Abstract
Children, adolescents and young adults with testicular germ cell tumors require appropriate surgical care to insure excellent outcomes. This article presents the most critical elements, and their basis in evidence, for surgery in this population. Specifically, the importance of inguinal radical orchiectomy for malignant tumors, partial orchiectomy for prepubertal tumors and normal serum tumor markers, and the appropriate use of post-chemotherapy retroperitoneal lymph node dissection in those with residual retroperitoneal masses.

Abstract
Testis-sparing surgery (TSS) has been increasingly used for treating a variety of testicular tumors (TTs) in children. However, the indications and feasibility associated with TSS remain uncertain. This study aimed to present the clinical outcomes of TSS in children with TTs. The PubMed, Cochrane Library, and Embase databases were reviewed for relevant articles on the clinical outcomes of TSS in children. Recurrence rate, benign rate, rate of TSS and its 95% confidence interval (CI) were calculated. A total of nine relevant studies with 320 patients were included in this study. The recurrence rate was 5.8% (95% CI: 2.3%-14.1%), benign rate was 70.9% (95% CI: 56.3%-82.1%), the rate of TSS (RTSS) was 36.2% (95% CI: 26.1%-47.8%), RTSS in benign tumor was 48.4% (95% CI: 34.3%-62.9%) and rate of elevated AFP was 29.3% (95% CI: 19.7%-41.3%) in children with TTs. Regarding the distribution of TTs, 159 (49.6%) were teratomas, 74 (23.1%) were yolk sac tumors, 36 (11.3%) were epidermoid cysts, 3 (0.9%) were rhabdomyosarcomas, 7 (2.2%) were leydig cell tumor, 6 (1.8%) were sex-cord stromal tumor, 8(2.5%) were mixed malignant germ cell tumors, 3(0.9%) were hemangioma, and 4(1.3%) were adrenal rest tumors. The findings of this meta-analysis suggested that most of the TTs in children were benign, and the most common histologic subtype was teratoma. TSS should be provided to children with benign lesions. This study confirmed that very low rates of tumor recurrence were observed in children with TTs.

Abstract
While radical orchiectomy remains the gold standard for testicular cancer, partial orchiectomy has become a well-accepted organ-sparing approach for benign testicular tumors in pre-pubertal patients. The aims of testicular-sparing surgery include prevention of over-treatment, preservation of future hormonal and reproductive function, and provision of a durable cure. For pre-pubertal patients, who have a high likelihood of benign lesions, partial orchiectomy provides effective treatment, owing to the high reliability of scrotal ultrasound (US) and intraoperative frozen section. In adolescent and young adult patients, who are more likely to harbor malignant pathology, the role of partial orchiectomy is less clear. Testis-sparing surgery is being reported with greater frequency in the adult literature for small testicular masses and for situations in which radical orchiectomy would result in an anorchia. More recently, a testis-sparing approach has also been described for carefully-selected post-pubertal pediatric patients. This review will highlight the role of partial orchiectomy in pediatric patients (<18 years old).

Abstract
In prepubertal boys, testicular tumors are rare with an incidence between 2 and 5/million. In contrast to testicular tumors in adolescents and adults, more than 2/3 of these tumors are benign. Unfortunately, in Germany in most cases, only malignant tumors (usually yolk sac tumors) are reported to the study center (MAKEI IV and now V). Therefore, the incidence in Germany is unknown. Since the introduction of polychemotherapy in the 1970s, the prognosis of malignant testicular tumors has improved enormously and has become a curable disease, even in the case of recurrence. Today the orchiectomy, which was usually carried out in the past, appears to be no longer justified in most prepubertal boys due to the high incidence of benign tumors. It has been shown in various studies that organ-sparing surgery in germ cell tumors (epidermoid cysts, teratoma); gonadal stoma tumors (Sertoli, Leydig and granulosa cell tumors) and cystic lesions (intratesticular cysts and tubular ectasia of the rete testis) is reliable and safe. In cases with preoperative significantly increased AFP (caution: norm values not valid in the first year of life) and a clear testicular tumor in the ultrasound (yolk sac tumor) or if no testicular parenchyma is sonographically detectable, orchiectomy can still be carried out. Today orchiectomies in prepubertal boys should be an exception and the reasons for an orchiectomy must be well documented.

Abstract
Testicular tumors are rare in children but highly treatable and usually curable. Seminomas are extremely rare in prepubertal children. Among nonseminomatous germ cell tumors, the most common are teratomas and yolk sac tumors. Mixed germ cell tumor (MGCT) contains more than one germ cell component. MGCT is very rare in prepubertal age group. Here, we are presenting a case of MGCT in a newborn child with a review of literature. It is the first reported case in the world literature.

Abstract
Abstract
Background
Measurement of α-fetoprotein (AFP) concentrations in the serum of infants is useful for the management of testicular germ cell tumors, hepatoblastoma and hepatocellular carcinoma. Here, we provide a critical review of the available information about pediatric reference intervals (RI), focusing on their utility in interpreting AFP as an aid for cancer diagnosis.
Content
Evidence sources in the available literature were critically appraised. Out of 3873 retrieved papers, 24 were finally selected and carefully inspected, and six of them overcame exclusion criteria (i.e. methodological limitations in the study design, statistical gaps, drawbacks in traceability of the AFP assay to higher order materials and/or biased reporting of AFP results). Preterm and term infants up to the 3rd month of life exhibited the highest average AFP concentrations, but the attempt of defining RI by data pooling and partitioning for age intervals was impeded by the wide variability of data. The inability of defining robust RI in the first months of life made difficult, if not impossible, using upper reference limits for ruling out malignancies with a single AFP result. Evaluating the behavior of AFP concentrations 5 days from the baseline result, if this exceeds risk thresholds partitioned for age, according to the formula Xt=X0*2−t/HL (where: t=days elapsed for AFP retest; HL=AFP half-life according to age; X0=AFP baseline concentration, and Xt=predicted AFP concentration at day 5), could give a better information.
Summary
Novel studies defining AFP RI in infants based on robust methodology are warranted to improve the interpretation of AFP results in pediatric oncology. In the meantime, algorithms based on both serum AFP absolute concentrations and HL may aid in cancer diagnosis.

