    Full Text Available Introducción: La gran mayoría de las tumoraciones testiculares son de origen neoplásico, lo que determina habitualmente una cirugía radical. Los quistes epidermoides testiculares son una entidad benigna rara, que plantea dificultades en su diagnóstico clínico. Material y métodos: Se realizó una revi [...] sión de los tumores testiculares, encontrando 7 casos de quistes epidermoides. Dentro de la valoración preoperatoria se realizó ecografía escrotal y resonancia magnética en 6 y en 4 pacientes, respectivamente. En 4 casos se realizó también biopsia intraoperatoria. Resultados: Se encontró una imagen típica ecográfica en más del 80 y en el 50% de las resonancias. En las biopsias intraoperatorias realizadas se encontró un 100% de coincidencia con el diagnóstico definitivo de la pieza. Se tomó una conducta conservadora (orquiectomía parcial o tumorectomía) en 6 de los 7 casos (85%), con buena evolución. Conclusión: En los pacientes en que se tiene alta sospecha ecográfica de quiste epidermoide, las características macroscópicas típicas (tumor encapsulado, pequeño tamaño, amarillo nacarado y de fácil enucleación) y un examen con cortes por congelación en el intraoperatorio que confirme el diagnóstico permiten realizar una cirugía conservadora. Abstract in english Introduction: Testicular tumors are usually managed by radical orchiectomy because of the high incidence of malignant lesions. Epidermoid cyst of the testis is a rare benign tumor, and its differential diagnosis from malignant testicular tumors is difficult. Materials and methods: The clinical recor [...] ds of seven patients who attended our hospital with testicular epidermoid cysts were reviewed. Preoperative evaluation consisted of testicular ultrasonography in 6 patients, and magnetic resonance imaging in 4 patients. A peroperative biopsy was performed in four patients. Results: Ultrasonographic appearance was specific for diagnosis of epidermoid cyst in 80% of patients. Pathological diagnosis was made in all biopsies taken during surgery. Conservative management was (tumorectomy or partial orquidectomy) performed in 6 patients (85%). Conclusions: Preoperative imaging findings, gross characteristics of the lesion, and peroperative biopsy results provide adequate information to attempt testis-sparing surgery instead of radical orchiectomy.

    Full Text Available Objetivos: Los quistes epidermoides testiculares son muy infrecuentes y su diagnóstico preoperatorio suele plantear dificultades. Describimos un caso de quiste epidérmico testicular con el ánimo de contribuir al conocimiento clinicopatológico de esta entidad. Métodos: El caso clínico corresponde a u [...] n hombre de 24 años que consultó por una masa en testículo derecho, detectada por autopalpación, que por ecografía se etiquetó de tumor sólido. El paciente fue sometido a una orquiectomía radical. Resultados: Macroscopicamente se identificó una lesión quística intratesticular de 1,4 cm, que histológicamente estaba tapizada por una epidermis sin anejos, con abundantes láminas de queratina intraluminales; la pulpa testicular adyacente carecía de alteraciones. Conclusiones: Si los datos preoperatorios apoyan el diagnóstico de quiste epidérmico es razonable realizar un tratamiento conservador, que debe comprender estudio anatomopatológico intraoperatorio, incluyendo examen microscópico del quiste y del parénquima anexo para descartar la coexistencia de una neoplasia germinal intratubular. Abstract in english Objective: Testicular epidermoid cysts are rare and can be clinically misleading with other testicular neoplasms. We describe a case of epidermal cyst of the testis, with the aim to contribute to the clinicopathological knowledge of this entity. Methods: A 24-year-old caucasian man presented with a [...] self-detected right testicular mass. Ultrasound features were consistent with solid tumor. He underwent an inguinal radical orchyectomy. Results: An intraparenchymal cyst measuring 1,4 cm was observed, covered by epidermal epithelium with no other skin components. Adnexal testicular pulp was normal. Conclusions: When a preoperative diagnosis is made, a conservative treatment is recommendable, including frozen sections analysis of the cyst and adjacent testicular parenchyma to rule out a coexistent intratubular germ cell neoplasia.

  7. Concomitant bilateral testicular epidermoid cysts

    International Nuclear Information System (INIS)

    Epidermoid cyst of the testis is a rare benign germ tumor, comprising 1-2% of all resected benign testicular masses. Approximately 300 cases have been reported to date. Unilateral involvement has often been reported in the English literature. However, bilateral occurrence is very rare and to the best of our knowledge, there only 3 previous reports of bilateral testicular epidermoid cysts. The fact that they are completely benign makes them amenable to treatment by local excision, thereby saving patient from orchidectomy. Recognition of their characteristic ulatrsonographic features is very important to avoid unnecessary intervention. We present here, a case of bilateral epidermoid cyst in which characteristic ultrasound (US) findings allowed testis-sparing enucleation instead of radical orchiectomy. (author)

    Full Text Available Los quistes epidermoides son lesiones benignas en su mayoría, representando un 0,3 al 1,5% de los tumores intracraneanos y se originan por la inclusión de elementos epiteliales en el momento del cierre del tubo neural. Su presentación clínica está dada por compresión de estructuras adyacentes y con [...] menor frecuencia secundaria a la rotura espontánea causando meningitis química. Se presenta el caso clínico de un paciente de 34 años de sexo masculino que debuta con un cuadro de cefalea ictal y signos de irritación meníngea. La Tomografía computada de cerebro muestra una lesión hipodensa supraselar con signos de rotura hacia el sistema ventricular. La Resonancia Nuclear Magnética muestra una lesión predominantemente hipointensa en T1 e hiperintensa en T2 planteándose entre los diagnósticos posibles un quiste epidermoide. El paciente es operado y la biopsia informa un quiste epidermoide. La rotura de los quistes epidermoide hacia el espacio subaracnoideo o al ventrículo ocurre de forma espontánea, presentándose clínicamente con un síndrome meníngeo y puede ser causa de gran morbilidad. La rotura hacia el ventrículo es una presentación clínica descrita con poca frecuencia en la literatura. Abstract in english Epidermoid cyst are benign lesions representing 0,3-1,5% of intracranial tumors. They originate from inclusions of epithelials cells during closure of neural tube. Symptoms result from compression of adjacent structures or rarely due to rupture causing Chemical meningitis. In this report, we present [...] the case of a 34 years old male with history of ictal headache and meningeal signs. Brain CT showed hypodense suprasellar lesion with signs of rupture into the ventricular system. MRI showed a hypointense lesion on T1 and hyperintense on T2, suspecting epidermoid tumor. The Patient was operated and the sample demonstrated an epidermoid cyst. Spontaneous cyst rupture and spillage of the content into subarachnoid space or ventricles manifest as meningeal syndrome and cause high morbidity. Cyst rupture into de ventricle is infrequently described in literature.

Estudio de extensión y marcadores tumorales negativos. El paciente se encuentra libre de enfermedad tras 6 meses de seguimiento. Resultados: El teratoma testicular es un tumor compuesto por células derivadas de las tres hojas embrionarias (ectodermo, endodermo y mesodermo). Aparecen a cualquier edad, siendo mucho más incidentes en la infancia, donde llegan a representar hasta un 30% de todos los tumores. En la edad adulta es mucho menos prevalente, llegando sólo a representar un 7% de todos los tumores germinales del testículo. Conclusiones: Los casos prepuberales son casi invariablemente de carácter benigno, independientemente de su histología. Sin embargo, los casos que aparecen tras la pubertad presentan potencial maligno, incluso si es histológicamente puro. El teratoma quístico maduro (quiste dermoide) representa la única excepción a esta regla, ya que no se ha publicado ninguna degeneración maligna de este tipo de tumores. Abstract in english Objectives: Case report of a mature cystic teratoma (dermoid cyst), pseudopilomatrixoma like variant. Method: 53-year old patient with a left testicular mass, diagnosed as mature cystic teratoma of the testis (dermoid cyst), the pilomatrixoma-like variant, after radical orchiectomy. Tumoral markers [...] were negative and no extension was observed. The patient is disease-free after 6 months follow-up. Results: Testicular teratoma is a tumour composed of cells derived from the three embryonic layers (ectoderm, endoderm and mesoderm). They can appear at any age, but they are much more prevalent in childhood. They appear at any age, but are much more common in childhood, where they comprise up to 30% of all tumours. They are much less prevalent in adults, representing only 7% of all testicular germ cell tumours Conclusions: Prepubertal cases are invariably benign in nature, regardless of their histology. However, cases which appear after puberty are potentially malignant, even if histologically pure. Mature cystic teratoma (dermoid cyst) is the only exception to this rule, as no malignant degeneration of these types of tumours has been published.

Age, sex, way of presentation, location, radiologic features, surgical technique and complications of [...] 15 epidermal and 1 dermal tumors diagnosed between may 1997 and october 2006, were retrospectively assessed. Results. Mean age: 43 yrs. Most frequent clinical manifestation: headache. Most tumors were at CPA. All resections were done with microsurgical technique. There were 3 cases of chemical meningitis that resolve without sequel. Discussion. Dermal and epidermal cysts are originated by inclusion of ectodermic material at the moment of occlussion of the neural tube. They represent the 0,3 - 1,5% of intracranial tumors beeng dermal 5-9 times less frequent. The most frequent location of epidermal cysts is at the CPA while dermal are more frequent in the midline. Clinical fatures depend on location. MRI is the gold standard for diagnosis, specially the DWI sequence. CT is important for the detection of bone invasion. Treatement is so extensive as possible surgical resection, difficult, sometimes because of strong adhesions to eloquent structures. Conclusion. Dermal and epidermal cysts are high fat content lesions, that produce edherence to neural structures. Surgical excision is the election tratement.

  18. Epidermoid Cyst of the Testicle: Unusual Magnetic Resonance Imaging Findings

    International Nuclear Information System (INIS)

    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

  19. Epidermoid cyst of the testis: a case report

    International Nuclear Information System (INIS)

    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.)

    Full Text Available Intramedullary epidermoid cysts of the spinal cord are rare tumours, especially those not associated with spinal dysraphism. Around 50 cases have been reported in the literature. Of these, only seven cases have had magnetic resonance imaging studies. We report two cases of spinal intramedullary epidermoid cysts with MR imaging. Both were not associated with spina bifida. In one patient the tumour was located at D4 vertebral level, while in other within the conus medullaris. The clinical features, MR imaging characteristics and surgical treatment of such rare intramedullary benign tumours are discussed, and the relevant literature reviewed.

    Full Text Available Objetivo: La microlitiasis testicular (MT), que se caracteriza por la existencia de microcalcificaciones dentro de los túbulos seminíferos, es poco frecuente y generalmente constituye un hallazgo incidental durante la realización de la ecografía escrotal. Método: Presentamos un caso de un varón de 4 [...] 5 años de edad, sin factores de riesgo para el desarrollo de un tumor testicular de células germinales, diagnosticado de una microlitiasis testicular bilateral. Resultados: El paciente ha sido sometido a control evolutivo anual con ecografía testicular, sin desarrollar un tumor germinal durante un seguimiento de 4 años. Conclusiones: Aunque el significado clínico de la MT está en debate debido a las diferentes controversias halladas en la literatura sobre su asociación o no con el tumor testicular, así como los diferentes protocolos de manejo inicial y de los intervalos adecuados para su vigilancia y seguimiento, parece razonable realizar un control ecográfico anual, independientemente de la existencia o no de factores de riesgo asociados.

Results: The patient was followed yearly with testicular ultrasound, without evidence of germ cell tumor over a four-year follow-up period. Conclusions: Although the clinical significance oftesticular microlithiasis is under debate due to the various controversies found in the literature about its association or not with testicular tumors, as well as the various protocols for initial management and adequate intervals for follow-up, it seems reasonable to perform an ultrasound yearly independently of the existence or not of associated risk factors.

    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.

    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.

  13. Orbital dermoid and epidermoid cysts: Case study

    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.

    More than 90 percent of testicular cancer start in the germ cells, which are cells in the testicles and develop into sperm. This type of cancer is known as testicular germ cell cancer. Testicular germ cell cancer can be classified as either seminomas or nonseminomas, whose cells have different appearances under a microscope.1 Another difference is that nonseminomas typically grow and spread more quickly than seminomas.

    The ultrasound scan plays an essential role in the urological-andrological diagnosis. High-resolution transducers (8-15 MHz) make it possible to prove increasingly small changes. The assessment of cystic masses in the testis can also be difficult for experienced doctors. However, a precise diagnosis is crucial for the patient to avoid further invasive diagnostics and therapy. The differential diagnosis of benign intra-testicular cystic lesions include the tubular ectasia of the rete testis (TERT), the cystic dysplasia, epidermoid cysts, dermoid cysts, simple testicular cysts and cysts of the tunica albuginea. Malign testicular tumours with cystic changes are particularly the mature teratoma, carcinomas of the epididymis and metastasis. The following overview shows different sonographic images and interpretations with a particular focus on TERT. PMID:25847888

  1. High-density intracranial epidermoid tumors

    International Nuclear Information System (INIS)

    An intracranial epidermoid tumor appears as a low-density lesion on CT. This is a report on 3 cases of high-density intracranial epidermoids, which had been regarded as rare. In Case 1, one continuous tumor was noted in the bilateral cerebellopontine regions. A CT scan showed homogeneous high-density zones in the bilateral cerebellopontine-angle regions, with high-density spots indicating calcifications in the prepontine region. In Case 2, the tumor existed around the medulla and in the upper cervical spinal canal; it also seemed embedded in the pons. This tumor appeared on CT as a homogeneous high-density mass. In Case 3, the tumor was thought to have originated from Meckel's cave and to extend mainly into the extradural space in the middle fossa and in the subdural space in the posterior fossa on the right. On CT, this tumor seemed to be a dumbbell-shaped, inhomogeneous high-density mass which contained some low-density areas and peripheral high-density spots indicating calcifications. An obvious contrast enhancement was noted along the margin of the tumor. In each case, dark brown contents, indicating the existence of blood components, were obtained by surgery. These blood components are assumed to be the cause of the high density on CT. Moreover, in Case 3, the microscopic findings of operated-on specimens showed intramural hemorrhage. There were neovascularities in the cyst wall due to the organization of the blood components. It was considered that the blood coments. It was considered that the blood components in the cystic cavity were the result of a dissection of the intramural hemorrhage. The extravasation of the contrast material from the neovascularities into the extracellular space of the cyst wall was considered to be a main cause of the contrast enhancement in Case 3. Also shown was a characteristic pattern of the extension of epidermoids, a pattern which was revealed by reviewing the reported cases of epidermoids and our own cases. (author)

    OBJECT Epidermoid tumors arise from misplaced squamous epithelium and enlarge through the accumulation of desquamated cell debris. Optimal treatment consists of total removal of the capsule; therefore, giant and multicompartmental tumors are particularly challenging. A conservative attitude in handling the tumor capsule is common given concerns about capsule adherence to neurovascular structures, and thus the possibility of recurrence is accepted with the intent of minimizing complications. This study focuses on the outcome of surgery in patients with giant epidermoid tumors for which total capsule removal was the aim. METHODS The authors conducted a retrospective analysis of all patients with giant epidermoid tumors treated by the senior author (O.A.), who pursued total removal of the capsule through skull base approaches. Patients were divided into 2 groups: one including patients with de novo tumors and the other consisting of patients who presented with recurrent tumors. RESULTS Thirty-four patients had undergone 46 operations, and the senior author performed 38 of these operations in the study period. The average tumor dimensions were 55 × 36 mm, and 25 tumors had multicompartmental extensions. Total removal of the tumor and capsule was achieved with the aid of the microscope in 73% of the 26 de novo cases but in only 17% of the 12 recurrent tumor cases. The average follow-up among all patients was 111 months (range 10-480 months), and the average postsurgical follow-up was 56.8 months (range 6-137 months). There were 4 recurrences in the de novo group, and every case had had a small piece of tumor capsule left behind. One patient died after delayed rupture of a pseudoaneurysm. In the de novo group, the average preoperative Karnofsky Performance Scale (KPS) score was 71.42%, which improved to 87.14% on long-term follow-up. In the group with recurrences, the KPS score also improved on long-term follow-up, from 64.54% to 84.54%. In the de novo group, 3 cases (11.5%) had permanent cranial nerve deficits, and 4 cases (15.4%) had a CSF leak. In the recurrence group, 3 cases (25%) had new, permanent cranial nerve deficits, and 1 (8.3%) had a CSF leak. Two patients in this group developed hydrocephalus and required a shunt. CONCLUSIONS Total removal of the capsule of giant epidermoid tumors was achieved in 73% of patients with de novo tumors and was associated with improved function, low morbidity and mortality, and a lower risk of recurrence. Surgery in patients with recurrent tumors was associated with higher morbidity and persistence of the disease. PMID:25594324

    Full Text Available En el tratamiento de los quistes hidatídicos hepáticos se han experimentado diversas técnicas quirúrgicas que van desde la aspiración, drenaje, capitonaje o marsupialización, hasta la escisión completa del mismo acompañada de resección segmentaria hepática. Con el advenimiento de la cirugía laparosc [...] ópica se inician nuevas opciones de abordaje para esta patología relativamente frecuente en nuestro país. En el presente trabajo mostramos la técnica laparoscópica que usamos para el tratamiento de los quistes hidatídicos hepáticos. Se realiza el diagnóstico por criterios de imágenes, epidemiológico y de laboratorio. Se inicia tratamiento médico con Albendazol 400 mg por día durante 90 días, previos a la cirugía. Usamos antibiótico profilaxis con un bactericida de amplio espectro. La cirugía se realiza con el paciente en posición decúbito dorsal y con portadas: umbilical; 10mm para la óptica angulada (30-45°), epigástrico, 10 mm para el aspirador de 10mm, subcostal derecho sobre la línea medioclavicular. 5mm para aspirador de 5mm y pinzas, y subcostal derecho sobre la línea axilar anterior para pinzas. Se realiza una laparoscopía diagnóstica y reconocimiento del quiste hepático. Se introducen gasas embebidas de CINa al 21% rodeando el quiste y especialmente la parte más protuida que será la zona de trabajo. Luego se realiza la punción del quiste, tomando muestras para laboratorio en búsqueda de escólex al examen en fresco, aspiración del contenido e inyección de CINa al 21% que permanece 5 minutos, realizando estos recambios 4-5 veces. Se toma un segmento de las paredes del quiste y adventicia que va a anatomía patológica. De encontrarse la membrana germinativa e hidátides hijas, se introduce uno o más bolsas de extracción de piezas para recogerlas. Se extrae con sumo cuidado la germinativa y las hidátides hijas para colocarlas en las bolsas y aproximarlas a la portada epigástrica, para desde fuera extraer su contenido hacia un recipiente con CINa al 21%. Seguidamente se retiran una por una las gasas introducidas anteriormente, de ser posible en el interiorde una de las bolsas, se realiza la aspiración de todo líquido residual y se coloca una porción del epiplon mayor al interior de la cavidad residual, fijada al borde de la misma con puntos de sutura reabsorvible 2/0 y una sonda multifenestrada 16F que se exterioriza por una de las portadas laterales. El manejo postoperatorio es similar al de colecistectomía laparoscópica. Se reinicia la vía oral al término del ileo postoperatorio (12 a 24 horas), manejo del dolor, deambulación temprana y el alta hospitalaria depende de la persistencia del drenaje externo (48 a 72 horas).

In this paper we show the laparoscopic technique used in some patients seen by us in the last years. After we made the diagnosis, we gave medical treatment with Albendazol 400 mg per day during 90 days, prior to surgery. We also used antibiotic prophylaxis with wide spectrum antibiotics. Surgery was performed with the patient in dorsal decubitus with ports: umbilical; 10mm for angled optics (30-45°), epigastric;10mm, for right subcostal in the mid collar bone position. 5mm for aspiration and forceps and right subcostal and front axillar line. We performed a diagnostic laparoscopy to visualize the cyst. We introduced soaked gauzes with ClNa 21% surronding the cyst specially in the more protuded zone.

