    Recurrence of hypercortisolism in patients after bilateral adrenalectomy for Cushing disease is extremely rare. We present a 27-year-old man who previously underwent bilateral adrenalectomy for Cushing disease with complete clinical resolution. Cushingoid features recurred 12 years later, with bilateral testicular enlargement. Hormonal tests confirmed adrenocorticotropic hormone (ACTH)-dependent Cushing disease. Surgical resection of the testicular tumors led to clinical and biochemical remission. Gene expression analysis of the tumor tissue by quantitative polymerase chain reaction showed high expression of all key steroidogenic enzymes. Adrenocortical-specific genes were 5.1 × 105 (CYP11B1), 1.8 × 102 (CYP11B2), and 6.3 × 104 (MC2R) times higher than nonsteroidogenic fibroblast control. This correlated with urine steroid metabolome profiling showing 2 fivefold increases in the excretion of the metabolites of 11-deoxycortisol, 21-deoxycortisol, and total glucocorticoids. Leydig-specific genes were 4.3 × 101 (LHCGR) and 9.3 × 100 (HSD17B3) times higher than control, and urinary steroid profiling showed twofold increased excretion of the major androgen metabolites androsterone and etiocholanolone. These distinctly increased steroid metabolites were suppressed by dexamethasone but unresponsive to human chorionic gonadotropin stimulation, supporting the role of ACTH, but not luteinizing hormone, in regulating tumor-specific steroid excess. We report bilateral testicular tumors occurring in a patient with recurrent Cushing disease 12 years after bilateral adrenalectomy. Using mRNA expression analysis and steroid metabolome profiling, the tumors demonstrated both adrenocortical and gonadal steroidogenic properties, similar to testicular adrenal rest tumors found in patients with congenital adrenal hyperplasia, suggesting the presence of pluripotent cells even in patients without congenital adrenal hyperplasia.

    Full Text Available Objectives : Intratubular germ cell neoplasia (ITGCN is the precursor lesion for invasive testicular germ cell tumors (TGCTs of adolescents and young adults. The rising incidence of these tumors has prompted a rigorous investigation of the etiology, diagnosis and management of ITGCN. Bilateral testicular cancer is closely linked with ITGCN, as patients with unilateral testicular cancer are at the highest risk for a future malignancy in the contralateral testicle. Methods : A literature review directed at ITGCN and bilateral testis cancer was performed using the Medline/PubMed database. Our review focused on the pathogenesis, risk factors, diagnosis and treatment regimens utilized. Results : Major advances have been made in the understanding of ITGCN over the past 30 years. There is evidence that TGCTs arise from ITGCN, ITGCN is closely related to fetal gonocytes, and that events in pre- and perinatal period may result in abnormal persistence of fetal gonocytes leading to ITGCN and subsequent TGCT. Controversy exists regarding the need to biopsy men at increased risk of TGCT, as well as the best approach to managing patients with known ITGCN. Bilateral testicular cancer has excellent outcomes in the current era of platinum-based chemotherapy. Conclusion : The optimal management of patients at risk for ITGCN and future TGCT is still a matter of debate. Individualization of management, including biopsy and treatment, should be based on risk factors for TGCT, compliance with potential surveillance, and patient preferences particularly with regard to fertility.

    Intratubular germ cell neoplasia, the precursor of testicular germ cell tumors (TGCTs), is hypothesized to arise during embryogenesis from developmentally arrested primordial germ cells (PGCs) or gonocytes. In early embryonal life, the PGCs migrate from the yolk sac to the dorsal body wall where the cell population separates before colonizing the genital ridges. However, whether the malignant transformation takes place before or after this separation is controversial. We have explored the somatic exome-wide mutational spectra of bilateral TGCT to provide novel insight into the in utero critical time frame of malignant transformation and TGCT pathogenesis. Exome sequencing was performed in five patients with bilateral TGCT (eight tumors), of these three patients in whom both tumors were available (six tumors) and two patients each with only one available tumor (two tumors). Selected loci were explored by Sanger sequencing in 71 patients with bilateral TGCT. From the exome-wide mutational spectra, no identical mutations in any of the three bilateral tumor pairs were identified. Exome sequencing of all eight tumors revealed 87 somatic non-synonymous mutations (median 10 per tumor; range 5-21), some in already known cancer genes such as CIITA, NEB, platelet-derived growth factor receptor α (PDGFRA), and WHSC1. SUPT6H was found recurrently mutated in two tumors. We suggest independent development lineages of bilateral TGCT. Thus, malignant transformation into intratubular germ cell neoplasia is likely to occur after the migration of PGCs. We reveal possible drivers of TGCT pathogenesis, such as mutated PDGFRA, potentially with therapeutic implications for TGCT patients. Copyright © 2014 Neoplasia Press, Inc. Published by Elsevier Inc.

    Inactivating germline mutations in phosphodiesterase 11A (PDE11A) have been implicated in adrenal tumor susceptibility. PDE11A is highly-expressed in endocrine steroidogenic tissues, especially the testis, and mice with inactivated Pde11a exhibit male infertility, a known testicular germ cell tumor (TGCT) risk factor. We sequenced the PDE11A gene-coding region in 95 patients with TGCT from 64 unrelated kindreds. We identified 8 non-synonymous substitutions in 20 patients from 15 families: four (R52T; F258Y; G291R; V820M) were newly-recognized, three (R804H; R867G; M878V) were functional variants previously implicated in adrenal tumor predisposition, and one (Y727C) was a known polymorphism. We compared the frequency of these variants in our patients to unrelated controls that had been screened and found negative for any endocrine diseases: only the two previously-reported variants, R804H and R867G, known to be frequent in general population, were detected in these controls. The frequency of all PDE11A-gene variants (combined) was significantly higher among patients with TGCT (P=0.0002), present in 19% of the families of our cohort. Most variants were detected in the general population, but functional studies showed that all these mutations reduced PDE activity, and that PDE11A protein expression was decreased (or absent) in TGCT samples from carriers. This is the first demonstration of a PDE gene’s involvement in TGCT, although the cAMP signaling pathway has been investigated extensively in other reproductive organs and their diseases. In conclusion, we report that PDE11A-inactivating sequence variants may modify the risk of familial and bilateral TGCT. PMID:19549888

  8. A Case of Bilateral Testicular Tumors Subsequently Diagnosed as Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency

    Full Text Available 21-hydroxylase deficiency (21-OHD caused congenital adrenal hyperplasia (CAH is a group of autosomal recessive genetic disorders resulting from mutations in genes involved with cortisol (CO synthesis in the adrenal glands. Testicular adrenal rest tumors (TARTs are rarely the presenting symptoms of CAH. Here, we describe a case of simple virilizing CAH with TARTs, in a 15-year-old boy. The patient showed physical signs of precocious puberty. The levels of blood adrenocorticotropic hormone (ACTH, urinary 17-ketone steroids (17-KS, dehydroepiandrosterone sulfate (DHEA-S, and serum progesterone (PRGE were elevated, whereas those of follicle-stimulating hormone (FSH, luteinizing hormone (LH, and CO were reduced. Computed tomography (CT of the adrenal glands and magnetic resonance imaging (MRI of the testes showed a soft tissue density (more pronounced on the right side and an irregularly swollen mass (more pronounced on the left side, respectively. Pathological examination of a specimen of the mass indicated polygonal/circular eosinophilic cytoplasm, cord-like arrangement of interstitial cells, and lipid pigment in the cytoplasm. Immunohistochemistry results precluded a diagnosis of Leydig cell tumors. DNA sequencing revealed a hackneyed homozygous mutation, I2g, on intron 2 of the CYP21A2 gene. The patient’s symptoms improved after a three-month of dexamethasone therapy. Recent radiographic data showed reduced hyperplastic adrenal nodules and testicular tumors. A diagnosis of TART should be considered and prioritized in CAH patients with testicular tumors. Replacement therapy using a sufficient amount of dexamethasone in this case helps combat TART.

    Intratubular germ cell neoplasia (ITGCN) is a precursor lesion for testicular germ cell tumors, most of which are early stage. ITGCN is also associated with testicular cancer or ITGCN in the contralateral testis, leading to a risk of bilateral testicular malignancy. Testicular biopsy detects most cases, and orchiectomy is the treatment of choice in patients with unilateral ITGCN. Low-dose radiation therapy is recommended in patients with bilateral ITGCN or ITGCN in the solitary testis, but the long-term risks of infertility and hypogonadism need to be discussed with the patient. Rare histologies of primary testicular cancer are also discussed. Copyright © 2015 Elsevier Inc. All rights reserved.

    Introduction: The patients with testicular germ cell tumors (TGT) present in the contralateral tumor development in approximately 3% of the cases. A small subset presenting with synchronous bilateral tumors (TBS). Case report: Patient is a 41-year study of infertility in who have performed bilateral testicular biopsies. Using ultrasound bilateral testicular nodules were diagnosed predominantly right. It performs a bilateral orchiectomy evidencing bilateral pure classic seminoma (T1 and T4). Staging the regional nodal involvement and distance rule and visceral with normal tumor markers. Receive adjuvant radiotherapy (3060 cGy) including inguinal lymph node chains, and pelvic and lumbo-aortic remaining free of disease at 33 months after surgery. Discussion: 85% of all bilateral TGT metachronous are presented as 15% synchronously. TBS represent less than 1% of the most representative series. In most cases they are seminomas and have been associated with infertility and history Family suggestive of genetic predisposition. Bilateral orchiectomy is local treatment of choice and subsequent planned strategy is according the loco-regional extension stressing the importance of hormone replacement and psychological support. Conclusions: In patients with a family history suggestive or infertile should be evaluated for TBS, especially if it carries a seminoma. the bilateral orchiectomy is local treatment of choice. We found no evidence seminomatous TBS have a worse prognosis compared with patients with unilateral or bilateral metachronous tumors of similar size lesional

    Twenty children with bilateral Wilms' tumor were presented to the Children's Hospital Medical Center and Children's Cancer Research Foundation, Sidney Farber Cancer Institute, and Joint Center for Radiation Therapy (CHMC-CCRF, SFCI, JCRT) from January 1, 1956 to December 31, 1976. Of these 20, 16 had simultaneous and 4 had metachronous disease on presentation. All patients were treated with surgery, radiation and chemotherapy. Of the 16 patients with simultaneous disease, 10 (63%) are alive and free of disease 12+ to 175+ months post diagnosis and treatment, with median follow-up of 121 months. There were no long-term survivors in the metachronous group; all were dead of disease within 21 months from initial presentation of original tumor. With these data we relate prognosis to extent of disease and discuss a general approach to the management of bilateral Wilms' tumor

    Recently, the treatment for testicular tumor has improved. Preservation of testicular function in the treatment of testicular tumor is important, because the majority of the patients are young. We investigated the testicular function of patients with testicular tumor before, during and after treatment. As a part of this study, the fertility of patients with testicular tumor before and after treatment was evaluated. 1. Fourteen of 78 married patients (18 %) showed sterility for two or more years before treatment. 2. When semen was examined in 31 patients before treatment, only seven patients (23 %) showed normal sperm counts of more than 40 x 10 6 /ml, and 19 (61.3 %) showed oligospermia or azoospermia with sperm counts of less than 10 x 10 6 /ml. 3. Of 20 patients who underwent retroperitoneal lymphnode dissection, 15 developed ejaculation deficiency. Four other patients also developed ejaculation deficiency but recovered, and three of them rendered their wives pregnant. 4. Of 23 patients given radiotherapy, nine produced children both before and after treatment, nine produced children before treatment but showed sterility after treatment, and five showed sterility both before and after treatment. 5. Examination of semen was performed in 17 patients given radiotherapy and in five given chemotherapy. Many patients developed oligospermia or azoospermia after the treatments, but revealed a tendency to recover with time. Based on the results mentioned above, it is inferred that the ability to produce sperm in patients with testicular tumor after treatment decreases but the decrease tends to recover to normal with time.

    Full Text Available A 51-year-old man with type 2 diabetes mellitus and chronic obstructive pulmonary disease presented to the emergency room with increasing bilateral leg pain, rash, and scrotal swelling with pain. Skin biopsy from his thigh revealed IgA-associated vasculitis. Due to hematuria, a renal biopsy was performed and showed an IgA glomerulonephritis with focal fibrinoid necrosis and neutrophil accumulation. Bilateral orchiectomies were performed in two separate procedures ten and thirteen days after the renal biopsy, as a result of uncontrolled abscess formation in testicles. Microscopically, both testicles revealed large abscess formation destroying almost the entire testicular parenchyma without tumor cells. Spermatic cord margins were further scrutinized microscopically to show bilateral vasculitis in many small size vessels, confirmed by positive endothelial staining for IgA. Some of the affected arteries revealed central organizing thrombi with recanalization features, highly suggestive of vasculitis-associated thrombi formation, resulting in testicular ischemic infarction and abscess formation. We conclude that this adult patient developed a severe form of Henoch-Schönlein purpura, with vasculitis affecting multiple organs, including the most serious and unusual complication of bilateral testicular infarction.

    Full Text Available Congenital adrenal hyperplasia (CAH patients with testicular adrenal rest tumors (TARTs with testicular enlargement present a serious diagnostic challenge. According to the data TARTs are usually benign. They are rare, resulting in paucity in the medical literature regarding their pathological features. We report a case of bilateral synchronous mass-forming TARTs with marked cytological and nuclear atypia misinterpreted as malignant testicular tumors in a 40-years-old man with CAH and CT and MRI data for pheochromocytoma of the right adrenal gland and paraaortal and paracaval lymphadenomegaly. He was previously diagnosed with adrenal cortical carcinoma of the left adrenal gland.

    In the past 20 years, the incidence of prostate cancer has risen rapidly. It has been ranked as the third most common malignant tumor of the male genitourinary system. Testicular metastasis is uncommon in prostate cancer. Most cases are incidentally found in the treatment of prostate cancer with orchiectomy. Therefore, we believed it was necessary to report the case of our patient with this disease. We present a case of a 69-year-old Han Chinese man with a high total prostate-specific antigen level. A transrectal ultrasound-guided prostate biopsy was performed. A pathology report showed prostate cancer tissue with a Gleason score of 4 + 4 = 8/10. Imaging findings suggested that the prostate cancer tissue involved bilateral seminal vesicles and multiple bones. Next, radioactive seed implantation was carried out, and endocrine therapy was continued after the operation. Then enlargement of the left scrotum was found along with a total prostate-specific antigen level of 19.21 ng/ml. Computed tomography of the middle abdomen and pelvic cavity revealed 2.0 × 1.3-cm lesions of the left testis. The patient underwent a left testicular high resection and right orchiectomy. The postoperative pathology report showed metastatic prostate cancer cells in the left testis. Testicular metastasis of prostate cancer is rare. Therefore, a testicular physical examination is necessary for patients without relapse to avoid a missed diagnosis. Testicular metastasis should be treated according to the principle of treatment for advanced prostate adenocarcinoma if testicular metastasis of prostate adenocarcinoma is detected.

    In this study the author reports about classification, clinical experience, therapy and therapeutic results of testicular tumors on the basis of results given in literature and of own investigations performed at the Clinic and Policlinic for Radiotherapy at Wuerzburg. In total, 97 patients with testicular tumors were examined and their cases analysed. These patients had received radiotherapy between January 1, 1962 and December 31, 1979. The difficulties with the intended classification of testicular tumors and the advantages and disadvantages of the individual nomenclatures are described. Consideration of the affected age-groups showed that this disease concerns mainly younger males with a high life expectancy. The study depicts the relatively discrete symptoms and signs and the difficulties connected with clinical diagnosis. A more generous indication for the exposition of the testicles is demanded. Also the lymphatic drainage of the testicular region, the resulting paths of metastatic spread and the difficulties connected with the lymphographic detection of metastases are described. There are three therapeutic measures: surgical intervention, radiotherapy and cytostatic treatment. With seminomas mandatory semitestectomy and radiotherapy will suffice; with other affections than seminomas, semitestectomy shall be followed by a combined therapy comprising removal of lymphatic nodes and cytostatic treatment and not so much radiotherapy. The results of treatment given in literature are compared with the own results. This comparison revealed good success with treatment of seminomas. With non-seminomal affections exclusive radiotherapy appears to be insufficient. Therefore a combined therapy is postulated, which must be rendered possible by a good interdisciplinary cooperation of pathologists, urologists and radiologists. (orig.) [de

    Testis tumors in children occur infrequently and exibit differences in their histopathology, clinical behaviour and therapy from their adult counterparts. From 1979 to 1994, 17 children and adolescent with testicular tumors were treated at the Pediatric Surgical Department of Vicenza Regional Hospital. Paratesticular rabdomiosarcoma were present in 3 cases, 4 patients had embrional carcinoma, 1 Sertoli cell tumor, 2 Leydig cell gonadal stromal tumor, and leukemic infiltrates of the testis were clinically evident in 7 patients. We report our clinical series and discuss in relation to clinical characteristic, histopathology and therapy and conclude that the improved survival during the past decade is attributable to better diagnostic imaging thecniques, the availability of serum tumor markers to monitor disease activity and more effective chemotherapy.

    Testicular germ cell tumors (TGCTs) are the most common solid tumors in young adult men. They constitute a unique pathology because of their embryonic and germ origin and their special behavior. Genetic predisposition, environmental factors involved in their development and genetic aberrations have been under study in many works throughout the last years trying to explain the susceptibility and the transformation mechanism of TGCTs. Despite the high rate of cure in this type of tumors because its particular sensitivity to cisplatin, there are tumors resistant to chemotherapy for which it is needed to find new therapies. In the present work, it has been carried out a literature review on the most important molecular aspects involved in the onset and development of such tumors, as well as a review of the major developments regarding prognostic factors, new prognostic biomarkers and the possibility of new targeted therapies.

  20. Testicular adrenal rest tumor in infertile man with congenital adrenal hyperplasia: case report and literature review

    Directory of Open Access Journals (Sweden)

    Giovanni Scala Marchini

    Full Text Available CONTEXT: Synthesis of cortisol and aldosterone is impaired in patients with congenital adrenal hyperplasia (CAH because of 21-hydroxylase deficiency. Men with CAH have low fertility rates compared with the normal population, and this is related to testicular adrenal rest tumors. Findings of azoospermia in combination with a testicular tumor on ultrasound are likely to have a mechanical cause, especially when in the testicular mediastinum. The preferred treatment method consists of intensive corticoid therapy. However, when the tumor is unresponsive to steroid therapy, surgical treatment should be considered. CASE REPORT: We present the case of a male patient with CAH due to 21-hydroxylase deficiency who presented a testicular tumor and azoospermia. Treatment with low daily corticoid doses had previously been started by an endocrinologist, but after 12 months, no significant change in sperm count was found. Although the adrenocorticotrophic hormone and 17-hydroxyprogesterone levels returned to normal values, the follicle-stimulating hormone (FSH, luteinizing hormone and testosterone levels remained unchanged. Ultrasound examination confirmed that the testicles were small and heterogenous bilaterally, and revealed a mosaic area at the projection of the testis network bilaterally. Magnetic resonance imaging confirmed the finding. Testicular biopsy revealed the presence of preserved spermatogenesis and spermiogenesis in 20% of the seminiferous tubules in the right testicle. The patient underwent testis-sparing tumor resection. After 12 months of follow-up, there was no tumor recurrence but the patient still presented azoospermia and joined an intracytoplasmic sperm injection program.

    Testicular germ cell tumors (TGCT) are the most common cancer among men ages 15 to 35 years in the United States. The well-established TGCT risk factors cryptorchism, prior diagnosis of TGCT, and family history of testicular cancer indicate that exposures in early life and/or in the familial setting may be critical to determining risk. Previous reports of familial clustering of lung cancer in mothers and testicular cancers in sons suggest that passive smoking in childhood may be such an exposure. To clarify the relationship of passive smoking exposure to TGCT risk, data from 754 cases and 928 controls enrolled in the Servicemen's Testicular Tumor Environmental and Endocrine Determinants study were analyzed. Data from 1,086 mothers of the cases and controls were also examined. Overall, there was no relationship between maternal [odds ratio (OR), 1.1; 95% confidence interval (95% CI), 0.9-1.3] or paternal smoking (OR, 1.0; 95% CI, 0.8-1.3) and TGCT risk. Although living with a non-parent smoker was marginally related to risk (OR, 1.4; 95% CI, 1.0-2.1), there was no relationship with number of smokers, amount smoked, or duration of smoking. Responses from both case-control participants and mothers also revealed no relationship between either maternal smoking while pregnant or while breast-feeding. Results did not differ by TGCT histology (seminoma, non-seminoma). These results do not support the hypothesis that passive smoking, either in utero or in childhood, is related to risk of TGCT. Other early life exposures, however, may explain the familial clustering of lung cancer in mothers and TGCT in sons.

    Full Text Available Abstract Transverse testicular ectopia (TTE is a rare anomaly in which both testes descend through a single inguinal canal. We report a case of yolk sac tumor in the ectopic testis of a patient with TTE. A 24-year-old man presented to our hospital with a left inguinal-mass, right cryptorchidism and elevated alpha-fetoprotein (AFP. A left herniotomy 3 years earlier demonstrated both testes in the left scrotum, one above another positionally. Four months ago, a left scrotal mass appeared and radical orchiectomy of both testes revealed testicular yolk sac tumor of the ectopic testis. An enlarging left inguinal-mass appeared 2 months ago and he was referred to our hospital. Laboratory data showed an elevation of AFP (245.5 ng/ml and a 46 XY karyotype. He underwent bilateral retroperitoneal lymph node dissection and simultaneous left inguinal mass dissection. Histopathologic examination revealed a diagnosis of recurrent yolk sac tumor in the left inguinal mass. The retroperitoneal lymph node was not enlarged and, on histopathology, was not involved. The patient has now been followed up for 8 months without evidence of biochemical or radiological recurrence.

    Testicular germ cell tumours (TGCT) represent 1%-1.5% of all male neoplasms, and they have the highest prevalence among men between 15 and 35 years old. Synchronous bilateral disease is a rare presentation, and the ratio of metachronous to synchronous bilateral disease is about 4 : 1. Several studies have suggested a correlation between male infertility and testicular cancer, with a 20-fold increase in the incidence of testicular cancer in infertile patients compared with the general population. At the time of diagnosis, 50%-75% of patients with unilateral TGCT present with subfertility; almost 13% of the patients are azoospermic before treatment, and up to two-thirds of patients become azoospermic following adjuvant cancer therapies. Therefore, fertility preservation should be considered in all oncological treatments. The only available option to preserve the reproductive potential in azoospermic patients with testicular cancer is to perform an onco-testicular sperm extraction (onco-TESE) before cancer treatment. In this paper, we describe a rare case of a patient with synchronous bilateral testicular cancer and azoospermia who was submitted to onco-TESE, sperm cryopreservation, and which was followed by the delivery of a healthy baby after intracytoplasmic sperm injection (ICSI), emphasising the importance of fertility preservation in oncology patients. © 2014 Blackwell Verlag GmbH.

    Full Text Available Germ cell tumors constitute the majority of all testicular tumors, which are relatively rare overall and are mainly encountered in young adults and teenagers. The term ‘burned-out’ germ cell tumor refers to the presence of a metastatic germ cell tumor with histological regression of the primary testicular lesion. Clinical examination of the testes and scrotal sonography is pivotal in the initial diagnosis of such neoplasms. We present a case of a 31-year-old male with a retroperitoneal mass and no palpable lesion on testicular examination.

    Androgen levels during critical periods of testicular development may be involved in the etiology of testicular germ cell tumors (TGCT). We evaluated the roles of adolescent and early adult life correlates of androgen exposure and TGCT in a hospital-based case control study. TGCT cases (n=187) and controls (n=148), matched on age, race and state of residence, participated in the study. Unconditional logistic regression was used to estimate associations between TGCT and male pattern baldness, severe acne, markers of puberty onset and body size. Cases were significantly less likely to report hair loss than controls (OR, 0.6; 95% CI, 0.4, 1.0). Amount of hair loss, increasing age at onset and increasing rate of loss were all inversely associated with TGCT (rate of hair loss: p-trend=0.03; age at onset: p-trend=0.03; amount of hair loss: p-trend=0.01). History of severe acne was inversely associated with TGCT (OR, 0.5; 95% CI, 0.3, 0.9) and height was positively associated with TGCT (p-trend=0.02). Increased endogenous androgen levels during puberty and early adulthood may be associated with decreased risk of TGCT. Additional studies of endogenous hormone levels during puberty and early adult life are warranted, especially studies evaluating the role of androgen synthesis, metabolism and uptake. PMID:21128977

    2015-01-01

    Full Text Available Sarcoidosis is an idiopathic, systemic disease that rarely involves the genitourinary tract. Here, we present a case of a 40-year-old male presented with bilateral scrotal swelling. The scrotal ultrasound showed multiple echogenic masses bilaterally ranging between 3 mm and 15 mm involving both testicles. Enlarged retroperitoneal lymph nodes were detected on the abdominal computed tomography (CT. Surgical exploration of the testes with a frozen section analysis of the left testicular mass was carried out, and it revealed noncaseating granulomas. CT scan of the chest revealed the classic bilateral hilar and mediastinal lymphadenopathy with reticulonodular infiltrates. The final pathological diagnosis was systemic sarcoidosis with bilateral testicular involvement. Treatment with high-dose corticosteroids resulted in complete resolution of the testicular mass and a significant decrease in the size of the hilar, mediastinal, and retroperitoneal lymphadenopathy.

    Introduction: Testicular tumors in children and adolescents are rare diseases with very good prognosis. Biological characteristics of germ cell tumors depends on the type of histology, stage and age at the time of diagnosis. Case report: 14 years old boy was urgently admitted to the hospital because of hemoptysis. Chest X ray showed round shaped lesions bilaterally. Surprisingly, extremely enlarged left testicle was found. Ultrasound confirmed tumor in left testicle, tumor markers were elevated and dissemination in lungs, retroperitoneal lymph nodes and CNS as well, was present. Despite three chemotherapeutic regimens the patient died 8 months from the diagnosis. Conclusions: Testicular tumors in adolescent boys are usually diagnosed in advanced stage after several months history of continuous enlargement. Whole body examination of patients and self examination of testicles in pubertal boys could lead to earlier diagnosis and improve the chance to cure. (author)

    A case of testicular choriocarcinoma is reported in which blood mixed stools and haemoptysis were the presenting manifestations as the patient never told about the testicular swelling to his parents. Orchidectomy was performed but the patient presented again with massive hematemesis due to gastric perforation secondary to gastric metastasis. The size of the testis at diagnosis was approximately 12 x 7cm. This was also unusual as testicular choriocarcinoma presents as a small mass. The patient eventually died of the complications within one month of diagnosis. (author)

    Localized primary periosteal amyloid tumors are extremely rare. A case of bilateral tibial amyloid tumor is presented. A 62-year-old woman initially presented with a painful mass in the anterior aspect of the right leg. There was no evidence of underlying systemic disease, including chronic infection or malignancy. Based on the results of resistance with Congo red staining to treatment with potassium permanganate and positivity for kappa light chain, we classified this particular case as AL-type amyloidosis. The patient noticed a swelling in the opposite leg 2 years later. The second tumor was also an AL-type amyloidoma. Amyloid tumors are generally solitary. This is the first case of bilateral periosteal amyloid tumors of the AL-type occurring in the tibiae. (orig.)

    Full Text Available Introduction: The incidence of tumors of the upper urothelium is high in our country, apart from their relation to specific regions (BEN and PBEN and their frequent bilateralism. Bilateral forms are present in significant percentage and are followed, in most cases, by renal failure, which speaks in favor of conservative surgery, if possible. Objective: The aim of the study was to present epidemiological, pathoanatomical and clinical characteristics of bilateral tumors of the upper urothelium and evaluate the Results of their treatment. Method: Our retrospective study analyzed 12 patients with bilateral tumors of the upper urothelium who were treated in the period from 1992 to 1996, according to their epidemiological, clinical, pathoanatomical and pathohistological characteristics, type of surgical treatment and relevant success. Results: In the observed period, bilateral tumors of the upper urothelium were found in 8.2% of our patients. In the group of 12 patients, 5 females and 7 males, 11 cases were from the region of Balkan Endemic Nephropathy (BEN. Renal failure was recorded in high percentage (66%. Radical surgical treatment - total nephroureterectomy was performed in 9 kidney units, and conservative operation in 15 units. Relapse significantly depended on tumor stage and grade, not on type of surgical treatment in the majority of cases. Five-year survival was 58.33%; major cause of death was associated with further evolution of tumor, recurrence and tumor dissemination, respectively, while renal failure complications were the cause of death in one case. Conclusion: The success of treatment mainly depends on tumor stage and grade and not on type of surgical Method in conservative treatment, but renal failure and its complications are an important risk factor in these patients.

    Full Text Available Testicular tumors are the most common form of solid cancer in young men. According to the 2004 WHO classification, testicular germ cell tumors (TGCT may present with different histological types. Embryonic cells of varying grade may be a source of TGCT and the occurrence of this type of tumors is directly related to the formation of a pool of male sex cells and gametogenesis. The paper gives information on mo- lecular stages for the process of formation of male sex cells in health, as well as ways of their impairments leading to TGCT. An investigation of the profiles of gene expression and the spectrum of molecular damages revealed genes responsible for a predisposition to the sporadic and hereditary forms of TGCT. The paper presents the current molecular genetic and clinicomorphological characteristics of TGCT. 

  7. Origins and molecular biology of testicular germ cell tumors.

    Science.gov (United States)

    Reuter, Victor E

    2005-02-01

    Testicular germ cell tumors can be divided into three groups (infantile/prepubertal, adolescent/young adult and spermatocytic seminoma), each with its own constellation of clinical histology, molecular and clinical features. They originate from germ cells at different stages of development. The most common testicular cancers arise in postpubertal men and are characterized genetically by having one or more copies of an isochromosome of the short arm of chromosome 12 [i(12p)] or other forms of 12p amplification and by aneuploidy. The consistent gain of genetic material from chromosome 12 seen in these tumors suggests that it has a crucial role in their development. Intratubular germ cell neoplasia, unclassified type (IGCNU) is the precursor to these invasive tumors. Several factors have been associated with their pathogenesis, including cryptorchidism, elevated estrogens in utero and gonadal dysgenesis. Tumors arising in prepubertal gonads are either teratomas or yolk sac tumors, tend to be diploid and are not associated with i(12p) or with IGCNU. Spermatocytic seminoma (SS) arises in older patients. These benign tumors may be either diploid or aneuploid and have losses of chromosome 9 rather than i(12p). Intratubular SS is commonly encountered but IGCNU is not. The pathogenesis of prepubertal GCT and SS is poorly understood.

    Full Text Available The androgen insensitivity (testicular feminization syndrome was described by Morris in phenotypic females with 46XY karyotype, presenting with primary amenorrhea, adequate breast development, and absent or scanty pubic or axillary hair. Gonads consist usually of seminiferous tubules without spermatogenesis. These patients have a 5-10% risk of developing germ cell tumors, usually after the complete development of secondary female sexual characteristics. We hereby report a case considered as a female with married life of 15 years, who was operated for severe abdominal pain. Phenotype characters were that of female. Microscopic examination of the tumor from the abdomen revealed germinoma and yolk sac tumor with adjacent seminiferous tubules. Karyotyping showed 46XY. Final diagnosis of malignant mixed germ cell tumor in androgen insensitivity syndrome was made. Surveillance may be the most appropriate option when these conditions are initially diagnosed in adulthood to prevent development of germ cell tumors.

    We report a case of juvenile allergic urethritis secondary to double concentrate orange squash of a famous brand in a 3-year-old boy who developed bilateral urethro-ejaculatory reflux (UER) and severe urethral, perineal and scrotal pain referred to both lower limbs intermittently predominantly during and after micturition-simulating features of bilateral intermittent testicular torsion. Accurate history, urinalysis, ultrasound, colour Doppler and food challenge were helpful in diagnosis. Topical steroids, antihistaminic, analgesic and anti-inflammatory medications together with withdrawal of the allergen produced complete recovery. Allergic urethritis in association with bilateral UER causing secondary seminal vesiculitis and epididymitis is rare. It presented as acute scrotum and responded to innovative treatment. Allergic disease can have a dramatic effect on a child's quality of life. This is the first documented case of allergic urethritis and associated UER presenting as juvenile acute scrotum. Steroids, antihistamines and anti-inflammatory agents together with avoidance of the allergen helped achieve recovery. 2015 BMJ Publishing Group Ltd.

  10. Bilateral carotid body tumor resection in a female patient

    Full Text Available Introduction: Carotid body tumors also called carotid paragangliomas are rare neuroendocrine neoplasms derived from neural crest cells, approximately 3% of all paragangliomas occur in the head and neck area (Xiao and She, 2015; although they represent 65% of the head and neck paragangliomas (Georgiadis et al., 2008. Presentation of case: We present the therapeutic management of a 65-year-old woman with bilateral carotid body tumors. The patient presented to medical clinic for unrelated signs and symptoms of weight loss, dyspepsia, and epigastric pain. Physical examination showed bilateral non-tender neck masses for which imaging studies were ordered resulting in the diagnosis of bilateral carotid tumor. Surgical resection was staged with one week of distance between each tumor resection. Discussion: Carotid Body Tumors can arise from the paraganglia located within the adventitia of the medial aspect of the carotid bifurcation.Resection is the only curative treatment. Carotid body tumors resection represents a special challenge due to potential neurovascular complications. Conclusions: Surgical resection of carotid body tumors represents a special challenge to the surgeon because of the complex anatomical location of the tumor, including close relationship with the cranial nerves, involvement of the carotid vessels and large vascularization of the tumor. With the advance of diagnosis and improvement in surgical techniques as well as the understanding of biological behavior of tumors, surgical treatment has become a safer alternative for treating these tumors.

  11. Endogenous DNA Damage and Risk of Testicular Germ Cell Tumors

    2008-01-18

    Testicular germ cell tumors (TGCT) are comprised of two histologic groups, seminomas and nonseminomas. We postulated that the possible divergent pathogeneses of these histologies may be partially explained by variable endogenous DNA damage. To assess our hypothesis, we conducted a case-case analysis of seminomas and nonseminomas using the alkaline comet assay to quantify single-strand DNA breaks and alkali-labile sites. The Familial Testicular Cancer study and the U.S. Radiologic Technologists cohort provided 112 TGCT cases (51 seminomas & 61 nonseminomas). A lymphoblastoid cell line was cultured for each patient and the alkaline comet assay was used to determine four parameters: tail DNA, tail length, comet distributed moment (CDM) and Olive tail moment (OTM). Odds ratios (OR) and 95% confidence intervals (95%CI) were estimated using logistic regression. Values for tail length, tail DNA, CDM and OTM were modeled as categorical variables using the 50th and 75th percentiles of the seminoma group. Tail DNA was significantly associated with nonseminoma compared to seminoma (OR{sub 50th percentile} = 3.31, 95%CI: 1.00, 10.98; OR{sub 75th percentile} = 3.71, 95%CI: 1.04, 13.20; p for trend=0.039). OTM exhibited similar, albeit statistically non-significant, risk estimates (OR{sub 50th percentile} = 2.27, 95%CI: 0.75, 6.87; OR{sub 75th percentile} = 2.40, 95%CI: 0.75, 7.71; p for trend=0.12) whereas tail length and CDM showed no association. In conclusion, the results for tail DNA and OTM indicate that endogenous DNA damage levels are higher in patients who develop nonseminoma compared with seminoma. This may partly explain the more aggressive biology and younger age-of-onset of this histologic subgroup compared with the relatively less aggressive, later-onset seminoma.

    2017-11-09

    Testicular cancer represents approximately 1% of all cancers diagnosed in males. The prevalence of bilateral testicular germ cell tumor cases varies from 1% to 5%. Intratubular germ cell neoplasia (ITGCN) is a precursor for almost all testicular germ cell tumors (TGCT) and is one of the highest risks of developing contralateral testicular cancer. The radical orchiectomy is still preferred for the treatment of testicular cancer. However, in some cases like solitary testis, bilateral cancer or if the tumor size is under 30% percent of the testicular extent, organ-sparing surgery can be an option. There are just a few published reports of metachronous contralateral testicular cancer, developed after orchiectomy with the histopathology of the intratubular germ cell neoplasia.

    2017-06-01

    The International Society of Urological Pathology held a conference devoted to issues in testicular and penile pathology in Boston in March 2015, which included a presentation and discussion led by the testis microscopic features working group. This conference focused on controversies related to staging and reporting of testicular tumors and was preceded by an online survey of the International Society of Urological Pathology members. The survey results were used to initiate discussions, but decisions were made by expert consensus rather than voting. A number of recommendations emerged from the conference, including that lymphovascular invasion (LVI) should always be reported and no distinction need be made between lymphatic or blood invasion. If LVI is equivocal, then it should be regarded as negative to avoid triggering unnecessary therapy. LVI in the spermatic cord is considered as category pT2, not pT3, unless future studies provide contrary evidence. At the time of gross dissection, a block should be taken just superior to the epididymis to define the base of the spermatic cord, and direct invasion of tumor in this block indicates a category of pT3. Pagetoid involvement of the rete testis epithelium must be distinguished from rete testis stromal invasion, with only the latter being prognostically useful. Percentages of different tumor elements in mixed germ cell tumors should be reported. Although consensus was reached on many issues, there are still areas of practice that need further evidence on which to base firm recommendations.

    Testicular adrenal rest tumours are frequently associated with congenital adrenal hyperplasia (CAH). These ACTH-dependent tumours cannot be easily distinguished histologically from Leydig-cell tumours. We report the case of a 30-year-old man who was explored for infertility, azoospermia and unilateral testicular tumour. High levels of 17-OH progesterone and ACTH, low cortisol and undetectable gonadotropins levels, associated to bilateral adrenal hyperplasia, led to the diagnosis of CAH by 21-OH deficiency with a composite heterozygoty. The testicular tumour was first considered as adrenal rest. However, histological analysis of this unilateral painful tumour showed a steroid-hormone-secreting cell proliferation with atypical and frequent mitosis. To discriminate between a benign adrenal rest tumour and a possible malignant leydigioma, tumoral expression of specific gene products was analyzed by RT-PCR. No 11-beta-hydroxylase nor ACTH receptor mRNAs could be found in the tumour, which did not behave like usual adrenal rest cells. For this unilateral testicular tumour, the lack of adrenal-specific markers associated with a high rate of mitosis and pleiomorphism supported a leydigian origin with malignant potential. However, lack of tumoral LH-R mRNA expression and a tumour-free 3-year follow-up led us to retain the diagnosis of adrenal rest tumour with loss of adrenal gene expression and progressive autonomous behaviour.

    Testicular cancers are an uncommon and highly curable group of tumors that are typically managed by specialist multidisciplinary teams (MDTs). Although recent guidelines have emphasized the importance of tumor prognostic factors in predicting recurrence and personalizing therapy in early-stage disease, the role of central pathology review in determining these factors is unclear. We compared the referral histopathology reports with those obtained after expert central review for all cases reviewed by the UK Thames Valley Cancer Network testicular tumor MDT from August 2004 to September 2012. For cases in which the findings differed, we recorded the effect of the alteration on the estimates of patient prognosis and predicted clinical management using international (European Society of Medical Oncology [ESMO]) and local guidelines. The histopathology reports were altered after central review in 129 of 465 cases (27.7%) referred to the testicular tumor MDT during the study period. These resulted in changes in the estimation of prognosis for 42 patients (9.0% total), with a predicted affect on management according to the ESMO guidelines in 30 cases (6.5%). These proportions were broadly similar for both seminoma and nonseminoma, although the reasons for the discrepancies differed between the 2 (principally errors in categorization of rete testis invasion in seminoma and of lymphovascular invasion in nonseminoma). Changes to the tumor type were uncommon (2 cases). Central MDT review results in frequent, clinically relevant alterations to testicular tumor histopathology reports for testicular tumors. The results of our study demonstrate the importance of specialist MDTs to inform patient-centered care and ensure best practice in the management of these uncommon cancers.

