    The testicular epidermoid cyst is an uncommon benign tumor that represents 1% to 2% of resected testicular masses. The observation of the characteristic ultrasonographic features of these lesions facilitates their diagnosis and may make it possible to perform enucleation, obviating the need for orchidectomy. We present two cases in which the testicular epidermoid cysts were diagnosed preoperatively and their presence confirmed after conservative surgery. We review the literature concerning imaging studies and the management of these lesions. (Author) 9 refs.

    Epidermoid cyst of the testis is an uncommon benign tumor that can be treated by organ-preserving surgery when diagnosed preoperatively. Although some sonographic characteristics may be suggestive of epidermoid cysts, sonography is not completely diagnostic. Magnetic resonance imaging (MRI) findings may provide support for the diagnosis of epidermoid cysts. The MRI findings of testicular epidermoid cysts have been reported as either bull's eye or target in appearance, or with signal intensity characteristics more typical of a cystic lesion. In this paper, we present typical sonographic and unusual MRI findings of a testicular epidermoid cyst.

    Epidermoid cyst of the testis is an uncommon benign tumour, with an overall incidence of 1-2 % of all resected testicular masses. When imaging findings suggest that an intratesticular mass is likely to be an epidermoid cyst, conservative management (enucleation with testicular preservation) can be performed rather than orchidectomy. This case report records an epidermoid cyst in a 12-year-old boy in whom the US findings allowed testis-sparing surgery instead of orchidectomy. (orig.)

    Introducción: los tumores epidermoides representan 1 % de las neoplasias intracraneales; el ángulo pontocerebeloso es la localización más frecuente y en el cuarto ventrículo son raros. Casos clínicos: caso 1: mujer de 22 años de edad con cefalea intensa de tres meses de evolución. Al ingreso se identificó hipertensión endocraneana. La tomografía mostró hidrocefalia con aumento del volumen del cuarto ventrículo. La paciente fue tratada con derivación ventrículo-peritoneal; posteriormente se extirpó tumoración encapsulada de aspecto perlado. El estudio histológico indicó tumor epidermoide en el cuarto ventrículo. Caso 2: mujer de 44 años de edad con vértigo ocasional de cinco años de evolución, así como con diploplía y disfagia intermitentes de tres años de evolución. Al ingresó se identificó paresia bilateral de los nervios craneales VI y VII. La tomografía computarizada y la resonancia magnética mostraron lesión en el cuatro ventrículo. El manejo fue quirúrgico. Conclusiones: la resonancia magnética es el estudio diagnóstico específico para el diagnóstico del tumor epidermoide del cuarto ventrículo que, sin embargo, puede confundirse con neurocisticercosis. Están indicados la exéresis del quiste y el tratamiento de la hidrocefalia.

    Scrotal sonography is a valuable tool for assessing the testis and surrounding structures, and has become the imaging modality of choice for evaluation of the scrotum. Scrotal sonography is also helpful for differentiating cystic from slid mass and testicular from extratesticular mass, but is sometimes difficult in differentiating malignant tumor from various benign conditions such as epidermoid cyst, focal orchitis, testicular hematoma, and abscess. We demonstrate the sonographic findings of the various testicular mass, and correlation with pathologic findings.

  8. Recurrent intramedullary epidermoid cyst of conus medullaris.

    LENUS (Irish Health Repository)

    Fleming, Christina

    2011-01-01

    Spinal intramedullary epidermoid cyst is a rare condition. Recurrent epidermoid cyst in the spine cord is known to occur. The authors describe a case of recurrent conus medullaris epidermoid cyst in a 24-year-old female. She initially presented at 7 years of age with bladder disturbance in the form of diurnal enuresis and recurrent urinary tract infection. MRI lumbar spine revealed a 4 cm conus medullaris epidermoid cyst. Since the initial presentation, the cyst had recurred seven times in the same location and she underwent surgical intervention in the form of exploration and debulking. This benign condition, owing to its anatomical location, has posed a surgical and overall management challenge. This occurrence is better managed in a tertiary-care centre requiring multi-disciplinary treatment approach.

    2010-01-01

    Full Text Available Background: Testicular tumors in the pediatric population are distinct from those of the adults. In contrast to the prevalence data reported in tumor registries, several studies have shown that a majority of the prepubertal testis tumors are benign. We retrospectively analyzed a series of prepubertal testicular tumors. Materials and Methods: A retrospective review of all testicular tumors at our institution was done from Jan 1999 to Dec 2008. Data relating to presentation, evaluation, and management were collected. Results: A total of 22 children with prepubertal testicular tumors were identified. The mean age at presentation was 4.6 years. Mature teratoma, epidermoid cysts, immature teratoma, and yolk sac tumor accounted for 49.94%, 13.62%, 9.08%, and 18.16%, respectively. All surgeries were successful with respect to cancer control and testicular preservation. Conclusions: Benign tumors formed the majority (72.64% of the tumors that were encountered, with yolk sac tumors (18.16% being a minority. Testicular preserving surgery appears to be a feasible option for benign tumors and is safe and efficacious in long-term follow-up.

    2008-10-01

    The cistern of the velum interpositum is a space located between the corpus callosum dorsally and the roof of the third ventricle ventrally. Lesions located within the velum interpositum are rare and include meningiomas, pilocytic astrocytomas, atypical teratoid/rhabdoid tumors and arachnoid cysts. Epidermoid cysts in this location have not been reported previously. We report the clinical and radiological features of two patients with epidermoid cysts located in the velum interpositum. The patients presented with gait difficulty and features of raised intracranial pressure and magnetic resonance imaging demonstrated large tumors in the velum interpositum with intensities suggestive of epidermoid cysts. There was ventral displacement of the internal cerebral veins and dorsal displacement of the corpus callosum in keeping with a mass in the velum interpositum. Tumors of the third ventricle displace the internal cerebral veins dorsally. A transcallosal approach was used in both patients to effectively excise the tumors.

    Full Text Available Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid.

    Full Text Available Epidermoids are inclusion tumors of the central nervous system and are rare, benign slow-growing tumors. They are estimated to constitute 0.5-1.8% of the brain tumors and have an affinity for the subarachnoid cisterns at the base of the brain, the suprasellar cistern being one of the most favoured sites. We report a case of suprasellar epidermoid in a 2-year-old male child with an unusual CT and MRI appearance, who presented to us in February 1995 with features of precocious puberty. In October 2004, at the age of 11 years, he presented with symptoms and signs of raised ICP.

    Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid. Despite their benign presentation, these cysts can cause functional limitations, requiring special clinical attention for extensive lesions located in regions that preserve vital structures. This paper aims to report a case of epidermoid cyst in patient with swallowing and breathing difficulty, highlighting the clinical and surgical planning. PMID:26180645

    2014-01-01

    Full Text Available Background. Orbital epidermoids form a rare pathological entity that is separate from dermoid cysts. They have variable clinical and radiological presentations and they should be considered in the differential diagnosis of orbital cystic lesions. This work describes the various clinical and radiological presentations of 17 cases of epidermoid cysts and the surgical outcome. Method. A prospective interventional study was conducted on 17 patients diagnosed with epidermoid cysts. Patients’ symptoms and signs were recorded; CT scan was done for all patients. All lesions were removed through anterior orbitotomy and histopathological diagnosis confirmed. Results. Mean age of patients was 16.3 years ±  10.54. Main complaints were lid swelling, masses, ocular dissimilarity, chronic pain, and ocular protrusion. Clinical signs varied from lid swelling and masses in all cases to proptosis, globe displacement, limitation of ocular motility, and scars. Radiological findings ranged from homogenous hypodense masses (58.8% to homogenous radiolucent (17.6% and heterogenous masses (23.5%. No recurrences following surgeries were reported throughout the follow-up (mean 18.8 months ±  0.72. Conclusion. Deep orbital epidemoid cysts are a separate entity that can behave like deep orbital epidermoid; however, they usually present at a relatively older age. They can be associated with increased orbital volume but not necessarily related to bony sutures.

    Epidermoid cysts are malformations that are rarely observed in the submental region. Imaging has an important role in surgical planning according to the size and location of the cyst in relation to geniohyoid and mylohyoid muscles. This article reports the case of a 15-year-old female patient complaining of submental swelling. The differential diagnosis included infection, tumor, ranula, and abnormalities during embryonic development. The lesion was surgically excised using an extra-oral approach. The histopathological examination revealed a cyst wall lined with stratified squamous epithelium with the presence of several horny scales consistent with the diagnosis of an epidermoid cyst. No recurrences were found after 1 year of follow-up. PMID:27547744

    Full Text Available Abstract Epidermoid and dermoid cysts represent less than 0.01% of all oral cavity cysts. The cysts can be defined as epidermoid when the lining presents only epithelium, dermoid cysts when skin adnexa are found, and teratoid cysts when other tissue such as muscle, cartilage, and bone are present. In this article, we present the case of an epidermoid cyst, with an oral as well as a submental component, in an 11 year old boy who presented with complaints of a mass in the oral cavity, difficulty chewing and swallowing of solid foods for about 3 years. He was admitted to the otolaryngology department. On examination, a mass displacing the tongue superiorly and posteriorly was noticed. An MRI scan was done and showed a 40 × 35 mm well-circumscribed non-enhancing cystic mass extending from the sublingual area to the level of the thyroid notch. The content of the cyst was homogenous. On examining the neck, a firm swelling was also noticed in the submental area, extending down to the thyroid notch. Under general anesthesia and with nasotracheal intubation, the patient underwent surgical removal of the mass. Extraorally, a midline submental horizontal incision was performed through the mucosa overlying the swelling and the cyst was dissected from the surrounding tissues and removed. On histological examination, acidophilic stratum corneum and basophilic dot like staining of stratum granulosum, which is the hallmark of an epidermoid cyst, were seen. The patient did well postoperatively, and no recurrence was noticed at the 6-months follow-up.

    Full Text Available Dermoid and epidermoid cysts in the oral cavity frequently develop in the midline or sublingual region of the floor of the mouth. Here, we report a rare case of an epidermoid cyst in the submandibular region. The patient was a 69-year-old man with a chief complaint of a mass in the right submandibular region. A mobile, elastic, relatively soft mass without tenderness was palpable in this region. The skin covering the mass was normal. MRI showed a cystic lesion measuring 3.5 × 3.0 cm under the platysma in the right submandibular region. Cystectomy was performed under general anesthesia. There was no adhesion to surrounding tissue and the right submandibular gland was preserved. The surgical specimen was cystic and contained soybean cord-like materials. Histopathologically, the cyst wall was lined by stratified squamous epithelium with no skin appendage, suggesting an epidermoid cyst. The postoperative course was uneventful and without recurrence after 28 months.

  13. Orbital dermoid and epidermoid cysts: Case study

    Directory of Open Access Journals (Sweden)

    Veselinović Dragan

    2010-01-01

    Full Text Available Introduction. Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. They are described as both superficial and deep formations with most frequently slow intermittent growth. Apart from aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also an optical nerve compression syndrome. Case Outline. In this paper, we described a child with a congenital orbital dermoid cyst localized in the upper-nasal quadrant that was showing signs of a gradual enlargement and progression. The computerized tomography revealed a cyst of 1.5-2.0 cm in size. At the Maxillofacial Surgery Hospital in Niš, the dermoid cyst was extirpated in toto after orbitotomy performed by superciliary approach. Postoperative course was uneventful, without inflammation signs, and after two weeks excellent functional and aesthetic effects were achieved. Conclusion. Before the decision to treat the dermoid and epidermoid cysts operatively, a detailed diagnostic procedure was necessary to be done in order to locate the cyst precisely and determine its size and possible propagation into the surrounding periorbital structures. Apart from cosmetic indications, operative procedures are recommended in the case of cysts with constant progressions, which cause the pressure to the eye lobe, lead to motility disturbances and indirectly compress the optical nerve and branches of the cranial nerves III, IV and VI.

    Testicular cancer, which predominantly occurs in young men, has become increasingly common; it is presently the most common malignancy in men aged 20-34. Despite a lack of knowledge of aetiology, empirical advances, particularly in the management of patients with advanced disease, have been dramatic. Prior to the development of effective chemotherapy in the 1970s, less than 10% of men with metastatic non-seminomatous germ cell tumours were cured; nowadays approximately 90% of patients are potentially curable. The introduction of effective chemotherapy has led to a reappraisal of surgery and radiotherapy in the management of early stage disease and the introduction of a policy of surveillance in patients without evidence of metastases at the time of removal of the primary tumour. Following chemotherapy, surgery is required in approximately 25% of patients with advanced disease to excise residual masses, which in one-fifth of cases will show evidence of residual malignancy. In a proportion of patients, testicular cancer develops on a background of long-standing infertility, whereas in many men there is temporary oligospermia, despite a previous history of fertility. The majority of patients with prior evidence of spermatogenesis recover this function following chemotherapy and there is no evidence that children fathered by such patients have an increased risk of malformation. Despite physician optimism and excellent prospects for cure, significant psycho-social morbidity is associated with the diagnosis and treatment of testicular cancer. Factors contributing to this are being identified and will lead, hopefully, to the minimisation of such problems by appropriate intervention.

    Background: Epidermoid and dermoid cyst comprise <1% of spinal tumors and may be congenital (hamartoma) or acquired (iatrogenic) in origin. Epidermoid cysts within the neuraxis are rare benign neoplasms that are most commonly located in the intracranial region. Case Description: Here, we report the a case of an acquired intradural extramedullary epidermoid cyst involving the thoracic region in an adult female who had no associated history of an accompanying congenital spinal deformity. Conclusion: Early diagnosis and immediate surgical intervention reduce patient morbidity. Near complete or subtotal excision of the cyst wall is warranted to prevent inadvertent injury to the spinal cord thus minimizing neurological morbidity. PMID:26904369

    Full Text Available Hemifacial Spasm (HS occurs idiopathically or secondary to the lesions compressing the root exit zone of the facial nerve symptomatically. Symptomatic HS is generally due to vascular compression. We report on a 23-year-old male with right sided HS for a month. Magnetic resonance imaging (MRI of the brain revealed a well-demarcated epidermoid cyst in the right cerebellopontine cistern. It was hypointense on T1-weighted imaging, hyperintense on T2-weighted imaging without contrast enhancement, hyperintense on DWI, and slightly hypointense on ADC relative to the brain. Although it caused shifting of the pons and medulla to the left side and compression of the right cerebellar peduncles and fourth ventricle, the sole symptom of the patient was HS. Clinicians are advised to request MRI/scan for brainstem lesions from the patients with HS. Epidermoid cysts in cerebellopontine cistern may present with HS as the sole symptom.

    Pediatric neck masses represent a variety of differential diagnoses. A common pathology in pediatric cystic neck tumors include ranulas, mucus retention cysts due to salivary gland obstruction. Epidermoid cysts are lesions infrequently encountered in the pediatric population and may appear similarly to ranulas on computed tomography imaging. MRI more easily differentiates these masses, and should therefore be the preferred imaging modality. Due to their distinct intraoperative management, ranulas and epidermoid cysts should be distinguished preoperatively through proper workup.

    2016-01-01

    Full Text Available Epidermoid cysts (ECs are uncommon, benign cystic lesions derived from the entrapment of surface epithelium or more often from the aberrant healing of infundibular epithelium during an episode of follicular inflammation. ECs occur anywhere on the body, particularly along embryonic fusion lines, most commonly on the face, scalp, neck, chest and upper back. Head and neck ECs constitute only about 7%, whereas only 1.6% of ECs are reported in the oral cavity. They comprise <0.01% of all the oral cysts. Floor of the mouth, tongue, lips, palate, jaws, etc., are some of the reported sites of ECs in the oral cavity. Microscopically, ECs are lined with plain stratified squamous epithelium filled with laminated layers of keratin. Here, we report two rare cases of ECs, one occurring in the gingival aspect and other in the lower third of face. The cases are reported due to rarity of ECs in the head and neck region.

    Full Text Available Epidermoid cysts of the central nervous system are uncommon conditions, which are frequently located in the cerebellopontine angle and around the pons. They are covered with keratinized squamous epithelium and keratin lamella, which give its contents a soft, white-pearly appearance. Epidermoid cysts are mostly originated from malformations, presumably associated with surface elements of the nervous system ectoderm during the closure of the neural groove or formation of secondary cerebral vesicles. The authors describe a case of epidermoid cyst in the posterior fossa causing hydrocephalus and review morphologic and diagnostic criteria of this lesion.Os cistos epidermoides do sistema nervoso central (SNC são condições incomuns, estando localizados mais frequentemente no ângulo pontocerebelar e ao redor da ponte.

    Full Text Available The early epidermoid carcinoma is considered the strangest breast tumor with an incidence that only represents from 0,04 to 0,075 % out of all malignant tumors of the breast. It is a variety of the metaplastic carcinoma constituted by pavement keratinizing cells with an inconstant presence of fusocellular sarcomatoid elements, that reach great volume and frequently present as cystic tumours that may be confused with a breast abscess. This is the case of a 41 year-old white female from Cienfuegos municipality, Cuba, who presented to the provincial Mastology consultation because of a two month follow up of a 5 cm tumor in the right outer upper quadrant of her breast. Surgical removal of the tumor was performed and the result of the biopsy revealed a little differentiated epidermoid carcinoma. At present the patient has no metastasis and receives treatment at the outpatient. Its unusual presentation has led this case to be published. El carcinoma epidermoide primitivo es considerado el tumor más raro de la mama, con una incidencia que representa solo del 0,04 al 0,075 % de todos los tumores malignos de mama.