    1996-08-01

    A 21-year-old female American Saddle Horse with a prominent swelling on the ventral aspect of the right hemimandible and radiographic evidence of a bone cyst was examined. The cyst cavity was surgically explored and was found to contain mucinous fluid and sheets of keratin. Microscopically, the cyst was lined by well-differentiated squamous epithelium characterized by various degrees of hyperkeratosis and parakeratosis. The stromal component varied from scant areas in which epithelium was closely apposed to bone to wide regions of dense connective tissue that contained fragments of keratin surrounded by foreign-body giant cells. Histologic features were consistent with a diagnosis of intraosseous epidermoid cyst. After curettage of the cyst and repulsion of the second premolar tooth, drainage was established and iodine flushes were begun. Nine months after surgery, drainage was not detectable and size of the hemimandible had decreased by approximately a fourth. PMID:8755985

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

    Full Text Available El quiste óseo aneurismático (QOA es una lesión benigna rara en huesos maxilares, su mayor frecuencia es en huesos largos del esqueleto y columna vertebral. Algunos autores especulan que el origen sea por trauma, mala formación o un neoplasma. El aspecto radiográfico puede mostrar desde una imagen difusa hasta una imagen bien definida, muy semejante a las otras lesiones de los maxilares volviendo el diagnóstico diferencial amplio. Con la destrucción del córtex óseo puede todavía formar una imagen reaccional del periostio en forma de rayos de sol, característico de una lesión maligna. En este estudio, se presenta caso de paciente femenino, 17 años de edad, que buscó el Servicio de Cirugía y Traumatología Buco maxilofacial del Hospital São Vicente de Paulo-RS, que presentó dolor y aumento de volumen en la mandíbula. Informó que hace cerca de un año empezó a sentir malestar en la región junto al ángulo mandibular derecho, lo cual fue progresivamente aumentando de volumen. El aspecto radiográfico acordaba una lesión maligna. Después de la confirmación histopatológica de QOA, el tratamiento seleccionado para el caso fue quirúrgico conservador, con legrado de la cavidad ósea, y fue mantenido en control posoperatorio de rutina con 6 y 18 meses. En las radiografías panorámicas realizadas se verifica la neoformación ósea y cura del caso.The aneurysmal bone cyst (ABC is a benign and rare lesion in maxillary bones, is more frequent in largo bones of skeletal and spinal column. Some authors speculate about that its origin be traumatic, malformation of neoplasm. The radiographic appearance may to show from a diffuse image up to a well defined image very similar to the other maxillary lesions turning wide the differential diagnosis. With destruction of the bon cortex it is possible to create a reaction image of periosteum in sunbeams characteristic of malignant lesion. This is the case of a female patient aged 17 seeking help in the Bucco-maxillofacial Surgery and Traumatology Service of the São Vicente de Paulo Hospital _ RS, presenting with pain and an increased mandibular volume. She manifested that around one year she began to feel a discomfort next to he right mandibular angle, which was progressively increasing the volume. The radiographic appearance resembled a malignant lesion. After the histopathology verification of ABC, treatment choosed for this case was of type conservative surgical with bone cavity curettage and was maintained under systemic postoperative control for 6 and 18 months.

    Full Text Available El quiste óseo aneurismático (QOA) es una lesión benigna rara en huesos maxilares, su mayor frecuencia es en huesos largos del esqueleto y columna vertebral. Algunos autores especulan que el origen sea por trauma, mala formación o un neoplasma. El aspecto radiográfico puede mostrar desde una imagen [...] difusa hasta una imagen bien definida, muy semejante a las otras lesiones de los maxilares volviendo el diagnóstico diferencial amplio. Con la destrucción del córtex óseo puede todavía formar una imagen reaccional del periostio en forma de rayos de sol, característico de una lesión maligna. En este estudio, se presenta caso de paciente femenino, 17 años de edad, que buscó el Servicio de Cirugía y Traumatología Buco maxilofacial del Hospital São Vicente de Paulo-RS, que presentó dolor y aumento de volumen en la mandíbula. Informó que hace cerca de un año empezó a sentir malestar en la región junto al ángulo mandibular derecho, lo cual fue progresivamente aumentando de volumen. El aspecto radiográfico acordaba una lesión maligna. Después de la confirmación histopatológica de QOA, el tratamiento seleccionado para el caso fue quirúrgico conservador, con legrado de la cavidad ósea, y fue mantenido en control posoperatorio de rutina con 6 y 18 meses. En las radiografías panorámicas realizadas se verifica la neoformación ósea y cura del caso. Abstract in english The aneurysmal bone cyst (ABC) is a benign and rare lesion in maxillary bones, is more frequent in largo bones of skeletal and spinal column. Some authors speculate about that its origin be traumatic, malformation of neoplasm. The radiographic appearance may to show from a diffuse image up to a well [...] defined image very similar to the other maxillary lesions turning wide the differential diagnosis. With destruction of the bon cortex it is possible to create a reaction image of periosteum in sunbeams characteristic of malignant lesion. This is the case of a female patient aged 17 seeking help in the Bucco-maxillofacial Surgery and Traumatology Service of the São Vicente de Paulo Hospital _ RS, presenting with pain and an increased mandibular volume. She manifested that around one year she began to feel a discomfort next to he right mandibular angle, which was progressively increasing the volume. The radiographic appearance resembled a malignant lesion. After the histopathology verification of ABC, treatment choosed for this case was of type conservative surgical with bone cavity curettage and was maintained under systemic postoperative control for 6 and 18 months. In the taken panoramic radiographies is verified the bone neoformation and the cure of case.

    Full Text Available Dermoid and epidermoid cysts are benign masses that contain skin and skin attachments. They are uncommonly seen in head and neck region. They are almost seen in submental region along the midline. The most common complaint is painless swelling. Because of midline localization in the neck they can be confused with the thyroglossal cysts. In differential diagnosis, no motion with the movement of tongue is an important finding for dermoid and epidermoid cysts. In this case 50 years old female patient admitted to our clinic with submental swelling since childhood. On physical examination, we found a mass that is 3x3 cm in diameter, mobile, soft consistency, immobile with swallowing. In this study we discussed the diagnosis and treatment of mass that is totally excised and histopathologically reported as epidermoid cyst.

    Full Text Available Penile epidermoid cysts are uncommon, and a small number of cases have been reported worldwide. We present the first documented patient with a penile epidermoid cyst which consisted of multiple focuses. A 37-year-old man presented to our department with a chief complaint of an asymptomatic, soft mass in the ventral part of the penis. The mass was nontender, freely movable and measuring 3 cm within the dermis. MRI (magnetic resonance imaging revealed a high signal intensity on both T1- and T2-weighted images. Excision of the cyst was performed under local anesthesia. Macroscopically, the cut surface of the mass appeared to be full of a cheese-like material and the cyst consisted of multiple focuses. The cyst did not contain skin appendages. The pathological diagnosis was an epidermoid cyst of the penis. No recurrence has been noted in the year since the operation.

  10. Diffusion-weighted MR imaging (DWI) in two intradural spinal epidermoid cysts

    International Nuclear Information System (INIS)

    Epidermoid cysts are rare, benign, congenital, slow-growing inclusion cysts. On T1 and T2 weighted NMR images epidermoid cysts show heterogeneity and lack of contrast enhancement. Based on signal intensities on conventional sequences, epidermoid cysts cannot be distinguished from other neoplastic lesions. When located in the spinal cord, differential diagnosis includes ependymoma, astrocytoma, cavernoma and metastasis. Diffusion-weighted imaging (DWI) has been shown to accurately distinguish intracranial epidermoid tumors from arachnoid cysts. DWI findings in two patients with surgically proven epidermoid cysts in the spinal canal are reported.

    A 4-year-old Doberman Pinscher was evaluated for chronic progressive central vestibular disease and aggressiveness. A cyst-like lesion was identified in the region of the left cerebellopontine angle. The lesion was hypointense on T1-weighted and hyperintense on T2-weighted images. Differentials included an epidermoid or dermoid cyst, cystic neoplasm, and brain abscess. Hyperintensity on subsequent fluid-attenuated inversion recovery images excluded an arachnoid cyst. The histopathologic diagnosis was epidermoid cyst within the fourth ventricle. PMID:17508513

  13. Antegrade testicular vein phlebography and funicular lymphography in testicular tumors

    International Nuclear Information System (INIS)

    Antegrade phlebography of a testicular vein in connection with orchidectomy was performed in 29 patients and funicular lymphography was successful in 26 of these. Eleven patients had retroperitoneal metastases and 18 were normal. The phlebographic and lymphographic findings in both groups are described and discussed as well as the collateral pathways in cases with stenosis of the testicular vein. Antegrade phlebography is recommended but funicular lymphography does not merit a place in the routine examinations of patients with testicular tumor. (Auth.)

    2014-02-01

    Described herein are six cases of transverse testicular ectopia. All patients who underwent orchidopexy at the one pediatric surgical unit between October 2001 and January 2008 were evaluated. The medical records of all patients diagnosed with transverse testicular ectopia were evaluated retrospectively. Five patients (84%) were admitted with a symptomatic right inguinal hernia and empty scrotum on the left side. Only one child (16%) had left-sided hernia and right non-palpable testis (age ranged from 1 month to 3 years). Four patients (66%) were diagnosed in the operating theatre and the last two (33%) on inguinal ultrasound preoperatively. Magnetic resonance imaging was also performed in the last patient. Herniorrhaphy with fixation of the ectopic gonad to the opposite hemiscrotum through a transseptal incision was performed in all patients. Postoperative complications were not observed.

  20. Stage 1 testicular seminoma

    International Nuclear Information System (INIS)

    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)

    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. PMID:25949839

  10. Studies of testicular function after treatment for testicular tumor, 1

    International Nuclear Information System (INIS)

    Recently, the treatment for testicular tumor has improved. Preservation of testicular function in the treatment of testicular tumor is important, because the majority of the patients are young. We investigated the testicular function of patients with testicular tumor before, during and after treatment. As a part of this study, the fertility of patients with testicular tumor before and after treatment was evaluated. 1. Fourteen of 78 married patients (18 %) showed sterility for two or more years before treatment. 2. When semen was examined in 31 patients before treatment, only seven patients (23 %) showed normal sperm counts of more than 40 x 106/ml, and 19 (61.3 %) showed oligospermia or azoospermia with sperm counts of less than 10 x 106/ml. 3. Of 20 patients who underwent retroperitoneal lymphnode dissection, 15 developed ejaculation deficiency. Four other patients also developed ejaculation deficiency but recovered, and three of them rendered their wives pregnant. 4. Of 23 patients given radiotherapy, nine produced children both before and after treatment, nine produced children before treatment but showed sterility after treatment, and five showed sterility both before and after treatment. 5. Examination of semen was performed in 17 patients given radiotherapy and in five given chemotherapy. Many patients developed oligospermia or azoospermia after the treatments, but revealed a tendency to recover with time. Based on the results mentioned above, it is inferred that the ability to produce sperm in patients with testicular tumor after treatment decreases but the decrease tends to recover to normal with time.

  11. Recovery of testicular blood flow following ligation of testicular vessels

    International Nuclear Information System (INIS)

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

    Results: The commonest group with infertility were in the age group 21-30 years. The testicular size was normal in 87.17% of subjects and 12.82% had small testis. Out of 39 subjects with azoospermia 38.46% subjects had varicocele. Varicocele was commonly associated with duct obstruction. The commonest causes observed in cases with azoospermia were; hypospermatogenesis with maturation arrest (4/39,10.25%, duct obstruction (12/39,30.76%, maturation arrest (7/39,17.94%, testicular atrophy (10/39,25.64% and sertoli cell only syndrome (2/39,5.12%. In the present study diagnostic accuracy was 89.18%. Conclusions: Fine needle aspiration cytology is as informative as biopsy and can be done as a routine procedure. It helps us in ruling out obstructive and non-obstructive causes for azoospermia. In cases where FNAC shows normal spermatogenesis with azoospermia, biopsy and Doppler study is indicated to rule out duct obstruction which can be corrected surgically. It is a simple and cost effective. [Int J Reprod Contracept Obstet Gynecol 2015; 4(3.000: 647-652

    Full Text Available Introduction. Extradural intradiploic epidermoid cysts are rare, representing less than 0.25% of all primary intracranial tumors. They can be neurologically silent and can only present psychiatric symptoms like depression, cognitive or personality changes. Case Outline. A 68-year-old male with two year long history of depressive mood, lack of motivation, helplessness, hopelessness and poor response to antidepressive drug therapy was described. CT scan showed a well-defined mass in the parietal scalp with destruction of the scull. He underwent intracranial tumor resection. Surgical resection and cranioplasty were performed. Pathology confirmed intradiploic epidermoid cyst. Conclusion. Total removal of these cysts and repeated washing of the cavity with 0.9 % saline may prevent recurrence and aseptic meningitis and may improve mental state of the patient. We also emphasize the need for neuroimaging studies in a patient with atypical changes in mental status, even without neurological signs or symptoms.

    Epidermoid cyst is a rare, slow growing lesion of head and neck region. Its rarest site of presentation is intra-oral. It presents later in life, while taking its time to grow to a significant size, causing other complaints as dyspnoea and dysphagia. We present here a case report of epidermoid cyst at a very rare and unexpected site of presentation. Patient presented in ENT OPD with complaints of large intra-oral midline swelling and associated complaints of dyspnoea and dysphagia. Patient was admitted and operated upon with intra-oral approach, producing good results. It should be kept in mind as one of the differential diagnoses when dealing with long standing intra-oral swellings. PMID:25098100

  16. Intraosseous epidermoid cysts in the distal phalanx of two dogs

    International Nuclear Information System (INIS)

    Two dogs were presented with a history of lameness associated with swelling of one of the digits. Radiographs of the affected digits revealed an irregularly mineralized, smoothly marginated proliferative bone lesion in the distal phalanx of one dog and a destructive bony lesion in the distal phalanx of the second dog. The differential diagnosis included nail bed carcinoma, malignant melanoma, osteomyelitis, and subungual keratoacanthoma. Radiographic findings and no response to medical treatment resulted in amputation and submission of the digits for a histopathologic diagnosis. Histologic examination of the distal phalanx of the digits revealed benign epidermoid cysts associated with either bony proliferation or osteolysis. Excision of the lesions was curative. This report presents the clinical, radiographic, and histopathologic findings associated with intraosseous epidermoid cysts in the distal phalanx of two dogs

  19. Testicular Volume: Size Does Matter

    International Nuclear Information System (INIS)

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

    Full Text Available 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.

El 50% fueron diagnosticados de forma incidental y un 29% cursó con aumento de tamaño escrotal. El 46% de los casos presentaban varicocele izquierdo asociado (n=6) y un 26% presentaba antecedentes de orquiepididimitis. El diagnóstico se basó en la exploración física con confirmación ecográfica. Un 40 % fue tratado quirúrgicamente y el resto fue subsidiario de tratamiento conservador sin constatarse la presencia de complicaciones en estos en los controles posteriores. CONCLUSIONES: Dada la benignidad y la buena evolución de todos los casos de quistes de epidídimo tratados de forma conservadora, y la ausencia de beneficio con el tratamiento quirúrgico, creemos que el tratamiento debe ser conservador con controles clínicos y ecográficos reservando el tratamiento quirúrgico para aquellos quistes que presenten complicaciones. La frecuente asociación encontrada entre el quiste epididimario y el varicocele responde a una coincidencia de ambas patologías en la edad peripuberal. Abstract in english OBJECTIVES: To retrospectively review all cases of epididymal cysts registered over the last five years; 15 cases have been included.

(1-16). 50% were diagnosed incidentally and 29% presented increased scrotal size. 46% of the cases had associated left varicocele (n = 6) and 26% had history of orchiepididymitis. Diagnosis was based on physical examination and confirmed by ultrasound. 40% of the patients underwent surgery and the remainder received conservative treatment without evidence of complications on follow-up. CONCLUSIONS: Due to the benign character and good evolution of all cases of epididymal cysts treated conservatively and the absence of benefit after surgical treatment, we believe that management should be conservative with clinical and ultrasound controls, leaving surgery for cysts with complications. The frequent association between epididymal cysts and varicocele is related to coincidence of both pathologies in the prepuberal age.

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

  11. A giant testicular teratoma

    International Nuclear Information System (INIS)

    We report a giant testicular in a 36-year-old farmer man, of 18-month duration admitted to the Surgical Department Erbil Teaching Hospital, Iraq. The tumor was invading the penis and lower part of abdominal wall including bilateral groin lymph nodes. Histological examination revealed mature and immature teratoma. Further investigations showed no evidence of any metastatic lesions apart from a solitary pulmonary nodule on the right side of the chest which proved by ultra sonic guide fine needle aspiration biopsy. Radical excisions of the tumor including the shaft of the penis, combined with bilateral block dissection of the inguinal nodes and resection of the lower anterior abdominal wall was performed. Six weeks later after a course of chemotherapy and radiotherapy, the patient underwent resection of metastatic lung lesion. (author)

    Full Text Available INTRODUÇÃO: A ectopia testicular cruzada (ETC) é uma anomalia rara, caracterizada pela descida de um testítulo no canal inguinal do lado oposto. Apresentamos um caso de ectopia cruzada do testículo direito, tratado por transposição extraperitoneal da gônada e orquipexia direita. CONCLUSÃO: Os conhec [...] imentos embriológicos e os achados cirúrgicos sugerem que a ETC seja uma conseqüência comum de vários fatores etiológicos, sobretudo fatores mecânicos, e pode causar persistência do ducto de Müller. Após extensa revisão da literatura,sugerimos uma classificação da ETC em 3 tipos: 1 - associada somente à hérnia inguinal; II associada a remanescentes mullerianos; III - associada a outras anomalias, sem remanescentes mullerianos. O tratamento inclui orquipexia trans-septal ou transposição trans-abdominal do testículo, pesquisa de remanescentes mullerianos e outras anomalias, e seguimento pós-operatório a longo prazo, devido a risco de malignização. Abstract in english Crossed testicular ectopia (CTE) is a rare anomaly, characterized by migration of one testis towards the opposite inguinal canal. 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 findi [...] ngs 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.

Mat [...] erial y método. Entre 1999 y 2004, cinco pacientes con QGP sintomáticos, con o sin hidrocefalia, se trataron mediante vintriculostomía premamilar endoscópica (VPE) y fenestración del quiste. Se utilizó un endoscopio rígido, con sistema de neuronavegación en los casos sin hidrocefalia. Resultados. En el período de seguimiento (de 6 meses a 4 años) se recoge una resolución clínica en 4 casos y una disminución del tamaño del quiste en todos los casos. Todas las VPE fueron permeables en el seguimiento. No hubo déficits clínicos permanentes en ningún caso. Discusión. No existe en la literatura un acuerdo en el mejor tratamiento quirúrgico de los QGP. A pesar de la gran aceptación de la vía endoscópica, un gran número de autores abogan por una cirugía abierta o por una cirugía extereotáxica como la mejor opción. Además, existen algunas diferencias en el manejo quirúrgico endoscópico según ofrece la literatura. Conclusión. La VPE con la fenestración del quiste es un tratamiento eficiente debido a la baja morbilidad y a la eficacia en la resolución clínica y radiológica de los QGP con o sin hidrocefalia. La cirugía abierta, especialmente con la ayuda endoscópica, podría ser un tratamietno de segunda elección, y la cirugía estereotáxica debería abandonarse en estos casos. Abstract in english Objetive.

Between 1999 and 2004, five patients with GPC underwent an endoscopic third ventriculostomy (ETV) and cyst fenestration. We have used a rigid endoscope, with neuronavegation system in the cases without hydrocephalus. Results. In the follow-up period ranged from 6 months to 4 tears we have reported: clinical resolution in four cases and cyst size decrease in all cases. All the ETV have been patent. There was not perman ent morbility and not surgery related death. Discussion. An agreement doesn't exist in the literature about the better treatment of the surgery or by stereotaxy as the best treatment. There are great differences in the surgical management between the 18 endoscopic cases reported in the literature, and also in relation with our cases. Conclusion. The ETV with endoscopic cyst fenestration is an efficient treatment due to the low morbidity and the effectiveness in the treatment of the GPC with or without hydrocephalus. The open surgery (specially with the endoscope assisting microneurosurgery) wolud be a second choice technique, and the stereotactic surgery must be abandoned.

  8. MR imaging in the evaluation of epidermoid cysts and cholesterol granulomas of the posterior fossa

    International Nuclear Information System (INIS)

    This paper reports on MR imaging and CT examination of ten patients with epidermoid cysts and six patients with cholesterol granulomas of the cerebellopontine region. MR imaging proved superior to CT for the assessment as well as differentiation of these lesions. Most epidermoid tumors had long T1 and long T2 signal characteristics. Cholesterol granulomas, except one case, demonstrated short T1 and long T2 signal characteristics. Short-repetition time, short TE-echo time, MR images with maximum excitations (eight) showed characteristic serpiginous structures in epidermoids that were thought to be due to macromolecule of the keratin in keratoma. In two epidermoid cysts, in vivo H-1 spectroscopy was performed. The spectra of these cysts did not show any specific resonance marker related to keratin or lipid

    Spinal epidermoid cysts occur as a result of anomalous implants of epidermal cells within the spinal cord. Spinal epidermoid cysts comprise < 1% of all intraspinal mass lesions and may be congenital or acquired. Congenital lesions usually occur at conus or cauda equina, and the latter usually occur at lower lumbar spine. The typical MR appearance of a spinal epidermoid cyst is a hypointense signal lesion on T1-weighted images and a hyperintense signal lesion on T2-weighted images. However, atypical imaging features also have been reported. In this article, we report atypical MR findings of an intradural epidermoid cyst at conus medullaris and cauda equina of the spine that was caused by internal cystic hemorrhage.

