Quiste epidermoide testicular: una rara entidad de difícil diagnostico preoperatorio / Testicular epidermoid cyst: uncommon lesion of difficult preoperative diagnosis  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Los quistes epidermoides intratesticulares son tumores raros, constituyendo el 1% de todos los tumores testiculares. Se trata de tumoraciones benignas que plantean un difícil diagnóstico diferencial preoperatorio frente a los tumores malignos testiculares. La ausencia de elevación de los marcadores [...] tumorales y la apariencia ecográfica, pueden orientar hacia su diagnóstico preoperatorio y en este caso la cirugía conservadora del testículo. Se presenta el caso de un paciente de 22 años que consulta por una masa en el testículo izquierdo. En este caso, el diagnóstico ecográfico preoperatorio no descartaba otras patologías por lo que se procedió a la realización de orquiectomía inguinal izquierda. Abstract in english Intratesticular epidermoid cysts are rare tumours that constitute one percent of all testicular masses. They are bening lesions that make differential diagnosis from malignant testicular tumours difficult. The absence of serum markers elevation and ultrasound imaging could support these lesions bein [...] g bening epidermoid cysts, and in that case, conservative surgery is adequate. We present the case of a 22 years old patient who complains of a left testicular mass. In this case ultrasound diagnosis was non-specific and a left radical inguinal orchiectomy was performed.

Esplenectomía por quiste esplénico epidermoide  

Directory of Open Access Journals (Sweden)

Full Text Available Los quistes esplénicos son un padecimiento raro. Se manifiestan de forma poco común en la práctica quirúrgica. Se comunica el caso de una paciente con un quiste esplénico diagnosticado en el Departamento de Cirugía General del Hospital General de Zona núm. 4 del IMSS. La mujer, de 21 años de edad, refirió un cuadro clínico con dolor en el hipocondrio izquierdo, que era causado por un tumor de 7 cm de diámetro, aproximadamente. En la TC, se observó que dicho tumor era un quiste esplénico. Se intentó realizar esplenectomía laparoscópica; sin embargo, debido a las adherencias firmes a la pared abdominal y al colon, el procedimiento se llevó a cielo abierto y se hizo esplenectomía total. El estudio histopatológico corroboró el diagnóstico de quiste esplénico epidermoide.

Quiste epidermoide gigante intertesticular / Giant intertesticular epidermoid cyst  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Objetivo: Añadir a la literatura un caso clínico poco frecuente de quiste epidermoide gigante de localización intertesticular, analizando las características histológicas y patológicas del mismo y realizando una revisión de la literatura al respecto. Métodos/Resultados: Presentamos el caso de un var [...] ón de 49 años que consultó por bultoma intraescrotal de 5 años de evolución y lento crecimiento que le ocasionaba molestias por su gran tamaño. Tras exéresis del mismo, el resultado anatomopatológico de la muestra evidenció la presencia de un quiste epidermoide queratinoso de gran tamaño. Conclusiones: Los quistes epidérmicos escrotales superficiales son de frecuente aparición en la práctica clínica, no así los denominados "de inclusión" intraescrotales. Los Quistes Epidermoides son neoformaciones intraepidérmicas, firmes y móviles de crecimiento lento y habitualmente asintomáticos. Están descritos en múltiples localizaciones, incluso en genitales, sin embargo el tamaño de estos a este nivel no suele superar los 5 cm. Abstract in english OBJECTIVE: To report a rare case of a giant epidermoid cyst in an intertesticular localization, analyzing its histological and pathologic features, and to perform a bibliographic review. Methods/Results: We report the case of a 49-year-old male consulting for a slowly growing intra-scrotal mass of f [...] ive years of evolution causing discomfort because of its size. After excision the pathology report showed the presence of a keratoid epidermoid cyst very big in size. Conclusions: Superficial scrotal epidermoid cysts are frequent in clinical practice; that is not the case of the so-called "intra scrotal inclusion cysts". Epidermoid cysts are firm, mobile, slowly growing, generally asymptomatic intra epidermal neoformations. There are descriptions in multiple sites, even the genitalia, nevertheless their size in this location does not usually pass 5 cm.

Abstract in english Epidermoid cysts are benign, uncommon lesions (1% of all intracranial tumors). Their localization is intradiploic in 25% of cases, and exceptionally subtentorial. We report here a rare case of giant intradiploic infratentorial epidermoid cyst. A 74-year old patient presented with recent diplopia and [...] sindrome cerebellar. CT scan and MR imaging revealed a giant osteolytic extradural lesion of the posterior fossa (5,2 cm x 3,8 cm) with a small area of peripheral enhancement after contrast injection. Retrosigmoid suboccipital craniectomy allowed a satisfactory removal of the tumor, followed by an acrylic cranioplasty. The outcome was good. Neuropathological examination confirmed an epidermoid cyst. We review the literature and discuss our case.

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish 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.

Full Text Available SciELO Argentina | Language: Spanish Abstract in english Objective. To present the clinical and radiologic features and surgical results in the management of dermal and epidermal cysts treated in our Institution between 1997 and 2006, Material and method. 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.

Benign Intratesticular Epidermoid Cyst of the Testis: Diagnostic Dilemma  

Directory of Open Access Journals (Sweden)

Full Text Available Intratesticular epidermoid cysts of the testis are rare benign lesions, comprising about 1-2% of all the testicular neoplasms. Clinically it may not be differentiated reliably from the most common malignant testicular tumours and poses a diagnostic dilemma. Majority of the testicular tumours are malignant one, hence accurate diagnosis in benign lesions such as epidermoid cyst is always warranted to avoid unnecessary invasive procedures like orchidectomy. Herein, we present a case of benign, intratesticular epidermoid cyst of the testis in a 30 years old male treated by conservative approach with testicular preservation, avoiding unnecessary orchidectomy.

Se discuten los aspectos microscópicos del caso y se precisa su diagnóstico diferencial con otros tumores del mediastinoThymic cysts are uncommon lesions. Most of them occur in the first decade of life, although they may be present at birth. Other thymic cysts are incidentally discovered in chest X-rays and in autopsy and may be mistaken for malignant tumors. It is reported the case of a woman aged 71 with an old hemorrhage and cholesterol granuloma detected by necropsy study, where a cyst was located in the mediastinum anteroposterior portion.. It was not related to her death, since she died from acute myocardial infarction. The histologic study of the cyst revealed the thymic nature of the process. The microscopic features of the case are discussed and its differential diagnosis is specified in relation to other mediastinal tumors

Pancreatic epidermoid cyst.  

Science.gov (United States)

Epidermoid cyst of intrapancreatic spleen is described but epidermoid cyst occurring in the pancreas itself is not documented. We report a 36-year-old man who presented with abdominal pain radiating to the back. On ultrasonography, a multilocular cyst was seen in the head of the pancreas. Fine-needle aspiration cytology suggested a diagnosis of epidermoid cyst, which was confirmed on histology of the resected specimen. PMID:17558078

High density epidermoid  

International Nuclear Information System (INIS)

A 43-year-old woman presented with ataxia and right-sided cranial nerve palsies. Ten years prior to admission, she was operated for a right cerebellopontine (CP) angle epidermoid. Computed tomography (CT) scan, using GE 9800, showed a large high-density mass without enhancement effect in the right CP angle. The density ranged between 60 and 66 Hounsfield units. Surgery revealed a recurrent epidermoid cyst containing a viscid, dark-green fluid without any cholesterol crystal or clots. Chemical analyses of the cyst content disclosed protein and lipid concentrations 25.6 g/dl and 1,275 mg/dl, respectively. Ion chromatography revealed only a trace of metal ions. Thin layer chromatography of the lipids showed high phospholipids and low triglyceride, indicating that the high density in this case was not caused by an intratumoral hemorrhage but by desquamation of the squamous epithelium with accumulation of sloughed debris. Two cases of high-density epidermoids subjected to protein analysis were found in the literature. From these data including the authors' it was shown that CT density correlated well with the protein concentration. (author)

Pineal epidermoid coinciding with pineocytoma.  

Science.gov (United States)

Tumours of the pineal region are uncommon. We report on a 62-year-old male presenting with Parinaud's syndrome and aqueduct stenosis caused by a cystic tumour in the pineal region. During surgery, adjacent to the cystic tumour, a second smaller tumour was identified, which was clearly separate from the first tumour and from the pineal gland. Histological examination disclosed the cystic tumour as an epidermoid cyst, whereas the second tumour demonstrated histological and immunohistochemical features of a pineocytoma. The unique finding of two different types of tumours in the pineal region is evaluated with regard to the histogenesis of epidermoid cysts and pineocytomas. PMID:14505106

Recurrent meningitis due to epidermoid  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Aseptic meningitis is characterized by noninfective serous inflammation of the meninges. It can occur in a recurrent fashion when associated with dermoid and epidermoid cysts due to rupture of cyst contents into subarachnoid space resulting in aseptic chemical meningitis. Bacterial meningitis in association with these tumors is commonly related to a coexisting dermal sinus tract and the most common organism is Staphylococcus aureus.

Testicular tumors  

International Nuclear Information System (INIS)

Although the testicular cancer considers only one percent of all the tumors in males, it is the most common malignancy of males between 15 and 34 years old. Cryptorchidism is the most significant risk factor for testicular cancer, increasing the risk up to eleven times. A testicular mass without pain is the classic presentation for the testicular cancer, although a number of patients presents with diffuse pain or swelling. Ultrasonography can be profitable in confirming the presence of a scrotal mass inside the testicle. The intra testicular masses are considered bad until having proven otherwise. Radical orchiectomy is the treatment for the primary tumor. The staging of the illness is based on the histology of the tumor markers of serum, presence of lymph nodes or metastasis illness. Depending on the stage of the illness, the additional treatment can include observation, radiotherapy, chemotherapy or surgery. The rates survival in patient with the testicular cancer have improved dramatically in the last 20 years and now they exceed 90 percent of total. (The author)

Se realizó el análisis retrospectivo de las histo [...] rias clínicas de 5 pacientes portadores de quiste aracnoideo, en los que la forma de presentación consistió en higroma subdural e hipertensión endocraneana. Resultados. El rango de edad fue entre 3 y 15 años (promedio: 7 años). La relación M/F fue 3/2. En 3 casos los síntomas se presentaron después de un traumatismo encefalocraneal leve y en los 2 restantes fue espontáneo. Todos se manifestaron con síntomas de hipertensión endocraneana y edema de papila bilateral, en 2 de ellos se constató paresia del VI par izquierdo. A todos se les realizó TAC y en 2 casos IRM. En los 5 pacientes se constató un higroma subdural con efecto de masa y quiste aracnoideo de fosa media. Se realizó tratamiento quirúrgico de urgencia en los 5 casos. Todos los pacientes evolucionaron favorablemente con desaparición del higroma subdural. Actualmente se encuentran asintomáticos con un examen neurológico y fondo de ojo normal. Conclusión. Si bien el higroma subdural con hipertensión endocraneana es una complicación poco usual, debe ser tenida en cuenta como una de las formas de presentación clínica de los quistes aracnoideos, la cual requiere inmediata resolución quirúrgica.

