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)...

Background. Somatic type malignancy (STM) occurs in 2% of all germ cell tumours (GCTs). The prognosis is unfavourable and the origin is poorly understood. Pathogenetic hypotheses involve direct transformation of teratoma, origin from totipotent cancer cells, or derivation from yolk sac tumour elements. Case Presentation. A 31-year-old patient was cured from testicular seminoma clinical stage IIc by orchiectomy and cisplatin-based chemotherapy. Nine years later, he experienced a late relapse with a mass sized 5 × 6 cm located at the former metastatic site...

CONTEXT: - Testicular germ cell tumors with lymphovascular invasion (LVI) are staged pT2, and those with spermatic cord involvement are staged pT3. OBJECTIVE: - To study the clinical significance of LVI within the spermatic cord without direct involvement of the cord soft tissues. DESIGN: - A retrospective, multi-institutional review was performed on testicular GCTs with spermatic cord LVI in the absence of cord soft tissue invasion. RESULTS: - Forty-four germ cell tumors had LVI in the spermatic cord without soft tissue invasion; 37 of 44 patients (84%) had nonseminomatous germ cell tumors (NSGCT), and 7 (16%) had pure seminomas...

It is well-known that cardiovascular disease is the most common cause of sudden unexpected death, especially in the young. However complete postmortem investigation performed by qualified forensic pathologists is crucial in establishing the exact cause and manner of death. Sudden death caused by a cardiac tamponade occurring secondarily to a primary mediastinal tumor is extremely unusual. An autopsy on a 25-year-old man who died unexpectedly discovered a massive hemopericardium in association with an anterosuperior mediastinal mass...

Chronic lymphedema predisposes to develop malignant cutaneous tumors, including angiosarcoma, Kaposi's sarcoma and B cell lymphoma. T cell malignancy has rarely been associated with chronic lymph stasis. Here we report a case of primary cutaneous anaplastic large cell lymphoma (pcALCL) with lymphatic spread associated with chronic lymphedema. The patient is a 56-year-old man who received orchiectomy and right inguinal lymphadenectomy for malignant seminoma 10 years ago, which led to prominent lymphedema of the right leg...

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...

Objective To evaluate the immunohistochemical staining pattern of caudal type homeobox 2 (CDX2) protein in germ cell tumours (GCTs) of the testis. Methods This study reassessed archival tissue samples collected from patients diagnosed with primary and metastatic testicular GCTs for CDX2 immunoreactivity using standard immunohistochemical techniques. Positive nuclear immunostaining was evaluated with regard to both the staining intensity and the extent of the staining. Results Tissue sections from primary and metastatic testicular GCTs ( n = 104), germ cell neoplasia in situ (GCNis) ( n = 5) and benign testicles ( n = 15) were analysed...

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...

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...

The development of testes occurs in the abdomen during fetal life, after which they migrate into the scrotal sacs during the third trimester. During their descent, they may get arrested anywhere along the tract. Risk of testicular cancer is higher in patients with undescended testes, abdominal testis being more prone than inguinal. Seminoma is the commonest cancer in undescended testis. However, synchronous seminoma involving bilateral cryptorchid testis is rare. Present case is uncommon due to synchronous involvement of abdominopelvic and inguinal testes in extended age...