  11. Neuroroentgenologic diagnosis of epidermoid and dermoid tumors with intracranial and intraspinal localization

    International Nuclear Information System (INIS)

    The value and the possibilities of several X-ray diagnostic methods and the pathologic lesions detected by them in 15 patients with intracranial and intraspinal epidermoid and dermoid tumors have been analysed. Computerized tomography (CT) is considered as a basic and highly effective method for diagnosis of tumors with intracranial localization. The most important CT symptoms were: well outlined low density zones (CSF equivalent in the epidermoids and lipid equivalent in the dermoids), dislocation, peripheral calcificates in dermoids, absence of intravenous contrast intensification. Pneumocysternal CT of epidermoids located in pars petrosa helps to evaluate tumor expansion in cisterna pontis lateralis. The use of brain angiography should be limited because of inability to provide specific diagnostic information. CT myelography following conventional myelography with water soluble contrast nonionizing compounds, in addition to its ability to define the exact localization of the process, essentially contributes to the preoperative specific diagnosis of epidermoid and dermoid tumors with intraspinal localization. 5 figs., 1 tab., 16 refs

  15. Diffusion tensor mode in imaging of intracranial epidermoid cysts: one step ahead of fractional anisotropy

    International Nuclear Information System (INIS)

    The signal characteristics of an epidermoid on T2-weighted imaging have been attributed to the presence of increased water content within the tumor. In this study, we explore the utility of diffusion tensor imaging (DTI) and diffusion tensor metrics (DTM) in knowing the microstructural anatomy of epidermoid cysts. DTI was performed in ten patients with epidermoid cysts. Directionally averaged mean diffusivity (Dav), exponential diffusion, and DTM-like fractional anisotropy (FA), diffusion tensor mode (mode), linear (CL), planar (CP), and spherical (CS) anisotropy were measured from the tumor as well as from the normal-looking white matter. Epidermoid cysts showed high FA. However, Dav and exponential diffusion values did not show any restriction of diffusion. Diffusion tensor mode values were near -1, and CP values were high within the tumor. This suggested preferential diffusion of water molecules along a two-dimensional geometry (plane) in epidermoid cysts, which could be attributed to the parallel-layered arrangement of keratin filaments and flakes within these tumors. Thus, advanced imaging modalities like DTI with DTM can provide information regarding the microstructural anatomy of the epidermoid cysts. (orig.)

Testicular lymphoma and carcinoma cannot be distinguished using FDG-PET thus emphasizing the principle that FDG-PET should be used as a tool for staging, not for primary diagnosis and that the nature of the pathological condition causing FDG uptake has to be confirmed with biopsy/histology Copyright (2006) Blackwell Publishing Asia Pty Ltd

    Epidermoid cysts are histologically benign, slow-growing congenital neoplasms of the central nervous system that may arise from retained ectodermal implants. The epidermoid lesions are generally caused during the 3rd to 5th week of gestation by an incomplete cleavage of the neural tissue from the cutaneous ectoderm, though it can also happen later in life due to introduction of skin elements by skin puncture, trauma or surgery. We present this unique case of a petromastoid epidermoid cyst ass...

La paciente de 11 años consultó, al servicio de urgencia por un dolor abdominal agudo que hizo plantear clínicamente la existencia de una apendicitis aguda. La identificación de un apéndice y ovarios normales, junto al hallazgo de una estructura quística compleja próxima al ovario llevaron a la cirugía laparoscópica que identificó la hidátide torcida a derecha y una estructura quística similar no torcida a izquierda. Se discute esta patología como una eventual y rara causa de dolor abdominal agudo en el sexo femenino: We report the ultrasonographic and laparoscopic findings in a case of twisted parovarian cyst related with a Morgagni hydatid, without involving of the tube and ovary. The 11 years old patient consulted for an acute abdominal pain that made suspect the clinical existence of acute appendicitis. The identification of normal appendix and ovaries, and the finding of a complex cyst structure close to the ovary, led to the laparoscopic surgery, that identified a twisted hydatid at the right side and a non twisted cystic structure at the left side.

    We describe a pulmonary metastasis from a laryngeal epidermoid carcinoma, characterized by an interstitial pattern of growth. The patient, a 71-year-old man, smoker, presented with a large laryngeal neoplasm and with two pulmonary masses, one located in the apex and the other in the lower lobe of the right lung. The patient underwent a total laryngectomy and a right pneumonectomy and he died from neoplastic progression 2 years after surgery. Microscopically, the laryngeal tumour was an epidermoid carcinoma and the apical pulmonary mass was an adenocarcinoma. The pulmonary neoplasm of the lower lobe, 5.5 cm across, was an epidermoid carcinoma that we interpreted to be a metastasis from the larynx. The case is peculiar because tumour cells proliferated exclusively in the interstitium. When extensive as in our case, this pattern of growth is rare and it may pose some diagnostic problems.

    Intracranial epidermoid cysts usually show homogeneous hypodensity on CT scans, hypointensity on T1-weighted MR images and hyperintensity on T2-weighted MR images. Most of them arise in the cerebellopontine angle and parasellar areas. We report a case of middle cranial fossa epidermoid tumor with unusual image findings. The entire tumor mass showed inhomogeneous low density, without any enhancing solid portion on the CT scans. The lateral portion of the tumor showed homogeneous T1 low signal intensity and T2 high signal intensity. The medial portion of the tumor showed heterogeneous T1 and T2 intermediate to high signal intensity. On the gadolinium enhanced MR images, enhancement of the thickened dura was observed behind the tumor. Surgery and pathologic examination revealed the presence of an extradural epidermoid cyst.

El diagnóstico se realiza a través de la ecografía abdominal y se completa con una colangio-pancreatografía por resonancia magnética. El tratamiento recomendado es la resección quirúrgica completa que previene la aparición de complicaciones. Estos pacientes deben ser valorados periódicamente por el riesgo de malignización que presentan, incluso luego de la cirugía. Se presenta el caso clínico de un lactante de 3 meses que, en el curso de una enfermedad febril aguda, presentó signos de obstrucción biliar parcial, diagnosticándose un QC fusiforme con probable colangitis. Se inició tratamiento antibiótico empírico, con buena evolución.

It is diagnosed in most cases during early childhood, although it can occur at any age of life. The clinical presentation is variable, and can manifest itself through abdominal [...] pain, palpable mass and cholestatic jaundice, or symptoms related to the development of some of its complications: pancreatitis, cholangitis or rupture. The diagnosis is made through an abdominal ultrasound and is completed with a colangio- pancreatography by magnetic resonance imaging. The recommended treatment is complete surgical resection, which prevents the appearance of complications. These patients should be evaluated regularly for the risk of malignancy, even after the surgery. The clinical case that is presented is of an infant of three months, who in the course of an acute febrile illness presented signs of partial biliary obstruction, and was diagnosed with a fusiform QC with likely cholangitis. Empirical antibiotic treatment, with good evolution began. It draws attention to the unusual presentation of this malformation of bile duct in infants, which requires surgery for its definite treatment

    Full Text Available The paraurethral or Skene’s duct cyst, is a rare diagnostic entity in a newborn. It represents less than 0,5 % of congenital malformations of the urinary tract. All over the world it is reported an incidence of 1:2000 to 1:7000 in female births. In the newborn, the paraurethral cyst is caused by retention of secretions in the Skene's gland due to the obstruction of its ducts. Most of these cysts decrease in size during the first four to eight weeks, but they may cause symptoms of infection or urinary obstruction. They can also get formed from persistent embryonic remains of the mesonephric ducts (Wolffian duct, known as Gartner cysts and from the occlusion of unfused paramesonephric ducts (Müllerian. The case of a 25-day-old female, diagnosed with paraurethral cyst that underwent surgery and evolved successfully is presented.El quiste parauretral o de Skene, es una entidad de diagnóstico muy raro en el recién nacido, representa menos del 0,5 % de las malformaciones congénitas de las vías urinarias. Se reporta mundialmente una incidencia de 1:2000 a 1:7000 en los nacimientos femeninos. En la recién nacida, el quiste parauretral se origina por la retención de secreciones en la glándula de Skene, debido a la obstrucción de sus conductos. La mayoría de estos quistes disminuyen de tamaño durante las primeras cuatro a ocho semanas, pero pueden presentar síntomas de infección u obstrucción urinaria. También se pueden formar a partir de restos embrionarios persistentes de los conductos mesonéfricos (conductos de Wolf, llamados quistes de Gartner y de la oclusión de los conductos paramesonéfricos no fusionados (Müllerianos. Se presenta el caso de una paciente de 25 días de nacida, de sexo femenino, que se le diagnosticó un quiste parauretral y se le realizó tratamiento quirúrgico, del cual evolucionó de manera satisfactoria.

    Full Text Available Los huesos maxilares constituyen asiento de una gran variedad de quistes y neoplasias que pueden ser de difícil diagnóstico. De entre todos los procesos tumorales que se dan en el territorio maxilofacial, los quistes son de gran importancia debido a la frecuencia de su presentación. Los quistes maxi [...] lares tienen distinto origen y comportamiento clínico. A partir de la clasificación de la OMS de 1992, esta revisión estudia las características clínicas, radiográficas y epidemiológicas de los quistes del desarrollo odontógenos. Una adecuada exploración clínica y radiográfica por parte del odontólogo es suficiente para alcanzar un diagnóstico de presunción. Las consideraciones clínicas y terapéuticas de cada uno de estos quistes son variables, por lo que es necesario conocer el comportamiento epidemiológico de ellos. El diagnóstico de presunción, el tamaño de la lesión y la relación de esta con estructuras anatómicas vecinas condicionará el tipo de tratamiento. El diagnóstico definitivo lo dictaminará el análisis anatomopatológico. Abstract in english The maxillary bones constitute the base of a big variety of cyst and tumours that can be difficult to diagnose.

A [...] fter the OMS classification in 1992, this review examines the clinical, radiographic and epidemiological characteristics of the cyst of the odontogenic development. An appropriate clinical and radiographic exploration on the part of the dentist is enough to reach a presumptive diagnosis. The clinical and therapeutic considerations of each of these cysts are variable, so it is necessary to know their epidemiological behavior. The presumptive diagnosis, the size of the cyst and its relationship with neighboring anatomical structures will determine the type of treatment. The definitive diagnosis will be determined by the anatomical and pathological diagnosis.

    1987-01-01

    Experimental testicular torsion must be used for certain studies of clinical relevance, but most experimental models either do not provide hemodynamic alteration comparable to the clinical situation or cannot guarantee reproducibility. Using a rat model arterial perfusion and hemorrhagic infarction were correlated to the degree of both intra- and extravaginal testicular torsion. Arterial inflow was measured sequentially with radiolabelled microspheres, hemorrhagic infarction was judged by the increase of testicular weight. Maximal hemorrhagic infarction and reproducible values were found when the spermatic cord was twisted together with the tunica vaginalis for 360 degrees-540 degrees. PMID:3686761

La diseminación más común es en sentido ascendente por extensión en la mucosa y fácilmente se extiende a través de la pared esofágica a estructuras adyacentes, debido a la ausencia de serosa. Las mayores complicaciones son atribuidas a la obstrucción luminal y la invasión local. Presentamos un caso de un paciente de 69 años de edad. La endoscopia digestiva superior evidenció dos lesiones separadas en esófago distal y fundus gástrico. Los cambios histológicos determinaron que ambas lesiones eran carcinoma epidermoide.

The disease predominantly affects the elderly with a peak incidence among those between 60 and 70 years of age. Unfortunately, many of the symptoms experienced by patients with esophageal cancer occur la [...] te in the course of the disease, at which time it is already at an advanced stage, resulting in a very poor prognosis. The most common dissemination is in an ascending path through mucosal extension; extending easily through the thin esophageal wall due to the absence of a serosa to invade adjacent structures. Most complications due to esophageal cancer are attributed to luminal obstruction and local invasion. A case of a 69-year-old male patient is presented. Upper digestive endoscopy showed two separated lesions at the distal esophagus and gastric fundus. Histological changes showed both lesions were squamous cell carcinomas.

    Despite the prompt diagnosis and treatment of testicular torsion (TT), there are problems with fertility and atrophy after testicular salvage. Dexpanthenol (Dxp) is the biologically active alcohol of pantothenic acid (PA). Dxp is converted to PA in tissues. PA increases the content of reduced glutathione (GSH), Coenzyme A and ATP synthesis in cells. GSH and glutathione-dependent peroxidases (GPX) are the major defense systems against oxidative stress. GPX-4 is the major antioxidant in testicular tissue. However, the activity of GPX-4 appeared and increased only after puberty. We investigated the effect of Dxp on testicular atrophy after TT at the 60th day. Rats were separated randomly into four groups. Group C: control group, group Td: torsion + detorsion, group Sal: torsion + saline + detorsion, group Dxp: torsion + Dxp + detorsion. The left testis was rotated 720 degrees for 2 h. In group Sal, normal saline and in group Dxp, Dexpanthenol were injected intraperitonally, 30 min before detorsion. After 60 days, the testicular weights and volumes were measured. Histopathology of the left testis was evaluated with mean seminiferous tubular diameter (MSTD) and mean testicular biopsy score (MTBS). The left (torsed) testicular weight and volume of groups Td and Sal were significantly lower compared to group Dxp. The MSTD and MTBS of group Td and Sal were significantly lower than group Dxp. Contralateral testicular weight and volume of groups Td, Sal and Dxp had no significant difference compared to the control group. Dxp significantly prevented testicular atrophy after 60 days of TT. Dxp has FDA approval, is safe, cost effective and readily available. Its relevance for clinical trials may especially be for the problem of testicular atrophy catastrophe, seen very frequently following testicular salvage. PMID:17205291

  15. Histological evidence of testicular dysgenesis in contralateral biopsies from 218 patients with testicular germ cell cancer

    DEFF Research Database (Denmark)

    Hoei-Hansen, Christina E; Holm, Mette

    2003-01-01

    This study was prompted by a hypothesis that testicular germ cell cancer may be aetiologically linked to other male reproductive abnormalities as a part of the so-called 'testicular dysgenesis syndrome' (TDS). To corroborate the hypothesis of a common association of germ cell cancer with testicular dysgenesis, microscopic dysgenetic features were quantified in contralateral testicular biopsies in patients with a testicular germ cell tumour. Two hundred and eighty consecutive contralateral testicular biopsies from Danish patients with testicular cancer diagnosed in 1998-2001 were evaluated retrospectively. Two hundred and eighteen specimens were subsequently included in this study, after 63 patients who did not meet inclusion criteria had to be excluded. The presence of carcinoma in situ (which is believed to originate from transformed gonocytes) was detected in 8.7% of biopsies. The incidence of other dysgenetic features was immature tubules with undifferentiated Sertoli cells, 4.6%; microcalcifications (microliths), 6.0%; and the presence of a Sertoli-cell-only pattern in at least a few tubules, 13.8%. The cumulative incidence of one or more signs of testicular dysgenesis was 25.2%. In a few patients, areas with immature and morphologically distorted tubules were also noted. Spermatogenesis was qualitatively normal in 51.4%, whereas 11.5% had very poor or absent spermatogenesis. It is concluded that microscopic testicular dysgenesis is a frequent feature in contralateral biopsies from patients presenting with testicular germ cell neoplasms of the adolescent and young type. The findings therefore support the hypothesis that this cancer is part of a testicular dysgenesis syndrome. The presence of contralateral carcinoma in situ was higher in the present study than previously reported.

  16. Transverse testicular ectopia - case report

    Živanovi? Dragoljub

    2004-01-01

    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.

  17. Testicular blood flow in varicocele

    International Nuclear Information System (INIS)

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

    2009-01-01

    Cadmium (Cd) is an environmental toxicant and an endocrine disruptor in humans. Several organs (e.g., kidney, liver) are affected by Cd and recent studies have illustrated that the testis is exceedingly sensitive to Cd toxicity. More important, Cd and other toxicants, such as heavy metals (e.g., lead, mercury) and estrogenic-based compounds (e.g., bisphenols) may account for the recent declining fertility in men among developed countries by reducing sperm count and testis function. In this review, we critically discuss recent data in the field that have demonstrated the Cd-induced toxicity to the testis is probably the result of interactions of a complex network of causes. This is likely to involve the disruption of the blood-testis barrier (BTB) via specific signal transduction pathways and signaling molecules, such as p38 mitogen-activated protein kinase (MAPK). We also summarize current studies on factors that confer the testis sensitivity to Cd, such as Cd transporters and metallothioneins, and the impact of Cd on the testis as an endocrine disruptor, oxidative stress inducer and how it may disrupt the Zn+2 and/or Ca+2 mediated cellular events. While much work is needed before a unified mechanistic pathway of Cd-induced testicular toxicity is emerged, recent studies have helped to identify some of the likely mechanisms and/or events that take place during Cd-induced testis injury. Furthermore, some of the recent studies have shed lights on potential therapeutic or preventive approaches that can be developed in future studies by blocking or minimizing the destructive effects of Cd to testicular function in men.

    Full Text Available Testicular cancer is one of the commonest cancers in men of working age, and is increasing in incidence in Europe and North America. One suggested mechanism of causation is that there is impaired differentiation of germ cells in the pre- or perinatal period, followed by malignant transformation in later life, possibly by a hormonal mechanism. Endocrine disrupting chemicals (EDCs have been a major focus of interest for etiological research into testicular cancer because they interact with various hormonal pathways. Several EDCs including bisphenol A, phthalates, metals, polychlorinated biphenyls, and organochlorines have been investigated, but there are few studies and those that exist have not been able to assess exposure well. In addition, several studies, particularly those with better exposure assessment, have suggested that workers in electrical occupations have increased risks of testicular cancer. Electromagnetic radiation may have subthermal effects or may disrupt hormone release. Chronodisruption such as due to shift-work could potentially increase the risk of testicular cancer via disruption of hormonal cycles, but only one study has so far investigated this possibility. Lastly, solvent exposure, particularly to dimethylformamide, has been suggested to be associated with testicular cancer, but almost all these studies are based on job title only, with no specific assessment of solvent exposure. In conclusion, there is little evidence available on which to base definitive statements about occupational causes of testicular cancer. Future studies need to improve exposure assessment and develop ways to adjust for possible prenatal factors.

El quiste residual puede haber sido anteriormente un quiste lateral o un quiste apical y al haberse extraído el diente, a partir de cuyo periodonto se forma el quiste, se queda en el tejido óseo sin haber sido extirpado. Objetivo: presentar un caso al cual se le diagnosticó y trató un quiste residual mandibular que abarcaba la hemiarcada izquierda, que permitió restablecer las funciones masticatorias y estética. Caso Clínico: paciente que fue atendido en la consulta de Cirugía Maxilofacial de la Facultad de Estomatología de Camagüey, con un aumento de volumen en la región lateral izquierda, con antecedentes de trauma anterior que le provocó fractura de mandíbula. Se describen las características clínicas de la enfermedad y el tratamiento quirúrgico realizado, se utilizó para el mismo los principios de la técnica de enucleación. Conclusiones: aunque se han reportados pocos casos en la literatura nacional y extranjera, estos han sido quistes de menor tamaño que incluyen uno o dos dientes, no existen reportes de quistes residuales que involucren toda la arcada o hemiarcada dentaria. Se obtuvieron resultados estéticos satisfactorios con la técnica quirúrgica empleada y no se presentaron complicaciones. Abstract in english Background: a cyst is a structure with a tendency to be rounded, made up of an external wall of fibrous connective tissue, an internal wall composed of epithelial tissue. The cystose cavity contains sallow liquid or semiliquid material that, when becomes infected, gets purulent and brown. A residual [...] cyst could have been previously a lateral cyst or an apical cyst and when the tooth is extracted from the periodontium, the cyst remains in the osseous tissue without being removed. Objective: to present a case diagnosed and treated for a mandibular residual cyst that extended over the left hemiarcade. It was possible to re-establish the masticatory and aesthetic functions. Clinical case: a patient who was treated in the Maxillofacial Surgery consultation of the Faculty of Stomatology of Camagüey. The patient presented a volume increase in the left lateral region and an antecedent of front trauma that caused fracture of the lower jaw. The clinical characteristics of the disease and the surgical treatment conducted are described. The principles of the enucleation technique were used for conducting the surgical treatment. Conclusions: in spite of the fact that few cases have been reported in the national and foreign literature, these have been smaller cysts that included one or two teeth. There are no reports of residual cysts that extend over all the dental arcade or hemiarcade. Satisfactory aesthetic results were obtained with the surgical technique applied and there were no complications.