Methods: The clinical records of 5 patients with arachnoid cysts presenting as a subdural hygroma w [...] ith increased intracranial pressure were analyzed retrospectively. Results: The ages of the patients ranged between 3 and 15 years (mean: 7 years). M/F ratio was 3/2. Onset of symptoms was postraumatic in 3 and spontaneous in 2. All patients presented symptoms of increased intracranial pressure and bilateral papilledema, and in 2 out of 5 paresis of the VI cranial nerve was found. All children underwent CAT scan and MRI was performedin 2. In all patients, subdural hygroma with mass effect and arachnoid cyst of the middle fossa was found. Emergency surgery was carried out in all cases. All patients evolved favorably with complete disappearance of the subdural hygroma. They are currently asymptomatic with normal neurological examination and fundoscopy. Conclusion: Even though subdural hygroma with increased intracranial pressure is an unusual complication, it should be known as one of the clinical presentations of arachnoid cysts, which required immediate surgical intervention.

Recurrent intramedullary epidermoid cyst of conus medullaris.  

LENUS (Irish Health Repository)

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.

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).

[Epidermoid carcinoma of the thyroid].  

Science.gov (United States)

About thyroid neoplasms the epidermoidal carcinoma represents an ingrown minority (0.3-0.74%). Several etiopathological hypotheses are considered and this testifies the notable uncertainty that still winds the origin of the neoplasm. In the actual case, the more accredited hypothesis foresees the origin of the neoplasm from a histopathological of Hashimotos' tyhroiditis. The objectivity of the case in examination constitutes the clinical picture of reference of the malignant neoplasms of the thyroid: oligosintomatic low cervical mass of increased consistence, adherent to the imminent pianos strictly following laryngeal movements, dysfagia and dysfonia. Additionally they were present pulmonary and right cervical lymphonodal metastases. After an adjuvant treatment with Paraplatin and 5-FU, to some months from the intervention of total thyroidectomy, local relapse in form of a festered mass is highlighted in sovrajugular region with result in cutaneous-esophagustracheal fistula. The diagnosis of certainty of the neoplasm, despite the rarity, it doesn't constitute a problem, albeit the percents of survival, anyway substantially more favorable respect to anaplastic neoplasms, concerning to as numerical as chronological aspects, result to be hardly discouraging.

Acquired Epidermoid Cysts of the Cauda Equina  

Science.gov (United States)

Intradural extramedullary epidermoid (EC) cysts are uncommon (0,2–1%). Acquired tumors appear more frequently as a late complication of lumbar punctures (40%). The authors present three cases of epidermoid cysts of the cauda equina which were surgically treated in their department during the past five years. All three had suffered lumbar punctures for rachianesthesia 6–9 years prior to their presentation. The patients' ages ranged between 19 and 31. Surgical treatment was deemed necessary because of the space–occupying nature of this slow–growing lesion, and this indication was supported by the MRI findings. Two–level laminectomy and microsurgical total tumor ablation were performed in all three cases. There were no postoperative complications.

Epidermoid Carcinoma of the Anal Canal  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Anal cancers are rare tumors with only an expected 4000 new diagnoses in 2005. The majority of these are epidermoid or squamous cell cancers. Despite the rarity of this disease, great advances have been made in its understanding and treatment. The human papillomavirus (HPV), immunosuppression for solid organ transplantation, the human immunodeficiency virus (HIV), and sexual practices are changing the demographics of the disease from elderly women to young men who have sex with men and young ...

Orbital dermoid and epidermoid cysts: Case study  

Directory of Open Access Journals (Sweden)

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

Testicular Germ Cell Cancer  

Science.gov (United States)

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.

Quiste óseo aneurismático / Aneurysmal bone cyst  

Scientific Electronic Library Online (English)

Full Text Available SciELO Cuba | Language: Spanish Abstract in spanish 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.

Los quistes dentígeros suelen ser, en la mayor parte de los casos, un hallazgo casual; por lo general se descubren al investigar la no erupción de un diente permanente. Ocupan el segundo lugar en frecuencia de aparición en los maxilares después del quiste radicular. Cuando el seno maxilar es invadido por estos quistes los síntomas usualmente aparecen tardíos en el proceso. Estos pueden incluir dolor facial, parestesia como consecuencia de la presión sobre un nervio, dolor de cabeza, tr...

Materia [...] l y Métodos: Estudios previos donde se observaban quistes pequeños subpleurales se seleccionaron 39 TCAR de 33 pacientes con colagenopatías confirmadas y 6 con enfermedad intersticial idiopática y se los reexaminó entre octubre de 2008 y junio de 2009. El equipo utilizado fue un tomógrafo computado multislice Philips Brillance de 16 canales. Los cortes fueron de 1 mm de espesor, de ápices a bases. La evaluación se realizó con la técnica habitual, adicionando la MinIP en cortes axiales, sagitales y coronales, con rotación del parénquima y especial atención en las áreas que presentaban quistes. Se efectuaron además cortes en espiración. Resultados: De 20 TCAR que mostraban quistes subpleurales con la técnica habitual, 14 (70%) correspondieron a bronquioloectasias. En 12 casos, todas las imágenes eran bronquioloectasias; en 2 casos, ellas predominaban, observándose también quistes aislados. Se pudo definir la existencia de quistes verdaderos en 6 casos (30%), todos con Neumonitis Intersticial Usual (NIU). Valor predictivo positivo (VPP) de la TCAR para detección de quistes: 30% (IC95% 0.13-0.54). Conclusiones: Los trabajos publicados sobre enfermedades intersticiales se basan en la evaluación con cortes axiales de TCAR y la demostración de quistes es de suma importancia para diferenciar NIU de la Neumonía Intersticial No Específica (NINE). En este estudio, se evidencia que la utilización de MinIP con rotación del parénquima redefine 70% de los quistes como bronquioloectasias. Dado el rol cardinal de la TCAR en la evaluación de las intersticiopatías, es importante un estudio prospectivo de seguimiento con mayor número de casos que confirme si son los quistes reales y no los redefinidos como bronquioloectasias los que caracterizan a la NIU. Abstract in english Objective: To demonstrate that axial sections on high-resolution computed tomography (HRCT) are insufficient for an accurate examination of diffuse interstitial lung diseases. To further show that minimum intensity projection (MinIP) increases diagnosis specificity. Material and methods: Preliminary [...] studies reporting small subpleural cysts were used to select 39 HRCT from 33 patients with confirmed collagen diseases and 6 patients with idiopathic interstitial disease. Patients were reexamined between october 2008 and june 2009. A 16-channel Philips Brillance multislice CT scanner was used. Sections were 1 mm thick de apices a bases. Patients were examined using the common technique, including the MinIP for axial, sagittal and coronal sections, with parenchymal rotation. Cystic areas were carefully examined. Spiral sections were also performed. Results: Of 20 HRCT depicting subpleural cysts with the conventional technique, 14 (70%) were bronchiolectases. In 12 cases, images were all bronchiolectases; in the other 2, a prevalence of bronchiolectases and isolated cysts were seen. Real cysts could be confirmed in 6 cases (30%), all of which presented usual interstitial pneumonitis (UIP). The HRCT positive predictive value (PPV) for cyst detection was 30% (95% CI 0.13-0.54). Conclusions: Interstitial diseases reports focus on performing axial sections on HRCT, and cyst detection is pivotal to differentiate UIP from NINE. This study reveals that the use of MinIP with parenchymal rotation redefines 70% of cysts as bronchiolectases. Given the key role of HRCT in the examination of interstitial diseases, it is important to carry out a prospective follow-up study with a larger number of cases, in order to confirm whether the UIP is characterized by real cysts or by cysts redefined as bronchiolectases.

CT scan findings of malignant epidermoid cyst  

International Nuclear Information System (INIS)

The authors report a case of malignant epidermoid cyst (MEC) and discuss the characteristic findings on computed tomography (CT) scan, the differential diagnosis and the difference from the atypical findings of benign epidermoid cyst (BEC) with a review of the literature. A 60-year-old female complained of right oculomotor palsy and syncopal attacks. Plain CT scan revealed an irregularly low-density lesion with a ring-like and nodular high-density area mainly in the suprasellar cistern and midbrain, and another iso- to a slightly high-density area in the medial aspect of the right temporal lobe. On enhanced CT scan, a faint and inhomogeneous enhancement was observed in the lesion of the right temporal lobe. Surgical treatment was performed, and pathological examination of the specimen from the medial aspect of the right temporal lobe showed malignant change in the BEC. As a common and characteristic feature of CT scan findings of the present and the five previously reported cases, MEC shows homogeneous or inhomogeneous enhancement in the iso- to a slightly high-density lesion or the low-density lesion found in a typical BEC.