Abstract
INTRODUCTION Prepubertal testicular tumors are fundamentally distinct from their postpubertal and adult counterparts. Racial and ethnic differences contribute to the incidence, characteristics, and histological distribution of prepubertal testicular germ cell tumors (PTGCTs). OBJECTIVE To elucidate the characteristics and treatment outcomes of PTGCTs in a Chinese cohort. STUDY DESIGN Data were retrospectively reviewed from consecutive PTGCT patients aged <12 years who received treatment at the current institution from January 2007 to December 2015. Exclusion criteria were: patients aged >12 years, non-primary testicular germ cell tumors, and para-testicular tumors. RESULTS A total of 167 patients qualified for the study (Table). The median age at diagnosis was 20 months (range 1-142). Pathology revealed 87 (50.9%) teratomas, 50 (29.2%) yolk sac tumors (YSTs), 33 (19.3%) epidermoid cysts, and one (0.6%) mixed germ cell tumor. Of the teratomas, 70 (80.5%) mature teratomas (MTs) and 17 (19.5%) immature teratomas (ITs) were detected. ITs manifested at a younger age and were larger in size compared with MTs (P < 0.001). Testis-sparing surgery (TSS) was performed for all MTs and 10 ITs. Radical orchiectomy (RO) was performed for seven ITs. No metastatic or local recurrence was detected in benign tumors during follow-up. Obviously elevated alpha fetoprotein (AFP) levels were detected in all the YSTs. Of these, 47 (94%) were diagnosed as Stage I, one (2%) as Stage II, and two (4%) as Stage IV. After RO, recurrence was detected in one Stage I patient with a median follow-up of 46 months. One Stage II and two Stage IV patients died due to tumor progression. DISCUSSION Racial and ethnic differences were detected in PTGCTs. It is believed that the present study is the largest study detailing the clinicopathologic characteristics and treatment outcomes of PTGCTs in a Chinese cohort. CONCLUSIONS Teratoma was the most common subtype of PTGCTs, followed by YST. ITs manifested as benign behavior and were more likely to be present at a younger age and have a larger tumor size compared with MTs. TSS was reliable for benign lesions. For Stage I YST, RO alone was valid. Salvage chemotherapy was effective and preventative retroperitoneal lymph node dissection may not be necessary for YST. The prognosis of PTGCTs was favorable.

Abstract
BACKGROUND Testicular cancer is the most common cancer in young men in developed countries. In adults, international variation in testicular cancer incidence rates has been well-described, while previous research on pediatric and adolescent testicular cancer has been more geographically limited. METHODS In this analysis, we used data from the three most recent volumes of Cancer Incidence in Five Continents (CI5) and the National Cancer Institute's SEER 18 registries to compare incidence rates for testicular cancer in children (ages 0-14) and adolescents and young adults (AYA; ages 15-39). RESULTS We find that geographic incidence patterns in AYA are different from patterns in children under 15. In AYA, incidence is highest in Europe (137.4 per million), followed by Oceania (116.9 per million), North America (94.9 per million), South and Central America (66.5 per million), and lowest in Asia (27.1 per million). In contrast, childhood incidence is highest in Asia (4.2 per million) and South America (5.0 per million) and lowest in Europe (2.1 per million) and North America (2.5 per million). In the United States, patterns in incidence rates in racial and ethnic groups mirror international rates. CONCLUSION These differences in incidence rate variations in pediatric and AYA testicular cancer are intriguing and may aid in understanding the different etiologies of testicular cancer by age group.

Abstract
INTRODUCTION Leydig cell hyperplasia (LCH) and Leydig cell tumours (LCTs) in children are rare, typically presenting with precocious puberty. Previously, orchidectomy was the routine management; however, more recently, testis-sparing surgery has been performed with good results. We present a series of unusual presentations of LCH, raising new management questions, and a review of the literature regarding LCH and LCT in children. STUDY DESIGN We performed a literature search using Ovid Medline, PubMed, and Google Scholar, producing 456 articles. We reviewed all case reports and series containing paediatric patients, and relevant review articles. RESULTS We report three cases of LCH, two of which were incidental findings. All three cases underwent testis-sparing surgery. In the literature there were seven cases of LCH and 101 cases of LCT in prepubertal children. The most common presentation was with precocious puberty. Three cases of LCH and more than two-thirds of LCTs were managed with orchidectomy and overall only 11% of the cases underwent testes-sparing surgery (24% did not specify operative management). There were no reports of recurrence or malignancy. DISCUSSION Our case series presents three new clinical presentations of LCH that have not previously been reported in the literature: one of incomplete precocious puberty and two with incidental findings on ultrasound in asymptomatic children. Historically, children with the classic presentation of precocious puberty and a testicular lesion have been managed with orchidectomy. Nowadays, many clinicians advocate testes-sparing surgery given there have been no cases of malignancy. In children with no clinical or biochemical signs of precocious puberty, lesions identified on ultrasound can be safely monitored for a period of time. However, if the lesion does not regress, excisional biopsy is recommended to establish the diagnosis, ideally before the onset of puberty. CONCLUSION Leydig cell hyperplasia and tumours in pre-pubertal children are benign. Testes-sparing surgery with regular follow-up appears to be safe management.