    While testicular adrenal rest tumor is generally a rare intratesticular tumor, it is frequent in patients with congenital adrenal hyperplasia. The tumors are diagnosed and followed up by ultrasound examination because these tumors are non-palpable and symptomless in most cases and always benign. Ultrasound imaging features change depending on how congenital adrenal hyperplasia is controlled. We herein report three cases of testicular adrenal rest tumors with different usual and unusual imaging findings and follow-up imaging. Patient 1 was a 14-year-old boy who presented with poor compliance to medication. Patient 2 and 3 were a 10-year-old and 13-year-old boy who presented with precocious puberty and short stature, respectively. Ultrasound examinations demonstrated oval hypoechoic masses and irregular speculated hyperechoic masses in the testes and different serial imaging findings.

    Cisplatin (CDDP) resistance in testicular germ cell tumors (GCTs) is still a clinical challenge, and one associated with poor prognosis. The purpose of this work was to test pazopanib, an anti-tumoral and anti-angiogenic multikinase inhibitor, and its combination with lapatinib (an anti-ErbB inhibitor) in mouse orthotopic models of human testicular GCTs. We used two different models of human testicular GCTs orthotopically grown in nude mice; a CDDP-sensitive choriocarcinoma (TGT38) and a new orthotopic model generated from a metastatic GCT refractory to first-line CDDP chemotherapy (TGT44). Nude mice implanted with these orthotopic tumors were treated with the inhibitors and the effect on tumoral growth and angiogenesis was evaluated. TGT44 refractory tumor had an immunohistochemical profile similar to the original metastasis, with characteristics of yolk sac tumor. TGT44 did not respond when treated with cisplatin. In contrast, pazopanib had an anti-angiogenic effect and anti-tumor efficacy in this model. Pazopanib in combination with lapatinib in TGT38, an orthotopic model of choriocarcinoma had an additive effect blocking tumor growth. We present pazopanib as a possible agent for the alternative treatment of CDDP-sensitive and CDDP-refractory GCT patients, alone or in combination with anti-ErbB therapies

    Full Text Available Giant cell tumor of tendon sheath arises from the synovium of tendon sheaths, joints, or bursae, mostly affects adults between 30 and 50 years of age, and is slightly more common in females. We report the case of a 32-years-old male presenting with pain in both ankles without any history of trauma. On clinical examination, tenderness on both tendoachilles and local thickening were observed. Ultrasonography showed thickening of local tendinous area with increase in anteroposterior diameter, and Doppler demonstrated increased flow in peritendinous area. MRI findings showed that most of the tumor had intermediate signal intensity and portions of the tumor had low signal intensity. Fine needle aspiration cytology confirmed the diagnosis of giant cell tumor of tendon sheath. Excision biopsy was done with no recurrence on five month follow-up. Review of literature did not reveal any similar result; so, bilateral giant cell tumor of tendon sheath of tendoachilles is a rare presentation.

    To evaluate the presence of antisperm antibodies in testicular cancer patients 1 month after orchiectomy and before radiotherapy or chemotherapy. Clinical study. Department of andrology and seminology at a university hospital. One hundred ninety patients with testicular cancer. Determination of semen parameters and autoimmune reaction evaluated on the sperm surface and in blood serum. Autoimmune reaction on the sperm surface by the direct immunobead test (IBT), and in blood serum by the indirect IBT and the gelatin agglutination test (GAT), was evaluated 1 month after orchiectomy and before beginning chemotherapy or radiotherapy. Of the 190 patients, 11 (5.8%) were positive for antisperm antibody by GAT. On indirect IBT, 3 of the 11 GAT-positive patients were positive to IgG class only, with values of 22%, 24%, and 40%. Of the 11 GAT-positive patients, 4 showed no antibody bound to the sperm surface, and 3 were positive to IgG class only (28%, 21%, and 38%), with binding exclusively on the tail. Direct IBT could not be performed in the remaining 4 patients. Our data support the hypothesis that testicular cancer might not be a possible cause of antisperm autoimmunization and infertility.

    Uterine leiomyomas are the most common benign uterine neoplasms. Undegenerated uterine leiomyomas are easily recognizable by the typical imaging findings on radiologic studies. However, degenerated fibroids can have unusual and variable appearances. The atypical appearances due to degenerative changes may cause confusion in diagnosis of leiomyomas. In this article, we report a case of a patient with extensive cystic and myxoid degeneration of uterine leiomyoma, mimicking malignant bilateral ovarian surface epithelial tumors.

    The purpose of this study was to evaluate whether initial diagnostic technique influenced the ability to identify anaplastic histology, to determine the time interval to diagnosis of anaplasia, and to delineate the incidence of discordant pathology in bilateral Wilms' tumor. We hypothesized that delay in diagnosis of anaplasia could affect time to appropriate surgery and intensive multimodality therapy. One hundred eight-nine children were enrolled in the fourth National Wilms' Tumor Study with synchronous bilateral tumors, 27 of whom were eventually shown to have anaplastic histology. Initial diagnostic technique, time interval to diagnosis of anaplasia, and the incidence of discordant pathology were determined. Anaplasia was identified in 0 of 7 tumors by core needle biopsy, 3 of 9 tumors by open wedge biopsy, and in 7 of 9 cases by partial or complete nephrectomy. The mean duration of first chemotherapy regimen (DD or EE) was 20, 39, and 36 weeks, respectively, before anaplasia was identified at second surgery. Discordant pathology between bilateral tumors was identified on final tissue diagnosis in 20 patients. Only 4 patients had anaplastic tumors in both kidneys. Core needle biopsy did not identify anaplasia in 7 of 7 children. Open biopsy or partial/complete nephrectomy identified anaplasia at initial diagnostic procedure in 10 of 18 children. Twenty of 24 patients at final tissue diagnosis had discordant pathology between the 2 kidneys. Earlier interval incisional biopsy or resection may identify anaplastic histology and limit the duration of chemotherapy targeted to favorable histology for children with bilateral Wilms' tumor and anaplasia.

    Purpose: To determine whether the time interval to development of second tumor is a prognostic factor for overall survival in children with metachronous bilateral Wilms' tumor and to give a recommendation regarding screening of the contralateral kidney in patients with Wilms' tumor. Materials and Management: A literature search using MEDLINE was performed of manuscripts in the English language from 1950-1996 and identified 108 children with metachronous bilateral Wilms' tumor. Children were classified according to time interval to development of a contralateral Wilms' tumor ( 78 mos (2), 78 - < 84 mos (1), 84 - < 90 mos (0), 90 - < 96 mos (1), ≥ 96 mos (0). Analysis of overall survival in patients with a time interval of < 18 months and ≥ 18 months showed a 10 year survival of 39.6% and 55.2%, respectively (p = 0.024, log-rank test). Conclusions: Children with metachronous bilateral Wilms' tumor who develop a contralateral tumor at a time interval of ≥ 18 months from the initial Wilms' tumor had a better overall survival than children with a time interval of < 18 months. Screening by abdominal ultrasound of the contralateral kidney for more than 5 years after initial diagnosis of Wilms' tumor may not be necessary since 102/106 (96.2%) of children had a time interval to second tumor of < 60 months

    Full Text Available 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. RAS gene mutations have also been reported in TGCTs. We investigated K-RAS and N-RAS mutations in seminoma and non-seminoma TGCT patients. A total of 24 (55% pure seminoma cases and 19 (45% non-seminoma cases were included in the study. K-RAS and N-RAS analyses were performed in our molecular pathology laboratory, using K-RAS and N-RAS Pyro Kit 24 V1 (Qiagen. In total, a RAS mutation was present in 12 patients (27%: 7 seminoma (29% and 5 non-seminoma cases (26% [p = 0.55]. A K-RAS mutation was present in 4 pure seminoma tumors (16% and 3 non-seminoma tumors (15% [p = 0.63], and an N-RAS mutation was observed in 4 seminoma tumors (16% and 3 non-seminoma tumors (15% [p = 0.63]. Both, K-RAS and N-RAS mutations were present in two patients: one with seminoma tumor and the other with non-seminoma tumor. To date, no approved targeted therapy is available for the treatment of TGCTs. The analysis of K-RAS and N-RAS mutations in these tumors may provide more treatment options, especially in platinum-resistant tumors.

    Wilms tumor (WT) with diffuse anaplasia has an unfavorable prognosis and is often (>70%) associated with mutations in the TP53 gene. Although most WTs are unilateral, 5-10% are bilateral, and they are almost always present with nephrogenic rests. The latter are considered a precursor of WT. Two cases of bilateral WTs with nephroblastomatosis, in which anaplastic changes were detected over a period of time, were analyzed using clinical, radiological, histopathological, and molecular-genetic data. TP53 was analyzed by direct sequencing of its full coding sequence and intron-exon boundaries in 11 fragments. DNA was extracted from paraffin-embedded or frozen specimens. High-resolution genomic copy number profiling was carried out by UCL Genomics on the Affymetrix Human Mapping 250K Nsp or Genome-Wide Human SNP Array 6.0 platform. Both cases demonstrated a strong association between the appearance of anaplastic clones and TP53 mutations. Synchronous ganglioneuroma was diagnosed in one case. Our cases are unique as they represent a long disease history and demonstrate the difficulties in managing rare cases of bilateral WT with anaplasia. These cases also emphasize the practical importance of modern molecular-genetic techniques and their clinical application. Moreover, they highlight the issue of the adequate sampling needed in order to gather comprehensive, efficient, and sufficient information about genetic events in a single tumor.

    Congenital adrenal hyperplasia (CAH) describes a group of inherited autosomal recessive disorders characterized by enzyme defects in the steroidogenic pathways that lead to the biosynthesis of cortisol, aldosterone, and androgens. Chronic excessive adrenocorticotropic hormone (ACTH) stimulation may result in hyperplasia of ACTH-sensitive tissues in adrenal glands and other sites such as the testes, causing testicular masses known as testicular adrenal rest tumors (TARTs).

    1989-01-01

    Complex gamma-camera and radioimmunologic study of the tumor markers AFP, β-HCG and CEA was performed in 7 patients with testicular tumors. In all tested patients gamma-camera scintigraphy of the testes clearly delineated the zone of the pathological process. Gamma-camera examination very well differentiates malignant from nonmalignant processes in the testes. The serum levels of the tumor markers AFP and β-HCG proved elevated in 3 of the tested patients during the preoperative period. The histological types of the tumors in these patients were: teratocarcinoma in one and embryonal carcinoma in the other two. It is believed that investigation of the three tumor markers may gain acceptance as additonal method in the complex diagnosis of these diseases

    We report a gastrointestinal stromal tumor (GIST) patient with male gynecomastia and testicular hydrocele after treatment with imatinib mesylate. A 42 yr-old male patient presented for management of hepatic masses. Two years earlier, he had undergone a small bowel resection to remove an intraabdominal mass later shown to be a GIST, followed by adjuvant radiation therapy. At presentation, CT scan revealed multiple hepatic masses, which were compatible with metastatic GIST, and he was prescribed imatinib 400 mg/day. During treatment, he experienced painful enlargement of the left breast and scrotal swelling. Three months after cessation of imatinib treatment, the tumors recurred, and, upon recommencing imatinib, he experienced painful enlargement of the right breast and scrotal swelling. He was diagnosed with male gynecomastia caused by decreased testosterone and non-communicative testicular hydrocele. He was given androgen support and a hydrocelectomy, which improved his gynecomastia. The mechanism by which imatinib induces gynecomastia and hydrocele is thought to be associated with an inhibition of c-KIT and platelet-derive growth factor. This is the first report, to our knowledge, describing concurrent male gynecomastia and testicular hydrocele after imatinib treatment of a patient with GIST. PMID:15953881

    Full Text Available Abstract The testicular yolk sac tumor (TYST is the most common neoplasm originated from germ cells differentiated abnormally, a major part of pediatric malignant testicular tumors. The present study aimed at developing and validating the in vitro and vivo models of TYST and evaluating the sensitivity of TYST to treatments, by cloning human TYST cells and investigating the histology, ultra-structure, growth kinetics and expression of specific proteins of cloned cells. We found biological characteristics of cloned TYST cells were similar to the yolk sac tumor and differentiated from the columnar to glandular-like or goblet cells-like cells. Chromosomes for tumor identification in each passage met nature of the primary tumor. TYST cells were more sensitive to all-trans-retinoic acid which had significantly inhibitory effects on cell proliferation. Cisplatin induced apoptosis of TYST cells through the activation of p53 expression and down-regulation of Bcl- expression. Thus, we believe that cloned TYST cells and the animal model developed here are useful to understand the molecular mechanism of TYST cells and develop potential therapies for human TYST.

  17. Critical Function of PRDM2 in the Neoplastic Growth of Testicular Germ Cell Tumors

    Directory of Open Access Journals (Sweden)

    Erika Di Zazzo

    2016-12-01

    Full Text Available Testicular germ cell tumors (TGCTs derive from primordial germ cells. Their maturation is blocked at different stages, reflecting histological tumor subtypes. A common genetic alteration in TGCT is a deletion of the chromosome 1 short arm, where the PRDM2 gene, belonging to the Positive Regulatory domain gene (PRDM family, is located. Expression of PRDM2 gene is shifted in different human tumors, where the expression of the two principal protein forms coded by PRDM2 gene, RIZ1 and RIZ2, is frequently unbalanced. Therefore, PRDM2 is actually considered a candidate tumor suppressor gene in different types of cancer. Although recent studies have demonstrated that PRDM gene family members have a pivotal role during the early stages of testicular development, no information are actually available on the involvement of these genes in TGCTs. In this article we show by qRT-PCR analysis that PRDM2 expression level is modulated by proliferation and differentiation agents such as estradiol, whose exposure during fetal life is probably an important risk factor for TGCTs development in adulthood. Furthermore in normal and cancer germ cell lines, PRDM2 binds estradiol receptor α (ERα and influences proliferation, survival and apoptosis, as previously reported using MCF-7 breast cancer cell line, suggesting a potential tumor-suppressor role in TGCT formation.

    Full Text Available Abstract Background Germ cell testicular tumors have survival rate that diminishes with high tumor marker levels, such as human chorionic gonadotropin (hCG. hCG may regulate vascular neoformation through vascular endothelial growth factor (VEGF. Our purpose was to determine the relationship between hCG serum levels, angiogenesis, and VEGF expression in germ cell testicular tumors. Methods We conducted a retrospective study of 101 patients. Serum levels of hCG, alpha-fetoprotein (AFP, and lactate dehydrogenase were measured prior to surgery. Vascular density (VD and VEGF tissue expression were determined by immunohistochemistry and underwent double-blind analysis. Results Histologically, 46% were seminomas and 54%, non-seminomas. Median follow-up was 43 ± 27 months. Relapse was present in 7.5% and mortality in 11.5%. Factors associated with high VD included non-seminoma type (p = 0.016, AFP ≥ 14.7 ng/mL (p = 0.0001, and hCG ≥ 25 mIU/mL (p = 0.0001. In multivariate analysis, the only significant VD-associated factor was hCG level (p = 0.04. When hCG levels were stratified, concentrations ≥ 25 mIU/mL were related with increased neovascularization (p Conclusion This is the first study that relates increased serum hCG levels with vascularization in testicular germ cell tumors. Hence, its expression might play a role in tumor angiogenesis, independent of VEGF expression, and may explain its association with poor prognosis. hCG might represent a molecular target for therapy.

    Anti-Ma2-associated encephalitis is a paraneoplastic disorder that predominantly affects the limbic system, diencephalon and brainstem, and is usually associated with tumors of the testis. We report a 35-year-old man with a right testicular mass who presented with multiple neurological complains, and clinical, serological and radiological features compatible with anti-Ma2-associated encephalitis. After three courses of carboplatin, etoposide and bleomycin for metastatic testicular germ-cell tumor, all elevated tumor markers normalized and the retroperitoneal metastases disappeared, but the neurological disorder deteriorated. To our knowledge, this is the first case in which orchiectomy followed by carboplatin, etoposide and bleomycin for a testicular tumor with anti-Ma2 encephalitis was performed.

    DNA damage response has been clearly described as an anti-cancer barrier in early human tumorigenesis. Moreover, interestingly, testicular germ cell tumors (TGCTs) have been reported to lack the DNA Damage Response (DDR) pathway activation. CCDC6 is a pro-apoptotic phosphoprotein substrate of the kinase ataxia telangectasia mutated (ATM) able to sustain DNA damage checkpoint in response to genotoxic stress and is commonly rearranged in malignancies upon fusion with different partners. In our study we sought to determine whether CCDC6 could have a role in the patho-genesis of testicular germ cell tumors. To achieve this aim, analysis for CCDC6 expression has been evaluated on serial sections of the mouse testis by immunohistochemistry and on separate populations of murine testicular cells by western blot. Next, the resistance to DNA damage-induced apoptosis and the production of reactive oxygen species has been investigated in GC1 cells, derived from immortalized type B murine germ cells, following CCDC6 silencing. Finally, the CCDC6 expression in normal human testicular cells, in Intratubular Germ Cell Neoplasia Unclassified (IGCNU), in a large series of male germ cell tumours and in the unique human seminoma TCam2 cell line has been evaluated by immunohistochemistry and by Western Blot analyses. The analysis of the CCDC6 expression revealed its presence in Sertoli cells and in spermatogonial cells. CCDC6 loss was the most consistent feature among the primary tumours and TCam2 cells. Interestingly, following treatment with low doses of H 2 O 2 , the silencing of CCDC6 in GC1 cells caused a decrease in the oxidized form of cytochrome c and low detection of Bad, PARP-1 and Caspase 3 proteins. Moreover, in the silenced cells, upon oxidative damage, the cell viability was protected, the γH2AX activation was impaired and the Reactive Oxygen Species (ROS) release was decreased. Therefore, our results suggest that the loss of CCDC6 could aid the spermatogonial cells to

    Persistent Müllerian duct syndrome (PMDS), a rare form of male pseudohermaphroditism in dogs, is an abnormal sexual phenotype in males that is characterized by the existence of a hypoplastic oviduct, uterus, and cranial part of the vagina. Dogs suffering from PMDS are often accompanied by cryptorchidism. To date, it has been mainly found in the Miniature Schnauzer breed. In this report, two cases of PMDS with a malignant testicular tumor originating from cryptorchidism in breeds other than the Miniature Schnauzer breed are described. The patients were a seven-year-old male Maltese dog and a 17-year-old male mixed-breed dog weighing 3.8 kg. They also exhibited an enlarged prostate with or without abscess and an elevated serum estradiol level and were surgically treated to remove the testicular tumor and Müllerian duct derivatives. It is recommended that PMDS should be differentially diagnosed by ultrasonography and that orchiectomy be performed at an early age in patients suspected to have cryptorchidism to prevent the ectopic testes from becoming tumorous.

    Full Text Available Neural-cadherin is a member of the cadherin gene family encoding the N-cadherin protein that mediates cell adhesion. N-cadherin is a marker of Sertoli cells and is also expressed in germ cells of varying stages of maturation. The purpose of this study was to determine the presence and distribution of this protein by immunohistochemistry in 105 germ cell tumors of both single and mixed histological types and 12 gonadal stromal tumors. Twenty-four germ cell tumors consisted of one cell type and the remaining were mixed. Of the 23 seminomas in either pure or mixed tumors, 74% were positive. Two spermatocytic seminomas were positive. Of the 83 cases with yolk sac tumor, 99% were positive for N-cadherin. The teratomas were positive in 73% in neuroectodermal and / or glandular components. In contrast, 87% of embryonal carcinomas did not express N-cadherin. Only 17% of the syncytiotrophoblastic cells were positive for N-cadherin. In conclusion, N-cadherin expression is very helpful in the identification of yolk sac tumors. In addition to glypican-3 and Sal-like protein 4, N-cadherin can be beneficial for the diagnosis and classification of this subtype of testicular germ cell tumor. Nine of the 12 gonadal stromal tumors were positive to a variable extent.

    Full Text Available Congenital adrenal hyperplasia (CAH describes a group of inherited autosomal recessive disorders characterized by enzyme defects in the steroidogenic pathways that lead to the biosynthesis of cortisol, aldosterone, and androgens. Chronic excessive adrenocorticotropic hormone (ACTH stimulation may result in hyperplasia of ACTH-sensitive tissues in adrenal glands and other sites such as the testes, causing testicular masses known as testicular adrenal rest tumors (TARTs. Leydig cell tumors (LCTs are make up a very small number of all testicular tumors and can be difficult to distinguish from TARTs. This distinction is interesting because LCTs and TARTs require different therapeutic approaches. Hereby, we present an unusual case of a 19-year-old patient with CAH due to 11β-hydroxylase deficiency, who presented with TARTs and an epididymal Leydig cell tumor.

    Full Text Available Abstract Introduction The self-mutilating patient is an unusual psychiatric presentation in the emergency room. Nonetheless, serious underlying psychiatric pathology and drug abuse are important background risk factors. A careful stepwise approach in the emergency room is essential, although the prognosis, follow-up, and eventual rehabilitation can be problematic. We present a unique and original case of bilateral self-castration caused by cannabis abuse. Case Presentation We report a case of a 40-year-old Berber man, who was presented to our emergency room with externalization of both testes using his long fingernails, associated with hemodynamic shock. After stabilization of his state, our patient was admitted to the operating room where hemostasis was achieved. Conclusion The clinical characteristics of self-mutilation are manifold and there is a lack of agreement about its etiology. The complex behavior associated with drug abuse may be one cause of self-mutilation. Dysfunction of the inhibitory brain circuitry caused by substance abuse could explain why this cannabis-addicted patient lost control and self-mutilated. To the best of our knowledge, this is the first case report which presents an association between self-castration and cannabis abuse.

    Purpose: This paper describes a feasibility study for developing a 35-MHz high-frequency ultrasound computed-tomography (HFUCT) system for imaging rat testicles. Methods: The performances of two kinds of HFUCT-attenuation and sound-speed UCT-based on transmission and pulse-echo modes were investigated in this study. Experiments were carried out using phantoms and actual rat testiclesin vitro. HFUCT images were reconstructed using a filtered backprojection algorithm. Results: The phantom experimental results indicated that all types of HFUCT can determine the dimensions of a plastic cylinder with a diameter of 500μm. Compared to sound-speed HFUCT, attenuation HFUCT exhibited a better performance in recognizing a tiny sclerosed region in a gelatin phantom. Therefore, the in vitro testicular experiments were performed using attenuation HFUCT based on transmission and pulse-echo modes. The experimentally measured attenuation coefficient and sound speed for healthy rat testicles were 2.92 ± 0.25 dB/mm and 1537 ± 25 m/s, respectively. Conclusions: A homogeneous texture was evident for healthy testicles using both modes. An artificial sclerosed tumor could also be clearly observed using two- and three-dimensional attenuation HFUCT in both modes. However, an object artifact was apparent in pulse-echo mode because of ultrasound beam refraction. All of the obtained experimental results indicate the potential of using HFUCT as a novel tool for monitoring the preclinical responses of testicular tumors in small animals.

    Testicular tumors most frequently metastasize to regional lymph nodes. Non-seminomatous tumor metastasis of testicle (NSGCTT) to the eyeball is rare. We presented a 24-year old man, referred to the ophthalmologist due to acute pain and abrupt loss of sight in the left eye accompanied by its enlargement. Orbital and endocranial computerized tomography (CT) was carried out, indicating the tumor in the left eye. His previous medical history provided the information that the right testicle was painlessly enlarged for 8 months. Ultrasonography showed a completely tumorously altered testis. Abdominal and chest CT failed to reveal any secondary deposits in visceral organs and lymph glands. Tumor markers (AFP - alpha-fetoproteins, beta hCG - human choronic gonadotropin beta) were elevated. Right radical orchiactomy was performed (showed NSGCTT), followed by polychemotherapy with cisplatinum 100 mg/m2, etoposide 120 mg/m2, bleomycin 15 mg/m2 (PEB x 4), resulting in normalization of tumor marker values and significant regression of the left eyeball. Next, the left eye enucleation and ocular prosthesis implantation was carried out. Pathohistological evaluation indicated fibrosis and necrosis only. In a 5-year follow-up period, the patient was free of recurrence. Isolated hematogenous metastasis of the NSGCTT to the eye is rare. In our case, the left eye was the only metastatic localization. After chemotherapy and eye enucleation the patient was in a 4-year follow-up period free of the recurrence.

    Increased risks of solid tumors after older radiotherapy strategies for testicular cancer (TC) are well established. Few population-based studies, however, focus on solid cancer risk among survivors of TC managed with nonradiotherapy approaches. We quantified the site-specific risk of solid cancers among testicular nonseminoma patients treated in the modern era of cisplatin-based chemotherapy, without radiotherapy. Standardized incidence ratios (SIRs) for solid tumors were calculated for 12,691 patients with testicular nonseminoma reported to the population-based Surveillance, Epidemiology, and End Results program (1980 to 2008) and treated initially with either chemotherapy (n = 6,013) or surgery (n = 6,678) without radiotherapy. Patients accrued 116,073 person-years of follow-up. Two hundred ten second solid cancers were observed. No increased risk followed surgery alone (SIR, 0.93; 95% CI, 0.76 to 1.14; n = 99 solid cancers), whereas significantly increased 40% excesses (SIR, 1.43; 95% CI, 1.18 to 1.73; n = 111 solid cancers) occurred after chemotherapy. Increased risks of solid cancers after chemotherapy were observed in most follow-up periods (median latency, 12.5 years), including more than 20 years after treatment (SIR, 1.54; 95% CI, 0.96 to 2.33); significantly increased three- to seven-fold risks occurred for cancers of the kidney (SIR, 3.37; 95% CI, 1.79 to 5.77), thyroid (SIR, 4.40; 95% CI, 2.19 to 7.88), and soft tissue (SIR, 7.49; 95% CI, 3.59 to 13.78). To our knowledge, this is the first large population-based series reporting significantly increased risks of solid cancers among patients with testicular nonseminoma treated in the modern era of cisplatin-based chemotherapy. Subsequent analytic studies should focus on the evaluation of dose-response relationships, types of solid cancers, latency patterns, and interactions with other possible factors, including genetic susceptibility.

    Testicular germ cell tumors (TGCT) are the most common cancer entities in young men with increasing incidence observed in the last decades. For therapeutic management it is important, that TGCT are divided into several histological subtypes. MED15 is part of the multiprotein Mediator complex which presents an integrative hub for transcriptional regulation and is known to be deregulated in several malignancies, such as prostate cancer and bladder cancer role, whereas the role of the Mediator complex in TGCT has not been investigated so far. Aim of the study was to investigate the implication of MED15 in TGCT development and its stratification into histological subtypes. Immunohistochemical staining (IHC) against Mediator complex subunit MED15 was conducted on a TGCT cohort containing tumor-free testis (n = 35), intratubular germ cell neoplasia unclassified (IGCNU, n = 14), seminomas (SEM, n = 107) and non-seminomatous germ cell tumors (NSGCT, n = 42), further subdivided into embryonic carcinomas (EC, n = 30), yolk sac tumors (YST, n = 5), chorionic carcinomas (CC, n = 5) and teratomas (TER, n = 2). Quantification of MED15 protein expression was performed through IHC followed by semi-quantitative image analysis using the Definiens software. In tumor-free seminiferous tubules, MED15 protein expression was absent or only low expressed in spermatogonia. Interestingly, the precursor lesions IGCNU exhibited heterogeneous but partly very strong MED15 expression. SEM weakly express the Mediator complex subunit MED15, whereas NSGCT and especially EC show significantly enhanced expression compared to tumor-free testis. In conclusion, MED15 is differentially expressed in tumor-free testis and TGCT. While MED15 is absent or low in tumor-free testis and SEM, NSGCT highly express MED15, hinting at the diagnostic potential of this marker to distinguish between SEM and NSGCT. Further, the precursor lesion IGCNU showed increased nuclear MED15

    Testicular cancer is the most common cancer in men aged between 15 and 35 and more than 90% of testicular neoplasms are originated at germ cells. Recent research has shown the impact of microRNAs (miRNAs) in different types of cancer, including testicular germ cell tumor (TGCT). MicroRNAs are small non-coding RNAs which affect the development and progression of cancer cells by binding to mRNAs and regulating their expressions. The identification of functional miRNA-mRNA interactions in cancers, i.e. those that alter the expression of genes in cancer cells, can help delineate post-regulatory mechanisms and may lead to new treatments to control the progression of cancer. A number of sequence-based methods have been developed to predict miRNA-mRNA interactions based on the complementarity of sequences. While necessary, sequence complementarity is, however, not sufficient for presence of functional interactions. Alternative methods have thus been developed to refine the sequence-based interactions using concurrent expression profiles of miRNAs and mRNAs. This study aims to find functional cancer-specific miRNA-mRNA interactions in TGCT. To this end, the sequence-based predicted interactions are first refined using an ensemble learning method, based on two well-known methods of learning miRNA-mRNA interactions, namely, TaLasso and GenMiR++. Additional functional analyses were then used to identify a subset of interactions to be most likely functional and specific to TGCT. The final list of 13 miRNA-mRNA interactions can be potential targets for identifying TGCT-specific interactions and future laboratory experiments to develop new therapies.

    To evaluate the results of testis-sparing surgery (TSS) in patients, with small testicular lesions and a normal contralateral testicle. In all, 28 patients were treated with TSS for small testicular lesions and a normal contralateral testicle. TSS was considered in patients with testicular lesions smaller than 2 cm and no evidence of metastatic disease. The mean age of patients was 35.3 ± 7.3 years, while the mean diameter of the testicular lesions was 11.4 ± 3.7 mm. After pathological examination, 18 patients (64.3%) were diagnosed with stromal tumors and miscellaneous lesions, while 10 (35.7%) had a germ cell tumor. The median follow-up time for the former group was 33 months and no recurrences were observed. In one patient with germ cell tumor, immediate orchiectomy was performed, while the remaining nine were followed-up (median time, 45 months). One patient developed local recurrence after 39 months. Excellent outcomes for benign lesions could be achieved using TSS. TSS could be offered safely in highly selected patients with germ cell tumors, specifically within a clinical trial but there is more data needed regarding the potential risks and benefits. J. Surg.

    Direct measurements using TLD dosimeters permitted to calculate radiation doses delivered to the testes in radiotherapy for supradiaphragmatic forms of Hodgkin's disease, stages I and II; they were found to constitute from 1 to 2% of focal dose, that is, to amount to 40-80 cGy given in 20 nonuniform fractions. In radiotherapy for subdiaphragmatic forms of the disease, the dose to the testes varied from 360 to 400 cGy. Anthropomorphic, phantom measurements with ionization chambers placed within the phantom testes showed contributions to total testicular dose to vary with individual irradiation fields in these cases. Thus, for instance, 82% of total dose was due to irradiation of both iliac fields; shielding of the testes with lead caps (5mm) reduced this irradiation to one-half. Doses to the testes were relatively large in radiotherapy for testicular tumors (seminomas and teratocarcinomas). By combining radiotherapy with chemotherapy or surgical intervention, permanent cure or long-lasting remissions may be achieved in most cases. In this connection, there arises the question as to the potential risk of patients - mostly young males with maintained reproductive capacity - transmitting radiation - induced genetic damage to their progeny. An attempt was made to appraise such genetic risk from additional above-background exposure. (authors)

    Full Text Available Background: Experimental unilateral cryptorchidism (ULC and bilateral cryptorchidism (BLC are excellent methods to study undescended testis in relation to spermatogenesis against a temperature gradient. Objectives: In case of ULC, it is possible to compare the testicular functions between normal condition and cryptorchidism in the same animal, whereas BLC shows the necessity of testicular androgens for proper maintenance of reproductive structures and functions. Materials and Methods: In the present study, experimental ULC and BLC was done on same-aged adult mature male mice and kept for 15 days and 30 days, respectively, to observe the changes due to the induced cryptorchidism on the different reproductive organs, viz., the testis and accessory sex organs along with epididymal sperm count. Reproductive tissues were collected from individual animals and histopathological studies of testis were done to investigate different cytological changes. Results: The size of the testes and accessory sex organs were found to be significantly reduced in BLC mice, whereas only testicular weight reduction was observed in ULC mice. Histopathological studies showed degenerative changes throughout the seminiferous tubules. Conclusion: Thus, the present investigation showed compensatory androgen production in ULC mice, whereas absence of androgen mediated reproductive functions in BLC animals.

    Full Text Available PurposeIn male patients with congenital adrenal hyperplasia (CAH, the presence of testicular adrenal rest tumors (TARTs have been reported, however their prevalence and clinical manifestations are not well known. Untreated TARTs may lead to testicular structural damage and infertility. This study was conducted to investigate the prevalence of TARTs in male patients with CAH, and characterize the manifestations to identify contributing factors to TART.MethodsAmong 102 CAH patients aged 0-30 years, 24 male patients have been regularly followed up in our outpatient clinic at Severance Children's Hospital from January 2000 to December 2014. In order to reveiw the characteristics of TART patients, we calculated the mean levels of hormones during the 5 years before the time of investigation. Five patients underwent follow-up scrotal ultrasonography (US after adjusting the dosage of glucocorticoids.ResultsTARTs were detected in 8 of the 13 patients (61.5%. The median age of TARTs diagnosis was 20.2 years with the youngest case being 15.5 years old. The mean serum level of adrenocorticotropic hormone (ACTH was higher in the TARTs patient group compared to the non-TARTs group (P<0.05. The tumor size decreased in 3 cases, slightly increased in 1 case, and had no change in another case.ConclusionThe serum ACTH level might be associated with the growth promoting factor for TARTs, but the exact mechanism has not been clearly identified. Screening for TARTs using US is important in male patients with CAH for early-detection and prevention of ongoing complications, such as infertility.

    Testicular germ cell tumors (TGCT) that arise in young men are composed of two histologic types, seminomas and nonseminomas. Risk patterns for the two types appear to be similar and may be related to either endogenous or exogenous hormonal exposures in utero. Why similar risk patterns would result in different histologic types is unclear, but could be related to varying genetic susceptibility profiles. Genetic variation in hormone metabolizing genes could potentially modify hormonal exposures, and thereby affect which histologic type a man develops. To examine this hypothesis, 33 single nucleotide polymorphisms (SNPs) in four hormone metabolism candidate genes (CYP1A1, CYP17A1, HSD17B1, HSD17B4) and the androgen receptor gene (AR) were genotyped. Associations with TGCT were evaluated among 577 TGCT cases (254 seminoma, 323 nonseminoma) and 707 controls from the US Servicemen's Testicular Tumor Environmental and Endocrine Determinants (STEED) study. There were no significant associations with TGCT overall based on a test using an additive model. However, compared to homozygotes of the most common allele, two nonredundant SNPs in CYP1A1 were inversely associated with nonseminoma: CYP1A1 promoter SNP rs4886605 OR = 0.75 (95% CI = 0.54-1.04) among the heterozygotes and OR = 0.37, 95% CI = 0.12-1.11 among the homozygotes with a p-value for trend = 0.02; rs2606345 intron 1 SNP, OR = 0.69 (95% CI = 0.51-0.93) among heterozygotes and OR = 0.70 (95% CI = 0.42-1.17) among homozygotes, with a p-value for trend = 0.02. Caution in interpretation is warranted until findings are replicated in other studies; however, the results suggest that genetic variation in CYP1A1 may be associated with nonseminoma.

    Despite a good prognosis, the typically young age at diagnosis and physical sequelae may cause psychological distress in germ cell tumor survivors. We aimed to determine the frequency of anxiety and depression and analyze the impact of demographic and disease-related factors. We enrolled N=164 testicular germ cell tumor survivors receiving routine follow-up care at the University Cancer Center Hamburg and a specialized private practice (mean, 11.6 years after diagnosis). Patients completed the Generalized Anxiety Disorder Screener-7, the Patient Health Questionnaire-9 and the Memorial Symptom Assessment Scale-Short Form. We found clinically significant anxiety present in 6.1% and depression present in 7.9% of survivors. A higher number of physical symptoms and having children were significantly associated with higher levels of both anxiety and depression in multivariate regression analyses controlling for age at diagnosis, cohabitation, socioeconomic status, time since diagnosis, metastatic disease and relapse. Younger age at diagnosis and shorter time since diagnosis were significantly associated with higher anxiety. Although rates of clinically relevant anxiety and depression were comparably low, attention toward persisting physical symptoms and psychosocial needs related to a young age at diagnosis and having children will contribute to address potential long-term psychological distress in germ cell tumor survivors.

    Objective To provide guidelines for future trials, we reviewed the outcomes of children with synchronous bilateral Wilms tumors (BWT) treated on National Wilms Tumor Study-4 (NWTS-4). Methods NWTS-4 enrolled 3,335 patients (pts) including 188 pts with BWT (5.6%). Treatment and outcome data were collected. Results Among 188 BWT pts registered with NWTS-4, 195 kidneys in 123 patients had initial open biopsy, 44 kidneys in 31 pts had needle biopsies. Although pre-resection chemotherapy was recommended, 87 kidneys in 83 pts were managed with primary resection: Complete nephrectomy 48 in 48 pts, 31 partial/wedge nephrectomies in 27 pts, enucleations 8 in 8 pts. No initial surgery was performed in 45 kidneys in 43 pts, 5 kidneys in 3 pts not coded. Anaplasia was diagnosed after completion of the initial course of chemotherapy in 14 pts (initial surgical procedure: 9 open biopsies, 4 needle biopsies, 1 partial nephrectomy). The average number of days from the start of chemotherapy to diagnosis of anaplasia was 390 (range 44–1,925 days). Relapse or progression of disease occurred in 54 children. End stage renal failure occurred in 23 children, 6 of whom had bilateral nephrectomies. The 8 year event free survival (EFS) for BWT with favorable histology was 74%, and overall survival (OS) was 89%; while the EFS for BWT with unfavorable histology was 40%, OS was 45%. Conclusion The current analysis of patients with BWT treated on NWTS-4 shows that preservation of renal parenchyma is possible in many pts following initial preoperative chemotherapy. The incidence of end-stage renal disease remains significantly higher in children with BWT. Future studies are warranted to address the need for earlier biopsy in non-responsive tumors and earlier definitive surgery to recognize unfavorable histology in these high risk patients.