Isodense epidermoid cyst in the pineal region  

International Nuclear Information System (INIS)

A 69-year-old male was admitted complaining of gait disturbances and diplopia, 2.5 years after an episode of serous meningitis. Neurological examination on admission disclosed Parinaud's sign, unsteady gait and dysdiadochokinesis on the left side. A striking finding on the computerized tomography (CT) was the left to right shift of the posterior portion of the third ventricle without visualization of the quadrigeminal and ambient cisterns, which were almost completely occupied by an isodense mass accompanied by high dense flecks and a low dense part. Enhanced CT showed positive enhancement in the vicinity of the pineal calcification. By the suboccipital supracerebellar approach, an encapsulated mass containing brownish yellow fluid was subtotally removed and a histological examination of it revealed epidermoid tissue and hemosiderin deposits in the solid portion. Few reports of isodense epidermoid cysts have so far been found in the literature giving a full explanation for this unusual CT attenuation value. Based on the clinical course and histology of this case, the pathogenesis of the unusual density is discussed along the following lines: The mixture of the low dense factor due to cholesterin and the high dense factor due to prior bleeding is believed to result in the isodense attenuation value in the liquid portion. Also, in the solid part, a microscopically mixed texture of deposited hemosiderin and cholesterin clefts in the inflammatory granulomatous tissue could explain its density on the CT scan. (author)

En diferentes series de pacientes operados por quistes tiroglosos su incidencia fue del 0.7 al 1.07%. Luego de la extirpación del quiste por el procedimiento de Sistrunk, no hay consenso sobre la indicación de tiro [...] idectomía total, radioablación y/o terapéutica supresiva con levotiroxina. El objetivo del Departamento de tiroides de SAEM, fue evaluar: formas de presentación, evolución clínica, métodos diagnósticos de utilidad y tratamiento para consensuar futuras conductas. Material y Métodos: Estudio multicéntrico, retrospectivo en 22 pacientes entre 10 a 69 años, 15 mujeres y 7 varones. Resultados: El tamaño de los quistes osciló entre 1 y 8 cm (Mediana= 3.0 cm, ? ± DS= 3.7 ± 2.2 cm). La mitad de los pacientes presentó crecimiento del quiste en los 6 meses previos a la cirugía. La punción resultó sospechosa en 2/5 quistes y positiva en uno. La ecografía tiroidea evidenció nódulos en 4/13 casos (30%). Se realizó tiroidectomía en 17/22 pacientes (total: 15 y subtotal: 2). La histología del CaQT demostró carcinoma papilar en 21 y carcinoma folicular en uno. Hubo coexistencia de cáncer intratiroideo en el 23.5% de los casos, ninguno multicéntrico. Dos pacientes presentaron metástasis ganglionares y otro tuvo compromiso muscular (ninguno de ellos coexistió con cáncer intratiroideo). Se radioablacionó a 13 pacientes. En 9/11 pacientes la tiroglobulina permaneció indetectable durante el seguimiento (1 a 14 años). Conclusiones: 1) Realizar ecografía de cuello y punción ecoguiada a todo paciente con quiste tirogloso. 2) En caso de CaQT combinar simultáneamente tiroidectomía total y procedimiento de Sistrunk. 3) Evaluar radioablación complementaria y tratamiento supresivo con levotiroxina en cada caso. 4) Efectuar el seguimiento tal como en los carcinomas ortotópicos. Abstract in english Differentiated thyroid carcinoma (DTC) in thyroglosal duct cyst (TGDC) is rare, ranging from 0.7 to 1.07% in different series. After the surgery of choice (Sistrunk procedure) the other alternative treatments such as thyroidectomy (Tx), radioiodine and L-T4 therapy are controversial. OBJECTIVE: to e [...] valuate several and controversial aspects in the largest series of DTC in TGDC reported in the literature. Subjects and methods: retrospective multicentric study: n= 22, aged 10-69 yrs. (15 females and 7 men) who underwent the Sistrunk procedure for TGDC. Results: none of the TGDC was less than 1 cm (median 3.0 cm, ?±SD= 3.7 ± 2.2cm). In half of them there was an increased cystic size in the last 6 months before surgery. Cyst FNA was suspicious in 2/5 and positive in one, whereas the histological diagnosis of the operated TGCD was papillary cancer in 21 and 1 follicular carcinoma. Thyroid ultrasound (US) (n=13) showed nodules in 30% of the cases. Tx was performed in 17/22 (total: 15, subtotal: 2). Thyroid DTC coexisted in 4/17 (23.5%), and was unilateral in all of them. Lymph node metastases were present in 2 adults and muscle involvement was found in the 10-year old girl. None of these 3 patients had overt thyroid lesions. 131-I therapy was performed in 10 patients. In 9 out of 11 subjects Tg remained undetectable during follow-up (1-14yrs.). Persistent high Tg was present in one case without thyroid DTC. Conclusions: 1) Ultrasonography and FNAB should be performed to every patient with thyroglossal duct cyst 2) In case of TGDC, total Tx and Sistrunk's procedure should be simultaneously combined 3) 131-I therapy and L-T4 suppressive treatment should be evaluated in every case 4) Follow-up as in the DTC.

Giant Pelvic Retroperitoneal Epidermoid Cyst: A Rare Case Report  

Science.gov (United States)

Epidermoid cyst is a frequent benign cutaneous tumor. The pelvic localization does not occur very often. The literature that taps into such cases is very limited in scope. Here is a report of a 27-year-old woman with a giant pelvic retroperitoneal epidermoid cyst. The use of ultrasound exploration and computed tomography has indicated ovarian origins. The surgery also revealed a retroperitoneal epidermoid cyst, uterus and ovaries were all intact. The evacuation of a cyst was found to contain lamellas of keratin. Histology permitted us to confirm the diagnosis. The patient was faring well after two years of followup.

It is a variety of the metaplastic carcinoma constituted by pavement keratinizing cells with an inconstant presence of fusocellular sarcomatoid elements, that reach great volume and frequently present as cystic tumours that may be confused with a breast abscess. This is the case of a 41 year-old white female from Cienfuegos municipality, Cuba, who presented to the provincial Mastology consultation because of a two month follow up of a 5 cm tumor in the right outer upper quadrant of her breast. Surgical removal of the tumor was performed and the result of the biopsy revealed a little differentiated epidermoid carcinoma. At present the patient has no metastasis and receives treatment at the outpatient. Its unusual presentation has led this case to be published. El carcinoma epidermoide primitivo es considerado el tumor más raro de la mama, con una incidencia que representa solo del 0,04 al 0,075 % de todos los tumores malignos de mama. Es una variedad de carcinoma metaplásico constituido por células pavimentosas queratinizantes, con presencia inconstante de elementos fusocelulares sarcomatoides, estos alcanzan grandes volúmenes y se presentan frecuentemente como tumoraciones quísticas que pueden confundirse con un absceso mamario. El caso que se presenta es una paciente femenina de 41 años de edad, de color de piel blanca, residente en el municipio de Cienfuegos que acudió a la consulta de Mastología de la provincia por presentar una tumoración de 5 cms. en el cuadrante superior externo de la mama derecha, de dos meses de evolución. Se realizó exèresis de la tumoración y se recibió informe de la biopsia con el resultado de carcinoma epidermoide poco diferenciado. Actualmente la paciente es seguida por consulta y está libre de metástasis. Por lo inusual del caso se decide su publicación.

Intrarenal epidermoid cyst presented as an enlarged multicystic kidney  

Directory of Open Access Journals (Sweden)

Full Text Available This report describes a case of large multiple and multilocular epidermoid cysts affecting the left kidney of a 67 old male. The condition was accidentally discovered during the ultrasonography for left loin pain and revealed enlarged left kidney with picture suggestive of hydronephrosis. Grossly, the kidney was distorted cysts that were filled with a cheesy material. The histologic picture of an end stage kidney disease was apparent in the compressed renal parenchyma by these cysts that were identical to an epidermoid cyst elsewhere. In conclusion, although rare, epidermoid cyst of the kidney could cause serious kidney damage leading to an end stage kidney disease. Epidermoid cyst of the kidney could be multiple producing a picture similar to hydronephrosis andbroadening the differential diagnosis of multicystic disease of the kidney.

Intraspinal epidermoid cyst: diffusion-weighted MRI  

International Nuclear Information System (INIS)

We report a 7-year-old boy who presented with two-month history of worsening low back and right leg pain. Conventional MR images demonstrated a poorly outlined intradural mass recognized by the displacement of the conus medullaris and the nerve roots of the cauda equina at the L2-3 level. The signal intensity of the lesion was similar to CSF. There was no contrast enhancement of the lesion. Diffusion-weighted images and ADC values revealed restricted diffusion within the mass. Myelography confirmed the mass as an intradural filling defect with myelographic block at the L2-3 level. The patient underwent total surgical excision of the mass. Pathologic examination revealed the diagnosis of epidermoid cyst. (orig.)

[Malignant degeneration in a parapontine epidermoid (author's transl)].  

Science.gov (United States)

A case of malignant degeneration in a right parapontine epidermoid cyst giving rise to leptomeningeal carcinomatosis in a 57 year old woman is presented. The malignant tissue had infiltrated the right cerebellar hemisphere and produced a symptomatic trigeminal neuralgia, a change in the psychological state of the patient, and an acute conus and cauda syndrome following metastasis implantation. Only eight unequivocal previous reports of malignant transformation of intracranial epidermoid cyst have been reported in the literature with metastases in four. PMID:910653

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish La hidatidosis es una enfermedad endémica en el área mediterránea, pero su presentación como shock anafiláctico sólo acontece en un escaso porcentaje, oscilando entre un 1 y un 7,5%. Esta manifestación se produce al romperse el quiste hidatídico, liberando al exterior su contenido. El diagnóstico et [...] iológico es fácil cuando el shock se presenta durante la manipulación quirúrgica del quiste hidatídico, pero la dificultad surge cuando se produce por la rotura espontánea del mismo. Se debe sospechar en pacientes sanos que vivan en zonas endémicas y que presenten súbitamente un cuadro de colapso vascular. No suele haber antecedentes de quistes hidatídicos en estos pacientes, aunque la historia clínica suele poner de manifiesto la existencia de antecedentes compatibles con procesos alérgicos no filiados. Abstract in english Hidatidosis is an endemic disease in the mediterranean area, but his presentation as anaphylactic shock only takes place in a rare percentage, oscillating between 1 and 7.5%. This manifestation occurs when the hydatid cyst breaks, liberating his content to the outside. The etiologic diagnosis is eas [...] y when the shock takes place during the surgical manipulation of the hydatid cyst, but the difficulty comes up when it occurs because of the spontaneus rupture of it. It must be suspected in healthy patients living in endemic areas and who show a sudden pattern of vascular collapse. These patients rarely have a previous record of hydatic cysts, but their clinical history usually shows the existence of a previous record of non-filiated allergic processes.

Abordaje endoscópico de los quistes gliales pineales sintomaticos  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish Objetivo. Los quistes gliales pineales (QGP) son infrecuentes. El manejo quirúrgico de estos quistes no está consensuado. En la literatura se recogen 18 casos tratados por vía endoscópica. El objetivo de este trabajo es contribuir con nuestra experiencia en el tratamiento endoscópico de los QGP. 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.

The purpose of this study is to contribute with our experience to the endoscopic treatment of the GPC. Mat [...] erials and Methods. 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.

Epidermoid Cyst of the Neck in an Elderly Patient  

Directory of Open Access Journals (Sweden)

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.

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

Energy Technology Data Exchange (ETDEWEB)

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.

Spinal epidermoid cyst with sudden onset of paraplegia  

Directory of Open Access Journals (Sweden)

Full Text Available Spinal epidermoid cysts, whether congenital or iatrogenic, are relatively uncommon in the spinal cord. When they occur, the typical location is in the subdural, extramedullary space of the lumbo-sacral region. We describe an unusual presentation in a 3-year-old male child which mimicked astrocytoma clinicoradiologically. The child developed sudden onset of inability in walking and weakness of both lower limbs after a fall. There was a dramatic reversal of symptoms after surgery. Histopathology revealed an epidermoid cyst of the spine. On the first follow-up visit at 3 months, the child was asymptomatic.