Abstract
Organ-sparing approaches have been applied to the treatment of a variety of urologic tumors in both the realms of adult and pediatric urology, with the goals of minimizing overtreatment of benign lesions, preserving function, and providing durable cure. The predominance of benign tumors in prepubertal patients and the reliability of both ultrasound and intraoperative frozen sections have resulted in a marked shift toward testis-sparing approaches over the last few decades. The role of testis sparing in the adolescent population is presently unclear, although there have been increasing reports of successful organ-sparing surgery for testis tumors in the adult literature. This review presents recent trends in testis-sparing approaches for both pediatric and adolescent patients, the operative technique, and some of the controversies related to testis-sparing surgery.

Abstract
Prepubertal testicular tumors are rare compared with postpubertal testicular tumors. The incidence of prepubertal testicular tumors peaks at 2 years of age, tapers off after 4 years of age, and then begins to rise again at puberty. Prepubertal and postpubertal testicular tumors show many differences, including the typical tumor histology, molecular biological differences, and the malignant potential of tumors at different ages. Pediatric testicular tumors are classified as benign or malignant on the basis of their clinical behavior and histologically are divided into germ cell and gonadal stromal (nongerm cell) tumors. Many histological and biological studies have further confirmed the distinct nature of prepubertal and postpubertal testicular tumors. These differences have led to various management strategies for prepubertal and postpubertal tumors. Because overall about 75% of prepubertal testicular tumors are benign, a testis-sparing approach is becoming more common in children. Orchiectomy and observation with very selective use of chemotherapy has become the standard approach when a malignant tumor is identified. Retroperitoneal lymph node dissection and radiation therapy play very limited roles.

Abstract
BACKGROUND Teratomas are a spectrum of neoplasms that can undergo malignant transformation. In the World Health Organization (WHO) classification of tumors, this entity was classified as «teratoma with somatic-type malignancy», was defined as a malignant neoplasm of non-germinal phenotype that originates in a teratoma. MATERIALS AND METHODS We present a serie of nine cases of testicular teratomas with secondary malignant transformation. From January 1995 to December 2011, we found a total of 306 cases of testicular tumors. Mixed germ cell tumors were the most frequently diagnosed malignancy with 45.7%. RESULTS Teratoma with secondary malignant transformation, represented 2.9% of all germinal tumors. Five cases originated within a mixed germ cell tumor, two cases from mature teratomas, and two from immature teratomas. The predominante malignant somatic component were sarcomas; two cases of chondrosarcoma, one rhabdomyosarcoma, and one case showing foci of chondrosarcoma and rhabdomyosarcoma. The case of osteosarcoma is notable for its rarity. Two cases showed epithelial malignancy in the form of an adenocarcinoma, and finally, two cases were primitive neuroectodermal tumors. At the time of diagnosis, five patients had metastases. CONCLUSION The transformation of germ cell tumors to somatic type malignancies is rare. The malignant component can originate from any of the three germ lines. These tumors are resistant to standard chemotherapy for a germ cell tumor and the clinical stage is the most important prognostic factor. At our institution, the malignant component that appeared most frequently was chondrosarcoma.

BACKGROUND/PURPOSE Intratesticular cysts are a rare clinical entity in the pediatric population. Recently, testes sparing surgery has been recommended. We share our experience with the management of pediatric testicular cysts. METHODS A retrospective review of all pediatric patients referred for intratesticular cysts was conducted at a single pediatric institution from 2002 to 2010. Charts were evaluated for patient demographics, diagnosis, and management. RESULTS Seven patients were identified and included in this series. After partial orchiectomy, the final diagnosis in three patients was epidermoid cyst. Three further patients were diagnosed as mature cystic teratoma, with two of these demonstrating adjacent intra-tubular germ cell neoplasia (ITGCN). One cyst in the series underwent spontaneous resolution after eight months. CONCLUSION All of the cystic lesions in our case series were benign with one undergoing complete resolution. The remainder became smaller and developed a solid component prompting surgery. The pre-pubertal findings of ITGCN in two patients raise a dilemma regarding the optimal long-term management for these patients. Initial conservative observation is an option for the majority of pre-pubertal cystic testicular lesions until such time that testis sparing surgery is deemed technically feasible. Testes sparing surgery should be advocated in those patients undergoing surgical management.

Abstract
STUDY TYPE Therapy (case series). LEVEL OF EVIDENCE 4. What's known on the subject? and What does the study add? Testicular tumours in childhood are very rare. Historically, most of these tumours have been considered malignant, but more recent studies indicate that benign lesions, particularly teratoma, are much more frequent than previously thought. Testicular tumours in this age group have traditionally been treated with inguinal radical orchiectomy, but more conservative management has been proposed in view of the higher frequency of benign tumours. In children, most testicular tumours are benign, especially before puberty. A testis-sparing procedure should be performed in children with a palpable testicular mass and negative tumour markers. OBJECTIVE To report our experience of testicular tumours in children aged≤13 years, including our experience with testis-sparing surgery. PATIENTS AND METHODS A retrospective study was performed of 15 patients with testicular tumours aged≤13 years who presented at our centre between 1984 and 2008. The use of testis-preserving surgery according to indication was investigated and outcomes were recorded. RESULTS The clinical presentation was increased testicular size with a palpable mass in 80% of the cases. All 15 patients underwent surgery. The tumour was benign in 12 (80%) patients and malignant in three (20%) patients. Organ-preserving surgery was planned and achieved in 11 patients (73%). Pathology of the tumourectomy specimens disclosed benign tumours in all cases: four epidermoid cysts, two teratomas, one juvenile granulosa cell tumour, one haemangioma, one lipoma, one fibrous hamartoma and one splenogonadal fusion. In four patients who underwent radical orchiectomy, pathology identified one yolk sac tumour (stage I), two mixed germ cell tumours and one gonadoblastoma. CONCLUSIONS In children, most testicular tumours are benign, especially before puberty. A testis-sparing procedure should be performed in children with a palpable testicular mass and negative tumour markers. The lesion, however, should be thoroughly excised to avoid recurrences.