    Abstract Rationale: There were a few case reports concerning epidermoid tumor coexisted with multiple cerebral aneurysms. Here, we present one case of coexistence of intracranial epidermoid tumor and multiple cerebral aneurysms and performed a literature review. Patient concerns: A 42 years old male patient was admitted to our institution with complaints of headache and dizziness. Interventions: The radiological examinations showed a hypointense lesion in the right parasellar and petrous apex region and an ipsilateral saccular aneurysm originated from the M2–M3 junction of the right middle cerebral artery (MCA) and a saccular aneurysm of the clinoid segment of right internal carotid artery (ICA). Interventions: The patients underwent a right frontotemporal approach for removal of the epidermoid tumor and clipping of the MCA aneurysm in one stage. The aneurysm located at the clinoid segment of ICA was invisible and untreated during operation. Outcomes: No postoperative complications were found in the patient. The patient's follow up after 5 years of surgical treatment was uneventful, and the untreated aneurysm remains stable. Lessons: The coexistence of intracranial epidermoid tumor and cerebral aneurysm is a rare event. The secondly inflammation in cerebral arterial wall may be responsible for the aneurysm formation. Surgical treatment of the intracranial epidermoid tumor and cerebral aneurysm repair may be an optimal scheme in one stage. PMID:28151901

    Epidermoid cysts, dermoid cysts and teratoid cysts are cystic malformations lined with squamous epithelium. They present as soft nodular lesions with a sessile base. Their prevalence is 7% in head and neck patients and 1.6% within the oral cavity. The authors present a case series of 21 patients with dermoid and epidermoid cysts who underwent surgical removal. One year of follow-up was carried out without evidence of recurrence. The removal of these cysts is of great concern as it can cause serious social stigma, aesthetic and functional impairment, dysphagia and dysphonia.

    Clitoromegaly is uncommon. It is mostly congenital, hormonal or tumoral. Epidermoid cyst is rare. It can be the consequence of trauma, but in some situations the cyst can be non-traumatic. We report the case of a 53-year-old woman who presented a misdiagnosis of clitoromegaly due to hormonal condition. Surgical exploration has highlighted an epidermoid cyst. This observation underlines the importance to evoke a cystic origin for clitoral hypertrophy and encourages us to propose imaging (ultrasound, MRI) in case of etiological doubt. The preoperative diagnosis must be made to preserve vascularization and innervation of the clitoris.

    Full Text Available Introduction. Vulvar cyst in adolescent girls is very uncommon. Epidermoid cyst can be seen in many sites including face, trunk, and extremities but its occurrence in vulva is uncommon. This is the first case of epidermoid cyst of vulva reported in an adolescent girl. Case. A 17-year-old, adolescent girl admitted to our gynecology outpatient clinic with a complaint of painful and palpable mass in her vulva. On examination, a giant mass located in left vulva and labia majora with 11 cm in diameter was seen. The magnetic resonance imaging (MRI showed a well-defined cystic mass without contrast enhancement. The surgery was advised to the patient and the pathologic examination of mass revealed vulvar epidermoid cyst. Discussion. Vulvar cysts generally grow slowly and the main etiologies are vulvar trauma and surgical interventions including episiotomy and female circumcision in some culture. The exact treatment is total surgical excision and pathologic examination. MRI is an important imaging modality for detection of extension to deep perineal tissue and localization of mass in vulva especially in giant ones. Conclusion. Although vulvar mass in adolescents is rare, the epidermoid cyst with benign origin should be kept in mind.

    We have reported a case of paratrigeminal epidermoid originated in the Meckel's cave. A 30 years old man was admitted to the department of neurosurgery with chief complaints of continuous right facial pain and numbness of entire right side of the face of three years duration. The positive neurological findings were hypesthesia over the distribution of the right trigeminal nerve, absence of the right corneal reflex and nystagmus on left lateral gaze. Caloric response was absent on the right side, however the audiogram showed normal. Cerebrospinal fluid examination was within normal limit. Electromyography showed giant spike in the right masseter and temporal muscles. Radiogram of the skull revealed a bone-destroying lesion over the medial florr of the right middle fossa involving the apex of the petrous bone (Fig 1). Right carotid angiography showed straightening and forward displacement of C4- C5 portion of the carotid siphon in the lateral view, and vertebral angiography showed displacement of basilar artery to the left side, upward displacement of the right posterior cerebral and superior cerebellar artery in the frontal view (Fig. 2, 3). At the time of operation, an epidermoid was identified in the Meckel's cave and totally removed microsurgically. Small amount of the tumor extending into the posterior fossa was also removed (Fig. 4, 5, 6, 7). Postoperative course was uneventfull except for an episode of headache and high fever of short duration, suggesting the signs of meningial irritation. Two months postoperativelly patient was relived of facial pain and was discharged with sensory impairment of the right trigeminal nerve distribution. Only 11 cases of paratrigeminal epidermoid, including the cases localized in the Meckel's cave have been reported in the past literatures (Table 1). In this paper we have discussed about the symptomatology and clinical data of paratrigeminal epidermoid and compared with those of trigeminal neurinoma, and meningioma originated

    Full Text Available Two rare cases of intragonadal epidermoid inclusion cysts are described. Their etiology remains controversial and a possible hypothesis is monodermal abortive teratomas, with no mesodermal and endodermal components. As the ultrasound test results were inconclusive, it became difficult to rule out the possibility of neoplasm. Therefore, patients were submitted to radical therapy. The definitive diagnosis for both cases was provided by the anatomopathological examination.

    Full Text Available A case of sublingual epidermoid cyst presenting distinctive magnetic resonance imaging (MRI findings is described. A 39-year-old man presented to our hospital with a three months progressive left submandibular swelling, difficulty moving his tongue, and snoring. Preoperative evaluation with MRI and fine needle aspiration cytology (FNAC revealed that the heterogeneous cystic lesion contained the squamous cells, which is compatible with ectodermal tissue. The mass was located above the mylohyoid muscle and spread to the pharyngeal space. By considering the size, infection history, patient age, and location, the cyst was completely resected under general anesthesia via cervical approach without any complication. Histopathologically, the cyst wall was lined by stratified squamous epithelium with no skin appendage, suggesting an epidermoid cyst. Ultrasound (US, MRI and FNAC were very useful of the preoperative diagnosis for oral and sublingual lesion. The postoperative course was uneventful and without recurrence after 24 months. This case showed that epidermoid cysts formed the rarely heterogeneous cystic tumor and it underlined usefulness of preoperative diagnosis, such as US, MRI and FNAC for oral and sublingual tumor.

    In the clinical situation of an acute scrotum, differentiation between different reasons for scrotal pain may be crucial in certain cases. Beside clinical examination and laboratory tests, Color Doppler sonography is routinely applied. Testicular scintigraphy can only be suggested as a complementary tool if it is available as an emergency procedure. Acute testicular torsion that has already been reliably diagnosed by clinical examination is not an indication for testicular perfusion scintigraphy. This diagnostic procedure is, however, valuable if the clinical findings are equivocal and, especially, if a conservative treatment is planned. The method of and the results obtained with testicular scintigraphy in the differential diagnosis of acute scrotal pain are briefly described in this article. (orig.)

  1. Malignant Transformation Six Months after Removal of Intracranial Epidermoid Cyst: A Case Report

    Directory of Open Access Journals (Sweden)

    Fayçal Lakhdar

    2011-01-01

    Full Text Available Intracranial epidermoid cysts are uncommon benign tumors of developmental origin; malignant transformation of benign epidermoid cysts is rare, and their prognosis remains poor. We report a case of squamous cell carcinoma arising in the cerebellopontine angle. A 52-year-old man presented with left facial paralysis and cerebellar ataxia. He had undergone total removal of a benign epidermoid cyst six months previously. Postoperative magnetic resonance imaging of the brain revealed a heterogeneous and cystic lesion in the left cerebellopontine angle with hydrocephalus. The cyst wall was enhanced by gadolinium. He underwent ventricle-peritoneal shunt and removal again; the histopathological examination revealed a squamous cell carcinoma possibly arising from an underlying epidermoid cyst. This entity is being reported for its rarity. The presence of contrast enhancement at the site of an epidermoid cyst combined with an acute, progressive neurological deficit should alert the neurosurgeon to the possibility of a malignant transformation.

    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

    An epidermoid tumor inside the Meckel's cave is rare. The symptoms caused by this tumor include trigeminal neuralgia, facial hypesthesia and paresis of the 3rd, 4th and 6th nerves. A case of epidermoid tumor inside Meckel's cave was presented. A 54-year-old female who had complained of 3rd nerve palsy with right facial hypesthesia since 3 years before was referred to our clinic. Magnetic resonance imaging (MRI) showed the tumor at Meckel's cave. The tumor removal was performed using the orbito-zygomatic approach. To avoid injury of the internal carotid artery and nerves inside the cavernous sinus, removal of the tumor inside the capsule was carried out leaving the capsule. Postoperatively, the tumor removal was confirmed by MRI and improvement of the 3rd and the 5th nerve palsy was obtained three months after surgery. This case suggests that the capsule of the tumor inside the Meckel's cave should be allowed to remain to avoid injury of the adjacent 4th, 5th and 6th nerves and of the internal carotid artery.

    Intraosseous epidermoid cysts are exceedingly rare. Known as pseudotumors, not true neoplasms, intraosseous epidermoid cysts usually involve the phalanges, the skull, and the toes. Intraosseous epidermoid cysts typically present as destructive osteolytic lesions on X-ray, mimicking malignant bone tumors. Here, we present two cases of an intraosseous epidermoid cyst in the distal phalanx treated with curettage and synthetic bone graft, followed by a review of the relevant literature. In both cases, the patient presented with a painful enlargement of the fingertip following a minor trauma. Magnetic resonance imaging demonstrated lesions involving the distal phalanx that had a low signal on T1-weighted imaging (WI) and a high intensity on T2-WI. In both cases, the lesions were not enhanced by gadolinium. Good remodeling and functional recoveries were obtained. For physically active patients with substantial bone defects, synthetic bone graft may be recommended.

    This case report describes three brachycephalic dogs with intranasal epidermoid cysts that were causing additional upper airway obstruction. Although epidermoid cysts have been described in several locations in dogs, to the authors' knowledge intranasal epidermoid cysts have not been previously reported. All dogs had mucopurulent to haemorrhagic nasal discharge. Magnetic resonance imaging of the head revealed the presence of unilateral or bilateral intranasal cystic lesions obstructing the nasal cavities partially or completely, with atrophy of the ipsilateral nasal turbinates. The cystic lesions were surgically excised in all dogs using a modified lateral alveolar mucosal approach to the affected nasal cavity. Aerobic, anaerobic and fungal culture of the cystic contents were negative and histology of the excised tissue was consistent with a benign intranasal epidermoid cyst in each dog. Upper airway obstruction was clinically improved in two dogs.

    INTRODUCTION: Epidermoid and dermoid cysts of the central nervous system are usually developmental, benign tumors that arise when retained ectodermal implants are trapped by two fusing ectodermal surfaces. Together they compromise 1 - 1.5% of all brain tumors. Epidermoid cysts consist solely of layers of stratified squamous epithelium and localize more laterally (lateral sulcus, cerebellopontine angle (CP-angle)). Dermoid cysts also include dermal appendage organs (hair follicles and sebaceou...

  2. Testicular torsion: Case report

    Memik Ö et al.

    2012-02-01

    Full Text Available Testicular torsion represents a real emergency among genitourinary disorders. A delay in diagnosis may lead to orchiectomy. A six-year old male patient had abdominal pain with scrotal tenderness and swelling lasting two days. The patient attended the emergency service as his symptoms worsened. Physical examination revealed mild abdominal tenderness, left scrotal hyperemia and edema. Left testicle was also edematous and tender. Doppler ultrasonograpy demonstrated no vascular supply for the left testicle. Surgical exploration revealed a dark necrotic left testicle and no tissue vascularisation on a parenchymal incision. Therefore a left orchiectomy was performed upon the consideration of longer than two days of history. A probability of testicular torsion should be considered in the evaluation of acute abdomen for children of any age.

    One-hundred thirty-seven patients with a history or clinical evidence of cryptorchidism and testicular germinal tumor were treated at our hospital from 1934 to 1976. Cryptorchidism was corrected ipsilaterally or contralaterally in 93 patients with intrascrotal testis cancer when they were from 2 to 42 years old, either spontaneously (24 patients), by orchiopexy (58 patients), or by hormonal therapy (11 patients). Forty-four cryptorchid patients (uncorrected cases) had either ipsilateral inguinal (24 patients), or abdominal (14 patients), or contralateral intrascrotal tumors (six patients). Tumor histologic types on orchiectomy were pure seminoma in 56 patients, embryonal carcinoma in 41, teratocarcinoma in 37, and pure choriocarcinoma in 3. The five-year survival rates were similar in the corrected (61%) and uncorrected (63%) cases, and they were higher in patients with pure seminoma (79%) than in patients with germinal carcinomas (50%). The majority (64 of 80) of five-year survivors received regional lymphatic irradiation in 41 patients with pure seminoma and/or systemic chemotherapy in 23 patients with other germinomas. Since the testicular tumors that developed despite correction of the cryptorchid state were predominantly (72%) germinal carcinomas, unilateral cryptorchidism, which usually is associated with testicular atrophy, should be treated by orchiectomy instead of orchiopexy to prevent ipsilateral carcinogenesis. Cryptorchid patients with testicles that descended late should be observed periodically, especially after the 20-year latent period, for early detection of cancer.

    About 100 million women are estimated to be circumcised globally. Various rates of complications have been encountered, especially after circumcision, such as bleeding, infection, shock, menstrual irregularity, difficulty in urination or common urinary tract infections, inguinal pain, difficulty in sexual intercourse, and genital circumcision scar especially at the vulvar region, and cystic or solid character mass in short and long term. Furthermore, the maternal-fetal morbidity and mortality increase due to bleeding and fistula, which develop after prolonged labor, travail, and difficult labors. Our aim in this paper was to discuss a 42-year-old multiparous female case who had undergone type 2 radical genital mutilation (circumcision) when she was 7 years of age, along with the literature, which has been evaluated for the gradually growing mass at the left inguinal canal region in the last 10 years and diagnosed as epidermoid inclusion cyst developing secondary to postcircumcision surgical ground trauma, since there was no other case found in the literature search that had been circumcised at such an early age and developing after circumcision at such advanced age, and, therefore, this is suggested to be the first case on this subject.

    Full Text Available Testicular feminization syndrome is a form of pseudohermaphroditism where phenotypic female has male gonads and is genotypically male. Androgen insensitivity syndrome (AIS, also known as testicular feminization, encompasses a wide range of phenotypes that are caused by numerous different mutations in the androgen receptor gene. AIS is an X-linked recessive disorder that is classified as complete, partial based on the phenotypic presentation. The clinical findings include a female type of external genitalia, 46-XY karyotype, absence of Mullerian structures, presence of Wolffian structures to various degrees, and normal to high testosterone and gonadotropin levels. The syndrome is illustrated by a 24-year-old phenotypic female who presented with a primary amenorrhea, female-type external genitalia, an absent uterus and ovaries, and bilateral testes at the level of the internal inguinal ring. Management includes counseling, gonadectomy to prevent primary malignancy in undescended gonad, and hormone replacement. The karyotyping of family members is advocated because of known familial tendencies.

    2016-01-01

    Full Text Available Thymic epidermoid cysts are an extremely rare entity. These arise from epidermal cells that migrate to the thymus. The radiologic diagnosis of this rare lesion is challenging. We describe a case of an otherwise healthy 35-year-old woman who presented with an acute onset of chest pain and shortness of breath. She was found to have an anterior mediastinal mass. The imaging findings were, however, not characteristic for any single diagnostic entity. Since the imaging was inconclusive, surgical resection was performed for definitive diagnosis. The mass was found to be a thymic epidermoid cyst. This case underlines the significance for radiologists to be aware that epidermoid cysts can occur in the thymus and should be considered in the differential diagnosis for a heterogeneous anterior mediastinal mass.

    A case of epidermoid tumor in the left cerebellopontine angle cistern is reported in a 43-year-old woman with left trigeminal neuralgia. Plain CT scan revealed a low density area at the left cerebellopontine angle and left ambient cisterns, which could not be differentiated from their enlargement. Metrizamide CT cisternography showed an irregular, high density pattern in the low density filling defect which was extending into the suprasellar and interpeduncular cisterns. The developmental mechanism of this specific finding in the metrizamide CT cisternography was discussed on the basis of morphological characteristics of epidermoid tumor.

Presented here is a case of crossed ectopia of the right testis, treated by extraperitoneal transposition of the gonad and right orchiopexy. Embriology and surgical findings suggest that CTE is a common consequence of many unclear ethiologic factors, specially mechanical ones, and can be associated with Muller duct persistence. Review of literature suggests a classification of CTE into 3 types: I - associated with inguinal hernia alone; II - associated with persistent mullerian remnants; III - associated with other anomalies without mullerian remnants. Treatment includes transeptal orchiopexy or extraperitoneal transposition of the testis, research for mullerian remnants and other anomalies, and long term postoperative follow-up, due to the risk of becoming malignant.

    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.

We made the diagnosis of epidermoid cyst, giant comedone and leech bite on the basis of the constellation of clinical features. The patient was treated with oral ciprofloxacin at a dose of 2 g daily, and 2% topical erythromycin solution. Despite improvement, the evidence of cystic lesions persisted. There was no history of similar lesions in any other family member. There was no history of trauma. The patient was not using any topical or systemic medication. Two weeks before his visit, he had a history of leech therapy under the supervision of a general practitioner. His medical history was significant for leech therapy of the lesions, five days previously. He was followed up for another two weeks and after disappearance of the inflammation, with the patient under local anesthesia, the well-circumscribed mass was completely evacuated with a sharp curette and comedone extractor. The patient was subsequently lost to follow-up. Conclusion: Considering the efficacy of leeches, it would be favorable to breed a germ-free leech. In Iran, the use of the leeches in surgery, in recent years, has been infrequent. It appears that the positive effects of this ancient remedy may now be explained through scientific methods, promising potentially even more uses of this admirable creature in medicine.

    Full Text Available Objetivo. Evaluar el efecto de la desnutrición en la inducción de la giardiosis con diferentes concentraciones de quistes de Giardia lamblia utilizando como modelo animal ratas Sprague-Dawley. Material y métodos. Es un estudio experimental efectuado entre 1995 y 1999, en el Centro de Investigación en Alimentación y Desarrollo, de la ciudad de Hermosillo, estado de Sonora, México, y cuya muestra estuvo integrada por dos grupos de 6 a 8 unidades experimentales, las cuales recibieron dos tipos de dieta y cinco tratamientos con diferente concentración de inóculo de quistes de Giardia lamblia. Durante la fase experimental se monitoreó la excreción de quistes, ganancia de peso, consumo de alimento, análisis del contenido intestinal y daños macro y microscópicos en mucosa intestinal. El tratamiento estadístico de los datos consistió en análisis de varianza, y de residuales cuando fue necesario. Resultados. En los animales alimentados con una dieta que cubre sus requerimientos nutricionales (DN se observó que es posible provocar la infección con 60 quistes, mientras que en los animales desnutridos (dieta DLN la concentración que se requiere es de únicamente seis quistes para establecer daños a nivel de mucosa intestinal. Conclusiones. La ganancia de peso monitoreada durante los 10 días de ensayo no resultó ser un buen indicador de la infección por Giardia lamblia. El porcentaje de infección depende de la concentración de quistes inoculados y del estado de nutrición de los animales evaluados.