[Clitoral epidermoid cyst causing clitoromegaly. A rare case report].  

Science.gov (United States)

Clitoromegaly is uncommon. It is mostly congenital, hormonal or tumoral. Epidermoid cyst is rare. It can be the consequence of trauma, but in some situations the cyst can be non-traumatic. We report the case of a 53-year-old woman who presented a misdiagnosis of clitoromegaly due to hormonal condition. Surgical exploration has highlighted an epidermoid cyst. This observation underlines the importance to evoke a cystic origin for clitoral hypertrophy and encourages us to propose imaging (ultrasound, MRI) in case of etiological doubt. The preoperative diagnosis must be made to preserve vascularization and innervation of the clitoris. PMID:24035179

FDG uptake in splenic epidermoid cyst with hemorrhage.  

Science.gov (United States)

Splenic epidermoid cyst is a rare entity and rarely becomes complicated by hemorrhage. We present a case of splenic epidermoid cyst with old hemorrhage showing strong FDG uptake in the cyst wall. Histopathology revealed granulation tissue with abundant inflammatory cells, including many hemosiderin-laden macrophages, in the inner layer of the cyst wall. The abundant inflammatory cells in the granulation tissue may contribute to the strong FDG uptake of the cyst wall. This case highlights that a benign lesion with hemorrhage should be included in the differential diagnosis of abnormal splenic FDG uptake along with tumor and inflammatory processes. PMID:23455524

Current management strategies for testicular microlithiasis.  

Science.gov (United States)

The association of testicular microlithiasis with testicular tumor and the management of incidentally detected testicular microlithiasis have generated a great deal of interest. We review the current literature on testicular microlithiasis with regard to its association with testicular tumor. This association seems complex. The available data suggest that men with incidental findings of testicular microlithiasis but who have otherwise normal testes are at low risk of developing testicular cancer. The only follow-up recommended is regular testicular self-examination. Testicular microlithiasis is, however, associated with a high risk of developing testicular malignancy in men with subfertility, history of contralateral testicular tumor or history of cryptorchidism. Regular testicular self-examination is recommended for follow-up of high-risk patients, but the role of surveillance with serial ultrasonography and measurement of tumor markers is still not clear.

Evaluation of radionuclide testicular scan  

International Nuclear Information System (INIS)

There has been no adequate diagnostic method for the diagnosis of intrascrotal lesions until recent days. But after the development of radionuclide testicular scan, early and relatively accurate diagnosis of the testicular lesions are possible. So the authors analyzed the 32 cases of patients who were examined by testicular scan and confirmed by follow up study or operation, and the results are as follows: 1. These 32 cases consists of 13 cases of epididymitis, 7 cases of testicular torsion, 4 of cryptorchism, 2 of testicular tumor and etc. The over all diagnostic accuracy is about 69%. 2. In epididymitis, the diagnostic accuracy is 85% (11/13) and the findings of scan are increased perfusion in radionuclide angiogram and hot activity noted mainly in peripheral portion of the testicle in static image. 3. In case of testicular torsion, diagnostic accuracy is 86%(6/7). Acute torsion shows normal perfusion in angiogram and round cold area in static image. But in missed torsion, perfusion is increased and round cold area with surrounding hyperemia is noted in static image. Radionuclide testicular scan seems to be noninvasive, inexpensive, easily available and simple to performed with low gonadal radiation dose. So it can be very useful as the first study in patients with acute testicular symptoms

Testicular Teratoma in an Infant: Case Report  

International Nuclear Information System (INIS)

Testicular masses, and especially testicular teratoma, are uncommon entities in children. We present the case of a 45-day-old male patient with a left scrotal mass. Doppler ultrasound reported left testicular growth due to the presence of a mass with heterogeneous echogenicity. The patient underwent radical orchidectomy and the pathological analysis revealed a testicular teratoma composed of the three germinal layers.

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 10"6/ml, and 19 (61.3 %) showed oligospermia or azoospermia with sperm counts of less than 10 x 10"6/ml. 3. Of 20 patients who underwent retroperitoneal lymphnode dissection, 15 developed ejaculation deficiency. Four other patients also developed ejaculation deficiency but recovered, and three of them rendered their wives pregnant. 4. Of 23 patients given radiotherapy, nine produced children both before and after treatment, nine produced children before treatment but showed sterility after treatment, and five showed sterility both before and after treatment. 5. Examination of semen was performed in 17 patients given radiotherapy and in five given chemotherapy. Many patients developed oligospermia or azoospermia after the treatments, but revealed a tendency to recover with time. Based on the results mentioned above, it is inferred that the ability to produce sperm in patients with testicular tumor after treatment decreases but the decrease tends to recover to normal with time.

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. 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

Testicular carcinoid generally presents either with a palpable (painful or painless) or rarely a nonpalpable mass (when it is diagnosed incidentally on scrotal imaging) of the involved testis. An ipsilateral testicular carcinoid presenting exclusively with contralateral testicular symptoms has never been described in the literature to date. We report a case of nonpalpable left testicular carcinoid diagnosed incidentally on a sonogram done for right testicular pain and swelling, with conspicuo...

Surgical treatment of intradiploic epidermoid cyst treated as depression  

Directory of Open Access Journals (Sweden)

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 tumors of the temporal lobe as epileptogenic foci.  

Science.gov (United States)

Intracerebral epidermoid tumors of the temporal lobe are exceedingly rare. The vast majority of these slow-growing tumors remain clinically silent while only a select few are associated with overt symptomatology. We report two patients with epidermoid tumors whose unique location in the temporal lobe resulted in secondarily generalized seizures. Our first patient, a 19-year-old female, presented with a secondarily generalized tonic-clonic seizure and MRI revealed a superior temporal lobe lesion that was subsequently treated with an awake craniotomy and gross total resection. Our second patient was a 71-year-old male with a recent seizure history and known left temporal lobe lesion. The patient underwent craniotomy for gross total resection of the mass. In these two patients, we found that MRI proved diagnostic and surgical resection was curative. Our clinical experience and review of the literature indicate that gross total resection of these lesions confers control of localization-related epilepsy. PMID:21802304

[Seminoma necrosis by testicular torsion].  

Science.gov (United States)

The coincidence of a classical scrotal testicular torsion with a scrotal tumor is a rare event. In the case described here the classical histological characteristics of a seminoma were present in addition to clear signs of testicular torsion with fibrin-containing thrombi in the intratesticular capillaries, so that the ischemia time predicted by the pathologists correlated well with the clinical data of 7.5 h for the testicular torsion estimated at the time of the intervention. The intraoperative diagnosis made by the surgeon allowed a rapid response with only a semi-castration, excision of the wound edges and a highest possible amputation of the funiculus. PMID:19859689

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. PMID:17334483

Quiste mesentérico: experiencia en 4 casos Mesenteric cyst: experience in 4 cases  

Directory of Open Access Journals (Sweden)

Full Text Available El quiste mesentérico es una enfermedad poco frecuente, cuya importancia ha sido menospreciada en demasiadas ocasiones en la literatura médica. La baja incidencia de la enfermedad y la creencia errónea de que se trata de un proceso benigno y asintomático han contribuido al escaso interés por su conocimiento. Se realizó un estudio retrospectivo con revisión de los pacientes ingresados en el Servicio de Cirugía General y Digestiva del Hospital General de Castellón entre enero de 1990 y noviembre de 2005. Se diagnosticaron 4 quistes mesentéricos de los 34 355 ingresos en nuestro servicio. La mitad eran mujeres y la media de edad fue de 25 años. Tres casos presentaron síntomas y sólo uno fue un hallazgo casual. La manifestación clínica más frecuente fue el dolor abdominal leve y difuso. Uno de los pacientes se complicó con una perforación espontánea del quiste y peritonitis. El tratamiento fue la exéresis quirúrgica en todos los casos. Las vías de abordaje fueron: 3 laparotomías y 1 laparoscopia. Únicamente un caso requirió resección intestinal por déficit en la vascularización. No hubo ninguna recidiva tras la cirugía. A pesar de la baja frecuencia de esta enfermedad, su conocimiento es necesario ya que se pueden presentar síntomas cuando el quiste ha crecido, así como complicaciones graves (hemorragia, perforación, obstrucción intestinal, malignización, etc., que se pueden prevenir con la intervención quirúrgica, incluso en los casos asintomáticos

Opciones terapéuticas en quistes odontogénicos: Revisión Therapeutic options in odontogenic cyst: Review  

Directory of Open Access Journals (Sweden)

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 maxilares 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.The maxillary bones constitute the base of a big variety of cyst and tumours that can be difficult to diagnose. Among all the tumor processes that can occur in the maxillofacial area, cysts are of the utmost importance due to their frequency. Jaw cysts have different origins and clinical behavior. After 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.

Abstract in english The maxillary bones constitute the base of a big variety of cyst and tumours that can be difficult to diagnose. Among all the tumor processes that can occur in the maxillofacial area, cysts are of the utmost importance due to their frequency. Jaw cysts have different origins and clinical behavior. 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.

Studies of testicular function after treatment for testicular tumor, 2  

International Nuclear Information System (INIS)

It is important to preserve the testicular function of patients with testicular tumor after treatment. Testicular function after radiotherapy was endocrinologically investigated in the present study. 1. The levels of LH, FSH and testosterone in the blood were sequentially determined in patients with testicular tumor before, during and after radiotherapy. The blood levels of LH and FSH were high after therapy in the majority of the cases, but the levels decrease concomitantly with time. Blood levels of testosterone remained within the normal range. 2. The Gn-RH stimulation test after radiotherapy revealed an abnormally high response and a delayed normalization of the LH level within three years after therapy. However, these changes showed a tendancy to normalize in the patients after therapy for three years or longer. 3. The hCG stimulation test was performed after radiotherapy. The reaction rate of hCG was low in patients within three years on therapy, whereas it tended to return to normal pattern after three or more years on therapy. The results lead the conclusion as follows. 1. Spermatogenesis was damaged in the majority of testicular tumor after radiotherapy. However, it was recovered to a normal spermatogenesis after cessation of the therapy. 2. From the high basal level of serum LH and the response to Gn-RH and hCG stimulation tests after radiotherapy, it is presumed that the reserve function of Leydig cell was impaired by radiotherapy, although it returns to normal status after three years on the therapy.