Abstract
INTRODUCTION prepubertal testicular tumours are different from those that appear during adulthood. Traditionally, they were considered to be malignant, however benign testicular tumours are actually more frequent at this age. MATERIALS AND METHODS we analysed our experience in the treatment of testicular tumours in children ≤ 13, with the intention of evaluating the use of partial orchiectomy. From 1984 to 2008, we diagnosed and treated 15 testicular tumours in children at our centre. We examined the therapeutic approach employed, underlining the possibility of testicular conservation in selected patients and we have analysed the results. RESULTS the clinical presentation in 80% of the cases was an increase in testicle size with palpable mass. We performed 4 radical orchiectomies (27%) and 11 tumourectomies (73%). All the benign lesions in the final pathological anatomy were treated with tumourectomy: four epidermoid cysts, one hemangioma, one lipoma, one fibrous hamartoma, one juvenile granulosa tumour and one splenogonadal fusion. We also successfully and conservatively treated two cases of teratoma. The cases that received radical treatment were a yolk sac tumour (Stage I), two mixed germ cell tumours and one gonadoblastoma. CONCLUSIONS there are more cases of benign testicular tumours than malignant tumours during puberty. In the event of a palpable testicular mass with negative tumour markers, conservative treatment by means of a tumourectomy may be considered. However, the lesion must be removed completely to prevent recurrence.

Abstract
AIMS Glypican 3 (GPC3) has been reported to be overexpressed in yolk sac tumour (YST), but the sensitivity has not been compared with alpha-fetoprotein (AFP). YST can form numerous growth patterns and the expression of GPC3 in these patterns has not been studied. The aim was to address these aspects. METHODS AND RESULTS Sections from testicular or ovarian YST were subjected to immunohistochemistry using GPC3 (n = 39) and AFP (n = 24). Overall immunoreactivity for each case and specific histological patterns were semiquantitatively evaluated (0-3+) and intensity of reactivity was scored (0-3). All cases expressed GPC3 (1+, 5%; 2+, 8%; 3+, 87%) with strong intensity (2.9). The majority expressed AFP (58%) but immunoreactivity was often focal (0, 42%; 1+, 33%; 2+, 25%) and intensity was low (1.0). Using GPC3, >75% of the microcystic (n = 38), macrocystic (n = 26), solid (n = 21), glandular-alveolar (n = 8), endodermal sinus (n = 7), polyvesicular vitelline (n = 5), enteric (n = 4) and micropapillary (n = 2) growth patterns displayed 2+ or 3+ positivity. CONCLUSIONS YST can display a variety of growth patterns that can be confused with other germ cell tumour components. GPC3 detects all growth patterns tested and has a higher sensitivity for detecting YST than AFP.

Abstract
Technological advances in imaging as well as increased knowledge of tumor-specific biology have promoted the role of organ-sparing approaches to pediatric renal and testicular tumors. Application of these techniques continues to evolve as data on long-term follow-up become available and as protocol-guided investigation provides answers to therapeutic outcomes of these approaches. Optimally, organ-sparing surgery will continue to provide increased potential for preservation of both renal function and fertility.

Abstract
Prepubertal testicular and paratesticular tumours are a rare group of tumours, distinct from postpubertal paediatric and adult tumours of this region. Tumours within this group are testicular germ-cell tumours (such as benign teratoma, epidermoid cyst and malignant yolk-sac tumours) and stromal tumours (such as juvenile granulosa-cell, Leydig-cell, and Sertoli-cell tumours). Paratesticular tumours can be benign (lipoma, leiomyoma, haemangioma) or malignant (rhabdomyosarcoma, melanotic neuroectodermal tumour of infancy). Because of their rarity, centralised pathology and treatment, and national collaborative clinical trials have been important in establishing the optimum management of malignant tumours in this group. We provide an up-to-date and comprehensive review of the clinical presentation, imaging, pathology, and clinical management of prepubertal paratesticular and testicular tumours.

Abstract
BACKGROUND Due to the rarity of testicular tumors in the prepubertal population, adequate information about their biological course is difficult to document well in a single institution. The purpose of this study was to focus on prepubertal males in an attempt to evaluate clinical features and optimal management among various testicular germ cell tumors with long-term follow-up. METHODS We retrospectively reviewed the records of children younger than 12 years of age with primary testicular germ cell tumors between February 1981 and December 2005 at Taipei Veterans General Hospital. Thirty-four children were diagnosed with adequate clinical and pathologic data. The stage of the disease was determined according to the staging system used by the Children's Oncology Group. Mean follow-up time was 139 months (range, 2-283 months). RESULTS All of the 34 prepubertal patients were diagnosed initially with a painless scrotal mass. The mean age of the patients at diagnosis ranged from 6 months to 84 months (mean, 20.5 months). All patients underwent radical orchiectomy as an initial treatment. Twenty-nine (85.3%) patients had yolk sac tumors, and 5 (14.7%) had mature teratomas. Of the 29 patients with yolk sac tumor, 26 (89.7%) were diagnosed as stage I, 1 (3.4%) as stage III, and 2 (7.0%) as stage IV. Five (19.2%) of the 26 stage I yolk sac tumors progressed to metastasis after radical orchiectomy, and all of these 5 patients later received chemotherapy. One patient initially with stage III yolk sac tumor and 2 patients with stage IV yolk sac tumor were also treated with chemotherapy. Eventually, 1 patient with stage IV yolk sac tumor died due to tumor progression; the remaining 28 patients with yolk sac tumor all survived without tumor relapse after appropriate treatment. In the 5 patients with teratomas, there was no tumor relapse after radical orchiectomy with a mean follow-up time of 139.1 months. The 5-year survival rates for yolk sac tumor and teratomas were 96.5% and 100%, respectively. CONCLUSION The most common prepubertal malignant testicular tumor is yolk sac tumor, and the most common benign testicular tumor is teratoma. Children with testicular germ cell tumors have excellent long-term survival rates after appropriate treatment.

