We report on a case of juvenile granulosa cell tumor of the testicle in a neonate, a rare testicular tumor in children. No genital ambiguity, anatomic abnormalities, nor sex chromosome aneuploidy was noted in this patient. In our case, despite positive staining for alpha-fetoprotein which is most consistent with yolk sac tumors, all clinical, gross anatomic, histologic, and other immunohistologic characteristics of the tumor remained consistent with the diagnosis of juvenile granulosa cell tumor. The alpha-fetoprotein positivity of the tumor remains unexplained...

We describe a case of testicular tumor with multiple metastasis to the lung,retoroperitoneal lymph node, and brain. After chemotherapy the retroperitoneal lymph node and brain metastasis disappeared,but the multiple pulmonary metastases but not disappear,although they were reduced in size. Since the human chorionic gonadotoropin (HCG) was persistently dected at a low level,we performed a testosterone tolerance test. The HCG level became undetectable for a while,but was detected at a low level again. Then the patient underwent residual tumor removal of some of the residual pulmonary disease,which was diagnosed as tumor necrosis...

We report a case of metachronous bilateral testicular tumors combined with hydrocele. A 46-year-old male presented with frequently recurrent left hydrocele. His medical history included a stage IIA right testicular tumor,which had been treated with right high orchiectomy and retroperitoneal lymph node dissection 22 years ago. Magnetic resonance imaging (MRI) showed hydrocele and a low intensity area in the left testis,and the patient underwent left high orchiectomy. After cytological examination of the hydrocele it was categorized as class V,and after a pathological study it was diagnosed as seminoma and embryonal carcinoma...

BACKGROUND: Retroperitoneal lymph node dissection (RPLND) is an important component of the management of testicular germ cell tumor (GCT) but carries significant surgical morbidity. OBJECTIVE: To describe our experience with a midline extraperitoneal (EP) approach to RPLND for seminomatous and nonseminomatous GCT. DESIGN, SETTING, AND PARTICIPANTS: From 2010 to 2015, 122 consecutive patients underwent RPLND from a prospective database. Patients requiring aortic resection or retrocrural dissection or with intraperitoneal disease were excluded...

PURPOSE: To evaluate the relationship between our proposed sonographic classification of testicular tumors by tissue harmonic imaging and histological type. METHODS: We retrospectively analyzed 58 testicular tumors and tumor-like lesions [seminomatous germ cell tumor (SGCT): 28; non-seminomatous germ cell tumor (NSGCT): 16; lymphoid and hematopoietic tumor (LHT): 7; Leydig cell tumor: 1; epidermal cyst: 2; and tumor of paratesticular structure (TPS): 4]. We divided a sonographic image into six types for morphological criteria and three types for color Doppler criteria...

INTRODUCTION: We evaluate the clinical outcome of patients treated with conservative approach for small testicular masses (STMs). We analyzed the steps who brought to the selection of the therapeutic approach: starting from clinical presentation, through imaging and lab studies. METHODS: We considered 18 patients who underwent an organ-sparing approach for STMs from 2005 until 2014. The selection criteria were dimension of the mass and absence of clinical, laboratory and/or radiological malignancy suspicion...

BACKGROUND: Syncytin-1 and 2, human fusogenic glycoproteins encoded by the env genes of the endogenous retroviral loci ERVWE1 and ERVFRDE1, respectively, contribute to the differentiation of multinucleated syncytiotrophoblast in chorionic villi. In non-trophoblastic cells, however, the expression of syncytins has to be suppressed to avoid potential pathogenic effects. Previously, we have shown that the transcriptional suppression of ERVWE1 promoter is controlled epigenetically by DNA methylation and chromatin modifications...

Cystic trophoblastic tumor (CTT) has been described in postchemotherapy retroperitoneal lymph node dissections of patients with testicular germ cell tumors. Prognostically, this lesion is similar to teratoma and no further treatment is required after surgery in the absence of other components. CTT has not, however, been reported in the testis. We identified 14 CTTs in the treated (4) and untreated (9; no information for 1 patient) testes of patients 15 to 43 years old (median, 25) with mixed germ cell tumors...

