A 69-year-old man was referred to our hospital with the chief complaint of a painless right scrotal swelling gradually increasing in size during the past 10 years. Testicular tumor markers were within the normal range. Ultrasonography showed an intrascrotal homogeneous mass. Computed tomography and magnetic resonance imaging revealed an inguinal mass, which mainly consisted of fat signal area and partially well enhanced in vascular density. Pre-surgical diagnosis was liposarcoma of spermatic cord estimated by radiographic examination and resection of the right intrascrotal tumor with high inguinal orchitectomy was performed...

We reported two cases of hyperthyroidism that developed during induction chemotherapy for advanced germ cell tumors with high serum human chorionic gonadotropin (hCG) levels. Case 1 : An 18-year-old man with mediastinal choriocarcinoma complained of tachycardia and tremor. His pretreatment serum hCG level was 1.37 million mIU/ml. The free thyroxine (fT4) level measured on day 2 of the first course of bleomycin, etoposide and cisplatin (BEP) was elevated to 7.8 ng/dl (<1.7 ng/dl), whereasthe thyroidstimulating hormone (TSH) level was undetectable...

Tripartite motif 44 (TRIM44) is one of the TRIM family proteins that are involved in ubiquitination and degradation of target proteins by modulating E3 ubiquitin ligases. TRIM44 overexpression has been observed in various cancers. However, its association with testicular germ cell tumor (TGCT) is unknown. We aimed to investigate the clinical significance of TRIM44 and its function in TGCT. High expression of TRIM44 was significantly associated with alpha feto-protein levels, clinical stage, nonseminomatous germ cell tumor (NSGCT), and cancer-specific survival (P = 0...

Suicide risk in adult cancer patients is found to be elevated, but limited information exists regarding risks of suicide and non-suicidal violent deaths when diagnosed with cancer in young age. We investigate suicide and violent deaths in a national cohort including individuals diagnosed with cancer before age 25. Through the linkage of different national registries (Cancer Registry of Norway, Norwegian Causes of Death Registry, and the National Registry) a cohort of all live births in Norway during 1965-1985 was defined and followed up through 2008...

Chemotherapeutic drug-induced apoptosis is enhanced by gap junction intercellular communication (GJIC) in a variety of tumor cells. Oxaliplatin and gefitinib are the most widely used chemotherapeutic drugs. However, the synergistic influence remains unknown in testicular cancer chemotherapy. The aim of the present study was to investigate the apoptosis induced by oxaliplatin combined with gefitinib and the potential mechanisms in I-10 testicular cancer cells. The results showed that gefitinib significantly enhanced oxaliplatin-induced apoptosis...

Undescended testicle is the most common congenital anomaly among males. Testicular tumor develops in 3-5% of the boys with a complaint of undescended testicle. The clinical presentation of malignant intra-abdominal testicular tumors ranges from asymptomatic cases to acute abdomen. In this study, we present a child with testicular tumor rupture which is observed very rarely. A 16-year-old boy presented 24 hours after the sudden onset of right lower quadrant pain, nausea, vomiting and fever. On physical examination, extensive tenderness in the abdomen and abdominal guarding were found...

Childhood malignant testicle tumors are very rare. In the literature to date, it has been reported that there are only 24 cavernous hemangioma cases existing in English literature. In this study, we discuss a testicular mass case which was diagnosed as cavernous hemangioma. The patient, who followed for left multicystic dysplastic kidney since his birth, was admitted to our clinic with complaints of left testicular mass and pain at 1-year of age. Histopathological investigation revealed cavernous hemagioma...

BACKGROUND: Primary treatment of choice for advanced germ cell tumors is 3 to 4 cycles of combination PEB chemotherapy. Although most patients treated for advanced germ cell tumors (GCT) will be cured, approximately 30% will fail to achieve a durable complete response (CR). Thrombocytosis has been found to be related with significantly shorter survival in many cancers. However, its role in testicular cancer patients has not been studied previously. The objective of this study was to investigate the relationship between thrombocytosis and chemotherapy response in patients with metastatic testicular cancer...

Due to its palindromic setup, AZFc (Azoospermia Factor c) region of chromosome Y is one of the most unstable regions of the human genome. It contains eight gene families expressed mainly in the testes. Several types of rearrangement resulting in changes in the cumulative copy number of the gene families were reported to be associated with diseases such as male infertility and testicular germ cell tumors. The best studied AZFc rearrangement is gr/gr deletion. Its carriers show widespread phenotypic variation from azoospermia to normospermia...