Abstract
CONTEXT More than 90% of testicular neoplasms originate from germ cells. Testicular germ cell tumors (GCTs) are a heterogeneous group of neoplasms with diverse histopathology and clinical behavior. OBJECTIVE To help the readers distinguish various subtypes of GCTs, to highlight the clinical manifestations and pathologic features of these tumors, and to review several newly developed immunohistochemical markers for GCTs. DATA SOURCES Review of the pertinent literature and our experience. CONCLUSIONS The etiology of GCTs is largely unknown. Cytogenetic studies suggest a different pathogenesis for each group of infantile/prepubertal GCTs, postpubertal GCTs, and spermatocytic seminoma. Unclassified intratubular germ cell neoplasia is the precursor of all GCTs, excluding spermatocytic seminoma and infantile/prepubertal GCTs. Seminoma, the most common GCT in adults, does not occur before 5 years of age. Spermatocytic seminoma, a tumor of elderly men, typically has an indolent clinical behavior, but rarely it undergoes sarcomatous transformation associated with an aggressive behavior. Embryonal carcinoma is the most common component in mixed GCTs. Eighty percent or more of embryonal carcinoma component and vascular invasion are recognized predictors of occult metastasis for clinical stage I mixed GCTs. Most patients with prepubertal yolk sac tumor, the most common pediatric GCT, have stage I disease at presentation. Most choriocarcinomas present with metastatic symptoms because of the propensity for rapid hematogenous dissemination. Teratomas in children regardless of maturity and dermoid cysts in adults are benign; in contrast, teratomas in adults have a malignant behavior. With appropriate therapy, the majority of testicular GCTs are curable.

Abstract
OBJECTIVE To report our experience of testicular and paratesticular tumours in children, as such tumours are rare, and historically yolk sac tumour has been described as the most common lesion in children, but recent reports suggest that benign testicular lesions might be more common. PATIENTS AND METHODS We reviewed retrospectively the records of children treated for testicular tumours from 1998 to 2005. The patients' age, clinical presentation, diagnostic procedures, treatment methods, histopathological findings, and outcome were recorded. Patients aged>144 months and those with non-primary metastatic lesions were excluded. RESULTS In all, 11 patients met our criteria, with a mean age of 37 months (range 9 days to 144 months). Pathological analysis revealed teratoma in four patients, yolk sac tumour in two, epidermoid cysts in two, extrarenal nephroblastomatosis in one, and paratesticular rhabdomyosarcomas in two. The most common clinical presentation was a painless testicular mass. Depending on the clinical presentation and pathology, scrotal ultrasonography, tumour markers (alpha-fetoprotein and beta-human chorionic gonadotrophin), and/or staging computed tomography (CT) were obtained in eight patients. All patients had a radical orchidectomy. Three patients had elevated tumour markers that normalized after orchidectomy. CT revealed extensive mediastinal adenopathy in one patient with rhabdomyosarcoma. Chemotherapy was administered to both patients with rhabdomyosarcoma. CONCLUSION Although there were few patients, most of the lesions were benign tumours, with the most common histological subtype being teratoma. As both malignant and paratesticular lesions occurred at a significant frequency, we would continue to advocate an initial radical inguinal approach at which time testis-sparing could be considered if the preoperative evaluation was favourable, and frozen-section analysis at the time of surgery confirms a benign lesion.

Abstract
Seminomas are very rare tumours in children and adolescents. We describe a case of seminoma in a 15-year-old boy who was managed with orchidectomy but no adjuvant therapy. He remains relapse-free 8 years after surgery as determined by clinical, radiological and serological surveillance. This study emphasizes the uncertainty over the need for adjuvant treatment in the management of seminoma in the adolescent patient, in particular in prepubescent children.

Abstract
PURPOSE We reviewed the current diagnosis, staging and management of testicular and paratesticular neoplasms in prepubertal males. MATERIALS AND METHODS We performed a medical literature search in English using MEDLINE/PubMed that addressed testicular and/or paratesticular neoplasms in prepubertal males. We then analyzed the literature with respect to individual tumors. We present a concise approach toward the management of these individual tumors. RESULTS There is still a predominance of yolk sac tumors in prepubertal males, although some studies suggest that teratomas are more common but underreported due to their benign course in children. Prepubertal males are diagnosed in a fashion similar to that in adult patients with an appropriate history and physical examination. A palpable, nontender mass suggests the diagnosis and prompts scrotal ultrasound and tumor markers. Although treatment for most primary tumors has historically been radical inguinal orchiectomy, most benign tumors can now be managed by testis sparing surgery. The addition of radiation, chemotherapy and/or retroperitoneal lymph node dissection depends on tumor stage and histological type. CONCLUSIONS Although it is rare in children, any solid scrotal mass in prepubertal males warrants evaluation for possible testicular or paratesticular neoplasm.

Abstract
Teratomas in an undescended testis are rare in infants. This report was the youngest case of immature teratoma originating in intra-abdominal undescended testis. A 3-month-old infant with cryptorchism was seen because of an asymptomatic palpable mass in the right abdomen. Ultrasonography and computed tomography revealed a multicystic large tumor with focal calcifications in the right side and serum tumor markers within normal limits. Complete resection of the tumor was performed and the histopathological diagnosis was made as immature teratoma of the right testis. Because retroperitoneal lymph nodes metastasis was observed in 3-month follow-up postoperatively, retroperitoneal lymphadenectomy and chemotherapy including bleomycin, etoposide, and cisplatin were performed. Presently, the infant has been free of recurrence for 3 years. We suggest that nonpalpable testis should undergo a careful evaluation and prompt resolution and that the subsequent finding of an intra-abdominal mass should make us think on the possibility of intra-abdominal testicular germ cell tumor. Postoperative adjuvant chemotherapy in combination with complete resection of the tumor is necessary for pediatric immature teratomas originating in intra-abdominal undescended testis.