    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 se [...] lf-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.

Ocho (85,6% embarazadas, ingresaron por dolor abdominal agudo. Otro caso ingresó a cirugía electiva por quiste ovárico persistente. Los quistes tenían entre 6 y 13 cm. En 5 se realizó sólo destorsión ovárica, en 1 ooforectomía y en 1 quistectomía. Se realizó punción, destorsión y fijación a ligamento útero ovárico, bilateral, en la otra paciente. Se registró un caso de fiebre en el postoperatorio. El alta hospitalaria fue a las 48 horas en 6 (67%, a las 72 en 2 y a las 96 en 1. El estudio biópsico diferido en 3 pacientes demostró: 1 quiste seroso paratubario, 1 quiste luteínico parcialmente hemorrágico y 1 infarto anexial. Todos los embarazos evolucionaron normalmente. Conclusión: Nuestra experiencia confirma que en el embarazo la laparoscopía es una buena opción al requerir una cirugía por quiste anexial complicado o persistente.Background: Recent reviews show an increase in the finding of adnexal cysts during pregnancy.

Las variedades anatomopatológicas más importantes son: el carcinoma epidermoide, el adenocarcinoma y el sarcoma primarios. Analizamos nuestra experiencia en este tipo de tumores. MATERIAL Y MÉTODOS: Estudio retrospectivo de los tumores vesicales inusuales tratados en nuestro Hospital entre 1988- 2001. Analizamos su comportamiento biológico y tratamiento aplicado. En todos ellos se descartó el origen extravesical de la tumoración. RESULTADOS: Encontramos 21 casos, cuyas variedades anatomopatológicas fueron: 13 Carcinomas Epidermoides, 7 Adenocarcinomas (3 de Uraco) y un Sarcoma. La edad media fue muy diferente entre los carcinomas epidermoides (69,2 ± 9,1 años) y los adenocarcinomas (50,3 ± 8,1). En las tres variedades histológicas el comportamiento fue muy agresivo. En el momento del diagnóstico 19 pacientes presentaban estadios locales avanzados (?T2). Aunque el tratamiento electivo fue la cistectomía, sólo se pudo realizar en 10 casos. Quimioterapia sistémica (la más frecuente M-VAC) y/o RT local se aplicó en 7 casos. 14 pacientes han fallecido, con una supervivencia media de 15,7 ± 11,6 meses. CONCLUSIONES: El diagnóstico tardío de estos tumores y su agresivo comportamiento biológico comportan un pronóstico sombrío. Sólo un diagnóstico precoz y un tratamiento radical podrían mejorar su pronóstico. Abstract in english INTRODUCTION AND OBJECTIVES: Non-transitional cell tumours of the bladder are both a diagnostic challenge for the pathologist and a therapeutic challenge for the urologist, because although uncommon (less than 5% of all malignancies of the bladder) they show different biological behaviours each requ [...] iring a unique approach. The most significant pathoanatomical types are: primary epidermoid carcinoma, primary adenocarcinoma and primary sarcoma. This paper presents an analysis of our experience in these types of tumours. MATERIAL AND METHODS: A retrospective study of unusual cases of cancer of the bladder seen in our hospital between 1988-2001. Their biological behaviour and the therapies applied are analysed. The extravesical origin of the tumour was ruled out in all cases. RESULTS: We found 21 cases of the following pathoanatomical varieties: 13 epidermoid carcinomas, 7 adenocarcinomas (3 urachal) and 1 sarcoma. Mean age was very different between epidermoid carcinomas (69.2 ± 9.1 years) and adenocarcinomas (50.3 ± 8.1). Tumour behaviour was very aggressive in all three histological varieties. At the time of diagnosis 19 patients had locally advanced stages (?T2). Although elective therapy was cystectomy, this was only feasible in 10 cases. Systemic chemotherapy (most frequently M-VAC) and/or local radiotherapy was used in 7 cases. 14 patients have died after a mean survival of 15.7 ± 11.6 months. CONCLUSIONS: Late diagnosis of these tumours and their aggressive biological behaviour involve a gloomy prognosis. Only early diagnosis and radical therapy could improve the prognosis.

    Full Text Available Los quistes cutáneos son patologías frecuentes en la práctica dermatológica. Tienen etiologías variadas, y aunque la mayoría son adquiridos también pueden representar un fenómeno determinado genéticamente. Pueden ser esporádicos o aparecer de forma familiar. Son clínicamente fáciles de diagnosticar como ?quistes?, pero el diagnóstico de certeza es estrictamente anatomo-patológico, ya que los mismos se nombran por el tipo de epitelio que los reviste, los elementos que se observan en sus paredes y en su interior. Los pacientes con quistes consultan por preocupaciones cosméticas o debido a las molestias de la irritación mecánica o inflamación del quiste. Las lesiones pueden ser proliferantes e incluso pueden desarrollarse tumores a partir del epitelio. Hacemos una breve revisión de los quistes y pseudoquistes cutáneos más importantes y presentamos tres casos clínicos.....Skin cysts are common conditions in dermatology practice. They have varied etiologies, and while most are acquired they may also represent a genetically determined phenomenon. They can be sporadic or familial. They are easily diagnosed clinically as ?cysts?, but the definitive diagnosis is strictly pathological, since they are named for the type of epithelial lining, the elements seen in the walls and the elements inside. Patients with cysts consult for cosmetic concerns and for inconvenience caused by mechanical irritation or inflammation of the cyst. The lesions may proliferate and even tumors may develop from the epithelial coating. We briefly review the most important skin cysts and pseudocysts and present three clinical cases.

  9. Ultrasonographic diagnosis of torsion of testicular appendages

    International Nuclear Information System (INIS)

    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

    Full Text Available Objetivo: Se presenta un nuevo caso de infarto segmentario de testículo. Métodos: Paciente de 52 años que solicitó valoración por dolor en hemiescroto izquierdo de varios días de evolución. En la exploración física presentaba una induración palpable, dolorosa al tacto, en el polo superior del testíc [...] ulo izquierdo. Los marcadores tumorales (beta-hCG y alfa-fetoproteína) fueron normales. En el estudio ultrasonográfico se apreció una lesión nodular hipoecogénica intratesticular izquierda de 13 mm de diámetro, de bordes ligeramente irregulares, que no mostraba flujo en el análisis con Doppler color. Resultados: Con el diagnóstico de tumoración testicular izquierda se realizó orquiectomía por vía inguinal. Al corte dicha induración se correspondía con un nódulo bien delimitado. El estudio histopatológico mostró que la lesión correspondía a un infarto testicular segmentario, sin evidencia de malignidad ni signos de vasculitis. Conclusiones: La forma más habitual de diagnóstico del infarto segmentario de testículo se produce durante el estudio histopatológico de las piezas de orquiectomía radical realizadas por sospecha de tumor. La ultrasonografía con Doppler y la resonancia magnética nuclear tienen alta habilidad diagnóstica, si bien puede resultar difícil descartar categóricamente un tumor de testículo. En estos casos se puede recurrir a la exploración con biopsia que confirme la lesión isquémica no tumoral. Abstract in english Objective: A new case of segmental testicular infarction is reported. Methods: A 52-year-old man presented to the emergency department with severe pain in the left testicle over a few days period. Physical examination revealed a tender induration in the upper pole of the left testicle. [...] mbol>beta-human chorionic gonadotropin and alpha-fetoprotein were normal. Sonography demonstrated a poorly-defined, hypoechoic, 13 mm lesion. On power Doppler sonography, the hypoechoic area appeared completely avascular in contrast to the rest of the testicle. Results: Since testicular tumor was the initial diagnosis, the patient underwent a left radical orchiectomy. Pathological study revealed a focal testicular infarction, without signs of malignancy or vasculitis. Conclusions: Segmental testicular infarction is usually diagnosed after radical orchiectomy, performed when testicular tumor is suspected. On certain occasions Doppler ultrasound and magnetic resonance imaging findings suggested a segmental testicular infarction. However, if tumor cannot be entirely excluded, exploratory surgery is necessary.

    Epidermoid cysts are a rare entity in the oral cavity and are even less frequent in the floor of the mouth, representing less than 0.01% of all the cases. We present the case of a 3-year-old girl with a growth in the floor of the mouth with 2 months of evolution and without changes since it was discovered by her parents. The lesion was asymptomatic; it did not cause dysphagia, dyspnea, or any other alteration. A CT scan with contrast was done which revealed the location and exact size of the lesion, allowing an intraoral approach for its excision. The histological examination confirmed the clinical speculation of an epidermoid cyst. PMID:25694831

    Full Text Available The frequency of distant metastasis of epidermoid carcinoma of the larynx is between 6.5-7.2%. The common sites of metastasis are lung, liver and bone. Cutaneous metastasis is very rare. A 56-year-old male with locally advanced larynx carcinoma who received curative radiochemotheraphy a year ago was presented to our department with subcutaneous nodular lesions, and fatigue. Physical examination revealed 0.5 cm sized, and 1x1cm sized subcutaneous nodular lesions in the right arm, and in the parasternal area, respectively. Histopathologic examination confirmed the skin metastasis of epidermoid carcinoma of the larynx. The patient has profound anemia, hypercalcemia, hypernatremia, and hyperglicemia with complicated diabetic foot. Although the symptomatic treatment began immediately, the patient died on the third day of hospitalisation. Cutaneous metastasis may be the first sign of local failure, of distant metastasis, or even of the undetected laryngeal carcinoma with poor prognosis.

    Intracranial chordomas, originating from remnants of the primitive notochord, are extradural tumors arising mostly at the sphenooccipital synchondrosis in the clivus. We present an unusual case of intradural chordoma at the prepontine cistern, with parenchymal compressive invasion to the pons. It was excised subtotally, followed by a second operation due to the increasing remnant tumor size during 8 months. A differential diagnosis for intradural chordoma must be considered when the preoperative MRI features are not consistent with an epidermoid cyst if there are multiple fine enhancing lesions on enhanced magnetic resonance images and no bright signal intensity on diffusion weighted images. This report is concerned with the radiological findings in the intradural chordoma and the differential diagnosis focused on the epidermoid cyst.

    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.

    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 (100?110mm 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 (120?110mm. She had severe pain accompanied with anorexia and vomiting. Fetus was normal in sonography. Exploratory laprotomy with splenectomy was performed. Splenomegaly (200?130?90mm with a cyst without any adhesion and inflammation was detected. Histopathology examination showed epidermoid cyst of spleen. (140?10?90mm. 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.

  19. Evaluation of radiotherapy and chemoradiotherapy for anal canal epidermoid cancer in our center

    International Nuclear Information System (INIS)

    The efficacy and safety of radiotherapy (RT) and chemoradiotherapy (CRT) for anal canal epidermoid cancer were evaluated. Twenty-four patients with anal canal epidermoid cancer were treated in our center between 1988 and 2006, consisting of 13 patients treated by RT and 11 by CRT. In these patients, the efficacy and safety of RT and CRT were evaluated in terms of adverse events, 5-year local control rates, 5-year disease-free survival rates, and 5-year survival rates. No grade 3 or higher adverse events were noted in patients receiving RT. In contrast, anorexia, diarrhea, neutropenia, and anemia were observed in 33.3%, 10%, 33.3%, and 10%, respectively, of the patients receiving CRT. The anal preserving rate, 5-year local control rate, 5-year disease-free survival rate, and 5-year survival rate were 66.7%, 73%, 77.5%, and 88.4%, respectively. RT and CRT for anal canal epidermoid cancer should be first-line treatments because of their safety and efficacy. (author)

Estos apéndices pueden sufrir torsión causando un cuadro conocido como escroto agudo. El presente trabajo tuvo como objetivo determinar las variaciones [...] de los apéndices testicular y epididimario, registrando su forma y tamaño. Se utilizaron 30 cadáveres de indivíduos adultos, Brasileños, con edades comprendidas entre 18 y 70 años, fijados en formaldehído 40%, facilitados por el Laboratorio de Anatomía Descriptiva y Topográfica de la Universidad Federal de Alagoas (UFAL), Maceió, Brasil. A través de disección se identificó la presencia de los respectivos apéndices, los que fueron medidos con un caliper manual (MetricaR), registrando su longitud y anchura. Los apéndices testiculares fueron observados en 41 testículos (68,3%) y los apéndices epididimarios en 15 casos (25%). El promedio de la longitud fue de 4,9 mm (DE=1,7) para el apéndice testicular y de 5,2 mm (DE=2,4) para el epididimario. Con respecto a la anchura de los apéndices, el promedio registrado fue de 3,2 mm (DE=1,7) para el testicular y de 2,6 mm (DE=0,9) para el epididimario.

Se presenta un paciente de 66 años que ingresa por dolor lumbar hace un año, que empeora a pesar del tratamiento médico para una presunta sacrolumbalgia. En el abdomen se aprecia marcado aumento de volumen, sobre todo hacia el hemiabdomen superior y se palpa gran masa tumoral que ocupa la totalidad del hemiabdomen superior, renitente y no dolorosa. Se realizó tomografía axial computarizada de abdomen, apreciándose imagen hipodensa multitabicada que ocupa todo el hemiabdomen izquierdo con desplazamiento de asas, riñón izquierdo y músculo psoas. Se concluye como quiste gigante multitabicado de riñón izquierdo. Se realizó laparotomía paramediana izquierda supra e infraumbilical y se detecta gran quiste renal del polo superior del riñón izquierdo que sobrepasa la línea media desplazando la arteria aorta a la derecha de la columna vertebral. Se realizó nefrectomía izquierda. Es raro, que un quiste renal simple gigante, sobrepase la línea media y tenga compresión de tantos órganos intraabdominales; este es un hecho poco descrito en la literatura médica. El examen físico superficial y limitado al órgano que produce los síntomas que motivan la consulta, limita el diagnóstico precoz de muchas enfermedades como se demuestra en este paciente. Este es uno de los errores más frecuentes que se aprecian al aplicar el método clínico. Abstract in english Frequently, cysts develop in the kidney. Among the diversity of renal cysts, the simple one could be located inside the kidney or in its surface and may be single or multiple, unilateral or bilateral, and more frequent in the left kidney. Generally they are asymptomatic and can reach a great size, c [...] alled giant cysts. We present a patient aged 66 years, entering the hospital with lumbar pain of one year that gets worse despite the medical treatment for a presumed sacrolumbal pain. It was found a remarked increase of the abdomen volume, mainly in the direction of the upper hemiabdomen and it feels a big tumoral mass filling the totality of the upper abdomen, renitent and no painful. An abdominal computer tomography was carried out, finding a multi partitioned hypodense image filling all the left hemiabdomen with displacement of loops, left kidney and psoas muscle. We arrived to the conclusion that it was a giant multi partitioned cyst of the left kidney. A left paramedian supra and infra umbilical laparotomy was carried out finding a renal cyst of the upper pole of the left kidney surpassing media line and displacing aortal artery to the right of the spinal column. A left nephrectomy was carried out. It is rare a simple renal giant cyst surpassing the media line and compressing so many intra abdominal organs; this is a fact scarcely described in the medical literature. The surface physical examination restricted to the organ producing the symptoms that motivate the consultation, interferes the precocious diagnosis of many diseases as it is shown in this patient. This is one of the most frequent mistakes committed when applying the clinical method.

    Contrast-enhanced ultrasound (US) imaging is potentially applicable to the investigation of vascular disorders of the testis. We investigated the ability of two automated computer algorithms to analyse contrast-enhanced pulse inversion US data in a rabbit model of unilateral testicular ischaemia and to correctly determine relative testicular perfusion: nonlinear curve fitting of the US backscatter intensity as a function of time; and spectral analysis of the intensity time trace. We compared (i) five metrics based on the algorithmic data to testicular perfusion ratios obtained with radiolabelled microspheres, a reference standard; (ii) qualitative assessment of the US images by two independent readers blinded to the side of the experimental and control testes to the radiolabelled microsphere perfusion ratios; and (iii) results of the algorithmically-derived metrics to the qualitative assessments of the two readers. For the curve fit method, the algorithmically-derived metrics agreed with the reference standard in 54% to 68% of all cases. For the spectral method, the results agreed in 70% of all cases. The two readers agreed with the reference standard in 40% and 35% of all cases, respectively. These results suggest that automated methods of analysis may provide useful information in the assessment of testicular perfusion.

    Full Text Available ABSTRACT Estrogens play important roles in the regulation of testis development and spermatogenesis. Moreover, several evidences suggest that estrogen signaling can be involved in testicular tumorigenesis. The physiological effects of estrogen are mediated by the classical nuclear estrogen receptors (ERs ESR1 and ESR2, which regulate both genomic and rapid signaling events.. In the last years, a member of the 7-transmembrane G protein-coupled receptor family, GPR30 (GPER, has been identified to promote estrogen action in target cells including testicular cells. Ours and other studies reported that GPER is expressed in normal germ cells (spermatogonia, spermatocytes, spermatids, somatic cells (Sertoli and Leydig cells and it is also involved in mediating the estrogen action during spermatogenesis and testis development. In addition, GPER seems to be involved in modulating estrogen-dependent testicular cancer cell growth. However, in this context, the effects of GPER stimulation on cell survival and proliferation appear to be cell type specific. This review summarizes the current knowledge concerning the functions regulated by estrogens and mediated by GPER in normal and tumor testicular cells.

El propósito de esta presentación reportar un caso clínico para ampliar conocimientos sobre el diagnóstico y tratamiento de este tipo de lesión debido a su infrecuencia en cavidad oral. La ubicación inusual de estos quistes en cavidad oral hace que, aún con una buena valoración clínica e imaginológica, el diagnóstico prequirúrgico preciso sea difícil. Es por esto que el tratamiento quirúrgico no sólo evita el riesgo de una complicación infecciosa y eventual malignización sino que permite obtener un diagnóstico definitivo mediante estudios histopatológicos. Abstract in english Dermoid cysts are benign lesions of embryonic origin, with an incidence of 0.01 % of all cysts in the oral cavity. There is no prediction by sex and about 60 % of cases develop at the age of 15 to 35 years old. Knowledge of the clinical findings of such injuries is vital for a definitive diagnosis; [...] however, this should always be confirmed by histopathological examination, especially when making a differential diagnosis between different types of dermoid cyst or other pathologies with similar clinical manifestations. The purpose of this article is to expand knowledge about the diagnosis and treatment of this type of injury because of it is not frequent in the oral cavity. The unusual location of these cysts in the oral cavity makes hard the precise preoperative diagnosis, even with good clinical and radio-graphical assessment. The surgical treatment not only prevents the risk of infectious complications and possible malignancy but also, allows obtaining a definitive diagnosis by a histopathological study.

Pese a las controversias que detallamos, nuestra opción terapéutica fue la extirpación de la masa residual tras la quimioterapia asociada a orquiectomía bilateral en el mismo acto. Concluimos que ante un tumor retroperitoneal, la existencia de alteraciones ecográficas en los testículos, pese a una palpación normal, debe hacer pensar en un "Síndrome de burn out", siendo obligatoria la biopsia testicular bilateral. La exploración quirúrgica de los mismos e incluso la orquiectomía son opciones a valorar en función de cada paciente. Abstract in english Differentiating a primary retroperitoneal seminoma from a metastatic testicular tumor with an occult testicular primary or a burned out testicular cancer remains difficult.

The patient had a retroperitoneal seminoma with ultrasonically and pathologically demo [...] nstrated abnormalities in both testes, but without evidence of tumor. The patient received chemotherapy and underwent surgery of the residual retroperitoneal mass and bilateral orchiectomy. All surgical specimens were negative for testis cancer. Conclusion: Primary extragonadal germ cell tumors in the retroperitoneum are a rare entity. The presence of a retroperitoneal tumor with ultrasonographical abnormalities in testicular evaluation should be considered as a metastases of a burned out testicular cancer, and biopsy is mandatory. Surgical evaluation and orchiectomy should be evaluated in a individual setting.