OBJECTIVES: To update previously reported outcomes of modified template postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) in appropriately selected patients with metastatic non-seminomatous germ cell tumor (NSGCT). Our previous report was criticized for short follow-up. Herein, we provide a long-term update on this cohort. MATERIALS AND METHODS: One hundred patients with normal serum markers after cisplatin-based chemotherapy and residual retroperitoneal tumor underwent modified PC-RPLND between 1991 and 2004...

Germ cell tumors (GCT) are a rare form of childhood cancer that originate from the primordial germ cell. Recent genome-wide association studies (GWAS) have identified susceptibility alleles for adult testicular GCT (TGCT). We test whether these SNPs are associated with GCT in pediatric and adolescent populations. This case-parent triad study includes individuals with GCT diagnosed between ages 0-19. We evaluated 26 SNPs from GWAS of adult TGCT and estimated main effects for pediatric GCT within complete trios (N=366) using the transmission disequilibrium test...

REVIEW
Jin-Ho Choi, Han-Wook Yoo
Steroid 21-hydroxylase deficiency is the most prevalent form of congenital adrenal hyperplasia (CAH), accounting for approximately 95% of cases. With the advent of newborn screening and hormone replacement therapy, most children with CAH survive into adulthood. Adolescents and adults with CAH experience a number of complications, including short stature, obesity, infertility, tumor, osteoporosis, and reduced quality of life. Transition from pediatric to adult care and management of long-term complications are challenging for both patients and health-care providers...

Cassy M Spiller, Josephine Bowles
Germ cell neoplasia in situ is the non-invasive precursor cell of origin for type II testicular germ cell tumors. It has long been postulated that germ cell neoplasia in situ is derived from defective germ cell development during embryonic life, and although it is impossible to trace in vivo the progression from fetal germ cell to germ cell neoplasia in situ to tumor, there is a large volume of evidence supporting this theory. Current studies focus on understanding how germ cell neoplasia in situ forms, how these cells are activated at puberty and how they transform to invasive tumors of various subtypes...

Studies have suggested mosaic loss of chromosome Y (mLOY) in blood-derived DNA is common in older men. Cohort studies investigating mLOY and mortality have reported contradictory results. Previous work found that a 1.6 Mb deletion of the AZFc region on the Y chromosome (the 'gr/gr' deletion) is associated with both male infertility and increased risk of testicular germ cell tumors (TGCT). We investigated whether mosaic loss across the entire Y chromosome was associated with TGCT. We obtained blood- and buccal-derived DNA from two case-control studies: the NCI Familial Testicular Cancer Study (cases=172; controls=163) and the NCI US Servicemen's Testicular Tumor Environmental and Endocrine Determinants Study (cases=506; controls=611)...

The testicular tumor metastatic spread via the lymphatic system, and the anatomical distribution of this, finds his target in the retroperitoneal nodes. Male patient 28 years old with a history of bilateral orchidopexy is presented. It was performed a left orchiectomy and a biopsy of the ulcerated right inguinal mass, with diagnosis of malignant teratoma. Metastatic testicular tumors in inguinal nodes are extremely rare. However, we believe that in patients with a history of scrotal surgeries and inguinal mass, must suspect for a testicular cancer...

OBJECTIVE: We investigated the prognostic value of preoperative neutrophil-to-lymphocyte ratio (NLR) on germ cell testicular tumors (GCT). MATERIAL AND METHODS: The data of 53 patients who underwent inguinal orchiectomy were analyzed retrospectively. NLR was calculated from the preoperative complete blood cell counts. Receiver operating characteristic (ROC) analysis was performed to find the threshold values for NLR. Correlations between cancer-specific survival (CSS) and progression-free survival (PFS) and NLR were evaluated...