    Full Text Available Young males have testicular germ cells tumours (TGCT as the most common malignancy and its incidence is increasing in several countries. Besides unilateral orchiectomy (UO, the treatment of TGCT may include surveillance, radiotherapy or chemotherapy (CT, basing on tumour histology and stage of disease. It is well known that both radio and CT may have negative effects on testicular function, affecting spermatogenesis and sex hormones. Many reports investigated these aspects in patients treated with bleomycin, etoposide and cisplatin (BEP, after UO. In contrast no data are available on the side effects of carboplatin treatment in these patients. We included in this study 212 consecutive subjects who undergone to sperm banking at our Andrology and Human Reproduction Unit after UO for TGCT. Hundred subjects were further treated with one or more BEP cycles (BEP-group, 54 with carboplatin (Carb group and 58 were just surveilled (S-group. All patients were evaluated for seminal parameters, sperm aneuploidy, sperm DNA, sex hormones, volume of the residual testis at baseline (T0 and after 12 (T1 and 24 months (T2 from UO or end of CT. Seminal parameters, sperm aneuploidies, DNA status, gonadic hormones and testicular volume at baseline were not different between groups. At T1 we observed a significant reduction of sperm concentration and sperm count in the BEP group versus baseline and versus both Carb and S- group. A significant increase of sperm aneuploidies was present at T1 in the BEP group. Similarly, the same group at 1 had altered sperm DNA integrity and fragmentation compared with baseline, S group and Carb group. These alterations were persistent after two years from the end of BEP treatment. Despite a slight improvement at T2, the BEP group had still higher percentages of sperm aneuploidies than other groups. No impairment of sperm aneuploidies and DNA status were observed in the Carb group both after one and two years from the end of treatment

    Two hundred patients with testicular tumor were examined by computed tomography (CT), lymphography, and phlebography of the inferior vena cava and left renal and testicular veins. Metastases were demonstrated in 71. CT was positive in 66, lymphography in 60, phlebography in 53, and a combination of lymphography and phlebography in 65. CT was particularly helpful in studying the upper retroperitoneal space and defining the extent of tumor. Lymphography was preferable for demonstrating metastases in non-enlarged, contrastfilled nodes. Phlebography was never the only positive examination and is not recommended as a routine procedure, though it may be helpful in planning surgery. The authors suggest that CT be performed first, followed by lymphography in negative or equivocal cases

    Testicular adrenal rest tumors (TARTs) are secondary to hypertrophy of adrenal rest cells in the rete testis in settings of hypersecretion of androgens. We present a case of congenital adrenal hyperplasia with TART with clues to the diagnosis on 18 F-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT). To the best of our knowledge, this is the first reported case on the role of 18 F-FDG PET/CT in TART.

    Retained fetal expression of angiotensin I-converting enzyme (ACE, CD143) has recently been shown in intratubular germ cell neoplasms (IGCN) and invasive germ cell tumors (GCT), suggesting the somatic isoform (sACE) as a characteristic component of neoplastic germ cells. We analyzed the distribution of sACE in 159 testicular GCT, including 87 IGCN. sACE protein was determined by immunohistochemistry (MAb CG2) on routinely formalin-fixed and paraffin-embedded tissue sections, supplemented by mRNA expression analysis using in situ hybridization. These data were compared with those obtained by germ cell/placental alkaline phosphatases (PIAP; MAbs PL8-F6 and 8A9) employing an uniform score system for the evaluation of immunoreactivity (IRS; possible values from 0 to 12). Expression of sACE and PIAP was found in all 87 analyzed IGCN (IRS > 4, median IRS of 12). Heterogeneous staining patterns were not related to the type of adjacent GCT but correlated with low expression in adjacent seminomas (P =.032 for sACE; P =.005 for PIAP). Both sACE and PIAP often showed a decreased and more heterogeneous but still moderate expression in 91 classic seminomas (median IRS of 8) and were completely absent in tumor cells of spermatocytic seminomas. Despite all similarities, we found sACE and PIAP differently regulated during GCT progression. This was documented by a well-preserved expression of either sACE or PIAP or both in all classic seminomas, low PIAP immunoreactivity in metastasis of seminomas, and completely diverging expression patterns in nonseminomatous GCT. Our findings underline the close molecular relationship between IGCN and seminoma, and suggest sACE as an appropriate marker for seminomatous differentiated tumors. HUM PATHOL 31:1466-1476.

  8. Significant calendar period deviations in testicular germ cell tumors indicate that postnatal exposures are etiologically relevant.

    The current working model of type II testicular germ cell tumor (TGCT) pathogenesis states that carcinoma in situ arises during embryogenesis, is a necessary precursor, and always progresses to cancer. An implicit condition of this model is that only in utero exposures affect the development of TGCT in later life. In an age-period-cohort analysis, this working model contends an absence of calendar period deviations. We tested this contention using data from the SEER registries of the United States. We assessed age-period-cohort models of TGCTs, seminomas, and nonseminomas for the period 1973-2008. Analyses were restricted to whites diagnosed at ages 15-74 years. We tested whether calendar period deviations were significant in TGCT incidence trends adjusted for age deviations and cohort effects. This analysis included 32,250 TGCTs (18,475 seminomas and 13,775 nonseminomas). Seminoma incidence trends have increased with an average annual percentage change in log-linear rates (net drift) of 1.25 %, relative to just 0.14 % for nonseminoma. In more recent time periods, TGCT incidence trends have plateaued and then undergone a slight decrease. Calendar period deviations were highly statistically significant in models of TGCT (p = 1.24(-9)) and seminoma (p = 3.99(-14)), after adjustment for age deviations and cohort effects; results for nonseminoma (p = 0.02) indicated that the effects of calendar period were much more muted. Calendar period deviations play a significant role in incidence trends of TGCT, which indicates that postnatal exposures are etiologically relevant.

    Five patients with disseminated non-seminomatous testicular germ cell tumors are described. These patients have been clinically free of disease for 25 to more than 99 months and may be cured, since the interval after last treatment ranges from 13 to more than 76 months. Two patients, including 1 with pure choriocarcinoma, represent chemotherapeutic successes. In 3 patients the advantages of an individualized, multidisciplinary approach with surgery, radiotherapy and chemotherapy are shown. The benefits of continued aggressive treatment using residual therapeutic modalities despite prior failure with other therapy are documented.

    Full Text Available Introduction: Risk of testicular germ cell tumors (TGCT is consistently associated with a history of cryptorchidism (CO in epidemiologic studies. Factors modifying the association may provide insights regarding etiology of TGCT and suggest a basis for individualized care of CO. To identify modifiers of the CO-TGCT association, we conducted a comprehensive, quantitative evaluation of epidemiologic data.Materials and Methods: Human studies cited in PubMed or ISI Web of Science indices through December 2011 and selected unpublished epidemiologic data were reviewed to identify 35 articles and one unpublished dataset with high-quality data on the CO-TGCT association. Association data were extracted as point and 95% confidence interval estimates of odds ratio (OR or standardized incidence ratio (SIR, or as tabulated data. Values were recorded for each study population, and for subgroups defined by features of study design, CO and TGCT. Extracted data were used to estimate summary risk ratios (sRR and evaluate heterogeneity of the CO-TGCT association between subgroups.Results: The overall meta-analysis showed that history of CO is associated with four-fold increased TGCT risk (RR=4.1(95%CI=3.6-4.7. Subgroup analyses identified five determinants of stronger association: bilateral CO, unilateral CO ipsilateral to TGCT, delayed CO treatment, TGCT diagnosed before 1970, and seminoma histology. Conclusions: Modifying factors may provide insight into TGCT etiology and suggest improved approaches to managing CO. Based on available data, cryptorchidism patients and their parents or caregivers should be made aware of elevated TGCT risk following orchidopexy, regardless of age at repair, unilateral versus bilateral nondescent, or position of undescended testes.

  13. Risk stratification for venous thromboembolism in patients with testicular germ cell tumors.

    Full Text Available Patients with testicular germ cell tumors (TGCT have an increased risk for venous thromboembolism (VTE. We identified risk factors for VTE in this patient cohort and developed a clinical risk model.In this retrospective cohort study at the Medical University of Graz we included 657 consecutive TGCT patients across all clinical stages. A predictive model for VTE was developed and externally validated in 349 TGCT patients treated at the University Hospital Zurich.Venous thromboembolic events occurred in 34 (5.2% patients in the Graz cohort. In univariable competing risk analysis, higher clinical stage (cS and a retroperitoneal lymphadenopathy (RPLN were the strongest predictors of VTE (p<0.0001. As the presence of a RPLN with more than 5cm in greatest dimension without coexisting visceral metastases is classified as cS IIC, we constructed an empirical VTE risk model with the following four categories (12-month-cumulative incidence: cS IA-B 8/463 patients (1.7%, cS IS-IIB 5/86 patients (5.9%, cS IIC 3/21 patients (14.3% and cS IIIA-C 15/70 patients (21.4%. This risk model was externally validated in the Zurich cohort (12-month-cumulative incidence: cS IA-B (0.5%, cS IS-IIB (6.0%, cS IIC (11.1% and cS IIIA-C (19.1%. Our model had a significantly higher discriminatory performance than a previously published classifier (RPLN-VTE-risk-classifier which is based on the size of RPLN alone (AUC-ROC: 0.75 vs. 0.63, p = 0.007.According to our risk stratification, TGCT patients with cS IIC and cS III disease have a very high risk of VTE and may benefit from primary thromboprophylaxis for the duration of chemotherapy.

    Juvenile granulosa cell tumor (JGCT) of the testis is a rare benign tumor that typically presents as a relatively small (<2 cm) unilateral scrotal mass in neonates or infants. Bilateral JGCT of the testes presenting as large intraabdominal masses in the neonate is very rare. Utilizing preoperative MRI findings, we report a rare case of bilateral JGCT of the testes presenting as large multiseptated abdominal masses originating from undescended intraabdominal testes in a neonate.

  17. Tiling array-CGH for the assessment of genomic similarities among synchronous unilateral and bilateral invasive breast cancer tumor pairs

    Full Text Available Abstract Background Today, no objective criteria exist to differentiate between individual primary tumors and intra- or intermammary dissemination respectively, in patients diagnosed with two or more synchronous breast cancers. To elucidate whether these tumors most likely arise through clonal expansion, or whether they represent individual primary tumors is of tumor biological interest and may have clinical implications. In this respect, high resolution genomic profiling may provide a more reliable approach than conventional histopathological and tumor biological factors. Methods 32 K tiling microarray-based comparative genomic hybridization (aCGH was used to explore the genomic similarities among synchronous unilateral and bilateral invasive breast cancer tumor pairs, and was compared with histopathological and tumor biological parameters. Results Based on global copy number profiles and unsupervised hierarchical clustering, five of ten (p = 1.9 × 10-5 unilateral tumor pairs displayed similar genomic profiles within the pair, while only one of eight bilateral tumor pairs (p = 0.29 displayed pair-wise genomic similarities. DNA index, histological type and presence of vessel invasion correlated with the genomic analyses. Conclusion Synchronous unilateral tumor pairs are often genomically similar, while synchronous bilateral tumors most often represent individual primary tumors. However, two independent unilateral primary tumors can develop synchronously and contralateral tumor spread can occur. The presence of an intraductal component is not informative when establishing the independence of two tumors, while vessel invasion, the presence of which was found in clustering tumor pairs but not in tumor pairs that did not cluster together, supports the clustering outcome. Our data suggest that genomically similar unilateral tumor pairs may represent a more aggressive disease that requires the addition of more severe treatment modalities, and

    Genome-wide association studies (GWAS) have transformed understanding of susceptibility to testicular germ cell tumors (TGCTs), but much of the heritability remains unexplained. Here we report a new GWAS, a meta-analysis with previous GWAS and a replication series, totaling 7,319 TGCT cases and 23,082 controls. We identify 19 new TGCT risk loci, roughly doubling the number of known TGCT risk loci to 44. By performing in situ Hi-C in TGCT cells, we provide evidence for a network of physical interactions among all 44 TGCT risk SNPs and candidate causal genes. Our findings implicate widespread disruption of developmental transcriptional regulators as a basis of TGCT susceptibility, consistent with failed primordial germ cell differentiation as an initiating step in oncogenesis. Defective microtubule assembly and dysregulation of KIT-MAPK signaling also feature as recurrently disrupted pathways. Our findings support a polygenic model of risk and provide insight into the biological basis of TGCT.

  2. Dissecting Time- from Tumor-Related Gene Expression Variability in Bilateral Breast Cancer

    Full Text Available Metachronous (MBC and synchronous bilateral breast tumors (SBC are mostly distinct primaries, whereas paired primaries and their local recurrences (LRC share a common origin. Intra-pair gene expression variability in MBC, SBC, and LRC derives from time/tumor microenvironment-related and tumor genetic background-related factors and pairs represents an ideal model for trying to dissect tumor-related from microenvironment-related variability. Pairs of tumors derived from women with SBC (n = 18, MBC (n = 11, and LRC (n = 10 undergoing local-regional treatment were profiled for gene expression; similarity between pairs was measured using an intraclass correlation coefficient (ICC computed for each gene and compared using analysis of variance (ANOVA. When considering biologically unselected genes, the highest correlations were found for primaries and paired LRC, and the lowest for MBC pairs. By instead limiting the analysis to the breast cancer intrinsic genes, correlations between primaries and paired LRC were enhanced, while lower similarities were observed for SBC and MBC. Focusing on stromal-related genes, the ICC values decreased for MBC and were significantly different from SBC. These findings indicate that it is possible to dissect intra-pair gene expression variability into components that are associated with genetic origin or with time and microenvironment by using specific gene subsets.

    To assess the values of parameters derived from whole-lesion histograms of the apparent diffusion coefficient (ADC) at 3T for the characterization of testicular germ cell tumors (TGCTs). A total of 24 men with TGCTs underwent 3T diffusion-weighted imaging. Fourteen tumors were pathologically confirmed as seminomas, and ten tumors were pathologically confirmed as nonseminomas. Whole-lesion histogram analysis of the ADC values was performed. A Mann-Whitney U test was employed to compare the differences in ADC histogram parameters between seminomas and nonseminomas. Receiver operating characteristic analysis was used to identify the cutoff values for each parameter for differentiating seminomas from nonseminomas; furthermore, the area under the curve (AUC) was calculated to evaluate the diagnostic accuracy. The median of 10th, 25th, 50th, 75th, and 90th percentiles and mean, minimum and maximum ADC values were all significantly reduced for seminomas compared with nonseminomas (phistogram analysis of ADCs might be used for preoperative characterization of TGCTs.

    The prospective study, carried out from February 1992 to January 1996, included 49 patients in clinical Stage I nonseminomatous germ cell testicular tumors (NSGCTT). They are aged 16-40 years (mean, 25 years). Patients were stratified to different risk-adapted therapeutic approaches according to histopathologic findings of primary tumor removed by inguinal orchiectomy. Eleven patients of the first group with vascular invasion and majority of embryonal carcinoma components in the primary tumor were treated with adjuvant chemotherapy (2 cycles of BEP). None of them had disease progression after the follow-up of 4-43+ months (mean, 20.9 months) after orchiectomy. Five patients of the second group with vascular invasion and majority of teratoma elements in the primary tumor were treated with primary retroperitoneal lymph node dissection (RPLND). They were followed-up 29-445+ months (mean, 33.4 months) after orchiectomy. Two of them (40%) had pathologic Stage II after RPLND and underwent subsequent BEP chemotherapy. One of them died due to disease progression in disseminated stage 29 months after orchiectomy. The second on lives with no evidence of the disease (NED). Thirty three patients in the third group without vascular invasion were kept under surveillance. They were followed-up 3-48+ months (mean, 22.3 months) after orchiectomy. Disease progression was observed in 5 of them (15.1%), 7-10 months (mean, 8.8 months) following orchiectomy. These patients were treated with BEP chemotherapy and live with NED 1-16+ months (mean, 9.2 months) after completion of the therapy. The overall survival rate in clinical Stage I patients was 97.9%. The authors recommend the surveillance policy only in clinical Stage NSGCTT patients without vascular invasion in the primary tumor. (author)

    Sex cord-stromal tumors (SCSTs) are the second most frequent category of testicular neoplasms, accounting for approximately 2% to 5% of cases. Both genetic and epigenetic factors account for the differences in frequency and histologic composition between testicular and ovarian SCSTs. For example, large cell calcifying Sertoli cell tumor and intratubular large cell hyalinizing Sertoli cell neoplasia occur in the testis but have not been described in the ovary. In this article, we discuss recently described diagnostic entities as well as inconsistencies in nomenclature used in the recent World Health Organization classifications of SCSTs in the testis and ovary. We also thoroughly review the topic of neoplasms composed of both germ cells and sex cord derivatives with an emphasis on controversial aspects. These include "dissecting gonadoblastoma" and testicular mixed germ cell-sex cord stromal tumor (MGC-SCST). The former is a recently described variant of gonadoblastoma that sometimes is an immediate precursor of germinoma in the dysgenetic gonads of patients with a disorder of sex development. Although the relationship of dissecting gonadoblastoma to the previously described undifferentiated gonadal tissue is complex and not entirely resolved, we believe that it is preferable to continue to use the term undifferentiated gonadal tissue for those cases that are not neoplastic and are considered to be the precursor of classical gonadoblastoma. Although the existence of testicular MGC-SCST has been challenged, the most recent evidence supports its existence; however, testicular MGC-SCST differs significantly from ovarian examples due to both genetic and epigenetic factors.

    Carotid body tumors are rare, highly vascularized neoplasms that arise from the paraganglia located at the carotid bifurcation. Surgery is the only curative treatment. However, treatment of bilateral carotid body tumors represents a special challenge due to potential neurovascular complications. We present the therapeutic management of a 34-year-old woman with bilateral carotid body tumors. The patient underwent surgical resection of the largest tumor. It was not possible to resect the tumor without sacrificing the ipsilateral vagal nerve. Due to unilateral vagal palsy, we decide to withhold all invasive therapy and to observe contralateral tumor growth with serial imaging studies. The patient is free of disease progression 5 years later. Treatment of bilateral CBTs should focus on preservation of the quality of life rather than on cure of the disease. In patients with previous contralateral vagal palsies, the choice between surgery and watchful waiting is a balance between the natural potential morbidity and the predictable surgical morbidity. Therefore, to avoid bilateral cranial nerve deficits, these patients may be observed until tumor growth is determined, and, if needed, treated by radiation therapy.

A male zebra finch was presented because of white diarrhea, anorexia, loss of weight and lethargy. At necropsy, the small intestine was edematous and congested. The spleen appeared pale. The liver was large, firm and brown. One testis was cystic and neoplastic and the remaining testis was atrophic. Histologically, amyloid materials were seen predominantly in the liver and spleen. Hyaline substances were deposited in the Disse space and in the media of blood vessels of the liver. In spleen, marked deposits thickened the basement membranes of blood vessels and extended into the surrounding parenchyma. In addition, there were lesser degrees of amyloidosis in other organs such as small intestine. Amyloid stained positively with Congo red. In testis, there was encapsulated unilateral interstitial cell tumor, with multiple foci of necrosis and hemorrhage. The neoplastic cells were round to polyhedral, with small round hyperchromatic nuclei and finely vacuolated cytoplasm. Signs of feminization were observed. The cause of amyloidosis in this study was not conclusively identified.

    Testicular germ cell tumors (TGCTs) are the most frequent malignances in young adult men. The two main histological forms, seminomas and nonseminomas, differ biologically and clinically. pRB protein and its immediate upstream regulator p16INK4a are involved in the RB pathway which is deregulated in most TGCTs. The objective of this study was to evaluate the occurrence of loss of heterozygosity (LOH) of the CDKN2A (p16INK4a) and RB1 tumor suppressor genes in TGCTs. Forty TGCTs (18 seminomas and 22 nonseminomas) were analyzed by polymerase chain reaction using the restriction fragment length polymorphism or the nucleotide repeat polymorphism method. LOH of the CDKN2A was found in two (6%) out of 34 (85%) informative cases of our total TGCT sample. The observed changes were assigned to two (11%) nonseminomas out of 18 (82%) informative samples. Furthermore, LOH of the RB1 was detected in two (6%) out of 34 (85%) informative cases of our total TGCT sample. Once again, the observed changes were assigned to two (10.5%) nonseminomas out of 19 (86%) informative samples. Both LOHs of the CDKN2A were found in nonseminomas with a yolk sac tumor component, and both LOHs of the RB1 were found in nonseminomas with an embryonal carcinoma component. The higher incidence of observed LOH in nonseminomas may provide a clue to their invasive behavior

    Juvenile granulosa cell tumor of the testis of neonates and infants is an uncommon lesion frequently associated with abnormal sex chromosome and ambiguous genitalia. This report describes a juvenile granulosa cell tumor arising in the testis of a neonate. Chromosome analysis of the tumor showed a normal male karyotype 46 XY. Histopathology and immunohistochemical studies revealed the occurrence of 2 well-differentiated epithelial-like and smooth muscle-like components in the neoplasm. The morphologic clues leading to the correct diagnosis of juvenile granulosa cell tumor and the possible histogenesis are briefly discussed.

    Gamma camera imaging of the adrenal glands was done in 8 dogs with hyperadrenocorticism and 4 normal dogs given intravenous injections of 131I-19-iodocholesterol. In normal dogs, both adrenal glands could be visualized separately, and there was no difficulty in distinguishing among the images of normal glands, hyperplastic glands, and functional adrenal tumors. In addition, gamma camera imaging enabled the correct surgical site to be selected for removal of adrenal tumors. Hyperadrenocorticism was diagnosed in 8 dogs by evaluation of urinary 17-hydroxycorticosteroid (OHCS) excretion rates, urinary 17-OHCS and plasma 11 beta-OHCS responses to dexamethasone suppression of endogenous adrenocorticotropin (ACTH) secretion, and plasma 11 beta-OHCS response to intravenous administration of ACTH. Base line 17-OHCS excretion increased in 5 of the 8 dogs. Plasma 11 beta-OHCS concentrations were not decreased by dexamethasone administration in the 4 dogs subsequently found to have adrenal tumors; however, there was an exaggerated increase in plasma 11 beta-OHCS concentration after administration of ACTH in 3 of the 4 dogs which had bilateral adrenocortical hyperplasia

    Purpose To perform a systematic literature review to assess whether the occurrence of testicular microlithiasis (TML) in conjunction with other risk factors is associated with testicular cancer. Methods A systematic literature search was performed of original articles in English published 1998...... In total, 282 abstracts in were identified. Based on title and abstract the eligibility was assessed and 31 studies were included. Five conditions in relation to TML and testicular cancer emerged: Down syndrome, McCune–Albright syndrome, cryptorchidism, infertility and familial disposition of testicular...... cancer. Conclusion Data support the conclusion that TML is not an independent risk factor for testicular cancer but associated with testicular cancer through other conditions. In male infertility, TML appears to be related to an increased risk of testicular cancer possibly as part of a testicular...

    Purpose: To evaluate qualitative, semi-quantitative, and quantitative parameters obtained by dynamic contrast-enhanced (DCE)-MRI for the characterization of histologically proven, non-palpable, incidentally found intratesticular tumors. Materials and methods: From 2006 to 2014, we included men with non-palpable, incidentally found testicular tumors on ultrasound, normal tumoral marker levels,referred for surgery. DCE-MRI data were analyzed retrospectively and independently by two radiologists blinded to the histological diagnosis. The visual enhancement patterns, time-signal intensity curves, shape of the curves (type 0–3), maximal relative enhancement (Peak), initial enhancement slope (IS), time to peak (TTP), as well as transfer constants Ktrans and Kep were compared between the tumors. The interobserver correlation was evaluated. Receiver Operating Characteristic (ROC) curves and areas under the curve (AUC) were extracted. Results: Thirty-one patients (mean age of 37.3 years) were included. Tumor mean size was 1.2 ± 0.77 cm (min = 0.3 cm, max = 2.8 cm). Regarding the histology results, three groups were defined: Twelve stromal “benign tumors” (BT) exhibited more type 2 and type 3 curves than 12 “malignant tumors” (MT) and 7 “burned-out tumors” (BOT) (p < 0.0001). BT had a higher peak (96 vs. 54 and 17%), shorter TTP (215 vs. 412 and 692 sec), higher IS (73 vs. 12 and 2 arbitrary units), higher Ktrans (255 vs. 88 and 14 min −1 *1000) and higher Kep (554 vs. 159 and 48 min −1 *1000) than MT and BOT, respectively (p < 0.0001, p = 0.0003, p < 0.0001, p < 0.0001 and p < 0.0001, respectively). The agreement coefficient values and the AUC extracted after gathering MT with BOT varied from 0.83 to 0.96 and from 0.868 to 0.978, respectively. Conclusion: DCE-MRI may assist in differentiating between benign intratesticular stromal tumors,malignant and burned-out tumors.

    Determinations of alpha fetoprotein and chorionic gonadotropin levels by radioimmunoassay in 340 patients with germ cell tumors of the testes have confirmed that tumor markers are suitable prognostic parameters, facilitate assessment of the clinical stage, are sensitive parameters of the efficacy of chemotherapy and enable early detection of relapses. In a group of 71 patients with prostate cancer, systematic determination of prostate specific antigen levels proved to be a reliable method of monitoring and a sensitive method of detecting remote metastases.

    The molecular basis for enhanced chemosensitivity of testicular germ cell tumors (GCT) has been an area of great interest, as it could potentially give us therapeutic leads in other resistant malignancies. Thus far, however, the increased sensitivity of GCT has been variously attributed to multiple factors - an inability to detoxify cisplatin, a lack of export pumps, an inability to repair the DNA damage, an intact apoptotic cascade and lack of p53 mutation; but a unifying underlying etiology leading to the aforementioned processes and having a translational implication has so far been elusive. Herein, we offer evidence to support a potential significant role for the previously demonstrated low hypoxia inducible factor-1α (HIF-1α) expression in mediating the general exquisite chemosensitivity of testicular GCT, through the aforementioned processes. This molecular mechanism based hypothesis could have a significant translational implication in platinum refractory GCT as well as other platinum resistant malignancies.

    Full Text Available Objective: to define predictors that influence longevity in patients with recurrent non-seminomatous germinal testicular tumors (NGTT on standard second-line chemotherapy (CT including cisplatin and iphosphamide. Statistical analysis was performed using the statistical packages Graph Pad Prism 4.00 for Windows and SPSS 15.0 for Windows. Subjects and methods. Case history data were analyzed in 693 patients with disseminated NGTT who had received current CT and followed up at the Department of Clinical Pharmacology and CT, N.N. Blokhin Russian Cancer Research Center, Russian Academy of Medical Sciences. The median follow-up was 32 (range 3-215 months. The disease progressed in 181 (26% patients. Detailed information was available on the nature of second-line CT in only 138 patients. Half (71 (51.7% of the 138 patients had second-line CT including iphosphamide. Uni- and multivariate analyses were made to identify predictors that influence longevity in patients with recurrent NGTT on standard secondline CT including cisplatin and iphosphamide. Results. Five-year overall survival (OS was 32% (95% confidence interval 25-41%. The multivariate analysis showed the morphological pattern of a primary tumor (a yolk sac tumor component, a pre-induction CT lactate dehydrogenase (LDH level of ?d1.5 units of the upper normal range, progression during induction CT, and a pre-second-line CT LDH level of ?d 1000 U/l to be negative predictors. According to the number of negative factors, the patients were classified into 3 groups: 1 good prognosis [n = 10 (14% of the 71 patients], 100% 3-year OS; 2 intermediate prognosis (one negative factor [n = 33 (46.5% of the 71 patients], 50.2% 3-year OS; 3 poor prognosis (?d 2 negative factors, 6.7% 3-year OS.

    Full Text Available We report a case of intra-abdominal testicular tumor in a 36-year-old married lady presenting with chief complaints of primary amenorrhea. The patient was later diagnosed with testicular feminization syndrome, a form of male pseudohermaphroditism. This testicular tumor was histologically proven as seminoma. Due to rarity, imaging findings in patients with testicular feminization syndrome and intraabdominal testicular tumor have been poorly documented. So far, only one case report had described the combined role of CT and MR imaging in intraabdominal testicular sex-cord stromal tumor. To our knowledge, this case is first to document USG and MR imaging in addition to MR spectroscopy features in intraabdominal testicular seminoma.

    Testicular germ cell tumors (TGCT) exhibit striking familial aggregation that remains incompletely explained. To improve the phenotypic definition of familial TGCT (FTGCT), we studied an international cohort of multiple-case TGCT families to determine whether first-degree relatives of FTGCT cases are at increased risk of other types of cancer. We identified 1041 first-degree relatives of TGCT cases in 66 multiple-case TGCT families from Norway and 64 from the United States (combined follow-up of 31,556 person-years). We collected data on all cancers (except nonmelanoma skin cancers) reported by the family informant in these relatives, and we attempted to verify all reported cancer diagnoses through medical or cancer registry records. We calculated observed-to-expected (O/E) standardized incidence ratios, together with 95% confidence intervals (CI), for invasive cancers other than TGCT. We found no increase in risk of cancer overall (Norway O/E = 0.8; 95% CI: 0.6–1.1 and United States O/E = 0.9; 95% CI: 0.7–1.3). Site-specific analyses pooled across the two countries revealed a leukemia excess (O/E = 6.5; 95% CI: 3.0–12.3), deficit of female breast cancer (O/E = 0.0; 95% CI: 0.0–0.6) and increased risk of soft tissue sarcoma (O/E = 7.2; 95% CI: 2.0–18.4); in all instances, these results were based on small case numbers and statistically significant only in Norway. While limited by sample size and potential issues relating to completeness of cancer reporting, this study in multiple-case TGCT families does not support the hypothesis that cancers other than testis cancer contribute to the FTGCT phenotype.

    Testicular germ cell tumors (TGCT) were suggested to have a prenatal environmentally related origin. The potential endocrine disrupting properties of certain solvents may interfere with the male genital development in utero . We aimed to assess the association between maternal and paternal occupational exposures to organic solvents during the prenatal period and TGCT risk in their offspring. This registry-based case control study included TGCT cases aged 14–49 y ( n =8,112) diagnosed from 1978 to 2012 in Finland, Norway, and Sweden. Controls ( n =26,264) were randomly selected from the central population registries and were individually matched to cases on year and country of birth. Occupational histories of parents prior to the child’s birth were extracted from the national censuses. Job codes were converted into solvent exposure using the Nordic job-Nordic Occupational Cancer Study Job-Exposure Matrix. Conditional logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI). Overall, no association was found between prenatal maternal exposure to solvents and TGCT risk. In subset analyses using only mothers for whom occupational information was available in the year of or in the year prior to the child’s birth, there was an association with maternal exposure to aromatic hydrocarbon solvents (ARHC) (OR=1.53; CI: 1.08, 2.17), driven by exposure to toluene (OR=1.67; CI: 1.02, 2.73). No association was seen for any paternal occupational exposure to solvents with the exception of exposure to perchloroethylene in Finland (OR=2.42; CI: 1.32, 4.41). This study suggests a modest increase in TGCT risk associated with maternal prenatal exposure to ARHC. https://doi.org/10.1289/EHP864.

    The formation and removal of four platinum-DNA adducts were immunochemically quantitated in cultured cells derived from a human bladder carcinoma cell line (RT112) and from two lines derived from germ cell tumors of the testis (833K and SUSA), following exposure in vitro to 16.7 microM (5 micrograms/ml) cisplatin. RT112 cells were least sensitive to the drug and were proficient in the repair of all four adducts, whereas SUSA cells, which were 5-fold more sensitive, were deficient in the repair of DNA-DNA intrastrand cross-links in the sequences pApG and pGpG. Despite expressing a similar sensitivity to SUSA cells, 833K cells were proficient in the repair of all four adducts, although less so than the RT112 bladder tumor cells. In addition, SUSA cells were unable to repair DNA-DNA interstrand cross-links whereas 50-85% of these lesions were removed in RT112 and 833K cells 24 h following drug exposure. It is possible that the inability of SuSa cells to repair platinated DNA may account for their hypersensitivity to cisplatin

    Full Text Available The paper describes a clinical case of testicular capillary hemangioma in a 24-year-old man undergone a partial resection of the testis with the intraoperative morphological examination. Testicular capillary hemangioma is a rare benign tumor of a vascular origin, which can be similar to malignant testicular tumors on the clinical presentation, as well as on the imaging methods, in particular to seminoma. The intraoperative histological study can assist in avoiding organ-removing surgical interventions in diagnostically ambiguous cases if a benign testicular tumor is diagnosed.

    Residual tumor resection (RTR) after chemotherapy in patients with advanced germ cell tumors (GCT) is an important part of the multimodal treatment. To provide a complete resection of residual tumor, additional surgical procedures are sometimes necessary. In particular, additional vascular interventions are high-risk procedures that require multidisciplinary planning and adequate resources to optimize outcome. The aim was to identify parameters that predict additional vascular procedures during RTR in GCT patients. A retrospective analysis was performed in 402 GCT patients who underwent 414 RTRs in 9 German Testicular Cancer Study Group (GTCSG) centers. Overall, 339 of 414 RTRs were evaluable with complete perioperative data sets. The RTR database was queried for additional vascular procedures (inferior vena cava [IVC] interventions, aortic prosthesis) and correlated to International Germ Cell Cancer Collaborative Group (IGCCCG) classification and residual tumor volume. In 40 RTRs, major vascular procedures (23 IVC resections with or without prosthesis, 11 partial IVC resections, and 6 aortic prostheses) were performed. In univariate analysis, the necessity of IVC intervention was significantly correlated with IGCCCG (14.1% intermediate/poor vs 4.8% good; p=0.0047) and residual tumor size (3.7% size risk features must initially be identified as high-risk patients for vascular procedures and therefore should be referred to specialized surgical centers with the ad hoc possibility of vascular interventions.

    Human testicular germ cell tumors (TGCT) have a strong genetic component and a high familial relative risk. However, linkage analyses have not identified a rare, highly penetrant familial TGCT (FTGCT) susceptibility locus. Currently, multiple low-penetrance genes are hypothesized to underlie the familial multiple-case phenotype. The observation that two is the most common number of affected individuals per family presents an impediment to FTGCT gene discovery. Clinically, the prospective TGCT risk in the multiple-case family context is unknown. We performed a prospective analysis of TGCT incidence in a cohort of multiple-affected-person families and sporadic-bilateral-case families; 1,260 men from 140 families (10,207 person-years of follow-up) met our inclusion criteria. Age-, gender-, and calendar time-specific standardized incidence ratios (SIR) for TGCT relative to the general population were calculated using SEER*Stat. Eight incident TGCTs occurred during prospective FTGCT cohort follow-up (versus 0.67 expected; SIR = 11.9; 95% CI, 5.1-23.4; excess absolute risk = 7.2/10,000).

    Background Human testicular germ cell tumors (TGCT) have a strong genetic component and a high familial relative risk. However, linkage analyses have not identified a rare, highly-penetrant familial TGCT (FTGCT) susceptibility locus. Currently, multiple low-penetrance genes are hypothesized to underlie the familial multiple-case phenotype. The observation that two is the most common number of affected individuals per family presents an impediment to FTGCT gene discovery. Clinically, the prospective TGCT risk in the multiple-case family context is unknown. Methods We performed a prospective analysis of TGCT incidence in a cohort of multiple-affected-person families and sporadic-bilateral-case families; 1,260 men from 140 families (10,207 person-years of follow-up) met our inclusion criteria. Age-, gender-, and calendar time-specific standardized incidence ratios (SIR) for TGCT relative to the general population were calculated using SEER*Stat. Results Eight incident TGCTs occurred during prospective FTGCT cohort follow-up (versus 0.67 expected; SIR=11.9; 95% confidence interval [CI]=5.1–23.4; excess absolute risk=7.2/10,000). We demonstrate that the incidence rate of TGCT is greater among bloodline male relatives from multiple-case testicular cancer families than that expected in the general population, a pattern characteristic of adult-onset Mendelian cancer susceptibility disorders. Two of these incident TGCTs occurred in relatives of sporadic-bilateral cases (0.15 expected; SIR=13.4; 95%CI=1.6–48.6). Conclusions Our data are the first indicating that despite relatively low numbers of affected individuals per family, members of both multiple-affected-person FTGCT families and sporadic-bilateral TGCT families comprise high-risk groups for incident testicular cancer.

    Testicular cancer is the most common form of solid cancer in young men. Testicular cancer is represented by testicular germ cell tumors (TGCTs) derived from embryonic stem cells with different degrees of differentiation in about 95% of cases. The development of these tumors is related to the formation of a pool of male germ cells and gametogenesis. Clinical factors that are predisposed to the development of germ-cell tumors include cryptorchidism and testicular microlithiasis, as well as infertility associated with the gr/gr deletion within the AZFс locus. KITLG, SPRY4, and BAK1 genes affect the development of the testes and gametogenesis; mutations and polymorphisms of these genes lead to a significant increase in the risk of the TGCT development. To determine the relationship between gene polymorphisms and the development of TGCTs, we developed a system for detection and studied the allele and genotype frequencies of the KITLG (rs995030, rs1508595), SPRY4 (rs4624820, rs6897876), and BAK1 (rs210138) genes in fertile men, patients with TGCTs, and patients with infertility that have the AZFс deletion. A significant association of rs995030 of the KITLG gene with the development of TGCTs (p = 0.029 for the allele G, p = 0.0124 for the genotype GG) was revealed. Significant differences in the frequencies of the studied polymorphisms in patients with the AZFc deletion and the control group of fertile men were not found. We showed significant differences in the frequencies for the combination of all high-risk polymorphisms in the control group, patients with the AZFc deletion and patients with TGCTs (p (TGCTs-AZF-control) = 0.0207). A fivefold increase in the frequency of the combination of all genotypes in the TGCT group (p = 0.0116; OR = 5.25 [1.44-19.15]) and 3.7-fold increase was identified in patients with the AZFc deletion (p = 0.045; OR = 3.69 [1.11-12.29]) were revealed. The genotyping of patients with infertility caused by the AZFc deletion can be used to

    Objective: Retrospectively analyze about the characteristics, therapeutic behavior and treatment results in patients with non-seminomatous testicular germ cell tumours (NSGCT) Stage III assisted in the University Hospital. Materials and Methods: The medical records of patients (pts) with histologically reviewed of NSGCT assisted in the Department of Clinical Oncology, Hospital das Clinicas (H C), among January 2000 and December 2009. We analyzed in detail the clinico pathological features of those belonging to pts with stage III tumors TNM classification. Results: 23 pts were included; median age 24 years (range: 17-40); median follow-up: 19 months (range: 2-104). Stadiums: I: 9/23; II: 7/23; III: 7/23. Among ptes E III.They corresponded to: high risk: 3/7; means: 3/7; Low: 1/7. Only in 1 patient (pte) of the E III It is not explicitly consisted risk rating in history but, based on data present is able to allocate retrospectively. The chemotherapy was the first line chosen, PE B plan pts 6/7 and 1/7 VIP (pte. athlete). All patients received 4 sets of PE B / VIP (including low risk). Imaging responses post chemotherapy (Q T): Complete: 1/7; Partial: 5/7; Stabilization: 1/7. In the 7 pts M T post Q T were normal. In 4 of the 7 pts who achieved partial response and normalized MTwe proceeded to surgery residual mass. The current status of patients is alive: 6/23; Dead: 4/23; monitoring loss (PDS): 13/23. The patients E III: Live 2/7, 4/7 dead, PDS 1/7.4 E III patients were dead with diagnosis (high risk 3/4, 1/4 medium). He did not make the survival analysis given the low and high percentage of patients PDS. Conclusions: In the last 10 years only 7 patients with NSGCT E III attended the H C (0.7 / year). Overall front line management adjusted to the recommendations international but the management of patients with residual mass and not normal M T necessarily. While the number of patients is too low to definitive conclusions, the C R rate to Q T 1st line impresses be

    Full Text Available The incidence of bilateral testicular cancer is 5% in the total cohort of patients. Synchronous and metachronous testicular cancers are detected in 1-2 and 3% of cases, respectively. The standard treatment for testicular cancer is orchifuniculectomy and that for synchronous or metachronous cancer is organ-saving treatment, testectomy.The paper describes a clinical case of multiple primary metachronous testicular cancer. A 24-year-old patient underwent surgery (orchifuniculectomy and received 4 courses of BEP polychemotherapy for embryonal carcinoma of the left testicle at the P.A. Herzen Moscow Oncology Research Institute. After 55 months, a dynamic control examination diagnosed a 9-mm tumor in his single right testis that was thereafter resected. Its histological examination revealed embryonal carcinoma with solitary structures in the immature teratoma. Following 22 months, a control examination showed a recurrence of the disease, for which orchifuniculectomy of the single right testis, followed by hormone replacement therapy, was performed. The follow-up period was 80 months; no recurrence is now observed.