    Full Text Available A new indication for testicular tissue cryopreservation is discussed here. We evaluate the feasibility of testicular sperm extraction during bilateral orchiectomy for testicular cancer. A 26-year-old man with a history of right orchidopexy presented with primary infertility. Tests revealed left varicocele and oligospermia. He underwent varicocelectomy but was lost to follow-up. Nine months later, he presented with right-sided solid testicular swelling. Ultrasound examination confirmed the finding of possible neoplasm and revealed contralateral intratesticular lesion. Since the patient turned azoospermic, no semen sample could be cryopreserved. Permanent histopathological sections revealed bilateral classical seminomas. On processing the fresh healthy looking specimen, normal-looking viable sperm were obtained. Future attempts at in-vitro fertilization with intracytoplasmic sperm injection should be possible. This method has been described in metachronous testicular cancer, but to our knowledge, we are the first to use it in synchronous bilateral testicular tumors.

  20. Testicular cancer trends as 'whistle blowers' of testicular developmental problems in populations

    DEFF Research Database (Denmark)

    Skakkebaek, N E; Rajpert-De Meyts, E

    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/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.

En un período de 5 meses el enfermo presenta evolución tórpida con toma del estado general y elefantiasis del miembro superior izquierdo hasta región supraclavicular que obliga a realizarle amputación interescapulotorácica por la técnica de Berger para mejorar la calidad de vida. El diagnóstico histopatológico de los paquetes ganglionares resecados mostró metástasis de un carcinoma epidermoide. Abstract in english The case of a 74-year-old white male patient with a hyperpigmented and verrucose dermatological injury of more than 25 years of evolution in his left elbow and forearm is reported. He also has another cauliflower-like skin injury of recent evolution. Both presented histopathological diagnosis of chr [...] omomycosis. The initial treatment was exeresis with oncological margin of the cauliflower-like injury and electrofulguration, curettage of the rest of the injury and antimycotic treatment. In 5 months, the patient had a torpid evolution with taking of the general state and elephantiasis of the upper left extremity to the supraclavicular region that led to the interscapulothoracic amputation by Berger’s technique to improve his quality of life. The histopathological diagnosis of the resected ganglionar packages showed metastasis of an epidermoid carcinoma.

    Fertility among human beings appear to be on the decline in many Western countries, and part of the explanation may be decreasing male fecundity. A hypothesis has been put forward that decreasing semen quality may be associated with a testicular dysgenesis syndrome (TDS), a spectrum of disorders originating in early foetal life. TDS comprises various aspects of impaired gonadal development and function, including testicular cancer. A growing body of evidence, including animal models and research in human beings, points to lifestyle factors and endocrine disrupters as risk factors for TDS. We present our view of the emerging role of Leydig cell dysfunction with subsequent decreased testosterone levels in the pathogenesis of TDS Udgivelsesdato: 2008/2

  7. Echogenic mass as a sign of testicular torsion

    International Nuclear Information System (INIS)

    In most cases of testicular torsion the patient presents an anatomic predisposition due to a congenital abnormality of the tunica vaginalis, the so-called bell and clapper malformation. We present six cases of testicular torsion in which ultrasound disclosed the presence of a grossly lobular, extra testicular, echogenic mass. At surgery, it was found to coincide with the morphological changes exhibited by torsion of mediastinum testis and spermatic cord. Th knowledge of the nature of this image prevents its erroneous interpretation and its being confused with other structures such as enlarged epididymis testicular appendages, scrotal hernia, etc. (Author) 17 refs

    Non-clinical safety assessment is essential during the drug development process in the pharmaceutical industry, and involves numerous, detailed in vitro and in vivo toxicology tests (general, reproductive and genetic), and safety pharmacology studies. The testis is a common organ for adverse drug effects leading to attrition of potential compounds. It would, therefore, be useful to detect testicular toxicity as early as possible in the drug development process. Histopathology is the standard ...

    Testicular germ cell tumors (TGCT) are the most common malignancy in young men. While most TGCT are potentially curable, approximately 5% of patients with TGCT may develop chemoresistance and die from the disease. This review article summarizes current knowledge in genetics underlying the development, progression and chemoresistance of TGCT. Most post-pubertal TGCT originate from intratubular germ cell neoplasia unclassified (IGCNU), which are transformed fetal gonocytes. Development of IGCNU...

    In the last decades, its incidence showed a progressive increased probably due to genetic and environmental factors. Despite exposure to some viruses such as HIV, HCV, EBV and HPV is frequently related to cancer development, there are no studies aimed to evaluate the possible implication of viral infections in the pathogenesis of testicular cancer. In this study we analyzed sperm parameters and prevalence of HPV on sperm in 155 testicular cancer patients at diagnosis (T-1, after orchiectomy (T0 and after 12 months from surgery or from the end of adjuvant treatments (T12. All patients showed a significantly higher prevalence of semen infection than controls (9.5% and 2.4% respectively and altered sperm parameters both at T-1 and T0. Considering sperm parameters, at T-1 we observed a reduction of progressive motility, and after orchiectomy patients showed a reduction of sperm concentration and count and a further worsening of motility. Thereafter, patients were assigned to three groups on the basis of medical option after surgery: S = surveillance, R = radiotherapy and C = chemotherapy +/- radiotherapy. At T12, untreated patients had an improvement of sperm parameters while R group and even more C group had a strong decrease of sperm number (p<0.01 both vs T0 and S group. Moreover, patients who received radio and/or chemotherapy had a very high prevalence of HPV semen infection (S: 7.7%, R: 30.8% and C: 61.5%. In conclusion, patients with testicular cancer had frequently altered sperm parameters and higher prevalence of HPV semen infection that were worsened after radio and chemotherapy. Because HPV infection is a risk factor for cancer development and it may further reduce fertility, we suggest screening for HPV in testicular cancer patients at diagnosis and particularly after adjuvant treatments.

    International Nuclear Information System (INIS)

    Under supervision there were 53 patients epidermoid of lung cancer by which radial therapy under the radical program (Muravskaja G. V. and co author 1998)was carried out . The purpose of work was studying results of radial treatment epidermoid lungs cancer under the radical program and some factors of the prognosis. The diagnosis of epidermoid lungs cancer patients has been confirmed by morphologic. All patients were under supervision more than 1 year.27 from the above stated patients (the first group) 26 patients (the second group)-less than one year lived more than 1 year (51.0%). The two year survival rate of patients of the first group has made 15.1% .Three year survival rate - 11.3% . Results correspond to the literary data(Bauman M.2001)distinction on age was not. At the analysis of distribution of patients on a degree of prevalence of a tumour it is established , that in the first group it was observed: T2NO-4;T2N1-4;T2-3N2,T3NO-1-19,accordingly, in the second group: T2 N0-3,T2N1-2;T2-3N2,T3N1-14;T2-3 N3-7. In both groups prevailed 111 degree of disease:in the first -70,9%,in the second 80.8%. But in group of patients living less than one year, in 26,9% was observed metastatic spreading tumours in the lymphatic nodes, corresponding to category N3. In the second group also much more often are atelectasis, not allowed radiographical to limit a shadow of a tumour from a shadow atelectasis (58.0±9.7% and 30.0±8.8%,p<0.05).Frequency full resorption tumours was obsrequency full resorption tumours was observed in the first group in 37.0±9.3%, in the second 3.9±3.8%, almost in 10 times it is less. The received data specify direct correlation between the loco-regional control and lymphogenous distribution epidermoid lungs cancer, presence of atelectasis.In the latter case deterioration of results is probably caused by impossibility at radiological research to define border a tumour and atelectasis that is important at planning volume of irradiation.I n this connection other method of visualization are necessary for restriction of a tumour from atelectasis

  17. Pauci-symptomatic large epidermoid cyst of cerebellopontine angle: case report.

    Science.gov (United States)

    Di Rienzo, L; Artuso, A; Lauriello, M; Coen Tirelli, G

    2004-04-01

    It is estimated that 10% of intra-cranial tumours are localized in the cerebellopontine angle and internal auditory canal and early symptoms of the different histological forms are almost identical. Acoustic neuroma account for 90% and meningioma for 5-10% of these tumours, while a small percentage of rare tumours exist, the most frequent being epidermoid cyst, also known as congenital cholesteatoma or keratoma. The case is reported here of a large epidermoid cyst of the right cerebellopontine angle, and the clinical-radiological course is reviewed. The patient, a 35-year-old, male, initially presented an episode of objective rotatory vertigo, and a history of right ear fullness, of a few months' duration, with normal otoscopy. Audiometric test was normal in left ear, while slight pantonal sensori-neural hypoacusia was observed in the right ear. The impedenzometric findings were normal as was the vestibular test. Auditory brainstem evoked response showed an increased latency of fifth wave. Gadolinium-enhanced magnetic resonance imaging of brain revealed the presence of a voluminous epidermoid cyst occupying the extra-axial side of the right cerebellopontine cistern with superior extension into the cistern. Due to the low-grade of symptoms, we had chosen to wait and not perform surgery immediately, with otologic and vestibular test-controls every 6 months, with cerebral magnetic resonance imaging to control extension of the mass, without radiation exposure for the patient. One year after diagnosis, at the last control, otofunctional findings were not modified and repeat magnetic resonance imaging did not demonstrate important variations compared to the first. Thus, the choice not to proceed with surgery was justified since surgery is burdened by the risk of important complications. At magnetic resonance imaging, the epidermoid cyst, unlike the majority of intra-cranial tumours, such as acoustic neuroma and meningioma, does not show gadolinium-enhancement; this again supporting the important role of magnetic resonance imaging in the differential diagnosis of intra-cranial neoformations. It is, therefore, worthwhile stressing the validity of the approach, step by step, in the diagnosis of patients with otologic symptoms, together with the importance of magnetic resonance imaging that, in comparison with computed tomography, allowed us to exactly assess the growth rate of the mass and to "wait and see" without risks and without radiations for the patient.

    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.

  19. Perinatal testicular torsion and medicolegal considerations.

    2014-06-01

    Perinatal testicular torsion (PTT) is a very complex condition because of rarity of presentation and diagnostic and therapeutic difficulties. In presence of perinatal testicular torsion, the involvement of contralateral testis can be present also in absence of other indications which suggest the bilateral involvement; therefore, occurrences supported by literature do not exclude the use of surgery to avoid the risk of omitted or delayed diagnosis. The data on possible recovery of these testicles are not satisfactory, and treatment consists of an observational approach ("wait-and-see") or an interventional approach. The hypothesis of randomized clinical trials seems impracticable because of rarity of disease. The authors present a case of PTT, analyzing injuries due to clinical and surgical management of these patients, according to medicolegal profile. The delayed diagnosis and the choice of an incorrect therapeutic approach can compromise the position of healthcare professionals, defective in terms of skill, prudence and diligence. Endocrine insufficiency is an unfortunate event. The analysis of literature seems to support, because of high risk, a surgical approach aimed not only at resolution of unilateral pathology or prevention of a relapse, but also at prevention of contralateral testicular torsion.

    Full Text Available OBJECTIVE: The aim of this prospective study was to compare the resistive index (RI) values, which is a parameter of testicular parenchymal perfusion, in testicular microlithiasis (TM) cases and normal cases. MATERIALS AND METHODS: 2179 volunteers, all healthy men (17-42 years of age) from the Annua [...] l Army Reserve Officer Training Corps training camp were included in the study. A screening scrotal ultrasound was performed and all men diagnosed with TM underwent a scrotal Doppler ultrasonography scan (US). US examinations were performed for subjects with TM and without TM as a control group and RI was determined. RESULTS: 53 men with TM were identified in the 2179 US. Spectral Doppler examination was applied to 50 randomly selected cases (100 testicles) without TM and 92 testicles with TM, 39 cases (78 testicles) with bilateral and 14 cases with unilateral involvement. However, 48 normal testicles (17 bilateral and 14 unilateral) and 47 testicles with TM (15 bilateral and 17 unilateral, 10 of which were cases with bilateral TM) where flow from the centripetal artery could be obtained and analyzed were included in the statistical analysis for resistive indices. There was no significant difference regarding the RI and spectral examinations between subjects with and without TM. An interesting finding was the twinkling artifact observed in three cases. CONCLUSION: Microliths did not alter the RI values and thus had no influence on testicular perfusion on Doppler US examination.

    Congenital dilatation of the bile duct and its incidence is a rare condition reported in one in 100 000 to 150 000 newborns. Current concern about the evolution of this process is that a cholangiocarcinoma might appear. The case of a female teenager of urban origin, who attended her health area polyclinic, because of a moderate 5 months pain in her high epigastrium and in her upper right abdomen is presented. The pain appeared always after eating accompanied by vomiting and it was self-relieved. An abdominal ultrasound indicated by the patient’s family doctor showed a liver cyst. It was decided to perform an abdominal computed tomography. Through this test a cyst at the pancreatic head was found. The patient was admitted in the emergency room of the ‘’Gustavo Aldereguía Lima’’ Hospital of Cienfuegos, where she was evaluated by the physicians in the Surgery Department. It was decided to treat her surgically. Anatomopathologic results showed chronic cholecystitis, choledochal cyst and nonspecific chronic inflammation.

Although rare, intracranial EC have been mainly described in the posterior fossa, with the supratentorial location considered exceptional. Apart from the low frequency of these le [...] sions, their pathoembriology still remais unknown. We report a patient with a huge frontal EC and review the literature. A 62-year-old man presented with abnormal behaviour, disorientation and decreased level of consciousness after moderate head injury. Initial cranial CT scan revealed a large cyst in the left frontal region with marked midline shift. Emergency puncture and decompression of the cyst demonstrated a milky fluid with high protein levels. Cranial MRI after patient improvement confirmed the existence of the cystic lesion with less mass effect. Delayed surgery was performed with craniotomy and total removal of the cyst. Pathological examination confirmed the presence of a typical EC. Patient made a complete recovery on follow-up with no recurrence on postoperative MRIs. Differential diagnosis of EC based on radiological data is quite difficult. As aggresive behaviour of this condition has been described following incomplete resections, the treatment of choice is a radical removal of the cyst in one or two stages depending on patient clinical condition.

The fertility percentage obtained in hydatid cysts from ovine with "in vitro" viables protoescoleces was 43.97% being 43.02% in pulmonary cysts and 46.16% in hepatic cysts. The viability of protoscoleces was demonstrated by production of a secondary hydatid disease in 100% of gerbils infested. CONCLUSIONS: It is emphasized the validity of the criteria used to study the viability "in vitro" of the protoescoleces from hydatid cysts of origin ovine. The secondary hydatid produced in gerbils leads us to consider them as experimental animal for investigation "in vivo" of hydatid disease of origin ovine.

  8. Squamous cell carcinoma arising in the wall of epidermoid cyst of axilla: a case report

    International Nuclear Information System (INIS)

    Epidormoid cysts are benign epithelial cysts often occurring within the skin of face and trunk. But carcinomatous change is rare. The authors experienced a case of squamous cell carcinoma arising from the wall of epidermoid cyst of axilla and report the radiologic and pathologic findings with a brief review of the literatures. Plain chest radiograph, US and enhanced CT of axilla were taken. We analyzed radiologic findings of squamous cell carcinoma in the wall of epidermoid cyst of axilla and correlated with pathologic findings. Plain chest radiograph revealed a huge axillary mass without bony destruction or calcification. US showed a heterogenous hyperechoic mass with eccentrical cystic lesion. Outer margin of the mass was irregular. No posterior acoustic enhancement was seen. Postcontrast CT scan showed a circumscribed complex mass with irregular enhancing rim. During operation mass was located within subcutaneous layer and internal contents of the mass were brown, necrotic keratinous debris. Differentiation from solid tumor was difficult. But intradermal or subcutaneous location and rapid growing were characteristic

  9. FGF2 mediates DNA repair in epidermoid carcinoma cells exposed to ionizing radiation

    International Nuclear Information System (INIS)

    Fibroblast growth factor 2 (FGF2) is a well-known survival factor. However, its role in DNA repair is poorly documented. The present study was designed to investigate in epidermoid carcinoma cells the potential role of FGF2 in DNA repair. The side population (SP) with cancer stem cell-like properties and the main population (MP) were isolated from human A431 squamous carcinoma cells. Radiation-induced DNA damage and repair were assessed using the alkaline comet assay. FGF2 expression was quantified by enzyme linked immunosorbent assay (ELISA). SP cells exhibited rapid repair of radiation induced DNA damage and a high constitutive level of nuclear FGF2. Blocking FGF2 signaling abrogated the rapid DNA repair. In contrast, in MP cells, a slower repair of damage was associated with low basal expression of FGF2. Moreover, the addition of exogenous FGF2 accelerated DNA repair in MP cells. When irradiated, SP cells secreted FGF2, whereas MP cells did not. FGF2 was found to mediate DNA repair in epidermoid carcinoma cells. We postulate that carcinoma stem cells would be intrinsically primed to rapidly repair DNA damage by a high constitutive level of nuclear FGF2. In contrast, the main population with a low FGF2 content exhibits a lower repair rate which can be increased by exogenous FGF2. (authors)

Resultados: De 142 casos de pacientes operados por quiste del conducto tirogloso, se registraron 9 casos de cáncer papilar (6,34%). El promedio de edad de los pacientes fue de 32 años. El diámetro promedio de la lesión fue de 4,4 cm (DS 2,2 cm). Del total, 8 pacientes fueron sometidos a tiroidectomía total, se diagnosticó cáncer de tiroides en 3 de ellos, en 6 se asoció tratamiento con radioyodo. En sólo 1 paciente se realizó una disección linfonodal. El tiempo promedio de seguimiento fue de 85 meses; a la fecha la serie no ha presentado recurrencia ni mortalidad. Conclusiones: Si bien el manejo más seguro a largo plazo es la cirugía de Sistrunk, asociado a una tiroidectomía y eventual radioyodo, la resolución quirúrgica con tiroidectomía asociada debe ser considerada cuando la morbilidad no sea mayor que el beneficio teórico. Abstract in english Introduction: In about 1-2% of cases of thyroglossal cyst may be neoplastic changes, mostly correspond to papillary thyroid carcinoma (75-85%).

Materials and Methods: Data were recorded retrospectiv [...] ely from patients diagnosed with papillary thyroid carcinoma in thyroglossal duct cyst treated at Hospital Clinico Universidad de Chile between 1999-2014. Results: From 142 cases operated for thyroglossal duct cyst, 9 cases of papillary cancer (6.34%) were recorded. The average age was 32 years. The average diameter of the lesion was 4.4 cm (SD 2.2 cm). 8 patients underwent total thyroidectomy; a simultaneous thyroid cancer was diagnosed in 3 of them. In 6 cases was added iodine therapy. In only one patient a lymph nodal dissection was performed. We do not observe any surgical complication. A solid component in preoperative ultrasonographic study is suspicious of malignancy. The average follow-up time was 85 months. There is no recurrence or mortality in this group of patients. Conclusions: Although the safest long-term management is Sistrunk surgery associated with thyroidectomy and radioiodine in selected cases, these patients must be evaluated by a multidisciplinary group and thyroidectomy should be considered in high surgical volume center, in order to minimize complications.

  2. Ultrasonographic Findings of Prepubertal Testicular Teratoma

    International Nuclear Information System (INIS)

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

  3. Radiotherapy Treatment Planning for Testicular Seminoma

    International Nuclear Information System (INIS)

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

    2006-01-01

    Full Text Available Testicular neoplasia constitutes a chapter of particular interest in oncology, given its increased curability in comparison with most solid tumors. Early diagnosis is important because it allows the patients to be treated in the first stages of the disease, in which morbidity associated with therapy is minimal, and increased survival represents certitude. The medical staff, as well as the general population, must be advised upon suggestive signs and symptoms, and also on the imaging characteristics of such cancers (ultrasound and CAT scans being in the spotlight, so that the period of time until confirmation of the diagnosis (by pathology exam – which in turn influences therapy decision – is obtained may be as short as possible. Surgery represents a very important component of multimodal therapeutic strategy for patients diagnosed with testicular cancer, both for low/volume tumors and for the more advanced stages of disease. Surgical interventions (orchiectomy, retroperitoneal lymph node resection with or without sympathic nerve preservation, resection of singular metastases contribute decisively to the high percentage of long term cures, and can play a role in increasing the survival of patients with chemoresistant metastatic disease. Chemotherapy is mandatory in the treatment of locally advanced and metastasis seminomatous germ cell tumors (GCT. This may be seen also as an option to annihilate possible pathology diagnostic errors (mostly due to lack of tumour marker dosing which determine a non-seminomatous GCT to be treated as a seminoma, thus greatly diminishing therapeutic efficacy. There are several chemotherapeutic agents with extremely efficient activity on seminomatous testicular tumours, but the etoposide/cisplatin protocol remains still the gold standard. Non-seminomatous GCTs have a lesser response to chemotherapy and therefore a higher relapse rate and a poorer prognosis.

