year review performed at a large pediatric hospital [ 1 ]. They account for 1% to 2% of all solid tumors in the pediatric age group, with an annual incidence between 0.5/100 000 and 2/100 000 boys according to Coppes et al [ 2 ] and data from the Prepubertal Testicular Tumor Registry [ 3 ]. Similar to other neoplasms afflicting children, a bimodal age distribution is observed. The first peak is between birth and 3 years of age, and a second one occurs at the onset of puberty, extending to the fourth decade. Reports on their frequency vary because some investigators include the adolescent period, while others do not [ 4 ]. The vast majority of testicular tumors are germ cell neoplasms, accounting for 95% across all ages [ 5 ]. In children, germ cell tumors also predominate, representing 71% of all testicular neoplasms. These include yolk sac tumors (49%), teratomas (13%), seminomas and mixed germ cell tumors (9%), and sex-cord stromal tumors (29%). Malignant potential is significantly lower (less than 70%) in the pediatric age group compared to adults (90%) [ 6 ]. According to Pohl et al, 74% of prepubertal testicular tumors are benign [ 7 ].

“…The lack of vascularity in the cyst helps radiologists to distinguish epidermoid cysts from testicular malignant tumours. 5,6 A number of studies have reported the value of magnetic resonance imaging (MRI) in the diagnosis of TEC. Based on these studies, TEC may appear at MRI as concentric rings of low and high signal intensity on T1 and T2 weighted images or a peripheral rim with low signal intensity on both T1 and T2 weighted images.…”

Testis-sparing surgery in testicular mass: Testicular epidermoid cysts

We present 3 patients with testicular epidermoid cysts who experienced testis-sparing surgery. These patients had a palpable painless testicular mass and underwent inguinal testicular exploration. Intraoperative frozen section revealed no evidence of malignancy and therefore enucleation of the tumour was performed. We demonstrate that careful intraoperative frozen-section examination helps to avoid unnecessary orchidectomy in testicular epidermoid cysts.