    Elevated levels of EMMPRIN/CD147 in cancer tissues have been correlated with tumor progression but the regulation of its expression is not yet understood. Here, the regulation of EMMPRIN expression was investigated in testicular germ cell tumor (TGCTs) cell lines. EMMPRIN expression in seminoma JKT-1 and embryonal carcinoma NT2/D1 cell lines was determined by Western blot, immunofluorescence and qRT-PCR. Membrane vesicles (MVs) secreted from these cells, treated or not with EMMPRIN siRNA, were isolated by differential centrifugations of their conditioned medium. MMP-2 was analyzed by zymography and qRT-PCR. The more aggressive embryonic carcinoma NT2/D1 cells expressed more EMMPRIN mRNA than the seminoma JKT-1 cells, but surprisingly contained less EMMPRIN protein, as determined by immunoblotting and immunostaining. The protein/mRNA discrepancy was not due to accelerated protein degradation in NT2/D1 cells, but by the secretion of EMMPRIN within MVs, as the vesicles released from NT2/D1 contained considerably more EMMPRIN than those released from JKT-1. EMMPRIN-containing MVs obtained from NT2/D1, but not from EMMPRIN-siRNA treated NT2/D1, increased MMP-2 production in fibroblasts to a greater extent than those from JKT-1 cells. The data presented show that the more aggressive embryonic carcinoma cells synthesize more EMMPRIN than seminoma cells, but which they preferentially target to secreted MVs, unlike seminoma cells which retain EMMPRIN within the cell membrane. This cellular event points to a mechanism by which EMMPRIN expressed by malignant testicular cells can exert its MMP inducing effect on distant cells within the tumor microenvironment to promote tumor invasion.

    Cryptorchism is one of the few well-described risk factors for testicular cancer. It has been suggested that both conditions are related to increased in utero estrogen exposure. The evidence supporting the "estrogen hypothesis" has been inconsistent, however. An alternative hypothesis suggests that higher in utero androgen exposure may protect against the development of cryptorchism and testicular cancer. In order to examine both hypotheses, we studied maternal hormone levels in two populations at diverse risks of testicular cancer; Black Americans (low-risk) and White Americans (high-risk). The study population of 200 mothers of cryptorchid sons and 200 mothers of noncryptorchid sons was nested within the Collaborative Perinatal Project, a cohort study of pregnant women and their children. Third trimester serum levels of estradiol (total, free, bioavailable), estriol, testosterone (total, free, bioavailable), sex hormone-binding globulin, alpha-fetoprotein, and the ratios of estradiols to testosterones were compared between the case and control mothers. The results found no significant differences in the levels of testosterone (total, free, bioavailable), alpha-fetoprotein, sex hormone-binding globulin, or in the ratios of estrogens to androgens. Total estradiol, however, was significantly lower in the cases versus the controls (P = 0.03) among all mothers and, separately, among White mothers (P = 0.05). Similarly, estriol was significantly lower among all cases (P = 0.05) and among White cases (P = 0.05). These results do not support either the estrogen or the androgen hypothesis. Rather, lower estrogens in case mothers may indicate that a placental defect increases the risk of cryptorchism and, possibly, testicular cancer.

    Full Text Available Introduction: von Hippel-Lindau disease (vHL disease is a hereditary disease in which tumors and cysts develop in many organs, in association with central nervous system hemangioblastomas, pheochromocytomas, and pancreatic tumors. We herein report a case of vHL disease (type 2A associated with bilateral pheochromocytomas, pancreatic neuroendocrine tumors (PNET, and cerebellar hemangioblastomas treated via pancreatectomy after adrenalectomy. Case presentation: A 51-year-old woman presented with a cerebellar tumor, bilateral hypernephroma, and pancreatic tumor detected during a medical checkup. 18F-fluorodeoxyglucose positron emission tomography–computed tomography revealed a bilateral adrenal gland tumor and a tumor in the head of the pancreas, while an abdominal computed tomography examination revealed a 30-mm tumor with strong enhancement in the head of the pancreas. Cranial magnetic resonance imaging showed a hemangioblastoma in the cerebellum. Therefore, a diagnosis of vHL disease (type 2A was made. Her family medical history included renal cell carcinoma in her father and bilateral adrenal pheochromocytoma and spinal hemangioblastoma in her brother. A detailed examination of endocrine function showed that the adrenal mass was capable of producing catecholamine. Treatment of the pheochromocytoma was prioritized, and therefore, laparoscopic left adrenalectomy and subtotal resection of the right adrenal gland were performed. Once the postoperative steroid levels were replenished, subtotal stomach-preserving pancreatoduodenectomy was performed for the PNET. After a good postoperative course, the patient was discharged in remission on the 11th day following surgery. Histopathological examination findings indicated NET G2 (MIB-1 index 10–15% pT3N0M0 Stage II A and microcystic serous cystadenoma throughout the resected specimen. The patient is scheduled to undergo treatment for the cerebellar hemangioblastoma. Conclusion: A two-staged resection

    Familial occurrence belongs to factors followed in etiology and pathogenesis of testicular germ-cell tumors. Association with abnormal testicular development, or with other risk factors is relatively frequent. In our material 650 patients had been treated for testicular cancer in the period of 1981-1995. Familial occurrence was observed 7-times (1.08), most frequently in combination with cryptorchidism. Individual families were analyzed in details, including HLA typing. On basis of the observations the supplementation of initial examination of each patient with suspicious testicular cancer with detailed familiar history aimed also at the occurrence of urogenital developmental anomalies and tumors has been recommended. The knowledge about familial tumor occurrence in the first-degree relatives in combination with thorough testicular self-examination is being considered of great importance in the secondary prevention.

    Breast cancer has the highest rate of incidence among all types of cancer in women. Only ~0.43% of breast malignancies occur as a result of metastatic lesions from extramammary tumors. The present study reports an extremely rare case of transverse colon cancer metastasizing to the bilateral ovaries and the left breast. The patient was a 47-year old female, who had a lump in the left breast without axillary lymphadenopathy. Specimens obtained by core needle biopsy were submitted for hematoxylin and eosin examination, and results revealed that the lump was a poorly differentiated adenocarcinoma. Since the patient had elevated levels of the carcinoembryonic antigen and a medical history of a Krukenberg tumor metastasized from colon cancer, immunohistochemical examinations were applied. Results identified that caudal-related homeobox protein 2 and cytokeratin 20 were positively stained, whilst cytokeratin 7 was negatively stained. Therefore, this patient was diagnosed as having colon cancer that had metastasized to the bilateral ovaries and the left breast. As the life expectancy of patients with cancer is increasing, types of metastases that used to be seen as rare are increasingly becoming more common. For clinicians, diagnosis should be cautious, and differential diagnosis should always be kept in mind.

    Prolonged bisphosphonate use has been associated with increased risk of atypical femoral fractures. Very few cases of atypical femoral fractures have been reported with denosumab. We report a case of bilateral tibial stress reactions in a 60-year-old man with no history of osteoporosis who was on prolonged high-dose denosumab for the treatment of giant cell tumor of bone. He presented with a 3-month history of pain in his bilateral shins worsening with activity and improving with rest. Although initial radiographs were unremarkable, he was found to have changes consistent with a stress reaction on magnetic resonance imaging of the distal tibia. To our knowledge, bilateral tibial stress reactions have not been previously reported with anti-resorptive therapies (neither bisphosphonates nor denosumab). Our case is intriguing in terms of the development of stress reactions as a precursor to stress fractures which may also relate to atypical fractures. Our case suggests a possible association between denosumab use and stress reactions. Of note the indication for denosumab in our case was for the treatment of giant cell tumor of bone where the Food and Drug Administration (FDA) approved dose is substantially higher than the FDA approved dose for osteoporosis treatment. Although rare, clinicians should consider the possibility of stress fractures in patients on anti-resorptive medications such as denosumab, especially when a patient presents with new onset thigh pain, hip pain or pain over an area affecting the long bones. Evaluation by imaging of affected areas should be pursued to enable early detection and intervention, as well as prevention of morbidity and associated ongoing risk to the patient.

    Patients with a primary pure seminoma in the testis who have elevated serum alpha-fetoprotein are rare and should be treated as patients with nonseminomatous germ cell tumors. However, nonpalpable testicular tumors in this condition have never been reported. We describe a case of nonpalpable pure testicular seminoma with elevated serum alpha-fetoprotein presenting retroperitoneal metastasis. A 29-year-old Asian man was referred to our hospital with right flank pain. Computed tomography showed a mass located between his aorta and inferior vena cava, but a testicular tumor was not detected. His serum levels of lactate dehydrogenase, alpha-fetoprotein, and DUPAN-2 were high. Although no tumor or nodule was palpable in his testis, ultrasonography revealed multiple low echoic lesions in his right testicular parenchyma. He was diagnosed with right testicular cancer with retroperitoneal lymph node metastasis and underwent right high orchiectomy. A pathological examination revealed pure seminoma and no nonseminomatous components were found in the specimen. Three courses of induction systemic chemotherapy (cisplatin, etoposide, and bleomycin) normalized his serum alpha-fetoprotein and DUPAN-2 levels. Three additional courses of chemotherapy (etoposide and bleomycin) were performed, and treatment was completed with laparoscopic retroperitoneal lymph node dissection. Pathology of the dissected specimen showed fibrous and necrotic tissue with no viable cells. He is alive without recurrence 54 months after orchiectomy. We report a case of pure testicular seminoma with elevated serum alpha-fetoprotein and DUPAN-2 presenting retroperitoneal metastasis. We recommend an ultrasound examination of bilateral testes when large retroperitoneal tumors are detected in young men, even if a mass is not palpable in the scrotum.

  8. Mutational Profiling Can Establish Clonal or Independent Origin in Synchronous Bilateral Breast and Other Tumors.

    Directory of Open Access Journals (Sweden)

    Lei Bao

    Full Text Available Synchronous tumors can be independent primary tumors or a primary-metastatic (clonal pair, which may have clinical implications. Mutational profiling of tumor DNA is increasingly common in the clinic. We investigated whether mutational profiling can distinguish independent from clonal tumors in breast and other cancers, using a carefully defined test based on the Clonal Likelihood Score (CLS = 100 x # shared high confidence (HC mutations/ # total HC mutations.Statistical properties of a formal test using the CLS were investigated. A high CLS is evidence in favor of clonality; the test is implemented as a one-sided binomial test of proportions. Test parameters were empirically determined using 16,422 independent breast tumor pairs and 15 primary-metastatic tumor pairs from 10 cancer types using The Cancer Genome Atlas.We validated performance of the test with its established parameters, using five published data sets comprising 15,758 known independent tumor pairs (maximum CLS = 4.1%, minimum p-value = 0.48 and 283 known tumor clonal pairs (minimum CLS 13%, maximum p-value 0.99, supporting independence. A plausible molecular mechanism for the shift from hormone receptor positive to triple negative was identified in the clonal pair.We have developed the statistical properties of a carefully defined Clonal Likelihood Score test from mutational profiling of tumor DNA. Under identified conditions, the test appears to reliably distinguish between synchronous tumors of clonal and of independent origin in several cancer types. This approach may have scientific and clinical utility.

    Prepubertal testicular tumors are rare, and teratoma is the second most frequent histologic type. Its typical features are those of a hard and painless scrotal mass at clinical examination, and nonhomogeneous, echoic, often with calcifications at ultrasonography. Rare but reported is the atypical presentation as a transilluminating scrotal mass, due to the presence of some internal cystic areas, detectable at ultrasonography. We report the case of an infant with a transilluminating scrotal mass, mimicking at ultrasonography and surgery a simple, fully liquid cyst, which the pathologic examination revealed to be mature cystic testicular teratoma.

    Calcification of the basal ganglia subsequent to radiation therapy for childhood brain tumors has rarely been reported. Three cases of this calcification subsequent to radiation are presented here. Case 1 is a 7 year-old boy who underwent irradiation of 5000 rads locally for craniopharyngioma at the age of 4 years. Case 2 is a 4 year-old boy who was treated with irradiation of 4500 rads locally for cerebellar medulloblastoma at the age of 1 year. Case 3 is a 15 year-old girl who was treated with irradiation of 5000 rads to the brain and 3000 rads locally for suprasellar germinoma at the age of 11 years. In all these cases, the interval between radiation and evidence of calcification as detected only by CT scan, was more than 3 years and 2 cases are experiencing mild mental retardation. These findings suggest the possibility of long-term complications due to radiation therapy.

    Testes of adult, male rats were exposed to a total dose of 1500 R of X-irradiation. Testicular weight decreased from day 8 after X-ray treatment. This decrease was, however, precded by an increment of the testis weight on day 4 following treatment. X-ray treatment of testes was associated with significant increase in serum FSH. Testicular irradiation had, however, no effect on ventral prostate and seminal vesicles weights. Serum testosterone increased only on day 1, 2 and 4 after irradiation, while serum LH levels tended to increase from day 8 post-irradiation. These changes were not significant, however, when compared with non-irradiated controls. At 7, 13 and 20 days following 1500 R of bilateral, testicular X-irradiation, the hypothalamic-pituitary unit was still capable of responding to exogenous gonadotrophin releasing factor. Serum FSH may in male rats be regulated at least partly by circulating steroids of testicular origin and partly by an unknown factor of non-interstitial cell nature. (author)

    Metastatic ovarian tumors from colon cancer would be resistant to chemotherapy, and compromising quality of life(QOL) of these patients was caused by acute enlargement of the tumors. A 37-year-old woman with abdominal distension was diagnosed with transverse colon cancer, bilateral ovarian metastases, liver metastases, and peritoneal dissemination at prior hospital. Two courses of chemotherapy(FOLFOX)were administered, but metastaticovarian tumors enlarged. Chemotherapy was discontinued and she was referred to our institution. To achieve symptom relief, improving QOL, and to resume chemotherapy, we planned bilateral oophorectomy and primary tumor resection if other stenotic lesion was not present. As a result, we safely performed open bilateral oophorectomy and right hemi colectomy, and the patient discharged on postoperative day 11 without complications. Chemotherapy was resumed and continued for 7 months up to this time. Even though, curative resection could not be achieved, oophorectomy should be performed in patients with enlarged metastatic ovarian tumor from colon cancer, in spite of administration of chemotherapy.

    Testicular torsion is a medical emergency that usually requires surgical exploration. However, testicular malignancy has been anecdotally reported with the association of torsion in surgical specimens, and the published data remain scant on the association of torsion with testicular tumors. By retrospective medical record review, we identified 32 patients who had been diagnosed with testicular torsion, 20 of whom had undergone orchiectomy. Of these 20 patients, 2 were diagnosed with a malignancy. Our study, the largest case series to date, has shown an association between testicular torsion and testicular cancer of 6.4%. Testicular torsion is a medical emergency that usually requires surgical exploration. However, testicular malignancy has been anecdotally reported in association with torsion in surgical specimens. However, the published data remain scant on the association between torsion and the presence of testicular tumors. The present retrospective study explored the association between torsion and testicular cancer in patients with testicular torsion undergoing orchiectomy during scrotal exploration. A medical record review was performed of patients who had had a diagnosis of testicular torsion from January 2003 to February 2015. The clinicopathologic characteristics of the patients were recorded. A total of 32 patients were identified. Their mean age was 21.1 years (range, 7-39 years). All the patients had unilateral testicular torsion, which affected the left side in 17 and the right side in 15. Manual detorsion was successful in 6 patients, and 26 patients underwent emergency surgery with testicular detorsion (6 fixation surgery and 20 orchiectomy). The type of incision was scrotal in 6, inguinal in 10, and unspecified in 4. Pathologic examination of the orchiectomy specimens showed malignancy in 2 cases (seminoma and malign mixed germ cell tumor). To the best of our knowledge, the present single-center case series is the largest case series to date of

    This study is a review of 39 patients with testicular seminoma, Stage I, treated at the Department of Radiation Oncology, James Graham Brown Cancer Center from 1959 to 1978. The age of the patients ranged from 16 to 70 years with a median of 37. Thirty-two (82%) patients presented with swelling or mass in the testis, four patients with pain, and three patients had seminoma diagnosed incidentally. Twenty (51%) patients had the tumor on the right side and 19 (49%) patients had the tumor on the left side. All patients received irradiation to the ipsilateral inguinal, iliac, and bilateral para-aortic nodes with ''hockey stick'' type fields. The majority of the patients received a midplane dose of 3,200 to 3,600 rad in 3-4 weeks time. None of the patients received prophylactic irradiation to the mediastinum and supraclavicular region. The 5-year actuarial survival rate is 96%. There is no additional benefit in giving prophylactic irradiation to the mediastinum and supraclavicular regions in Stage I testicular seminoma. A brief review of the literature regarding the role of prophylactic irradiation in this group of patients is done

    Full Text Available The tumor de novo in the residual kidney after surgery for nonfamilial bilateral renal cell carcinoma (RCC is problematic. We reviewed 5 patients who experienced such a situation. Three patients had had metachronous bilateral RCC, treated with radical nephrectomy in one kidney and nephron-sparing surgery (NSS in the other. Two patients had had synchronous disease; one patient had received radical nephrectomy and NSS, and the other bilateral NSS. The 5 patients had another solid mass/de novo tumor in the residual kidney 16–88 (mean 46.8 months after surgery. For the tumor de novo in earlier years (1992–1999, one patient underwent surgery and hemodialysis, and the other selected a conservative observation. In recent years (2000–2007, one patient was conservatively observed; the remaining 2 received computerized-tomography-guided radiofrequency ablation, and the local tumors were well controlled postoperatively for 20 and 12 months with their renal function unimpaired. Ablative techniques can potentially strike a balance between oncological and nephrological outcomes in patients with sporadic multiple RCC, successful management of which was difficult previously.

    Full Text Available Introduction: There is evidence that inherited genetic variation affects both testicular germ cell tumor (TGCT treatment outcome and risks of late-complications arising from cisplatin-based chemotherapy. Using a candidate gene approach, we examined associations of three genes involved in the cisplatin metabolism pathway, GSTP1, COMT, and TPMT, with TGCT outcome and cisplatin-induced neurotoxicity. Material and Methods: Our study population includes a subset of patients (n=137 from a genome-wide association study at the University of Pennsylvania that evaluates inherited genetic susceptibility to TGCT. All patients in our study had at least one course of cisplatin-based chemotherapy with at least one year of follow up. A total of 90 markers in GSTP1, COMT and TPMT and their adjacent genomic regions (± 20 kb were analyzed for associations with refractory TGCT after first course of chemotherapy, progression-free survival (PFS, overall survival (OS, peripheral neuropathy, and ototoxicity. Results: After adjustment for multiple comparisons, one SNP, rs2073743, in the flanking region (± 20 kb of COMT was associated with refractory TGCT after initial chemotherapy. This SNP lies within the intron region of the Armadillo Repeat gene deleted in Velco-Cardio-Facial syndrome (ARVCF. The G allele of rs2073743 predisposed patients to refractory disease with a relative risk of 2.6 (95% CI 1.1, 6.3; P=0.03. Assuming recessive inheritance, patients with the GG genotype had 22.7 times higher risk (95% CI 3.3, 155.8; P=0.04 of developing refractory disease when compared to those with the GC or CC genotypes. We found no association of our candidate genes with peripheral neuropathy, ototoxicity, PFS and OS. Discussion: This is the first study to suggest that germline genetic variants of ARVCF may affect TGCT outcome. The result of this study is hypothesis generating and should be validated in future studies.

    Genome-wide association (GWA) studies have reported 19 distinct susceptibility loci for testicular germ cell tumor (TGCT). A GWA study for TGCT was performed by genotyping 610 240 single-nucleotide polymorphisms (SNPs) in 1326 cases and 6687 controls from Sweden and Norway. No novel genome-wide significant associations were observed in this discovery stage. We put forward 27 SNPs from 15 novel regions and 12 SNPs previously reported, for replication in 710 case-parent triads and 289 cases and 290 controls. Predefined biological pathways and processes, in addition to a custom-built sex-determination gene set, were subject to enrichment analyses using Meta-Analysis Gene Set Enrichment of Variant Associations (M) and Improved Gene Set Enrichment Analysis for Genome-wide Association Study (I). In the combined meta-analysis, we observed genome-wide significant association for rs7501939 on chromosome 17q12 (OR = 0.78, 95% CI = 0.72-0.84, P = 1.1 × 10(-9)) and rs2195987 on chromosome 19p12 (OR = 0.76, 95% CI: 0.69-0.84, P = 3.2 × 10(-8)). The marker rs7501939 on chromosome 17q12 is located in an intron of the HNF1B gene, encoding a member of the homeodomain-containing superfamily of transcription factors.

    Carney complex (CNC) is an autosomal dominant multiple neoplasia, caused mostly by inactivating mutations of the regulatory subunit 1A of the protein kinase A (PRKAR1A). Primary pigmented nodular adrenocortical disease (PPNAD) is the most frequent endocrine manifestation of CNC with a great inter-individual variability. Germline, protein-truncating mutations of phosphodiesterase type 11A (PDE11A) have been described to predispose to a variety of endocrine tumors, including adrenal and testicular tumors. Our objective was to investigate the role of PDE11A as a possible gene modifier of the phenotype in a series of 150 patients with CNC. A higher frequency of PDE11A variants in patients with CNC compared with healthy controls was found (25.3 vs. 6.8%, P CNC patients, those with PPNAD were significantly more frequently carriers of PDE11A variants compared with patients without PPNAD (30.8 vs. 13%, P = 0.025). Furthermore, men with PPNAD were significantly more frequently carriers of PDE11A sequence variants (40.7%) than women with PPNAD (27.3%) (P CNC patients, a high frequency of PDE11A variants, suggesting that PDE11A is a genetic modifying factor for the development of testicular and adrenal tumors in patients with germline PRKAR1A mutation.

The syndrome is characterized by neoplasia of the parathyroid and pituitary glands, and malignant tumors of the endocrine pancreas. Other manifestations include benign lipomas, angiofibromas, and carcinoid tumors commonly originating in the colon, thymus, and lung. This is the first report of MEN1 syndrome manifesting as bilateral granulosa cell ovarian tumors, and which is associated with a rare intronic mutation of the MEN1 gene. Case report: A 41-year-old woman presented with abdominal pain, increasing abdominal girth, and dysmenorrhea. Ultrasound demonstrated enlarged ovaries and uterine fibroids. After an exploratory laparotomy, she subsequently underwent bilateral salpingo–oophorectomy with hysterectomy where the pathology revealed bilateral cystic granulosa cell tumors of the ovaries. Additional workup including computed tomography imaging discovered a thymic mass, which the pathology showed was malignant, along with a pancreatic mass suspicious for a neuroendocrine tumor. Hyperparathyroidism was also discovered and was found to be secondary to a parathyroid adenoma. Genetic testing revealed an exceedingly rare mutation in the MEN1 gene (c.654 + 1 G>A. Discussion: Mutations of the menin gene leading to MEN1 syndrome are classically nonsense or missense mutations producing a dysfunctional protein product. Recently, researchers described a novel mutation of MEN1 (c.654 + 1 G>A in a male proband meeting the criteria

    We herein report the case of a 75-year-old female patient who underwent 4 surgeries for bilateral breast cancer and its recurrence. When she presented at a clinic with an irritable colon, a fist-sized tumor was palpated in the right upper abdomen at her first medical examination. Abdominal CT scan at the clinic revealed a tumor with a maximum diameter of 10 cm on the right side of the transverse colon and multiple swollen mesenteric lymph nodes. Therefore, the patient was referred to our hospital for surgery. Colonoscopy revealed stenosis of the same lesion with an edematous mucosa and sclerosis. Using immunohistochemistry, a biopsy specimen from the lesion tested positive for CK AE1+AE3, and negative for CD20(-)and CD3 (-). As a result, the tumor was diagnosed as a poorly differentiated adenocarcinoma. We performed right hemicolectomy to avoid her intestinal obstruction. Tumor cells were mainly present at the subserosa, according to HEstaining. Using immunostaining, the cells were tested for the following markers: CDX2(-), GCDFP15(weakly positive), CK7(strongly positive), CD20(partially positive), E R(+), PgR(-), and HER2(1+), characterizing the tumor as metastasis of breast cancer. Although gastro-intestinal metastasis from breast cancer is rare, and colon metastasis is even rarer, it might be necessary to rule out the possibility of a metastatic colon tumor from breast cancer when treating patients with a colon tumor who have undergone surgery for breast cancer.

    Full Text Available Metastatic testicular cancers are rare. Primary tumor sources are prostate, lung, and gastrointestinal tract for metastatic testicular cancers. Metastasis of urothelial carcinoma (UC to the testis is extremely rare. Two-thirds of upper tract urothelial carcinoma (UTUC is of invasive stage at diagnosis and metastatic sites are the pelvic lymph nodes, liver, lung, and bone. We report a rare case of metastatic UTUC to the testis which has not been reported before, except one case in the literature. Testicular metastasis of UC should be considered in patients with hematuria and testicular swelling.

    Full Text Available Background: Clusterin, a heterodimeric glycoprotein of approximately 80 kDa, exists extensively in human body fluids. The abnormal expression of clusterin is closely related to the occurrence, progression, and prognosis of tumors. Up to now, few studies have focused on clusterin in human testicular cancer. This study describes an extensive exploration of the presence and expression of clusterin in testicular seminoma. Methods: Tumor tissues and normal testis tissues were collected from 13 patients with testicular seminoma and 16 patients undergoing surgical castration for prostate cancer. Real-time polymerase chain reaction (PCR was performed to detect the expression difference of clusterin mRNA between testicular seminoma and normal testis. Western blot and immunohistochemical analysis were performed to detect the presence and expression difference of clusterin protein between two groups. Results: Real-time PCR showed the expression of clusterin mRNA in testicular seminoma to be significantly lower than in normal testis (only 13% relative quantification. Western blot analysis indicated marked reductions in the expression of clusterin protein in testicular seminoma. Similar results were observed upon immunohistochemical analysis. Conclusion: In testicular seminoma and normal testis, clusterin exists in its heterodimeric secretory isoform. Clusterin expression is significantly lower in testicular seminoma than in normal testis. This is the first comprehensive study of the presence and expression of clusterin in human testicular cancer.

  15. Secondary malignant neoplasms in testicular cancer survivors.

    Curreri, Stephanie A; Fung, Chunkit; Beard, Clair J

    2015-09-01

    Testicular cancer is the most common cancer among men aged 15 to 40 years, and the incidence of testicular cancer is steadily increasing. Despite successful treatment outcomes and the rate of survival at 5 to 10 years being 95%, survivors can experience late effects of both their cancer and the treatment they received, including secondary malignant neoplasms (SMNs). We discuss the development of non-germ cell SMNs that develop after diagnosis and treatment of testicular cancer and their effect on mortality. Patients diagnosed with testicular cancer frequently choose postoperative surveillance if they are diagnosed with clinical stage I disease. These patients may experience an increased risk for developing SMNs following radiation exposure from diagnostic imaging. Similarly, radiotherapy for testicular cancer is associated with increased risks of developing both solid tumors and leukemia. Studies have reported that patients exposed to higher doses of radiation have an increased risk of developing SMNs when compared with patients who received lower doses of radiation. Patients treated with chemotherapy also experience an increased risk of developing SMNs following testicular cancer, though the risk following chemotherapy and radiation therapy combined is not well described. A large population-based study concluded that the rate ratios for both cancer-specific and all-cause mortality for SMNs among testicular cancer survivors were not significantly different from those of matched first cancers. Although it is known that patients who receive adjuvant chemotherapy or radiotherapy or who undergo routine diagnostic or follow-up imaging for a primary testicular cancer are at an increased risk for developing SMNs, the extent of this risk is largely unknown. It is critically important that research be conducted to determine this risk and its contributing factors as accurately as possible. Copyright © 2015 Elsevier Inc. All rights reserved.

    Radioisotopic scrotal angiography was applied for study of testicular blood flow of patients with varicocele. Following iv. bolus injection of 10 ∼ 20 mCi of Tc human serum albumine, Tc RBC or Tc pertechnetate, time activity curve of radioactivity at corresponding bilateral areas of scrotum was simultaneously generated and compared. Eighty-four patients with overt varicocele (grade 2 and 3) at left side only, were selected for the present study and eight healthy young volunteers were studied as a control group. Three patterns of time activity curves were recognized. They are as follows. Type 1, where radioactivity was accumulated quickly in left side and then decreased gradually. Bilateral time activity curves were asymmetrical. Type 2, where time activity curves rose gradually and to a higher level at the left side than at the right side. Type 3, where bilateral time activity curves increased gradually, and symmetrically. All of the control group showed the same pattern as Type 3. Of the 84 patients examined, 34 patients showed Type 1, including 7 with grade 2 and 27 with grade 3. Twenty-four patients showed Type 2. consisting of 12 with grade 2 and 12 with grade 3. Twenty-six patients showed Type 3, consisting of 14 with grade 2 and 12 with grade 3. We presumed the following about testicular blood flow in varicocele: Type 1 pattern shows retrograde blood flow from the renal vein to the internal spermatic vein, Type 2 pattern shows poor venous return through the internal spermatic vein and Type 3 pattern shows good venous return though the presence of dilatated pampiniform plexus.

    Rapid and effective treatment of cancer-induced bone pain remains a clinical challenge and patients with bone metastasis are more likely to experience severe pain. The voltage-gated sodium channel Nav1.8 plays a critical role in many aspects of nociceptor function. Therefore, we characterized a rat model of cancer pain and investigated the potential role of Nav1.8. Adult female Wistar rats were used for the study. Cancer pain was induced by inoculation of Walker 256 breast carcinosarcoma cells into the tibia. After surgery, mechanical and thermal hyperalgesia and ambulation scores were evaluated to identify pain-related behavior. We used real-time RT-PCR to determine Nav1.8 mRNA expression in bilateral L4/L5 dorsal root ganglia (DRG) at 16-19 days after surgery. Western blotting and immunofluorescence were used to compare the expression and distribution of Nav1.8 in L4/L5 DRG between tumor-bearing and sham rats. Antisense oligodeoxynucleotides (ODNs) against Nav1.8 were administered intrathecally at 14-16 days after surgery to knock down Nav1.8 protein expression and changes in pain-related behavior were observed. Tumor-bearing rats exhibited mechanical hyperalgesia and ambulatory-evoked pain from day 7 after inoculation of Walker 256 cells. In the advanced stage of cancer pain (days 16-19 after surgery), normalized Nav1.8 mRNA levels assessed by real-time RT-PCR were significantly lower in ipsilateral L4/L5 DRG of tumor-bearing rats compared with the sham group. Western-blot showed that the total expression of Nav1.8 protein significantly decreased bilaterally in DRG of tumor-bearing rats. Furthermore, as revealed by immunofluorescence, only the expression of Nav1.8 protein in small neurons down regulated significantly in bilateral DRG of cancer pain rats. After administration of antisense ODNs against Nav1.8, Nav1.8 protein expression decreased significantly and tumor-bearing rats showed alleviated mechanical hyperalgesia and ambulatory-evoked pain.

    Intracranial malignant solitary fibrous tumor (MSFT) is extremely rare. The authors report a case of MSFT of the right occipital lobe with a rapid recurrence and bilateral lung, multiple bone metastasis. The patient was a 25-year-old male presenting with headache, nausea and visual disturbances without obvious cause. Three times right-side occipital craniotomies were performed and two times postoperative conformal radiotherapy were administered within one year. 4 months after the third time of right-side occipital craniotomy, the patient felt right chest pain and neck pain. Positron emission tomography/computed tomography (PET/CT) showed tumor recurrence of the right occipital lobe and bilateral lung metastasis, multiple bone metastasis including: vertebrae, libs, the left iliac wing, sacrum, the right ischium and upper parts of both femurs. Ultrasound guided puncture biopsy of left-side back of the neck and CT guided puncture biopsy of the third lumbar vertebra were performed. General sample showed grayish white or grayish red with irregular shape. Histopathologically, the tumor was composed of areas of alternating hypercellularity and hypocellularity with spindle-shaped cells, which arranged as fascicular, storiform pattern or patternless pattern, with intervening irregular eosinophilic collagen bundles. Some areas showed hemangiopericytoma-like perivascular pattern and perivascular hyalinization.

    The absence of a testis occurs for various reasons in children, but testicular prosthesis implantation in children is uncommon. The optimal time for prosthesis placement is still unclear, and its complication rate has been poorly studied in children. The aim of this study was to determine the risk factors of complications in cases of testicular prosthesis implantation in children. A monocentric, retrospective review was performed of children implanted with a testicular prosthesis between 2008 and 2014. All implantations were performed through an inguinal incision with a standardized procedure. Children were divided into two groups depending on the interval after orchiectomy: (A) early implantation (delay between surgeries prosthesis implantation at the mean age of 14.7 years (range 9-18) (A, 14.3; B, 14.6) with a mean delay of 36.1 months (A, 1.3; B, 80.3). Indications were mainly spermatic cord torsion (27%), bilateral anorchia (27%), and testicular atrophy after cryptorchidism surgery (19.2%). Complications (10.5%) included two cases of extrusion, one infection and one migration. Patient 1 had a history of acute lymphoblastic leukemia with testicle relapse 2 years after induction therapy. High-dose chemotherapy, total body irradiation and bilateral orchiectomies were performed, and bilateral prostheses were implanted 12 years after the end of chemotherapy. Complications happened 85 days after surgery. Patient 2 was followed-up for a proximal hypospadias. The tunica vaginalis flap, which was used during a redo urethroplasty, lead to testicular atrophy. Thirteen years after the last penile surgery, a testicular prosthesis was placed through an inguinal incision, and extrusion occurred 203 days after surgery. Bacterial cultures of the prostheses were sterile and histological review showed no sign of granuloma or graft rejection. The complication rate was significantly higher if the delay between the two surgeries exceeded 1 year (P = 0.01). Indications of

    We present additional clinical evidence for the suspected association of Down's syndrome and testicular germ cell tumors. Four cases of Down's syndrome and testicular cancer are reported. The literature was reviewed for previous cases and analysis regarding common features. The 4 patients were 29 to 35 years old and had clinical stage I seminoma of the testis. Two patients received prophylactic abdominal radiotherapy, 1 is being followed and 1 received adjuvant carboplatin treatment. There was no relapse at followup of 1 to 8 years. One patient also had contralateral cryptorchidism. A total of 16 cases with the association of Down's syndrome and testicular germ cell cancer was documented previously. Evidence for the suspected association of Down's syndrome and testicular cancer is now accumulating. Etiologically it is suspected that, along with genetically determined malformations in many other organs in trisomy 21, the gonads also undergo maldevelopment, thus creating the conditions for step 1 of germ cell tumor oncogenesis in utero. Physicians caring for patients with Down's syndrome should be aware of the possible association with testicular neoplasms.

    The present study aimed at resolving whether dynamic MRT can improve diagnostic relevance in diseases of the testes compared with conventional spin echo images. The testes of 20 healthy volunteers and of 16 patients of the Department of Urology of the University of Bonn were examined by means of MR tomography. Within 12 hours after MR tomography the patients were surgically explored, biopsied and if necessary orchiectomised. Results obtained with the volunteers were uniform and well reproducible, independent of external influences. On comparing the maximal enhancement curves of the examined various testicular tumors with the standard values established by examining the healthy volunteers, the curves obtained with the malignant testicular tumors were always clearly above the chosen confidence range of 3 standard deviations so that malignancy diagnosis was easy. However, the degree of maximal enhancement did not enable us to arrive at a conclusion in respect of the tumor type or the degree of malignancy. The greatest enhancement occurred with the tumor of Sertoli's cell which could thus be clearly differentiated against the other malignant testicular tumors. Due to masking of the gadolinium effect by haemosiderin deposits, haemorrhagica in the tumor tissue should be excluded by means of T 2 -weighted spin echo sequences before following up a suspicion of malignant testicular tomor. Benign intratesticular changes could be safely separated from malignant findings by means of the maximal enhancement curve lying in the normal range or below the curve of the volunteers. As with other organs, dynamic MR tomography yields definitely more and better information than conventional MR tomography also in the diagnosis of testicular tumours. However, these ''pros'' do not offset the ''cons'' of high costs of such examinations. (orig.) [de

    Myeloid sarcomas are extramedullary solid tumors composed of immature granulocytic precursor cells. In association with acute myeloid leukemia and other myeloproliferative disorders, they may arise concurrently with compromised bone marrow related to acute myeloid leukemia, as a relapsed presentation, or occur as the first manifestation. The testicles are considered to be an uncommon site for myeloid sarcomas. No therapeutic strategy has been defined as best but may include chemotherapy, radiotherapy and/or hematopoietic stem cell transplantation. This study reports the evolution of a patient with testicular myeloid sarcoma as the first manifestation of acute myeloid leukemia. The patient initially refused medical treatment and died five months after the clinical condition started.

    Full Text Available Testicular neoplasm accounts for about 1% of all cancers in men. Over the last 40 years, the incidence of testicular cancer has increased in northern European male populations for unknown reasons. When diagnosed at early stage, testicular cancer is usually curable with a high survival rate. In the past three decades, successful multidisciplinary approaches for the management of testicular cancer have significantly increased patient survival rates. Utilization of tumor markers and accurate prognostic classification has also contributed to successful therapy. In this article, we highlight the most commonly used tumor markers and several potential "novel" markers for testicular cancer as part of the ongoing effort in biomarker research and discovery. In addition, this article also identifies several key prognostic features that have been demonstrated to play a role in predicting relapse. These features include tumor size, rete testis invasion, lymphovascular invasion, and tumor histology. Together with tumor markers, these prognostic factors should be taken into account for risk-adapted management of testicular cancer.

    Little is known about preorchiectomy Leydig cell function in patients with testicular germ cell cancer (TGCC). The aim was to estimate the prevalence of preorchiectomy Leydig cell dysfunction and evaluate factors associated with this condition in a cohort of patients with TGCC. We evaluated luteinizing hormone (LH), total testosterone (TT), calculated free T (cFT), estradiol, and sex hormone-binding globulin (SHBG) preorchiectomy in 561 patients with TGCC and compared with 561 healthy controls. We calculated TT/LH and cFT/LH ratios and constructed bivariate charts of TT/LH and cFT/LH from the controls. Logistic regression analysis with an abnormal cFT/LH ratio as outcome and clinical stage, tumor size, age, histology, presence of contralateral germ cell neoplasia in situ (GCNIS), and bilateral tumors as covariates was performed. In patients who were negative for human chorionic gonadotropin (hCG) (n = 374), TT (P = .004), cFT (P < .001), TT/LH ratio (P = .003), and cFT/LH ratio (P = .002) were lower than in controls. A total of 95 (25%) and 91 (24%) of hCG-negative patients had abnormal values when using combined evaluation of TT/LH and cFT/LH, respectively. Increasing tumor size, contralateral GCNIS, and increasing age were associated with Leydig cell dysfunction. In patients positive for hCG (n = 187), all reproductive hormones except SHBG were different from controls (P < .001). Patients with TGCC are at increased risk of Leydig cell dysfunction before orchiectomy. Contralateral GCNIS, increasing age, and increasing tumor size are associated with Leydig cell dysfunction. We hypothesize that patients with preexisting Leydig cell dysfunction are at increased risk of testosterone deficiency following treatment. Copyright © 2016 Elsevier Inc. All rights reserved.