    We report the case of an 83 years old man supported for painless indurated and nodular lesion of the left testicle. Histological analysis identified a primary cutaneous melanoma metastasis although it has never been found on physical examination. The discovery of a testicular mass should suggest first a germ cell tumor, despite in some populations (age over 60 years), other diagnosis are more frequent, including metastasis. Due to rapid disease progression and high mortality rate within a short interval, a complete staging looking for other secondary locations must be done and a multidisciplinary care and palliative involvement must also be initiated in the context of metastatic melanoma.

    Serum testosterone levels are increased in athletes after short-term exercise. To investigate whether mechanical compression could contribute to this increase, we subjected 14 male volunteers to mechanical testicular compression via a pneumatic cuff. The serum testosterone levels were sampled at time intervals before, during and after compression. There was a rise in mean serum testosterone levels of 16.7-18.2%, with a maximal increase at 1.5 min after compression was released. Mechanical compression alone did not explain the rise in serum testosterone, although it may have a contributory role. PMID:8498875

  12. Prognostic role of p53 protein expression in epidermoid carcinoma of the anal canal

    International Nuclear Information System (INIS)

    Purpose: To assess the prognostic significance of p53 protein expression in patients with primary epidermoid carcinoma of the anal canal managed by radiation therapy (XRT), 5-fluorouracil (5-FU), and mitomycin C (MMC). Methods and Materials: From January 1991 to December 1993, 58 consecutive patients with primary epidermoid carcinoma of the anal canal were treated in a prospectively designed protocol of XRT (24 Gy/12--3((1)/(2)) wk split--28 Gy/14) and concurrent 5-FU (1000 mg/m2/day 1-4) and MMC (10 mg/m2 day 1) of each cycle of XRT. Paraffin-embedded tumor samples were unavailable in 9 patients, leaving 49 patients in the study. Expression of p53 protein was studied using immunohistochemistry and quantified as percent tumor nuclei showing positive staining. Actuarial survival and disease-free survival (DFS) rates were estimated by the Kaplan-Meier method, and compared using the log-rank test. A Cox proportional hazard model was used for the multivariable analysis. Results: There were 6 T1, 26 T2, 7 T3, and 10 T4 lesions. Primary tumor sizes ranged from 1-15 cm with a median of 4 cm. There were 6 patients with nodal metastases. Median follow-up was 4.5 years. Positive nuclear immunostaining for p53 was observed in 40 of 49 patients. The median percent positive staining was 5%, with 13, 9, and 18 patients showing staining in <5%, 5 to <10%, and 10-50% of tumor nuclei respectively. There was no correlation of percent p53 staining with gender, age, of percent p53 staining with gender, age, tumor stage, size, or histology. Local, regional, and distant failures were observed in 12, 2, and 2 patients respectively. The 5-yr survival and DFS were 84% and 64% respectively. In univariate analysis, the only prognostic variable for survival was gender. For DFS, advanced T category and large tumor size were predictive of poor DFS. In multivariate analysis, poor DFS was associated with high T category (p = 0.0008), basaloid histology (p = 0.001), male gender (p = 0.002), and increasing percent of p53 protein expression (p 0.01). Conclusions: It is concluded that expression for p53 protein is present in a high percentage of patients with epidermoid carcinoma of the anal canal. For patients managed with combined XRT, 5-FU, and MMC, percent p53 protein expression is of prognostic value for DFS independent of other clinical factors such as T category, gender, and histology

    Most testicular germ cell tumors originate from carcinoma in situ cells in fetal life, possibly related to sex hormone imbalances in early pregnancy. Previous studies of association between gestational age at birth and testicular cancer have yielded discrepant results and have not examined extreme preterm birth. Our objective was to determine whether low gestational age at birth is independently associated with testicular cancer in later life. We conducted a national cohort study of 354,860 men born in Sweden in 1973–1979, including 19,214 born preterm (gestational age <37 weeks) of whom 1,279 were born extremely preterm (22–29 weeks), followed for testicular cancer incidence through 2008. A total of 767 testicular cancers (296 seminomas and 471 nonseminomatous germ cell tumors) were identified in 11.2 million person-years of follow-up. Extreme preterm birth was associated with an increased risk of testicular cancer (hazard ratio 3.95; 95% CI, 1.67–9.34) after adjusting for other perinatal factors, family history of testicular cancer, and cryptorchidism. Only five cases (three seminomas and two nonseminomas) occurred among men born extremely preterm, limiting the precision of risk estimates. No association was found between later preterm birth, post-term birth, or low or high fetal growth and testicular cancer. These findings suggest that extreme but not later preterm birth may be independently associated with testicular cancer in later life. They are based on a small number of cases and will need confirmation in other large cohorts. Elucidation of the key prenatal etiologic factors may potentially lead to preventive interventions in early life. PMID:22314417

  18. Proliferating cell nuclear antigen PCNA expression in lung epidermoid carcinoma LL tissues after photosensitized tumour therapy

    International Nuclear Information System (INIS)

    Cell proliferation associated markers are known to serve as an important attributes of tumour biologic characteristic and its response to treatment. The study was undertaken to perform immunohistochemical analysis of expression of one of the main cell proliferation associated markers -proliferating cell nuclear antigen PCNA, in histological specimens of experimental tumours obtained after photosensitized tumour therapy (PTT) or combination of PTT with adriamycin and to evaluate tumour stress response to treatment. Immunomorphological investigation of lung epidermoid carcinoma LL revealed heterogeneity in morphological patterns of treatment-induced cell death. Data obtained show that PCNA expression in tumour cell induced by treatment with PTT or PTT combination with adriuamycin could be linked to cell proliferation and repair processes as well as to triggering of cell death execution.

    In order to investigate whether unilateral testicular torsion exerts a negative influence on the previously undisturbed contralateral side, exocrine and endocrine testicular function were evaluated before and two months after torsion. A rat model with 6 hours', 12 hours' or permanent extravaginal 540 degrees torsion of the right testis was used; a sham operated group of animals served as controls. Ejaculates were collected by electrostimulation; LH, FSH and testosterone serum levels were determined by radioimmunoassays. Eight weeks after torsion sperm output had decreased by half in the experimental groups, and LH levels increased significantly, whereas the other hormone levels, as well as the controls, remained unchanged. Morphometry of the contralateral testis revealed no alterations except a significant increase of the Leydig cells and interstitial cells in some subgroups. All observed changes correlate with the functional loss of one testis; definite evidence for contralateral damage was not observed. PMID:3125648

    In general, sperm production decreases with advanced age in men. Therefore the present work compares the histology and cellularity of aging human testis with that of a young adult. Gonads from three patients 69 years old and testis from a young subject (aged 25 years) were examined after histological standard techniques (PAS-Haematoxyline). Histological, morphometric and cell counting analyses of testicular sections revealed that the seminiferous tubules of senile patients were of smaller dia...

    Full Text Available OBJETIVOS: Tumores testiculares são uma rara condição associada à hiperplasia adrenal congênita (HAC que decorrem da hiperplasia de restos adrenais intratesticulares (HRA, raramente ocorrendo associados a neoplasias malignas. Sua diferenciação histológica com tumores de células de Leydig é muito difícil, podendo levar a orquiectomias desnecessárias. O objetivo deste relato foi apresentar esse dilema diagnóstico em um paciente com HAC e tumores testiculares bilaterais. MÉTODOS: Relatou-se o caso de um paciente masculino, 16 anos, com diagnóstico de HAC desde os 3 anos de idade, que apresentava tumorações testiculares endurecidas, indolores e de crescimento lento, sendo encaminhado para orquiectomia bilateral. RESULTADOS: Foi decidido por tratamento conservador com prednisona, havendo significativa diminuição do volume testicular e normalização dos níveis de andrógenos. CONCLUSÃO: Este caso demonstra a importância de sempre se considerar a hipótese de HRA intratesticulares no diagnóstico diferencial dos tumores testiculares. A investigação e a conduta devem ser conduzidas de maneira cautelosa para se evitar orquiectomias desnecessárias.OBJECTIVES: Testicular tumors are a rare condition associated with congenital adrenal hyperplasia (CAH, originated from intratesticular adrenal rest tumors, and they are rarely associated with malignant tumors. Their histological differentiation from Leydig-cell tumors is quite difficult, which would lead to inappropriate orchiectomies. Thus the objective of this report was to present this diagnostic dilemma. METHODS: Reported the case of 16-yr-old boy with previous diagnosis of CAH with bilateral testicular enlargement who was recommended to be submitted to a bilateral orchiectomy. RESULTS: Considering this findings, it was decided to treat conventionally with prednisone with significant reduction of testicular volume, and normalization of androgens levels. CONCLUSION: This case shows the importance of intratesticular adrenal rest tumors in the differential diagnosis of testicular tumors. Cautious approach during investigation and treatment are recommended to avoid inappropriate orchiectomies.

Abstract in english Objective: We report the case of a 11 year- old girl with thyroglossal cyst and cholesterol granuloma, an unusual finding that clinically simulates thyroid carcinoma. This association is unusual and there are few reported cases worldwide. Case report: An 11-year-old girl consulted for dysphagia and [...] a 3 x 3 cm hard mass. The mass was painful on palpation and was located in the anterolateral neck left. It was phlogosis-free. A neck ultrasound showed a 1.8 x 0.9 cm permeable midline thyroglossal conduct with a hypoechoic nodule with well-defined edges but without calcifications. A 3 x 2,5 x 0, 8cm tumor was removed. A 0.8 cm cystic cavity that contained gelatinous material was observed. Below that cavity, a well-circumscribed nodule was observed. It measured 1.5 cm and was made up of firm yellowish tissue. The histopathology examination revealed a cyst lined with columnar epithelium and inflammatory linfohistiocitic response with foreign body type giant cells around cracks that corresponded to a cholesterol deposit. Conclusion: We present this case because it is very unusual and because it can be clinically and radiologically mistaken for a malignant tumor. It could be the first case ever reported in Venezuela.

RELATO DE CASO: Descrevemos um caso de carcinoma espinocelular (CEC) de pulmão com metástase em cólon e tireoide, em mulher de 66 anos. A lesão era irressecável, e foi iniciada quimioterapia. A paciente evoluiu com suboclusão intestinal e a colonoscopia evidenciou pólipo colônico cuja biópsia e imunoistoquímica (IHQ) foram compatíveis com CEC de origem pulmonar. Em consulta de acompanhamento, detectou-se nódulo tireoidiano cuja punção aspirativa e IHQ de cellblock confirmaram CEC de origem pulmonar. Após quimioterapia de terceira linha, a paciente evoluiu com abdome agudo obstrutivo por massa retroperitoneal, sendo submetida a laparotomia exploradora, vindo a falecer por complicações da cirurgia. Metástases para tireoide e cólon são raramente reportadas em carcinomas epidermoides de pulmão. O envolvimento gastrointestinal por metástases de pulmão pode acometer estômago, intestino delgado e cólon, e casos de sangramento e perfuração já foram reportados.

Abstract in english CONTEXT: Non-small cell lung cancer (NSCLC) progresses to distant metastases in most cases.

Dissemination to the skin, myocardium, thyroid gland and intestine may occur, but is rare. CASE [...] REPORT: We describe a case of squamous cell carcinoma in the lungs, with metastases in the colon and thyroid, in a 66-year-old female patient. The lesion was unresectable and chemotherapy was started. The patient evolved with intestinal subocclusion, and colonoscopy showed the presence of a polyp. Biopsy and immunohistochemical analysis on the polyp showed that it was compatible with squamous cell carcinoma of pulmonary origin. At a follow-up consultation, the patient presented a thyroid nodule. A aspiration biopsy and cellblock immunohistochemistry confirmed the squamous cell carcinoma of pulmonary origin. After third-line chemotherapy, the patient progressed with acute obstructive abdomen due to a retroperitoneal mass. She underwent exploratory laparotomy and died due to surgical complications. Metastases to the thyroid and colon are rarely reported in cases of epidermoid carcinoma of the lungs. Gastrointestinal involvement in pulmonary metastases may affect the stomach, small intestine and colon, and cases of bleeding and perforation have already been reported. Although richly vascularized, the thyroid is an infrequent site for metastases. Such sites reflect poor prognoses for the clinical evolution. We did not find any previous reports in the literature, on lung cancer with metastases concomitantly in the colon and thyroid, in a single patient.

  17. Reversible harmless interruption of testicular blood supply in the ram

    International Nuclear Information System (INIS)

    An effective method of interrupting testicular blood flow temporarily and repeatedly in the ram has been developed. Blockade of flow has been achieved mechanically by an inflatable occluder placed around the testicular artery at the level of the spermatic cord. The effect of the blockade on total testicular blood supply was investigated using Doppler flowmetry and a percutaneous Xenon-133 injection method. With both approaches, the blood flow changes after inflation or deflation of the occluders could be estimated satisfactorily. A substantial decrease of testicular blood flow was achieved in eight of the 10 testes with inflated occluders. However, there were indications that in the remaining two testes blockade of the arterial flow was not complete. After deflation of the occluders, blood flow was restored rapidly and completely in all testes. Macro- and microscopic examinations revealed no long-term damage to the testis after blood flow interruptions lasting 30 or 60 minutes

    Full Text Available Crossed testicular ectopia (CTE/transverse testicular ectopia (TTE is a rare but well known congenital anomaly, in which both gonads migrate toward the same hemiscrotum. It is usually associated with other abnormalities such as persistent Mullerian duct syndrome, true hermaphroditism, inguinal hernia, hypospadias, pseudohermaphroditism, and scrotal anomalies. About 100 cases of transverse testicular ectopia have been reported in published studies. We report a case of transverse testicular ectopia in an 8-month-old boy who presented with right inguinal hernia and nonpalpable left testis. On exploration, both testes were present in the right inguinal region. Bilateral orchiopexy was performed by crossing the left testis in the extra-peritoneal space and ipsilateral scrotal orchiopexy. The diagnosis could not be made preoperatively in most of reported cases.

    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.

  1. Non-seminomatous testicular germ cell tumours

    International Nuclear Information System (INIS)

    This report deals with the preliminary results of trials in the DATECA project with stage I, II and III patients with non-seminomatous germ cell tumours. Stage 1 patients were randomized between infradiaphragmatic irradiation and observation. No significant difference in recurrence rates has been observed as yet. Eighteen of 95 patients had recurrence with a median time to relapse of 3 months. Fifteen patients achieved complete remission after treatment by combiantion chemotherapy while 3 patients are still undergoing treatment. Stage II patients received 6 series of cis-platinum, bleomycin, and vinblastine. The patients were initially randomized to receive chemotherapy alone versus chemotherapy plus irradiation. Irradiation led to increased toxicity and decreased doses of the antineoplastic drugs. Fifty-one patients were studied. The overall complete remission rate was 89 per cent including 7 patients who achieved complete remission after secondary surgery. Three patients died from testicular tumours and two toxic deaths occurred in this group. Stage III patients were treated with 6 series of cis-platinum, bleomycin, and vinblastine. Fifty patients were studied. The complete remission rate was 72 per cent including 2 patients who achieved complete remission after secondary surgery. Sixteen patients relapsed after achieving complete remission with a median time to relapse of 4 months. Eight of these died, 4 achieved a new complete remission, while 4 patients are stilllete remission, while 4 patients are still under treatment. Sixty per cent of the patients are at present alive without evidence of disease, while 12 patients died from testicular tumours and 2 from toxic side effects. (orig.)

    Most amphibians present an annual testicular cycle characterized by a quiescent period (late autumn-winter) and a spermatogenic period (spring and summer). At the end of the period of spermatogenesis undifferentiated interstitial cells transform into steroid-secreting Leydig cells which regress in spring at the beginning of the new spermatogenetic cycle. The testicular cycle is controlled by the pituitary gonadotropin levels which are high in autumn and win...

    We describe our experience with BEP (bleomycin, etoposide, cisplatin) therapy as chemotherapy for testicular tumors in 11 patients. Eight were non-seminomatous testicular cancer patients and 3 were seminoma patients. Three of 8 non-seminomatous testicular cancer patients had no evident metastasis and BEP therapy was performed for prophylaxis of recurrence. Other 5 non-seminomatous testicular cancer patients and 3 seminoma patients had metastatic lesions and BEP therapy was performed to cure these metastatic lesions. Ten of our 11 patients are living and disease-free. One non-seminomatous testicular cancer patient who had brain, lung, eye and bladder metastases and had an extremely elevated human chorionic gonadotropin (hCG) level responded only partially and died later due to disease progression. Side effects in most patients were nausea, vomiting, alopecia and leucopenia and all these side effects were reversible. Neuromuscular toxicity such as paresthesia or abdominal cramp that is sometimes encountered in PVB (cisplatin, vinblastine, bleomycin) therapy was not seen in our patients. Our results support the concept that BEP therapy is better than PVB therapy as an initial chemotherapy for testicular tumors. PMID:1282774

  1. Data required for testicular dose calculation during radiotherapy of seminoma

    International Nuclear Information System (INIS)

    The purpose of this study was to provide the required data for the direct calculation of testicular dose resulting from radiotherapy in patients with seminoma. Paraortic (PA) treatment fields and dog-leg (DL) portals including paraortic and ipsilateral pelvic nodes were simulated on a male anthropomorphic phantom equipped with an artificial testicle. Anterior and posterior irradiations were performed for five different PA and DL field dimensions. Dose measurements were carried out using a calibrated ionization chamber. The dependence of testicular dose upon the distance separating the testicle from the treatment volume and upon the tissue thickness at the entrance point of the beam was investigated. A clamshell lead shield was used to reduce testicular dose. The scattered dose to testicle was measured in nine patients using thermoluminescent dosimeters. Phantom and patient exposures were generated with a 6 MV x-ray beam. Linear and nonlinear regression analysis was employed to obtain formulas describing the relation between the radiation dose to an unshielded and/or shielded testicle with the field size and the distance from the inferior field edge. Correction factors showing the variation of testicular dose with the patient thickness along beam axis were found. Bland-Altman statistical analysis showed that testicular dose obtained by the proposed calculation method may differ from the measured dose value by less than 25%. The current study presents a method providing current study presents a method providing reasonable estimations of testicular dose for individual patients undergoing PA or DL radiotherapy

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

Entre enero de 1984 y abril de 2008, 12 pacientes (0.9%) de 1.253 casos con hematoma subdural crónico presentaban un quiste aracnoideo intracraneal. La localización de los quistes fue en 10 casos en la fosa temporal y los otros dos en la convexidad. Los síntomas de presentación fueron cefalea en 6 pacientes (50%), seguidos por convulsiones (3 casos). En once pacientes se realizó agujero de trépano y drenaje del HSC, la paciente de más edad fue tratada de forma conservadora. Únicamente se trataron 3 quistes aracnoideos mediante craneotomía y fenestración, con resolución completa del quiste. Conclusiones. Los pacientes con quiste aracnoideo, sobre todo si esta localizado en la fosa temporal, tienen un mayor riesgo de sufrir un hematoma subdural crónico. La primera opción terapéutica es el drenaje del hematoma subdural y si persiste la sintomatología deberá tratarse el quiste aracnoideo. Abstract in english Introduction. We designed this study to investigate the clinical, neurological, and radiological outcome of patients with chronic subdural hematoma related to an intracranial arachnoid cysts. Patients and methods. Medical records of 12 cases of patients with arachnoids cyst complicated with chronic [...] subdural hematoma were retrospectively reviewed. Results. Between January 1984 and April 2008, 12 patients (0.9%) of 1.253 cases of chronic subdural hematoma surgically treated in our hospital had associated arachnoid cyst. Arachnoid cysts were located in the middle fossa (10 cases) and convexity (2 cases). The most frequent symptom was headache (6 cases), followed by seizures (3 cases). Eleven patients underwent burr hole and drainage; the oldest patient was treated conservatively. Conclusions. Patients with AC, especially when these are located in temporal fossa, appear to harbour a life-long risk of contracting subdural hematoma. Hematoma evacuation is adequate at first operation and if arachnoid cyst is symptomatic or preoperative symptoms persist, additional arachnoid cyst surgery should be considered.

