BACKGROUND: Most patients with testicular cancer are infertile; thus, the preservation of the sperm after surgery is an important factor to consider. We report two cases of bilateral testicular cancer in patients who underwent bilateral higher orchiectomy and simultaneous testicular sperm extraction. CASE PRESENTATION: Two Asian-Japanese men were referred to our hospital with bilateral testicular tumors. Both of the patients were preoperatively diagnosed with azoospermia and requested testicular sperm extraction at the time of higher orchiectomy...

Platinum-based chemotherapy is usually curative for patients with testicular germ cell tumors (TGCT), but a subset of patients experience disease progression and poor clinical outcomes. Here, we tested whether immune profiling of TGCT could identify novel prognostic markers and therapeutic targets for this patient cohort. We obtained primary and metastatic TGCT samples from one center. We performed immune profiling using multiplexed fluorescence immunohistochemistry (FIHC) for T-cell subsets and immune checkpoints, and targeted gene expression profiling (Nanostring nCounter Immune panel)...

Histologically pure seminoma with elevated alpha-fetoprotein (AFP), so-called AFP-positive seminoma, is rare. It is recommended that patients with AFP-positive seminoma be managed as non-seminoma, but the clinical features and prognosis of this disease are not fully understood. In this study, we retrospectively analyzed 6 cases of metastatic AFP-positive seminoma at Tsukuba University Hospital (TUH). AFP was elevated before induction chemotherapy in 4 patients with an average of 1,372 ng/ml. In the remaining 2 patients, AFP became elevated during or after induction chemotherapy...

The incidence of metastases to the neck in testicular cancer is 4-15%, and in 5% of these cases the metastasis is the only symptom. We present a 57-year-old asymptomatic male, who had previously been treated for colon cancer. A routine PET-CT showed enlarged lymph nodes in the retroperitoneum and at the neck. A core needle biopsy from the lymph node at the neck contained malignant cells, but not from colon cancer. The lymph node was extirpated, and pathological analysis proved it to be a metastasis from a testicular seminoma...

A case of a 45,X/46,XY boy with gonadal dysgenesis is presented. The patient showed hypospadias and right undescended testis. He underwent underwent repair surgery for hypospadias, right orchidopexy, and bilateral testicular biopsy. Testicular biopsy revealed no malignant finding. He was followed-up annually by scrotum palpation. When the patient grew up to 24 years old, he was diagnosed to have right testicular tumor. High orchiectomy revealed pT1 seminoma. The management of undescended testis in men with gonadal dysgenesis and disordered sexual development is discussed...

Earlier revisions of the WHO classification of testicular tumors, which was originally published in 1977, contained only minor additions. In the WHO 2016 classification, in contrast, germ cell tumors are split into two major groups based on their distinct pathohistogenesis, i. e., those which derive from an in situ forerunner lesion and those which do not. The latter category includes prepubertal yolk sac tumors and teratomas, as well as spermatocytic seminoma. The classification of yolk sac tumors and teratomas as arising before or after puberty is also of prognostic value...

 Background: The Primitive Extratesticular Seminoma is a very rare condition and represents 3% of germ cell tumors; it is an indeterminate origin disease, whose diagnosis is often complicated by a nonspecific and highly variable clinical finding. CASE PRESENTATION: A caucasian 55 years old male, non-smoker, arrived to our centre with cough, severe respiratory distress and dysphagia, in a context of the superior vena cava syndrome. A Computed Tomography was performed, which shows the presence of a mediastinal anterior mass with aorto-pulmonary window and left paracardiac invasion...

Human testis, gonocytes, and adult germ cells mainly express estrogen receptor beta, and estrogen receptor beta loss is associated with advanced tumor stage; however, the molecular mechanisms of estrogen receptor beta-protective effects are still to be defined. Herein, we provide evidence that in human seminoma TCam-2 cells, E2 through estrogen receptor beta upregulates the mitochondrial deacetylase sirtuin-3 at protein and messenger RNA levels. Specifically, E2 increases sirtuin-3 expression through a transcriptional mechanism due to the occupancy of sirtuin-3 promoter by estrogen receptor beta, together with the transcription factor Sp1 as evidenced by Chip reChIp assay...

Testicular germ cell tumors (TGCTs) represent a highly curable malignancy, however a small proportion of patients fails to be cured with cisplatin-based chemotherapy. Carbonic anhydrase IX (CA IX) is upregulated by hypoxia in several cancer types and correlates with a poor prognosis. The present translational study evaluated expression and prognostic value of CA IX in TGCTs. Surgical specimens from 228 patients with TGCTs were processed by the tissue microarray method and subjected to immunohistochemistry with the M75 monoclonal antibody...

Primary mediastinal seminoma is a rare extragonadal germ cell tumour that mainly occurs in males. The present study reports the case of a 27-year-old woman that presented with superior vena cava syndrome and a large mass in the mediastinum, which was diagnosed as primary female mediastinal seminoma. The patient received 6 cycles of cisplatin-based chemotherapy [4 cycles BEP chemotherapy (120 mg cisplatin, 0.45 g etoposide and 60 mg bleomycin, once every 3 weeks); 2 cycles IEP chemotherapy (120 mg cisplatin, 100 mg epirubicin and 6 g ifosfamide, once every 3 weeks)] and the patient showed an increase in the size of the mediastinal mass and hydropericardium, indicating a resistance to chemotherapy...