    An analysis of 125 patients with a history or clinical evidence of cryptorchidism and testicular germinal tumor treated at our hospital from 1934 to 1975 is presented. Cryptorchidism was corrected ipsilaterally or contralaterally in 83 patients with intrascrotal testis cancer when they were from 4 to 42 years old, either spontaneously (21 patients), by orchiopexy (51 patients) or by hormonal therapy (11 patients). Forty-two cryptorchid patients (uncorrected cases) presented with either ipsilateral inguinal (24 patients), abdominal (14 patients) or contralateral intrascrotal tumors (4 patients). Tumor histologic types on orchiectomy were pure seminoma in 54 patients, embryonal carcinoma in 35, teratocarcinoma in 33 and pure choriocarcinoma in 3. The 5-year survival rates were 60 per cent for the corrected cases and 63 per cent for the uncorrected cases according to cryptorchid state, and they were 78 per cent in patients with pure seminoma and 48 per cent in patients with other germinomas according to histologic type. The majority (58 of 73) of 5-year survivors received regional lymphatic irradiation, in 39 patients with pure seminoma, and/or systemic chemotherapy, in 19 patients with germinal carcinomas, with or without regional lymphadenectomy.

    Testicular biopsy was considered the cornerstone of male infertility diagnosis for many years in men with unexplained infertility and azoospermia.Recent guidelines for male infertility have limited the indications for a diagnostic testicular biopsy to the confirmation ofobstructive azoospermia in men with normal size testes and normal reproductive hormones.Nowadays,testicular biopsies are mainly performed for sperm harvesting in men with non-obstructive azoospermia,to be used for intracytoplasmic sperm injection.Testicular biopsy is also performed in men with risk factors for testicular malignancy.In a subgroup of infertile men,there is an increased risk for carcinoma in situ of the testis,especially in men with a history of cryptorchidism and testicular malignancy and in men with testicular atrophy.Ultrasonographic abnormalities,such as testicular microlithiasis,inhomogeneous parenchyma and lesions of the testes,further increase the risk of carcinoma in situ (CIS) in these men.For an accurate histological classification,proper tissue handling,fixation,preparation of the specimen and evaluation are needed.A standardized approach to testicular biopsy is recommended.In addition,approaches to the detection of CIS of the testis testicular immunohistochemistry are mandatory.In this mini-review,we describe the current indications for testicular biopsies in the diagnosis and management of male infertility.

    1989-12-01

    Lesions of Meckel's cave are extremely uncommon and difficult to diagnose. The symptoms and signs are variable, and the lesions may not appear on routine roentgenographic or computed tomographic examination. A patient with a small epidermoid tumor of Meckel's cave that was diagnosed by magnetic resonance imaging is herein reported. The epidermoid appeared as a low-intensity mass on the T1-weighted image and as a high-intensity mass on the T2-weighted image. Coronal sections defined the anatomic relationship to the trigeminal nerve. Preoperative recordings of the trigeminal sensory evoked response may be predictive of postoperative recovery of neurological deficits. Furthermore, intraoperative recording was extremely useful in avoiding inadvertent neurological injury. Review of the literature confirms the rarity of this lesion and the usefulness of magnetic resonance imaging in diagnosing it, although based on a limited number of cases.

    2016-01-01

    Gardner syndrome is known as a variant of familial adenomatous polyposis. This syndrome is characterized by multiple intestinal polyposes, osteomas, and epidermoid cysts. In addition, dental abnormalities include an increased frequency of multiple odontomas, as well as supernumerary and impacted teeth. The authors report the case of a 7-year-old male patient with Gardner syndrome. Radiographic findings revealed multiple osteomas in both sides of the maxilla, multiple diffuse enostoses in both jaws, and a complex odontoma in the left mandibular body. Two years later, multiple epidermoid cysts on the scalp were found. Since this patient was suspected to have Gardner syndrome, the authors recommended gastrointestinal endoscopy to check for intestinal polyposis. Gastrointestinal endoscopic examination revealed multiple polyposes in the upper gastrointestinal tract and fundus of the stomach. As a result, the final diagnosis was Gardner syndrome.

    A 27-year-old woman presented with headache and occasional numbness over her right face. Computed tomography revealed a hypodense mass in the middle cranial fossa and another adjacent hyperdense mass in the posterior fossa with erosion of the right petrous apex. Magnetic resonance imaging revealed the lesion in the middle cranial fossa as iso- to hypointense on T(1)-weighted and hyperintense on T(2)-weighted imaging, with peripheral enhancement after gadolinium administration, and the adjacent lesion in the posterior fossa as hyperintense on T(1)-weighted and hypointense on T(2)-weighted imaging. During surgery, these lesions mimicking two adjacent distinct tumors were revealed to connect through Meckel's cave. The hypodense lesion in the middle cranial fossa consisted of pearly-like solid contents, and the hyperdense lesion in the posterior cranial fossa consisted of viscid dark-green materials. The tumors were gross totally resected with endoscopic assistance. Histological examination confirmed that the tumor was an epidermoid cyst. The present case cyst indicates that although the diffusion-weighted imaging sequence is useful for detection of intracranial epidermoid cysts, epidermoid cysts including viscous materials with unusual radiological findings could complicate the preoperative diagnosis.

    Full Text Available Cystic disease of the spleen is not frequently encountered in surgical practice. It is broadly classified as parasitic and non-parasitic, the latter being a rare entity. In this case report, an epidermoid cyst of spleen led to acute abdomen in young age pregnant woman is presented.A 26-year-old woman with 15 weeks gestational age second pregnancy referred to emergency ward with left upper quadrant pain and tenderness that ultra sonography revealed large cyst (100х110mm with internal echo in spleen in favor of hydatic cyst or abscess. The patient was managed medically for one week but developed her abdominal pain, epigastric fullness, anorexia and fever. New sonography was done for her and large cyst was detected in spleen (120х110mm. She had severe pain accompanied with anorexia and vomiting. Fetus was normal in sonography. Exploratory laprotomy with splenectomy was performed. Splenomegaly (200х130х90mm with a cyst without any adhesion and inflammation was detected. Histopathology examination showed epidermoid cyst of spleen. (140х10х90mm. Though splenic epidermoid cyst is an uncommon entity, it should be considered in the differential diagnosis of an abdominal mass in a young individual. An attempt should be made to preserve the spleen provided there is adequate parenchyma otherwise splenectomy is the rule.

    Directory of Open Access Journals (Sweden)

    Sudhansu Sekhar Mishra

    2015-01-01

    Full Text Available Spinal epidermoid cyst, congenital or acquired, is mainly congenital associated with spinal dysraphism, rarely in isolation. Intramedullary epidermoid cysts (IECs are rare with less than 60 cases reported so far; isolated variety (i.e., without spinal dysraphism is still rarer. Complete microsurgical excision is the dictum of surgical treatment. A 14-year-old boy presented with 4-month history of upper backache accompanied with progressive descending paresthesia with paraparesis with early bladder and bowel involvement. His condition deteriorated rapidly making him bedridden. Neurological examination revealed upper thoracic myeloradiculopathy probably of neoplastic origin with sensory localization to D5 spinal level. Digital X-ray revealed no feature suggestive of spinal dysraphism. Contrast magnetic resonance imaging (MRI characteristics clinched the presumptive diagnosis. Near-total microsurgical excision was done leaving behind a small part of the calcified capsule densely adhered to cord. Histopathological features were confirmative of an epidermoid cyst. Postoperatively, he improved significantly with a gain of motor power sufficient to walk without support within a span of 6 months. Spinal IECs, without any specific clinical presentation, are often diagnosed based upon intraoperative and histopathological findings, however early diagnosis is possible on complete MRI valuation. Complete microsurgical excision, resulting in cessation of clinical progression and remission of symptoms, has to be limited to sub-total or near-total excision if cyst is adherent to cord or its confines.

  6. Testicular manifestation of a transformed mycosis fungoides

    Hendrik Borgmann

    2014-02-01

    Full Text Available Testicular neoplasms occur in more than 90% of cases, due to primary testicular germ cell tumors. Other entities are non germ cell tumors of the testis, testicular manifestation of lymphomas or metastases. International and interdisciplinary co-operation has led to the development of urological guidelines and to good therapeutic success for testicular neoplasms. The gold standard for treatment of a testicular neoplasm is the radical orchiectomy. However, for individual cases with suspected lymphoma, a treatment decision differing from the guidelines may be reasonable. We present the case of a 38-year-old man with testicular manifestation of a transformed mycosis fungoides, which is the most common form of cutaneous T-cell lymphoma.

    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.

A hypothesis was put forward that CIS originates from arrested fetal germ cells, thus testicular cancer is a developmental disease of germ-cell differentiation. This notion was supported by comparative studies of the gene expression at the protein and RNA level......, which demonstrated a close similarity of CIS to primordial germ cells and gonocytes with many features of embryonic stem cells. The arrest of germ-cell differentiation is thus the key first event, which may be followed by malignant transformation and overt germ-cell cancer in young adult age, usually......Testicular germ-cell tumors occur primarily in young individuals, and the tumors in this age group (seminomas or nonseminomas) are derived from a preinvasive precursor cell called carcinoma in situ (CIS) or intratubular germ-cell neoplasia.

    2012-01-01

    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.

Método: Se realizó un estudio retrospectivo de los pacientes con diagnóstico clínico, citológico y/o histológico de quiste tirogloso, branquial y dermoide, atendidos en el Hospital Universitario «Arnaldo Milián Castro», durante cinco años. Se calculó la sensibilidad, especificidad y seguridad del diagnóstico clínico y la biopsia por aspiración con aguja fina (FNAC para cada quiste. Resultado: La seguridad del diagnóstico clínico fue de 94,1%, 92,2% y 98% para los quistes tirogloso branquial y dermoide respectivamente. Encontramos mayor tendencia al error clínico en los quistes branquiales, donde las confusiones más frecuentes se presentan con linfoadenopatías inflamatorias. La seguridad de la biopsia por aspiración con aguja fina fue de 96,1% y 94,1% para los quistes tirogloso y branquial respectivamente. Conclusiones: El diagnóstico clínico no es suficiente en ocasiones, por lo que es preciso recurrir a medios diagnósticos complementarios, como la biopsia por aspiración con aguja fina; sin embargo esta prueba no es 100% segura.Objective: To determine the effectiveness of clinical and cytological diagnosis in congenital cysts located in head and neck.

La importancia de esta diferenciación radica en el tratamiento, que es ligeramente más agresivo en el FA y en el comportamiento biológico, ya que el FA puede derivar en un sarcoma ameloblástico, y el QF puede evolucionar hacia ameloblastoma y más raramente carcinoma mucoepidermoide.Abstract: Ameloblastic fibroma (AF is a mixed odontogenic tumor composed of mesenchymal tissue and odontogenic epithelium, accounting for 2% of all odontogenic tumors, while dentigerous or follicular cyst (FQ, second odontogenic cyst in frequency, is formed exclusivelly by soft conective tissue (mesenchyme. Nevertheless, hiperplastic fibrous sac may contain rests of odontogenic epithelium, showing a similar histologic pattern. The importance of an adequate differentiation lies in the treatment, which is slightly aggresive for AF, and regarding the biological behaviour of both lesions, since AF might become in an ameloblastic sarcoma, while over an FQ could develope an ameloblastoma or even a mucoepidermoid carcinoma.

    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.

    In this study, a case has been reported involving a 66-year old male who was admitted for scrotal pain on the right side with possible testicular involvement, but with no associated urinary disorder. At physical examination, the right testicle was found to have increased in volume: this was further confirmed by ultrasonography, but the findings were insufficient to exclude the hypothesis of testicular cancer. An exploratory orchidectomy by upper inguinal route was therefore carried out, and histopathological examination showed the destruction of testicular tissue by several granulomas, and caseous necrosis with giant cells. Antibacterial chemotherapy was administered after an i.v. urography found no evidence of abnormality or urinary disorder, thereby eliminating an active site of genitourinary tuberculosis. This case shows the importance of considering testicular tuberculosis in the differential diagnosis of testicular enlargement in a region where this disease is endemic, despite the absence of systemic pulmonary and urinary signs of tuberculosis.

La etiología no está aún determinada, pero existen tres teorías. Esta patología se observa en niños y adultos, predominantemente en mujeres. Pueden manifestarse anomalías en todo el sistema biliar, ya sea intra o extrahepático. Se clasifica en 5 tipos. Antes, el abordaje de dichos quistes era la cistoentero anastomosis, pero ahora se recomienda realizar una escisión completa del quiste, para disminuir el riesgo de malignidad y desarrollo de colangitis o pancreatitis recurrente. Aquí se presenta el caso de una mujer de 21 años con dolor abdominal, ictericia y una masa en el hipocondrío derecho, secundario a dicha patología, que fue sometida a una resección quirúrgica con anastomosis primaria. La evaluación anatomopatológica demostró una estructura quística de aspecto similar a una vesícula biliar, congestiva y pardusca, con inflamación crónica leve. Tuvo un postoperatorio satisfactorio y egresó con tratamiento antibiótico.

    Oral leukoplakia is a relatively common, painless disorder of the oral mucosa. It predominantly affects middle-aged to elderly men and has a strong association with tobacco smoking and alcohol intake. Concomitant histological findings of hyperorthokeratosis and a well-developed granular cell layer, termed orthokeratotic dysplasia, are often associated with oral squamous cell carcinoma. In contrast, analogous lesions within the esophagus, termed esophageal epidermoid metaplasia, are rarely encountered and poorly described in the literature. To better characterize the clinicopathological features of this entity, we have collected 25 cases from 18 patients. Patients ranged in age from 37 to 81 years (mean, 61.5 years), with a slight female predominance (10/18, 56%). On presentation, a majority of patients complained of dysphagia (10/18, 56%). Past medical history was significant for tobacco smoking or long history of second-hand smoke in 11 (61%) patients and alcohol intake in 7 (39%) patients. Seventeen (94%) patients with esophageal epidermoid metaplasia were located within the middle-to-distal esophagus. Histologically, all cases were sharply demarcated and characterized by epithelial hyperplasia, a thickened basal layer, acanthotic midzone, a prominent granular cell layer, and superficial hyperorthokeratosis. Adjacent high-grade squamous dysplasia and/or squamous cell carcinoma were seen in 3 out of 18 (17%) patients. Follow-up information was available for 13 out of 18 (72%) patients and ranged from 2 to 8.3 years (mean, 2.3 years). Seven of the 13 (54%) patients had persistent disease; however, none of them developed squamous dysplasia or squamous cell carcinoma. In an effort to assess the incidence of esophageal epidermoid metaplasia, 198 consecutive esophageal biopsies were prospectively surveyed over a 6-month period at three academic institutions. No cases were identified within this time frame. In summary, esophageal epidermoid metaplasia is a rare

    We report the case of a 32-year-old man with an epidermoid tumor of the fourth ventricle. About 14 years later, he showed a tumor recurrence which was removed. After this procedure the patient complained of presyncopal and syncopal crisis while attempting to stand or walk. On examination, severe orthostatic hypotension was confirmed and autonomic tests were abnormal. The brain MRI showed a tetraventricular hydrocephalus predominating in the fourth ventricle. A ventriculo-peritoneal shunt was performed, and after surgery the orthostatic intolerance improved. We believe that hydrocephalus has probably been a contributory factor to orthostatic hypotension, and suggest expanding testing for dysautonomia in patients with hydrocephalus.

    Phellinus linteus (Berkeley & Curtis) Teng, a well-known fungus of the genus Phellinus in the family of Hymenochaetaceae, is being increasingly used to treat a wide variety of disease processes such as oral ulcer, gastroenteric disorder, inflammation, lymphatic disease, and various cancers. However, the mechanism underlying its anti-oral cancer effect is poorly understood. In the present study, we prepared the ethanol extract of Phellinus linteus as a crude drug, and then obtained the active component hispolon by bioassay-guided isolation. Hispolon showed a dose-dependent inhibition of human epidermoid KB cell proliferation with IC50 of 4.62+/-0.16 microg/ml. Furthermore, it was revealed that hispolon could induce human epidermoid KB cell apoptosis with the characteristic of a DNA ladder, and with a significant increase of sub-G1. This process was accompanied by the collapse of mitochondrial membrane potential, the release of cytochrome c and the activation of Caspase-3. These results demonstrated that hispolon induced the death of KB cells through a mitochondria mediated apoptotic pathway. We propose that Phellinus linteus and its effective components could be used as an anti-oral cancer drug for future studies.

    Vascular occlusions are the clinical indicators of sickle cell disease and in urology they can lead to papillary necrosis, renal infarction or priapism. Segmental testicular infarction in patients with sickle cell disease is a rare event and only a few cases have been reported. We present a 25-year-old man with right testicular pain increasing over 3 days and sickle cell disease. Ultrasound of the right scrotum presented an inhomogeneous, mainly hypoechegenic mass with a hyperechogenic margin and no sign of blood flow.

    Testicular cancer is the most common malignancy in men aged 15-35 years and predominantly occurs at a time in a man\\'s life when important decisions about marriage, starting a family and a professional career are being made. While treatments for testicular cancer are very successful, they can have a major impact on the person\\'s sexuality and sense of self. The focus of this article is on exploring the impact of cancer treatments for testicular cancer on men\\'s sexuality and how nurses can respond to their concerns in a sensitive and informed manner.

    Despite the prevalence of testicular cancer among men 15-39 years of age, little has been done to increase awareness of this disease or educate males about its prevention. To fill this gap, the Standard Model of Health Communication was incorporated to design and implement a comprehensive testicular cancer campaign among male college students. To test the effectiveness of these messages, college students (N = 220) completed measures before and after the campaign. In addition, the authors obtained a control group of male college students (N = 52) who were not exposed to the messages. Survey items assessed awareness of testicular cancer and behaviors related to testicular cancer. Participants' knowledge of testicular cancer and likelihood of conducting a testicular self-exam increased significantly after being exposed to the campaign information. Men who were exposed to testicular cancer messages were more knowledgeable about testicular cancer and were more likely to conduct testicular self-examinations than were men in the control group.