  5. Radiation therapy for epidermoid carcinoma of the anal canal, clinical and treatment factors associated with outcome

    International Nuclear Information System (INIS)

    Background and purpose: In recent years, treatment with combined chemotherapy and radiation has become the standard of care for epidermoid carcinoma of the anus. However, optimal radiotherapy techniques and doses are not well established. Materials and methods: During the period 1975-1997, 106 patients with epidermoid carcinoma of the anal canal underwent radiation therapy. Treatment policies evolved from radiation therapy alone or with surgery, to combined chemotherapy and radiation followed by surgery, to combined chemotherapy and radiation. Results: Overall 74% of patients were NED (no evidence of disease) at last follow-up. The most important clinical correlate with ultimate freedom from disease (includes the contribution of salvage surgery) was extent of disease. The 5-year ultimate freedom from disease was 87±5% for T1/T2N0, 78±10% for T3N0 (15% salvaged by surgery), and 43±10% for either T4N0 or any N+ lesions (P<0.001, Tarone-Ware). There was no difference between planned vs. expectant surgery (5-year ultimate NED: 67±11% planned surgery vs. 73±5% expectant surgery). The most important correlate with late toxicity was a history of major pelvic surgery (surgical vs. non-surgical group: P=0.013, Fisher's exact test, two-tailed summation). Thirty-three additional malignancies have been seen in 26 patients. The most common additional malignancies were gynecologic (nine cases), head and neck (six cases), and lung cancer (five cases). Conclusions: For T1/T2N0 dve cases). Conclusions: For T1/T2N0 disease, moderate doses of radiation combined with chemotherapy provided adequate treatment. T4N0 and N+ lesions are the most appropriate candidates for investigational protocols evaluating dose intensification. T3N0 tumors may also be appropriate for investigation; however, dose intensification may ultimately prove counterproductive if the cure rate is not improved and salvage surgery is rendered more difficult. The volume of irradiated small bowel should be minimized for patients who have a past history of major pelvic surgery or who (because of locally advanced tumors) may need salvage surgery in the future. Because of the occurrence of additional malignancy, patients with anal cancer should receive general oncologic screening in long-term follow-up

Abstract in english Objective: Neurological metastases secondary to urological tumors account for 12% overall. The ones derived from germ cells testicular tumors are exceptional in the age of cisplatin. Methods: We report one case of mixed germ cell tumor in a 49-year-old male patient treated with systemic chemotherapy [...] during 18 months before presenting with severe central and peripheral neurological symptoms leading to death due to massive cerebral hemorrhage. Results: We describe three types of presentation of cerebral metastases in patients with testicular cancer. Type 1 present synchronically with the primary tumor. Type 2 are diagnosed after a period of remission after conventional cytostatic treatment. Type 3 metastases are diagnosed during the course of the disease and its treatment. Conclusions: Except unique metastases classified in groups I and 2, which are susceptible of surgery or radiosurgery, in which in response may be expected; the rest of lesions secondary to germ cell tumors have an ominous prognosis and outcomes, with short survivals.

    Full Text Available OBJETIVO: Para evaluar la infección y obtener el estado adulto del cestodos, se buscó reproducir la equinococosis en perros a partir de quiste hidatídico de origen porcino. MÉTODOS: Se formaron 2 grupos, uno de 5 y otro de 3 perros, a cada animal del grupo experimental se le dió 2 g de membrana germinativa de quíste hidatídico fértil por vía oral, el segundo grupo fue testigo. Ambos grupos fueron evaluados clínica, serológica y parasitológicamente, en el grupo experimental se sacrificó un animal el día 35 de la infección y los siguientes cada 5 dias hasta el 55, en el segundo grupo todos se sacrificaron el día 55. Se observaron huevos del cestodos en heces a partir del dia 51 postinfección. La evaluación morfológica se realizó mediante observación microscópica del raspado de mucosa intestinal. RESULTADOS: De 50 cestodos analizados, 10 de cada uno de los perros infectados, 49 (98% presentaron 3 proglótidos y 1 (2% tenía 4; 18 (36% de los cestodos presentaban un proglótido grávido. La longitud de los estróbilos varió de 1,6 a 2,6 mm. El número promedio de los ganchos largos y cortos fue de 31 y 34 respectivamente. La longitud de los ganchos largos varió entre 0,081 y 0,09 mm, los ganchos cortos fluctuaron entre 0,034 y 0,041 mm. En los perros evaluados clínicamente, el número de leucocitos y la cantidad de proteínas plasmáticas fue significativamente mayor en el grupo testigo (P < 0,05; la cantidad de alfa globulinas fue mayor en el grupo infectado (P < 0,05. CONCLUSIONES: Los resultados permiten confirmar el ciclo perro-cerdo y una infección subclínica en los huéspedes definitivos, lo que dificulta su diagnóstico y control en una especie intimamente relacionada con el hombre.

El tratamiento es la cirugía en los funcional y la punción aspirativa en los no funcionales, que suelen solucionarse con una sola o a veces en otra repetida, dejándose para la cirugía los pocos recurrentes. Presentamos el caso de comportamiento recurrente y su evolución natural, donde la paciente rechaza la cirugía, siendo necesarias punciones repetidas. Después de 10 años no se ha malignizado ni cambiado su estado funcional, siendo necesario realizar repetidas punciones aspirativas cada 2-3 meses por molestias locales. Abstract in english The parathyroid cyst is a very infrequent entity, so much so that only round about 200 cases have been described up to now. It can be functional and non-functional.

Surgery is the treatment for functional cysts and the puncture aspiration for non- functional, the fact that they use to get solved with only one but sometimes is necessary to repeated it, even more than one time, keeping for the surgery when recurrent. We presented a clinical case of recurrent parathyroid cyst and his natural evolution, due to patient rejects surgery, being necessary repeated punctures. It hasn't become malignant after 10 years and his functional status wasn't changed, being necessary to accomplish repeated punctures aspirations each 2-3 months for local bothers.

  18. Epidermoid cyst in the cerebellopontine angle cistern presenting as trigeminal neuralgia

    International Nuclear Information System (INIS)

    This 29-year-old male had been suffering from left trigeminal neuralgia one year prior to admission. Admission was prompted by the development of pain in the third division of the left trigeminal nerve. Physical and neurological examinations were not remarkable except for the facial pain. The orbicularis oculi reflex showed delayed latency of R1 on the affected side. CT scans performed pre- and post-contrast enhancement revealed a low density area in the left cerebellopontine angle cistern. Metrizamide CT cisternography clearly revealed the margin of the lesion as the contrast media did not enter into the low density area. A left suboccipital craniectomy was performed. The trigeminal nerve was surrounded by a thin-capsulated mass and cholesteatoma materials. Histological diagnosis was epidermoid cyst. Since this surgical procedure, the trigeminal neuralgia has not recurred for one year. Without objective neurological deficits, it is difficult to distinguish symptomatic trigeminal from idiopathic neuralgia. Therefore, minor change of the orbicularis oculi reflex should help in objectively detecting dysfunction of the trigeminal nerve. Metrizamide CT cisternography is also useful in diagnosis of cystic lesions. (author)

    Primary testicular diffuse large B cell lymphoma (PTL) is an aggressive malignancy that occurs in the immune-privileged anatomical site of the testis. We have previously shown that structural genomic rearrangements involving the MHC class II transactivator CIITA and programmed death ligands (PDLs) 1 and 2 are frequent across multiple B cell lymphoma entities. Specifically in PTL, we found rearrangements in the PDL locus by fluorescence in situ hybridization (FISH). However, breakpoint anatomy and rearrangement partners were undetermined, while CIITA rearrangements had not been reported previously in PTL. Here, we performed bacterial artificial chromosome capture sequencing on three archival, formalin-fixed, paraffin-embedded tissue biopsies, interrogating 20 known rearrangement hotspots in B cell lymphomas. We report novel CIITA, FOXP1 and PDL rearrangements involving IGHG4, FLJ45248, RFX3, SMARCA2 and SNX29. Moreover, we present immunohistochemistry data supporting the association between PDL rearrangements and increased protein expression. Finally, using FISH, we show that CIITA (8/82; 10%) and FOXP1 (5/74; 7%) rearrangements are recurrent in PTL. In summary, we describe rearrangement frequencies and novel rearrangement partners of the CIITA, FOXP1 and PDL loci at base-pair resolution in a rare, aggressive lymphoma. Our data suggest immune-checkpoint inhibitor therapy as a promising intervention for PTL patients harbouring PDL rearrangements. Copyright © 2015 Pathological Society of Great Britain and Ireland.

    Testicular cancer (TC) is currently the most common malignant solid tumour in Caucasian males aged 15-39 years. Epidemiological evidence suggests that its onset may be due to an imbalance in the action of steroidal sex hormones and their receptors. A faulty androgen receptor signalling pathway can, in fact, cause various male reproductive disorders. The androgen receptor (AR) gene has two polymorphic segments consisting of CAG and GGC repeats. The length of CAG repeats has been shown to affect the regulation of AR activity. In our study, we used fragment analysis to evaluate the AR gene repeats of 302 TC patients and 322 controls, to establish if there is any association between repeat number and TC. This study of the largest Italian caseload investigated to date highlighted three particularly significant aspects. First, a CAG repeat number of ?25 may be considered a risk factor for the onset of TC, given its greater frequency in patients in comparison with controls. This difference became significant for the non-seminoma group. Second, men with CAG repeats below 21 or above 24 were found to have a, respectively, 50 and 76% higher risk of TC than those with CAG 21-24, suggesting that these too can be considered a risk factor for TC. Finally, stage II patients were more likely to have a CAG repeat number 24 than stage I patients. PMID:25180665

    Both staging and surgery in testicular cancer are thoroughly analysed. Extensive experiences from various authors are reported and compared. The essentials for staging are suggested and a new detailed stage grouping is proposed. The role of surgery in diagnosis, staging and therapy is examined. It is stressed that in non-seminomas, retroperitoneal lymph node dissection is not only a staging procedure, but it may be also a curative operation in several cases of patients with lymph node metastases and a prospective randomized clinical trial is advocated in order to clarify the usefulness of adjunctive chemotherapy in these cases. Surgery is also useful as adjuvant to chemotherapy in several patients with advanced non-seminomas and it is underlined that it should be undertaken early, after only 2 or 3 cycles of chemotherapy, in order to avoid the strong fibrosis that often occurs after long-term chemotherapy and which makes surgical dissection very difficult or even impossible. Lastly, even if extensive, surgery seems to be a safe procedure in these young patients. PMID:7007053

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

    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.

    Full Text Available BACKGROUND: Advances in oncology have greatly improved the prognosis of testicular cancer. In developing countries, however, the outcome is still poor. PATIENTS AND METHODS: Twenty-four patients managed for testicular cancer at two centres (University of Nigeria Teaching Hospital, Enugu, Nigeria, an [...] d JAMA Urological Clinic, Enugu) between April 1984 and March 2003 were prospectively studied. Histopathological data were obtained in all cases. RESULTS: Peak age incidence was 20 - 29 years. Testicular swelling was the principal complaint in 23 patients. The mean interval between onset of symptoms and presentation was 5.3 months. Two patients (8.3%) presented with stage 1 disease, 7 (29.2%) with stage 2, 7 (29.2%) with stage 3, and 8 (33.3%) with stage 4. Seventy-five per cent of tumours were right-sided, and 25% were left-sided. Treatment consisted of radical orchidectomy in all patients and cisplatin-based chemotherapy and radiotherapy in some patients. One patient with a tumour in an intra-abdominal testis underwent laparotomy. The most common histological types were seminoma and embryonal carcinoma. A fifth of the patients died, while half were lost to follow-up. The mean follow-up period was 9 months. CONCLUSION: Morbidity and mortality of testicular cancer is high in developing countries. Late presentation, poverty, paucity of resources and the high cost of newer imaging modalities and treatment are major challenges to management. Better health funding and education regarding testicular self-examination is essential.

    To characterize the sonographic findings of torsed testicular appendages and to evaluate the sonographic findings in making erroneous diagnosis of epididymitis or torsion of testis in prepubertal children. From June 2010 to November 2012, we retrospectively analyzed the duplex sonography of fifteen children with torsion of testicular appendages. The presence or absence of the extratesticular nodule and secondary inflammatory changes were evaluated. Six patients had follow-up sonography and two patients underwent surgery. Sonography demonstrated the extratesticular nodule in 13 (87%) children. Four of these 13 children were misdiagnosed as epididymitis due to imperceptions of the nodule. Out of remaining two (13%) children without the nodule, one mimicked epididymitis and the other was misdiagnosed as torsion of testis. Secondary inflammatory changes included enlarged epididymis in 14 children (93%), scrotal wall edema in 11 (73%), hydrocele in 10 (67%), and enlarged testis in 3 (20%). Ultrasonographic findings of secondary inflammatory changes in the absence or imperception of the nodules for epididymo-testicular groove or epididymal head may suggest an erroneous diagnosis of epididymitis or torsion of testis in children with torsed testicular appendages. Meticulous evaluation for the nodule is important when differentiating the torsed testicular appendages from the two entities of prepubertal children.

  17. Studies on the influence of radiation and chemotherapy on pituitary-testicular axis in patients with testicular tumor

    International Nuclear Information System (INIS)

    Radiation and chemotherapy have been known as the highly effective treatment of patients with testicular tumor. To evaluate the influences of the therapies on pituitary-testicular axis, plasma FSH, LH and testosterone were determined by radioimmunoassay in 60 patients with testicular tumor before and after 1 to 102 months in the completion of radiation and chemotherapy. The results were summarized as follows: 1) In 10 out of 24 patients, plasma FSH and LH levels significantly increased within 20 months after 2,100 - 4,500 rad/3 - 6 weeks of radiation therapy. 2) In combination chromotherapy popularly used for testicular tumor, plasma FSH and LH in 8 of 22 patients markedly elevated within 20 months after the treatment. 3) The elevated gonadotropins returned to normal levels in approximately 50 months in patients received radiation or chemotherapy. 4) Plasma testosterone revealed normal levels in any therapeutic programs employed in the present study. 5) From the results of Gn-RH test, the pituitary gland seemed to have normal function. 6) Plasma testosterone showed incomplete response to hCG stimulation after 1 to 35 months of radiation or chemotherapy. Therefore, it was suggested that radiation and chemotherapy for the treatment of testicular tumor may impair not only seminiferous tubules but also Leydig cell for a couple of years. (author)

    The authors report a work aimed at assessing the feasibility and toxicity of a re-irradiation treatment in stereotactic conditions using CyberKnife and cetuximab in the case of local relapses of epidermoid cancers of the ORL sphere. Thirty three patients have been submitted to this treatment between June 2007 and April 2009. Although six patients died by six months, this treatment seems to be a good alternative, and presents an acceptable short-term toxicity. Further studies are needed to compare this technique to other therapeutic techniques, and to assess the risk of long term complications. Short communication

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

    Rahman, M S; Takemura, A; Takano, K

    2001-06-01

    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. PMID:11399470

  5. Radionuclide diagnostics of testicular blood flow changes in varicocele

    International Nuclear Information System (INIS)

    Gamma camera scintigraphy is performed in 82 patients presenting varicocele associated with fertility and spermatogenesis impairment. A new method of quantitative and semi-quantitative assessment of testicular blood and vascularity is used to reveal changes in testicular blood flow due to varicocele. The obtained radionuclide indices are typical of the disease, and their numerical values illustrate the changes in the blood vessels and capillary tissue vascularity. The varicocele curve proper has a very characteristic pattern, and enables different diagnosis with focal epididymitis of the head of epididyms. The radionuclide indices and their values are also used to assess the severity of the disease. 5 refs., 4 figs. (orig.)

  7. Review of photodynamic therapy with 5-methyl aminolevulinate in actinic keratosis, epidermoid carcinoma and basal cell carcinoma

    International Nuclear Information System (INIS)

    A bibliographic review was conduced on the use of 5-methyl aminolevulinate in dermatology, specifically in the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma. The basic fundamentals of photodynamic therapy are described. The preparation and method of use of photodynamic therapy with 5-methyl aminolevulinate (MAL-PDT) are detailed. The clinical studies that were realized with photodynamic therapy for the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma are mentioned. Different photo-inducible agents and other current therapeutic options of first-line are compared. The MAL-PDT has have the advantage of to present less side effects and the same have been more tolerable than liquid nitrogen and 5 fluorouracil. The MAL-PDT has been considered as an effective option for the treatment of Bowen's disease. Invasive epidermoid carcinoma has existed without evidence to support the routine use of this therapeutic. For superficial basal cell carcinoma, the MAL-PDT has presented a high cure rate and transient and manageable side effects in extensive and multiple lesions. The MAL-PDT has been an effective and safe treatment in patients with basal cell carcinoma, for those with less depth of 2mm. The MAL-PDT could play an important role in the field of prevention with immunosuppressed patients, particularly, those that have required transplant and its immunosuppression has been pharmacological. The use or not of the MAL-PDT, should be evaluated individually for each patient and to have suitable characteristics for each disease that was cited in this review. The photodynamic therapy with 5-methyl aminolevulinate has been a therapeutic modality of considerable economy, however, it should be evaluated in the context of number of inquiries and side effects that have offered other therapeutic modalities

  8. Testicular tumors with tumor thrombosis within the inferior vena cava: Two case reports

    International Nuclear Information System (INIS)

    Testicular tumors are almost all malignant tumors and can develop in younger age groups. Testicular tumors are mostly curable, with reported cases of tumor thrombosis within the inferior vena cava being rare. Two patients, aged 35 years and 37 years old complaining of testicular pain and lower abdominal pain were diagnosed with testicular tumors by ultrasound. In addition, tumor thrombus of the inferior vena cava was diagnosed concomitantly at the time of the diagnosis by computed tomography and magnetic resonance imaging. Here, we report testicular tumors accompanied by tumor thrombus, which is an extremely rare finding, with limited reports available. Pathologic diagnoses were seminoma and mixed germ cell tumors, respectively

    Full Text Available This paper reports a case of testicular synovial sarcoma with molecular genetic analysis. A 24-year-old male presented with painless scrotal mass. Ultrasonography showed a heterogeneous mass of 66 mm × 34 mm in size involving the inguinal region. Histological examination of a surgical biopsy showed a grade III monophasic growth pattern of spindle cell proliferation. Immunohistochemical analyses indicated positive staining for pancytokeratine and epithelial membrane antigen. Cytogenetic analysis showed the presence of CYT-SSX1 mutation, and CT scan showed non-specific pleural micro-nodules with a size of 7.5 mm. The patient had an extended left orchidectomy but was lost to follow-up for 1 year. A local recurrent scrotal mass of 32 mm × 25 mm, multiple inguinal lymph nodes, and increased pleural nodules, which were con? rmed by histological examination, were treated with three cycles of adriamycine and ifosfamide chemotherapy, surgical resection, and radiotherapy with complete response. After 3 months, the patient developed local recurrence and pulmonary metastases that did not respond to second-line chemotherapy based on gemcitabine and paclitaxel. The patient had dyspnea at the time of this writing and chest pain, and is under third-line chemotherapy based on Deticene after 30 months of following up. This patient died on November 16, 2012 after a resperatory failure and malignant plural effusion. Synovial sarcoma should be considered in the differential diagnosis of soft tissue tumor and it should be aggressively treated to improve prognosis. Although our patient has shown numerous factors of bad prognosis, he has had a relatively long survival time.

Clínicamente se caracterizan por un cuadro mielopático progresivo, asociado o no a crisis radiculares. Para su diagnóstico radiológico las técnicas de resonancia magnética actuales posibilitan definirlos adecu [...] adamente y conocer su localización topográfica. Los antecedentes patológicos del paciente son esenciales para establecer se etiología encontrándose en muchos casos una historia de trauma espinal, cirugía y menos frecuentemente anomalías congénitas asociadas. El tratamiento en la mayoría de los casos es quirúrgico. Caso clínico. Presentamos el caso de un paciente de 35 años con antecedentes de una hemisección medular dorsal por arma blanca hace dos años. Evolutivamente se deterioran sus funciones motoras presentándose con una paraparesia espástica. Los estudios radiológicos mostraron la presencia de la lesión quística extradural comprimiendo el cordón medular a nivel dorsal (D3-D4). Se realizó cirugía descompresiva y se identificó un desgarro meníngeo a ese nivel que fue suturado. La evolución postoperatoria fue satisfactoria. Conclusiones. El tratamiento quirúrgico efectivo de estas lesiones está dado por la detección del defecto meníngeo y su cierre. Abstract in english Introduction. Extradural arachnoid spinal cysts are unfrequent lesions that are associated with spinal trauma, surgery and less frequently with congenital anomalies. The clinical manifestations are similar to those seen with other compressive spinal cord lesions. Magnetic resonance techniques allow [...] to diagnose correctly this pathology and to define its thopographic situation. The pathologic history of the patient is essencial to establish the ethiology. Surgery is the elective treatment in most cases. Clinical case. The patient is a 35 years old man who has a medical history of penetrating spinal trauma two years ago. In that instance he suffered an unilateral spinal cord section at D2-D3 level with the corresponding Brown Sequard syndrome. A small wound was detected at the skin dorsal level and it was closed without difficulties. At the beginning, he improved his motor right leg function with rehabilitation and vitamins. After two years of good recovery he came to our hospital suffering a neurological deterioration of six months of evolution. The physical examination revealed an spastic paraparesis. Magnetic resonance was performed demonstrating a cystic extradural collection compressing the spinal cord at D3-D4 level. Surgical decompressive treatment allowed to excise the cyst and it was possible to define a dural tear that was closed successfully. The outcome was good with restoration of the initial motor function that he had after the spinal trauma. Conclusions. Surgical management of postraumatic epidural arachnoid spinal cyst allows to detect the meningeal tear and to close it, which is highly effective on these kinds of lesions.