Radiotherapy of testicular tumours  

Energy Technology Data Exchange (ETDEWEB)

In the first part of the paper, the general pathological, diagnostical and therapeutical measures against seminomas and teratomas are dealt with. In the second part, the results obtained by the radiotherapeutical division of the University Clinics of Freiburg 1964-1977 in the treatment of seminomas and teratomas are described. The average age of the 59 seminoma patients was 36 years, the average age of the 28 teratoma patients was 26. The 5-years-total survival rate of the seminoma patients was 80.8%, for teratoma patients it was 30.5%. In the individual phases, of all seminoma patients in stage I, 93.1% were still alive after 5 years, in stage II 95.9%, in stage III 12.5%. The 5-years survival rate of the teratoma patients in stage I was around 100%, in stage II around 36.8% and in stage III around 20.5%. In the discussion, the problems of the histological and pathological classification for testicular tumours are talked about and the treatment methods used at the Freiburg university clinics are described. The results obtained in the Freiburg university clinics are compared with those of other authors.

Clitoral epidermoid cyst presenting as pseudoclitoromegaly of pregnancy.  

Science.gov (United States)

Objective?Acquired clitoromegaly is rare and may result from hormonal and nonhormonal causes, and evaluation of the pregnant patient with clitoromegaly invokes a specific set of differential diagnoses. Methods?Case report. Results?We describe the case of a young woman with pregnancy-associated clitoral enlargement whose hormonal evaluation proved negative. Further investigation concluded that an epidermoid cyst was the culprit of her pseudoclitoromegaly. The patient underwent successful surgical resection and has had no recurrence at her subsequent pregnancy. Conclusion?We review the differential diagnosis of clitoromegaly, including hormonal and nonhormonal causes, with focus on the evaluation of pregnancy-associated clitoromegaly. PMID:23943712

Isodense epidermoid cyst in the pineal region. Case report  

Energy Technology Data Exchange (ETDEWEB)

A 69-year-old male was admitted complaining of gait disturbances and diplopia, 2.5 years after an episode of serous meningitis. Neurological examination on admission disclosed Parinaud's sign, unsteady gait and dysdiadochokinesis on the left side. A striking finding on the computerized tomography (CT) was the left to right shift of the posterior portion of the third ventricle without visualization of the quadrigeminal and ambient cisterns, which were almost completely occupied by an isodense mass accompanied by high dense flecks and a low dense part. Enhanced CT showed positive enhancement in the vicinity of the pineal calcification. By the suboccipital supracerebellar approach, an encapsulated mass containing brownish yellow fluid was subtotally removed and a histological examination of it revealed epidermoid tissue and hemosiderin deposits in the solid portion. Few reports of isodense epidermoid cysts have so far been found in the literature giving a full explanation for this unusual CT attenuation value. Based on the clinical course and histology of this case, the pathogenesis of the unusual density is discussed along the following lines: The mixture of the low dense factor due to cholesterin and the high dense factor due to prior bleeding is believed to result in the isodense attenuation value in the liquid portion. Also, in the solid part, a microscopically mixed texture of deposited hemosiderin and cholesterin clefts in the inflammatory granulomatous tissue could explain its density on the CT scan.

Full Text Available SciELO Brazil | Language: English Abstract in english OBJECTIVE: To prospectively determine the prevalence of testicular microlithiasis in symptomatic patients who were referred for scrotal ultrasound examination and to evaluate the possible association of testicular microlithiasis with testicular cancer and other conditions such as cryptorchidism or h [...] istory of ascending testis. MATERIALS AND METHODS: 391 men who were referred to our institutions between July 2002 and May 2005 for any type of symptoms from the testicles, underwent physical and scrotal ultrasound examination. The presence of testicular microlithiasis, the number of lesions and the involvement of both testicles in relation to the symptoms as well as the coexistence of other lesions were studied. RESULTS: Eighteen (4.6%) of 391 men enrolled into the study had testicular microlithiasis. Two out of the eighteen patients (11%) had concomitant testicular cancer, which was confirmed by pathological evaluation of the orchidectomy specimen. One of the patients with testicular microlithiasis presented a rising in biochemical tumor markers (LDH, and HCG) and underwent orchidectomy one year later. Five of the remaining 373 (1.3%) patients without microlithiasis were diagnosed with testicular cancer. Thirty six men reported having a history of ascending testis, but none of them was found with testicular cancer. Two cases of testicular torsion in a cryptorchid position had testicular microlithiasis, but the orchidectomy specimen (after surgery) was negative for testicular cancer. The correlation between testicular cancer and testicular microlithiasis found in our study was statistically significant (p

Diffusion-weighted MRI postoperative assessment of an epidermoid tumour in the cerebellopontine angle  

International Nuclear Information System (INIS)

Cerebellopontine angle epidermoid tumour generally has a typical appearance with conventional MRI sequences. The lesion is irregular in shape and gives slightly higher signal than cerebrospinal fluid on T1- and T2-weighted images, with a characteristic marbled inner pattern on T1-weighted images. Diffusion-weighted imaging (DWI) can be useful for the diagnosis of an atypical epidermoid tumour. Our case report illustrates the usefulness of DWI for postoperative assessment of residual foci of tumour. The specific appearance of an epidermoid tumour is illustrated, with emphasis on apparent diffusion coefficient (ADC) measurements. (orig.)

DWI findings in a iatrogenic lumbar epidermoid cyst. A case report.  

Science.gov (United States)

Epidermoid cysts comprise less than 1% of intraspinal tumors. They can be congenital, frequently associated with other spinal malformations, or iatrogenic, resulting from the implantation of epidermal cells within the spinal canal during the execution of a variety of procedures such as spinal puncture. At MR imaging epidermoid tumors can mimic cystic lesions with fluid content such as arachnoid cysts. DWI can help obtain a correct diagnosis. We describe a case of iatrogenic lumbar epidermoid cyst with DWI findings in a young woman who had undergone epidural anesthesia for Cesarean section three years before the onset of symptoms.

Orbital invasion by squamous cell carcinoma arising in multiple epidermoid cysts.  

Science.gov (United States)

Epidermal or epidermoid cysts usually are benign, solitary-growing masses located in the mid- or lower dermis. They are believed to derive from pilosebaceous units and are lined with an epidermis-like epithelium including a granular cell layer. The occurrence of multiple epidermal cysts on the scalp of nonsyndromic patients is extremely rare. Although the presence of squamous cell carcinoma in the wall of an isolated epidermoid cysts is well documented in the dermatological literature,, the authors are not aware of any article in the English literature describing orbital invasion by a carcinoma developed in isolated or multiple epidermoid cysts.

Resolución espontánea de quiste aracnoideo intracraneal asintomático / Spontaneous resolution of an asymptomatic intracranial arachnoid cyst  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Los quistes aracnoideos son lesiones benignas, de origen congénito y de localización extraparenquimatosa, que con frecuencia se diagnostican de forma incidental en niños y adultos. Su etiología e historia natural no están perfectamente establecidas en la actualidad. La introducción de la tomografía [...] computarizada y resonancia magnética han condicionado un incremento en el número de casos diagnosticados, muchos de ellos de forma incidental. En la literatura existen algunas referencias sobre la desaparición espontánea de quistes aracnoideos intracraneales. Presentamos el caso clínico de un quiste aracnoideo silviano que se redujo progresivamente hasta su resolución a lo largo de un período de 13 años. Revisamos los casos publicados previamente y analizamos los posibles mecanismos causante de su resolución espontánea. Abstract in english Arachnoid cysts are commonly considered to be benign, congenial, extraparenchymatous anomalies. Small cyst are common incidental findings in children and adults. The aetiology and natural history of arachnoid cysts are not fully understood. In most cases, the presence of the cysts is detected on CT- [...] scans or MRI performed for other reasons. In the literature, there have been few documented cases of arachnoid cysts with spontaneous regression. We reports the case of a silvian arachnoid cyst, which disappeared spontaneously during the 13-year-follow-up period. We review the cases previously reported and the mechanisms underlying the resolution of the arachnoid cysts are discussed.

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

Intradural Epidermoid Cyst at Conus Medullaris and Cauda Equina of the Spine: A Case Report  

International Nuclear Information System (INIS)

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.

The patient remains asymptomatic, with reassessment 3 months later. The abdominal ultrasound revealed: fusiform dilatation of the bile duct in its entirety, a finding compatible with type I choledochal cyst Resection was performed, the cyst, cholecystectomy and reconstruction of the bile duct through a hepato-jejunostomy Roux en Y no complications. Liver biopsy reported normal tissue. We conclude that the use of noninvasive imaging tests such as ultrasound is the method of choice due to its sensitivity to determine the presence of cyst and to demonstrate the anatomy of the pancreatic?duct.

[An epidermoid cyst derived from an intrapancreatic accessory spleen].  

Science.gov (United States)

A 43-year-old female patient had high levels of CA19-9 marker; an abdominal ultrasound revealed a cyst. Further investigations with computed tomography (CT), magnetic resonance imaging, and endoscopic ultrasound CT identified a multilocular cystic lesion on the pancreatic tail. An abnormal wall was noted, and different signal strengths were measured in each cyst. Thus, a mucinous cystic tumor was diagnosed, and distal pancreatectomy combined with splenectomy was performed. During the surgery, we identified a multilocular pancreatic cyst with internal bleeding at its distal end. The lesion was ultimately diagnosed as an epidermoid cyst of an intrapancreatic accessory spleen. This diagnosis was based on the histological observation that the vascular construction of the cystic wall was equivalent to that of the spleen, and that its internal tissue was covered by squamous epithelium.

Primary testicular NHL mimicking testicular carcinoma on FDG PET  

International Nuclear Information System (INIS)

A 57-year-old man presented with left testicular swelling. An ultrasound showed a 6cm mass in the left testis and 3 small nodules in the right testis. A CT scan showed left para-aortic nodes and no nodal disease elsewhere. An excisional biopsy of the left testis was followed by an FDG PET scan. A right orchidectomy was then performed. Histology showed diffuse large B cell lymphoma involving both testes and the left spermatic cord. 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

Perspectives for the treatment of epidermoid oesophageal cancer  

International Nuclear Information System (INIS)

Prior to the eighties, most patients with a diagnosis of epidermoid oesophageal cancer only received palliative symptomatic care. To date, most all undergo either surgery or medical treatment or both. Late diagnosis due to lack of clinical signs in the early phases of the disease, and perhaps insufficient attempts at identifying patients at risk who could benefit from systematic screening, is still an important problem although the number of diagnosed cases continues to rise (from 104 in 1985 to 151 in 1989 in Finistere in western France). Two different therapeutic attitudes could improve the prognosis: extensive surgery as proposed by the Japanese with dissection of all invaded lymph nodes whatever the localization and a multimodal approach combining radiochemotherapy and surgery. Although outcome can apparently be improved in certain types of oesophageal cancer, the proposal of aggressive extensive dissection could have an effect on respiratory complications and would not necessarily be adapted to the risk involved in western patients. Certain teams have nevertheless taken this route and will soon report their results. In France two phase II trials combining radiotherapy, chemotherapy (cisplatinium) and surgery have reported encouraging results with complete sterilization in 24% of the cases and 50% survival at 18 months. In our own series of 68 patients, we have obtained 41% sterilization and 56,3% survival at 3 years with the multi-modal protocol. The high number on non-responders to chemotherapy emphasizes the importance of maintaining surgical resection whenever possible. The discouraging reports published before 1980 have been contradicted by improvements in outcome achieved over the last decade. Today, all patients with a diagnosis of epidermoid cancer of the oesophagus should benefit from either palliative or curative care based on the latest advances in radiotherapy, chemotherapy and surgery.