    Diabetes was induced in adult male albino rats by a single intravenous injection of streptozotocin (75 mg/kg body weight). The diabetes was allowed to stabilize for at least 15 days, whereafter the testicular and seminal vesicle histology was studied at various time intervals. Reduction in testis weights and tubule diameters was significant after 2 weeks of diabetes. The changes in seminiferous tubules ranged from premature sloughing of epithelium to total cessation of spermatogenesis. The testicular histology of diabetic animals frequently greatly simulated the situation described following hypophysectomy. By subjective visual assessment the number of Leydig cells was found to be normal or reduced in all of the diabetic animals. Diabetes was also demonstrated to induce seminal vesicle atrophy, which did not show any correlation with the degree of testicular lesions. The possible etiology of testicular damage in diabetic animals is discussed.

    Full Text Available Transverse testicular ectopia is an extremely rare anomaly, characterized by migration of one testis towards the opposite inguinal canal, usually associated with inguinal hernia. Spermatic cord of the ectopic testis originates from the appropriate side. In most reported cases, the accurate diagnosis has not been made before surgery. This is a case report of transverse testicular ectopia in eleven-year-old boy who had undergone an operation for the left inguinal hernia in age often months. At the time of herniorrhaphy, the right testis was absent. Ten years later, during re-operation of the left inguinal hernia, both testis were found in left inguinal canal and easily brought down sequentially through the left groin into the scrotum. The right testis was fixed in the left hemiscrotum, due to shorter funicular elements, and the left was trans-septally moved to the right hemiscrotum (a modified Ombrédanne operation. Ultrasonography and voiding cystoureterography showed no associated genitourinary anomalies and no Mülerian duct remnants. The rupture of gubernaculum and dysfunction of the genito-femoral nerve could explain the etiology of crossed testis ectopia. Although ectopic testis could be localized preoperatively by ultrasonography, CT, MRI, arteriography and venography, correct diagnosis was made intraoperatively in the majority of cases. Treatment modalities include laparoscopic and surgical procedures. Atrophie testis should be removed. If testes are fused, they have to be brought into one hemiscrotum. In cases where testes are completely separated with individual funicular elements and vas deferens, an ipsilateral or contralateral orchiopexy should be performed depending on the length of funicular elements.

    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.

    Testicular tumours are rare neoplasms, which most commonly affects men aged 25 to 35 years. Among young adult males it is the most common cause of testicular swelling. In recent decades, the number of cases of testicular tumours has greatly increased. The most significant predisposing factors are cryptorchidism and some endocrine disorders, especially increased levels of gonadotropins and female sex hormones. Testicular trauma, inguinal hernia, extreme values of body mass index (BMI), high-calorie diet rich in dairy products as well as high social status are also regarded as risk factors. Furthermore, some chromosomal abnormalities like increased number of chromosomes 7, 8. 12, 21 and X, loss of chromosomes 4, 5, 11, 13, 18, or Y, mutation in the gene Xq27; as well as multiplied copy of the gene i(12p) are associated with tumor development. It has been proven that high testosterone levels and regular physical activity may prevent testicular tumours. Since one of the first sign the lesion is often a lump or swelling of the testis and the appearance of abnormal structure in the scrotum routine testicular self-examination seems to be important in early detection. In all suspected cases an immediate ultrasound examination of both testicles is highly recommended. It is also advised to conduct a computerized tomography (CT) and a positron emission tomography (PET) scan for staging of the tumor to select the best mode of treatment.

    Infertility induced by anti-cancer treatments pose a major concern for cancer survivors. Doxorubicin (DXR) has been previously shown to exert toxic effects on the testicular germinal epithelium. Based upon the cardioprotective traits of dexrazoxane (DEX), we studied its potential effect in reducing DXR-induced testicular toxicity. Male mice were injected with 5  mg/kg DXR, 100  mg/kg DEX, combination of both or saline (control) and sacrificed either 1, 3 or 6 months later. Testes were excised and further processed. Glutathione and apoptosis assays were performed to determine oxidative stress. Immunohistochemistry and confocal microscopy were used to study the effects of the drugs on testicular histology and on spermatogonial reserve. DXR and the combined treatment induced a striking decline in testicular weight. DEX prevented DXR-induced oxidative stress, but enhanced DXR-induced apoptosis within the testes. Furthermore, the combined treatment depleted the spermatogonial reserve after 1 month, with impaired recovery at 3 and 6 months post-treatment. This resulted in compromised sperm parameters, testicular and epididymal weights as well as significantly reduced sperm motility, all of which were more severe than those observed in DXR-treated mice. The activity of DEX in the testis may differ from its activity in cardiomyocytes. Adding DEX to DXR exacerbates DXR-induced testicular toxicity.

    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...

    The development of an epidermoid cyst in an intrapancreatic accessory spleen is an extremely rare lesion, with only 17 cases being reported in the English literature. All such cases were located in the pancreatic tail, some of which showed carbohydrate antigen 19-9 (CA19-9) immunoreactivity in the lining of the epithelium. A few of them indicated an elevation of the serum CA19-9 level. Here we report three cases of an epidermoid cyst in an intrapancreatic accessory spleen. Cases 1 and 2 were 57-year-old and 70-year-old women, while case 3 was a 37-year-old man. All three cases were asymptomatic. Serum CA19-9 levels showed within normal limits (case 1), slightly elevated (case 2), and clearly elevated (case 3). They underwent a distal pancreatectomy with splenectomy (cases 1 and 2) and without splenectomy (case 3). Grossly, the surgical specimen was a well-demarcated, multiple (case 1) or solitary (cases 2 and 3) cystic mass in the pancreatic tail. A high level of fluid CA 19-9 was detected in case 1. Microscopically, the cystic walls were lined with squamous and cuboidal epithelium, which were surrounded by normal splenic tissue and hyalinized fibrous tissue. The lining squamous epithelium was revealed as nonkeratinizing (Cases 1 and 2) or keratinizing (Case 3). Immunohistochemically, CA19-9 was positive in the monolayer and surface layer of the cuboidal epithelium, but negative for the keratinizing squamous epithelium. As for the histogenesis, it is suggested that the cystic lining of the epithelium may derive from the pancreatic duct which protrudes into the accessory spleen.

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

    Directory of Open Access Journals (Sweden)

    Henry A. A. Ugboma

    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.

Otras causas son infrecuentes. Los quistes del cordón espermático son poco frecuentes, pero aún más su ubicación intraabdominal, su tamaño habitual es insuficiente para producir distensión. El paciente presentado en este caso es un varón con criptorquidia bilateral admitido por distensión abdominal, interpretada inicialmente como síndrome ascítico edematoso.

En la exploración quirúrgica se diagnosticó un quiste gigante del cordón espermático de ubicación abdominal.Abdominal distention is a frequent symptom, being often the initial presentation of systemic diseases or gastrointestinal disorders. Other causes are uncommon. Spermatic cord cysts are infrequent, abdominal location is even rarer, and the size of the cysts is usually not enough to produce abdominal distention. In our case a man with bilateral cryptorchidism was admitted with abdominal distention and edema of the lower extremities initially interpreted as ascitic-edematous syndrome. Ultrasonography interpreted abdominal distention as septate ascites, computed tomography as a giant cyst. Exploratory surgery showed a giant spermatic cord cyst in the left spermatic cord.

    2008-01-01

    Aim: To evaluate the relationship between testicular function and testicular volume measured by using Prader orchidometry and ultrasonography (US) to determine the critical testicular volume indicating normal testicular func-tion by each method. Methods: Total testicular volume (right plus left testicular volume) was measured in 794 testes in 397 men with infertility (mean age, 35.6 years) using a Prader orchidometer and also by ultrasonography.Ultrasonographic testicular volumes were calculated as length×width×height×0.71. To evaluate volume-function relationships, patients were divided into 10 groups representing 5-mL increments of total testicular volume by each method from below 10 mL to 50 mL or more. Results: Mean total testicular volume based on Prader orchidometry and US were 36.8 mL and 26.3 mL, respectively. Semen volume, sperm density, total sperm count, total motile sperm count, and serum FSH, LH, and testosterone all correlated significantly with total testicular volume measured by either method. Mean sperm density was in the oligozoospermic range in patients with total testicular volume below 35 mL by orchidometry or below 20 mL by ultrasonography. Mean total sperm count was subnormal in patients with total testicular volume below 30 mL by orchidometry or under 20 mL by ultrasonography. Conclusion: Testicular volume measured by either ultrasonography or Prader orchidometry correlated significantly with testicular function.However, critical total testicular volume indicating normal or nearly normal testicular function was 30 mL to 35 mL using Prader orchidometer and 20 mL using ultrasonography. Prader orchidometry morphometrically and function-ally overestimated the testicular volume in comparison to US.

Antes, el abordaje de dichos quistes era la cistoentero anastomosis, pero ahora se recomienda realizar una escisión completa del quiste, para disminuir el riesgo de malignidad y desarrollo de colangitis o pancreatitis recurrente. Aquí se presenta el caso de una mujer de 21 años con dolor abdominal, ictericia y una masa en el hipocondrío derecho, secundario a dicha patología, que fue sometida a una resección quirúrgica con anastomosis primaria. La evaluación anatomopatológica demostró una estructura quística de aspecto similar a una vesícula biliar, congestiva y pardusca, con inflamación crónica leve. Tuvo un postoperatorio satisfactorio y egresó con tratamiento antibiótico. El quiste coledociano debe considerarse en el diagnóstico diferencial de aquellos pacientes con dolor abdominal y masa en el cuadrante.Choledochal cyst is a dilatation of a component of the biliary tree and it may include both intra and extrahepatic sites. They are classified into five types, all of which are relatively rare. Previously, choledochal cysts were treated with biliaryenteric bypass procedures. The current recommendation is to attempt their complete excision to minimize the known risk of fecoming malignant and the development of recurrent cholangitis or pancreatitis that may occur in these patients. We present here the case of a 21 year old woman with abdominal pain and jaundice due to a type 1 choledochal cyst. The cyst was removed and patient did fine.

    Zika virus (ZIKV) is an emerging mosquito-borne flavivirus that has recently been found to cause fetal infection and neonatal abnormalities, including microcephaly and neurological dysfunction. ZIKV persists in the semen months after the acute viremic phase in humans. To further understand the consequences of ZIKV persistence in males, we infected Ifnar1−/− mice via subcutaneous injection of a pathogenic but nonlethal ZIKV strain. ZIKV replication persists within the testes even after clearance from the blood, with interstitial, testosterone-producing Leydig cells supporting virus replication. We found high levels of viral RNA and antigen within the epididymal lumen, where sperm is stored, and within surrounding epithelial cells. Unexpectedly, at 21 days post-infection, the testes of the ZIKV-infected mice were significantly smaller compared to those of mock-infected mice, indicating progressive testicular atrophy. ZIKV infection caused a reduction in serum testosterone, suggesting that male fertility can be affected. Our findings have important implications for nonvector-borne vertical transmission, as well as long-term potential reproductive deficiencies, in ZIKV-infected males. PMID:28261663

    Full Text Available Segmental (partial testicular infarction is a very rare condition of unknown cause in more than 70% of cases. Several predisposing conditions have been described, but to our knowledge, this is the first documented case and often overlooked complication occurring as a result of cysto-prostatectomy. It usually presents in an acute manner resembling testicular torsion or epididymo-orchitis and is confirmed using ultrasonography. In some cases, it may present insidiously with no pain and may be confused with a testicular tumor due to the hypo-echoic features on imaging. In unclear situations, Doppler sonography shows vascularity and a magnetic resonance scan can be useful to distinguish between the two conditions.

    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.

    To evaluate the eco graphic patters of testicular microlithiasis (TM) in paediatric age, its associations, clinical implications and how to manage them. We study four children between 11 and 13 years old with testicular microlithiasis. The echographic study is realized with a 7.5 Mhz linear probe. Two of the cases present bilateral microlithiasis. In five of the testicles, the presentation fits the pattern of classic testicular microlithiasis (CTM) ({>=} 5 echogenic foci per transducer field) and one testicle presents limited testicular microlithiasis (< 5 echogenic foci per transducer field). Distribution in the case of CTM is diffuse in two testes, peripheral in another two testicles and central in one of them. In one of the bilateral presentations, a biopsy of both testes is performed, observing intra tubular calcification in both. None of them has developed a tumor during the follow-up period, which ranges from nine months to four years. (Author) 21 refs.

    Objective To investigate effects of cryopreservation on changes of the ultrastructure of human testicular sperm and evaluate the efficacy of cryopreserving testicular tissue as a source of sperm for assisted reproduction.Methods Testicular biopsy tissues were obtained from infertile patients (n=12) with obstructive azoospermia and cryopreserved. Testicular sperm motility was observed after in vitro culture procedure. The ultrastructure of testicular sperm (n=6) was examined by transmission electron microscope.Results After cryopreservation, 10 biopsy tissues frozen revealed motile sperm, and 2samples showed non-motile sperm. Some testicular sperm in frozen-thawed group had normal morphology in fine structures. Sperm head in frozen-thawed tissue showed a proportion of nuclei with more electron-dense granules of chromatin. In a few frozen-thawed sperm heads, formation of vesicles and degeneration were observed.The frozen-thawed testicular sperm frequently showed swollen or/and ruptured of the plasma membrane and acrosome membranes.Conclusion Cryopreservation of testicular tissue is simple and efficacious for testicular sperm extraction. And the freezing-thawing procedure of testicular tissue causes damage to ultrastructural morphology of human testicular sperm.

    2014-12-01

    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.

    2013-01-01

    Patients with non-obstructive azoospermia (NOA) were once considered to be infertile with few treatment options due to the absence of sperm in the ejaculate.In the last two decades,the advent of intracytoplasmic sperm injection (ICSI),and the application of various testicular sperm retrieval techniques,including fine needle aspiration (FNA),conventional testicular sperm extraction (TESE) and microdissection testicular sperm extraction (micro-TESE) have revolutionized treatment in this group of men.Because most men with NOA will have isolated regions of spermatogenesis within the testis,studies have illustrated that sperm can be retrieved in most men with NOA,including Klinefelter's syndrome (KS),prior history of chemotherapy and cryptorchidism.Micro-TESE,when compared with conventional TESE has a higher sperm retrieval rate (SRR) with fewer postoperative complications and negative effects on testicular function.In this article,we will compare the efficacy of the different procedures of sperm extraction,discuss the medical treatment and the role of testosterone optimization in men with NOA and describe the micro-TESE surgical technique.Furthermore,we will update our overall experience to allow counseling on the prognosis of sperm retrieval for the specific subsets of NOA.

    Testicular function was investigated by testicular biopsy, testicular volume, testosterone and LH-RH test in 16 prepubertal boys with 15 cases of acute leukemia and one case of malignant lymphoma after chemotherapy and/or testicular irradiation. One of 2 cases who had infiltrated in testes received irradiation at onset. With another 2 cases, testis was resected at testicular relapse and irradiated on opposite side. All continued complete remission for 1-9 years after cessation of chemotherapy. Basal levels of serum testosterone, FSH and LH were normal in 13 cases of unirradiated group recently but spermatogonia in testicular biopsy specimen decreased on cessation of chemotherapy in 8 cases. Primary gonadal dysfunction was detected in 3 cases of irradiated group. And so testicular irradiation induced damage of tubular system and Leydig cell function. It is necessary to follow up about sexual maturation. (author).

    Identifying new chemotherapeutic agents with fewer side effects is a major concern for scientists today. Thymus caramanicus Jalas (Lamiaceae family) is one of the species of Thymus that grows wild in different regions of Iran. Traditionally, leaves of this plant are used in the treatment of diabetes, arthritis and cancer. Here was investigated the cytotoxic property of Thymus caramanicus essential oil and extract in human oral epidermoid carcinoma KB cells. Cell viability was measured by MTT and neutral red assays. The cells were exposed to different concentrations of essential oil (0.05-1 µL/mL) and extract (25-150 µg/mL) for 24 h. Doxorubicin was used as anticancer control drug. The data showed that the essential oil (IC50=0.44 µL/mL) and extract (IC50=105 µg/mL) induce potent cytotoxic property. Surprisingly, cytotoxic effects of essential oil and extract of this plant on KB cancer cells were greater than those on normal gingival HGF1-PI1 cell line. In addition, Thymus caramanicus could potentiate the effect of doxorubicin in sub-effective concentrations. The results of the present study indicate that essential oils and extracts of Thymus caramanicus have potential anti-proliferative property on KB cells and can be used as pharmaceutical case study for oral cancer treatments.

They represent between the 0,2 and 2 % of all the intracranial tumours and represent the 15 or 20 % of all the intraventricular masses. They become symptomatic during the adolescence or early adulthood and start normally with migraine or symptoms of intracranial hypertension causing obstructive hydrocephaly. We present the case of a teenager of 18 years of age with history of migraine after two years and the symptoms worsened in intensity and frequency including vomiting and bilateral paresthesia; the diagnosis was obstructive hydrocephaly with colloidal cyst of the third ventricle. An appropriate practice was adopted due to the uncertain diagnosis in order to avoid neurological damage and death. We discussed the main characteristics of the colloidal cyst, its clinical presentation and radiological characteristics and we performed.

Suponen del 0,2 al 2 % de todos los tumores intracraneales y representan del 15 al 20 % de todas las masas intraventriculares. Comienzan a ser sintomáticos en la adolescencia o edad adulta temprana, generalmente con manifestaciones de cefalea o síntomas de hipertensión intracraneal al provocar hidrocefalia obstructiva. Se presenta una adolescente de 18 años con historia de cefalea de 2 años de evolución, cuyos síntomas fueron empeorando en intensidad y frecuencia, acompañados de vómitos y parestesias bilaterales; se le diagnosticó hidrocefalia obstructiva con quiste coloide del tercer ventrículo. Ante la sospecha del diagnóstico se tomó una conducta adecuada, para evitar el deterioro neurológico y la muerte. Se discutieron las principales características del quiste coloide, su cuadro clínico y radiológico.

    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/disorders of sex differentiation and male fertility problems may be symptoms with varying penetration. In spite of their fetal origin, most of the TDS symptoms, including TGCC and poor semen quality, can only be diagnosed in adulthood. Data from a Danish-Finnish research collaboration strongly suggest that trends 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 problems may also be rising.