    Testicular cancer represents the most curable solid tumor, with a 10-year survival rate of more than 95%. Given the young average age at diagnosis, it is estimated that effective treatment approaches, in particular, platinum-based chemotherapy, have resulted in an average gain of several decades of life. This success, however, is offset by the emergence of considerable long-term morbidity, including second malignant neoplasms, cardiovascular disease, neurotoxicity, nephrotoxicity, pulmonary toxicity, hypogonadism, decreased fertility, and psychosocial problems. Data on underlying genetic or molecular factors that might identify those patients at highest risk for late sequelae are sparse. Genome-wide association studies and other translational molecular approaches now provide opportunities to identify testicular cancer survivors at greatest risk for therapy-related complications to develop evidence-based long-term follow-up guidelines and interventional strategies. We review research priorities identified during an international workshop devoted to testicular cancer survivors. Recommendations include 1) institution of lifelong follow-up of testicular cancer survivors within a large cohort setting to ascertain risks of emerging toxicities and the evolution of known late sequelae, 2) development of comprehensive risk prediction models that include treatment factors and genetic modifiers of late sequelae, 3) elucidation of the effect(s) of decades-long exposure to low serum levels of platinum, 4) assessment of the overall burden of medical and psychosocial morbidity, and 5) the eventual formulation of evidence-based long-term follow-up guidelines and interventions. Just as testicular cancer once served as the paradigm of a curable malignancy, comprehensive follow-up studies of testicular cancer survivors can pioneer new methodologies in survivorship research for all adult-onset cancer.

    Most testicular germ cell tumors originate from carcinoma in situ cells in fetal life, possibly related to sex hormone imbalances in early pregnancy. Previous studies of association between gestational age at birth and testicular cancer have yielded discrepant results and have not examined extreme preterm birth. Our objective was to determine whether low gestational age at birth is independently associated with testicular cancer in later life. We conducted a national cohort study of 354,860 men born in Sweden in 1973–1979, including 19,214 born preterm (gestational age testicular cancer incidence through 2008. A total of 767 testicular cancers (296 seminomas and 471 nonseminomatous germ cell tumors) were identified in 11.2 million person-years of follow-up. Extreme preterm birth was associated with an increased risk of testicular cancer (hazard ratio 3.95; 95% CI, 1.67–9.34) after adjusting for other perinatal factors, family history of testicular cancer, and cryptorchidism. Only five cases (three seminomas and two nonseminomas) occurred among men born extremely preterm, limiting the precision of risk estimates. No association was found between later preterm birth, post-term birth, or low or high fetal growth and testicular cancer. These findings suggest that extreme but not later preterm birth may be independently associated with testicular cancer in later life. They are based on a small number of cases and will need confirmation in other large cohorts. Elucidation of the key prenatal etiologic factors may potentially lead to preventive interventions in early life. PMID:22314417

    CENP-R is a component of the CENP-O complex, including CENP-O, CENP-P, CENP-Q, CENP-R, and CENP-U and is constitutively localized to kinetochores throughout the cell cycle in vertebrates. CENP-R-deficient chicken DT40 cells are viable and show a very minor effect on mitosis. To investigate the functional roles of CENP-R in vivo, we generated CENP-R-deficient mice (Cenp-r -/- ). Mice heterozygous or homozygous for Cenp-r null mutation are viable and healthy, with no apparent defect in growth and morphology, indicating Cenp-r is not essential for normal development. Accordingly, to investigate the role of the Cenp-r gene in skin carcinogenesis, we subjected Cenp-r -/- mice to the 7,12-dimethylbenz(a)anthracene (DMBA)/TPA chemical carcinogenesis protocol and monitored tumor development. As a result, Cenp-r -/- mice initially developed significantly more papillomas than control wild-type mice. However, papillomas in Cenp-r -/- mice showed a decrease of proliferative cells and an increase of apoptotic cells. As a result, they did not grow bigger and some papillomas showed substantial regression. Furthermore, papillomas in Cenp-r -/- mice showed lower frequency of malignant conversion to squamous cell carcinomas. These results indicate Cenp-r functions bilaterally in cancer development: during early developmental stages, Cenp-r functions as a tumor suppressor, but during the expansion and progression of papillomas it functions as a tumor-promoting factor. © 2017 The Authors.

    Background Testicular cancer is a rare tumor type accounting for 1% of malignancies in men. It is, however, the most common cancer in young men in Western populations. The incidence of testicular cancer is increasing globally, although a decline in mortality rates has been reported in Western countries. It is important to identify whether the variations in trends observed between populations are linked to genetic or environmental factors. Methods Age-standardized incidence rates and age-standardized mortality rates for testicular cancer were obtained for men of all ages in ten countries from the Americas, Asia, Europe, and Oceania using the Cancer Incidence in Five Continents (CI5plus) and World Health Organization (WHO) mortality databases. The annual percent change was calculated using Joinpoint regression to assess temporal changes between geographical regions. Results Testicular cancer age-standardized incidence rates are highest in New Zealand (7.8), UK (6.3), Australia (6.1), Sweden (5.6), USA (5.2), Poland (4.9), and Spain (3.8) per 100,000 men. India, China, and Colombia had the lowest incidence (0.5, 1.3, and 2.2, respectively) per 100,000 men. The annual percent changes for overall testicular cancer incidence significantly increased in the European countries Sweden 2.4%, (2.2; 2.6); UK 2.9%, (2.2; 3.6); and Spain 5.0%, (1.7; 8.4), Australia 3.0%, (2.2; 3.7), and China 3.5%, (1.9; 5.1). India had the lowest overall testicular cancer incidence −1.7%, (−2.5; −0.8). Annual percent changes for overall testicular cancer mortality rates were decreasing in all study populations, with the greatest decline observed in Sweden −4.2%, (−4.8; −3.6) and China −4.9%, (−6.5; −3.3). Conclusion Testicular cancer is increasing in incidence in many countries; however, mortality rates remain low and most men are cured. An understanding of the risks and long-term side effects of treatment are important in managing men with this disease. PMID:24204171

    The United States Preventive Services Task Force (USPSTF) has recommended against testicular self-examinations (TSE) or clinical examination for testicular cancer screening. However, in this recommendation there was no consideration of the significant fiscal cost of treating advanced disease versus evaluation of benign disease. In this study, a cost-utility validation for TSE was performed. The cost of treatment for an advanced-stage testicular tumor (both seminomatous and nonseminomatous) was compared to the cost of six other scenarios involving the clinical assessment of a testicular mass felt during self-examination (four benign and two early-stage malignant). Medicare reimbursements were used as an estimate for a national cost standard. The total treatment cost for an advanced-stage seminoma ($48,877) or nonseminoma ($51,592) equaled the cost of 313-330 benign office visits ($156); 180-190 office visits with scrotal ultrasound ($272); 79-83 office visits with serial scrotal ultrasounds and labs ($621); 6-7 office visits resulting in radical inguinal orchiectomy for benign pathology ($7,686) or 2-3 office visits resulting in treatment and surveillance of an early-stage testicular cancer ($17,283: seminoma, $26,190: nonseminoma). A large number of clinical evaluations based on the TSE for benign disease can be made compared to the cost of one missed advanced-stage tumor. An average of 2.4 to 1 cost benefit ratio was demonstrated for early detected testicular cancer versus advanced-stage disease. © 2014 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Testicular calculus is an extremely rare case with unknown etiology and pathogenesis. To our knowledge, here we report the third case of testicular calculus. A 31-year-old man was admitted to our clinic with painful solid mass in left testis. After diagnostic work-up for a possible testicular tumour, he underwent inguinal orchiectomy and histopathologic examination showed a testicular calculus. Case hypothesis: Solid testicular lesions in young adults generally correspond to testicular cancer. Differential diagnosis should be done carefully. Future implications: In young adults with painful and solid testicular mass with hyperechogenic appearance on scrotal ultrasonography, testicular calculus must be kept in mind in differential diagnosis. Further reports on this topic may let us do more clear recommendations about the etiology and treatment of this rare disease.

    2015-01-01

    Full Text Available Testicular varicocele, a dilation of the veins of the pampiniform plexus thought to increase testicular temperature via venous congestion, is commonly associated with male infertility. Significant study has clarified the negative impact of varicocele on semen parameters and more recent work has shed light on its detrimental effects on the molecular and ultrastructural features of sperm and the testicular microenvironment, as well as more clearly defined the positive impacts of treatment on couples′ fertility. The relationship between varicocele and testicular endocrine function, while known for some time based on histologic evaluation, has become more apparent in the clinical setting with a growing link between varicocele and hypogonadism. Finally, in the pediatric setting, while future study will clarify the impact of varicocele on fertility and testicular function, recent work supports a parallel effect of varicocele in adolescents and adults, suggesting a re-evaluation of current treatment approaches in light of the progressive nature of the condition and potential increased risk of future disease.

    The advances seen in the treatment of testicular cancer are among the great achievements in modern medicine. These advances were made possible by the collaborative efforts of cancer researchers around the world. Investigators have been able to address many questions regarding the treatment of patients with disease limited to the testis, those with metastasis to the retroperitoneum only, and those with advanced metastatic disease. Questions answered include the chemotherapeutic agents to be used and in what combinations, the proper intensity of treatment and appropriate dosing, the optimal number of cycles of chemotherapy according to validated risk stratification, appropriate surgical approaches that preserve sexual function, the treatment of relapsed disease, what supportive care measures to take, and survivorship issues following treatment of testicular cancer. Today, cure is achievable in 95% of all patients with testicular cancer and 80% of those who have metastatic disease. Despite remarkable results with frontline and salvage combination chemotherapy, metastatic testicular cancer remains incurable in approximately 10% of patients, and novel treatment approaches are warranted. This review highlights past and recent discoveries in the treatment of patients with testicular cancer.

    Radionuclide testicular angiography and static imaging is an easy, rapidly performed study. Its usefulness in separating acute testicular torsion from acute epididymitis has been confirmed. Increased angiographic perfusion with definition of the testicular and deferential arteries in the spermatic cord and the pudendal artery posteriorly is equated with inflammation. Intense increased vascularity on the blood pool image is seen in abscess and acute inflammation, while cases of tumor and trauma have mild increases. Acute or missed testicular torsion, uncomplicated hydroceles, and spermatoceles show absent vascularity. On the static images, decreased activity is characteristic of the shape and location of the avascular structure. Technical factors are stressed

    Testicular cancer and infertility affect a similar age group of patients and have common biologic, epidemiologic, and environmental backgrounds. In this review, we provide current literature on links between infertility and testicular cancer, and new developments in the management of testicular cancer aimed at improving quality of life in men with testicular cancer. In-utero environmental exposure to endocrine disruptors modulates the genetically determined fate of primitive gonad and results in testicular dysgenesis syndrome, which may result in infertility and testicular cancer. Excellent response of testicular cancer to radiation and chemotherapy results in over 90% of survival and quality of life--fertility and sexual function--is of significant concern to patients and clinicians. The testicular-sparing management of testicular masses emerges as a sound alternative to radical orchiectomy and allows for preservation of spermatogenesis and hormonal function, and at the same time achieving similar survival rates. Secondary malignancies, pulmonary, and cardiovascular complications are recognized as late complications of treatment for testicular cancer. Better understanding of common mechanisms involved in infertility and testicular cancer, and scientifically driven evidence-based treatment options should improve quality of life in young men faced with this potentially life-threatening disease.

    Testicular cancer (TC) is one of the most common neoplasms that occurs in male and includes germ cell tumors (GCT), sex cord-gonadal stromal tumors and secondary testicular tumors. Diagnosis of TC involves the evaluation of serum tumor markers alpha-fetoprotein, human chorionic gonadotropin and lactate dehydrogenase, but clinically several types of immunohistochemical markers are more useful and more sensitive in GCT, but not in teratoma. These new biomarkers are genes expressed in primordial germ cells/gonocytes and embryonic pluripotency-related cells but not in normal adult germ cells and they include PLAP, OCT3/4 (POU5F1), NANOG, SOX2, REX1, AP-2γ (TFAP2C) and LIN28. Gene expression in GCT is regulated, at least in part, by DNA and histone modifications, and the epigenetic profile of these tumours is characterised by genome-wide demethylation. There are different epigenetic modifications in TG-subtypes that reflect the normal developmental switch in primordial germ cells from an under- to normally methylated genome. The main purpose of this review is to illustrate the findings of recent investigations in the classification of male genital organs, the discoveries in the use of prognostic and diagnostic markers and the epigenetic aberrations mainly affecting the patterns of DNA methylation/histone modifications of genes (especially tumor suppressors) and microRNAs (miRNAs).

    Full Text Available Introduction: Testicular cancer is the most common malignancy in men aged 15–40 years [Bols et al.: Philadelphia, Wolters Kluwer, Lippincott Williams & Wilkins, 2011]. Its incidence comprises 0.8% of all male cancers worldwide, with a mortality rate of 0.1%. The incidence has nearly doubled from 1975 to 2007 leading to the concern of environmental causes [Thomas: Am J Epidemiol 2013; 178: 1240–1245]. Testicular cancer presents as a painless testicular mass without transillumination. Testicular cancer is subcategorized under germ cell testicular cancer or sex cord-stromal tumors. Of the germ cell tumors, approximately 90% originate in the testis, with the other 10% being extragonadal [Bols et al.: Philadelphia, Wolters Kluwer, Lippincott Williams & Wilkins, 2011]. Typically, if a patient presents with a testicular mass and is 50 years old or older, the diagnosis of a primary lymphoma is considered until proven otherwise [Bols et al.: Philadelphia, Wolters Kluwer, Lippincott Williams & Wilkins, 2011]. Germ cell testicular cancer is further divided into the subtypes of seminomatous and nonseminomatous; each presents with a unique histology and differing treatment implications. Discussion: Given the uniqueness of our patient’s metachronous second testicular primary, we sought to compare our case findings to available historic publications. We sought to address the issues of the incidence of a second primary testicular malignancy with regard to varying histology, age of incidence, and timing of a second primary testicular cancer, the presence of bowel involvement, and finally a brief discussion of testosterone replacement therapy. Conclusion: A review of our case presents several unique factors. The above varying literature has shown our patient to have met the odds of a contralateral testicular primary development in that he had a nonseminomatous primary, followed by a second testicular primary seminoma. Our patient exceeded the 15-year

    Wilms tumor is the most common renal tumor in children Synchronous bilateral Wilms tumor (BWT) accounts for 5% of all patients registered to the National Wilms Tumor Study Group (NWSTG). A 28-year-old female patient was presented to Oncology Institute with right kidney tumor. Her left kidney was resected due to Wilms tumor in the sixth month of her life. Abdominal ultrasound was performed and demonstrated a massive right kidney tumor. Then the abdominal CT was undertaken with the use of 16-slice CT scanner, revealing rotation displacement of the right kidney, with signs of compensative overgrowth and displaced upwards. In the lower and peripheral part of the kidney a nodular mass 7 X 10 X 9 cm in size was visible. The tumor was well-demarcated, showing heterogeneous contrast enhancement, extending from the inferio-lateral renal pole.The tumor was adjacent to iliopsoas muscle and abdominal cavity walls; no infiltration of those structures was noted. Described lesion surrounded inferio-medial part of the kidney, approaching kidney pelvis without infiltrating them. Supero-anterior and medial part of the kidney showed normal structure with correct contrasted urine excretion. Lymph nodes enlargement within periaortal area was not detected. Surgical procedure was performed resulting in excision of the tumor with kidney preservation. Histopathology examination revealed nephroblastoma. The tumor was surrounded by a thin, fibrous capsule. Surrounding parenchyma and far tissue were not involved. The CT examination performed 4 months after nephron sparing surgery revealed: right kidney of 137 X 51 mm in size, normally located, with correct structure and function. Multislice abdominal CT have clearly visualized the tumor of the single kidney, showing precise localization of the mass with relation to the kidney pelvis and vessels, allowing for nephron sparing surgical excision.

    The management of acute scrotal swelling can be challenging in neonatal age, with scrotal infections being great mimickers of testicular torsion. Only a few unilateral cases of scrotal abscess have been previously reported, mostly caused by Staphylococcus and Salmonella. We describe the case of a newborn who developed bilateral scrotal abscesses caused by Klebsiella pneumoniae and discuss the rarity of the case, regarding both the bilaterality and the pathogen, never reported before.

    The nationwide Danish Testicular Cancer database consists of a retrospective research database (DaTeCa database) and a prospective clinical database (Danish Multidisciplinary Cancer Group [DMCG] DaTeCa database). The aim is to improve the quality of care for patients with testicular cancer (TC) in Denmark, that is, by identifying risk factors for relapse, toxicity related to treatment, and focusing on late effects. All Danish male patients with a histologically verified germ cell cancer diagnosis in the Danish Pathology Registry are included in the DaTeCa databases. Data collection has been performed from 1984 to 2007 and from 2013 onward, respectively. The retrospective DaTeCa database contains detailed information with more than 300 variables related to histology, stage, treatment, relapses, pathology, tumor markers, kidney function, lung function, etc. A questionnaire related to late effects has been conducted, which includes questions regarding social relationships, life situation, general health status, family background, diseases, symptoms, use of medication, marital status, psychosocial issues, fertility, and sexuality. TC survivors alive on October 2014 were invited to fill in this questionnaire including 160 validated questions. Collection of questionnaires is still ongoing. A biobank including blood/sputum samples for future genetic analyses has been established. Both samples related to DaTeCa and DMCG DaTeCa database are included. The prospective DMCG DaTeCa database includes variables regarding histology, stage, prognostic group, and treatment. The DMCG DaTeCa database has existed since 2013 and is a young clinical database. It is necessary to extend the data collection in the prospective database in order to answer quality-related questions. Data from the retrospective database will be added to the prospective data. This will result in a large and very comprehensive database for future studies on TC patients.

    Full Text Available Introduction: The incidence of benign testicular tumors is increasing in particular in small lesion incidentally found at scrotal ultrasonography. Primary aim of this study was to perform radical surgery in malignant tumor. Secondary aim was to verify the efficacy of the diagnostic-therapeutic pathway recently adopted in management of small masses with testis sparing surgery in benign lesions. Materials and methods: In this multicenter study, we reviewed all patients with single testis lesion less than 15 mm at ultrasound as main diameter. We applied the diagnostic-therapeutic pathway described by Sbrollini et al. (Arch Ital Urol Androl 2014; 86:397 which comprises: 1 testicular tumor markers, 2 repeated scrotal ultrasound at the tertiary center, 3 surgical exploration with inguinal approach, intraoperative ultrasound, and intraoperative pathological examination. Definitive histology was reviewed by a dedicated uro-pathologist. Results: Twenty-eight patients completed this clinical flowchart. The mean lesion size was 9.3 mm (range 2.5-15. Testicular tumor markers were normal except in a case. Intraoperative ultrasound was necessary in 8/28 cases. We treated 11/28 (39.3% with immediate radical orchiectomy and 17/28 (60.7% with testis-sparing surgery. Definitive pathological results were: malignant tumor in 6 cases (seminoma, benign tumor in 10 cases (5 Leydig tumors, 2 Sertoli tumors, 1 epidermoid cyst, 1 adenomatoid tumor, 1 angiofibroma, benign disease in 11 (8 inflammation with haemorragic infiltration, 2 tubular atrophy, 1 fibrosis, and normal parenchyma in 1 case. We observed a good concordance between frozen section examination and definitive histology. Any malignant tumor was treated conservatively. Any delayed orchiectomy was necessary based on definitive histology. Conclusions: The incidence of benign lesions in 60% of small testis lesions with normal tumor markers makes orchiectomy an overtreatment. Testicular sparing surgery of single

    No consensus exists regarding the precise role of testicular biopsy in prepubertal boys, although it is considered useful for assessing the potential consequences of undescended testes on fertility. Current scientific knowledge indicates that surgeons should broaden indications for this procedure...... for the preservation of fertility after gonadotoxic chemotherapy - even for prepubertal boys - are emerging. Cryopreservation of testicular tissue samples for the preservation of fertility - although still an experimental method at present - is appealing in this context.

    To describe the pathophysiologic mechanisms, histologic and clinical staging, diagnosis, and medical and nursing management of testicular cancer. Published studies, review articles, and Physician Data Query database. Testicular cancer is a complex disease resulting from transformation of gonadal tissues. The pathophysiologic mechanisms involve damage to tissue in utero and after birth. Orchiectomy is the treatment of choice for early-stage disease. Orchiectomy can have profound physiologic and psychological consequences for young males. Subsequent chemotherapy and radiation therapy also may have severe side effects including azoospermia, bone marrow suppression, nephrotoxicity, and pulmonary toxicity. Early detection of this disease results in improved patient outcomes. Patients treated with radical inguinal orchiectomy and radiation therapy have fewer long-term side effects and toxicities than patients who require more extensive surgery and chemotherapy. Nursing care must focus not only on relieving the patient's physical symptoms but on helping him deal with the psychosexual issues associated with the disease and its treatment.

    Inverted papilloma (IP) is a benign tumor of the nasal cavity and paranasal sinuses that is unilateral in most cases. Bilateral IP, involving both sides of the nasal cavity and sinuses, is extremely rare. This paper describes a large IP that filled in both sides of the nasal cavity and sinuses, mimicking association with malignancy. The tumor was successfully treated by bilateral endoscopic medial maxillectomy (EMM). The patient is without evidence of the disease 24 months after surgery. If preoperative diagnosis does not confirm the association with malignancy in IP, endoscopic sinus surgery (ESS) should be selected, and ESS, including EMM, is a good first choice of the treatment for IP.

    Full Text Available Testicular cancer is the most common solid malignancy affecting males between the ages of 15 and 35. The symptomatology caused by this tumor varies according to the site of metastasis. We present the case of a 26-year-old male who arrived to the emergency department with hematemesis. He had no previous medical history. On arrival, we noted enlargement of the left scrotal sac. There was also a mass in the left scrotum which provoked displacement of the penis and right testis. The serum alpha-fetoprotein level was 17,090 ng/mL, lactate dehydrogenase was 1480 U/L, and human chorionic gonadotropin was 287.4 IU/mL. Upper endoscopy revealed a type 1 isolated gastric varix, treated with cyanoacrylate. A CT scan showed extrinsic compression of the portal vein by lymphadenopathy along with splenic vein partial thrombosis, which caused left-sided portal hypertension. Neoadjuvant chemotherapy was started with etoposide and cisplatin, and seven days later the patient underwent left radical orchiectomy. A postoperative biopsy revealed a pure testicular teratoma. Noncirrhotic left portal hypertension with bleeding from an isolated gastric varix secondary to metastasic testicular cancer has not been described before. Clinicians must consider the possibility of malignancy in the differential diagnosis of a young man presenting with unexplained gastrointestinal bleeding.

    Full Text Available Klinefelter syndrome (KS is a hypergonadotropic hypogonadism characterized by a 47, XXY karyotype. The risk of testicular cancer in KS is of interest in relation to theories about testicular cancer etiology generally; nevertheless it seems to be low. We evaluated the need for imaging and serum tumor markers for testicular cancer screening in KS. Participants were 40 consecutive KS patients, enrolled from December 2009 to January 2013. Lactate dehydrogenase (LDH, alpha-fetoprotein (AFP, and beta-human chorionic gonadotrophin subunit (β-HCG serum levels assays and testicular ultrasound (US with color Doppler, were carried out at study entry, after 6 months and every year for 3 years. Abdominal magnetic resonance (MR was performed in KS when testicular US showed micro-calcifications, testicular nodules and cysts. Nearly 62% of the KS had regular testicular echotexture, 37.5% showed an irregular echotexture and 17.5% had micro-calcifications and cysts. Eighty seven percent of KS had a regular vascular pattern, 12.5% varicocele, 12.5% nodules 1 cm. MR ruled out the diagnosis of cancer in all KS with testicular micro calcifications, nodules and cysts. No significant variations in LDH, AFP, and β-HCG levels and in US pattern have been detected during follow-up. We compared serum tumor markers and US pattern between KS with and without cryptorchidism and no statistical differences were found. We did not find testicular cancer in KS, and testicular US, tumor markers and MR were, in selected cases, useful tools for correctly discriminating benign from malignant lesions.

    2016-07-01

    To perform a systematic literature review to assess whether the occurrence of testicular microlithiasis (TML) in conjunction with other risk factors is associated with testicular cancer. A systematic literature search was performed of original articles in English published 1998 to 2015. Relevant studies were selected by reading the title and abstract by two of the authors. Studies were included if TML was diagnosed by ultrasonography and a risk condition was reported. Studies were only eligible if the particular risk condition was reported in more than one article. In total, 282 abstracts in were identified. Based on title and abstract the eligibility was assessed and 31 studies were included. Five conditions in relation to TML and testicular cancer emerged: Down syndrome, McCune-Albright syndrome, cryptorchidism, infertility and familial disposition of testicular cancer. Data support the conclusion that TML is not an independent risk factor for testicular cancer but associated with testicular cancer through other conditions. In male infertility, TML appears to be related to an increased risk of testicular cancer possibly as part of a testicular dysgenesis syndrome.

    2018-03-01

    Full Text Available Introduction: Acute testicular pain is frequent in urology. If torsion of the spermatic cord and orchiepididymites are usual, thrombosis of the pampiniform plexus is a very uncommon clinical entity. We present an unusual case and review the literature to explore potential etiologies and therapeutic strategies. Observation: A rare case of bilateral thrombosis of the pampiniform plexus occurred in a 39 year-old male.The diagnosis was confirmed with doppler sonographie and Computer Tomography. Urethral infection and protein C deficiency were found as associated factors. The treatment was conservative with good result. Conclusions: Anatomical factors are probably responsible for almost exclusive involvement of the left side. However, coagulation abnormalities and retroperitoneal tumors or absence of inferior vena cava must be sought especially in cases of right side or bilateral thrombosis of the pampiniform plexus. The management of pampiniform plexus thrombosis remains non surgical based on symptomatic treatment with good clinical and radiological evolution.

    Full Text Available Most retroperitoneal tumors such as renal cell carcinoma have been associated with tumor thrombus extending into the renal vein, inferior vena cava (IVC, and heart. The retroperitoneal metastatic potential of testicular tumors is well known. We report here the first instance of a cardiac murmur prompting diagnosis of metastatic testicular neoplasia in an 18-year-old patient. Chemotherapy was delayed and after successful surgical resection of the ventricular mass, the patient recovered uneventfully. This case underscores the need to pursue abnormal cardiac exams in newly diagnosed testicular cancer patients.

    1985-01-01

    Current practice for achieving local control of testicular relapse in males with acute lymphoblastic leukemia (ALL) includes the use of 2,400-rad testicular radiation. Although this therapy is known to cause germ cell depletion, it has been assumed that it does not alter testicular secretion of testosterone. To test this assumption, the authors measured gonadotropin and testosterone levels in seven boys with ALL who had been treated with radiation for clinically apparent testicular relapse. In four of seven boys, testicular relapse was bilateral with overt involvement of one testicle and microscopic involvement of the other. Three of these four boys demonstrated delayed sexual maturation, and in addition to elevated follicle-stimulating hormone (FSH) concentrations, testosterone levels were low and luteinizing hormone levels were elevated compared with controls. These data indicate that boys with overt testicular leukemia who are treated with 2,400-rad testicular radiation are at risk for Leydig cell dysfunction. However, the relative contributions of radiation, prior chemotherapy, and leukemic infiltration to this dysfunction remain to be clarified

    2017-01-01

    There is a paucity of data regarding testicular cancer among Saudis as well as the nonexistent of published national data. Furthermore, a substantial increase of the incidence of testicular cancer among Saudis was lately noted. The aim of the study is to determine the trends and patterns of testicular cancer among adult Saudis using national data over a period of 20 years. The national database of the Saudi Cancer Registry (SCR) on testicular cancer over the last two decades was studied including epidemiological and histological patterns. The 1004 cases of testicular cancer among adult Saudis reported by the SCR will be the subject of this study. From 1994 to 2013, 1004 cases of testicular cancer among adult Saudis were reported to the SCR, with a steadily significant increase in incidence rate reaching an annual rate of 94 cases in 2013. Age of the patients ranged 15-93 years with a mean of 34.5 years. The most affected age group was 20-34 years, where 51% of all testicular cancer accumulated. Around 85% of testicular cancer is germ cell tumors, while paratesticular and gonadal stromal tumors represent 15%. Of all testicular cancer, seminomas were seen in 40.7%, nonseminomas in 44.6%. Notably, 70.4% of the cases in the first decade were seminomas, while in the second decade 65.9% of the cases were nonseminomas. The subtypes of the nonseminomas were a mixed tumor in 51.6%, embryonal carcinoma in 19.9%, yolk sac tumor in 12.3%, germinomas in 6.7%, teratomas in 6%, and choriocarcinomas in 3.6%. Lymphomas (34.7%) and rhabdomyosarcomas (23.6%) are on the top of the paratesticular tumor group. The Surveillance Epidemiology and End Results summary stage of seminomas was localized in 61.6%, regional in 19.8%, and distant in 12.6%, while of nonseminomas was 48%, 15.5%, and 28.5%, respectively. Localized and distant status of seminomas improved over the studied period by 12% and 4% respectively, while this trend was not seen in nonseminomas. The incidence rate is on rising

    To determine whether initial ligation of the testicular vessels of the high undescended testis followed by a delayed secondary orchiopexy is a viable alternative to the classical Fowler-Stephens procedure, a series of preliminary experiments were conducted in the rat in which testicular blood flow was measured by the 133-xenon washout technique before, and 1 hour and 30 days after ligation of the vessels. In addition, testicular histology, and testis and sex-accessory tissue weights were measured in 6 control, 6 sham operated and 6 testicular vessel ligated rats 54 days after vessel ligation. The data demonstrate that ligation and division of the testicular blood vessels produce an 80 per cent decrease in testicular blood flow 1 hour after ligation of the vessels. However, 30 days later testis blood flow returns to the control and pre-treatment value. There were no significant changes in testis or sex-accessory tissue weights 54 days after vessel ligation. Histologically, 4 of the surgically operated testes demonstrated necrosis of less than 25 per cent of the seminiferous tubules while 1 testis demonstrated more than 75 per cent necrosis. The rest of the tubules in all 6 testes demonstrated normal spermatogenesis. From this study we conclude that initial testicular vessel ligation produces an immediate decrease in testicular blood flow but with time the collateral vessels are able to compensate and return the testis blood flow to its normal pre-treatment value. These preliminary observations lend support for the concept that initial ligation of the testicular vessels followed by a delayed secondary orchiopexy in patients with a high undescended testis may be a possible alternative to the classical Fowler-Stephens approach

    Full Text Available Pediatric testicular cancer is exceedingly rare. There are no data available touching Saudi children. The aim of the study is to determine the trends and patterns of testicular cancer among Saudi children over a period of 20 years. The national database of the Saudi Cancer Registry (SCR on pediatric testicular cancer over the last two decades was examined including epidemiological and histological patterns. From 1994 to 2013, 82 cases of testicular cancer among Saudi children aged 1–14 years were accumulated at the SCR. The annual percentage change rate was 3.3%. Of all cases, 62% appeared within the first 2 years of life. Seminomas were seen in 39%, nonseminomas in 40.3%, and paratesticular tumors in 20.7%. No gonadal stromal tumors observed. About 91% of the seminomas accrued in the first decade (1994–2003, while all nonseminomas fell in the last decade (2004–2013. The most common subtypes of the nonseminomas were yolk sac tumors and mixed tumors. More than 80% of the paratesticular tumors were rhabdomyosarcomas and lymphomas. The SEER summary stage of seminomas was localized in 56%, regional in 22%, and distant in 16%, while of nonseminomas was 56%, 16%, and 28%, respectively, and no stage improvement over the studied period was noted. No temporal trend in incidence rate was observed. The most affected age group was the first 2 years of life. Noteworthy was the high incidence of seminoma and the low rate of teratomas and stromal tumors, when compared to Western data. Notable was the dominance of the seminomas in the first decade and of the nonseminomas in the second decade. At the time of diagnosis, nonseminomas were more advanced than seminomas. No stage improvement noted over the studied period.

    Testicular benign tumors are very rare (< 5%). Testicular Angiofibroma (AF) is one of those, however the gold standard of treatment and follow-up is still unclear. A 47 years-old man with only one functioning testis was referred to our clinic for a palpable right testicular mass and atrophic contralateral testis. Patient underwent testis-sparing surgery with inguinal approach and intraoperative frozen sections examination with diagnosis of AF. Final histology confirmed AF. Post-operative follow-up was uneventful. Clinical and ultrasonographic follow-up was negative after 8 months. We report a conservative surgery in a patient with AF of the solitary testis. AF is a benign para-testicular fibrous neoplasm that could be misinterpreted as malignant tumor and treated with orchiectomy. Testis-sparing surgery is recommended in this case with intraoperative pathological examination. The excision of the mass is enough but in front of a possible recurrence a long follow-up is advisable.

    Full Text Available Abstract Background Late relapses of testicular germ cell tumor are uncommon. We report a case of cervical mature teratoma appeared 17 years after treatment of testicular teratocarcinoma. Case presentation A 20- year- old patient underwent left sided orchiectomy followed by systemic therapy and retroperitoneal residual mass resection in 1989. He remained in complete remission for 200 months. In 2005 a huge left supraclavicular neck mass with extension to anterior mediastinum appeared. Radical surgical resection of the mass was performed and pathologic examination revealed mature teratoma. Conclusion This is one of the longest long-term reported intervals of a mature teratoma after treatment of a testicular nonseminoma germ cell tumor. This case emphasizes the necessity for follow up of testicular cancer throughout the patient's life.

  17. Testicular Volume: Size Does Matter

    Testicular volume is critical for semen production and, consequently, for fertility. Hence the importance of knowing the normal size ranges and the different methods for calculating size, in order to classify patients at risk and refer them for appropriate management. Ultrasound is the first-line diagnostic method for the evaluation of testicular pathology, and it is also the best tool for estimating the volume of both testicles, bearing in mind that a testicular volume below 15 cc results in fertility problems. Although there are many causes of infertility, varicocele is undoubtedly the most important of all, because of its frequency and because it is amenable to curative surgical treatment.

    Full Text Available Metastasis of prostate carcinoma to the testis is seldom reported. The tumour may spread from the prostatic urethra by retrograde venous extension, arterial embolism or through direct invasion into the lymphatics and lumen of the vas deferens. Clinical manifestations of secondary testicular tumours from the prostate are most often unsuspected clinically and are instead detected incidentally during orchidectomy. Less frequently, a palpable mass is detected, which may be confused with a primary testicular neoplasm. We report a case of a 66-year-old patient with adenocarcinoma of the prostate, and a left testicular tumour that was diagnosed as metastases from prostate carcinoma after radical orchidectomy.

    Gynecomastia in a 20-years-old male is reported. At the age of 2, the patients had contracted acute lymphocytic leukemia (ALL), at which time irradiation for the testicular ALL invasion was performed. This irradiation induced atrophy of the testis. Obesity was first noted when he was 12 years old, after which enlargement of the bilateral breasts occurred at 14 years of age. When he turned 19, supplementary testosterone therapy was initiated to counter the gynecomastia, but it proved ineffective. Thus, a total mastectomy was performed with free nipple grafting. Pathologically, inspected mammary tissue specimens revealed mammary ducts in a fibrous stroma that had encompassed lobules of adipose tissue. The findings in this case suggest that the testicular irradiation had induced primary hypogonadism and that this had resulted in gynecomastia and obesity. (author)

    {sup 18}F-FDG PET has a higher diagnostic accuracy than CT in initial staging of testicular cancer. In seminoma, it can discriminate residual tumor from necrosis/fibrosis or mature teratoma. {sup 18}F-FDG PET is also useful for the response evaluation of chemotherapy. However, there's no clinical evidence for the use of {sup 18}F-FDG PET in the diagnosis and differential diagnosis of testicular cancer.

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

    The value of CT and lymphography of the retroperitoneum was compared in 31 patients with testicular tumors. In no patient with normal or equivocal lymphography was more information gained by CT. In abnormal cases, the presence of metastatic deposits was well detected at both examinations, but CT proved more useful in defining the exact extent of the tumor and facilitated the proper arrangement of the irradiation fields. A strategy in the sequence of investigation in testicular tumors is suggested, aiming to save CT time when CT information is not likely to be of significance for treatment planning.

    Germ-cell tumours (GCTs) are the most common type of cancer in young men. Since the late 1970s, disseminated GCT have been a paradigm for curable metastatic cancer and metastatic GCTs are highly curable with cisplatin-based chemotherapy followed by surgical resection of residual masses. Patients' prognosis is currently assessed using the International Germ-Cell Consensus Classification (IGCCC) and used to adapt the burden of chemotherapy. Approximately 20% of patients still do not achieve cure after first-line cisplatin-based chemotherapy, and need salvage chemotherapy (high dose or standard dose chemotherapy). Clinical stage I testicular cancer is the most common presentation and different strategies are proposed: adjuvant therapies, surgery or surveillance. During the last three decades, clinical trials and strong international collaborations lead to the development of a consensus in the management of GCTs.

    Full text: The HRAD9 gene mediates radioresistance and regulates the G2/M cell cycle checkpoint induced by ionizing radiation. In this report, we describe the isolation of the human paralog of HRAD9, called HRAD9B. Furthermore, we demonstrate that, like HRAD9 protein, the HRAD9B gene product can coimmunoprecipitate with HRAD1, HRAD9, HHUS1 and HHUS1B proteins. However, HRAD9B is expressed predominantly in testis, whereas its paralog is expressed more universally in different tissues. And most notably, we demonstrate that HRAD9B exhibits markedly and consistently reduced expression in testicular seminomas, high levels of expression in normal adult testis, yet also shows expression in fetal testis cells where meiosis is not performed. These results suggest that HRAD9B could at the least serve as a marker for testicular cancer, and its expression may be causally related to the disease. Further studies are under way to determine the cause of the reduced expression of HRAD9B in germ cell tumors

    A 45 year-old-man was admitted to our hospital because of discomfort in his left scrotum. He had a left testicular tumor. We performed high orchiectomy and pathological findings revealed testicular cancer. He was treated with bleomycin, etoposide and cisplatin. Computed tomography showed a new mass in the left lung after 3 cycles of the chemotherapy. Because of its rapid growth, the tumor was thought to be a metastasis lesion of testicular cancer or pulmonary infection. Transbronchial lung biopsy showed an invasion of multinucleated giant cells and granuloma. The culture and polymerase chain reaction of the bronchial sputum were positive for myobacterium avium-complex (MAC). From these findings, the left lung tumor was diagnosed as pulmonary MAC disease. He received partial resection of the left lung and the lesion was diagnosed as granuloma. There was no recurrence of testicular cancer or pulmonary disease after the surgery.

    Full Text Available Inverted papilloma (IP is a benign tumor of the nasal cavity and paranasal sinuses that is unilateral in most cases. Bilateral IP, involving both sides of the nasal cavity and sinuses, is extremely rare. This paper describes a large IP that filled in both sides of the nasal cavity and sinuses, mimicking association with malignancy. The tumor was successfully treated by bilateral endoscopic medial maxillectomy (EMM. The patient is without evidence of the disease 24 months after surgery. If preoperative diagnosis does not confirm the association with malignancy in IP, endoscopic sinus surgery (ESS should be selected, and ESS, including EMM, is a good first choice of the treatment for IP.