Differentiation between pediatric spinal arachnoid and epidermoid-dermoid cysts: is diffusion-weighted MRI useful?  

Energy Technology Data Exchange (ETDEWEB)

Appropriate differentiation between epidermoid-dermoid and arachnoid cysts is important for patient management. MRI has had limitations in differentiating these two types of cysts, especially in the region of the spinal cord. To evaluate the role of diffusion-weighted (DW) MRI for differentiation between spinal arachnoid and epidermoid-dermoid cysts. Four children underwent conventional and DW MRI. Turbo spin-echo imaging was used to obtain DW images. On conventional MRI, low T1-W and high T2-W signal was present in all lesions. DW imaging showed restricted diffusion in two patients with epidermoid-dermoid cysts and no water restriction in two patients with arachnoid cysts. Three of four children had extramedullary lesions and one patient had an intramedullary lesion. Three children had surgery, two with epidermoid-dermoid cysts and one with arachnoid cyst. Diagnosis was confirmed by histopathology. One child with a thoracic arachnoid cyst had stable clinical imaging findings during a follow-up of 21 months. On conventional MRI, epidermoid-dermoid and arachnoid cysts have similar signal characteristics. Initial experience with spine DW imaging shows promise in differentiating epidermoid-dermoid cysts from arachnoid cysts. Preoperative differentiation is important because it changes management and surgical approach. (orig.)

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.)

Cauda equina syndrome due to implantation epidermoid tumor: After 38 years of surgery for lumbar meningocele in a neonate  

Directory of Open Access Journals (Sweden)

Full Text Available Intraspinal epidermoid tumors are rare. Most of these tumors occur spontaneously, while others may be acquired. Occurrence of epidermoid tumor following surgery for spinal dysraphism has been reported till 15 years from the day of surgery. We report here a case of Cauda equina syndrome due to intraspinal epidermoid tumor following 38 years of surgery for spinal dysraphism. Though epidermoid tumors grow linearly - unlike other tumors, which grow exponentially - we could not find any report in English literature where such a long time of 38 years was taken for the tumor to manifest clinically. The longest period reported for epidermoid tumors to manifest clinically following repair of spinal dysraphism is 15 years. We report this case because it is a case of the longest silent period taken by the implantation epidermoid tumor to manifest clinically.

Estrogen regulation of testicular function  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Evidence supporting a role for estrogen in male reproductive tract development and function has been collected from rodents and humans. These studies fall into three categories: i localization of aromatase and the target protein for estrogen (ER-alpha and ER-beta in tissues of the reproductive tract; ii analysis of testicular phenotypes in transgenic mice deficient in aromatase, ER-alpha and/or ER-beta gene; and, iii investigation of the effects of environmental chemicals on male reproduction. Estrogen is thought to have a regulatory role in the testis because estrogen biosynthesis occurs in testicular cells and the absence of ERs caused adverse effects on spermatogenesis and steroidogenesis. Moreover, several chemicals that are present in the environment, designated xenoestrogens because they have the ability to bind and activate ERs, are known to affect testicular gene expression. However, studies of estrogen action are confounded by a number of factors, including the inability to dissociate estrogen-induced activity in the hypothalamus and pituitary from action occurring directly in the testis and expression of more than one ER subtype in estrogen-sensitive tissues. Use of tissue-specific knockout animals and administration of antiestrogens and/or aromatase inhibitors in vivo may generate additional data to advance our understanding of estrogen and estrogen receptor biology in the developing and mature testis.

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish Las masas cervicales son un motivo de consulta usual dentro de la práctica clínica. Dentro de estas, los nódulos y quistes de origen tiroideo son hallazgos frecuentes. Aún así, existen diagnósticos diferenciales originados de estructuras vecinas a la glándula tiroides, cuyo diagnóstico inicial es di [...] fícil. Presentamos el caso de un varón de 18 años con una masa cervical derecha, clínica y ecográficamente sugerente de un quiste tiroideo. La punción-aspiración con aguja fina fue negativa para células neoplásicas. En el intraoperatorio se identificó una lesión paratraqueal derecha que fue resecada. El diagnóstico histológico fue compatible con un laringocele. El laringocele es una dilatación anormal del sáculo laríngeo que puede simular un quiste tiroideo. La tomografía computarizada y la resonancia magnética son de gran utilidad en su diagnóstico, pero en ocasiones éste se realiza en el intraoperatorio o mediante el estudio anatomopatológico. Abstract in english A cervical mass is a usual complaint within the clinical practice. Among possible causes, thyroid cysts and nodules are frequent findings. However, there are differential diagnoses that arise from neighboring structures, which can be difficult to assess. We report an 18 years old male presenting wit [...] h a cervical mass, clinically and ecographically suggestive of a right thyroid cyst. Fine needle aspiration was negative for neoplastic cells. Within surgery a paratracheal lesion was identified and resected. The histological findings were compatible with a laryngocele. A laryngocele is an abnormal dilatation of the laryngeal sacule that can simulate a thyroid cyst. Computarized tomography and magnetic resonance are of great importance in its diagnosis, but sometimes is found within surgery or in the anatomopathologic study.

No presenta predicción por sexo y alrededor del 60 % de los casos se desarrollan entre los 15 y 35 años de edad. El conocimiento de los hallazgos clínicos de est [...] e tipo lesiones es vital para un diagnóstico definitivo, sin embargo, este siempre debe ser corroborado mediante exámenes histopatológicos, especialmente, al realizar un diagnóstico diferencial entre los diferentes tipos de quiste dermoides u otras alteraciones a nivel oral con manifestaciones clínicas similares. 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.

Sports activities and risk of testicular cancer  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The relationship of testicular seminoma with several factors was explored using a case-control study. Previously recognized associations with cryptorchidism and infantile inguinal hernia were confirmed and relationships were also found with cycling and horse-riding. These findings represent the first relationships of testicular cancer with well-defined postnatal risk factors.

Paediatric benign cystic monodermal testicular teratoma.  

Science.gov (United States)

We present a case of a painless progressively increasing mass in the left upper testis in a 5-year-old boy, which was detected by his father performing testicular examination after observing asymmetry of the scrotum. Clinical examination, tumour markers, ultrasound scan including colour Doppler studies, and finally inguinal exploration and histopathology were helpful in establishing the diagnosis of benign cystic monodermal testicular teratoma. Testicular teratoma should be considered in the differential diagnosis of any child presenting with non-traumatic painless progressive scrotal swelling. Inguinal radical orchiectomy is the traditional gold standard treatment for benign testicular teratoma in children. Testis-sparing surgery should be reserved for smaller testicular tumours known to be benign. PMID:24658524

Congenital epidermoid cyst of the oral cavity: prenatal diagnosis by sonography.  

Science.gov (United States)

Epidermoid cysts are benign developmental anomalies that are rarely observed in the oral cavity of neonate. If large in size, especially in the developing fetus or newborn infant, they can cause swallowing difficulty and occasionally respiratory difficulty. We report a case of epidermoid cyst in the oral cavity detected prenatal sonography. The sonographic finding was large cystic mass, measuring 30×25 mm. In this case, supplies and equipment for an emergency tracheostomy were made available prior to the delivery. However, the infant did not require intervention to secure the airway. The lesion was surgically excised, and histologic diagnosis was epidermoid cyst. After 6 months of follow up, the cyst had not recurred. This case illustrates the value of accurate prenatal diagnosis and planned perinatal management using a team approach. PMID:24069525

Science.gov (United States)

Epidermoid cyst of gastrointestinal tract is very rare, and only a few cases of epidermoid cyst of the caecum have been reported in the literature. We report the first case of epidermoid cyst of the caecum in an elderly man, mimicking mesenteric cyst clinically. It was treated by laparoscopic excision of the cyst. The cyst was spherical, extending from and expanding the serosal surface of the caecum with no communication through the muscularis wall. Histologically, the inner lining of the cyst was composed of benign, mature, keratinised and stratified squamous epithelium with a well-formed granular layer. On opening, the cyst contained pultaceous cheesy material. No calcification, hair, teeth or bone elements were detected. PMID:23302551

A Neglected case admitted with paraplegia: An intradural extramedullary epidermoid cyst  

Directory of Open Access Journals (Sweden)

Full Text Available Spinal epidermoid tumors are rare tumors, constitutingabout 1.5-2% of the spinal tumors. Cervical and thoracicspinal cord epidermoid tumors are exceedingly rare. Wereported a case of a 28-year-old patient with an intraduralextramedullary epidermoid cyst at the thoracic regionpresented with urinary incontinence and paraparesis toour outpatient clinic. First symptoms of patient started 16years ago and diagnosed as peroneal muscular atrophyand he couldn’t be investigated sufficiently. Because ofthe delayed diagnosis and treatment, paraparesis and urinaryincontinence were persistent in spite of successfulsurgery and proper physical therapy. Spinal epidermoidtumors have a good prognosis, as they are histologicallybenign. When diagnosed early, complete surgical resectionoffers the patient good neurologic outcome. It is importantto investigate extensively patients with neurologicaldeficits and to make diagnosis as soon as possible. JClin Exp Invest 2012; 3(2: 270-272

[Testicular toxicity of allyl chloride].  

Science.gov (United States)

In this study, 124 mg/kg of allyl chloride (one-fifth of LD50) was administered to mice by a single subcutaneous injection and its effects on the male reproductive system were evaluated at 4 days, 9 days, 14 days, 22 days and 39 days after treatment. Allyl chloride decreased the weight of the testes, reduced the numbers of spermatid and sperm, and increased the frequency of the morphologically abnormal sperm without any sign of general influence. From these results, allyl chloride was confirmed to be a definite testicular toxicant in mice. Spermatid reduction was already apparent at 4 days after treatment. Therefore, it was found that allyl chloride affected the testis immediately after the injection. Sperm with an abnormal tail (most of them were sperm with a folded tail) increased at the cauda epididymis before the epididymal sperm reduction became apparent. Consequently, it seemed likely that, with its toxic effects on the testis, allyl chloride also affected sperm passing through the epididymis and disturbed their maturation. Spermatid/sperm reduction caused by allyl chloride did not recover and seemed to get worse until 39 days after treatment. The testicular damage caused by allyl chloride was irreversible during this observation period. PMID:9103701

International Nuclear Information System (INIS)

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

The developmental mechanism of this specific finding in the metrizamide CT cisternography was discussed on the basis of morphological characteristics of epidermoid tumor.

