RÉSUMÉ

Testicular malignancies commonly affect adolescent and young adult males. Although they tend to respond well to cisplatin-based chemotherapy with excellent overall survival, complications such as inferior vena cava tumor thrombus are rare and can be associated with high morbidity and mortality. We present a case of tumor thrombus in a 21-year-old active duty male with a newly diagnosed stage IIIB non-seminomatous germ cell tumor presenting with extensive left lower extremity swelling. Ultrasound with Doppler was notable for significant thrombus of the left common femoral, femoral, and popliteal vein. Computed tomography imaging revealed extensive thrombus of the inferior vena cava, left iliac veins, and left gonadal vein with sparing of the left renal vein. Endovascular thrombectomy was performed with pathologic analysis confirming the presence of malignant cells consistent with tumor thrombus. The patient continued subsequent non-seminomatous germ cell tumor treatment without complications.

RÉSUMÉ

Transverse testicular ectopia (TTE) is an infrequent ectopic testis where both testes descend via the same inguinal canal, located in the same hemiscrotum, and augments the risk of developing testicular tumours. Type II TTE is accompanied by persistent Müllerian duct syndrome, where the Müllerian structures persist for various reasons. Here, we present a case of an adult in his early 30s, who presented with a right testicular swelling and was diagnosed as type II TTE and testicular mixed germ cell tumour after surgery. We could find only 13 similar cases of TTE and testicular tumours in the literature. Our case highlights the importance of clinical acumen with detailed history, meticulous clinical examination, radiological investigations and a detailed pathological examination while dealing with such sporadic presentations.

RÉSUMÉ

Gliomatosis peritonei (GP) and Growing Teratoma Syndrome (GTS) are rare and clinically significant conditions often associated with ovarian teratomas. GP involves the development of benign glial implants on the peritoneal surface, while GTS is characterised by the growth of benign, yet enlarging peritoneal implants following chemotherapy for malignant germ cell tumours. These implants are typically histologically mature teratomas devoid of malignancy. Our report documents a unique case where both GP and GTS manifested in a patient undergoing treatment for an immature ovarian teratoma. This dual occurrence is scarcely reported in the existing literature. The patient, a nulliparous woman in her 20s, developed a tumour indicative of GTS immediately after completing three cycles of bleomycin, etoposide and cisplatin therapy. This chemotherapy regimen followed fertility-sparing surgery for a stage IIIb ovarian immature teratoma. Given that total tumour resection is pivotal in positively influencing the prognosis of GTS, early minimally invasive surgical intervention before significant tumour growth is essential. This approach is particularly crucial considering that ovarian germ cell tumours are commonly present in younger patients, necessitating a focus on fertility preservation in most cases.

RÉSUMÉ

Germ cell tumors (GCTs) are a heterogeneous group of pediatric cancers. In up to one-third of male patients, a primary mediastinal location is associated with the presence of Klinefelter syndrome (KS). We describe a case of mediastinal GCT in a patient, with unacknowledged KS, that presented a relapse 7 years from diagnosis, that is, 2 years after the end of the follow-up program usually recommended for patients with GCT. There are no recommendations for screening for KS in patients with mediastinal GCT and there are no specific guidelines for surveillance of GCT in KS patients. Our experience suggests that KS should be suspected in patients with mediastinal GCT, and a longer follow-up plan should be implemented when GCT occurs in patients with KS.

RÉSUMÉ

Paraneoplastic neurologic syndromes (PNSs) are a group of diseases affecting the central and/or peripheral nervous system caused by immune-mediated processes directed toward antigens with shared expression in tumor and neural tissue. Germ cell tumors (GCTs) are associated with PNSs with varied clinical phenotypes. Early diagnosis of PNS is vital to potentially uncover and treat underlying tumors, improving the chances of recovery, and preventing permanent neurologic complications. In this chapter, we outline the pathophysiology and epidemiology of PNS. We briefly provide a summary of GCTs in males and females. We review the neural-specific autoantibodies and PNSs associated with GCTs and their clinical and radiologic accompaniments. We also provide an overview of the treatment and prognosis of these disorders.