    As diagnosed by ultrasonography, testicular microlithiasis is associated with various benign and malignant conditions. The molecular constitution of these microliths is largely unknown. Raman spectroscopy provides detailed in situ information about the molecular composition of tissues and to our knowledge it has not been applied to gonadal microliths. We analyzed the molecular composition of gonadal microlithiasis and its surrounding region using Raman spectroscopy in malignant and benign conditions. Multiple microliths from 6 independent samples diagnosed with gonadal microlithiasis by ultrasound and histologically confirmed were investigated by Raman spectroscopy. The samples included 4 testicular parenchyma samples adjacent to a germ cell tumor (4 seminomas), a gonadoblastoma of a dysgenetic gonad and testicular biopsy of a subfertile male without malignancy. Raman spectroscopic mapping demonstrated that testicular microliths were located within the seminiferous tubule. Glycogen surrounded all microliths in the samples associated with germ cell neoplasm but not in the benign case. The molecular composition of the 26 microliths in all 6 conditions was pure hydroxyapatite. Microliths in the testis are located in the seminiferous tubules and composed of hydroxyapatite. In cases of germ cell neoplasm they co-localize with glycogen deposits.

    Full Text Available Testicular microlithiasis is a condition characterized by the ultrasonographic findings with multiple microliths, with the prevalence of 0.6% to 9%. This is a condition of unknown etiology; however, in many cases it may be associated with cryptorchidism, Klinefelter syndrome, Down syndrome, varicocele, testicular torsion and male pseudohermaphroditism. Many retrospective studies point to the association between testicular microlithiasis and testicular cancer.

    Testicular germ cell tumors (TGCT) represent the most common malignant tumor group in the age group of 20 to 40-years old men. The potentially curable effect of cytotoxic therapy in TGCT is mediated mainly by the induction of apoptosis. Autophagy has been discussed as an alternative mechanism of cell death but also of treatment resistance in various types of tumors. However, in TGCT the expression and role of core autophagy-associated factors is hitherto unknown. We designed the study in order to evaluate the potential role of autophagy-associated factors in the development and progression of testicular cancers. Eighty-four patients were assessed for autophagy (BAG3, p62) and apoptosis (cleaved caspase 3) markers using immunohistochemistry (IHC) on tissue micro- arrays. In addition, western blot analyses of frozen tissue of seminoma and non-seminoma were performed. Our findings show that BAG3 was significantly upregulated in seminoma as compared to non-seminoma but not to normal testicular tissue. No significant difference of p62 expression was detected between neoplastic and normal tissue or between seminoma and non-seminoma. BAG3 and p62 showed distinct loco‑regional expression patterns in normal and neoplastic human testicular tissues. In contrast to the autophagic markers, apoptosis rate was significantly higher in testicular tumors as compared to normal testicular tissue, but not between different TGCT subtypes. The present study, for the first time, examined the expression of central autophagy proteins BAG3 and p62 in testicular cancer. Our findings imply that in general apoptosis but not autophagy induction differs between normal and neoplastic testis tissue.

    Pyle, Louise C; Nathanson, Katherine L

    2016-10-01

    Testicular germ cell tumor (TGCT) is a highly heritable cancer primarily affecting young white men. Genome-wide association studies (GWAS) have been particularly effective in identifying multiple common variants with strong contribution to TGCT risk. These loci identified through association studies have implicated multiple genes as associated with TGCT predisposition, many of which are unique among cancer types, and regulate processes such as pluripotency, sex specification, and microtubule assembly. Together these biologically plausible genes converge on pathways involved in male germ cell development and maturation, and suggest that perturbation of them confers susceptibility to TGCT, as a developmental defect of germ cell differentiation.

    De Gendt Karl

    2009-08-01

    Full Text Available Abstract Background Testicular microliths are calcifications found within the seminiferous tubules. In humans, testicular microlithiasis (TM has an unknown etiology but may be significantly associated with testicular germ cell tumors. Factors inducing microlith development may also, therefore, act as susceptibility factors for malignant testicular conditions. Studies to identify the mechanisms of microlith development have been hampered by the lack of suitable animal models for TM. Methods This was an observational study of the testicular phenotype of different mouse models. The mouse models were: cryptorchid mice, mice lacking androgen receptors (ARs on the Sertoli cells (SCARKO, mice with a ubiquitous loss of androgen ARs (ARKO, hypogonadal (hpg mice which lack circulating gonadotrophins, and hpg mice crossed with SCARKO (hpg.SCARKO and ARKO (hpg.ARKO mice. Results Microscopic TM was seen in 94% of hpg.ARKO mice (n = 16 and the mean number of microliths per testis was 81 +/- 54. Occasional small microliths were seen in 36% (n = 11 of hpg testes (mean 2 +/- 0.5 per testis and 30% (n = 10 of hpg.SCARKO testes (mean 8 +/- 6 per testis. No microliths were seen in cryptorchid, ARKO or SCARKO mice. There was no significant effect of FSH or androgen on TM in hpg.ARKO mice. Conclusion We have identified a mouse model of TM and show that lack of endocrine stimulation is a cause of TM. Importantly, this model will provide a means with which to identify the mechanisms of TM development and the underlying changes in protein and gene expression.

To corroborate the hypothesis of a common association of germ cell cancer with testicular...... dysgenesis, microscopic dysgenetic features were quantified in contralateral testicular biopsies in patients with a testicular germ cell tumour. Two hundred and eighty consecutive contralateral testicular biopsies from Danish patients with testicular cancer diagnosed in 1998-2001 were evaluated...... presenting with testicular germ cell neoplasms of the adolescent and young type. The findings therefore support the hypothesis that this cancer is part of a testicular dysgenesis syndrome. The presence of contralateral carcinoma in situ was higher in the present study than previously reported....

  10. Nine cases of nonpalpable testicular mass. An incidental finding in a large scale ultrasonography survey

    2008-01-01

    Nonpalpable testicular masses are usually diagnosed during routine ultrasonography (US) examinations for other conditions. There are conflicting results on the final diagnosis and management of these lesions. In the present study we report the results of a large US series of 5104 patients on nonpalpable testicular masses and discuss the management of these patients. This retrospective observational study was performed in a secondary care military hospital. A total of 5104 patients underwent a US and 11 of them were diagnosed as having a nonpalpable testicular mass. These 11 patients also underwent magnetic resonance imaging (MRI). Two of them refused surgery and were excluded from the study. The remaining nine patients underwent intraoperative US-guided localization and excisional biopsy of the non-palpable testicular parenchymal mass. A radical orchiectomy was required in all of them. US and MRI findings, frozen and final pathology results were recorded. The median age of study subjects was 24 years. The final pathology revealed a malign tumor in eight patients and an inflammatory mass in one patient. There were inconsistent results in four patients between frozen section analysis and final pathology. MRI improved the definition of the solid masses in all patients. MRI enhances the certainty of the diagnosis of malignity in nonpalpable testicular masses, particularly in conditions that generally can not be diagnosed with ultrasonography alone. Frozen section analysis is not an accredited method in diagnosing malign lesions in non-palpable testicular masses. (author)

  11. Protective effect of hemin against cadmium-induced testicular damage in rats

    The protective effect of hemin, the heme oxygenase-1 inducer, was investigated in rats with cadmium induced-testicular injury, in which oxidative stress and inflammation play a major role. Testicular damage was induced by a single i.p. injection of cadmium chloride (2 mg/kg). Hemin was given for three consecutive days (40 μmol/kg/day, s.c.), starting 1 day before cadmium administration. Hemin treatment significantly increased serum testosterone level that was reduced by cadmium. Hemin compensated deficits in the antioxidant defense mechanisms (reduced glutathione, and catalase and superoxide dismutase activities), and suppressed lipid peroxidation in testicular tissue resulted from cadmium administration. Also, hemin attenuated the cadmium-induced elevations in testicular tumor necrosis factor-α and nitric oxide levels, and caspase-3 activity. Additionally, hemin ameliorated cadmium-induced testicular tissue damage observed by light and electron microscopic examinations. The protective effect afforded by hemin was abolished by prior administration of zinc protoporphyrin-IX, the heme oxygenase-1 inhibitor. It was concluded that hemin, through its antioxidant, anti-inflammatory and antiapoptotic effects, represents a potential therapeutic option to protect the testicular tissue from the detrimental effects of cadmium

    2017-11-01

    Full Text Available Summary: Testicular germ cell tumors (TGCTs are among the most responsive solid cancers to conventional chemotherapy. To elucidate the underlying mechanisms, we developed a mouse TGCT model featuring germ cell-specific Kras activation and Pten inactivation. The resulting mice developed malignant, metastatic TGCTs composed of teratoma and embryonal carcinoma, the latter of which exhibited stem cell characteristics, including expression of the pluripotency factor OCT4. Consistent with epidemiological data linking human testicular cancer risk to in utero exposures, embryonic germ cells were susceptible to malignant transformation, whereas adult germ cells underwent apoptosis in response to the same oncogenic events. Treatment of tumor-bearing mice with genotoxic chemotherapy not only prolonged survival and reduced tumor size but also selectively eliminated the OCT4-positive cancer stem cells. We conclude that the chemosensitivity of TGCTs derives from the sensitivity of their cancer stem cells to DNA-damaging chemotherapy. : Using a mouse testicular germ cell tumor model, Pierpont et al. establish that male germ cells are susceptible to malignant transformation during a restricted window of embryonic development. The cancer stem cells of the resulting testicular cancers demonstrate genotoxin hypersensitivity, rendering these malignancies highly responsive to conventional chemotherapy.

    2015-09-01

    Full Text Available The role of sonoelastography in diagnosing cancerous masses has increased since the advent of elastography as an ultrasound modality. Its ability to display differences in the mechanical properties of cancerous masses compared to normal surrounding tissue has shown benefit in increasing the accuracy of diagnosing malignant breast and thyroid masses and has shown early potential in accomplishing better targeted prostate biopsies. To date, the literature is limited in the number of studies describing the use of sonoelastography for testicular masses. We describe a 34-year-old man who presented with an incidental finding of an impalpable hypoechoic testicular mass on grayscale ultrasound during an infertility work-up. Sonoelastography was performed displaying intermediate testicular elastic properties. Upon frozen section of the mass during surgical exploration, classic testicular seminoma was diagnosed and subsequent radical orchiectomy was performed. We would like to use this atypical presentation of testicular seminoma to review the potential role of elastography for diagnosing testicular cancer.

    Science.gov (United States)

    Koskenniemi, Jaakko J; Virtanen, Helena E; Toppari, Jorma

    2017-06-01

    To describe pubertal testicular growth in humans, changes in testicular cell populations that result in testicular growth, and the role of testosterone and gonadotrophins follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in testicular growth. When human data were not available, studies in nonhuman primates and/or rodents were used as surrogates. Testicular growth in puberty follows a sigmoidal growth curve, with a large variation in timing of testicular growth and adult testicular volume. Testicular growth early in puberty is due to increase in Sertoli cell number and length of seminiferous tubules, whereas the largest and fastest growth results from the increase in the diameter of the seminiferous tubules first due to spermatogonial proliferation and then due to the expansion of meiotic and haploid germ cells. FSH stimulates Sertoli cell and spermatogonial proliferation, whereas LH/testosterone is mandatory to complete spermatogenesis. However, FSH and LH/testosterone work in synergy and are both needed for normal spermatogenesis. Testicular growth during puberty is rapid, and mostly due to germ cell expansion and growth in seminiferous tubule diameter triggered by androgens. Pre-treatment with FSH before the induction of puberty may improve the treatment of hypogonadotropic hypogonadism, but remains to be proven.

    2005-09-01

    Testicular cancer is a rare disease, accounting for 1.1% of all malignant neoplasms in Canadian males. Despite the low overall incidence of testicular cancer, it is the most common malignancy among young men. The incidence rate of testicular cancer has been increasing since the middle of the 20th century in many western countries. However, the etiology of testicular cancer is not well understood. A search of the peer-reviewed literature was conducted to identify important articles for review and inclusion in this overview of the epidemiology of testicular cancer. Most of the established risk factors are related to early life events, including cryptorchidism, carcinoma in situ and in utero exposure to estrogens. Occupational, lifestyle, socioeconomic and other risk factors have demonstrated mixed associations with testicular cancer. Although there are few established risk factors for testicular cancer, some appear to be related to hormonal balance at various life stages. Lifestyle and occupational exposures occurring later in life may play a role in promoting the disease, although they are not likely involved in cancer initiation. In addition to summarizing the current epidemiologic evidence on risk factors for testicular cancer, we suggest future research directions that may elucidate the etiology of testicular cancer.

    Testicular cancer is rare, representing only 1 % of malignant tumors, but the most common cancer in young men, 15 to 35 years. Adjuvant radiotherapy after orchidectomy in testicular seminoma stage I, reduces risk of relapse. It aims to eradicate micro-metastatic disease in lymph drainage territories. In the case of adjuvant radiotherapy, the relapse-free survival of 96 % with an overall survival of 98 % at 5 years. The irradiation volume is made up of lymph nodes paraaortic which it is possible to add the ipsilateral renal hilum to the testicular lesion. The current recommended dose is 20 Gy in 10 fractions and 2 weeks, usually delivered by two antero-posterior beams. The acute toxicities, mainly represented by nausea and diarrhea are usually quickly resolved to the end of irradiation. Regarding toxicities long-term, preservation of semen should be considered after surgery because of fear of infertility post-treatment. The risk of second cancer associated with exposure to ionizing radiation, albeit small, is especially important to consider these patients to significant life expectancy. Nevertheless, developments in radiotherapy techniques and lower doses and irradiated volumes can probably reduce this risk further. (authors)

    Full Text Available Pediatric germ cell tumors (GCT are rare tumors: 80% are benign, 20% malignant (2-3% of all malignant pediatric tumors. The gonadal sites (ovary and testis account for 40% of cases. Ovarian GCTs: Represent 30% of GCTs and 70% of neoplastic ovarian masses, being the most common ovarian neoplasms in children and teenagers. Benign and immature forms (teratomas constitute about 80% of all ovarian GCTs, malignant forms represent 20% increasing during adolescence. The most common malignant entity in children is the yolk sac tumors (YST; dysgerminoma is frequent during adolescence and being bilateral in 10% of cases. Presentation is similar in malignant and benign lesions; abdominal pain (70-80% and lower abdominal mass are common symptoms. Evaluation of alpha-fetoprotein (αFP or beta subunit of human chorionic gonadotropin (βHCG is essential to address the nature of the tumors: Their elevation means presence of malignancy. Surgery includes intraoperative staging procedures and requires ovariectomy or ovarosalpingectomy for malignant lesions, but may be conservative in selected benign tumors. Since malignant GCTs are very chemosensitive, primary chemotherapy is recommended in metastatic or locally advanced tumors. Testicular GCT: Represent 10% of pediatric GCT, and about 30% of malignant GCT with two age peaks: Children <3 years may experience mature teratoma and malignant GCTs, represented almost exclusively by YST, while adolescents may also show seminomas or other mixed tumors. The main clinical feature is a painless scrotal mass. Surgery represents the cornerstone of the management of testicular GCTs, with an inguinal approach and a primary high orchidectomy for malignant tumors, while a testis-sparing surgery can be considered for benign lesions. A retroperitoneal lymph node (LN biopsy may be necessary to define the staging when the involvement of retroperitoneal LN is uncertain at imaging investigations. Conclusion: Patients with gonadal

    Patients on surveillance for clinical stage I (CSI) testicular cancer are counseled regarding their baseline risk of relapse. The conditional risk of relapse (cRR), which provides prognostic information on patients who have survived for a period of time without relapse, have not been determined for CSI testicular cancer. To determine cRR in CSI testicular cancer. We reviewed 1239 patients with CSI testicular cancer managed with surveillance at a tertiary academic centre between 1980 and 2014. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: cRR estimates were calculated using the Kaplan-Meier method. We stratified patients according to validated risk factors for relapse. We used linear regression to determine cRR trends over time. At orchiectomy, the risk of relapse within 5 yr was 42.4%, 17.3%, 20.3%, and 12.2% among patients with high-risk nonseminomatous germ cell tumor (NSGCT), low-risk NSGCT, seminoma with tumor size ≥3cm, and seminoma with tumor size testicular cancer is very low. Consideration should be given to adapting surveillance protocols to individualized risk of relapse based on cRR as opposed to static protocols based on baseline factors. This strategy could reduce the intensity of follow-up for the majority of patients. Our study is the first to provide data on the future risk of relapse during surveillance for clinical stage I testicular cancer, given a patient has been without relapse for a specified period of time.

    2011-01-01

    Testicular irradiation in children suffering from acute lymphoblastic leukemia presents difficulties in relation to daily positioning, dosimetry for dose homogenization of complex geometry and volume change during irradiation thereof. This can lead to significant deviations from the prescribed doses. In addition, the usual techniques often associated with unnecessary irradiation of pelvic simphysis, anus and perineum. This, in the case of pediatric patients, is of great importance, since doses in the vicinity of 20 Gy are associated with a deviation of bone growth, low testosterone levels around 24 Gy and high rates of generation of second tumors. To overcome these problems we propose a special restraint in prone and non-coplanar irradiation.

    2015-01-01

    Clear cell sarcoma of the kidney (CCSK) accounts for 2-5% of all pediatric renal malignancies, and is known for its propensity to metastasize to bone and other sites. We are reporting two cases with bilateral CCSK that were diagnosed at our institution. One patient initially presented with bilateral renal masses, as well as pulmonary, hepatic and bone metastasis; while other present only with bilateral masses with no evident distant metastasis. Both patients received aggressive neo-adjuvant chemotherapy to decrease tumor size. One patient completed his designated treatment and initially showed complete remission (CR); eventually suffering from relapse. The other patient’s tumor progressed during the course of chemotherapy. Both cases manifested brain dissemination at the time of relapse or progression. This emphasizes the importance of staging stratification in CCSK. This also illustrates CCSK’s ability to metastasize to bone and other sites including the brain (a primary relapse site in our cases)

    2011-03-01

    Full Text Available Sarcoidosis is a multisystem disease that most commonly involves the lungs and the lymph nodes, but with genitourinary tract involvement, can easily mimic testicular cancer with metastasis to the lungs. We describe the case of a 30-year-old African-American male who presented with complaints of a headache, skin lesions, and a scrotal mass. A computed tomography scan of the head showed lesions in the frontotemporal and pons region, causing obstructive hydrocephalus. An ultrasound of the scrotum showed an enlarged epididymis bilaterally as well as a solid hypoechoic ill-defined mass on the right side, separate from the intact testis. Given the high suspicion for testicular malignancy with brain metastasis, a right orchiectomy was completed. The pathology revealed non-caseating necrotizing granulomas that stained negative for tubercular and fungal organisms, which was consistent with sarcoidosis. Additionally, the patient’s skin and central nervous system (CNS lesions improved on steroids that had been started for cerebral edema. Given the predilection of testicular cancer for CNS metastasis, neurosarcoidosis can also be mistaken for testicular cancer metastasis to the CNS, as seen in our case. Differentiating testicular cancer from genitourinary sarcoidosis is difficult but can be clarified using a combination of clinical presentation, epidemiology, serum markers (ACE, AFP, B-HCG, biopsies from skin/lymph nodes, and sometimes imaging. It is critical to differentiate genitourinary sarcoidosis from malignancy, as a misdiagnosis can lead to unnecessary surgical interventions, which have important implications for future fertility. There can also be a coexistence of as well as an association between testicular cancer and sarcoidosis, which should be recognized by health care providers. Both authors contributed equally to the manuscript.

    Testicular absence may cause psychological trauma in children. It can be avoided by placing testicular prosthesis (TP). However there is no consensus on the optimal age of implantation. We evaluate the results of TP implantation and their complications, as well as patient and family satisfaction. This is a retrospective study of TP implanted between 2004-2010 in our center. Variables analyzed are: age, size and side, indication, surgical technique, complications and comorbidity. Telephone survey was done by a single interviewer to 50 families. general family satisfaction, characteristics of the prosthesis (size, shape, location and consistency), body image and psychological situation of the child, duration of analgesia after surgery, reoperation rate, and family advice to other parents. Statistical analysis with SPSS-18.0. 107 prostheses were placed (4 bilateral, 64 left and 35 rights) at a mean age of 70,10 +/- 58,6 months. The most common indication was cryptorchidism (48.2%). Initial inguinal approach in 69%, and simultaneous contralateral orchidopexy in 29.9%. Only one patient refused the prostheses. In 71% the mother was interviewed. Parents consider size, shape and position appropriate in 55.6%, 66.7% and 82.22% respectively. Hard consistency of TP was considered in 82.3% of the patients. Psychological problems were absent in 86.7%. Nighty five percent would be willing to replace when it was necessary. Parents would recommend the intervention to parents in the same situation in 86.7%. Testicular prosthesis avoids psychological trauma. The lack of satisfaction regarding to the small size and hardness makes necessary to replace the TP in adulthood. An open question remains whether we should consider the placement of TP in early ages, or if we should establish some indications based on a more rational communication with the family.

    Full Text Available Background. The risk of ovarian cancer is increased in the association of ovarian tumor, ascites, and hydrothorax with the significant elevated tumor marker CA-125. However, this association can be observed in a rare clinical and benign pathological entity, that is Demons-Meigs’ syndrome. Objective. To describe a rare case of Demons-Meigs' syndrome observed in our department. Methods. A black African woman of 35 years old, seventh gravida and fourth parous, underwent a total abdominal hysterectomy with bilateral salpingoophorectomy for large bilateral ovarian masses associated with significant ascites, bilateral pleural effusion, and particular highly elevated tumor marker CA-125 (1835 UI/mL in a pronounced general alteration condition. Results. The postoperative course was uneventful characterized by a complete remission of hydrothorax and ascites with normal level of CA-125 three months after tumor excision. Histology of both masses revealed a bilateral ovarian fibrothecoma, a benign tumor of the ovary, thus confirming the diagnosis of Demons-Meigs’ syndrome. Conclusion. The Demons-Meigs syndrome, although it strongly mimics the clinical picture of malignant metastatic ovarian cancer, remains a disease with benign prognosis after surgical tumor resection. This is a rare condition that must be known and recognized by practitioners to avoid unnecessary practices.

  20. Hypothesis: does ochratoxin A cause testicular cancer?

    2002-02-01

    Little is known about the etiology of testicular cancer, which is the most common cancer among young men. Epidemiologic data point to a carcinogenic exposure in early life or in utero, but the nature of the exposure is unknown. We hypothesize that the mycotoxin, ochratoxin A, is a cause of testicular cancer. Ochratoxin A is a naturally occurring contaminant of cereals, pigmeat, and other foods and is a known genotoxic carcinogen in animals. The major features of the descriptive epidemiology of testicular cancer (a high incidence in northern Europe, increasing incidence over time, and associations with high socioeconomic status, and with poor semen quality) are all associated with exposure to ochratoxin A. Exposure of animals to ochratoxin A via the diet or via in utero transfer induces adducts in testicular DNA. We hypothesize that consumption of foods contaminated with ochratoxin A during pregnancy and/or childhood induces lesions in testicular DNA and that puberty promotes these lesions to testicular cancer. We tested the ochratoxin A hypothesis using ecologic data on the per-capita consumption of cereals, coffee, and pigmeat, the principal dietary sources of ochratoxin A. Incidence rates for testicular cancer in 20 countries were significantly correlated with the per-capita consumption of coffee and pigmeat (r = 0.49 and 0.54, p = 0.03 and 0.01). The ochratoxin A hypothesis offers a coherent explanation for much of the descriptive epidemiology of testicular cancer and suggests new avenues for analytic research.

    A 19-year-old man suffering from testicular choriocarcinoma presented to the dermatology department with a cutaneous metastasis on his head. This metastasis was the first sign of disease that led to medical consultation. Histopathology revealed cytotrophoblasts and syncytiotrophoblasts, the later expressing human chorionic gonadotropin antigen. Whole body computed tomography showed multiple metastases of the brain, lung, liver, bone, paraaortic lymph nodes and left uvea; the primary was found in the left testicle. Despite neurosurgical intervention and chemotherapy the patient died 9 days after the biopsy of the cutaneous metastasis. Cutaneous metastases of testicular choriocarcinoma are exceptionally rare, with fewer than a dozen cases reported in the English-language literature. The present case highlights that testicular choriocarcinoma metastatic to the skin should be included in the differential of cutaneous scalp tumors. © 2018 John Wiley & Sons A/S.

    This study aims to estimate testicular dose and the associated risks for infertility and hereditary effects from inverted-Y field irradiation Radiotherapy was simulated on a humanoid phantom using a 6 MV photon beam. Testicular dose was measured for various field sizes and tissue thicknesses along beam axis using an ionization chamber. Gonadal dose was reduced by placing lead cups around the testes supplemented by a field edge block. For a tumor dose of 40 Gy, testicular dose was 0.56-6.52 Gy depending upon the field size and the distance from the inferior field edge. The corresponding dose to shielded testes was 0.12-1.96 Gy. The increase of tissue thickness in reased the testicular dose up to 40%. An excess risk of hereditary disorders of (7-391) per 10000 births was calculated. The treatment parameters, the presence of gonad shield and the somatometric characteristics determine whether testicular dose can exceed 1 Gy which allows a complete recovery of spermatogenesis.

    2003-04-01

    We describe a new unique case of acute myeloid leukemia (AML) in a 21-yr-old male presenting with abdominal pain, bilateral testicular masses and gynecomastia. Further work-up with computed tomography of the chest, abdomen and pelvis revealed massive retroperitoneal, peripancreatic and mediastinal lymphadenopathy, suggesting primary testicular neoplasm. The patient was subjected to right orchiectomy that showed infiltration of testicular tissue with malignant cells, originally misinterpreted as undifferentiated carcinoma. Immunohistochemistry studies, however, showed these cells to be strongly positive for myeloperoxidase and CD45, indicating a myeloid cell origin. Bone marrow (BM) aspirate and biopsy demonstrated replacement of marrow with immature myeloid cells. Both the morphology and immunophenotype of the blast cells were consistent with AML type M4 (acute myelo-monocytic leukemia), using French-American-British (FAB) classification. The patient received standard induction chemotherapy with cytosine arabinoside (ARA-C) and daunorubicin followed with two cycles of consolidation therapy with high dose ARA-C, which resulted in remission of BM disease and resolution of lymphadenopathy and left testicular masses. After the second cycle of consolidation therapy, the patient developed sepsis that was complicated by refractory disseminated intravascular coagulopathy. He expired with a clinical picture of multiple organ failure. The unique features of this case are presented and the related literature is reviewed.

    Elastography of the testis can be used as a part of multiparametric examination of the scrotum. To determine the testicular stiffness using acoustic radiation force impulse imaging (ARFI) technique in men with testicular microlithiasis (TML). In 2013, 12 patients with diagnosed testicular microlithiasis in 2008 (mean age, 51 years; age range, 25–76 years) underwent a 5-year follow-up B-mode ultrasonography with three ARFI elastography measurements of each testis. We used a Siemens Acuson S3000 machine. No malignancy was found at the 5-year follow-up B-mode and elastography in 2013. However, we found an increase in TML; in the previous ultrasonography in 2008, eight men had bilateral TML, whereas in 2013, 10 men were diagnosed with bilateral TML. The mean elasticity of testicles with TML was 0.82 m/s (interquartile range [IQR], 0.72–0.88 m/s; range, 65–1.08 m/s). Elastography velocity of testis with TML seems to be in the same velocity range as in men with normal testis tissue

    Frozen section examination (FSE) for testicular masses is gaining popularity because of the possibility of performing testis-sparing surgery (TSS) on the basis of the FSE results. The aim of our study was to investigate the reliability of FSE in the diagnosis of testicular masses. From 1999 to 2016, 144 of 692 patients who underwent surgery in our tertiary center for testicular masses had FSE. The indications for FSE were: masses < 1 cm, nonpalpable, multiple, or with unusual presentation. Mean follow-up for patients was 25.5 months. The algorithm of surgery determined by FSE was: orchiectomy if malignant or nonconclusive pathology; TSS if benign or nontumor pathology. FSE data were analyzed retrospectively. Specificity and sensitivity of the method was calculated for benign, malignant, seminoma, and nonseminoma tumors. Intraoperative FSE was conducted on 21% of candidates for surgery on testicular masses. The sensitivity and specificity of FSE were 93% and 98%, respectively, for malignant tumors, and 90% and 99%, respectively, for benign tumors. The κ agreement coefficient between FSE and final histopathology was statistically significant (0.76). TSS was performed in 57 (40%) patients, including 6 of 23 monorchid patients. FSE correlates well with final histopathological diagnosis of testicular masses. Thus, it reliably identifies patients who might benefit from TSS. FSE should be considered always in small, nonpalpable, multiple, or uncommonly presenting masses in solitary testis or both testes. Copyright © 2017 Elsevier Inc. All rights reserved.

    2017-07-01

    Cochlear implants (CI) are standard for the hearing rehabilitation of severe to profound deafness. Nowadays, if bilaterally indicated, bilateral implantation is usually recommended (in accordance with German guidelines). Bilateral implantation enables better speech discrimination in quiet and in noise, and restores directional and spatial hearing. Children with bilateral CI are able to undergo hearing-based hearing and speech development. Within the scope of their individual possibilities, bilaterally implanted children develop faster than children with unilateral CI and attain, e.g., a larger vocabulary within a certain time interval. Only bilateral implantation allows "binaural hearing," with all the benefits that people with normal hearing profit from, namely: better speech discrimination in quiet and in noise, as well as directional and spatial hearing. Naturally, the developments take time. Binaural CI users benefit from the same effects as normal hearing persons: head shadow effect, squelch effect, and summation and redundancy effects. Sequential CI fitting is not necessarily disadvantageous-both simultaneously and sequentially fitted patients benefit in a similar way. For children, earliest possible fitting and shortest possible interval between the two surgeries seems to positively influence the outcome if bilateral CI are indicated.

    INTRODUCTION: Testicular cancer is the most common type of cancer in young Caucasian men. It has been suggested that testicular microlithiasis (TML) is a premalignant condition. This study's objective was to investigate TML histology prevalence in testicular cancer patients in two European...... populations. METHODS: We analysed archived histopathology orchiectomy specimens from 152 patients diagnosed with testicular cancer at Fredericia Hospital in Denmark from 2004 to 2014, and 106 patients diagnosed at St Thomas' Hospital in London from 2011 to 2015. RESULTS: The Danish patients' median age was 37...... in seminomas than in non-seminomas.
 CONCLUSIONS: The English testicular cancer patients had a statistically significantly higher TML prevalence than the Danish patients. This observation questions the hypothesised biological association between TML and testicular

    Testicular cancer is a rare malignancy, that affects 1-2 % of male population. Trends of testicular cancer mortality are stable for a long period of time, even that incidence shows a rapid growth. This paper deals with national trends in testicular cancer incidence and mortality in Slovakia from 1968 to 2007 by using the join-point regression analysis to propose potential changes in health care. The authors noted a statistically significant increase in the values of incidence and improvement in mortality after 1975. Paper also deals with the etiology and risk factors of this malignancy.

    Full Text Available Blunt scrotal injury represents a diagnostic dilemma for emergency physicians (EP. Consequently, point-of-care ultrasound (POCUS has emerged as a tool for early investigation of the acute scrotum in the emergency department. We describe a case where an EP used scrotal POCUS to immediately visualize the loss of testicular contour and underlying heterogeneous parenchyma to rapidly make the diagnosis of testicular rupture in a young male presenting with scrotal trauma. The use of POCUS in this case expedited therapy, likely improving the patient’s outcome. To our knowledge, this is the first detailed description of testicular rupture diagnosed with POCUS by an EP

    Full Text Available Introduction: Testicular benign tumors are very rare (< 5%. Testicular Angiofibroma (AF is one of those, however the gold standard of treatment and follow-up is still unclear. Case report: A 47 years-old man with only one functioning testis was referred to our clinic for a palpable right testicular mass and atrophic contralateral testis. Patient underwent testis-sparing surgery with inguinal approach and intraoperative frozen sections examination with diagnosis of AF. Final histology confirmed AF. Post-operative follow-up was uneventful. Clinical and ultrasonographic follow-up was negative after 8 months. Conclusion: We report a conservative surgery in a patient with AF of the solitary testis. AF is a benign para-testicular fibrous neoplasm that could be misinterpreted as malignant tumor and treated with orchiectomy. Testis-sparing surgery is recommended in this case with intraoperative pathological examination. The excision of the mass is enough but in front of a possible recurrence a long follow-up is advisable.

    Full Text Available The aim of this study was to evaluate the possible development of histological abnormalities such as fibrosis and microcalcifications after sperm retrieval in a ram model. Fourteen testicles in nine rams were exposed to open biopsy, multiple TESAs, or TESE, and the remaining four testicles were left unoperated on as controls. Three months after sperm retrieval, the testicles were removed, fixed, and cut into 1/2 cm thick slices and systematically put onto a glass plate exposing macroscopic abnormalities. Tissue from abnormal areas was cut into 3 μm sections and stained for histological evaluation. Pathological abnormalities were observed in testicles exposed to sperm retrieval (≥11 of 14 compared to 0 of 4 control testicles. Testicular damage was found independently of the kind of intervention used. Therefore, cryopreservation of excess sperm should be considered while retrieving sperm.

    Burkitt lymphoma, is described as an aggressive form of non-Hodgkin lymphoma of B cells which occurs most often in children and young adults, ovarian lymphoma can appear as a primary lesion or more commonly referred to as a metastasis. Primary ovarian lesions are rare manifestations corresponding to 0.5% of non-Hodgkin lymphoma and 1.5% of ovarian tumors. Clinic case: 31 years old female with general weakness, march incapacity, dyspnea, hyporexia, fever, diaphoresis, weight loss of 20 kg, flat abs with abdominal pain; Ca125 610 U/ml. Abdominal computed tomography shows a solid aspect tumor which affects the right pelvic cavity. Bilateral ovarian tumors were removed. Microscopically, both lesions show a "starry sky" pattern composed by a monotonous infiltration of lymphocytes mixed with large and clear macrophages, several atypical mitoses, and necrosis and hemorrhage areas. Immunohistochemistry was positive for CD10, CD20, and negative for CD3 and high Ki67 proliferation index. Bilateral ovarian Burkitt's lymphoma was diagnosed. Bilateral ovarian Burkitt's lymphoma is a rare entity, with a variability of presentations, the abdominal pain and abdominal tumors are the most frequent. The patient's prognosis at short term is poor, therefore it's necessary to know this entity and make an early diagnosis.

  4. EFFECT OF CANNABINOIDS ON TESTICULAR ISCHEMIA-REPERFUSION INJURY IN RAT

    Full Text Available Anandamide is an endogenous ligand for cannabinoid receptors and has endothelial protective effect against ischemic preconditioning. The purpose of this study was to investigate the effects of cannabinoids on reperfusion injury due to testicular torsion-detorsion (T/D. A total of 36 adult male Sprague-Dawley rats were divided into 6 groups. Testicular ischemia was achieved by twisting the right testes 720◦ counters clockwise for 1 hour and reperfusion was allowed for 4 hours after detorsion. In baseline (normal group, bilateral orchiectomies performed after anesthesia. Sham operated group was served as a control group. Torsion/detorsion group underwent 1 hour testicular torsion and 4 hours of detorsion. Anandamide (cannabinoid agonist group received pretreatment with intraperitoneally anandamide 30 min before torsion. AM251 (CB1 antagonist group, received intraperitoneally injection of AM251 45 min before torsion. Anandamid/AM251 (An/AM group received administrations of AM251 45 min before torsion and anandamide 30 min before torsion. The ipsilateral malondialdehyde (MDA level in T/D group were significantly higher versus control and base line groups. Ipsilateral MDA values in anandamid group were significantly lower than T/D and An/AM groups. There were also significant decreases in catalase activity in T/D group compared with control and base line groups. These values were significantly higher in cannabinoid group versus T/D and An/AM groups. Anandamide increased ipsilateral intratesticular antioxidative markers and decreased free radicals formation during reperfusion phase after unilateral testicular torsion, which was reflected in lesser testicular MDA level. Furthermore, the effects of anandamide were mediated via cannabinoid receptors, since AM251 could abolish these effects.

    Myelolipoma in the mediastinum is an extremely rare entity. In this report, we present the case of a 79-year-old asymptomatic man who had three bilateral paravertebral mediastinal tumors. The three tumors were resected simultaneously using bilateral three-port video-assisted thoracoscopic surgery (VATS). There has been no evidence of recurrence within four years after the operation. Multiple bilateral mediastinal myelolipomas are extremely rare. There are no reports in the English literature of multiple bilateral thoracic myelolipomas that were resected simultaneously using bilateral VATS. We also present characteristic features of myelolipomas, which are helpful for diagnosis. PMID:24782978

    Adult height is associated with testicular cancer risk. We studied to what extent this association is explained by parental height, childhood height and age at puberty. We conducted a case-control study on germ-cell testicular cancer patients diagnosed in 1997-2008 and resident in the Province of Turin. Information was collected using mailed questionnaires in 2008-2011. Specifically, we asked for adult height (in cm), height at age 9 and 13 (compared to peers) and age at puberty (compared to peers). We also asked for paternal and maternal height (in cm) as indicators of genetic components of adult height. The analysis included 255 cases and 459 controls. Odds ratios (ORs) of testicular cancer were estimated for the different anthropometric variables. Adult height was associated with testicular cancer risk [OR: 1.16, 95% confidence interval (CI): 1.03-1.31 per 5-cm increase]. The risk of testicular cancer was only slightly increased for being taller vs. shorter than peers at age 9 (OR: 1.55, 95% CI: 0.91-2.64) or age 13 (OR: 1.26, 95% CI: 0.78-2.01), and parental height was not associated with testicular cancer risk. The OR for adult height was 1.32 (95% CI: 1.12-1.56) after adjustment for parental height. Among participants with small average parental height (testicular cancer for tall (>180 cm) vs. short (testicular cancer is likely to be explained by environmental factors affecting growth in early life, childhood and adolescence. © 2013 UICC.

    To explore the relationship between insurance status and differences in treatment and survival of testicular cancer patients. The Surveillance, Epidemiology, and End Results (SEER) database was utilized for this study. Between 2007 and 2011, 5986 testicular cancer patients were included in the SEER database. Patients were classified into nonseminoma and seminoma groups. We compared mortality rates, metastasis (M+) at diagnosis, and rates of adjuvant treatments between the uninsured (UI) and insured (I) populations. Overall, 2.64% of UI vs 1.36% of I died from testicular cancer (P = .025) and 16.73% of UI vs 10.52% of I had M+ at diagnosis (P testicular cancer (P = .326) and 25.92% of UI vs 18.46% of I had M+ at diagnosis (P = .0007). Also 17.28% of UI vs 20.88% of I had retroperitoneal lymph node dissection (RPLND; P = .1). In the seminoma group, 1.06% of UI vs 0.33% of I died from testicular cancer (P = .030) and 7.43% of UI vs 4.81% of I had M+ at diagnosis (P = .029). Also 34.75% of UI vs 48.4% of I received adjuvant radiation (P = .0083). The lack of health insurance predicted poor survival after adjusting for tumor stage, receiving adjuvant radiation or RPLND. UI testicular cancer patients present with more advanced cancer stages and have higher mortality rates than I patients. UI seminoma patients received less adjuvant radiation. This may be related to lack of access to care or more advanced cancer stage at diagnosis. Copyright © 2016. Published by Elsevier Inc.

