Incidence, Risk Factors, and Clinical Presentation
Testicular tumors are very rare in young boys and account for an incidence of 1% to 2% of all childhood tumors.[1,2] The most common testicular tumors are benign teratomas, followed by malignant nonseminomatous germ cell tumors. For more information, see Childhood Extracranial Germ Cell Tumors Treatment.
Non–germ cell tumors such as sex cord–stromal tumors are exceedingly rare in prepubertal boys. In a small series, gonadal stromal tumors accounted for 8% to 13% of pediatric testicular tumors.[3,4] Most gonadal stromal tumors present as a painless testicular mass, while 10% to 20% of patients may have endocrine manifestations such as precocious puberty.[5]
In newborns and infants, juvenile granulosa cell and Sertoli cell tumors are the most common stromal cell tumors. Sertoli cell tumors present later in infancy (median age, 7 months). Juvenile granulosa cell tumors usually present early in infancy (median age, 6 days).[5] These tumors account for less than 5% of all neoplasms in the prepubertal testis. Testicular juvenile granulosa cell tumors harbor recurrent loss of chromosome 10 and lack the GNAS and AKT1 variants described in their ovarian tumor counterparts.[6]
In older males, Leydig cell tumors are more common.[7] In a report of 12 patients with Leydig cell tumors (aged 4.2–14.7 years), precocious puberty was the presenting symptom in 7 of 12 patients.[8][Level of evidence C1]
Testicular Sertoli cell tumors and, possibly, Leydig cell tumors are associated with the DICER1 syndrome. Patients with these tumors should undergo genetic testing for DICER1 germline variants.[9]
Large-cell calcifying Sertoli cell tumor is a rare testicular sex cord–stromal tumor that primarily affects young males. These tumors are usually benign, may occur in both testes, and some patients may have slow and indolent courses.[10] Large-cell calcifying Sertoli cell tumors may indicate an underlying genetic predisposition, such as Peutz-Jeghers syndrome or Carney complex.[11] Carney complex is an autosomal dominant, multisystem tumor disorder [12] that is most frequently caused by germline variants in the PRKAR1A gene.[13] A retrospective multi-institutional analysis of 15 patients with large-cell calcifying Sertoli tumor (median age, 16 years) included 4 patients with Carney complex.[14] Loss of cytoplasmic PRKAR1A expression (evaluated by immunohistochemistry) was observed in all but one patient (14 of 15; 93%). PRKAR1A expression was retained in all other sex cord–stromal tumors, indicating that such testing may aid in the diagnosis of this rare tumor entity.

Prognosis
The prognosis for patients with sex cord–stromal tumors is usually excellent after orchiectomy.[1,2,3]; [4][Level of evidence C1] In a review of the literature, 79 patients younger than 12 years were identified. No patient had high-risk pathological findings after orchiectomy, and none had evidence of occult metastatic disease, suggesting a role for a limited surveillance strategy.[5][Level of evidence C1]

Treatment of Childhood Testicular Cancer
The European Cooperative Study Group for Pediatric Rare Tumors within the PARTNER project (Paediatric Rare Tumours Network - European Registry) has published comprehensive recommendations for the diagnosis and treatment of sex cord–stromal tumors in children and adolescents.[1]
Treatment options for childhood testicular cancer (non–germ cell tumors) include the following:
- Surgery.
There are conflicting data about malignant potential in older males. Most case reports suggest that in pediatric patients, these tumors can be treated with surgery alone.[2,3][Level of evidence C1]; [4][Level of evidence C2] It is prudent to check alpha-fetoprotein (AFP) levels before surgery. Elevated AFP levels usually indicate a malignant germ cell tumor. However, AFP levels and decay in levels are often difficult to interpret in infants younger than 1 year.[5]
Evidence (surgery):
- In a study of patients prospectively reported to the German Maligne Keimzelltumoren (MAKEI) registry, 42 patients with sex cord–stromal tumors were identified. All tumors were confined to the testes. Patients were treated with surgery alone, according to specific germ cell tumor guidelines.[6][Level of evidence C1]
- There were no recurrences.
- A French registry identified 11 boys with localized sex cord–stromal testicular tumors. All 11 boys were treated with surgery alone.[7][Level of evidence C1]
- There were no recurrences.
- The benign behavior of pediatric non–germ cell testicular tumors has led to reports of testis-sparing surgery.[8,9,10,11,12] In one series of 12 patients with Leydig cell tumors (aged 4.2–14.7 years), 3 were treated with enucleation alone, and 9 were treated with orchiectomy.[13][Level of evidence C1]
- All patients were alive at the last follow-up.
Given the rarity of this tumor, the surgical approach in pediatrics has not been well defined.