RÉSUMÉ

BACKGROUND: Extragonadal germ cell tumors originating from the prostate are exceptionally rare. To the best of our knowledge, there have been no reported cases of mixed germ cell tumors in individuals with 46 XX disorder of sex development. In this study, we conducted a comprehensive analysis using whole genome sequencing to investigate the clinicopathological and molecular genetic characteristics of a submitted case, with the objective of elucidating its underlying pathogenesis. CASE PRESENTATION: A 40-year-old male patient was diagnosed with a combination of 46, XX disorder of sex development and a primary prostate mixed germ cell tumor with yolk sac tumor and teratoma components. Whole-genome sequencing revealed that the tumor cells had a high somatic mutational load. Analysis of genomic structural variations and copy number variants confirmed the patient's karyotype as 46, XX (SRY +). Additionally, the patient exhibited short stature, small bilateral testes, slightly enlarged breasts, elevated serum alpha-fetoprotein concentrations, elevated follicle-stimulating hormone and luteinizing hormone levels, and low testosterone levels. DISCUSSION: A case of 46, XX disorder of sex development, along with a primary prostatic mixed germ cell tumor, was diagnosed. This diagnosis has contributed to advancing our understanding of the genetic and phenotypic profile of the disease and may provide some insights for its treatment.

RÉSUMÉ

Thyrotoxicosis as the presenting syndrome of an underlying ß-hCG-secreting malignancy is well described. It has been previously theorized, but not reported, that the surge of ß-hCG secondary to chemotherapy induction may inadvertently trigger thyrotoxicosis. After thorough review, this is the first documented case of such event in peer-reviewed medical literature published in the English language. This is a case of a 21-year-old male with stage IIIc non-seminomatous germ cell tumor who developed paraneoplastic hyperthyroidism within 4 days of the first cycle of chemotherapy. Management considerations are suggested based on this case and review of the literature.

RÉSUMÉ

BACKGROUND: Testicular germ cell tumours (TGCTs) are the most common malignancy in men aged 15-40 years, with increasing incidence worldwide. About 33 ~ 50% of the patients present with metastatic disease at diagnosis. TGCT survivors experience short- and long-term sequelae, including cancer-related fatigue (CRF). Physical activity (PA) has established effects on reducing CRF and other sequelae and improving health-related quality of life (HRQoL). However, its impact on TGCT survivors has so far received little attention. The gut microbiota plays a crucial role in various physiological functions, including cognition and metabolism, and may mediate the effects of PA on CRF and other sequelae, but this has not been investigated in randomized controlled trials. METHODS: This national, multicentre, phase-III trial will evaluate the impact of a one-year supervised PA program on CRF and other short- and long-term sequelae in metastatic TGCT patients receiving cisplatin-based chemotherapy combined with etoposide+/-bleomycin. It will also investigate potential mediating effects of the gut microbiota and its metabolites involved in the gut-brain axis on the relationship between PA and CRF and other sequelae. A total of 236 men ≥ 18 years of age with metastatic TGCT (seminoma and non-seminoma) will be enrolled before starting first-line chemotherapy in several French hospitals. The primary (CRF) and secondary (cognitive/psychological/metabolic sequelae, HRQoL, etc.) outcomes and gut microbiota and relevant metabolites will be assessed at inclusion, during and at the end of the one-year intervention, and annually until 10 years since inclusion to assess long-term sequelae, more specifically CRF, cardiovascular toxicities, and second primary cancer occurrence in this population. DISCUSSION: This trial will provide comprehensive and novel insights into the effects of a long-term supervised PA program on CRF and other sequelae in metastatic TGCT patients receiving first-line chemotherapy. It will also contribute to understanding the potential role of the gut microbiota and its metabolites in mediating the effects of PA on these outcomes. The findings of this study will help the development of effective PA interventions to improve the health of TGCT survivors and may have implications for other cancer populations as well. TRIAL REGISTRATION: The study was registered on ClinicalTrials.gov (NCT05588700) on 20 Oct. 2022.

RÉSUMÉ

BACKGROUND: The pineal lesion affecting melatonin is a rare cause of central precocious puberty by decreasing the inhibition of hypothalamic-pituitary-gonadal axis. Germ cell tumor secreting human chorionic gonadotropin is a rare cause of peripheral puberty. CASE PRESENTATION: A 5.8-year-old male presented facial hair and phallic growth, deepened voice, and accelerated growth velocity for 6 months. The elevated human chorionic gonadotropin level with undetectable gonadotropin levels indicated peripheral precocious puberty. Brain imaging revealed a pineal mass and further pathology indicated the diagnosis of teratoma. During chemoradiotherapy with operation, the elevated human chorionic gonadotropin level reduced to normal range, while the levels of gonadotropins and testosterone increased. Subsequently, progressing precocious puberty was arrested with gonadotrophin-releasing hormone analog therapy. Previous cases of transition from peripheral precocious puberty to central precocious puberty were reviewed. The transitions were caused by the suddenly reduced feedback inhibition of sex steroid hormones on gonadotropin releasing hormone and gonadotropins. CONCLUSIONS: For patients with human chorionic gonadotropin-secreting tumors, gonadotropin levels increase prior to sex steroid decrease, seems a sign of melatonin-related central PP related to melatonin.