    Testicular cancer is thought to have a great impact on its survivors, yet there has been limited literature on the topic globally and no literature on the topic in Lebanon and the Arab region. The purpose of this study was to explore the lived experience of Lebanese testicular cancer survivors and gain an in-depth understanding of the psychosexual aspect of their experience. A hermeneutic phenomenological approach with semistructured digitally recorded interviews and observational field notes was utilized. A purposive sample of Lebanese testicular cancer survivors, aged between 18 and 50 years, in remission for at least 3 years, and willing to share personal information was recruited. Interviews were transcribed verbatim in Arabic. Data saturation was achieved at the seventh interview; a total of eight informants were recruited. The opening question was, "Tell me about your life since you got treated for testicular cancer," and was followed by probing questions. Two to three weeks after the initial interview, informants were called to validate the investigators' primary analysis. Six core themes emerged: cancer perception in the Lebanese culture; "do not show, do not tell"; cancer experience is a turning point; fertility, manhood, and relationships; coping with cancer; and preserved aspects of life. The findings provide an in-depth understanding of the experience of Lebanese testicular cancer survivors with a focus on the psychosexual aspect of this experience. The results suggest the need to educate patients about testicular cancer and its effect on their fertility.

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer

    Full Text Available Abstract Background Male breast cancer is a comparatively rare disease, and simultaneous bilateral male breast cancer is considered to be an extremely rare event. Risk factors are said to be genetic factors and hormonal abnormalities due to obesity or testicular diseases. Case presentation The patient was a 47-year-old Japanese male. His family had no history of female breast cancer. This patient also had hypospadias and hormonal examination indicated the presence of primary testicular potential hypogonadism, and these hormonal abnormalities seemed to be present since childhood or the fetal period. The bilateral breast cancer developed in this man at a comparatively young age, and histopathological studies of multiple sections showed that there was almost no normal epithelial cell in the ducts, while the ducts were almost completely filled with breast cancer cells. Conclusion It is thought that male breast cancer is caused by an imbalance between estrogen and testosterone. We cannot rule out the possibility that the breast cancer developed due to the effect of the slight elevation of estrogen over a long period of time, but the actual causative factors in this patient were unable to be definitively identified. In the future, we hope to further elucidate the causes of male breast cancer.

    Elastofibroma dorsi is a rare soft-tissue tumor of the chest wall and most commonly presents as a nontender mass adjacent to the inferior angle of the scapula. Its findings on CT and MRI generally lead to the diagnosis. We report a case of a 55-year-old woman with elastofibroma dorsi presenting with painless back mass. On sonography, it appeared as an ill-defined heterogeneous echogenic mass with internal streaky echostructures in bilateral subscapular regions. Excisional biopsy of the tumor was done and the tumor was confirmed as a bilateral elastofibroma dorsi by histopathologic examination.

    2007-01-01

    Recently a worldwide rise in the incidence of testicular germ cell cancer (TGCC) has been repeatedly reported. The changing disease pattern may signal that other testicular problems may also be increasing. We have reviewed recent research progress, in particular evidence gathered in the Nordic...... countries, which shows strong associations between testicular cancer, undescended testis, hypospadias, poor testicular development and function, and male infertility. These studies have led us to suggest the existence of a testicular dysgenesis syndrome (TDS), of which TGCC, undescended testis, hypospadias...... in TGCC rates of a population may be 'whistle blowers' of other reproductive health problems. As cancer registries are often of excellent quality - in contrast to registries for congenital abnormalities - health authorities should consider an increase in TGCC as a warning that other reproductive health...

    Excellent treatment results have been acieved historically with postoperative radiotherapy in testicular seminoma. In this retrospective study the treatment results of 211 patients with Stage I/II testicular seminoma treated in Finland during the years 1970-1983 were evaluated. 176 (84%) patients received postoperative radiotherapy alone. In addition to radiotherapy, 26 (12%) patients received chemotherapy during the primary treatment. There were 129 Stage I (61%), 66 Stage IIA-B (31%) and 16 Stage IIC (8%) tumors. The 5-year survival rate was 95% in Stage I, 87% in Stage IIA-B and 73% in Stage IIC. In Stage I, seven relapses (relapse rate 6%) occured after irradiation; three of them were cured with second-line therapies. None of the relapses occurred within the radiotherapy field. In Stage IIA-B, 31 patients had only parailiacic + aortic irradiation, 25 patients received both parailiacic + aortic and mediastinal irradiation. With both radiotherapy techniques there was no significant difference in the number of relapses (seven and three) and in the remission rate (94% and 96%). Radiotherapy alone was used on four Stage IIC patients and one of them died during the primary treatment. Two of them relapsed, but could be cured with chemotherapy. These results correspond to those reported in the literature and tye suggest that prophylactic mediastinal irradiation is unneccessary in Stage IIA-B patients. Stage IIC patients should receive chemotherapy initially. (author). 19 refs.; 2 figs.; 2 tabs

    Full Text Available Our objective was to identify predictors of improved postthaw semen quality in men with testicular cancer banking sperm for fertility preservation. We reviewed 173 individual semen samples provided by 67 men with testicular germ cell tumor (TGCT who cryopreserved sperm before gonadotoxic treatment between 1994 and 2010 at our tertiary university medical center. Our main outcomes measures were independent predictors for the greater postthaw total motile count (TMC in men with TGCT. Men with NSGCT were more likely to be younger (P median fresh TMC each had increased odds of a postthaw TMC greater than median postthaw TMC. Interestingly, age, advanced cancer stage (II or III, rapid freezing protocol, and motility enhancer did not show increased odds of improved postthaw TMC in our models. In conclusion, men with TGCT or poor fresh TMC should consider preserving additional vials (at least 15 vials before oncologic treatment. Density gradient purification should be routinely used to optimize postthaw TMC in men with TGCT. Larger, randomized studies evaluating cancer stage and various cryopreservation techniques are needed to assist in counseling men with TGCT regarding fertility preservation and optimizing cryosurvival.

    Highlights: • Functional MRI in the characterization of testicular germ cell tumors was assessed. • ADC values proved useful in the characterization of testicular germ cell tumors. • Testicular germ cell tumors had similar enhancement patterns of dynamic MRI. - Abstract: Introduction: The aim of this study is to investigate the role of apparent diffusion coefficient (ADC) values and dynamic contrast enhancement (DCE) patterns in differentiating seminomas from nonseminomatous germ cell tumors (NSGCTs). Materials and methods: The MRI examinations of the scrotum of 26 men with histologically proven testicular GCTs were reviewed. DWI was performed in all patients, using a single shot, multi-slice spin-echo planar diffusion pulse sequence and b-values of 0 and 900 s/mm 2 . Subtraction DCE-MRI was performed in 20 cases using a 3D fast-field echo sequence after gadolinium administration. Time-signal intensity curves were created and semi-quantitative parameters (peak enhancement, time to peak, wash-in and wash-out rate) were calculated. The Student's t-test was used to compare the mean values of ADC, peak enhancement, time to peak, wash-in and wash-out rate between seminomas and NSGCTs. ROC analysis was also performed. Results: Histopathology disclosed the presence of 15 seminomas and 11 NSGCTs. The mean ± s.d. of ADC values (× 10 −3 mm 2 /s) of seminomas (0.59 ± 0.009) were significantly lower than those of NSGCTs (0.90 ± 0.33) (P = 0.01). The optimal ADC cut-off value was 0.68 × 10 −3 mm 2 /s. No differences between the two groups were observed for peak enhancement (P = 0.18), time to peak (P = 0.63) wash-in rate (P = 0.32) and wash-out rate (P = 0.18). Conclusions: ADC values may be used to preoperatively differentiate seminomas from NSGCTs

    Full Text Available Mesothelioma is usually diagnosed in people over the age of 50 with large history of asbestos-related exposure. It is frequently located in pleural cavity, peritoneum, and pericardium. At the testicles the mesothelioma had been reported first in 1957 like a malignant non-germ-cells tumor. The objective is to present two case reports of benign testicular mesothelioma and review of the literature.

  2. Public awareness of testicular cancer and testicular self-examination in academic environments: a lost opportunity

    2011-01-01

    Full Text Available BACKGROUND: Although testicular cancer is the most common cancer among 18- to 50-year-old males, healthcare providers seldom teach testicular self-examination techniques to clients, thus potentially missing opportunities for early detection. This form of cancer is easily diagnosable by testicular self-examination and is 96% curable if detected early. Periodic self-examination must be performed for early detection. Knowledge deficits and sociocultural norms contribute to low levels of health-related knowledge in most patients, resulting in undue delays before seeking medical advice. OBJECTIVE: Our aim is to assess the level of awareness of testicular cancer and the prevalence of the practice of testicular self-examination in academic environments to enable appropriate interventions. METHOD: A cross-sectional survey was administered to 750 consecutive males aged 18-50 years in three tertiary institutions in Port Harcourt from October 2008 to April 2009. RESULT: Knowledge or awareness of testicular cancer was poor. Almost all of the respondents were unaware that testicular lumps may be signs of cancer. A lump was typically construed as a benign carbuncle or something that could resolve spontaneously. The main factor contributing to respondents' lack of knowledge of testicular cancer was that few reported that they were "ever taught about testicular self-examination." CONCLUSION: Young adult men are unaware of their risk for testicular cancer, which is the most common neoplasm in this age group. Healthcare providers are not informing them of this risk, nor are they teaching them the simple early detection technique of self-examination of the testes.

All complications were transient or minor. The incidence of postendarterectomy hypertension was significantly higher following...... the second procedure, when operations were staged less than 3 weeks apart. A correlation between these hypertensive episodes and the occurrence of new neurologic symptoms could not be shown. However, as this correlation has been proved in several other reports, bilateral carotid endarterectomy is advised...... to be staged at least 3 weeks apart. In addition, a conservative attitude towards contralateral asymptomatic lesions is proposed....

    Malignancies and cisplatin-based chemotherapy are both known to correlate with a high risk of venous thrombotic events (VTT). In testicular cancer, the information regarding the incidence and reason of VTT in patients undergoing cisplatin-based chemotherapy is still discussed controversially. Moreover, no risk factors for developing a VTT during cisplatin-based chemotherapy have been elucidated so far. We retrospectively analyzed 153 patients with testicular cancer undergoing cisplatin-based chemotherapy at our institution for the development of a VTT during or after chemotherapy. Clinical and pathological parameters for identifying possible risk factors for VTT were analyzed. The Khorana risk score was used to calculate the risk of VTT. Student t test was applied for calculating the statistical significance of differences between the treatment groups. Twenty-six out of 153 patients (17%) developed a VTT during chemotherapy. When we analyzed the risk factors for developing a VTT, we found that Lugano stage ≥IIc was significantly (p = 0.0006) correlated with the risk of developing a VTT during chemotherapy. On calculating the VTT risk using the Khorana risk score model, we found that only 2 out of 26 patients (7.7%) were in the high-risk Khorana group (≥3). Patients with testicular cancer with a high tumor volume have a significant risk of developing a VTT with cisplatin-based chemotherapy. The Khorana risk score is not an accurate tool for predicting VTT in testicular cancer. © 2017 S. Karger AG, Basel.

    We evaluate 311 breast cancer patients admitted to Yong Dong Severance Hospital Between October 1st 1985 and July 31th 1989, and were able to obtain the following conclusions. 1) There were 14(4.5%) bilateral breast cancers among the 311 confirmed breast cancers. 2) Among the bilateral breast cancers, 5(31%) were synchronous and 9(69%) metachronous. 3) Average interval between the first and the second breast cancer in metachronous cancers was 3.8 year(1-15 years). 4) Bilateral breast cancer was most prevalent in the fifth decade (6/14) with the mean age of 47 years. 5) Film mammogram and sonomammogram showed findings of typical breast malignancies. There was no additional specific findings for each cancer in bilateral breast cancers which was different from unilateral cancers. Therefor, in the patients with unilateral breast cancer, possibility of the second lesion in the contralateral side must be considered and a close follow up observation should be done for at least 3 years

    2009-01-01

    A 34-year-old tetraplegic patient with suppurative epididymitis was found on follow-up examination and ultrasonography to have a testicular mass. The radical orchiectomy specimen contained an undifferentiated spindled sex cord-stromal tumor arising in the rete testis. Testicular sex cord-stromal tumors are far less common than germ cell neoplasms and are usually benign. The close relationship between sex cords and ductules of the rete testis during development provides the opportunity for these uncommon tumors to arise anatomically within the rete tesis. This undifferentiated sex cord-stromal tumor, occurring in a previously unreported location, is an example of an unusual lesion mimicking an intratesticular malignant neoplasm.

    Histologic examination of a testicular biopsy sample may be required to evaluate the reproductive status of male psittacine birds. The purpose of this study was to evaluate the viability of testicular sampling from live birds by assessing the impact on the birds' health, testicular integrity, and sperm quality. Testicular biopsy samples were obtained by endoscopy 4 times during 12 months from 9 cockatiels (Nymphicus hollandicus) and 7 rose-ringed parakeets (Psittacula krameri). Only 2 of 16 birds showed testicular cicatrization or divided testicular tissue after a single endoscopy. Further complications, such as damage to the air sacs or bleeding, predominantly occurred in subsequent endoscopies. In both species, endoscopy and testicular biopsy caused only minor or transient effects on sperm production and sperm quality. These results support that a single testicular biopsy is a viable method for evaluating the reproductive status of male psittacine birds.

    Testicular cancer affects men mostly in their reproductive age with a cure rate over 90% and fertility is one of the main concerns of survivors. To further elucidate the question of fertility after treatment for testicular cancer, we performed a survey in patients treated in our institution. We sent a questionnaire to patients treated for testicular cancer at our institute from 1976 to 2002 (n = 490) of whom 297 (60.6%) responded. We considered the patients to have conserved fertility if they had children after treatment without assisted reproductive technologies. Before treatment 119/297 (40.1%) of patients and after treatment 150/297 (50.5%) of patients tried to have children (p = 0.019). Of 119 patients who tried to have children before treatment for testicular cancer 98 (82.4%) succeeded and 74/150 (49.3%) were successful after treatment (p years. The post-treatment fatherhood in patients treated with surgery only (orchidectomy +/- retroperitoneal lymphnode dissection-RPLND) was 59%, in those with additional radiotherapy 68%, and chemotherapy 50% (p = 0.233). Fertility rate in patients where a non nerve sparing RPLND was performed was only 37%, 62% in patients with nerve sapring RPLND, and 77% in patients where RPLND was not performed (p Fertility rate after treatment for testicular cancer is reduced. From our data, the most important treatment modality that influences fertility is non nerve sparing RPLND that should be avoided whenever possible in order improve the quality of life our patients.

    There are many recent observational studies on testicular microlithiasis (TM) and risk of testicular cancer. Whether TM increases the risk of testicular cancer is still inconclusive. The objective of this updated meta-analysis was to synthesize evidence from clinical observational studies that evaluated the association between TM and testicular cancer. We identified eligible studies by searching the PubMed, Embase and Cochrane Library before March 2014. Adjusted relative risks (RR) with 95% confidence interval (CI) were calculated using random-or fixed-model. A total of 14 studies involving 35,578 participants were included in the meta-analysis. On the basis of the Newcastle Ottawa Scale systematic review, eleven studies were identified as relatively high-quality. TM was strong association with an increased incidence of testicular cancer (RR = 12.70, 95% CI: 8.18-19.71, P testicular cancer. More researches are warranted to clarify an understanding of the association between TM and risk of testicular cancer.

  19. Intravaginal testicular torsion in newborns. To fix or not to fix the contralateral testis?

    Directory of Open Access Journals (Sweden)

    G. Bordin

    2013-10-01

    Full Text Available Scrotal swelling suggesting testicular torsion is a rare urological emergency which requires a clinical urgent evaluation and most of the times must be managed surgically. In newborns it can occur in the postnatal period, usually within the twenty-eighth day of life, or more frequently in utero, during the descent of the testis into the scrotum. Usually its poor fixedness allows the testis an abnormal mobility inside the scrotum, configuring the framework of extravaginal torsion. On the contrary during the perinatal period a twist that takes place inside the tunica vaginalis, known as intravaginal torsion, is extremely uncommon and only few cases are well documented in the literature. Authors present a rare case of intravaginal testicular torsion occurred in perinatal period. In this situation only the early surgical exploration of the scrotum may allow the rescue of the gonad, although in rare cases. Timing of surgical treatment and need for contralateral testicular fixation remain controversial. However since the anatomical defect of the tunica vaginalis can be bilateral the surgical fixation even of the contralateral testis is important, now or later, in order to prevent any future torsion of this gonad. The authors also present a brief review of recent literature on the subject.

    Testicular germ cell tumor (TGCT) is one of the most heritable forms of cancer. In last years, many evidence suggested that constitutional genetic factors, mainly single nucleotide polymorphisms, can increase its risk. However, the possible contribution of copy number variations (CNVs) in TGCT susceptibility has not been substantially addressed. Indeed, an increasing number of studies have focused on the effect of CNVs on gene expression and on the role of these structural genetic variations as risk factors for different forms of cancer. E2F1 is a transcription factor that plays an important role in regulating cell growth, differentiation, apoptosis and response to DNA damage. Therefore, deficiency or overexpression of this protein might significantly influence fundamental biological processes involved in cancer development and progression, including TGCT. We analyzed E2F1 CNVs in 261 cases with TGCT and 165 controls. We found no CNVs in controls, but 17/261 (6.5%) cases showed duplications in E2F1 Blot analysis demonstrated higher E2F1 expression in testicular samples of TGCT cases with three copies of the gene. Furthermore, we observed higher phosphorylation of Akt and mTOR in samples with E2F1 duplication. Interestingly, normal, non-tumoral testicular tissue in patient with E2F1 duplication showed lower expression of E2F1 and lower AKT/mTOR phosphorylation with respect to adjacent tumor tissue. Furthermore, increased expression of E2F1 obtained in vitro in NTERA-2 testicular cell line induced increased AKT/mTOR phosphorylation. This study suggests for the first time an involvement of E2F1 CNVs in TGCT susceptibility and supports previous preliminary data on the importance of AKT/mTOR signaling pathway in this cancer. © 2017 Society for Endocrinology.

    To determine the efficacy of ultrasound in boys presenting torsion of a testicular appendage. A series of 30 boys with acute scrotal pain due to torsion of a testicular appendage was studied. Nine patients underwent surgery. The clinical findings and course in the remaining 21 suggested the presence of this abnormality. All of them underwent conventional and color Doppler ultrasound using a 7.5 MHz transducer. In 15 boys, ultrasound images depicted the affected appendage as a mass between the epididymal head and the testicle. In 13 cases, only signs of a inflammatory reaction, with enlargement of the epididymal head and tunicas presenting hyperflow and hydrocele, mimicking acute epididymities. In two cases, the images were normal. There is no definitive, distinguishing ultrasound image corresponding to testicular appendage torsion. Therefore, this diagnostic technique should be accompanied by clinical assessment. (Author) 14 refs

    between the BCT, UCT, and BMAST groups with respect to age, histology, clinical stage, primary tumor size, axillary nodal status, or adjuvant systemic therapy. As noted below, there were no statistically significant differences between the three study groups with respect to overall survival, disease-free survival, distant metastasis-free survival, or local regional relapse-free survival. It is noteworthy that there was no significant difference between the local breast relapse rate and the chest wall relapse rate when comparing the conservatively treated group and the bilateral mastectomy group. Conclusions: Patients with bilateral breast carcinoma presenting either synchronously or metachronously are suitable candidates for bilateral conservative treatment. Outcome of these patients with respect to all measurable endpoints did not significantly differ from patients treated conservatively for unilateral breast cancer, or for their counterparts with bilateral disease of similar stage treated with bilateral mastectomy. Of particular note, the 10-year local regional relapse-free rate of patients undergoing bilateral mastectomy did not differ significantly from the local regional relapse rate of those patients treated with bilateral conservative treatment

    Full Text Available Testicular cancer is the most common malignancy of men aged 15–40. Metastatic spread classically begins with involvement of the retroperitoneal lymph nodes, with metastases to the liver, lung, bone, and brain representing advancing disease. Treatment is based on pathologic analysis of the excised testicle and presence of elevated tumor markers. We report a case of a 34-year-old male presenting with back pain who was found to have a right renal mass with tumor extension into the inferior vena cava. Subsequent biopsy was consistent with seminoma. We review this rare case and discuss the literature regarding its diagnosis and management.

    2008-01-01

    Fertility among human beings appear to be on the decline in many Western countries, and part of the explanation may be decreasing male fecundity. A hypothesis has been put forward that decreasing semen quality may be associated with a testicular dysgenesis syndrome (TDS), a spectrum of disorders...... originating in early foetal life. TDS comprises various aspects of impaired gonadal development and function, including testicular cancer. A growing body of evidence, including animal models and research in human beings, points to lifestyle factors and endocrine disrupters as risk factors for TDS. We present...

    2007-03-01

    Recent epidemiological evidence demonstrates that boys born to women exposed to phthalates during pregnancy have an increased incidence of cryptorchidism, hypospadias, testicular cancer and spermatogenic dysfunction, which are collectively referred to as testicular dysgenesis syndrome (TDS). TDS may be attributed to the dysfunction of Leydig cells and Sertoli cells during their differentiation after exposure to phthalates in utero. Fox example, Leydig cell functions are significantly affected by phthalates, leading to the decrease of two Leydig cell products--insulin-like growth factor 3 (INSL3) and testosterone, which are critical factors for testis descent. The disorientation of Leydig cells and Sertoli cells in the adult testis may be the cause of spermatogenic dysfunction.

    Bilateral renal calculi were present in 114 (10.7%) of 1,070 cases of proved urinary calculus admitted to the Urological Department of the General Hospital, Kuala Lumpur, during the period November 1968—May 1973. The management of bilateral renal calculi is discussed with reference to the first 100 cases in this series. The introduction of renography has greatly facilitated the decision as to which kidney should be operated on first. The management of patients with and without uraemia is discussed and the use of the modified V and V—Y incisions for the removal of staghorn calculi is described. Complications and results are briefly reviewed. ImagesFig. 1Fig. 4Fig. 6Fig. 7 PMID:4845653

    OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors...... are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012...... that a separated hematoma density and the absence of postoperative drainage were independent predictors of retreatment. CONCLUSIONS In bCSDHs bilateral surgical intervention significantly lowers the risk of retreatment compared with unilateral intervention and should be considered when choosing a surgical...

    Finland has made both multilateral and bilateral agreements on the exchange of information related to radiation safety. The first arrangements for international agreements and exchange of information were made after the Chernobyl accident. In 1987, Finland joined the convention on early notification of a nuclear power accident coordinated by International Atomic Energy Agency. The convention is applied to accidents that cause of may cause emissions of radioactive substances that might affect the radiation safety of another country. Besides the convention on early notification, some other individual agreements have also been made. These include the International Nuclear Event Scale (INES) system and power companies own information exchange systems. Finland has conducted bilateral agreements with the Nordic countries and the Soviet Union on the notification of accidents and exchange of nuclear power plant information. Today, Russia answers for the Soviet Union's contractual obligations. (orig.)

    Current methods of administering busulfan to remove the endogenous germ cells cause hematopoietic toxicity, require special instruments and a narrow transplantation time. We use a direct testicular injection of busulfan method for preparing recipients for SSC transplantation. Male ICR mice (recipients) were divided into four groups, and two experimental groups were treated with a bilateral testicular injection of 4 or 6 mg/kg/side busulfan (n = 60 per concentration group). Mice received an intraperitoneal injection (i.p.) of 40 mg/kg busulfan (n = 60, positive control) and bilateral testicular injections of 50% DMSO (n = 60, negative control). Donor SSCs from RFP-transgenic C57BL/6J mice were introduced into the seminiferous tubules of each recipient testis via efferent duct injection on day 16-17 after busulfan treatment. Recipient mice mated with mature female ICR mice and the number of progeny was recorded. The index detected at day 14, 21, 28, 35 and 70 after busulfan treatment. Blood analysis shows that the toxicity of busulfan treated groups was much lower than i.p. injection groups. Fertility was restored in mice treated with busulfan and donor-derived offspring were obtained after SSC transplantation. Our study indicated that intratesticular injection busulfan for the preparation of recipients in mice is safe and feasible.

    2012-02-01

    Acute testicular ischemia caused by an incarcerated inguinal hernia usually affects infants. There are few reports of diagnosis using US, and the effect of long-standing reducible hernias on testicular growth in infants and children is unknown. The objectives of this study were to determine the incidence of testicular ischemia secondary to an incarcerated inguinal hernia at scrotal sonography and to determine the effect on testicular size at diagnosis. A hospital database was used to locate scrotal sonography examinations documenting an inguinal hernia, and images were reviewed for signs of testicular ischemia. Testicular volumes were compared using the Wilcoxon signed rank test. A total of 147 patients were identified with an inguinal hernia (age 1 day to 23 years, average 6 years). Ten patients (6.8%) had associated testicular ischemia (age 3 weeks to 6 months, average 9 weeks) and showed a statistically significant increase in ipsilateral testicular size compared to the contralateral testicle (P = 0.012). Patients without testicular ischemia did not show a significant difference in testicular size, regardless of patient age. An incarcerated inguinal hernia should be considered as a cause of acute testicular ischemia in infants younger than 6 months of age.

    2014-07-01

    Juvenile nasopharyngeal angiofibroma (JNA) is the most common benign neoplasm of the nasopharynx. Almost always unilateral on diagnosis, JNAs are locally invasive and may extend across the midline, giving a false bilateral appearance; as such, true bilateral JNA is exceedingly rare. We present a recent case of true bilateral JNA. Single case report of a patient with bilateral JNA, including clinical presentation, diagnosis, and management. The patient presented with unilateral nasal obstruction and recurrent epistaxis. Computed tomography and magnetic resonance imaging demonstrated bilateral, noncontiguous masses. Angiography revealed independent vascular supplies from each respective side with no bilateral supply noted. The patient underwent preoperative embolization followed by endoscopic surgical removal of the larger mass; no complications were noted. Follow-up at 2 years demonstrated no recurrence or growth. The vast majority of JNAs are unilateral, though invasive growth to the contralateral side may appear "bilateral" in presentation. Proper identification of true bilateral JNA is helpful in guiding management, wherein excision of both tumors may not be necessary. © 2014 ARS-AAOA, LLC.

    Full Text Available Primary testicular diffuse large-B cell lymphoma (DLBCL is an uncommon and aggressive disease with predominant manifestation in the older age. Herein, we report a case of 47-year-old male patient who presented with three months history of left testis swelling. The patient underwent unilateral (left radical orchiectomy. Histopathological examination revealed extensive involvement and replacement of testicular parenchyma by a tumor composed of large discohesive sheets of cells with pleomorphic, hyperchromatic nuclei and prominent nucleoli. Immunohistochemical (IHC staining showed reactivity for LCA & Pan B (CD20 and negativity for OCT 3/4, SALL4 and Inhibin. Moreover, Pan T (CD3 highlighted reactive T-cells. These features rendered the diagnosis of DLBCL of testis. The hybrid 2-[fluorine-18] fluoro-2-deoxy-d-glucose (FDG positron emission tomography/computed tomography (PET/CT demonstrated two para-aortic FDG avid lymph nodes on the left side at the level of L2 vertebra. Presently, the patient has been planned for doxorubicin-based chemotherapy (i.e., cyclophosphamide, doxorubicin, vincristine and prednisone; CHOP along with intrathecal Methroxate (MTX, which would presumably improve the prognosis. Our study would expand the pool of this uncommon tumor towards its better understanding.

    Testicular prosthesis placement is a useful important adjunctive reconstructive therapy for managing children with testicular loss or absence. Though these prostheses are functionless, experience has shown that they are extremely helpful in creating a more normal male body image and in preventing/relieving psychological stress in males with a missing testicle. With attention to details of implant technique, excellent cosmetic results can be anticipated in simulating a normal appearing scrotum. PMID:26816795

    This report describes a rare case of recurrent bilateral focal myositis and its successful treatment via methotrexate. A 38-year-old man presented myalgia of the right gastrocnemius in May 2005. Magnetic resonance imaging showed very high signal intensity in the right gastrocnemius on short-tau inversion recovery images. A muscle biopsy revealed inflammatory CD4+ cell-dominant myogenic change. Focal myositis was diagnosed. The first steroid treatment was effective. Tapering of prednisolone, however, repeatedly induced myositis relapse, which progressed to multiple muscle lesions of both lower limbs. Initiation of methotrexate finally allowed successful tapering of prednisolone, with no relapse in the past 4 years.

    Full Text Available Cystic trophoblastic tumor (CTT is a rare testicular germ cell tumor (GCT predominantly seen in post-chemotherapy patients. It is prognostically similar to teratoma and requires no additional chemotherapy in the absence of a nonteratomatous GCT component. We report a case of metastatic CTT in a patient with primary testicular teratoma without prior chemotherapy. Retroperitoneal lymph node metastases contained teratoma, embryonal carcinoma, and CTT. The CTT was β-hCG positive and SALL4 negative by immunohistochemistry (IHC. CTT can arise in metastatic testicular GCT in treatment naïve patients. An important differential diagnosis is choriocarcinoma due to treatment implications, and SALL4 IHC may help.

    This article reviews 12 patients with bilateral acoustic neuromas. The sex incidence was equal and the mean age at diagnosis was 26.2 years. The family history was positive in nine of the patients. Five patients have had incomplete surgical removal of acoustic neuromas on both sides. Two of them are completely deaf and the other three have severe sensorineural hearing loss in one ear and no hearing in the other ear. In five patients the tumour on one side has been operated on and the other side is being observed with at least short-term preservation of good hearing. The remaining two patients died of intra-cranial complications, one of them post-operatively. Four patients developed facial palsy immediately following surgery and one developed facial weakness 6 months after surgery. Guidelines are discussed for the care of these patients including the timing of surgery and alternative treatment options (observation, radio-surgery and chemotherapy). This is essentially a group of young individuals who have had multiple operations for bilateral acoustic tumours and associated manifestations and for whom the disease and the sequelae of treatment can be tragic.

    Chemotherapy has afforded a high percentage of definitive cures in advanced testicular cancer. Nevertheless some patients with large tumor burden still succumb to chemorefractory disease. Therefore preclinical and clinical evaluation of new drugs and agents not primarily used against this type of disease are still mandatory. For preclinical drug screening purposes heterotransplantation of specific human tumors yields a model with high validity for tumor markers and drug response. Heterotransplantation of a human embryonal testicular cancer was used for simultaneous testing of established agents such as cisplatin, melphalan, bleomycin, vinblastine, etoposide and adriamycin and some newer derivatives such as PHM or mafosfamide. Furthermore agents such as procarbazine, dacarbazine and methyl-CCNU that cross the blood-brain-barrier displayed some interesting activity. The results hint at a unique chemosensitivity pattern of the xenograft line, with some accordance between clinical response to vinblastine and bleomycin and good response of the xenografts to bleomycin but not to vinblastine. Radiotherapy was also effective against this tumor line, but there was not much difference in response when the schedule of fractionation was changed. It is concluded that a combined modality approach might salvage patients with residual, chemorefractory disease. (orig.) [de

    The purpose of this study was to evaluate the differential diagnostic value of 18 F-fluorodeoxy glucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT) for benign and malignant testicular lesions. The PET/CT scans of 53 patients with testicular lesions confirmed by biopsy or surgical pathology were retrospectively analyzed. There were 32 cases of malignant tumors and 21 cases of benign lesions. Differences in the maximum standardized uptake value (SUVmax) measurements and the SUVmax lesion/background ratios between benign and malignant lesions were analyzed. The diagnostic value of this PET/CT modality for the differential diagnosis of benign versus malignant testicular lesions was calculated. The differences in the SUVmax measurements and the SUVmax lesion/background ratios between benign and malignant lesions were statistically significant (SUVmax: Z=-4.295, p=0.000; SUVmax lesion/background ratio: Z=-5.219, p=0.000); specifically, both of these indicators were higher in malignant lesions compared to benign lesions. An SUVmax of 3.75 was the optimal cutoff value to differentiate between benign and malignant testicular lesions. The diagnostic sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of this PET/CT modality in the differential diagnosis of benign versus malignant testicular lesions were 90.6%, 80.9%, 86.8%, 87.9%, and 85.0%, respectively. 18 F-FDG PET/CT can accurately identify benign and malignant testicular lesions.

E-mail wm.vale@hotmail.com This article aimed to discuss the changes in the testicular parenchyma, analyzed by the use of ultrasonography, and correlates them with the testicular biometric parameters and testosterone concentration in crossed Murrah x Mediterranean buffaloes. Nineteen buffaloes, with initial ages between 11 and 59 months,were submitted to fortnightly collections of semen for a period of six months. At each collection the testicular biometry and testicular echogenicity were evaluated as well as blood samples were also collected to measure the plasma testosterone levels. The data were submitted to analysis of variance by the GLM procedure, considering the age group fixed effect. The average data obtained were compared by the Duncan test, at 5% significance. There was a significant growth (P<0.05 of the scrotal circumference, which varied from 12.88±0.51 cmto 31.18±0.75 cm among animals aged 12 to 60 months, as well as testicular volume, which ranged from 30.28±17.37 to 611.96±38.69 cm³ among the animals.

    Full Text Available Breast tuberculosis is a rare form of tuberculosis. Moreover the disease is often overlooked and misdiagnosed as carcinoma or pyogenic abscess. Reports on breast tuberculosis from India have been few; reported incidence of breast tuberculosis amongst the total number of mammary conditions varies between 0.64 and 3.59 per cent. Bilateral involvement is still more uncommon (3%. Most accepted view for spread of infection is centripetal lymphatic spread as axillary node involvement was shown to occur in 50 to 75 per cent of cases of tubercular mastitis. Here we re-port a case of a young female who presented with draining sinuses in the breast and no axillary lymphadenopathy. Fine needle aspiration cytology (FNAC of breast lump showed evidence of granulomatous mastitis. She was given therapeutic trial of four drug antitubercular treatment. Both the lump disappeared and sinus healed after six months of antitubercular treatment. Thus a retrospective diagnosis of tu-bercular mastitis was made.

    Knowledge of the variations of the renal artery has grown in importance with increasing numbers of renal transplants, vascular reconstructions and various surgical and radio logic techniques being performed in recent years. We report the presence of bilateral triple renal arteries, discovered on routine dissection of a male cadaver. On the right side, one additional renal artery originated from the abdominal aorta (distributed to superior pole of the kidney) and one other originated from the right common iliac artery (distributed to lower pole of the kidney). On the left side, both additional renal arteries originated from the abdominal aorta. Our observation has been compared with variations described in the literature and their clinical importance has been emphasized. (author)

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    Over 300 cases of femoral neck fractures following radiotherapy for intrapelvic malignant tumor have been reported in various countries since Baensch reported this disease in 1927. In Japan, 40 cases or so have been reported, and cases of bilateral femoral neck fractures have not reached to ten cases. The authors experienced a case of 75 year-old female who received radiotherapy for cancer of the uterus, and suffered from right femoral neck fracture 3 months after and left femoral neck fracture one year and half after. As clinical symptoms, she had not previous history of trauma in bilateral femurs, but she complained of a pain in a hip joint and of gait disturbance. The pain in left femoral neck continued for about one month before fracture was recognized with roentgenogram. As histopathological findings, increase of fat marrow, decrease of bone trabeculae, and its marked degeneration were recognized. Proliferation of some blood vessels was found out, but thickness of the internal membrane and thrombogenesis were not recognized. Treatment should be performed according to degree of displacement of fractures. In this case, artificial joint replacement surgery was performed to the side of fracture of this time, because this case was bilateral femoral neck fractures and the patient had received artificial head replacement surgery in the other side of fracture formerly.

    Introduction. DSM-5 identifies two disorders: somatic symptom disorder and illness anxiety disorder, to replace hypochondriasis in DSM-IV. Patients with both disorders are intensely anxious about the possibility of an undiagnosed illness or devote excessive time and energy to health concerns and are not easily reassured. Both disorders cause considerable distress and life disruption, even at moderate levels. However, hypochondriasis (DSM-IV) is an indication for neither orchidopexy nor orchidectomy. This is the rationale for this report which is the first of its kind to the best of available literature. This is an original case report of interest to a particular clinical specialty of mental health but it will have a broader clinical impact across medicine. Case Presentation. A 30-year-old black male presented to a primary care clinic with multiple internet searches on the topic of testicular pain and its differential diagnosis. He had a bilateral orchidopexy for a suspected torsion. He was referred to mental health unit, to determine fitness for further surgery. Conclusions. If hypochondriasis is suspected in a medical or surgical inpatient, a psychological medicine consultation should be performed, to elucidate the diagnosis, to avoid unnecessary procedures, and to optimize patient's care.

    Full Text Available The case of a female who had severe, rare, terminal breast mucinous carcinoma (BMC and failed to receive surgery and chemotherapy was reported. The patient was diagnosed with pure BMC (ER++, PR++, CerbB-2−, and Ki-67 10% accompanied with bilateral lungs, bilateral chest walls with skin ulcer (D = 14 cm, lymph nodes of bilateral armpits, and right supraclavicular metastases. ECOG (Eastern Cooperative Oncology Group and NRS (Numeric Rating Scale pain scores were 4 and 6, respectively. Because the patient refused traditional chemotherapy and radiotherapy on religious grounds, an herbal medicine containing Panax ginseng, Agrimonia pilosa, and white flower Patrinia herb was administered; extensive nursing for tumor debridement was also provided. Quality of Life (QOL improved and pain reduced. Tumor-bearing survival time was prolonged. The present case dictates that herbal extract medicines and supportive treatment can be helpful for uncommon severe BMC as an appropriate alternative treatment.

    Full Text Available Brucellosis is a zoonosis caused by Brucella species. Brucella epididymo-orchitis had been reported in up to 20% of patients with brucellosis. This case was a male patient who developed Brucella epidiymo-orchitis and testicular abscess. He had fever, arthralgia and his right epididymis and right testicle were enlarged and tender. Ultrasound evaluation showed hypertrophy of the right epididymis and testis and moreover hypoechoic area within the testis. Brucella serology was positive and the patient did not respond completely to treatment with streptomycin, doxycycline, and rifampicina. Unilateral orchidectomy was decided. In areas where brucella infection is endemic brucella epididymo-orchitis should be considered in the differential diagnosis. Effective and rapid treatment is important. It should be noted that these patients may develop testicular abscess.

    2014-08-01

    Full Text Available The present study aimed to evaluate if there are differences in testicular parenchyma echogenicity between pre-pubescent and pubescent animals at the same age. Ultrasound examinations were performed in longitudinal and transversal planes of the testicles of 111 healthy Nelore bovines, at the ages of nine, 13 and 15 months. The EIV software calculated the echogenicity of the testicular parenchyma, which ranged from 0 (anechoic to 100% (hyperechoic. Animals that had reached puberty at 15 months of age presented higher testicular echogenicity than the animals that had not reached puberty at the same age. These results suggest that testicular ultrasonography can be used as a predictor of sexual precocity.

    Testicular cancer is diagnosed at a young age and survival rates are high; thus, the long-term effects of cancer treatment need to be assessed. Our objectives are to estimate the incidence rates and determinants of late effects in testicular cancer survivors. We conducted a population-based cohort study of testicular cancer survivors, diagnosed 1991-2007, followed up for a median of 10 years. We identified 785 testicular cancer patients who survived ≥5 years and 3323 men free of cancer for the comparison group. Multivariate Cox regression analysis was used to compare the hazard ratio between the cases and the comparison group and for internal analysis among case patients. Testicular cancer survivors experienced a 24 % increase in risk of long-term health effects >5 years after diagnosis. The overall incidence rate of late effects among testicular cancer survivors was 66.3 per 1000 person years. Higher risks were observed among testicular cancer survivors for hypercholesterolemia, infertility, and orchitis. Chemotherapy and retroperitoneal lymph node dissection appeared to increase the risk of late effects. Being obese prior to cancer diagnosis appeared to be the strongest factor associated with late effects. Testicular cancer survivors were more likely to develop chronic health conditions when compared to cancer-free men. While the late effects risk was increased among testicular cancer survivors, the incidence rates of late effects after cancer diagnosis was fairly low.

