A three-month-old female infant presented with abdominal distention for 2 months. A large palpable mass in right upper quadrant was noted on physical exam. Abdominal ultrasound revealed a large heterogeneous mass with multiple cystic components. Mass was surgically excised and pathology was consistent with mature adrenal teratoma. Teratoma is a germ cell tumor mainly found in gonadal tissues. Occurrence of adrenal gland teratoma in children is very rare with less than 10 pediatric case reports in English literature...

PURPOSE: To examine the clinical presentation, treatment and results in children and adolescents with primary mediastinal (PM) and retroperitoneal (RP) germ cell tumors (GCTs). METHODS: The TGM95 trial for malignant GCTs was conducted in France between 1995 and 2005 to evaluate a strategy adapted to prognostic factors with cisplatin-based chemotherapy and surgical management. We reviewed patients with TGCTs at PM and RP sites. RESULTS: Among 239 patients, there were 16 patients with PM and 5 with RP tumors, which represent 9% of all patients, highlighting the rarity of these extragonadal locations...

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...

BACKGROUND: Pediatric germ cell tumors account for approximately 3.5 % of all childhood cancers for children under the age of 15 years. Up to one-third are extragonadal neoplasms. Germ cell tumors are a heterogeneous group of malignant tumors with a wide variety of histopathological features. Yolk sac tumor is the predominant variant in newborns and younger children. We report for the first time, the presentation of a primary yolk sac tumor in the abdominal wall of a small child. CASE PRESENTATION: An 18-month-old white girl underwent resection of a small, round subcutaneous lump (1...

BACKGROUND: Ovarian tumors are uncommon in childhood and constitute around 1% of childhood malignancies. Two thirds of pediatric ovarian tumors are germ cell tumors. Epithelial ovarian tumors and stromal tumors are less frequent. We share our experience in childhood ovarian cancers, analyzing a series of cases with respect to the clinical profile, treatment and survival. METHODS: All newly diagnosed ovarian tumors in children up to 14 years of age, registered in our Pediatric Oncology Division between January 2000 and December 2009 were retrospectively reviewed...

The skills of adult versus pediatric neuro-oncologists are not completely similar though additive. Because the tumors and their protocols are different and the tolerance and expected sequelae are specific. Multidisciplinary meetings including adult and pediatric neuro-oncologists are warranted to share expertise. Since 2008, a weekly national web based conference was held in France. Any patient with the following criteria could be discussed: Adolescent and Young Adults aged between 15 and 25 years, and any adult with a pediatric type pathology, including medulloblastoma, germ cell tumors, embryonic tumors, ependymoma, pilocytic astrocytoma...

PURPOSE OF REVIEW: As pediatric oncology has become more complex, designing and maintaining pediatric surgical protocols require greater expertise. The primary purpose of this review is to summarize the changes in protocols and new study findings, which have changed surgical practice for children with solid tumors. RECENT FINDINGS: The most common solid tumors treated by surgery are reviewed. There are new methods of surgical techniques such as the use of sentinel lymph node techniques for the assessment of lymph nodes in pediatric sarcoma...

Management of extracranial germ cell tumors (TG) is emblematic of the adolescents and young adults' problematic. Beyond persisting differences in care between adult and pediatric oncologists, it emphasizes the need for effective collaboration between both teams. If the therapy is primarily guided today by adult standards, pediatricians bring expertise in long-term follow-up, justified by the increasing description of late side effects in this young population, with highly curable disease since cisplatin's emergence...

In adolescents and young adults (AYA), cancers are rare but represent the third significant cause of death. The aim of this paper was to investigate epidemiological data and pathways of care of AYA in France. During the 2000-2008 period, overall age-standardized incidence rates (ASR) were 254.1/10(6) in 15-24-year-olds. The most frequently diagnosed cancers in male AYA were malignant gonadal germ-cell tumors and Hodgkin's lymphoma, and were melanoma, thyroid carcinoma and Hodgkin's disease in females. The ASR appeared stable over time...

Benign testicular teratomas are always thought to be pediatric neoplasms and previously all the teratoid tumors in the adult testis regarded as malignant. Recently, three publications reported benign testicular teratomas in adulthood and the latest WHO classification refers them as "prepubertal type of teratomas" which rarely appear in adulthood. These neoplasms behave benign and seemingly analogous independently whether they appear in pre- or postpubertal patients. The aim of our study was to investigate the frequency of benign testicular teratomas both in children and adults...

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...

Vinodh Pillai, David M Dorfman
Many epithelial neoplasms can be analyzed by flow cytometry (FC), particularly from serous cavity effusion samples, using EpCAM, a cell adhesion molecule expressed on most normal epithelial cells and expressed at a higher level in most epithelial neoplasms. A simple 3-color flow cytometric panel can provide a high sensitivity and specificity compared to cytomorphology. FC provides more rapid immunophenotyping than conventional immunohistochemical staining, can identify rare malignant cells that could be missed by a cytological exam alone, and can be utilized to evaluate limited samples such as cerebrospinal fluid or fine-needle aspiration samples...

One of the most extraordinary stories in the chronicles of gynecologic cancers has been that of malignant ovarian germ cell tumors. Prior to the mid-1960s, most patients died of disease. Fifty years later, most survive. Precisely because high cure rates are achievable, the concentration over the past decade has been on minimizing toxicity and late effects. The present review focuses on five areas of interest related to the management of malignant ovarian germ cell tumors that highlight the different therapeutic strategies practiced by pediatric and gynecologic oncologists: 1) primary surgery, 2) surgery alone (surveillance) for patients with FIGO stage IA disease, 3) postoperative management of FIGO stage IC-III disease, 4) postoperative management of pure immature teratoma, and 5) postoperative management of metastatic pure dysgerminoma...