Iso-effect tables and therapeutic ratios for epidermoid cancer and normal tissue stroma  

International Nuclear Information System (INIS)

Available literature on radiation injury to normal tissue stroma and ablation of epidermoid carcinoma was surveyed. Computer programs (RAD3 and RAD1) were then used to derive cell kinetic parameters and generate iso-effect tables for the relevant tissues. The two tables provide a set of limiting doses for tolerance of normal connective tissue (16% risk of injury) and for ablation of epidermoid cancer (16% risk of recurrence) covering a wide range of treatment schedules. Calculating the ratios of normal tissue tolerance to tumor control doses for each treatment scheme provides an array of therapeutic ratios, from which appropriate treatment schemes can be selected

Intradiploic epidermoid tumor of the occipital bone: X-ray, CT, MR findings  

Energy Technology Data Exchange (ETDEWEB)

Intradiploic epidermoid tumors are extremely uncommon. About 100 cases have been described in the literature [1]. It is thought that they are caused by inclusion of epitelial ectodermal cells in bone tissue during closure of the neural tube. Most of them are asymtomatic and usually detected when plain skull X-rays are made for other reasons. Others may be detected as a palpable lump. They can erode the inner table protuding into the brain. We report a case of an intradiploic epidermoid tumor of the occipital bone studied with plain skull X-rays, Computed tomography and magnetic resonance imaging. (orig.)

[Segmental testicular infarction in sickle cell anemia].  

Science.gov (United States)

Vascular occlusions are the clinical indicators of sickle cell disease and in urology they can lead to papillary necrosis, renal infarction or priapism. Segmental testicular infarction in patients with sickle cell disease is a rare event and only a few cases have been reported. We present a 25-year-old man with right testicular pain increasing over 3 days and sickle cell disease. Ultrasound of the right scrotum presented an inhomogeneous, mainly hypoechegenic mass with a hyperechogenic margin and no sign of blood flow. A partial orchiectomy was performed with total enucleation of the lesion, which was histologically diagnosed as benign hemorrhagic necrotic testicular tissue. PMID:24705475

Leech therapy for epidermoid cysts and review of the literature  

Science.gov (United States)

Hirudo medicinalis sucks blood directly through the external mammalian skin. We recently observed a healthy 64-year-old Iranian man, who presented with numerous asymptomatic multilobular oval-to-round well-defined 0.5 to 1.5 cm cystic lesions with central umbilication (central black eschar) over the upper portion of his chest. We made the diagnosis of epidermoid cyst, giant comedone and leech bite on the basis of the constellation of clinical features. The patient was treated with oral ciprofloxacin at a dose of 2 g daily, and 2% topical erythromycin solution. Despite improvement, the evidence of cystic lesions persisted. There was no history of similar lesions in any other family member. There was no history of trauma. The patient was not using any topical or systemic medication. Two weeks before his visit, he had a history of leech therapy under the supervision of a general practitioner. His medical history was significant for leech therapy of the lesions, five days previously. He was followed up for another two weeks and after disappearance of the inflammation, with the patient under local anesthesia, the well-circumscribed mass was completely evacuated with a sharp curette and comedone extractor. The patient was subsequently lost to follow-up. Conclusion: Considering the efficacy of leeches, it would be favorable to breed a germ-free leech. In Iran, the use of the leeches in surgery, in recent years, has been infrequent. It appears that the positive effects of this ancient remedy may now be explained through scientific methods, promising potentially even more uses of this admirable creature in medicine.

La enfermedad afecta predominantemente a personas de edad avanzada con un pico de incidencia entre los 60 y 70 años. Desafortunadamente, muchos síntomas experimentados por los pacientes ocurren en estadi [...] os avanzados de la enfermedad, lo cual resulta en un mal pronóstico. 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. Abstract in english Esophageal cancer is a gastrointestinal malignancy with an insidious onset and a poor prognosis. 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.

Presentamos el caso de un varón de 62 años que debuta con un cuadro de desorientación y comportamiento desinhibido tras sufrir un traumatismo craneoencefálico como consecuencia de un accidente de tráfico. En la TC craneal realizada de urgencia se objetiva una lesión quística frontal izquierda de gran tamaño con importante desplazamiento de línea media. Se punciona y evacua el contenido del quiste obteniéndose un líquido opalino rico en proteínas y elementos celulares no identificados. La RMN nos confirma los hallazgos radiológicos previos. El paciente es intervenido de forma reglada mediante craneotomía, evacuación completa del contenido y extirpación de las paredes de la lesión. El estudio anatomopatológico resulta ser compatible con el diagnóstico de quiste endodérmico. Se han descrito casos de evolución agresiva con diseminación y recidiva tras manipulación quirúrgica de la lesión; por lo tanto, el tratamiento debe consistir en la extirpación completa de la misma. Para ello será necesario realizar el diagnóstico diferencial con otras lesiones quísticas intracraneales con el fin de adecuar el tratamiento a cada caso. Abstract in english Endodermal cysts (EC) of the central nervous system are very uncommon lesions predominantly located in the spinal canal. 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.

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.

Cadmium-induced testicular injury  

International Nuclear Information System (INIS)

Cadmium (Cd) is an environmental toxicant and an endocrine disruptor in humans and rodents. 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 and/or regulate the testis sensitivity to Cd, such as Cd transporters and metallothioneins, the impact of Cd on the testis as an endocrine disruptor and oxidative stress inducer, and how it may disrupt the Zn2+ and/or Ca2+ mediated cellular events. While much work is needed before a unified mechanistic pathway of Cd-induced testicular toxicity emerges, 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.

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.

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

DEFF Research Database (Denmark)

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.

Testicular feminization syndrome in a mare.  

Science.gov (United States)

Testicular feminization syndrome was diagnosed in a mare with aggressive, stallion like behavior and a history of infertility. She was found to have a high baseline testosterone concentration suggesting that testicular tissue was present, and ovarian-like structures examined by use of transrectal ultrasonography had the appearance typical of testicular tissue. Although her external female genitalia appeared normal, her vagina ended in a blind sac, and no cervix or uterus were identified. Surgery was performed, and structures removed from the abdominal cavity were determined to be hypoplastic testicles. Removal of the testicular tissue resulted in complete resolution of her aggressive behavior. Chromosomal evaluation revealed that the mare had 64X,Y (normal male) karyotype. Testicular feminization syndrome is a condition characterized by insensitivity of reproductive tissues to androgens during development because of an abnormality in androgen receptors. This androgen insensitivity results in development of normal external female genitalia, with high testosterone concentrations being released from developing testicles. Testicular feminization syndrome has not been commonly diagnosed in horses, but should be considered as a differential diagnosis for overly aggressive mares with a history of infertility.

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.

Magnetic resonance imaging and quantitative analysis of contents of epidermoid and dermoid cysts  

International Nuclear Information System (INIS)

The intracapsular cholesterol protein, and calcium contents of epidermoid and dermoid cysts from seven patients were compared with the signal intensities on T1-weighted spin-echo magnetic resonance (MR) images. All specimens had a paste-like consistency when resected. Epidermoid and dermoid cysts demonstrated a wide range of cholesterol and calcium contents, and epidermoid cysts were not always rich in cholesterol. Five patients had cysts with lower signal intensity than white matter, which contained more than 18.3 mg/g wet weight of protein. One of these patients had the highest cholesterol content of all seven patients (22.25 mg/g wet weight) and another had the highest calcium content (0.75 mg/g wet weight). Two patients had cysts with higher signal intensity than white matter, with protein contents of lower than 4.3 mg/g wet weight. High protein content (>18.3 mg/g wet weight) may decrease signal intensity on T1-weighted MR images, while low protein content (<4.3 mg/g wet weight) may increase signal intensity in epidermoid and dermoid cysts with high viscosity (paste-like consistency) contents.

Malignant transformation of an intracranial large epidermoid cyst with leptomeningeal carcinomatosis: case report.  

Science.gov (United States)

A 64-year-old female presented with rapid onset of left ophthalmoplegia and truncal ataxia, after experiencing diplopia due to left abducens nerve palsy for a year. She had undergone surgery twice for left trigeminal neuralgia caused by a large intracranial epidermoid cyst at the age of 48 and 52 years. The intracranial epidermoid cyst grew and became predominantly enhanced by contrast medium on computed tomography (CT) and T(1)-weighted magnetic resonance (MR) imaging, which had not been observed earlier. The tumor was partially removed and the histological diagnosis was squamous cell carcinoma (SCC). Radiation therapy was administered, but she presented with paraplegia of the bilateral lower extremities and anesthesia due to spinal multiple metastases of SCC one year later. Radiation therapy was administered for the spinal lesions, but she died of multiple metastases to the cerebellum and medulla oblongata with hydrocephalus 2 years after the third surgery. Transformation of intracranial epidermoid cysts to SCC appears as predominant enhancement on CT or T(1)-weighted MR imaging with rapid deterioration of neurological features. All reported cases of malignant transformation of intracranial epithelial cysts to SCC with leptomeningeal carcinomatosis have occurred in intracranial epidermoid cysts. PMID:20448435

Quiste odontogénico ortoqueratinizado: Una nueva entidad derivada del queratoquiste  odontogénico. Revisión de la literatura  

Scientific Electronic Library Online (English)

Full Text Available SciELO Venezuela | Language: Spanish Abstract in spanish Son múltiples los recientes estudios e investigaciones que soportan claramente las diferencias clínicas, histopatológicas e inmunohistoquímicas entre las variantes paraqueratinizada y ortoqueratinizada del Queratoquiste Odontogénico, suscitándose de esta manera controversias entre los diferentes aut [...] ores con respecto a este tema. Sin embargo, son muchos los que ya han fijado su posición y afirman, en base a diferentes hallazgos, que el Queratoquiste odontogénico y su variante ortoqueratinizada, son dos lesiones diferentes e independientes una de la otra. Desde 1981 se introdujo el término de Quiste Odontogénico Ortoqueratinizado, para describir esta entidad patológica que posee unas características bien definidas y cuyas alternativas de tratamiento son conservadoras debido a su baja recurrencia. La presente revisión de la literatura pretende establecer las diferencias entre el Queratoquiste Odontogénico, ya hoy considerado un tumor odontogénico, y el Quiste Odontogénico Ortoqueratinizado como dos entidades independientes.