  10. Candidate Genes for Testicular Cancer Evaluated by In Situ Protein Expression Analyses on Tissue Microarrays

    2003-09-01

    Full Text Available By the use of high-throughput molecular technologies, the number of genes and proteins potentially relevant to testicular germ cell tumor (TGCT and other diseases will increase rapidly. In a recent transcriptional profiling, we demonstrated the overexpression of GRB7 and JUP in TGCTs, confirmed the reported overexpression of CCND2. We also have recent evidences for frequent genetic alterations of FHIT and epigenetic alterations of MGMT. To evaluate whether the expression of these genes is related to any clinicopathological variables, we constructed a tissue microarray with 510 testicular tissue cores from 279 patients diagnosed with TGCT, covering various histological subgroups and clinical stages. By immunohistochemistry, we found that JUP, GRB7, CCND2 proteins were rarely present in normal testis, but frequently expressed at high levels in TGCT. Additionally, all premalignant intratubular germ cell neoplasias were JUP-immunopositive. MGMT and FHIT were expressed by normal testicular tissues, but at significantly lower frequencies in TGCT. Except for CCND2, the expressions of all markers were significantly associated with various TGCT subtypes. In summary, we have developed a high-throughput tool for the evaluation of TGCT markers, utilized this to validate five candidate genes whose protein expressions were indeed deregulated in TGCT.

    Full Text Available Aims. In this study we report our results with storage of cryopreserved semen intended for preservation and subsequent infertility treatment in men with testicular cancer during the last 18 years. Methods. Cryopreserved semen of 523 men with testicular cancer was collected between October 1995 and the end of December 2012. Semen of 34 men (6.5% was used for fertilization of their partners. They underwent 57 treatment cycles with cryopreserved, fresh, and/or donor sperm. Results. A total of 557 men have decided to freeze their semen before cancer treatment. Azoospermia was diagnosed in 34 men (6.1%, and semen was cryopreserved in 532 patients. Seminoma was diagnosed in 283 men (54.1% and nonseminomatous germ cell tumors in 240 men (45.9%. 34 patients who returned for infertility treatment underwent 46 treatment cycles with cryopreserved sperm. Totally 16 pregnancies were achieved, that is, 34.8% pregnancy rate. Conclusion. The testicular cancer survivors have a good chance of fathering a child by using sperm cryopreserved prior to the oncology treatment, even when it contains only limited number of spermatozoa.

    Treatment guidelines for early-stage testicular cancer have increasingly recommended de-escalation of therapy with surveillance strategies. This study was designed to describe temporal trends in routine clinical practice and to determine whether de-escalation of therapy is associated with inferior survival in the general population. The Ontario Cancer Registry was linked to electronic records of treatment to identify all patients diagnosed with testicular cancer treated with orchiectomy in Ontario during 2000-2010. Treatment after orchiectomy was classified as radiotherapy (RT), retroperitoneal lymph node dissection (RPLND), chemotherapy, or none. Surveillance was defined as no identified treatment within 90 days of orchiectomy. Overall survival (OS) and cancer-specific survival (CSS) were measured from the date of orchiectomy. The study population included 1564 and 1086 cases of seminomas and nonseminoma germ cell tumors (NSGCTs), respectively. Among patients with seminomas, there was a significant increase in the proportion of patients with no treatment within 90 days of orchiectomy (from 56% to 84%; P testicular cancer in routine practice since 2000. Long-term survival in routine practice is excellent and has not decreased with the uptake of surveillance strategies. Cancer 2018. © 2018 American Cancer Society. © 2018 American Cancer Society.

    Full Text Available Heritable mutations may result in a variety of adverse outcomes including genetic disease in the offspring. In recent years the focus on germ cell mutagenicity has increased and the “Globally Harmonized System of Classification and Labelling of Chemicals (GHS” has published classification criteria for germ cell mutagens (Speit et al., 2009. The in vivo Comet assay is considered a useful tool for investigating germ cell genotoxicity. In the present study DNA strand breaks in testicular cells of mice were investigated. Different classes of chemicals were tested in order to evaluate the sensitivity of the comet assay in testicular cells. The chemicals included environmentally relevant substances such as Bisphenol A, PFOS and Tetrabrombisphenol A. Statistical power calculations will be presented to aid in the design of future Comet assay studies on testicular cells. Power curves were provided with different fold changes in % tail DNA, different number of cells scored and different number of gels (Hansen et al., 2014. An example is shown in Figure 1. A high throughput version of the Comet assay was used. Samples were scored with a fully automatic comet assay scoring system that provided faster scoring of randomly selected cells.

    Full Text Available The objective of this study was to evaluate the quantitative histology and testicular biometrics in zebu bulls of different breeds. Testicular fragments of Nelore (n=10, Polled Nelore (n=6, Gir (n=5, Guzerat (n=5 and Tabapuã bulls (n=5 were used. The fragments were perfusion-fixed in Karnovsky solution, embedded in glycol methacrylate and stained with toluidine blue-1% sodium borate. The Nelore animals had a higher tubular volumetric proportion (85.2% and greater height of the seminiferous epithelium (73.2 µm than the Gir, Guzerat and Tabapuã breeds. The Nelore animals also had a higher volumetric proportion of Leydig cells (5.2% than the Guzerat and Tabapuã breeds. There was no significant difference for any of these parameters between the Nelore and Polled Nelore breeds. The gonadosomatic index, seminiferous tubule diameter, cross-sectional area of the seminiferous tubule and tubule length (total length and length per gram of testicular parenchyma did not vary among the breeds studied. The morphometric parameters evaluated suggested that the genetic selection applied to the Nelore and Polled Nelore breeds improved the efficiency of spermatogenesis in these breeders.

    To derive a practical procedure to store canine somatic cells, fibroblasts isolated from testicular or ovarian tissues were cryopreserved in 1.2 M ethylene glycol or in 1.2 M dimethylsulfoxide prepared in Dulbecco's Modified Eagle Medium as cryoprotectants, and were frozen either in plastic straws or vials. Thawed cells were cultured for 24 hr at 38.5 degree C in a humidified atmosphere of 5 percent CO2 95 percent air, and then their membrane integrity was assayed with a double fluorescent stain, Fertilight. In addition, frozen-thawed fibroblasts were cultured for 4 days, and then their functional survival was measured after staining small colonies with trypan blue. After freezing and thawing, membrane integrity of testicular fibroblasts was 55-70 percent and functional survival ranged from 20-40 percent. With frozen-thawed ovarian cells, the average membrane integrity was 55-75 percent and the average functional survival was 35-40 percent. When frozen in ethylene glycol, functional survival of ovarian fibroblasts was significantly higher than that of testicular cells (P less than 0.05). These methods should prove useful to preserve cells collected from canids in the wild.

    Testicular cancer (TC) is a rare form of cancer, accounting for 1% of all new cancer cases in Canadian males. TC is the most common malignancy among young men, aged 25-34 yr old. Over previous decades, the incidence of TC has increased in many Western countries. Countries with a sufficiently long period of cancer registration, such as Denmark, document this trend back to the first half of the 20th century. The etiology of TC remains poorly understood. Most of the established risk factors are likely related to in utero events, including some factors that are purported to be surrogate measures for exposure to endogenous estrogens. The correlation of TC with other testicular abnormalities and with pregnancy factors led to the proposal that these conditions are a constellation of sequelae of impairment of testicular development called testis dysgenesis syndrome. There is some limited evidence suggesting that exposure to pharmacological estrogens may contribute to some cases of TC. There is currently no compelling evidence that exposure to environmental estrogenic or other hormonally active substances is contributing to the rise in TC incidence observed in Western nations over the last several decades; however, this question has not been extensively studied. The (1) rarity of this condition in the population, (2) long lag time between the presumed sensitive period during fetal development and clinical appearance of the condition, and (3) lack of a good animal model to study the progression of the disease have greatly hindered the understanding of environmental influences on TC risk.

    Background Testicular cancer (TC) is one of the most curable cancers. Given survival rates of close to 100% with appropriate therapy, ensuring proper treatment is essential. We reviewed and summarized the literature on the association of socioeconomic position (SEP) along the cancer control spectrum from risk factors to survivorship. Methods We searched PubMed from 1966 to 2011 using the following terms: testicular cancer, testicular neoplasm, poverty, and socioeconomic factors, retrieving 119 papers. After excluding papers for the non-English (10) language and non-relevance (46), we reviewed 63 papers. We abstracted information on socioeconomic position (SEP), including occupation, education, income, and combinations of the 3. Five areas were examined: risk factors, diagnosis, treatment, survival, and survivorship. Results Most studies examined area-based measures, not individual measures of SEP. The majority of studies found an increased risk of developing TC with high SEP though recent papers have indicated increased risk in low-income populations. Regarding diagnosis, recent papers have indicated that lower levels of education and SEP are risk factors for later-stage TC diagnosis and hence higher TC mortality. For treatment, 1 study that examined the use of radiation therapy (RT) in stage I seminoma reported that living in a county with lower educational attainment led to lower use of RT. For survival (mortality), several studies found that men living in lower SEP geographic areas experience lower survival and higher mortality. Conclusion The strongest evidence for SEP impact on testicular germ cell tumor (TGCT) was found for the risk of developing cancer as well as survival. The association of SEP with TGCT risk appears to have changed over the last decade. Given the highly curable nature of TGCT, more research is needed to understand how SEP impacts diagnosis and treatment for TGCT and to design interventions to address disparities in TGCT outcomes and SEP

    Exposure to radiation during fetal development induces testicular germ cell tumors (TGCT) and reduces spermatogenesis in mice. However, whether DNA damaging chemotherapeutic agents elicit these effects in mice remains unclear. Among such agents, cyclophosphamide (CP) is currently used to treat breast cancer in pregnant women, and the effects of fetal exposure to this drug manifested in the offspring must be better understood to offer such patients suitable counseling. The present study was designed to determine whether fetal exposure to CP induces testicular cancer and/or gonadal toxicity in 129 and in 129.MOLF congenic (L1) mice. Exposure to CP on embryonic days 10.5 and 11.5 dramatically increased TGCT incidence to 28% in offspring of 129 mice (control value, 2%) and to 80% in the male offspring of L1 (control value 33%). These increases are similar to those observed in both lines of mice by radiation. In utero exposure to CP also significantly reduced testis weights at 4 weeks of age to ∼ 70% of control and induced atrophic seminiferous tubules in ∼ 30% of the testes. When the in utero CP-exposed 129 mice reached adulthood, there were significant reductions in testicular and epididymal sperm counts to 62% and 70%, respectively, of controls. In female offspring, CP caused the loss of 77% of primordial follicles and increased follicle growth activation. The results indicate that i) DNA damage is a common mechanism leading to induction of testicular cancer, ii) increased induction of testis cancer by external agents is proportional to the spontaneous incidence due to inherent genetic susceptibility, and iii) children exposed to radiation or DNA damaging chemotherapeutic agents in utero may have increased risks of developing testis cancer and having reduced spermatogenic potential or diminished reproductive lifespan.

    Full Text Available A case of bilateral persistent hyperplastic primary vitreous (PHPV in a 3-month-old male infant, who had bilateral leukokoria, is presented. The child was referred for imaging with a clinical suspicion of retinoblastoma. Gray-scale ultrasound evaluation revealed an echogenic band in the posterior segment of both globes, extending from the posterior surface of the lens capsule to the optic disc. Doppler examination revealed the presence of arterial flow in the band in both globes. Associated echogenic hemorrhage was also seen, which was confirmed by computed tomography. Most cases of PHPV are sporadic and unilateral, and bilateral PHPV is rare. The imaging features in this case suggest the diagnosis of bilateral PHPV and differentiate it from retinoblastoma. This entity, although infrequent, should be considered in the differential diagnosis while evaluating bilateral leukokoria.

    A 68-year-old man was referred to our outpatient clinic with left renal cell cancer and bladder cancer. He had undergone combination therapy comprising chemotherapy plus radiation therapy following radical orchiectomy for testicular cancer at the age of 48 years. The right testis could be felt within the scrotum, however the left testis could not. Blood tests showed no abnormality in regard to testicular tumor markers. Urine cytology was class V. Computed tomography revealed a 3.0 x 3.4 cm mass in the left kidney and a 4.5 x 1.5 cm mass in the left wall of the bladder. We made it a priority to treat the bladder cancer which was strongly suspected to be invasive cancer. At first the patient underwent radical cystectomy. Then left partial nephrectomy was carried out. Our case would appear to be the 24th case of triple primary urogenital cancer in Japan that consisted of left testicular cancer, left renal cancer and bladder cancer. Our case was also thought to be a case of secondary cancer that developed following treatment for testicular cancer. (author)

    Highlights: • Functional MRI in the characterization of testicular germ cell tumors was assessed. • ADC values proved useful in the characterization of testicular germ cell tumors. • Testicular germ cell tumors had similar enhancement patterns of dynamic MRI. - Abstract: Introduction: The aim of this study is to investigate the role of apparent diffusion coefficient (ADC) values and dynamic contrast enhancement (DCE) patterns in differentiating seminomas from nonseminomatous germ cell tumors (NSGCTs). Materials and methods: The MRI examinations of the scrotum of 26 men with histologically proven testicular GCTs were reviewed. DWI was performed in all patients, using a single shot, multi-slice spin-echo planar diffusion pulse sequence and b-values of 0 and 900 s/mm{sup 2}. Subtraction DCE-MRI was performed in 20 cases using a 3D fast-field echo sequence after gadolinium administration. Time-signal intensity curves were created and semi-quantitative parameters (peak enhancement, time to peak, wash-in and wash-out rate) were calculated. The Student's t-test was used to compare the mean values of ADC, peak enhancement, time to peak, wash-in and wash-out rate between seminomas and NSGCTs. ROC analysis was also performed. Results: Histopathology disclosed the presence of 15 seminomas and 11 NSGCTs. The mean ± s.d. of ADC values (× 10{sup −3} mm{sup 2}/s) of seminomas (0.59 ± 0.009) were significantly lower than those of NSGCTs (0.90 ± 0.33) (P = 0.01). The optimal ADC cut-off value was 0.68 × 10{sup −3} mm{sup 2}/s. No differences between the two groups were observed for peak enhancement (P = 0.18), time to peak (P = 0.63) wash-in rate (P = 0.32) and wash-out rate (P = 0.18). Conclusions: ADC values may be used to preoperatively differentiate seminomas from NSGCTs.

    The testicular cancer (TCa) incidence is increasing in many countries, with age-standardized incidence rates up to 7.8/100,000 men in the Western world, although reductions in mortality and increasingly high cure rates are being witnessed at the same time. In Africa, where rates are lower, presentation is often late and morbidity and mortality high. Given this scenario, awareness of testicular cancer and practice of testicular self-examination among future first response doctors is very important. This study was conducted to determine knowledge and attitude to testicular cancer, and practice of testicular self-examination (TSE) among final (6th) year medical students. In addition, the effect of an intervention in the form of a single PowerPoint® lecture, lasting 40 minutes with image content on testicular cancer and testicular self examination was assessed. Pre and post intervention administration of a self-administered structured pre tested questionnaire was performed on 151 medical students, 101 of whom returned answers (response rate of 66.8%). In the TC domain, there was a high level of awareness of testicular cancer, but poor knowledge of the age group most affected, with significant improvement post intervention (ptesticular self-examination pre-intervention was found considering the nature of the study group..Respondents had surprisingly weak/poor responses to the question “How important to men’s health is regular testicular self-examination?” Answers to the questions “Do you think it is worthwhile to examine your testis regularly?” and “Would you be interested in more information on testicular cancer and testicular self-examination?” were also suboptimal, but improved post intervention ptesticular cancer in the curricula of medical schools and other training institutions for health care personnel.

    2016-06-01

    Full Text Available Herein, we report a case of nontraumatic bilateral rhegmatogenous retinal detachment (RRD during external beam radiotherapy for nonocular tumor, presented as an observational case study in conjunction with a review of the relevant literature. A 65-year-old male was referred to our hospital due to bilateral RRD. He underwent a biopsy for a tumor of the left frontal lobe 4 months prior to presentation, and the tumor had been diagnosed as primary central nerve system B-cell type lymphoma. He received chemotherapy and external beam radiotherapy for 1 month. There were no traumatic episodes. Bilateral retinal detachment occurred during a series of radiotherapies. Simultaneous nontraumatic bilateral retinal detachment is rare. The effects of radiotherapy on ocular functionality, particularly in cases involving retinal adhesion and vitreous contraction, may include RRD. Thus, it is necessary to closely monitor the eyes of patients undergoing radiotherapy, particularly those undergoing surgery for retinal detachment and those with a history of photocoagulation for retinal tears, a relevant family history, or risk factors known to be associated with RRD.

    Testicular cancer typically affects young and middle-aged men. An educational video about prostate and testicular cancer was created in American Sign Language, with English open captioning and voice overlay, so that it could be viewed by audiences of diverse ages and hearing characteristics. This study recruited young Deaf (n = 85) and hearing (n = 90) adult males to help evaluate the educational value of the testicular cancer portion of this video. Participants completed surveys about their general, testicular, and total cancer knowledge before and after viewing the video. Although hearing men had higher pre-test scores than Deaf men, both Deaf and hearing men demonstrated significant increases in General, Testicular, and Total Cancer Knowledge scores after viewing the intervention video. Overall, results demonstrate the value of the video to Deaf and hearing men.

    A new type of testicular prosthesis made of silastic with an elliptical shape to mimic a normal testis was developed by our team and submitted for patenting in China. The prosthesis was produced in different sizes to imitate the normal testis of the patient. To investigate the effects and safety of the testicular prosthesis, 20 patients receiving testicular prosthesis implantation were recruited for this study. Follow-up after 6 months revealed no complications in the patients. All the patients answered that they were satisfied with their body image and the position of the implants, 19 patients were satisfied with the size and 16 patients were satisfied with the weight. These results show that the testicular prosthesis used in this study can meet patient's expectations. Patients undergoing orchiectomy should be offered the option to receive a testicular prosthesis implantation. The dimensions and weight of the available prosthetic implants should be further addressed to improve patient satisfaction.

    Testicular cancer processes a unique and clear miRNA expression signature. This differentiates testicular cancer from most other cancer types, which are usually more ambiguous when assigning miRNA patterns. As such, testicular cancer may represent a unique cancer type in which miRNAs find their use as biomarkers for cancer diagnosis and prognosis, with a potential to surpass the current available markers usually with low sensitivity. In this review, we present literature findings on miRNAs associated with testicular cancer, and discuss their potential diagnostic and prognostic values, as well as their potential as indicators of drug response in patients with testicular cancer.

    2006-02-01

    We used the nationwide Swedish Family-Cancer Database to analyse the risk for testicular cancer in offspring through parental and sibling probands. Among 0 to 70-year-old offspring, 4,586 patients had testicular cancer. Standardized incidence ratios for familial risk were 3.8-fold when a father and 7.6-fold when a brother had testicular cancer. Testicular cancer was associated with leukaemia, distal colon and kidney cancer, melanoma, connective tissue tumours and lung cancer in families. Non-seminoma was associated with maternal lung cancer but the risk was highest for the late-onset cases, providing no support to the theory of the in utero effect of maternal smoking on the son's risk of testicular cancer. However, the theory cannot be excluded but should be taken up for study when further data are available on maternal smoking. The high familial risk may be the product of shared childhood environment and heritable causes.

    2013-01-01

    Fournier gangrene (FG) is a necrotizing soft tissue infection involving the superficial and fascial planes of the perineum. In many cases of FG, debridement of the scrotum is necessary, leaving definitive management of the exposed testicles a significant surgical challenge. Frequent incidental trauma to the testicles can cause severe pain, especially in laborers. Practical surgical solutions are few and not well detailed. Various options exist, including creating a neoscrotum with adjacent thigh tissue, split-thickness skin grafts (STSGs), or even creating a subcutaneous thigh pocket. We describe a case of abdominal implantation of bilateral testicles for persistent testicular pain in a case where STSGs did not provide adequate protection, adjacent thigh skin was not available for creation of a neoscrotum, and significant cord contracture occurred. We detail the advantages and disadvantages of the commonly described techniques, including this approach, and how in select individuals this may be a suitable alternative.

    Full Text Available Prepubertal gynecomastia due to testis tumors is a very rare condition. Nearly 5% of the patients with testicular mass present with gynecomastia. Sertoli cell tumors are sporadic in 60% of the reported cases, while the remaining is a component of multiple neoplasia syndromes such as Peutz-Jeghers syndrome and Carney complex. We present a 4-year-old boy with gynecomastia due to Sertoli cell tumor with no evidence of Peutz-Jeghers syndrome or Carney complex.

    2005-01-01

    To evaluate the ultrasonographic findings of testicular teratoma arising in pre-pubertal children. We studied 6 cases in 5 patients with pathologically proven testicular teratoma. Ultrasonography was performed in all cases and MRI in 5 cases. The location, size, shape, margin and internal echo pattern of the lesion were evaluated on ultrasonography and the shape, signal intensity and presence or absence of contrast enhancement were evaluated on MRI. The shape of all cases was round or oval and the lesion size ranged from 0.5 to 3.5 cm (average, 1.7 cm). Four of 6 cases were seen as cystic lesions, Three of which were multilocular and one was unilocular. The cystic lesions were filled with echo-free fluid without any solid component. The inner wall and septa were minutely granulated. One of 6 cases was seen as a predominantly cystic lesion containing heterogeneous, high echoic portions. One case was seen as a heterogeneous mixed echoic lesion with dirty posterior sonic shadowing. Three of the 4 cases seen as a cyst on ultrasonography were also seen as a cyst on MRI. In one case seen as a predominantly cystic lesion on ultrasonography, the periphery of the lesion was hypointense and the center was hyperintense on T2-weighted image. The remaining case seen as a heterogeneous mixed echoic mass was markedly heterogeneous in signal intensity both on T2- and T1-weighted images and hyperintense fat components were noted. Contrast enhancement was not seen in any of the 4 cases. On ultrasonography, pre-pubertal testicular teratoma is commonly seen as a multilocular or unilocular cyst and a minutely granulated appearance is noted in the inner wall or septa of the cystic lesion

    Virtually all patients with Stage I testicular seminoma are cured regardless of postorchiectomy management. For patients treated with adjuvant radiotherapy, late toxicity is a major concern. However, toxicity may be limited by radiotherapy techniques that minimize radiation exposure of healthy normal tissues. This article is an evidence-based review that provides radiotherapy treatment planning recommendations for testicular seminoma. The minority of Stage I patients who choose adjuvant treatment over surveillance may be considered for (1) para-aortic irradiation to 20 Gy in 10 fractions, or (2) carboplatin chemotherapy consisting of area under the curve, AUC = 7 × 1−2 cycles. Two-dimensional radiotherapy based on bony anatomy is a simple and effective treatment for Stage IIA or IIB testicular seminoma. Centers with expertise in vascular and nodal anatomy may consider use of anteroposterior–posteroanterior fields based on three-dimensional conformal radiotherapy instead. For modified dog-leg fields delivering 20 Gy in 10 fractions, clinical studies support placement of the inferior border at the top of the acetabulum. Clinical and nodal mapping studies support placement of the superior border of all radiotherapy fields at the top of the T12 vertebral body. For Stage IIA and IIB patients, an anteroposterior–posteroanterior boost is then delivered to the adenopathy with a 2-cm margin to the block edge. The boost dose consists of 10 Gy in 5 fractions for Stage IIA and 16 Gy in 8 fractions for Stage IIB. Alternatively, bleomycin, etoposide, and cisplatin chemotherapy for 3 cycles or etoposide and cisplatin chemotherapy for 4 cycles may be delivered to Stage IIA or IIB patients (e.g., if they have a horseshoe kidney, inflammatory bowel disease, or a history of radiotherapy).

The minority of Stage I patients who choose adjuvant treatment over surveillance may be considered for (1) para-aortic irradiation to 20 Gy in 10 fractions, or (2) carboplatin chemotherapy consisting of area under the curve, AUC = 7 Multiplication-Sign 1-2 cycles. Two-dimensional radiotherapy based on bony anatomy is a simple and effective treatment for Stage IIA or IIB testicular seminoma. Centers with expertise in vascular and nodal anatomy may consider use of anteroposterior-posteroanterior fields based on three-dimensional conformal radiotherapy instead. For modified dog-leg fields delivering 20 Gy in 10 fractions, clinical studies support placement of the inferior border at the top of the acetabulum. Clinical and nodal mapping studies support placement of the superior border of all radiotherapy fields at the top of the T12 vertebral body. For Stage IIA and IIB patients, an anteroposterior-posteroanterior boost is then delivered to the adenopathy with a 2-cm margin to the block edge. The boost dose consists of 10 Gy in 5 fractions for Stage IIA and 16 Gy in 8 fractions for Stage IIB. Alternatively, bleomycin, etoposide, and cisplatin chemotherapy for 3 cycles or etoposide and cisplatin chemotherapy for 4 cycles may be delivered to Stage IIA or IIB patients (e.g., if they have a horseshoe kidney, inflammatory bowel disease, or a history of radiotherapy).

    Twenty eight patients with germ cell testicular pulmonary metastases received primary chemotherapy including bleomycin, etoposide, and cisplatin. Complete response (CR) was achieved in 21 (75%) patients, in 11 of them CR was achieved following chemotherapy alone. Post-chemotherapy surgery of residual mass performed in 12 (42.9%) patients with normalized serum tumor markers. Retroperitoneal lymph node dissection was performed in one patient, pulmonary surgery in four, and both post-chemotherapy treatments in 7 patients. Overall cure rate was 89.3%, 26 (92.9%) patients are still alive at a mean follow-up of 19.7+ months (range, 3-34+ months) after the treatment start. Two (7.1%) died: one of them due to disease progression during chemotherapy, and the second one due to postoperative complication (acute respiratory failure). Relapse of disease was observed in one patient 21 months following CR achievement, and sequential chemotherapy was introduced. Authors recommend surgical remove of all radiologically detected residual deposits, because the available imaging methods are not adequate for determining the histologic composition of residual mass, which is decisive for further therapy and has prognostic value.

    The minimum sperm count and quality that must be identified during microdissection testicular sperm extraction (micro-TESE) to deem the procedure successful remains to be established. We conducted a retrospective study of 81 consecutive men with non-obstructive azoospermia who underwent a primary (first) micro-TESE between March 2007 and October 2013. Final assessment of sperm recovery [reported on the day of (intracytoplasmic sperm injection) ICSI] was recorded as (i) successful (available spermatozoa for ICSI) or (ii) unsuccessful (no spermatozoa for ICSI). The decision to perform a unilateral (with limited or complete microdissection) or bilateral micro-TESE was guided by the intra-operative identification of sperm recovery (≥5 motile or non-motile sperm) from the first testicle. Overall, sperm recovery was successful in 56% (45/81) of the men. A unilateral micro-TESE was performed in 47% (38/81) of the men (based on intra-operative identification of sperm) and in 100% (38/38) of these men, spermatozoa was found on final assessment. In 42% (16/38) of the unilateral cases, a limited microdissection was performed (owing to the rapid intra-operative identification of sperm). The remaining 43 men underwent a bilateral micro-TESE and 16% (7/43) of these men had sperm identified on final assessment. The cumulative ICSI pregnancy rates (per cycle started and per embryo transfer) were 47% (21/45) and 60% (21/35), respectively, with a mean (±SD) of 1.9 ± 1.0 embryos transferred. The data demonstrate that intra-operative assessment of sperm recovery can correctly identify those men that require a unilateral micro-TESE. Moreover, the rapid identification of sperm recovery can allow some men to undergo a limited unilateral micro-TESE and avoid the need for complete testicular microdissection. © 2015 American Society of Andrology and European Academy of Andrology.

    We aimed to demonstrate the long term effectiveness of lycopene, a precursor of vitamin A, on the testes for ischemia-reperfusion injury. Seventy male Wistar albino rats were used for this experiment. The rats were divided into seven groups. Group 1 served as the control group; group 2 was sham-operated; group 3 received 20mg/kg/day lycopene (intraperitoneally); in group 4, the right testes of rats were kept torted for 2hours and then were detorted and the animals lived for three days; in group 5, the right testes of rats were kept torted for 2hours and then were detorted and the animals lived for ten days; in group 6, the right testes of the rats were kept torted for 2hours and then detorted and the animals received 20mg/kg/day lycopene (intraperitoneally) for three days; in group 7, the right testes of the rats were kept torted for 2hours and then were detorted and the animals received 20mg/kg/day lycopene (intraperitoneally) for ten days. Lycopene was used intraperitoneally. Some of the testes tissues were used for biochemical analyses and the other tissues were used for histological procedures. The Johnsen's score was used for seminiferous tubule deterioration. The TUNEL method was utilized to show apoptosis of testicular tissue. Testosterone levels were measured from blood samples and SOD, MDA, TNF-α, IL-1β and IL-6 measurements were recorded from tissue samples. The results were analyzed statistically. In groups 1, 2 and 3 there was normal testicular structure. Rats in groups 4 and 5 had damaged testicular tissues. In groups 6 and 7, in which we used lycopene, the testes were not better than those in groups 4 and 5. The MSTD and JTBS values were better in group 6, but not in group 7 among the torsion groups. As a result, MDA, SOD, TNF-α and IL-1β were increased and serum testosterone and IL-6 levels were decreased in groups 4 and 5 compared to group 1. There was no improvement in the groups treated with lycopene for therapeutic purposes. It was shown that

    2018-03-01

    There were an estimated 8720 new cases of testicular cancer (TC) in the United States in 2016. The cause of the disease is complex, with several environmental and genetic risk factors. Although rare, the incidence has been steadily increasing. Fortunately, substantial advances in treatment have occurred over the last few decades, making TC one of the most curable malignancies. However, because TC typically occurs in younger men, considerations of the treatment impact on fertility, quality of life, and long-term toxicity are paramount; an individualized approach must be taken with patients based on their clinical and pathologic findings.

    BACKGROUND: Juvenile nasopharyngeal angiofibroma is a benign, vascular tumour that primarily occurs in adolescent males. Despite its benign nature, aggressive growth patterns can cause potential life-threatening complications. Juvenile nasopharyngeal angiofibroma is normally unilateral, originating...... from the sphenopalatine artery, but bilateral symptoms can occur if a large tumour extends to the contralateral side of the nasopharynx. This paper presents the first reported case of true bilateral extensive juvenile nasopharyngeal angiofibroma involving clinically challenging pre-surgical planning...... embolisation. Radical removal performed as one-step, computer-assisted functional endoscopic sinus surgery was performed. The follow-up period was uncomplicated. CONCLUSION: This case illustrates the importance of suspecting bilateral juvenile nasopharyngeal angiofibroma in patients presenting with bilateral...

    2013-01-01

    Full Text Available Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

    Highlights: ► Spermatogenesis is closely associated with the balance between germ cells proliferation and apoptosis. ► Numerous studies have documented the direct action of ghrelin in the modulation of apoptosis in different cell types. ► Ghrelin may be considered as a modulator of spermatogenesis in normal adult rats. ► Ghrelin may be potentially implicated for abnormal spermatogenesis in some testicular germ cell tumors. -- Abstract: Under normal condition in the most mammals, spermatogenesis is closely associated with the balance between germ cells proliferation and apoptosis. The present study was designed to determine the effects of ghrelin treatment on in vivo quality and quantity expression of apoptosis and proliferation specific indices in rat testicular germ cells. Twenty eight adult normal rats were subdivided into equal control and treatment groups. Treatment group received 3 nmol of ghrelin as subcutaneous injection for 30 consecutive days or vehicle to the control animals. The rats from each group (n = 7) were killed on days 10 and 30 and their testes were taken for immunocytochemical evaluation and caspase-3 assay. Immunohistochemical analysis indicated that the accumulations of Bax and PCNA peptides are generally more prominent in spermatocytes and spermatogonia of both groups. Likewise, the mean percentage of immunoreactive spermatocytes against Bax increased (P 0.05). Upstream of Bax substance parallel to down-regulation of PCNA demonstrate that ghrelin may prevent massive accumulation of germ cells during normal spermatogenesis. These observations also indicate that ghrelin may be considered as a modulator of spermatogenesis in normal adult rats and could be potentially implicated for abnormal spermatogenesis in some testicular germ cell tumors.

    We determined the influence of cryptorchidism on testicular volume and masculine identity in young men living in a community. Of the 27,202 men aged 20 years dwelling in the community, we randomly selected a 10% sampling fraction of whom 2,080 men (a response rate of 77.0%) agreed to participate in the study. All volunteers underwent a standard evaluation, including a detailed medical history and physical examination. For the evaluation of the influence of cryptorchidism on masculine identity, we used the Bem Sex Role Inventory (BSRI). Among participants, 38 (1.8%) had cryptorchidism or a history of surgery for cryptorchidism (right 15, left 21, bilateral 2). In total, 29 had had undergone surgery (mean age at the time of operation; 8.9+/-3.9 years, range; 2-19 years). Of 25 men who had undergone orchiopexy due to unilateral cryptorchidism, the testicular volume of the affected side was significantly smaller than that of the contralateral side. Of the 36 patients with unilateral cryptorchidism, the contralateral testicular volume of men who had undergone orchiopexy was not different with that of those who had undergone orchiectomy or had not undergone surgery. When we compared the scores for masculinity and femininity using the BSRI between men with and without testis in the scrotum, there were no differences between the two groups. Our results demonstrate that delayed orchiopexy does not improve the testicular volume of the affected side or the masculine identity in men with unilateral cryptorchidism. In addition, these findings suggest that there is a need to increase the awareness of cryptorchidism among all parties involved in the health care of children.

    Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith-Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with anteverted nose, bilateral bronchial stenosis due to lack of cartilage, bilateral obstructive renal dysplasia and NB with glomeruloid features. The infant had visceromegaly, but neither gigantism nor hemihypertrophy. Immunohistochemistry for PAX2 (Paired box gene-2) and WT-1 (Wilms Tumor 1) were strongly positive in the areas of NB. GLEPP-1 (Glomerular Epithelial Protein) did not stain the areas of NB with a glomeruloid appearance, but was positive in the renal glomeruli as expected. We found neither associated bronchial stenosis nor the histology of NB resembling giant glomeruli in any of the reported cases of NB.

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

    Rhabdomyosarcoma is the most common sarcoma of soft tissues in childhood and adolescence, with an annual incidence of 4-7 cases per million children aged 15. Embryonal rhabdomyosarcoma is common in adults younger than 30 years, and are usually presented as a large painless, palpable mass (> 5cm). Survival in the case of paratesticular sarcoma in men is approximately 50%. Male 27 years of age with no history of importance, was seen in a clinic with an increased, painless, left testicular volume 3 years onset. Intrascrotal left testicle increased volume, with dimensions of 20×12×8cm, a stone and left inguinal node in induratum measuring 2×2cm. Microscopically, it showed a pattern of an embryonal rhabdomyosarcoma with left inguinal node metastases. Early diagnosis of testicular tumours, and especially of primary intratesticular rhabdomyosarcomas, and aggressive surgical treatment in combination with chemotherapy reduces the incidence of local recurrence and may improve the rate of disease-free survival and overall survival in adult patients with metastases.

    The etiology of testicular cancer is largely unexplained. Research has mainly focused on prenatal exposures, especially to sex hormones, while less attention has been paid to exposures that may act also postnatally. As baldness has been previously associated with testicular cancer risk we focused on baldness and body hairiness, which are both associated with androgen activity. We used data of the Postnatal Exposures and Male Health (EPSAM) study, a case-control study on testicular cancer conducted in the Province of Turin, Italy, involving cases diagnosed between 1997 and 2008. Information was collected using mailed questionnaires. Analyses included 255 cases and 459 controls. We calculated ORs and 95% CIs to estimate testicular cancer risk among those who developed baldness and among those with body hairiness. We found an inverse association between testicular cancer and baldness (OR: 0.67, 95% CI: 0.46-0.98) and body hairiness (OR: 0.78, 95% CI: 0.53-1.16), although the latter had wider CIs. The inverse association between baldness and testicular cancer is consistent with the results from previous studies. These results suggest that androgens activity may influence testicular cancer risk. © 2016 American Society of Andrology and European Academy of Andrology.

    2012-11-01

    Full Text Available In the last decades, studies in rodents have highlighted links between in utero and/or neonatal exposures to molecules that alter endocrine functions and the development of genital tract abnormalities, such as cryptorchidism, hypospadias, and impaired spermatogenesis. Most of these molecules, called endocrine disrupters (EDs exert estrogenic and/or antiandrogenic activities. These data led to the hypothesis of the Testicular Dysgenesis Syndrome which postulates that these disorders are one clinical entity and are linked by epidemiological and pathophysiological relations. Futhermore, infertility has been stated as a risk factor for testicular cancer. The incidence of testicular cancer has been increasing over the past decades. Most of testicular germ cell cancers develop through a pre-invasive carcinoma in situ (CIS from fetal germ cells (primordial germ cell or gonocyte. During their development, fetal germ cells undergo epigenetic modifications. Interestingly, several lines of evidence have shown that gene regulation through epigenetic mechanisms (DNA and histone modifications plays an important role in normal development as well as in various diseases, including testicular cancer.Here we will review chromatin modifications which can affect testicular physiology leading to the development of testicular cancer; and highlight potential molecular pathways involved in these alterations in the context of environmental exposures.

    Economou Nicolas C

    2006-10-01

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

Ophthalmologists should be aware that patients with achondroplasia who complain of poor vision should be suspected of having keratoconus once other more common conditions are ruled out.

    To describe the clinical and pathological characteristics and oncological outcomes of testicular cancer diagnosed in Japan, we report the results of the testicular cancer registration carried out by the Japanese Urological Association. Testicular cancer survey was conducted by the Japanese Urological Association in 2011 to register newly diagnosed testicular cancers in 2005 and 2008. The survey included details such as age, presenting symptoms, physical examination findings, tumor markers, histopathology, clinical stage, initial treatment and clinical outcomes. We analyzed 1121 cases of testicular primary germ cell tumor among 1157 registered patients. The median age was 37.0 years. Seminomas and non-seminomatous germ cell tumors accounted for 61.9% and 38.1%, respectively. Measurements of tumor markers were documented in 98.6% of the patients; however, there was an unsatisfactory uniform measurement of human chorionic gonadotropin, which made it difficult to evaluate the International Germ Cell Consensus Classification in all patients. The 1- and 3-year overall survival rates from the entire cohort were 98.3% and 96.8%, respectively. According to the International Germ Cell Consensus Classification, 3-year overall survival rates in the good, intermediate, and poor prognosis group were 99.1%, 100% and 79.9%, respectively. The present report is the first large-scale study of the characteristics and survival of testicular cancer patients in Japan based on multi-institutional registry data, and showed a good prognosis even in an advanced stage. The improved survival attributed substantially to accurate diagnosis and effective multimodal treatment. © 2014 The Japanese Urological Association.

    Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases and patellar tendinopathy. The authors report a rare case of a 34-year-old man with simultaneous bilateral rupture of the patellar tendon caused by minor trauma. The patient is a retired basketball player with no past complaints of chronic knee pain and a history of steroid use. Surgical management consisted in primary end-to-end tendon repair protected temporarily with cerclage wiring, followed by a short immobilization period and intensive rehabilitation program. Five months after surgery, the patient was able to fully participate in sport activities.