RÉSUMÉ

Intracranial germ cell tumors (iGCTs) are rare malignant neoplasms that mainly affect children and adolescents. The incidence, clinical presentation, and prognosis of iGCTs exhibit high heterogeneity. Previous studies have primarily focused on eliminating tumors, reducing tumor recurrence, and improving survival rates, while neglecting the impact of the tumors and their treatment on neuroendocrine function. Throughout the entire course of the disease, neuroendocrine dysfunction may occur and is frequently overlooked by oncologists, neurosurgeons, and radiologists. Endocrinologists, however, are more interested in this issue and have varying priorities at different stages of the disease. From onset to the diagnostic phase, most patients with iGCTs may present with symptoms related to impaired neuroendocrine function, or even experience these symptoms as their first indication of the condition. Particularly, a minority of patients with sellar/suprasellar lesions may exhibit typical imaging features and elevated tumor markers long after the onset of initial symptoms. This can further complicate the diagnosis process. During the peritumor treatment phase, the neuroendocrine function shows dynamic changes and needs to be evaluated dynamically. Once diabetes insipidus and dysfunction of the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axes occur, hormone replacement therapy should be administered promptly to ensure successful tumor treatment for the patient. Subsequently, during the long-term management phase after the completion of tumor treatment, the evaluation of growth and development as well as corresponding hormone replacement therapy are the most concerning and complex issues. Thus, this paper reviews the interest of endocrinologists in iGCTs at different stages.

RÉSUMÉ

Germ cell tumors (GCTs) are associated with pure gonadal dysgenesis or Swyer syndrome. Swyer syndrome usually presents with primary amenorrhea, streak ovaries, and mixed GCT. However, our patient presented with secondary amenorrhea, normal female external genitalia, and a mixed GCT. Constitutional karyotype was suggestive of 46,XY. Management comprised chemotherapy, followed by surgery. Histopathology was suggestive of dysgerminoma complicating a gonadoblastoma. The purpose of reporting this case is its rarity and the importance of diagnosing an XY karyotype, as the incidence of GCTs is higher in these patients.

RÉSUMÉ

Testicular mixed germ cell tumors (TMGCTs) are aggressive neoplasms that often have metastases at the time of diagnosis, primarily in the lungs, bones, and brain. Gastrointestinal metastases are rare, occurring in less than 5% of cases, while duodenal involvement is extremely rare, with only few reported cases. Furthermore, gastrointestinal bleeding is an atypical initial presentation of metastatic TMGCTs. Herein, we present a very rare case of upper gastrointestinal bleeding caused by a duodenal metastasis of a TMGCT in a 24-year-old man. The patient was admitted to our hospital due to abdominal pain and melena with a hemoglobin level of 52 g/L. He had no history of testicular swelling, or any other symptoms or signs of a testicular tumor. Upper gastrointestinal endoscopy revealed a duodenal tumor mass with irregular bleeding, and abdominal ultrasound and computed tomography showed a duodenal mass that infiltrate retroperitoneum. Emergency surgery was performed, and the histopathological findings of the resected specimen were consistent with TMGCT metastasis. Subsequently, a testicular tumor was confirmed and surgically removed; however, multiple metastatic deposits were observed in the lungs. Due to the patient's poor general condition, chemotherapy was not performed. The patient died 3 months after the initial diagnosis. This case suggests that, although duodenal metastatic TMGCTs are rare, they should be considered in the differential diagnosis of gastrointestinal bleeding in young male patients.

RÉSUMÉ

Electronic cigarette, or vaping, product use-associated lung injury (EVALI) is an increasingly recognized entity with the potential for severe pulmonary toxicity. We present the case of a young man first evaluated at a tertiary care center in the United States in 2019 with newly diagnosed testicular cancer with acute respiratory failure, which was initially attributed to possible metastatic disease but eventually determined to be related to EVALI. This case highlights the clinical features of EVALI, the potential diagnostic dilemma that can arise with EVALI when occurring in the setting of malignancy and the importance of inquiring about vaping use among patients with malignancy, especially in adolescents and young adults.