    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.

    Extramedullary myeloid cell tumors (EMCT) are localized collections of immature myeloid cells that occur outside of the bone marrow. Usually observed concurrently with bone marrow disease, EMCT also may occur in the absence of overt marrow leukemia. In this report, we describe an infant with a testicular mass that was identified as an EMCT after orchiectomy. Unlike the only previously reported case of infantile testicular chloroma, this patient did not exhibit bone marrow disease at diagnosis. Because systemic chemotherapy is considered to be superior to local control (surgery, radiation therapy), the patient was treated with intensively timed induction chemotherapy followed by 3 cycles of maintenance treatment (according to CCG protocol #2891) but no radiation therapy. The patient remains disease-free 18 months after diagnosis.

    During the past ten years, substantial progress has been made in the knowledge of the natural history of epidermoid carcinoma of the anal canal and of the response of the disease to radiotherapy alone or combined with chemotherapy. At the present time, the main problem in the management of this tumor concerns identification of the best modalities to achieve local control and preservation of anal function. From a series of 276 cases, followed for more than three years, the necessity for a careful pretreatment evaluation was stressed. This included a systematic search for pelvic metastatic lymph nodes by palpation and CT scan. All patients were treated initially by irradiation except those who underwent groin dissection for inguinal node metastasis or colostomy for complete anal obstruction. Three groups of patients have been identified: unresectable or disseminated tumors (33 cases), resectable tumors but not suitable for sphincter conservation (21 cases) treated by radiochemotherapy and delayed surgery, and resectable tumors suitable for sphincter conservation (222 cases) which were treated by a split-course regimen combining a short course of carefully planned external beam irradiation (19 days) followed by an iridium 192 implant after a two-month rest. In this group, which represents 80 percent of the whole series, 80 percent of patients have had their cancer controlled and 90 percent of controlled patients have retained normal anal function. The use of chemotherapy during the first days of irradiation is advisable in all cases to reinforce the efficacy of treatment and increase the chance of anal preservation. Results of the split-course regimen, combining external beam and interstitial irradiation, demonstrate a clear superiority over external beam irradiation alone, especially for large infiltrating tumors, which represent the majority of cases.

    Aim: To evaluate the value of magnetic resonance (MR) diffusion-weighted imaging (DWI) and apparent diffusion coefficients (ADC) maps in the diagnosis of intraparenchymal epidermoid cysts (ECs). Materials and methods: Six cases of histopathologically proven intraparenchymal ECs were studied. All patients were examined with conventional MR (T1WI, T2WI, contrast-enhanced T1WI) and DWI sequences. Along with the mean ADC values (mADC) of the ECs, the cerebrospinal fluid (CSF) and grey matter (GM) were measured. Qualitative and quantitative assessments, as well as MRI findings, were retrospectively analysed using a double blind method by three radiologists in consensus. Results: Four lesions were located in the cerebellum, among them, one was accompanied by an arachnoid cyst; one huge lesion crossed the parenchyma of the frontal and temporal lobes; the other was located in the left temporal lobe. Two lesions had a homogeneous CSF-like intensity on both T1WI and T2WI. The other four were of mixed-intensity on both T1WI and T2WI. All lesions were strikingly hyperintense on DWI, and iso- or slightly hypointense on ADC (relative to the brain). The mADCs of the ECs were significantly higher than that of GM, but significantly lower than that of CSF. Three cases (3/6) were accurately diagnosed using conventional MR sequences without DWI, but in the remaining three cases, correct diagnosis could only be made with help of DWI. Conclusion: DWI sequences can facilitate the diagnosis of intraparenchymal ECs, thus alerting surgeons of the risk of chemical meningitis at surgery. The MR findings of intraparenchymal ECs are basically as the same as those of extracerebral ECs, but the former is likely to have a mixed signal. The hyperintense signal of ECs on DWI is probably caused by the T2 shine-through effect in tumour tissue.

    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.

  1. Downregulation of Clusterin Expression in Human Testicular Seminoma

    2013-11-01

    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.

    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.

    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.

    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.

    2013-12-01

    Testicular microlithiasis (TM) is a rare benign condition with presence of multiple small microcalcifications in the seminiferous tubules. Though the aetiology is unknown, TM has been described in association with a variety of urological conditions. We report the clinico-pathological features of a 12-year-old male child who underwent orchidectomy for undescended testis. Histopathological examination of the excised testis showed multiple small intratubular calcifications without any evidence of testicular neoplasia. TM is an unusual phenomenon that should be kept in mind while evaluating testicular biopsies. Though it behaves in a benign manner in most of the cases, patients with positive family history of testicular cancer should be followed-up for testicular tumour.

    A 17-year-old man presented with right hydrocele because of an athletic injury. His scrotum was hit with a ball 2 months ago while playing baseball. He was diagnosed with post-traumatic hydrocele and underwent needle puncture at another hospital 1 month after the trauma. However, the hydrocele did not improve. Therefore, he was referred to our hospital for surgical treatment. For diagnosis of the traumatic hydrocele testis, a hydrocelectomy was scheduled. When we opened the tunica vaginalis, we realized that the tunica albuginea had been ruptured and the testicular parenchyma had gushed out. We tried to replace all the escaped testicular parenchyma into the tunica albuginea, but it was impossible. Therefore were moved some of the redundant testicular parenchyma, and replaced the remnants into the tunica albuginea. After the operation, right hydrocele and testicular atrophy did not occur. Traumatic testicular rupture complicated with hydrocele is rare.

  12. Role of US in testicular and scrotal trauma.

    2008-10-01

    High-frequency ultrasonography (US) with a linear-array transducer is the modality of choice for the initial evaluation of patients with acute scrotal pain after trauma. Testicular trauma is the third most common cause of acute scrotal pain. US is useful in the triage of patients for medical or surgical management because it reliably depicts tunica albuginea rupture, intra- and extratesticular hematomas, and testicular contusions. Color Doppler US allows direct evaluation of testicular perfusion and detection of uncommon conditions, such as testicular torsion, that may be associated with scrotal trauma. In addition, 10% of testicular tumors are found incidentally at US performed for the evaluation of trauma. If a conservative approach is adopted for the management of an intratesticular abnormality after trauma, follow-up US should be performed until the images show a complete resolution of the abnormality, so that a tumor will not be missed.

    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.

    Testicular torsion and detorsion are important clinical problems for infertile man and oxidative stress may have a role in this clinical situation. The aim of this study was to investigate the protective role of erdosteine, an antioxidant, on unilateral testicular reperfusion injury in rats. The rats were divided into four groups including seven rats in each group: control, torsion, torsion/detorsion and torsion/detorsion+erdosteine. Rats, except the sham operation group, were subjected to left unilateral torsion (720( composite function) rotation in the clockwise direction) without including the epididymis. The experiments were finished after sham operation time for control, 120 min torsion for torsion group and 120 min torsion and 240 min detorsion for torsion/detorsion groups. Bilateral orchiectomy was performed for all groups of rats. The ipsilateral and controlateral testis were divided into two pieces to analyse biochemical parameters and to investigate the light microscopic view. Malondialdehyde level of ipsilateral testis was increased in torsion and torsion/detorsion groups in comparison with the other groups (p Erdosteine treatment ameliorated lipid peroxidation after torsion/detorsion in ipsilateral testis (p Erdosteine treatment caused increased glutathione peroxidase activity in comparison with torsion and torsion/detorsion groups and catalase activity in comparison with the other groups in ipsilateral testis (p erdosteine groups than control and torsion groups (p erdosteine groups showed ipsilateral testicular damage in the histological examination, but the specimens from torsion/detorsion had a significantly greater histological injury than those from the other groups (p erdosteine group, the testicular tissues were affected with slight-to-moderate degenerative changes of the seminiferous epithelium. Administration of erdosteine resulted in a significantly reduced histological damage associated with torsion of the spermatic cord compared with torsion

    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 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).

    Testicular torsion is predominantly a disease of adolescence, but age itself should not be an exclusion criterion for the diagnosis. A lack of suspicion for testicular torsion in older patients may result in a missed or delayed diagnosis which jeopardizes the chance of testicular salvage. In this article, we report a case of testicular torsion in a 55-year-old Chinese man.

    2004-01-01

    Spermatogenesis is a complex process regulated by endocrine and testicular paracrine/autocrine factors.Gonadotropins are involved in the regulation of several testicular paracrine factors, mainly of the IL-1 family and testicular hormones. Testicular cytokines and growth factors (such as IL-1, IL-6, TNF, IFN-T, LIF and SCF) were shown to affect both the germ cell proliferation and the Leydig and Sertoli cells functions and secretion. Cytokines and growth factors are produced by immune cells and in the interstitial and seminiferous tubular compartments by various testicular cells, including Sertoli, Leydig, peritubular cells, spermatogonia, differentiated spermatogonia and even spermatozoa. Corresponding cytokine and growth factor receptors were demonstrated on some of the testicular cells. These cytokines also control the secretion of the gonadotropins and testosterone in the testis. Under pathological conditions the levels of pro-inflammatory cytokines are increased and negatively affected spermatogenesis. Thus,the expression levels and the mechanisms involved in the regulation of testicular paracrine/autocrine factors should be considered in future therapeutic strategies for male infertility.

  3. Epigenetic: a molecular link between testicular cancer and environmental exposures?

    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.

    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.

    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.

    Full Text Available The two major functions of the testis, steroidogenesis and gametogenesis, take place during fetal life. These two functions have been extensively studied in rodents and adult humans. However, their onset during fetal life is poorly documented in humans. In the first part of this work we presented both our experimental data and some data of literature concerning the development of the human fetal testis. In the second part of this article, using the organ culture system we previously developed, we have investigated the regulations or perturbations of fetal testis development both in rodent and human models. Our findings provide important insight into the potential role of exposure to environmental pollutants (physical factors, in particular ionizing radiation, cadmium and endocrine disruptors such as phthalates during fetal testicular development and their potential deleterious effects on male fertility in adulthood. Our results highlight the specificity of the human model compared with rodent models.

    Effects on gonads in prenatal male fetuses, and on the postnatal testicular development and reproductivity of male offspring were studied following exposure of pregnant Wistar rats to either accelerated carbon-ion beans with a Let value of about 13 keV/L]m or neon-ion beams with a Let value of about 30 keV/I Im at a dose range from 0.1 Gy to 2.0 Gy on gestation day 15. Induction of apoptosis in fetal gonocytes was evaluated pathologically in male gonads. Mean number of pups, pre-weaning mortality, and the age for testis descent in offspring were examined. Testis weight and the ratio of it to body weight were measured on postnatal days 30, 60 and 90, respectively. Development of testicular tubules was analyzed histologically. In addition, in the male offspring, the successful mating rates with non-irradiated female rats, the mean number of pups descended, and, the weaning rates of the pups were investigated. The effects of X-rays at 200 kVp estimated for the same biological end points were studied for comparison. For heavy ions, a dose of 2.0 Gy caused 100% pre-weaning mortality. For some endpoints, such as pre-weaning mortality, testis weight, and ratio of testis weight to body weight, significant alteration was observed in offspring prenatally received only 0.1 Gy of accelerated neon ions; while for the most endpoints regarding the effects from carbon ions or X rays, a significant alteration could be observed only when a dose was at 0.5 Gy or more. In this dose range, apoptosis in gonocytes of fetal gonads was significantly induced in a dose-dependent manner with a peak at around 12 to 18 hr after irradiation; in the prenatally irradiated pups, statistical significances for increased prenatal death, delayed accomplishment in testis descent, low testis weight, changed ratios of testis weight to body weight, and increased malformed testicular tubules were recorded. When the dose was at 1.0 Gy or 1.5 Gy, marked decrease in successful mating rates was also observed

  19. Multiple vascular anomalies involving testicular, suprarenal arteries and lumbar veins

    Full Text Available Testicular arteries arise from the abdominal aorta and the inferior suprarenal artery from the renal artery. There are reports about variant origin and course of these arteries. Accessory testicular artery is also a common finding but its providing origin to inferior suprarenal artery is an important observation. During a routine dissection of abdomen of approximately 55-year-old male cadaver, unique vascular abnormality was observed. On the left side, a common arterial trunk originating from abdominal aorta immediately branched to give rise to superior testicular and inferior suprarenal arteries, the former after a short course hooked by the left suprarenal vein. In addition, the left suprarenal vein, second left lumbar vein, and left testicular vein joined to form a common trunk which drained into the left renal vein. A sound knowledge of vascular variations in relation to the kidney and suprarenal gland is important to surgeons dissecting the abdominal cavity.

    Segmental testicular infarction can mimic testicular carcinoma on sonography and can lead to unnecessary orchiectomy. This case series describes and correlates sonographic and histologic findings of 7 pathologically proven segmental testicular infarction cases. Segmental testicular infarction should be suspected on sonography when a geographic lesion with low or mixed echogenicity has absent or near-absent flow in a patient with scrotal pain. A hyperechoic rim and peripheral hyperemia correspond to interstitial hemorrhage and inflammatory changes. As an infarct evolves, it becomes more discrete and hypoechoic as ghost outlines replace seminiferous tubules. Follow-up or contrast-enhanced magnetic resonance imaging or sonography can increase diagnostic confidence in suspected cases and prevent unnecessary orchiectomy.

    Aim: To report two cases of the left testicular artery arching over the left renal vein (LRV) before running downward to the testis. Methods: The subjects were obtained from two Japanese cadavers. During the student course of gross-anatomical dissection, the anatomical relationship between the testicular vessels and the renal vein was specifically observed. Results: The arching left testicular artery arose from the aorta below the LRV and made a loop around the LRV, which appeared to be mildly compressed between the arching artery and the psoas major muscle.Conclusion: Clinically, compression of the LRV between the abdominal aorta and the superior mesenteric artery occasionally induces LRV hypertension, resulting in varicocele, orthostatic protenuria and hematuria. Considering that the incidence of a left arching testicular artery is higher than that of a right one, an arching left artery could be an additional cause of LRV hypertension.

    Full Text Available Metachronous bilateral testicular germ cell tumors is a rare known problem. However, no report of metachronus bilateralism was identified in the PubMed database published from India so far, where testicular cancer is relatively rare. We report the cases of two gentlemen. One had stage 1 nonseminomatous germ cell tumor (NSGCT at the age of 32 in 1990 and developed marker relapse on surveillance and had chemotherapy using cisplatin and etoposide for four cycles. He developed contralateral seminoma in the testis 13 years later. Another patient had left orchidectomy in 2003 for NSGCT, had adjuvant BEP for two cycles, and developed a contralateral testicular tumor 5 years later, which was also seminoma. As more patients with germ cell tumors are cured with chemotherapy, long-term problems become important. Contralateral testicular tumor is one of them. As it can be very late, many years of continued follow-up examination and patients′ awareness are necessary.

    Full Text Available Splenic cysts are rare entities and are classified as true cysts or pseudocysts based on the presence of an epithelial lining. Congenital nonparasitic true cysts can be epidermoid, dermoid, or endodermoid, present at a young age, and are commonly located in the upper pole of the spleen. Surgical treatment is recommended for symptomatic, large (more than 5 cm, or complicated cysts. Depending on cyst number, location, relation to hilus, and the major splenic vessels, the surgical options include aspiration, marsupialization, cystectomy, partial cystectomy (decapsulation, and partial or complete splenectomy. Laparoscopic techniques have now become the standard approach for many conditions, including the splenic cysts, with emphasis on the spleen-preserving minimally invasive operations. We present the successful extended partial laparoscopic decapsulation of a giant epidermoid splenic cyst in a young female patient that, although asymptomatic, was unfortunately followed by complete splenectomy five days later due to a misinterpreted abdominal CT suggesting splenic postoperative ischemia.

    Botox® injections are taking a consistently increasing place in urology. Intracremasteric injections, particularly, have been applied for cryptorchidism and painful testicular spasms. Studies outlining their safety for this use are, however, scanty. Thus, the present study aimed at evaluating possible testicular toxicity of Botox® injections and their effect on male fertility. Mature rats were given intracremasteric Botox® injections (10, 20 and 40 U/kg) three times in a two-week interval. Changes in body and testes weights were examined and gonadosomatic index compared to control group. Semen quality, sperm parameters, fructose, protein, cholesterol and triglycerides contents were assessed. Effects on normal testicular function were investigated by measuring testosterone levels and changes in enzyme activities (lactate dehydrogenase-X and acid phosphatase). To draw a complete picture, changes in oxidative and inflammatory states were examined, in addition to the extent of connective tissue deposition between seminiferous tubules. In an attempt to have more accurate information about possible spermatotoxic effects of Botox®, flowcytometric analysis and histopathological examination were carried out. Botox®-injected rats showed altered testicular physiology and function. Seminiferous tubules were separated by dense fibers, especially with the highest dose. Flowcytometric analysis showed a decrease in mature sperms and histopathology confirmed the findings. The oxidative state was, however, comparable to control group. This study is the first to show that intracremasteric injections of Botox® induce adverse testicular effects evidenced by inhibited spermatogenesis and initiation of histopathological changes. In conclusion, decreased fertility may be a serious problem Botox® injections could cause. - Highlights: • Botox® injections are the trend nowadays, for both medical and non-medical uses. • They were recently suggested for cryptorchidism and

    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.

    Full Text Available The incidence of secondary neoplasms of the testis during autopsies is approximately 2.5%. Although most secondary testicular metastases are due to prostate cancer, only a few patients with prostate cancer have clinically manifested testicular metastasis. We report the case of a prostate cancer patient with testicular metastasis who was diagnosed after the presence of a palpable mass in the right testis. A 56-year-old Japanese male presented to our hospital with an elevated serum prostate-specific antigen (PSA level of 137 ng/ml. He was diagnosed with stage IV (T3N1M1b prostate cancer and received androgen deprivation therapy, followed by various hormonal manipulations. His serum PSA level was undetectable for 1 year. No distant metastases were detected during imaging examinations. He received radiation therapy; however, his serum PSA level increased gradually. Four months later, he presented with right testicular swelling. Computed tomography revealed a heterogenous mass in the right testis and a right high inguinal orchiectomy was performed. Histopathological analysis showed that the right testis was infiltrated with metastatic adenocarcinoma with a Gleason score of 8. This is a rare case of right testicular metastasis in a patient with prostate cancer. Testicular metastasis of prostate cancer can be aggressive and metastasize.