Spermatocytic tumor, formerly known as spermatocytic seminoma, is an uncommon testicular neoplasm which is a distinct clinicopathologic entity from classic seminoma. These tumors are not associated with germ cell neoplasia in situ, other germ cell tumors, or isochromosome 12p. Although typically, these tumors have an excellent prognosis occasional cases are associated with sarcoma and have a very poor prognosis. We present a case of spermatocytic tumor with sarcoma showing a chondrosarcomatous component, discuss the pathologic findings and differential diagnosis and provide follow-up information...

Synchronous bilateral testis cancer (SBTC) is a rare event. It represents only 0.5-1% of all new cases of testicular cancer. Patients with this disease require careful management for psychological, oncological, and medical problems. We performed a PubMed search for all series that reported SBTC. We considered only articles in English, reporting on more than three cases. We also performed an analysis of the reported evidence regarding testosterone replacement and surgical treatment. We found 10 studies satisfying inclusion criteria for a total of 73 patients...

Surgical resection of metastases represents an integral part of curative management in patients with testicular germ cell tumors (GCT). Primary nerve-sparing retroperitoneal lymph node dissection (nsRPLND) for low volume metastases in clinical stages I-IIB has to be differentiated from the more complex and more extensive postchemotherapeutic procedures. In Europe, primary nerve-sparing retroperitoneal lymph node dissection (nsRPLND) for clinical stage I nonseminomatous GCT (NSGCT) plays a subordinate. In clinical stage IIA/B, nsRPLND is indicated for patients with marker-negative metastases in whom cure rates of about 65% can be achieved with surgery alone...

Testicular cancer is a relatively rare tumor type, accounting for approximately 1% of all cancers in men. However, among men aged between 15 and 40 years, testicular cancer is the most commonly diagnosed malignancy. Testicular germ cell tumors (TGCTs) are classified as seminoma and non-seminoma. The RAS oncogene controls several cellular functions, including cell proliferation, apoptosis, migration, and differentiation. Thus, RAS signaling is important for normal germ cell development. Mutations of the Kirsten RAS (K-RAS) gene are present in over 20% of all cancers...

PURPOSE: Testicular germ cell tumors (TGCTs) are nearly universally curable malignancies. Nevertheless, standard cisplatin-based chemotherapy is not curative in a small subgroup of patients. Previously, we showed that PD-L1 overexpression is associated with worse prognosis in TGCTs, while tumor infiltrating lymphocytes (TILs) are prognostic in different types of cancer. This study aimed to evaluate the prognostic value of PD-1 and PD-L1 expressing TILs in TGCTs. RESULTS: PD-L1 positive TILs were found significantly more often in seminomas (95...

CASE: A 39 year-old man presented to the emergency department complaining of a cough of 2 months in duration. He also complained of weight loss of 20 pounds in two months and night sweats over the same period. An x-ray of the chest was performed and revealed innumerable lung nodules and masses. Computed tomography of the chest and abdomen were subsequently performed which confirmed the masses, but imaging did not reveal an obvious primary source. A testicular exam was performed but no obvious abnormalities were noted...

BACKGROUND: Mediastinal thymic seminomas are rare male germ cell tumors with extragonadal origin that appear predominately with a cystic appearance. CASE PRESENTATION: A 22-year-old male was referred to our department for further investigation of a mediastinal mass discovered incidentally during routine chest X-ray. The patient has denied any symptoms including dyspnea, chest pain, cough, fever, dysphagia, hemoptysis, weight loss, and weakness. His past medical history was remarkable for orchitis, for which he had undergone a bilateral testicular biopsy, without the latter however, indicating the presence of a germ cell tumor or a premalignant lesion...

BACKGROUND: Nuclear protein in testis (NUT) midline carcinoma is a rarely diagnosed and potentially under-recognized type of squamous carcinoma that is considered one of the most aggressive human solid tumors. Alpha-fetoprotein elevation has been associated with chronic liver diseases and a limited number of cancers. In particular, in presence of a mediastinal mass in a young man, alpha-fetoprotein elevation is considered nearly pathognomonic of a non-seminoma germ-cell tumor. CASE PRESENTATION: A 22-year old man without any comorbidity was diagnosed with a large mediastinal mass with skeletal and lymph node metastases...

BACKGROUND: Granulomatous slack skin (GSS) is an extremely rare subtype of T-cell lymphoma, a variant of mycosis fungoides (MF). Herein, we describe the first reported case of GSS associated with metastatic testicular seminoma. PATIENTS AND METHODS: A 28-year-old male patient presented with circumscribed erythematous loose skin masses, especially in the body folds and which had been relapsing for 4years. Skin biopsy showed a loss of elastic fibers and an atypical granulomatous T-cell infiltrate with epidermotropism, enabling a diagnosis of GSS to be made...

INTRODUCTION: Approximately 95% of all testicular cancers are testicular germ cell tumors (GCTTs), represented by seminoma and nonseminoma germ cell testicular cancer. There is a hypothesis that the formation of GCTTs begins in early embryogenesis being a part of testicular dysgenesis syndrome (TDS). AIM: To determine the role of genetic factors in the development of GCTTs. MATERIALS AND METHODS: We studied the frequency of alleles and genotypes KITLG (rs995030, rs1508595), SPRY4 (rs4624820, rs6897876) and BAK1 (rs210138) in 97 fertile men (control), and 73 patients with GCTTs (34 seminoma and 39 nonseminoma)...