Development of a malignant germ cell tumor, i.e., germ cell cancer (GCC) in individuals with disorders of sex development (DSD) depends on a number of (epi-)genetic factors related to early gonadal- and germ cell development, possibly related to genetic susceptibility. Fetal development of germ cells is orchestrated by strict processes involving specification, migration and the development of a proper gonadal niche. In this review we will discuss the early (epi-)genetic events in normal and aberrant germ cell and gonadal development...

We report a histologically pure stage 1 seminoma with an elevated human chorionic gonadotropin (hCG). A 38 year-old man was referred for the evaluation of the left testicular swelling. He showed an elevated serum hCG level of 25,265 mIU/ml with normal a fetoprotein and lactate dehydrogenase. Imaging showed heterogeneous tumor without any metastatic lesions. We conducted 4 courses of chemotherapy before detecting hCG nadir. The final pathological report showed pure seminoma with syncytiotrophoblastic cells but no choriocarcinoma components...

INTRODUCTION: Testicular cancer is one of the most frequent in young men and its incidence is increasing in recent years because of incidental finding during routine ultrasound exams. Adenomatous hyperplasia of the rete testis is one of the benign and rare pathological types incidentally detected and very few cases are described in the literature. CASE REPORT: A 40 years old man come to our attention for a balanoposthitis without testicular pain. During andrological examination we performed palpation of the testes and we noticed a palpable nodule of hard consistency in the left testicle...

We recently demonstrated that the orphan nuclear receptor testicular receptor 4 (TR4) is a potent regulator of corticotroph tumor growth and hormone secretion. The Ras/Raf/MEK/ERK pathway is commonly overactivated in human tumors and we have demonstrated that corticotroph tumor TR4 is activated by ERK1/2-mediated phosphorylation. We evaluated effects of MEK-162, a selective, non-ATP-competitive allosteric inhibitor of MEK1/2, on murine and human in vitro and in vivo corticotroph tumor proliferation and adrenocorticotrophic hormone (ACTH) secretion...

Tofacitinib is an oral Janus kinase (JAK) inhibitor for the treatment of rheumatoid arthritis. Tofacitinib preferentially inhibits receptor signaling through JAK3 and JAK1, relative to JAK2. In the 2-year rat carcinogenicity study, there were tofacitinib, dose-related increases in the incidences of testicular Leydig cell hyperplasia and benign adenomas in male rats, and decreased incidences of mammary tumors and duct dilatation/galactocele in female rats. Such findings in rats are typical of agents, such as dopamine agonists, which decrease prolactin (PRL) activity...

INTRODUCTION: Prostate carcinoma is the most frequently diagnosed carcinoma in the male population. The most typical places of the metastases are pelvic lymphatic glands, bones and lungs, and very rarely it metastasizes into a testis. The prognostic importance of testicular metastasis of prostate cancer is not yet well-known, due to a very few published cases. According to the known facts, it is certain that a metastasis of the prostate carcinoma into a testis is a sign of an advanced disease...

Despite the fact that testicular germ cell tumors (TGCTs) are one of the most chemosensitive solid tumors, a small proportion of patients fail to be cured following cisplatin-based first line chemotherapy. Upregulation of carbonic anhydrase IX (CA IX) in various solid tumors is associated with poor outcome. The current prospective study investigated the prognostic value of serum CA IX level in TGCTs. In total, 83 patients (16 non-metastatic following orchiectomy with no evidence of disease, 57 metastatic chemotherapy-naïve and 10 metastatic relapsed chemotherapy-pretreated) starting adjuvant and/or new line of chemotherapy and 35 healthy controls were enrolled in the study...

The clinical history and imaging and pathologic findings in 4 patients with bilateral synchronous testicular tumors of dissimilar histologic types were reviewed. All patients had a large scrotal mass on one side and a smaller nodule on the other one. The appearances of each pair of lesions were different enough to suggest that they could possibly be of different histologic types. The most important role of imaging, however, was its capability to guide the surgical approach to these patients: in 1 case, the smallest lesion was recognized as an epidermoid cyst; in 2 others a conservative approach was deemed possible, given the lesions' small volumes and peripheral locations...