Abstract
OBJECTIVES To evaluate the importance of testicular and paratesticular prepubertal tumors in our center and to make an update on the topic. METHODS AND PATIENTS Data from all patients diagnosed of testicular and paratesticular prepubertal tumors and treated in our pediatric oncology unit from January 1st 1998 to December 31st 2003 have been revised. RESULTS Seven cases are reported among one hundred and ninety patients (represents 3,68 percent of all treated tumors): five tumors affecting the testis and two cases of paratesticular tumors. Pathology classification was as follows: one yolk sack tumor, one mature teratoma, two nongerminomatous testicular tumors (one Sertoli cell tumor and one unclassifiable), one Burkitt's lymphoma and two paratesticular rhabdomyosarcomas. Primary approach was inguinal radical orchiectomy in all cases except neoadjuvant chemotherapy in the case of lymphoma and partial escrotectomy in one patient previously managed with transcrotal orchiectomy. Rhabdomyosarcoma cases received adjuvant chemotherapy. All patients are alive and well after a follow-up period ranging from 17 to 74 months. CONCLUSIONS Testicular and paratesticular prepubertal tumors are rare. Except for one patient affected of lymphoma, surgical primary approach have been essential for treatment. The prognoses in this series has been excellent.

Abstract
PURPOSE Testicular teratoma is a rare neoplasm affecting the pediatric population and has classically been reported to be the second most common testis tumor in children behind yolk sac tumors. Testicular teratomas are benign and partial orchiectomy may be considered. We describe our single institution experience with testicular teratoma and definitive treatment with testis preserving surgery. MATERIALS AND METHODS We reviewed the pathology records at our institution for all testicular and paratesticular tumors diagnosed between 1976 and November 2002 in males younger than 18 years. We specifically examined the prepubertal incidence of teratoma, including epidermoid cysts, and our experience with testis preserving surgery. Preoperative and postoperative ultrasonography images were used to calculate the atrophy index following surgery. Patients were contacted for long-term followup. RESULTS Of 77 primary testicular and paratesticular tumors 38 were diagnosed in prepubertal boys (age younger than 13 years) including 11 mature teratomas and 5 epidermoid cysts. Mean patient age at treatment was 34.4 months (range 4 months to 10 years). All boys presented with a painless scrotal mass, cystic foci within an intratesticular mass on ultrasound and a normal alpha-fetoprotein level. Of the 16 boys with benign teratomas 13 (81%) were treated with a testis sparing procedure. At a mean 7-year followup no patient has presented with recurrent tumor in the ipsilateral or contralateral testicle. Postoperative physical examination and scrotal ultrasound were obtained in 9 patients at a median followup of 10.2 months, and there was no evidence of testicular atrophy or persistent discomfort. CONCLUSIONS Unlike previously published series based on tumor registries, benign teratoma was the most common pediatric testicular tumor treated at our institution. Our single institution experience with testis preservation and long-term followup confirms the role and safety of this technique. Testis sparing surgery remains our technique of choice for testicular teratoma.

Abstract
PURPOSE The aim of this study was to present an updated picture of surgical management of pediatric testicular tumors based on our 30 years' experience, which consisted of one of the largest noncollected series treated in a single medical center. METHODS Records of children who were treated for testicular tumor in our unit from 1970 to 1999, inclusive, were reviewed retrospectively. Information recorded for each patient included age, sex, past medical history, clinical characteristics, diagnostic procedures, treatment methods, histopathologic findings, and outcome. RESULTS Fifty-one patients with a mean age of 3.8 +/- 0.5 years were treated for testicular tumors. Of these, 35 (69%) had germ cell testis tumor (GCT) and 16 (31%) had non-germ cell testis tumor (NGCT). Endodermal sinus tumor and paratesticular rhabdomyosarcoma were the dominant histologic subtypes in each group, respectively. The most common mode of presentation was painless scrotal mass. At initial presentation, retroperitoneal (n = 5), both retroperitoneal and lung (n = 2), and retroperitoneal and liver (n = 3) metastases were recorded in 10 (19%) patients. Initial operative procedures were radical inguinal orchiectomy (RIO) (n = 29), scrotal orchiectomy (SO; n = 9), bilateral RIO (n = 2), both RIO and unilateral retroperitoneal lymph node (RPLN) excision (n = 6), testis-sparing enucleation of the tumor (n = 5). SOs were performed elsewhere, and these patients underwent high ligation (n = 4) and both high ligation plus RPLN excision (n = 5) in our unit. Histopathologically, spermatic cord invasion and RPLN involvement were present in 10 patients. Scrotal recurrences were encountered in 2 patients who had scrotal orchiectomy initially. Retroperitoneal recurrences were noted in a patient presenting with stage I embryonal carcinoma and in 2 patients presenting with group IV paratesticular rhabdomyosarcoma. The mean follow-up period was 89 +/- 10 months. Four patients with stage IV embryonal carcinoma (n = 2) and group IV paratesticular rhabdomyosarcoma (n = 2) died of progression of the disease. All remaining patients were alive and disease free at their last outpatient appointment. No significant difference was noted with regard to 5-year survival rates between (1) malignant GCT and paratesticular rhabdomyosarcoma patients (91% v 80%) and (2) patients treated by RIO (88%), SO plus high ligation (87%), and RIO plus RPLN excision (80%). Five-year survival rates were 100% for stage I, II, III patients and 33.3% for stage IV and group IV patients presenting with malignant testicular tumors (P <.05). CONCLUSIONS Childhood testicular tumors deserve special attention from the therapeutic point of the view. A solid scrotal mass should be considered malignant until proved otherwise. Any suspicion of the testicular tumor warrants an inguinal approach to prevent scrotal violation by the tumor. Current trends emphasize that testis-sparing surgery should be performed for benign lesions such as teratoma, leydig cell tumor, and epidermoid cyst based on frozen biopsy findings. Literature findings and our experience suggest that RIO is the accurate treatment for stage I malignant GCT and group I and IIa paratesticular rhabdomyosarcoma. RPLN excision is not of benefit either as a staging or therapeutic procedure in stage I and group I and IIa diseases of these tumors. RPLN excision should be reserved for (1) malignant GCT patients who have persistent elevation of alpha-fetoprotein after orchiectomy in the presence of normal total body CT scan, and for patients presenting with stage II and III disease with definitive abnormality on CT scans, and (2) group IIb, IIc, and III paratesticular rhabdomyosarcoma patients with radiologic evidence of retroperitoneal involvement on CT scans. High ligation should be done as a complementary procedure after SO to increase the survival rates. J Pediatr Surg 36:1796-1801.