Special Considerations for the Treatment of Children With Cancer
Cancer in children and adolescents is rare, although the overall incidence has been slowly increasing since 1975.[1] Referral to medical centers with multidisciplinary teams of cancer specialists experienced in treating cancers that occur in childhood and adolescence should be considered. This multidisciplinary team approach incorporates the skills of the following health care professionals and others to ensure that children receive treatment, supportive care, and rehabilitation that will achieve optimal survival and quality of life:
- Primary care physicians.
- Pediatric surgeons.
- Radiation oncologists.
- Pediatric medical oncologists/hematologists.
- Rehabilitation specialists.
- Pediatric nurse specialists.
- Social workers.
- Child-life professionals.
- Psychologists.
- Fertility specialists.
For information about supportive care for children and adolescents, see the summaries on Supportive and Palliative Care.
The American Academy of Pediatrics has outlined guidelines for pediatric cancer centers and their role in the treatment of pediatric patients with cancer.[2] At these pediatric cancer centers, clinical trials are available for most types of cancer that occur in children and adolescents, and the opportunity to participate is offered to most patients and their families. Clinical trials for children and adolescents diagnosed with cancer are generally designed to compare potentially better therapy with current standard therapy. Most of the progress made in identifying curative therapy for childhood cancers has been achieved through clinical trials. Information about ongoing clinical trials is available from the NCI website.
Dramatic improvements in survival have been achieved for children and adolescents with cancer. Between 1975 and 2020, childhood cancer mortality decreased by more than 50%.[3,4,5] Childhood and adolescent cancer survivors require close monitoring because side effects of cancer therapy may persist or develop months or years after treatment. For information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors, see Late Effects of Treatment for Childhood Cancer.
Childhood cancer is a rare disease, with about 15,000 cases diagnosed annually in the United States in individuals younger than 20 years.[6] The U.S. Rare Diseases Act of 2002 defines a rare disease as one that affects populations smaller than 200,000 people. Therefore, all pediatric cancers are considered rare.
The designation of a rare tumor is not uniform among pediatric and adult groups. In adults, rare cancers are defined as those with an annual incidence of fewer than six cases per 100,000 people. They account for up to 24% of all cancers diagnosed in the European Union and about 20% of all cancers diagnosed in the United States.[7,8] Also, the designation of a pediatric rare tumor is not uniform among international groups, as follows:
- A consensus effort between the European Union Joint Action on Rare Cancers and the European Cooperative Study Group for Rare Pediatric Cancers estimated that 11% of all cancers in patients younger than 20 years could be categorized as very rare. This consensus group defined very rare cancers as those with annual incidences of fewer than 2 cases per 1 million people. However, three additional histologies (thyroid carcinoma, melanoma, and testicular cancer) with incidences of more than 2 cases per 1 million people were also included in the very rare group because there is a lack of knowledge and expertise in the management of these tumors.[9]
- The Children's Oncology Group (COG) defines rare pediatric cancers as those listed in the International Classification of Childhood Cancer subgroup XI, which includes thyroid cancers, melanomas and nonmelanoma skin cancers, and multiple types of carcinomas (e.g., adrenocortical carcinomas, nasopharyngeal carcinomas, and most adult-type carcinomas such as breast cancers, colorectal cancers, etc.).[10] These diagnoses account for about 5% of the cancers diagnosed in children aged 0 to 14 years and about 27% of the cancers diagnosed in adolescents aged 15 to 19 years.[4]
Most cancers in subgroup XI are either melanomas or thyroid cancers, with other cancer types accounting for only 2% of the cancers in children aged 0 to 14 years and 9.3% of the cancers in adolescents aged 15 to 19 years.
These rare cancers are extremely challenging to study because of the low number of patients with any individual diagnosis, the predominance of rare cancers in the adolescent population, and the lack of clinical trials for adolescents with rare cancers.
Information about these tumors may also be found in sources relevant to adults with cancer, such as Testicular Cancer Treatment.