A diagnosis of bile duct cysts is difficult to make in adults, since patients rarely present the classic picture of abdominal pain, palpable mass and jaundice; it is mainly presented as a biliary duct or pancreatic tissue complication. There are few publications on this topic in the west. A diagnosis can be made by ultrasound in many cases and is the image study of choice due to its low cost and accessibility. These are only few western publications concerning this subject. The importance of making an early diagnosis, classification and surgical treatment (total resection of the cyst lies in the high risk of malignancy developing.

    Testicular germ cell tumors are neoplasms carrying two unique features. First, testicular germ cell tumors have a pluripotential nature and show protean histology ranging from that of germ cells to embryonal and differentiated somatic cells. Therefore, testicular germ cell tumors are interesting resources positioned at a crossroad in developmental and neoplastic processes. The second unique feature of testicular germ cell tumors is their exquisite sensitivity to cisplatin-based chemotherapy. This review summarizes recent research progress in the epigenetics of testicular germ cell tumors in an attempt to explain the abovementioned biological and clinical characteristics of testicular germ cell tumors.

    Full Text Available Testicular atrophy is a rare but distressing complication of inguinal hernia repair. Apart from the postsurgical etiology, ischemic orchitis and subsequent testicular atrophy may occur secondary to compression of the testicular vessels by chronically incarcerated hernias. We present a rare case of testicular atrophy secondary to a large long standing incarcerated inguinal hernia of 2-decade duration in a 79-year-old man. Testicular atrophy should be always considered in long standing incarcerated inguinal hernias and patients should be adequately informed of this possibility during the preoperative work-up. Preoperative scrotal ultrasonography can be used to determine testicular status in this specific group of patients.

    2015-05-01

    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.

  1. Parents' choices in banking boys' testicular tissue.

    Murphy, Timothy F

    2010-12-01

    Researchers are working to derive sperm from banked testicular tissue taken from pre-pubertal boys who face therapies or injuries that destroy sperm production. Success in deriving sperm from this tissue will help to preserve the option for these boys to have genetically related children later in life. For the twin moral reasons of preserving access and equity in regard to having such children, clinicians and researchers are justified in offering the option to the parents of all affected boys. However, some parents may wish to decline the option to bank tissue from their boys because the technique may seem too unfamiliar or unusual, but over time people may become more comfortable with the technique as they have done with other novel assisted reproductive treatments (ARTs). Other parents may wish to decline the option because of moral or religious reasons. A prominent natural law theory holds, for example, that the ARTs that would be involved in using sperm derived from banked tissue to produce a child are morally objectionable. Some parents might not want to bank tissue in order to shield their son from using ARTs they see as objectionable. Clinicians and researchers should respect parents who wish to decline banking tissue, but parents should ordinarily embrace choices that protect the possible interests their sons may have as adult men, including the wish to have genetically related children.

Results: During the period, 285 testicular histologies were reported. Eighty-one (28.4% specimens were pathological specimens, while 204 (71.6% were nonpathological specimens. Thirty-seven (13.0% of the histology reports were for diagnostic purpose while 248 (87.0% were for therapeutic purpose. Based on the results, indications could also be categorized into three, benign testicular pathology, malignant testicular pathology, and testicular biopsy for male factor infertility. Thirty-seven cases (13.0% were due to male factor infertility with complete spermatogenic arrest as the most common histological finding in 21 (56.8% of the cases. Malignant testicular diseases accounted for 16 (5.6% of the indications for testicular biopsies. Benign testicular diseases accounted for 28 (9.8% of the indications for testicular biopsies. Hemorrhagic infarction from testicular torsion represented the commonest histology in 12 (42.9% cases, followed by inflammations of the testes. Conclusion: Indications for testicular biopsy can be diagnostic and therapeutic. They can also be categorized into benign testicular diseases, malignant testicular diseases, and male infertility. Investigation for male factor infertility was the only diagnostic indication for testicular biopsy. The high incidence of locally and metastatic prostate cancer in males explains why therapeutic removal of the testis is common.

    Aim: To find out the toxic effect of endosulfan on the tesficular function of pubertal rats, Methods: Male rats of pu-bertal age were orally administered endosulfan at a dose of 1.0 mg/kg body weight for 30 days. Twenty-four hours af-ter the last tmagnent, the rats were sacrificed and the testis, epididymis, seminal vesicles and ventral prostate were re-moved and weighed. A 10 % testicular homogenate was prepared for biochemical estimations. Results: In endosul-fan-treated rats, there were a reduction in the body weight and the weights of testis and accessory sex organs, a de-crease in the testicular lactate and pyruvate activities, and in the testicular DNA and RNA concentrations, whereas thetesticular protein concentration was slightly increased; the specific activity of testicular steroidogenic enzyme, 33OH-steroid dehydrogenase and the ascorbic acid level were decreased, which were correlated with a decrease in steroidoge-nesis. The lysosomal enzyme acid phosphatase and brush-border enzyme alkaline phosphatase activities were also de-creased in the testis of treated rats. Conclusion: In puhertal rats, endosulfan treaanent inhibits the testicular functions.(Asian J Androl 1999 Dec; 1 : 203 - 206)

    Nitrate is a common contaminant in groundwater aquifers. Current study aimed at evaluating the potential testicular toxicity of sodium nitrate in rats. Sodium nitrate was given orally to rats at doses of 50, 100 or 200 mg/kg/day for 60 consecutive days. Sperm count and motility, daily sperm production and testis weight were significantly decreased specially at high doses. Testicular activity of lactate dehydrogenase-X, glucose-6-phosphate dehydrogenase, and acid phosphatase were inhibited in a dose-related manner. Lipid peroxides and hydrogen peroxide production were significantly increased in all treated animals. This was accompanied by inhibition of testicular activities of superoxide dismutase and glutathione peroxidase. Fifty mg/kg of sodium nitrate did not significantly alter catalase or glutathione reductase activity. Glutathione was significantly decreased by sodium nitrate in a dose-related manner. The decrease in sperm count and motility and daily sperm production was confirmed by histopathological studies which indicated chromatolysis, pyknosis and necrosis in spermatocytes. In conclusion, subchronic exposure of rats to sodium nitrate results in testicular toxicity as evidenced by decreased sperm count and motility, daily sperm production and testis weight, inhibited activity of enzyme markers of spermatogenesis and induction of histopathological changes. These effects are attributed, at least partly, to testicular oxidative stress.

    Photodynamic therapy (PDT), a novel and promising cancer treatment that employs a combination of a photosensitizing chemical and visible light, induces apoptosis in human epidermoid carcinoma A431 cells. However, the precise mechanism of PDT-induced apoptosis is not well characterized. To dissect the pathways of PDT-induced apoptosis, we investigated the involvement of mitochondrial damage by examining a second generation photosensitizer, the silicon phthalocyanine 4 (Pc 4). By using laser-scanning confocal microscopy, we found that Pc 4 localized to cytosolic membranes primarily, but not exclusively, in mitochondria. Formation of mitochondrial reactive oxygen species (ROS) was detected within minutes when cells were exposed to Pc 4 and 670-675 nm light. This was followed by mitochondrial inner membrane permeabilization, depolarization and swelling, cytochrome c release, and apoptotic death. Desferrioxamine prevented mitochondrial ROS production and the events thereafter. Cyclosporin A plus trifluoperazine, blockers of the mitochondrial permeability transition, inhibited mitochondrial inner membrane permeabilization and depolarization without affecting mitochondrial ROS generation. These data indicate that the mitochondrial ROS are critical in initiating mitochondrial inner membrane permeabilization, which leads to mitochondrial swelling, cytochrome c release to the cytosol, and apoptotic death during PDT with Pc 4.

    In the case of cutaneous malignant or non-malignant diseases, topical photodynamic therapy (PDT) with a temoporfin (mTHPC)-containing formulation would be advantageous. Unfortunately, mTHPC is a highly hydrophobic drug with low percutaneous absorption and novel mTHPC-loaded invasomes for enhanced skin delivery were developed. The purpose of this study was to investigate photodynamic efficacy of mTHPC-loaded invasomes in vitro in two cell lines, i.e. the human colorectal tumour cell line HT29 and the epidermoid tumour cell line A431. Invasomes are vesicles containing besides phospholipids a mixture of terpenes or only one terpene and ethanol. Dark toxicity, phototoxicity and intracellular localization of mTHPC were studied. Laser scanning microscopy indicated perinuclear localization of mTHPC. Results revealed that mTHPC-invasomes and mTHPC-ethanolic solution used at a 2μM mTHPC-concentration and photoirradiation at 20J/cm(2) were able to reduce survival of HT29 cells and especially of A431 cells, being more sensitive to PDT. In contrast to HT29 cells, where there was not a significant difference between cytotoxicity of mTHPC-ethanolic solution and mTHPC-invasomes, in A431 cells mTHPC-invasomes were more cytotoxic. Survival of about 16% of A431 cells treated with mTHPC-invasomes is very promising, since it demonstrates invasomes' potential to be used in topical PDT of cutaneous malignant diseases.

    Honokiol is a plant lignan isolated from bark and seed cones of Magnolia officinalis. Recent studies from our laboratory indicated that honokiol pretreatment decreased ultraviolet B-induced skin cancer development in SKH-1 mice. The aim of the present investigation was to study the effects of honokiol on human epidermoid squamous carcinoma A431 cells and to elucidate possible mechanisms involved in preventing skin cancer. A431 cells were pretreated with different concentrations of honokiol for a specific time period and investigated for effects on apoptosis and cell cycle analysis. Treatment with honokiol significantly decreased cell viability and cell proliferation in a concentration- and time-dependent manner. Honokiol pretreatment at 50 μmol/L concentration induced G0/G1 cell cycle arrest significantly (P Cdk4 and Cdk6 proteins and up-regulated the expression of Cdk's inhibitor proteins p21 and p27. Pretreatment of A431 cells with honokiol leads to induction of apoptosis and DNA fragmentation. These findings indicate that honokiol provides its effects in squamous carcinoma cells by inducing cell cycle arrest at G0/G1 phase and apoptosis.

    Conclusion: Testicular volume on scrotal ultrasound correlates well with severity of oligospermia in men with sub-fertility. While the critical mean testicular volume necessary for adequate spermatogenesis has not been determined, it appears there is an optimal testicular volume of 18–20 ml at which spermatogenesis is at its peak in sub-fertile Nigerian men.

    Full Text Available OBJECTIVE: To study the incidence of testicular and epididymal appendages in patients with cryptorchidism. MATERIALS AND METHODS: We studied 65 patients with cryptorchidism, totalizing 83 testes and 40 patients who had prostate adenocarcinoma and hydrocele (control group, totalizing 55 testes. The following situations were analyzed: I absence of testicular and epididymal appendages, II presence of testicular appendage only, III presence of epididymal appendage, IV presence of testicular and epididymal appendage, V presence of 2 epididymal appendages and 1 testicular appendage and VI presence of paradidymis or vas aberrans of Haller. RESULTS: In patients with cryptorchidism we found testicular appendages in 23 cases (41.8%, epididymal appendages in 9 (16.3%, testicular and epididymal appendage in 8 (14.5%, 2 epididymal appendages and 1 testicular in 1 (1.8% and absence of appendages in 14 (25.4%. In the control group, we found testicular appendages in 29 (34.9%, epididymal appendages in 19 (22.8%, testicular and epididymal appendage in 7 (8.4%, and absence of appendages in 28 (33.7%, we did not find 2 epididymal appendages in this group, and none of the patients in the 2 groups presented paradidymis or vas aberrans of Haller. CONCLUSION: The occurrence of testicular and epididymal appendages is quite variable. There was no statistically significant difference in the incidence and distribution of the testicular and epididymal appendages between patients with cryptorchidism and those from the control group.

    The effect of testicular irradiation on Leydig cell function has been studied in a group of boys irradiated between 1 and 5 years earlier for a testicular relapse of acute lymphoblastic leukemia. Six of the seven boys irradiated during prepubertal life had an absent testosterone response to HCG stimulation. Two of the four boys irradiated during puberty had an appropriate basal testosterone level, but the testosterone response to HCG stimulation was subnormal in three of the four. Abnormalities in gonadotropin secretion consistent with testicular damage were noted in nine of the 11 boys. Evidence of severe Leydig cell damage was present irrespective of whether the boys were studied within 1 year or between 3 and 5 years after irradiation, suggesting that recovery is unlikely. Androgen replacement therapy has been started in four boys and will be required by the majority of the remainder to undergo normal pubertal development.

  16. Lunar synchronization of testicular development and steroidogenesis in rabbitfish.

    Lunar synchronization of testicular development in the golden rabbitfish, Siganus guttatus, was assessed by measuring changes in sperm motility and conditions in the seminal plasma, and by in vitro production of steroid hormones in testicular fragments and sperm preparations. The duration and percentage of sperm motility was low 1 week before spawning (the new moon), but increased significantly on the day of spawning (the first lunar quarter). During the first lunar quarter, the osmolality decreased, but Ca(2+) concentration increased in the seminal plasma. These results suggest that spermiation occurs rapidly towards the specific lunar phase. Testicular fragments and sperm preparations were incubated with human chorionic gonadotropin (hCG) and two precursor steroid hormones, 17alpha-hydroxyprogesterone (17alpha-OHP) and testosterone (T), during the two lunar phases. The production of 11-ketotestosterone (11-KT) increased significantly when the testicular fragments were incubated with hCG at the first lunar quarter, while incubation of sperm preparations with 17alpha-OHP during the same moon phase resulted in a significant increase in 17alpha,20beta-dihydroxy-4-pregnen-3-one (DHP) production in the medium. These results suggest that 11-KT is produced in the somatic cells of the testis under the influence of gonadotropin, and that sperm can convert 17alpha-OHP to DHP. Additionally, steroidogenic activity was considered to increase toward the specific lunar phase. The synchronous increase in testicular activity supports the hypothesis that lunar periodicity is a major factor for the testicular development of S. guttatus.

  17. Viral-type orchitis: a potential mimic of testicular neoplasia.

    2009-10-01

    Orchitis of viral or presumed viral etiology is an uncommon cause of testicular pain or enlargement. Rarely orchitis is clinically or radiographically suggestive of neoplasia, resulting in a testicular biopsy or orchiectomy being performed. Between 1978 and 2004, 10 cases submitted in consultation were diagnosed as orchitis at the Massachusetts General Hospital. The patients were from 18 to 37 years of age and presented with testicular enlargement or a mass, pain, or both. Radiographic studies were suspicious for a neoplasm in all 5 cases in which results were available. The patients underwent testicular biopsy (2 cases), orchiectomy (6 cases), biopsy immediately followed by orchiectomy (1 case), or biopsy followed by orchiectomy 3 weeks later (1 case). The cases were submitted with diagnoses that included intratubular seminoma, intratubular germ cell neoplasia, unspecified, Sertoli cell hyperplasia, myeloid sarcoma, and lymphoma. Microscopic examination revealed preservation of the architecture of the testicular parenchyma, typically with hemorrhage and edema, with patchy inflammation in the form of a lymphohistiocytic infiltrate within seminiferous tubules and also between tubules. The intratubular infiltrate usually predominated. Immunohistochemical studies, performed in 7 cases showed a mixture of CD68+ histiocytes and CD3+ T cells, with few B cells (CD20+) and few granulocytes. Follow-up was available in 5 cases; all 5 patients were alive and well 11 months to 10 years after diagnosis. In the rare instance in which a testicular specimen with orchitis is submitted for pathologic evaluation, diagnosis may be difficult. Familiarity with the pathologic changes characteristic of orchitis will help avoid misdiagnosis.

    2016-08-01

    We present a rare case of cystic dysplasia of the testes in an adolescent boy who presented with testicular pain and found to have a palpable intratesticular mass. Ultrasound revealed an avascular cystic dilation of the testicle. Usually, a palpable intratesticular mass is malignant unless proven otherwise. However, on computed tomography scan, he was found to have agenesis of the ipsilateral kidney and dilation of the ipsilateral seminal vesicle. These findings were consistent with a congenital abnormality, suggesting that the testicular finding was likely cystic dysplasia of the testes, with low malignant potential. Thus, the patient did not undergo radical orchiectomy.

    Full Text Available Gynecomastia is the development of abnormal breast tissue in men. Relatively increased estrogen action on tissue level is believed to play a main role in the pathogenesis of the entity. Here, we describe a patient with painless gynecomastia presenting after cytotoxic chemotherapy for testicular cancer. Further investigations showed no evidence of disease progression, recurrence, or metastasis. We suggest that the clinicians should be aware that gynecomastia may follow cytotoxic chemotherapy for testicular cancer and does not reflect the return of malignancy. Turk Jem 2008; 12: 86-7

    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.

    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.

    Testicular cancer survival rates improved dramatically after cisplatin-based therapy was introduced in the 1970s. However, chemotherapy and radiation therapy are potentially carcinogenic. The purpose of this study was to estimate the risk of developing second primary cancers including the risk associated with primary histologic type (seminoma and non-seminoma) among testicular cancer survivors in Germany. We identified 16 990 and 1401 cases of testicular cancer in population-based cancer registries of East Germany (1961-1989 and 1996-2008) and Saarland (a federal state in West Germany; 1970-2008), respectively. We estimated the risk of a second primary cancer using standardized incidence ratios (SIRs) with 95% confidence intervals (95% CIs). To determine trends, we plotted model-based estimated annual SIRs. In East Germany, a total of 301 second primary cancers of any location were observed between 1961 and 1989 (SIR: 1.9; 95% CI: 1.7-2.1), and 159 cancers (any location) were observed between 1996 and 2008 (SIR: 1.7; 95% CI: 1.4-2.0). The SIRs for contralateral testicular cancer were increased in the registries with a range from 6.0 in Saarland to 13.9 in East Germany. The SIR for seminoma, in particular, was higher in East Germany compared to the other registries. We observed constant trends in the model-based SIRs for contralateral testicular cancers. The majority of reported SIRs of other cancer sites including histology-specific risks showed low precisions of estimated effects, likely due to small sample sizes. Testicular cancer patients are at increased risk especially for cancers of the contralateral testis and should receive intensive follow-ups.