Abstract
Testis germ cell tumor is the most frequent cancer in men between 15 and 35 years old. The therapeutic results of radical orchiectomy and chemotherapy reaches 90% free disease survival al the present time. This great chemosensibility is opening new doors to alternative therapeutic options, directed to preserve the sufficient amount of tissue to avoid the problems derived from testicular insufficiency. Such alternatives are clearly beneficial in bilateral germinal tumors or in solitary testis. In this article we describe a case of seminoma developed in a solitary functional testis managed in a conservative approach: organ preserving surgery and surveillance. We analyzed the indications and international results of such approach based on the best evidences now available.

Abstract
One can strongly suspect a benign lesion in a prepubertal child on the basis of preoperative sonographic, biochemical, and clinical evaluation; however, when considering a testis-sparing enucleation, the definitive diagnosis must be established by pathologic frozen section of the tumor. The high incidence of benign testicular lesions in the prepubertal patient, the absence of associated carcinoma in situ in prepubertal germ cell tumors, and the universally benign behavior of the specific tumors described in this article are supportive evidence for testis-sparing surgery versus orchiectomy, for these benign lesions.

Abstract
Yolk sac tumor is the most frequent germ cell tumor of testis in children. For stage I yolk sac tumor of testis in children younger than 2 years, high inguinal orchiectomy alone has been the standard treatment, with a cure rate of at least 75%. Here, we compare the treatment results of receiving chemotherapy or no chemotherapy after orchiectomy, to analyze the role of chemotherapy. From February 1987 to January 1997, 22 children younger than 2 years, with stage I yolk sac tumor of testis, were included in the study. All patients had high inguinal orchiectomy without retroperitoneal lymphadenectomy. Initial diagnostic imaging studies included computed tomographic scan of abdomen, chest radiography, and long bone survey. Clinical stage I was defined as a tumor completely resected with no evidence of local regional lymph node involvement or distant metastases. Serum alpha-fetoprotein (AFP) was assessed at diagnosis. After orchiectomy, diagnosis, and staging, patients were stratified into two treatment groups, with or without chemotherapy, according to the decision of the parents. Ten children received chemotherapy consisting of cisplatin, vinblastine, and bleomycin (PVB, modified "Einhorn regimen") for 12 weeks. The remaining 12 patients were followed up according to a "wait and see" policy. Determination of AFP was performed monthly during the first postoperative year, every other month during the second year, every 3 months during the third year, every 6 months during the fourth year, and yearly until the fifth postoperative year at least. The duration of follow-up ranged from 3 months to 119 months (median, 53 months). The Kaplan-Meier plot estimated an overall survival rate of 91.6% at 7 years after diagnosis. Among the 12 patients without chemotherapy, 2 children had relapses at 4 and 6 months after diagnosis, respectively. One was cured with PVB chemotherapy. The other patient died with refractory lung metastasis, in spite of intensive multimodality salvage therapy. The Kaplan-Meier plot showed a survival rate of 80% at 7 years and a relapse-free survival rate of 81.8% at 5 years after diagnosis. All children receiving chemotherapy were alive and free from relapse. There was no significant treatment-related toxicity. Our results may suggest that PVB chemotherapy after orchiectomy is an affective and safe regimen for stage I yolk sac tumor of testis in children younger than 2 years. Instead of four courses of PVB as used here, two or three courses could be enough. To elucidate the necessity for chemotherapy and to determine the number of courses of PVB needed (if chemotherapy is given), a randomized study of more cases is warranted.

Abstract
Pediatric patients presenting with painless scrotal masses can be perplexing because of the long differential diagnosis. A careful plan based on the physical examination and sonogram findings localizes the mass to the testis or an extratesticular location. Sonography distinguishes solid from cystic lesions. Subsequent management is based on the location and nature of the mass. Intratesticular masses are assumed to be malignant, but testis-sparing surgery is possible in pediatric patients. Extratesticular cystic lesions are likely benign and are managed according to the specific diagnosis. Solid extratesticular lesions require exploration to establish the correct diagnosis.

Abstract
If a tumor arises in a solitary testis the patient loses fertility and requires lifelong androgen substitution. We describe the technique and results of organ preserving enucleation resection performed in 14 patients. The tumor was excised under (cold) ischemia via a mini-surgical technique using 2-fold magnification and blood vessels were localized intraoperatively by Doppler sonography. The procedure was successful in 10 of 14 patients. In 2 patients the organ required ablation later because of insufficient blood supply. Two patients had subnormal testosterone levels after treatment. There were no local recurrences. Prerequisites for this type of treatment are detailed knowledge of the vascular anatomy of the testis, tumor not too close to the rete testis, largest diameter 20 mm. or less, normal preoperative plasma testosterone level, postoperative local irradiation with 20 Gy., followup biopsies and hormonal status obtained 6 months after enucleation resection, and meticulous followup for early detection of local recurrences or systemic progression.