RÉSUMÉ

BACKGROUND: Both testicular germ cell tumours (TGCT) and neurodevelopmental disorders are associated with urogenital malformations. Few studies have investigated the association between psychiatric disorders and TGCT. We investigated whether history of any psychiatric or neurodevelopmental disorder is associated with increased risk or mortality of TGCT. METHOD: This is a nested case-control study including 6166 TGCT patients diagnosed during 1992-2014, individually matched for age and calendar period to 61,660 controls. We calculated odds ratios (ORs) for the association between type of psychiatric diagnoses and TGCT risk. Among the cases, we used a cohort design and calculated hazard ratios (HRs) of the association between psychiatric diagnose and all-cause and TGCT-specific death. RESULTS: History of a neurodevelopmental disorder (attention deficit hyperactivity disorder, autism spectrum disorder and intellectual disabilities) was associated with an increased risk of seminoma (OR: 1.54; 1.09-2.19). Seminoma patients with neurodevelopmental disorders were younger (34 versus 38 years, p = 0.004) and had more stage IV disease (5.4% versus 1.2%) than those without. Psychiatric history overall was not associated with TGCT. Patient history of any psychiatric disorder was associated with an increased all-cause and TGCT-specific death. CONCLUSIONS: We report an association between neurodevelopmental disorders and testicular seminoma, and an increased TGCT-specific mortality for TGCT patients with psychiatric disorders.

RÉSUMÉ

OBJECTIVES: Testicular germ cell tumours (TGCTs) are the most commonly diagnosed malignancy among active duty US military servicemen. Occupational risk factors may play a role in TGCT aetiology, although the evidence is inconclusive. The objective of our study was to investigate associations between military occupations and TGCT risk among US Air Force (USAF) servicemen. METHODS: This nested case-control study among active duty USAF servicemen obtained information on military occupations for 530 histologically confirmed TGCT cases diagnosed during 1990-2018 and 530 individually matched controls. We determined military occupations using Air Force Specialty Codes ascertained at two time points: at case diagnosis and at a time point on average 6 years earlier. We computed adjusted ORs and 95% CIs from conditional logistic regression models to evaluate associations between occupations and TGCT risk. RESULTS: The mean age at TGCT diagnosis was 30 years. Increased TGCT risk was observed for pilots (OR=2.84, 95% CI: 1.20-6.74) and servicemen with aircraft maintenance jobs (OR=1.85, 95% CI: 1.03-3.31) who held those jobs at both time points. Fighter pilots (n=18) and servicemen with firefighting jobs (n=18) at the time of case diagnosis had suggestively elevated TGCT odds (OR=2.73, 95% CI: 0.96-7.72 and OR=1.94, 95% CI: 0.72-5.20, respectively). CONCLUSIONS: In this matched, nested case-control study of young active duty USAF servicemen, we found that pilots and men with aircraft maintenance jobs had elevated TGCT risk. Further research is needed to elucidate specific occupational exposures underlying these associations.

RÉSUMÉ

ABSTRACT: Primary mediastinal germ cell tumors are uncommon tumors, of which the nonseminomatous type is more likely to metastasize than the seminomatous type. Primary mediastinal germ cell tumors may also present with superior vena cava obstruction. Here, we present this case of primary mediastinal germ cell tumor with superior vena cava obstruction causing dilatation of collaterals in dorsal intravertebral venous plexus, which strongly mimics sclerotic skeletal lesions/metastasis on a Contrast-enhanced CT scan and also appears FDG avid on PET scan. Herein, we can differentiate the two by just a simple review of plain CT scan image.

RÉSUMÉ

INTRODUCTION: The intention of this study was to evaluate the level of anxiety and depression of malignant ovarian germ cell (MOGCT) and sex cord stromal tumors (SCST) survivors and to identify possible alterable cofactors. METHODS: CORSETT was an observational, multicenter, mixed retrospective/prospective cohort study of the AGO Studygroup. Women who had been diagnosed with MOGCTs and SCSTs between 2001 and 2011 were asked to complete the Hospital Anxiety and Depression Scale (HADS) to evaluate distress. Predictors of distress (type of surgery, chemotherapy, time since diagnosis, recurrence, second tumor, pain) were investigated using multivariate linear regression analysis. RESULTS: 150 MOGCT and SCST patients with confirmed histological diagnosis completed the questionnaire median seven years after diagnosis. They had a HADS total score ≥ 13 indicating severe mental distress in 34% of cases. Patients after fertility-conserving surgery had lower probability of severe mental distress than those without fertility-conserving treatment (ß = - 3.1, p = 0.04). Pain was associated with the level of distress in uni- and multivariate analysis (coef 0.1, p < 0.01, coef. Beta 0.5). DISCUSSION: Severe mental distress was frequent in patients with MOGCT and SCST and the level of pain was associated with the level of distress. Fertility conserving therapy, however, was associated with less mental distress. Screening and treatment of pain and depression is required to improve mental well-being in survivors of MOGCT and SCST.