    2013-01-01

    Background The Wnt/β-catenin/T cell factor (TCF) signaling pathway is important in the development of nonmelanoma skin cancers (NMSCs). Nitric-oxide-releasing nonsteroidal anti-inflammatory drugs (NO-NSAIDs) are chemopreventive agents consisting of a traditional NSAID attached to an NO-releasing moiety through a chemical spacer. Previously we showed that an aromatic spacer enhanced the potency of a particular NO-NSAID compared to an aliphatic spacer. Methods We synthesized an NO-releasing NSAID with an aromatic spacer (flurbiprofen benzyl nitrate, NBS-242), and using the human skin cancer cell line A-431, we evaluated its effects on cell kinetics, Wnt/β-catenin, cyclin D1, and caspase-3. Results NBS-242 inhibited the growth of A-431 cancer cells, being ~15-fold more potent than flurbiprofen and up to 5-fold more potent than NO-flurbiprofen with an aliphatic spacer, the half maximal inhibitory concentrations (IC50) for growth inhibition being 60 ± 4 μM, 320 ± 20 μM, and 880 ± 65 μM for NBS-242, NO-flurbiprofen, and flurbiprofen, respectively. This effect was associated with inhibition of proliferation, accumulation of cells in the G0/G1 phase of the cell cycle, and an increase in apoptotic cell population. NBS-242 cleaved β-catenin both in the cytoplasm and the nucleus of A-431 cells. NBS-242 activated caspase-3 whose activation was reflected in the cleavage of procaspase-3. To test the functional consequence of β-catenin cleavage, we determined the expression of cyclin D1, a Wnt-response gene. NBS-242 reduced cyclin D1 levels in a concentration dependent manner. Conclusion These findings establish a strong inhibitory effect of NBS-242 in A-431 human epidermoid carcinoma cells. NBS-242 modulates parameters that are important in determining cellular mass.

    The exposure to agrochemicals during farming activities affects the function of the reproductive system, as revealed by the increasing worldwide evidence of male infertility amongst farmers. The main objective of this study was to untangle the link between agricultural practices and male reproductive impairment due to chronic exposure to xenobiotics (such as agrochemicals) in conventional and organic farming environments. For this purpose, male wild mice (Mus musculus) populations from sites representing two distinct farming practices (conventional and organic farming systems) were used as bioindicators for observable effects of testicular damage, namely on a set of histological and cellular parameters: (i) relative volumetric density of different spermatogenic cells and interstitial space; (ii) damage in the seminiferous tubules and (iii) apoptotic cells in the germinal epithelium. Results showed that mice from the conventional farming site bioaccumulated higher Pb hepatic loads, while mice from the organic farming site tend to bioaccumulate higher Cd hepatic loads. In general, for the analyzed testicular damage related parameters, mice from the organic farming site showed a similar performance than mice from the reference site. Mice from the conventional farming site stood out not only by underperforming in most studied parameters, while displaying an association between Pb hepatic loads and the observed testicular structural and functional disruption, but also by the increased stress index (Integrated Biomarker Response value). This study highlights the potential damaging effects of conventional farming practices on testicular structure and function, under natural conditions, raising concern about ensuing fertility risks for farmers.

    Background: Torsion of the testis compromises blood flow through the spermatic cord; testicular ischemia results which if not diagnosed promptly and corrected surgically irrevocably damages the testis. Current diagnostic modalities aimed at rationalizing surgical exploration by demonstrating interruption of spermatic cord blood flow or testicular ischemia have limited applicability. Near infrared spectroscopy (NIRS) offers a non-invasive optical method for detection of ischemia; continuous wave and frequency domain devices have been used experimentally; no device customized for clinical use has been designed. Methods: A miniature spatially resolved NIRS device with light emitting diode light source was applied over the right and left spermatic cord and the difference in oxygen saturation between the two sides measured. Results: In a 14-month old boy with a history of unilateral testicular pain color Doppler ultrasonography was equivocal but the NIRS-derived tissue oxygen saturation index (TSI) was significantly reduced on the left side. Confirmation of torsion of the left testicle was made surgically. Conclusions: Spatially resolved NIRS monitoring of spermatic cord oxygen saturation is feasible in children, adding to prior studies of testicular oxygen saturation in adults. Customized device design and further clinical trials would enhance the applicability of NIRS as a diagnostic entity for torsion.

    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.

    Full Text Available Background: After improvements in various cancer treatments, life expectancy has been raised, but success in treatment causes loss of fertility in many of the survived young men. Cryopreservation of immature testicular tissues or cells introduced as the only way to preserve fertility. However, freezing has some harmful effects. Melatonin, a pineal gland hormone, has receptors in reproductive systems of different species. It is assumed that melatonin has free radical scavenger properties. Objective: The aim of this study was to evaluate the effects of melatonin on the cryopreserved testicular cells in mouse. Materials and Methods: Cells from 7- 10 days old NMRI mice testes were isolated using two step enzymatic digestion. The testicular cells were divided into two groups randomly and cryopreserved in two different freezing media with and without the addition of 100 μm melatonin. Finally, apoptosis of the cells was assayed by flow cytometry. Also, lactate dehydrogenase activity test was performed to assess the cytotoxicity. Results: The results of lactate dehydrogenase showed the nearly cytotoxic effect of melatonin. The results of flow cytometry showed increase in apoptosis in the cryopreserved cells in the media containing melatonin compared to the control group. Conclusion: The present study shows that melatonin has an apoptotic effect on cryopreserved mouse testicular cells.

    Bernie, Aaron M; Ramasamy, Ranjith; Schlegel, Peter N

    2013-01-01

    Azoospermia in men requires microsurgical reconstruction or a procedure for sperm retrieval with assisted reproduction to allow fertility. While the chance of successful retrieval of sperm in men with obstructive azoospermia approaches >90%, the chances of sperm retrieval in men with non-obstructive azoospermia (NOA) are not as high. Conventional procedures such as fine needle aspiration of the testis, testicular biopsy and testicular sperm extraction are successful in 20-45% of men with NOA. With microdissection testicular sperm extraction (micro-TESE), the chance of successful retrieval can be up to 60%. Despite this increased success, the ability to counsel patients preoperatively on their probability of successful sperm retrieval has remained challenging. A combination of variables such as age, serum FSH and inhibin B levels, testicular size, genetic analysis, history of Klinefelter syndrome, history of cryptorchidism or varicocele and histopathology on diagnostic biopsy have provided some insight into the chance of successful sperm retrieval in men with NOA. The goal of this review was to evaluate the preoperative factors that are currently available to predict the outcome for success with micro-TESE.

    Acquired inguinal herniation is a very common condition in stallions, usually leading to unilateral or bilateral castration to prevent future recurrence. Recently, several surgical techniques such as the standing laparoscopic peritoneal flap hernioplasty (SLPFH) have been developed to avoid herniation recurrence and also preserve the breeding activity of high economic value stallions. However, studies on SLPFH lack more comprehensive and systematic data about reproductive-related adverse effects and outcomes. The aim of this study was to evaluate whether SLPFH of the internal inguinal rings produces changes in the testicular blood flow in a 1-year follow-up. For that purpose, six healthy stallions were used and testicular blood flow was assessed before, 3, 6, and 12 months (T0, T3, T6, and T12) after the procedure. Blood flow was evaluated ultrasonographically, using the pulsed-wave color Doppler mode. Peak systolic velocity, end-diastolic velocity, the time-averaged maximum velocity, and the derived indexes (resistive index) and pulsatility index) of the testicular artery were measured in two localizations: in the spermatic cord and on the caudal epididymal edge of the testicle. On the spermatic cord, the peak systolic velocity of the testicular artery increased significantly at T12. However, on the epididymal edge location of the artery, the pulsatility and resistive indexes were decreased at T12 (P perfusion in stallions in a 1 year follow-up, although there was no effect on sperm production during this time. The spectral Doppler ultrasound is a useful tool to asses the testicular perfusion after reproductive surgical procedure and provides information which anticipates vascular supply compromise of the stallion testicles.

  11. Lymphovascular invasion in testicular germ cell tumors: clinicopathological correlates

    2013-08-01

    Full Text Available Introduction. We assessed clinical–pathological correlates of lymphovascular invasion in testicular germ–cell tumors.Material and methods. Archived pathology specimens from 145 patients treated by radical orchiectomy for testicular germ cell tumors at our institution in 1995–2006 were reanalyzed by a dedicated urologic pathologist, and the corresponding medical records were reviewed. The association of lymphovascular invasion with clinical and pathological parameters was tested using stepwise logistic regression analysis.Results. Lymphovascular invasion was identified in 38 (26% patients and was associated with younger age, testicular pain at presentation, elevated serum tumor markers, nonseminoma histology, and advanced clinical stage. Orchalgia was indicated as the impetus for referral in 67 (46% patients and characterized as a dull aching sensation, persistent or intermittent in nature. Among the 98 men diagnosed with clinical stage I, those presenting with testicular pain had a 1.8X–higher likelihood of lymphovascular invasion than those without pain (95% CI 1.13–14.9, p = 0.02, and patients with elevated serum tumor markers had an 8.5–fold increased probability of lymphovascular invasion than those presenting with normal tumor markers (CI 1.1–54.2, p = 0.05. Among men with nonseminoma histology, elevated tumor markers was the strongest predictor of lymphovascular invasion in both univariate and multivariate analyses (OR 5.05, 95% CI 1.16–21.8, p = 0.03.Conclusion. Providing pathologists with information on pre–orchiectomy tumor marker levels and, possibly, testicular pain at presentation may increase their vigilance in searching for lymphovascular invasion, potentially improving their diagnostic accuracy. Whether it may also translate into improved oncological outcomes needs further evaluation.

  12. Androgen action via testicular arteriole smooth muscle cells is important for Leydig cell function, vasomotion and testicular fluid dynamics.

    Directory of Open Access Journals (Sweden)

    Michelle Welsh

    Full Text Available Regulation of blood flow through the testicular microvasculature by vasomotion is thought to be important for normal testis function as it regulates interstitial fluid (IF dynamics which is an important intra-testicular transport medium. Androgens control vasomotion, but how they exert these effects remains unclear. One possibility is by signalling via androgen receptors (AR expressed in testicular arteriole smooth muscle cells. To investigate this and determine the overall importance of this mechanism in testis function, we generated a blood vessel smooth muscle cell-specific AR knockout mouse (SMARKO. Gross reproductive development was normal in SMARKO mice but testis weight was reduced in adulthood compared to control littermates; this reduction was not due to any changes in germ cell volume or to deficits in testosterone, LH or FSH concentrations and did not cause infertility. However, seminiferous tubule lumen volume was reduced in adult SMARKO males while interstitial volume was increased, perhaps indicating altered fluid dynamics; this was associated with compensated Leydig cell failure. Vasomotion was impaired in adult SMARKO males, though overall testis blood flow was normal and there was an increase in the overall blood vessel volume per testis in adult SMARKOs. In conclusion, these results indicate that ablating arteriole smooth muscle AR does not grossly alter spermatogenesis or affect male fertility but does subtly impair Leydig cell function and testicular fluid exchange, possibly by locally regulating microvascular blood flow within the testis.

    Testicular spermatozoa are utilized to achieve pregnancy in couples with severe male factor infertility. Several studies suggest that aneuploidy rates in spermatozoa are elevated at the testicular level in infertile patients compared to ejaculates of normal controls. However, essential data regarding aneuploidy rates between ejaculated and testicular spermatozoa in the same individuals is lacking. The purpose of our study was to compare aneuploidy rates at the testicular and post-testicular level from the same patients with persistently high sperm DNA damage. Ejaculates and testicular biopsies were obtained from eight patients with persistently high DNA damage (>30%). Both ejaculated and testicular samples were analyzed for sperm DNA damage and sperm aneuploidy for chromosomes 13, 18, 21, X, and Y. In addition, semen samples from ten normozoospermic men presenting for fertility evaluation served as a control group. A strong correlation between the alteration of spermatogenesis and chromatin deterioration was observed in our study. In the same individuals, testicular samples showed a significantly lower DNA damage compared to ejaculated spermatozoa (14.9% ± 5.0 vs. 40.6% ± 14.8, P<0.05), but significantly higher aneuploidy rates for the five analyzed chromosomes (12.41% ± 3.7 vs. 5.77% ± 1.2, P<0.05). While testicular spermatozoa appear favourable for ICSI in terms of lower DNA damage, this potential advantage could be offset by the higher aneuploidy rates in testicular spermatozoa.

    Full Text Available PURPOSE: The hypothesis of association between testicular torsion and hyperactive cremasteric reflex, worsened by cold weather, has not been proved. Thirteen studies in the literature evaluated this issue, with inconclusive results. The aim of the present study was to evaluate the seasonality of testicular torsion in a large subset of patients surgically treated in Brazil, and additionally to estimate the incidence of testicular torsion. MATERIALS AND METHODS: Brazilian Public Health System Database was assessed from 1992-2010 to evaluate hospital admissions associated with treatment of testicular torsion. Average monthly temperature between 1992-2010 was calculated for each region. RESULTS: We identified 21,289 hospital admissions for treatment of testicular torsion. There was a higher number of testicular torsions during colder months (p = 0.002. To estimate the incidence of testicular torsion, we have related our findings to data from the last Brazilian census (2010. In 2010, testicular torsion occurred in 1.4:100,000 men in Brazil. CONCLUSIONS:Testicular torsion occurred at an annual incidence of approximately 1.4:100,000 men in Brazil in 2010. Seasonal variations do occur, with a significant increase of events during winter. Our findings support the theory of etiological role of cold weather to the occurrence of testicular torsion. Strategies to prevent these events can be based on these findings.

  18. Involvement of retinoblastoma (Rb) and E2F transcription factors during photodynamic therapy of human epidermoid carcinoma cells A431.

    1999-03-11

    Photodynamic therapy (PDT), a promising new therapeutic modality for the management of a variety of solid malignancies and many non-malignant diseases, is a bimodal therapy using a porphyrin based photosensitizing chemical and visible light. The proper understanding of the mechanism of PDT-mediated cancer cell-kill may result in improving the efficacy of this treatment modality. Earlier we have shown (Proc. Natl. Acad. Sci. USA; 95: 6977-6982, 1998) that silicon phthalocyanine (Pc4)-PDT results in an induction of the cyclin kinase inhibitor WAF1/CIP1/p21 which, by inhibiting cyclins (E and D1) and cyclin dependent kinases (cdk2 and cdk6), results in a G0/G1-phase arrest followed by apoptosis in human epidermoid carcinoma cells A431. We have also demonstrated the generation of nitric oxide during PDT-mediated apoptosis (Cancer Res.; 58: 1785-1788, 1998). Retinoblastoma (pRb) and E2F family transcription factors are important proteins, which regulate the G1-->S transition in the cell cycle. Here, we provide evidence for the involvement of pRb-E2F/DP machinery as an important contributor of PDT-mediated cell cycle arrest and apoptosis. Western blot analysis demonstrated a decrease in the hyper-phosphorylated form of pRb at 3, 6 and 12 h post-PDT with a relative increase in hypo-phosphorylated pRb. Western blot analysis also revealed that PDT-caused decrease in phosphorylation of pRb occurs at serine-780. The ELISA data demonstrated a time dependent accumulation of hypo-phosphorylated pRb by PDT. This response was accompanied with down-regulation in the protein expression of all five E2F (1-5) family transcription factors, and their heterodimeric partners DP1 and DP2. These results suggest that Pc4-PDT of A431 cells results in a down regulation of hyper-phosphorylated pRb protein with a relative increase in hypo-phosphorylated pRb that, in turn, compromises with the availability of free E2F. We suggest that these events result in a stoppage of the cell cycle

    2001-01-01

    To demonstrate the effect of capsulotomy on the fertility of male rats. Methods: Testicular capsulotomy was carried out in immature (21 days) and adult (60 days) male rats. The fertility of them was assessed by cohabitation with proestrus females overnight and 20 days later, the females were examined for impregnation. Morphological changes at the site of the capsulotomy were observed under light microscope. Results: In rats capsulotomized at Day 60, the fertility was gradually depressed and all the rats completely lost their fertility 2 months post - operation. At that time, a partial regeneration of the capsule at the site of capsulotomy was observed. Immature rats capsulotomized at Day 21 were found to possess normal fertility at maturity. The capsulotomy site was almost completely recovered 60days post-operation. Conclusion: In male rats, testicular capsulotomy at the age of Day 60 will damage fertility.However, when capsulotomy is performed at Day 21, fertility is preserve.

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.

    Basic research results can provide new ideas and hypotheses to be examined in epidemiological studies. We conducted a survey among testicular cancer researchers on hypotheses concerning the etiology of this malignancy. All researchers on the mailing list of Copenhagen Testis Cancer Workshops and corresponding authors of PubMed-indexed articles identified by the search term 'testicular cancer' and published within 10 years (in total 2750 recipients) were invited to respond to an e-mail-based survey. Participants of the 8th Copenhagen Testis Cancer Workshop in May 2014 were subsequently asked to rate the plausibility of the suggested etiologic hypotheses on a scale of 1 (very implausible) to 10 (very plausible). This report describes the methodology of the survey, the score distributions by individual hypotheses, hypothesis group, and the participants' major research fields, and discuss the hypotheses that scored as most plausible. We also present plans for improving the survey that may be repeated at a next international meeting of experts in testicular cancer. Overall 52 of 99 (53%) registered participants of the 8th Copenhagen Testis Cancer Workshop submitted the plausibility rating form. Fourteen of 27 hypotheses were related to exposures during pregnancy. Hypotheses with the highest mean plausibility ratings were either related to pre-natal exposures or exposures that might have an effect during pregnancy and in post-natal life. The results of the survey may be helpful for triggering more specific etiologic hypotheses that include factors related to endocrine disruption, DNA damage, inflammation, and nutrition during pregnancy. The survey results may stimulate a multidisciplinary discussion about new etiologic hypotheses of testicular cancer.

    It is extremely rare that a documented case of blunt trauma results in rupture of a testicular tumor. We present the case of a 24-year-old man who was crushed by a tree who developed spontaneous testicular rupture. At surgical exploration, he was found to ultimately have a mixed germ cell tumor of the testicle. This case illustrates the importance of physical examination, patient clinical history, and scrotal ultrasound in the management of scrotal trauma. In this instance, the testicular mass ruptured and lead to significant testicular hemorrhage.