Analisar, retrospectivament [...] e, pacientes com carcinoma epidermóide do esôfago tratados pelo Grupo de Cirurgia do Esôfago, Estômago e Intestino Delgado (GCEEID) do Hospital de Clínicas de Porto Alegre (HCPA), no período de janeiro/88 a junho/95, os quais tinham neoplasias associadas ao CEE. PACIENTES E MÉTODOS. Dentre os 261 pacientes estudados, 19 (7,28%) tinham neoplasia associada ao CEE. Dez pacientes apresentaram tumores sincrônicos e 9, metacrônicos. O sexo predominante foi o masculino, com 17 casos. A média de idade ficou em 62,52 anos no momento do diagnóstico da neoplasia esofágica. RESULTADOS. Os tumores aerodigestivos, na sua totalidade carcinomas escamosos, representaram o tipo histológico predominante da neoplasia associada em 68,42% dos casos. O sítio mais freqüente da neoplasia aerodigestiva associada foi a árvore respiratória (53,8%), seguido da cavidade oral e orofaringe (23%) e laringe (23%). Dos 19 pacientes, 12 eram tabagistas e nove ingeriam bebidas alcoólicas regularmente. Para o tratamento do CEE, optou-se por cirurgia em seis pacientes. A neoplasia associada foi tratada com cirurgia radical em 11 pacientes e radioterapia em cinco. Surpreendentemente, foram diagnosticados quatro casos (21%) de adenocarcinomas gástricos associados ao CEE, tratados com cirurgia radical em três pacientes. CONCLUSÃO. Os autores ressaltam a importância do estadiamento criterioso dos pacientes com CEE devido a associação significativa com outras neoplasias, principalmente com tumores aerodigestivos. Alertam para o seguimento desses pacientes e discutem a possibilidade de fatores de risco comuns: fumo e álcool. Nesta casuística, encontrou-se associação importante com neoplasias gástricas. Abstract in english INTRODUCTION. The esophageal epidermoid cancer has an important association with aerodigestive tract neoplasms and possibly share the same risk factors. Furthermore, other neoplasms can be associated with esophagus cancer. OBJECTIVE. To analyze retrospectively the patients with esophageal epidermoid [...] cancer (EEC) and associated neoplasms, treated by the Esophagus Stomach and Small Intestine Group of Surgery at Hospital de Clinicas de Porto Alegre from January 1988 to June 1995. PATIENTS AND METHODS. Nineteen (7.28%) of the 261 studied patients had associated neoplasms to the EEC. Ten patients presented synchronic tumours and 9 metachronic ones. The predominant sex was the masculine with 17 cases. The mean age was 62.52 years in the moment of the esophageal cancer diagnostic. RESULTS. The aerodigestive tumours, squamous carcinomas in totality, represented the predominant associated neoplasm histological type in 68.42% of the cases. The most frequent associated aerodigestive tumours site was the respiratory tract (53.8%), followed by the oral cavity and oropharynx (23%) and larynx (23%). In our sample, twelve patients were smokers and 9 were alcohol abusers. In relation to the EEC treatment, surgery was performed in 6 patients. The associated neoplasm was treated with radical surgery in 11 patients and radiotherapy in 5. Surprisingly 4 cases (21%) of gastric adenocarcinoma associated to the EEC were diagnosed, treated with radical surgery in 3 patients. CONCLUSION. The authors call attention to the importance of a criterial staging as well as the follow up in patients with EEC owing to the significant association with others neoplasms, principally with aerodigestive tumours, and discuss the common risk factors possibility: tobacco and alcohol use.

  13. Epidermoid carcinoma of the anal canal. A series of 276 cases

    International Nuclear Information System (INIS)

    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 chemotherapymal 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.

  15. Leydig-cell function in children after direct testicular irradiation for acute lymphoblastic leukemia

    International Nuclear Information System (INIS)

    To assess the effect of testicular irradiation on testicular endocrine function, we studied 12 boys with acute lymphoblastic leukemia who had been treated with direct testicular irradiation 10 months to 8 1/2 years earlier. Insufficient Leydig-cell function, manifested by a low response of plasma testosterone to chorionic gonadotropin or an increased basal level of plasma luteinizing hormone (or both), was observed in 10 patients, 7 of whom were pubertal. Two of these patients had a compensated testicular endocrine insufficiency with only high plasma concentrations of luteinizing hormone. Testosterone secretion was severely impaired in three pubertal boys studied more than four years after testicular irradiation. A diminished testicular volume indicating tubular atrophy was found in all pubertal patients, including three who had not received cyclophosphamide or cytarabine. These data indicate that testosterone insufficiency is a frequent complication of testicular irradiation, although some patients continue to have Leydig-cell activity for several years after therapy

  3. Testicular descent: INSL3, testosterone, genes and the intrauterine milieu

    Complete testicular descent is a sign of, and a prerequisite for, normal testicular function in adult life. The process of testis descent is dependent on gubernacular growth and reorganization, which is regulated by the Leydig cell hormones insulin-like peptide 3 (INSL3) and testosterone. Investigation of the role of INSL3 and its receptor, relaxin-family peptide receptor 2 (RXFP2), has contributed substantially to our understanding of the hormonal control of testicular descent. Cryptorchidism is a common congenital malformation, which is seen in 2–9% of newborn boys, and confers an increased risk of infertility and testicular cancer in adulthood. Although some cases of isolated cryptorchidism in humans can be ascribed to known genetic defects, such as mutations in INSL3 or RXFP2, the cause of cryptorchidism remains unknown in most patients. Several animal and human studies are currently underway to test the hypothesis that in utero factors, including environmental and maternal lifestyle factors, may be involved in the etiology of cryptorchidism. Overall, the etiology of isolated cryptorchidism seems to be complex and multifactorial, involving both genetic and nongenetic components.

    Genomic instability is a feature of germ cell tumours. The pituitary-tumour-transforming-gene 1 (PTTG1) is the major effector of chromosome segregation during mitosis, protecting the cell from aneuploidy. The protein expression of this gene has been evaluated in testicular tumours by immunohistochemistry. Formalin-fixed and paraffin-embedded specimens of testicular tissues from 83 patients undergoing therapeutic orchidectomy for seminomas (n = 53), embryonal carcinoma (n = 10), yolk sac tumour (n = 10) and teratoma (n = 10) were examined. Seminoma was associated with in situ carcinoma (CIS) in 23 samples. PTTG1 immunostaining was performed using rabbit anti-PTTG1 as a primary antibody. In CIS, only isolated cells showed nuclear staining for PTTG1. In the peripheral area of seminoma, PTTG1 was mostly detected as localised in the nucleus; in the central area of seminoma, PTTG1 staining was more intense in cytoplasm. PTTG1-positive cells were also present in the areas of seminoma infiltration. On the other hand, in embryonal carcinoma, cells had a diffuse positive immunostaining, mainly cytoplasmatic, while we did not observe an expression of PTTG1 in yolk sac tumour and mature teratoma. We firstly identified the PTTG1 expression pattern in normal testis, CIS and testicular cancer. Further investigation is needed to clarify the functional activity of PTTG1 in testicular oncogenesis.

  5. Feasibility of sentinel node lymphoscintigraphy in stage I testicular cancer

    International Nuclear Information System (INIS)

    The aim of this study was to investigate the feasibility of lymphoscintigraphy for sentinel node identification in testicular cancer. Five patients with clinical stage I testicular cancer were prospectively included. A single dose of technetium-99m nanocolloid (mean dose 99 MBq, volume 0.2 ml) was injected into the funiculus in the first patient and into the testicular parenchyma in the following four patients. Dynamic lymphoscintigraphy was performed over 10 min, followed by early and late static images after 15 min and 2 to 24 h, respectively. Lymphoscintigraphy was followed by laparoscopic sentinel node biopsy on the same day in the last two patients using patent blue dye and an endoscopic gamma probe. The funicular administration route showed five hot spots in the right inguinal region after 2 h. Intratesticular administration resulted in sentinel node visualisation in three of the four patients. Dynamic images showed afferent lymphatic vessels to one sentinel node in the left para-aortic region in two patients and two sentinel nodes in the left para-aortic region in another patient. Sentinel nodes were intraoperatively identified in one of two patients who underwent laparoscopic exploration. It is concluded that lymphoscintigraphy for sentinel node identification is feasible in stage I testicular cancer using intratesticular radiocolloid administration. (orig.)

En el laboratorio se verificó la fertilidad (presencia o ausencia de protoescólices) de los quistes obtenidos y su viabilidad mediante la tinción con azul de Trypán. Sobre el 75% de los bovinos procedía de las regiones ganaderas del Sur de Chile. En las 6 regiones se constató un promedio de alrededor de un 16% de positividad a hidatidosis. El 100% de los animales mayores (vacas, toros y bueyes) y sólo el 9,1% de los animales jóvenes (vaquillas y novillos) tenía hidatidosis. 74% fueron quistes pulmonares, 25,6% hepáticos y 0,4% esplénicos. A mayor edad de los bovinos, aumentaban porcentualmente los quistes hepáticos. En los animales jóvenes el 67% de los quistes tenía un diámetro inferior a 10 mm siendo todos infértiles. En los animales mayores todos los quistes tenían un diámetro superior a 10 mm; en los animales jóvenes un 32,9% alcanzaba ese diámetro. De todos los quistes con un diámetro superior a 10 mm, 39,4% eran fértiles, 17,6% infértiles y 43% estaban alterados.

  8. Association between testicular dysgenesis syndrome (TDS) and testicular neoplasia: evidence from 20 adult patients with signs of maldevelopment of the testis

    Skakkebæk, Niels Erik; Holm, Mette

    2003-01-01

    Based on a well established association between testicular cancer and undescended testis and more recent publications on epidemiological links between these disorders and male infertility, we proposed the existence of a testicular dysgenesis syndrome (TDS). In most cases TDS presents with impaired spermatogenesis, only in rare cases the full range of its signs, including genital malformations and testicular cancer can be seen in one patient. In order to further corroborate our hypothesis about the presence of testicular dysgenesis in patients with testicular abnormalities, we decided to re-analyse recent testicular biopsies derived from patients with infertility, hypospadias and undescended testis. We searched for histological signs of testicular dysgenesis: microliths, Sertoli-cell-only tubules, immature seminiferous tubules with undifferentiated Sertoli cells, and tubules containing carcinoma in situ (CIS) cells. We identified 20 patients who fulfilled the histological criteria for testicular dysgenesis, 9 of whom were diagnosed with uni- or bilateral testicular germ cell neoplasia, and the remaining ones with subfertility. The presence of CIS was detected in 5 patients (3 of them with overt contralateral germ cell tumours). In all but one of the CIS cases, at least one additional sign of testicular dysgenesis was detected. Clinical records of all patients were subsequently analysed. The majority of cases had oligozoospermia or azoospermia. Their reproductive hormone profiles correlated with the results of semen sampling and testicular histology. In conclusion, our study of 20 patients with various reproductive abnormalities provided evidence that TDS is a real clinical entity. We speculate that most of these abnormalities are caused by adverse environmental effects rather than specific gene mutations.

    Full Text Available The testicular and epididymal parameters of Sahel bucks in the humid zone of Nigeria was investigated. Twenty goats (30-54 months weighing 23.48-32.03kg were used for the experiment. The scrotal circumference of the buck was measured. The bucks were then slaughtered and the testicles as well as the epididymides collected. The testicular weight, testicular diameter, testicular length and epididymal length were measured using a non-stretchable measuring tape. These parameters were correlated with one another and the values of the right testis and epididymis were compared with those of the left. The scrotal circumference was positively correlated with the testicular weight (r = 0.769, PFueron investigados los parámetros testicular y epidídimario de las cabras Sahel en la zona húmeda de Nigeria. Se utilizaron para el experimento 20 cabras (30-54 meses con un peso entre 23,48-32,03kg. Se midió la circunferencia escrotal de las cabras. Los animales fueron sacrificados y se recolectaron los testículos, así como el epidídimo de cada uno. Fueron medidos el peso de los testículos, diámetro testicular, longitudes testicular y epididimaria utilizando una cinta métrica no extensible. Estos parámetros fueron correlacionados entre sí y los valores obtenidos a cada lado de testículos y epidídimos fueron comparados entre sí. La circunferencia escrotal se correlacionó positivamente con el peso testicular (r = 0,769, P <0,01, diámetro testicular (r = 0,827, P <0,01, longitud testicular (r = 0,671, P <0,05 y la longitud del epidídimo (r = 0,664, P <0,05.

The aim of our study was to evaluate the rate of perioperative complications and recurrences after this modified surgical procedure. Materials and methods: We conducted a retrospective analysis of a cohort patients undergoing resection of thyroglossal duct cyst with the modified surgical procedure between March 2003 and March 2011. Surgery was performed by a head and neck surgeon of Foundation Cardioinfantil, Bogotá. Results: 43 patients who met the inclusion criteria were included in the study. Median follow-up was 11 months and the rate of complications was 6.9% (n = 3). There were 2 foreign body granulomas and one mucocele, which was considered a recurrence (2.3%). Discussion: We did not find an increase in the rate of perioperative complications with the modified surgical technique. Recurrence of the disease is similar to the data reported in the literature and we believe that the proposed surgical procedure can be a safe and viable option.

She had a history of hysterectomy three years ago. Abdominal ultrasound and CAT scan showed a giant cystic lesion of 15 x 8 x 12 cm that occupied a great portion of the abdomen and pelvis. After a partial resection and marsupialization, she was refereed to surgery due to an early relapse of the cyst. She was operated again, performing a complete cyst excision and bilateral anexectomy, with a good postoperative evolution. Pathology confirmed the diagnosis of a simple omental cyst. The unilocular feature of the lesion is characteristic of omental cysts. However, due to the pelvic location and dimensions, the differential diagnosis must be made with benign cystic mesothelioma, that had a high rate of relapse and may become malignant

    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.

    Full Text Available Este estudo foi realizado com a finalidade de avaliar a evolução das secreções hormonais e do epitélio seminífero em touros da raça Angus de 10 a 38 semanas de idade. Foram castrados 1 a 5 animais em intervalos de quatro semanas (total de 25 touros para coleta de amostras do parênquima testicular e do plasma sanguíneo. As variáveis relacionadas ao crescimento testicular, aos aspectos quantitativos da espermatogênese e aos níveis hormonais foram transformadas em logaritmo e avaliadas por meio de análise de variância. O diâmetro dos testículos e túbulos seminíferos e o peso testicular apresentaram variações mais acentuadas após 26 semanas de idade. A porcentagem do parênquima testicular ocupado pelos túbulos seminíferos aumentou de 49,3 para 75,2% durante o experimento. A maioria dos túbulos (>90% apresentou-se com células de Sertoli somente entre 10 e 14 semanas, mas na 18ª (13,8±1,7% e 22ª semanas (19±1%, o número de túbulos com gonócitos e espermatogônias aumentou em relação às semanas iniciais. Espermatogônias intermediárias e B predominaram na 26ª semana (24,5±8,2% e a porcentagem de túbulos com espermatócitos foi mais elevada na 30ª semana (42,3±9,9%. Espermátides arredondadas foram detectadas partir da 26ª semana e, na 38ª semana, 62,3±1,5% dos túbulos seminíferos continham espermátides alongadas ou maduras. As variações mais acentuadas no crescimento testicular e, principalmente, no peso testicular após as 26 semanas coincidiram com o estabelecimento da meiose, com as alterações morfológicas do núcleo e nucléolo das células de Sertoli (indicativos do processo de diferenciação das mesmas, com os níveis reduzidos de androstenediona e os incrementos significativos de testosterona e estradiol 17beta. As associações entre o crescimento testicular e os níveis de FSH e LH na circulação periférica foram menos evidentes.This study aimed to evaluate changes in hormone secretion and in seminiferous epithelium of Angus bulls between 10 and 38 weeks of age. Samples of testicular parenchyma and blood were collected from 25 animals castrated in 4 week intervals. Traits associated to testicular development and quantitative aspects of spermatogenesis and hormonal concentrations were transformed by logarithm before analyses of variance. Changes in testis and seminiferous tubule diameter and testis weight were more pronounced after 26 weeks of age. The percentage of testicular parenchyma occupied by seminiferous tubules increased from 49.3 to 75.2% from 10 to 38 weeks. Most tubules (>90% had only Sertoli cells at 10 and 14 weeks, but the number of tubules with gonocytes and A spermatogonia increased at 18 (13.8±1.7% and 22 weeks (19±1%. Tubules with B and intermediate spermatogonia became predominant at 26 weeks (24.5±8.2% and those with spermatocytes as the most advanced germ cell type were more evident at 30 weeks (42.3±9.9%. Round spermatids were detected at 26 weeks and at 38 weeks of age, 62.3±1.5% of all tubules had either elongate or mature spermatids. Variations in testis growth (specially testis weight after 26 weeks were coincident with the establishment of meiosis in the seminiferous tubules, morphological alterations in nucleus and nucleolus of the Sertoli cells (indicators of Sertoli cell differentiation, lower levels of androstenedione and significant increases in testosterone and estradiol 17beta. Associations between testis development and concentrations of FSH and LH were less evident.

    Full Text Available Los pesticidas organofosforados son un problema de salud mundial, especialmente para los trabajadores agrícolas, calculados en alrededor de 2.600 millones de personas en el año 2001. Se conoce muy poco sobre el daño reproductivo en el varón provocado por estos agentes. El efecto agudo de Malathion e [...] n inyección intraperitoneal única, de 1/12 la LD50 en ratón fue analizado 1,8,16,35 y 40 días después de la inyección, evaluando proliferación y apoptosis de las células espermatogénicas y daño de las células de Sertoli, estudiados por la detección inmunocitoquímica de citoqueratina (usando CK-18). Los resultados muestran disminución del número de células germinales, seguida de una proliferación compensatoria de espermatogonias al día 16 (como lo muestra la incorporación de timidina H3 al testículo), aumento de la tasa de apoptosis (especialmente de espermatogonias y espermatocitos en preleptoteno), la reactividad a CK-18 de las células de Sertoli que denota alteración de ellas, probablemente asociada a daño de la línea germinal que se observa en los animales tratados a intervalos cortos. El malathion es genotóxico para las células somáticas como lo demuestra el test de micronúcleo. En consecuencia, se postula que junto al proceso de espermatogénesis, son afectadas las células de Sertoli y de Leydig. La recuperación morfológica del testículo se observa sólo a intervalos largos Abstract in english Organophosphorous pesticides are a healh problem worldwide, mostly for agroworkers, which are around 2600 millions of person in the year 2001. Little is known about male reproductive damage elicited by these chemicals. The acute effects of malathion (single intraperitoneal injection), 1/12 the LD50 [...] to mice were analyzed at 1, 8, 16, 35 and 40 days after injection, in terms of spermatogenic cell proliferation and apoptosis and of Sertoli cell compromise as revealed by immunocytochemical detection of CK-18 (cytokeratin). The micronuclei test was done to assess for genotoxic activity of the agropesticide. The results showed decreased germ cell number followed by compensatory spermatogonial proliferation by 16 days (as shown by thymidine-H3 testicular uptake), increased apoptotic rate, mainly of spermatogonia, and preleptotene spermatocytes. Sertoli cell reactivity to CK-18, denoting alteration of them, probably due to germ cell damage, was seen in treated mice. Genotoxicity for somatic cells was demonstrated by the micronuclei test. Therefore, it is assumed that Sertoli as well as Leydig cells are affected together with spermatogenesis; recuperation of testicular morphology is seen by longer time intervals