Abstract
In the Danish Cancer Registry, 72 testicular tumours in boys younger than 15 years of age were recorded during the period 1943-1989 and material from 34 of these was retrieved from Danish departments of pathology. The histological types were evaluated and the role of immunohistochemical staining was analysed. The survival of the patients was correlated with the histological diagnoses, and changes in the incidence of testicular cancers in childhood were analysed. Twenty-nine of the 34 patients had germ cell tumours, which fell into two groups (infantile and pubertal) with distinct differences. The tumours of infancy usually presented before the age of 3 years and were either pure yolk sac tumours or teratomas. The tumours of puberty showed no morphological or immunohistochemical differences from adult germ cell tumours. In the infantile group, immunohistochemical staining confirmed the morphological evaluation but was not necessary for diagnosis. Patients in the infantile group seemed to have a better prognosis than adult patients, only one patient dying from his disease, whereas the pubertal patients seemed to have a prognosis similar to that of adult patients. The incidence of infantile testicular cancer in Denmark appears to have increased at almost the same rate as that observed in adult men, but due to the small numbers in infancy, this cannot be statistically substantiated. We conclude that the testicular germ cell tumours of infancy and puberty may arise from different precursor cells, but both groups seem to arise prenatally.

Abstract
Between 1971 and 1993, 12 children with testicular germ cell tumors were treated at the Department of Urology, Faculty of Medicine, Kyoto University. Seven patients had yolk sac tumors and 5 had mature teratoma. Of the 7 patients with yolk sac tumors 6 had stage I and 1 had stage III tumors. Initial management of the stage I tumors consisted of high orchiectomy in 5 patients and high orchiectomy plus retroperitoneal lymph node dissection in 1 patient. Of these 6 patients, 4 were cured by surgery alone but lung metastases developed in the other 2 patients. One of them was salvaged with thoracotomy and chemotherapy but the other died of tumor. The patient with stage III tumor had bulky tumor spread to lung and retroperitoneum, but seems to have been cured by chemotherapy followed by resection of the residual mass although follow-up is still inadequate (14 months). Six of the 7 patients (85.7%) are alive 13 months to 21 years after diagnosis. Five patients with mature teratoma were treated by high orchiectomy or, more recently, enucleation and all are alive 4 months to 22 years after surgery.

Abstract
Testicular and paratesticular neoplasms are uncommon tumors of childhood. Consequently, the experience gained with regard to their optimal management is limited in any given children's cancer centre. Here we review the classification, diagnosis, and staging of testicular and paratesticular neoplasms and subsequently discuss the more frequently occurring ones: germ cell tumors, gonadal stromal tumors, gonadoblastoma, tumors of the supporting tissue, lymphomas and leukemias, tumor-like lesions, secondary tumors, and tumors of the adnexa.

Abstract
Testicular neoplasms constitute 1 percent of all childhood malignancies and rank eighth in childhood cancer mortality. From 1970 to 1988, 25 testicular tumors in children eighteen years and under were seen. The majority of the patients were white (88%). Pathologic analysis of the tumors revealed that 68 percent were germinal and 32 percent were nongerminal. Staging was undertaken in all patients with serum markers, chest x-ray film, and computerized tomography scans or lymphangiography. All patients underwent radical orchiectomy, and further therapy was given dependent on tumor type and stage. The survival among this cohort was excellent, with only 3 patients succumbing to their disease. Detailed results of treatment, and approaches to avoid excess treatment morbidity are reviewed.

Abstract
We report on 5 patients 14 months to 6 1/2 years old with prepubertal teratoma of the testis treated by testicular sparing tumor enucleation. All 5 patients had no evidence of recurrence at a mean followup of 96 months. Recognizing that this is not accepted therapy for testis tumors, 17 orchiectomy specimens containing teratoma from children were histologically analyzed in cooperation with the Armed Forces Institute of Pathology Tumor Registry. All patients were prepubertal at orchiectomy (3 months to 8 years old) and all are well with a mean followup of 174 months. Histological examination revealed no foci of teratoma separate from the main tumor in any specimens. Immunohistochemical studies with placental alkaline phosphatase, a marker for malignant germ cells, were done to detect carcinoma in situ in the seminiferous tubules of these testes. This test did not reveal any intratubular malignant germ cells (carcinoma in situ). Based on our clinical experience with testicular sparing tumor enucleation, the histological findings on Armed Forces Institute of Pathology review demonstrating no associated carcinoma in situ and the universally benign behavior of prepubertal testicular teratomas, we recommend a testicular sparing operation rather than orchiectomy for testicular teratoma in prepubertal patients.

Abstract
In 1980 the Section on Urology of the American Academy of Pediatrics established a registry of prepubertal testicular tumors. A total of 181 yolk sac tumors has been reported to the registry. Complete followup is available for 154 of these 181 patients. Most of the patients presented with low stage disease. Radical orchiectomy without adjunctive retroperitoneal lymphadenectomy, chemotherapy or radiotherapy was sufficient therapy for most stage 1 cancer patients. alpha-Fetoprotein is a reliable marker for this tumor. Chest x-rays and abdominal computerized tomography are reliable for staging. When metastases appeared they did so within 14 months of presentation so that 2 years of followup after any evidence of disease seems to be adequate. Approximately two-thirds of the patients with metastases were salvaged by chemotherapy, radiotherapy and/or an operation.

Abstract
Testicular self-examination has been proposed as a screening technique for the early detection of testicular neoplasms. Previous work suggests that few adolescent males have received instruction in the technique. We report the results of a physician survey to assess the frequency with which self-examination is taught and to identify the reasons why some physicians do not teach testicular self-examination. Only 17.5% of the physicians surveyed taught testicular self-examination to adolescent male patients on a routine basis. Eighty-two percent stated that they were unfamiliar with the technique or had not thought about it.