    Full Text Available Isolated tubercular epididymo-orchitis usually presents with a clinical pictures and radiographic illustrations similar to those of a testicular neoplasm; therefore diagnosis may be challenging for clinicians. In our case, a 25years male presented with bilateral testicular swellings without any evidence of tuberculosis elsewhere in the body. We report this case firstly because isolated epididymo-orchitis is an unusual presentation of tuberculosis. Secondly this case may help clinicians in diagnostic approach when testicular tuberculosis masquerade testicular neoplasm, and thus avoids unnecessary orchiectomy and save the clinicians from the possible charges of medical negligence

  15. An unusual case of intra-abdominal testicular torsion: Role of laparoscopy

    2013-01-01

    Full Text Available The authors report a case of intra-abdominal testicular torsion, where laparoscopy has been useful for diagnosis and surgical management. A boy was presented with a left impalpable testis. Laparoscopy revealed a twisted spermatic cord at the inlet pelvis, which ended in a testicular remnant located in the sub-umbilical area. After orchiectomy, the pathologist confirmed testicular atrophy. Diagnosis of intra-abdominal testicular torsion should be considered in patients with impalpable testis and abdominal pain, but could not be excluded in those with no symptoms.

    Testicular torsion/detorsion induces oxidative/nitrosative stress, inflammation and apoptosis of testicular tissues. Baicalin exerts antioxidant and anti-inflammatory properties. This study investigated the possible protective effect of baicalin against testicular torsion-detorsion injury in rats. Surgical testicular torsion was induced for 2 h, followed by detorsion which was continued for 24 h. Baicalin was administered in three different doses (25, 50 and 100 mg kg(-1) , by intraperitoneal injection). Each dose was given twice, the first 30 min before and the second 12 h after testicular detorsion. Baicalin, in a dose-dependent manner, decreased the torsion/detorsion-induced elevations of testicular malondialdehyde, nitric oxide, tumour necrosis factor-α, BCL2-associated X protein (Bax), cytosolic cytochrome c and caspase-3 and caspase-9 activities. Baicalin, dose dependently, attenuated the reductions of B-cell leucemia/lymphoma 2 (Bcl-2), and glutathione peroxidase and superoxide dismutase activities in testicular tissues resulted from torsion/detorsion. In addition, baicalin ameliorated the histopathological testicular tissue damage and reduced the expression of Fas ligand in rat testes exposed to torsion/detorsion in a dose-dependent manner. It was concluded that baicalin, dose dependently, ameliorated testicular injury induced by torsion/detorsion via its antioxidant, antinitrosative, anti-inflammatory and anti-apoptotic effects.

    2012-01-01

    Full Text Available Altered thyroid function during early stages of development is known to affect adversely testicular growth, physiology, and antioxidant defence status at adulthood. The objective of the present study is to investigate the modulation of antioxidant defence status in neonatal persistent hypothyroid rats before their sexual maturation and also to identify the specific testicular cell populations vulnerable to degeneration during neonatal hypothyroidism in immature rats. Hypothyroidism was induced in neonates by feeding the lactating mother with 0.05% 6-n-propyl-2-thiouracil (PTU through the drinking water. From the day of parturition till weaning (25 day postpartum, the pups received PTU through mother's milk (or drinking water and then directly from drinking water containing PTU for the remaining period of experimentation. On the 31st day postpartum, the animals were sacrificed for the study. An altered antioxidant defence system marked by elevated SOD, CAT, and GR activities, with decreased GPx and GST activities were observed along with increased protein carbonylation, disturbed redox status in hypothyroid immature rat testis. This compromised testicular antioxidant status might have contributed to poor growth and development by affecting the spermatogenesis and steroidogenesis in rats before puberty as indicated by reduced germ cell number, complete absence of round spermatids, decreased seminiferous tubule diameter, and decreased testosterone level.

    2015-01-01

    We report a case of a 27-year-old man who presented with a slowly growing left testicular swelling associated with mild pain over a period of 3 months. He was evaluated by his family physician with scrotal ultrasound and testicular tumour markers. He was diagnosed and treated as epididymo-orchitis and managed with antibiotics. When he later presented to us, he had an enlarged left testis with normal spermatic cord. Scrotal Doppler evaluation showed a globally enlarged left testis and epididymis with increased vascularity in the left testis, with the right testis being normal. Testicular tumour markers were normal. Fine-needle aspiration cytology of the left testis was suggestive of lymphoma. Exploration through an inguinal approach was carried out and a Chevassu manoeuvre with frozen section study was performed, which was reported as non-Hodgkin's lymphoma. Left radical orchidectomy was performed. Histopathology reported diffuse large B-cell lymphoma, of a germinal centre type. Contrast CT of the abdomen, chest and brain were normal. Sperm cryopreservation was carried out. The patient was started on chemotherapy with cyclophosphamide, hydroxydaunorubicin, oncovin, prednisone (CHOP) regime. PMID:25795748

    2013-01-01

    Full Text Available The testicular plasmocytoma represents only 5% of the non-germinative cell testicular tumors, and accounts for only 2% of all plasma cell neoplasms. Approximately, 50 cases of testicular plasmocytoma have been reported in medical literature; however, only 9 of these are isolated tumors without previous history or progression to multiple myeloma. A 47-year-old patient, presenting progressive and painless growth of the right testicle in the last four years, underwent surgical treatment in another hospital two years ago, to correct a hydrocele in the same testicle with no improvement at all. Sonography showed a tumor with the following measurements for the right testicle: 84 × 59 × 80 mm. The tumor marker values were all normal. An abdominal computed tomography found no evidence of retroperitoneal lymph nodes invasion. The patient underwent a right radical orchiectomy. Pathologic analysis revealed a malignant neoplasia described as a plasmocytoma (solitary myeloma that produces immunoglobulin′s kappa light chain. After five years of follow-up, there were no signs of metastasis or local recurrence in the exams. Case report and review of literature have been presented here.

    Full Text Available Knowledge of variations of blood vessels of the abdomen is important during operative, diagnostic and endovascular pro- cedures. During routine dissection of the abdominal cavity, we came across multiple vascular anomalies involving renal, suprarenal and testicular arteries. The left kidney was supplied by two renal arteries originating together from the abdomi- nal aorta, and the right kidney was supplied by two accessory renal arteries, one of which was arising from the right renal artery and the other one from the aorta (about 2 inches below the origin of the renal artery. Accessory renal veins were present on both sides. The right testicular artery was arising from the lower accessory renal artery. The left testicular artery was looping around the inferior tributary of the left renal vein, whereby forming a sharp kink. The left middle suprarenal artery was diving into three small branches; the upper two branches were supplying the left suprarenal gland, whereas the lower branch was supplying the left kidney. Furthermore, detailed literature and the clinical and surgical importance of the case are discussed. [Arch Clin Exp Surg 2015; 4(3.000: 168-171

    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)

    This study investigated the protective effects of melatonin (MLT) against doxorubicin (DXR)-induced testicular toxicity and oxidative stress in rats. DXR was given as a single intraperitoneal dose of 10 mg kg(-1) body weight to male rats at 1 h after MLT treatment on day 6 of the study. MLT at 15 mg kg(-1) body weight was administered daily by gavage for 5 days before DXR treatment followed by an additional dose for 5 days. Sperm analysis, histopathological examination and biochemical methods were used for this investigation. DXR caused a decrease in the weight of seminal vesicles, epididymal sperm count and motility and an increase in the incidence of histopathological changes of the testis. In addition, an increased malondialdehyde (MDA) concentration and decreased glutathione content, glutathione reductase (GR), glutathione-S-transferase (GST), superoxide dismutase (SOD) and catalase activities were observed. On the contrary, MLT treatment significantly ameliorated DXR-induced testicular toxicity in rats. Moreover, MDA concentration and GR, GST and SOD activities were not affected when MLT was administered in conjunction with DXR. These results indicate that MLT had a protective effect against DXR-induced testicular toxicity and that the protective effects of MLT may be due to both the inhibition of lipid peroxidation and increased antioxidant activity.

    Stem Leydig cells (SLCs), located in the testicular interstitial compartment in the mammalian testes, are capable of differentiating to testosterone-synthesizing Leydig cells (LCs), thus providing a new strategy for treating testosterone deficiency. However, no previous reports have identified and cultured SLCs derived from the pig. The aim of the current study was to isolate, identify, and culture SLCs from pigs. Haematoxylin and eosin staining and immunochemical analysis showed that SLCs were present and that PDGFRα was mainly expressed in the pig testicular interstitium, indicating that PDGFRα was a marker for SLCs in the neonatal pig. In addition, reverse transcription-PCR results showed that SLC markers were expressed in primary isolated LCs, indicating that they were putative SLCs. The putative SLCs were subsequently cultured with a testicular fluid of piglets (pTF) medium. Clones formed after 7 days and the cells expressed PDGFRα. However, no clones grew in the absence of pTF, but the cells expressed CYP17A1, indicating that pTF could sustain the features of porcine SLCs. To summarize, we isolated porcine SLCs and identified their basic characteristics. Taken together, these results may help lay the foundation for research in the clinical application of porcine SLCs.

    Purpose. - To identify prognostic factors and treatment toxicity in a series of epidermoid cancers of the anal canal without evident metastasis. Patients and methods. - Between June 1972 and January 1997, 305 patients (pts) were treated with curative-intent radiation therapy (RT). The T-stages according to the 1987 UICC classification were: 26 T1, 141 T2, 104 T3, and 34 T4. There were 49 pts with nodal involvement at presentation. Pretreatment anal function scoring according to our in-house system was: 22 scored 0, 182 scored 1, 74 scored 2, 7 scored 3. 11 scored 4, and 9 not available pts. The treatment started with external beam RT (EBRT) in 303 pts (median dose: 45 Gy). After a rest period of 4 to 6 weeks, a boost of 20 Gy was delivered by EBRT in 279 pts and by interstitial {sup 192}Ir brachytherapy (Bcy) in 17 pts. Seven pts received only one course of EBRT (mean dose: 49.5 Gy) and 2 pts were treated with interstitial {sup 192}Ir Bcy alone (55 and 60 Gy, respectively). concomitant chemotherapy (5-fluoro-uracil and either mitomycin C or cisplatin) was delivered to 19 pts. Mean follow-up was 103 months. Results. - At the end of RT local tumor clinical complete response (cCR) rate was 80%. Out of 61 non responders or local progressive tumors 27 (44%) were salvaged with abdomino-perineal resection (APR). The rate of local tumor relapse (LR) was 12%. Out of 37 LTR, 20 (54%) were salvaged with APR and one with interstitial {sup 192}Ir Bcy. The overall local tumor control (LC) rate with or without salvage local treatment was 84%. LC rate with a good anal function scoring (score 0 and 1) was 56.5%0. Among 181/186 available pts who preserved their anus, 94% had a good anal function scoring. For a subgroup of 15 pts with length tumor <2 cm-N0, the LC rate after the end of RT was 100% the LC rate with or without local salvage treatment was 100%, and among 13 available pts who preserved their anus, the anal function scoring was good in 12 pts (92%).

    Full Text Available Most testicular neoplasms originate from fetal germ cells (germ cell tumors [GCT]. Intratubular germ cell neoplasia (ITGCN or testicular carcinoma in situ (CIS are terms used for the state when these cells are present in the seminiferous epithelium. The highest risk of neoplastic lesions occurs in testes with disturbed organogenesis (in our study, 65 %. Genetic, hormonal, and environmental factors are suspected to lead to disturbed testicular organogenesis (dysgenesis, which creates the milieu favorable for GCT development. An external environment can cause a block or delay in fetal germ and somatic cell differentiation. CIS cells in dysgenetic testes of children reveal a predominantly aneuploid DNA pattern (62.2–97.6 % of germ cells and they do not express an RBM protein (present in normal germ cells, this indicates that CIS cells are neoplastic from fetal life on. Most of the neoplastic germ cells die, however, some survive and proliferate, leading to a clonal expansion and giving rise to gonadoblastoma, CIS, and GCT. Neoplastic germ cells located inside underdeveloped testicular tubules have an intratesticular environment favorable for their survival – this was confirmed by the finding that the highest incidence of neoplastic lesions occurred in patients with partial (90.9 % and mixed gonadal dysgenesis (76.9 %. It was hypothesized that the transformation of CIS into overt GCT may be promoted by gonadotropin action. We found that in gonadal dysgenesis, serum concentrations of FSH and LH reveal highly significant, positive correlations with the number of CIS cells, even in childhood. At present, surgical biopsy of the testis is the only reliable method to detect CIS and hence to actively prevent the development of overt GCT. Accordingly, early bilateral gonadectomy is recommended in all types of disturbance of testicular organogenesis because of the high risk of various neoplastic lesions in dysgenetic testes (86 % of adult patients with

    The combination of hydroxocobalamin (vitamin B12b) and ascorbic acid (vitamin C) can cause the death of tumor cells at the concentrations of the components at which they are nontoxic when administered separately. This cytotoxic action on epidermoid human larynx carcinoma cells HEp-2 in vitro is shown to be due to the hydrogen peroxide generated by the combination of vitamins B12b and C. The drop in the glutathione level preceding cell death was found to be the result of combined action of the vitamins. It is supposed that the induction of cell death by combined action of vitamins B12b and C is connected to the damage of the cell redox system.

    Familial aggregation of testicular cancer has been reported consistently, but it is less clear if there is any association between risk of testicular cancer and other cancers in the family. We conducted a population-based case-control study to examine the relationship between risk of testicular cancer and 22 different cancers in first-degree relatives. We included 3,297 cases of testicular cancer notified to the Danish Cancer Registry between 1991 and 2003. A total of 6,594 matched controls were selected from the Danish Civil Registration System, which also provided the identity of 40,104 first-degree relatives of case and controls. Familial cancer was identified by linkage to the Danish Cancer Registry, and we used conditional logistic regression to analyze whether cancer among first-degree relatives was associated with higher risk of testicular cancer. Rate ratio for testicular cancer was 4.63 (95% CI: 2.41-8.87) when a father, 8.30 (95% CI: 3.81-18.10) when a brother and 5.23 (95% CI: 1.35-20.26) when a son had testicular cancer compared to no familial testicular cancer. Results were similar when analyses were stratified by histologic subtypes of testicular cancer. Familial non-Hodgkin lymphoma and esophageal cancer were associated with testicular cancer; however, these may be chance findings. The familial aggregation of testicular and possibly other cancers may be explained by shared genes and/or shared environmental factors, but the mutual importance of each of these is difficult to determine.

    Non-melanoma skin cancers (NMSCs), one of the most common neoplasms, cause serious morbidity and mortality. Therefore, identification of non-toxic phytochemicals for prevention/treatment of NMSCs is highly desirable. Fisetin (3,3',4',7-tetrahydroxyflavone), a dietary flavonoid, present in fruits and vegetables possesses anti-oxidant and antiproliferative properties. The aim of this study was to investigate the chemotherapeutic potential of fisetin in cultured human epidermoid carcinoma A431 cells. Treatment of A431 cells with fisetin (5-80 μm) resulted in a significant decrease in cell viability in a dose- and time-dependent manner. Employing clonogenic assay, we found that fisetin treatment significantly reduced colony formation in A431 cells. Fisetin treatment of A431 cells resulted in G₂ /M arrest and induction of apoptosis. Furthermore, treatment of A431 cells with fisetin resulted in (i) decreased expression of anti-apoptotic proteins (Bcl2; Bcl-xL and Mcl-1); (ii) increased expression of pro-apoptotic proteins (Bax, Bak and Bad); (iii) disruption of mitochondrial potential; (iv) release of cytochrome c and Smac/DIABLO from mitochondria; (v) activation of caspases; and (vi) cleavage of Poly(ADP-ribose) polymerase (PARP) protein. Pretreatment of A431 cells with the pan-caspase inhibitor (Z-VAD-FMK) blocked fisetin-induced cleavage of caspases and PARP. Taken together, these data provide evidence that fisetin possesses chemotherapeutic potential against human epidermoid carcinoma A431 cells. Overall, these results suggest that fisetin could be developed as a novel therapeutic agent for the management of NMSCs.

    A self-induced, non-traumatic testicular torsion is a rare entity that to our knowledge has not been reported in the literature. We report the case of a 28-year-old male who caused a self-induced testicular torsion during acts associated with cross dressing. Differential diagnosis of the acute scrotum in an adult should always include testicular torsion, as outcomes in this population are worse than in younger populations. Additional unusual causes of testicular torsion are reviewed.

    Testicular dislocation after blunt perineal trauma is a rare event and a diagnosis that can be easily overlooked. Careful examination can help facilitate early and appropriate treatment. Timely diagnosis and surgical management are of paramount importance to preserve normal spermatogenic function in the dislocated testicle. We describe a case of testicular dislocation and discuss some of the issues surrounding diagnosis and treatment.

    Despite the genitourinary tract being the most common site affected by extrapulmonary TB, isolated testicular TB remains a rare clinical entity. In patients with co-morbidities such as hepatic impairment, treatment proves a challenge, as first-line hepatotoxic pharmaceuticals are contraindicated. Here, we report a case of isolated testicular TB with scrotal involvement, on a background of hepatic dysfunction.

    Full Text Available Objetivou-se com este trabalho observar as mudanças do parênquima testicular de acordo com o fotoperíodo e com a faixa etária dos animais por meio da ecotextura testicular e a viabilidade do uso do ultrassom na avaliação testicular. Foram utilizados 4 animais desde o 6° até o 13° mês de idade. Os exames ecográficos foram realizados a cada 15 dias para avaliar a ecotextura testicular. O parênquima testicular mostrou-se moderadamente ecogênico e homogêneo. Foi observado comportamento semelhante na ecotextura testicular durante o período de avaliação, sendo maior no 8º mês de idade, quando o volume testicular também foi maior; tais mudanças foram relacionadas com o fotoperíodo da região. A avaliação ultrassonográfica dos testículos mostrou-se um método eficiente, capaz de detectar as mudanças no parênquima testicular ao longo do tempo, e como ferramenta alternativa para diferenciação de condições normais e patológicas em caprinos.

    Pseudoxantoma elasticum (PXE) is a rare chromosomal disorder that results in mineralization of elastic fibers, especially in the skin, eye, and cardiovascular system. Recently, PXE has been associated with testicular microlithiasis (TM),1 which itself might be associated with testicular malignancy.2