Nevertheless, those are many that already have fixed their position and affirm, on the basis of different findings, that the odontogenic Queratocyst and its orthoqueratinized variant, they are two injuries different and independent one of the other. From 1981 the term of Orthoqueratinized Odontogénic Cyst was introduced, in order to describe this pathological organization that has defined characteristics affluent and whose alternatives of treatment are preservative due to their low recurrence. The present revision of Literature tries to establish the differences between the Odontogénic Queratocyst, today already considered a odontogenic tumor and the Orthoqueratinized Odontogénic Cyst like two independent organizations.

Radiotherapy for Epidermoid Carcinoma of the Anus: Thirty Years' Experience  

International Nuclear Information System (INIS)

Purpose: To evaluate the factors associated with disease control and morbidity after radiotherapy for anal carcinoma. Methods and Materials: Between 1975 and 2005, 194 patients with localized epidermoid anal carcinoma underwent radiotherapy. Treatment evolved from radiotherapy with or without surgery, to preoperative chemoradiotherapy, to definitive chemoradiotherapy (CRT). The radiotherapy techniques also evolved. Results: With a median follow-up of 61 months, 57 patients had persistence or recurrence, 9 of whom were successfully salvaged, resulting in 146 (75%) ultimately free of disease (UNED). Univariate analysis for UNED survival showed a strong association with the T and N stage (5-year UNED rate, 88.5% ± 3.4% for those with Stage T1-T2N0; 70.1% ± 4.2% for Stage T3N0; and 52.7% ± 6.6% for Stage III; p > .001) and mobility on palpation (5-year UNED rate, 89.2% ± 4.6% for those with mobile tumors vs. 59.3% ± 6.1% for those with tethered/fixed tumor; p > .001). No association was found with gender, age, preoperative vs. definitive CRT, or human immunodeficiency virus status. The 20 human immunodeficiency virus+ patients all received CRT. The radiotherapy factors associated with Grade 3 or greater late morbidity included anorectal morbidity with tumor dose (29% with a dose ?55 Gy vs. 9% otherwise), small bowel injury with technique (9% with anteroposterior-posteroanterior supine vs. 0.7% with multiple fields prone), and bone injury with femoral head dose (9% with a dose of ?44 Gy vs. 0.7% otherwise). Of the 194 patients, 56 had 68 additional malignancies, mainly either antedating the anal cancer or outside the radiation fields. Conclusion: Our results have confirmed that CRT is an effective approach. Patients with human immunodeficiency virus can be treated with CRT. Tumor mobility significantly predicts the outcome; the implications for management are discussed. We also discuss the treatment planning implications of the late morbidity findings. The substantial incidence of additional malignancies underscores the importance of full oncologic screening during follow-up.

[Prognosis of epidermoid anal carcinoma regression after conservative treatment].  

Science.gov (United States)

The prospective study was concerned with definition of the clinical and therapeutic factors behind poor response of anal cancer to radio- (RT) or chemoradiotherapy (CRT). Out of 64 female and 8 male patients at the mean age of 57 (33-81), thirty six had split-course of 60-65 Gy (RT), twenty--60-65 Gy, 5-FU and mitomycin C (CRT) and eighteen--up to 55-65 Gy (1.5 Gy--session 1, 1.0 Gy--session 2) (hyper-fractionated RT) plus 5-FU, for squamous cell anal carcinoma. There was no endorectal ultrasound evidence of perirectal lymph node involvement (uN0): T1-2uN-M0 (n=46), T3-4uN0M0 (n=11), uN1 or N2-3 (groin or endorectal ultrasound: T1-2uN-M0 (n=46), T3-4uN0M0 (n=11), uN1 or N2-3 (groin metastases) were detected in 7 patients: T1-2uN1-2M0 (n=7), T3-4N1-3M0 (n=10). Endorectal ultrasound staging (ERUS) used a linear 7.5 MHz transducer. The uTNM system was devised on the basis of tumor invasion parameters. There were no tumors confined to the subendothelial layer of the anal canal (uT1); 24 (32.4%) tumors were confined to the internal anal sphincter (uT2); 19 (25.7%) invaded the external anal sphincter (uT3) and 31 (41.9%)--levator ani (uT4). All carcinomas T4 (n=9) corresponded to the uT4 category. Only T-stage and tumor invasion (uT) proved significant prognostic variables. Complete response of T1-2 was 79.2%, T3-4--33.3% (p=0.0003); uT2--95.8%, uT3--68.4%, and uT4--41.9% (except T4) (p=0.0001). In multivariate logistic analysis, uT alone appeared an independent variable (p=0.015). ERUS uTNM staging is more effective in prognosis for RT and CRT and, therefore, should be recommended for preliminary management of epidermoid anal carcinoma. PMID:15755059

Lifetime growth and risk of testicular cancer.  

Science.gov (United States)

Adult height is associated with testicular cancer risk. We studied to what extent this association is explained by parental height, childhood height and age at puberty. We conducted a case-control study on germ-cell testicular cancer patients diagnosed in 1997-2008 and resident in the Province of Turin. Information was collected using mailed questionnaires in 2008-2011. Specifically, we asked for adult height (in cm), height at age 9 and 13 (compared to peers) and age at puberty (compared to peers). We also asked for paternal and maternal height (in cm) as indicators of genetic components of adult height. The analysis included 255 cases and 459 controls. Odds ratios (ORs) of testicular cancer were estimated for the different anthropometric variables. Adult height was associated with testicular cancer risk [OR: 1.16, 95% confidence interval (CI): 1.03-1.31 per 5-cm increase]. The risk of testicular cancer was only slightly increased for being taller vs. shorter than peers at age 9 (OR: 1.55, 95% CI: 0.91-2.64) or age 13 (OR: 1.26, 95% CI: 0.78-2.01), and parental height was not associated with testicular cancer risk. The OR for adult height was 1.32 (95% CI: 1.12-1.56) after adjustment for parental height. Among participants with small average parental height (180 cm) vs. short (<174 cm) subjects was 3.47 (95% CI: 1.60-7.51). These results suggest that the association between height and testicular cancer is likely to be explained by environmental factors affecting growth in early life, childhood and adolescence.

Unilateral testicular seminoma with simultaneous contralateral torsion: a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction Testicular germ cell tumors are the most common malignancies in men. Testicular torsion is also a scrotal phenomenon seen in adolescence and adulthood. The co-occurrence of these two scrotal disorders is extremely rare. Case presentation A 28-year-old East Asian man presented at our hospital with painless bilateral scrotal swelling. Both scrotal ultrasonography and computed tomography findings showed bilateral testicular tumors, and magnetic resonance imaging demonstrated a lack of enhancement in his right testis, indicating a hemorrhagic infarction and a left testicular tumor. After a bilateral orchiectomy, the intraoperative and histopathological findings revealed a left seminoma with a complicating contralateral testicular torsion that had developed with hemorrhagic infarction. Conclusion Testicular germ cell tumor with contralateral torsion is extremely rare. We could differentiate this case from bilateral testicular tumors appropriately using magnetic resonance imaging, and suggest that magnetic resonance imaging examination may be necessary to diagnose bilateral testicular masses.

On radiotherapy of testicular tumours  

International Nuclear Information System (INIS)

In the first part of the paper, the general pathological, diagnostical and therapeutical measures against seminomas and teratomas are dealt with. In the second part, the results obtained by the radiotherapeutical division of the University Clinics of Freiburg 1964-1977 in the treatment of seminomas and teratomas are described. The average age of the 59 seminoma patients was 36 years, the average age of the 28 teratoma patients was 26. The 5-years-total survival rate of the seminoma patients was 80.8%, for teratoma patients it was 30.5%. In the individual phases, of all seminoma patients in stage I, 93.1% were still alive after 5 years, in stage II 95.9%, in stage III 12.5%. The 5-years survival rate of the teratoma patients in stage I was around 100%, in stage II around 36.8% and in stage III around 20.5%. In the discussion, the problems of the histological and pathological classification for testicular tumours are talked about and the treatment methods used at the Freiburg university clinics are described. The results obtained in the Freiburg university clinics are compared with those of other authors. (orig./MG)

Peritubular myoid cells have a role in postnatal testicular growth  

Digital Repository Infrastructure Vision for European Research (DRIVER)

FSH stimulates testicular growth by increasing Sertoli cell proliferation and elongation of seminiferous cords. Little is known about the peritubular myoid cells in testicular development. In order to investigate the role of peritubular myoid cells in early testicular growth in rodents, two traditional models to induce testicular growth were used: FSH treatment and hemicastration. In order to affect proliferation of peritubular myoid cells, both treatments were combined with imatinib, a tyros...

Onco-testicular sperm extraction: testicular sperm extraction in azoospermic and very severely oligozoospermic cancer patients.  

Science.gov (United States)

An increased risk of testicular cancer in men with infertility and poor semen quality has been reported. In view of the high cure rates for testicular germ cell tumours, increasing clinical importance is being placed on the protection of fertility. High-dose cytostatic therapy may be expected to cause long-term infertility. Thus, the standard procedure for fertility protection is the cryopreservation of ejaculated spermatozoa or testicular tissue before therapy. Four male patients with azoospermia and two patients with very severe oligozoospermia underwent onco-testicular sperm extraction (TESE). We attempted onco-TESE in patients with azoospermia and very severe oligozoospermia after orchiectomy. Of the patients with testicular germ cell tumours, four had spermatozoa in their testicular tissues. Sertoli cell-only syndrome was found in one patient, and one patient showed maturation arrest without the detection of spermatozoa. Three of six showed seminomatous germ cell tumour, two of six had nonseminomatous germ cell tumour and one patient showed no malignancy. Two patients achieved clinical pregnancy. Fertility challenges in men with cancer are the most straightforward because of the relative ease of obtaining and cryopreserving sperm. Testicular sperm extraction is a useful technique for obtaining spermatozoa before cytotoxic therapy in azoospermic and very severely oligozoospermic cancer patients. PMID:22690948

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.

Segmental testicular infarction following cysto-prostatectomy  

Directory of Open Access Journals (Sweden)

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

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

Se presenta un análisis prospectivo y descriptivo de una serie de 31 casos consecutivos de pacientes portadores de QHH operados entre enero de 200 [...] 6 y enero de 2009, en el Hospital Regional de Coyhaique. Se incluye a todos los pacientes portadores de QHH tipo I, III, los tipo II y IV sintomáticos, menores a 5 cms según la clasificación de la OmS. Previo a la realización de la cirugía se les indicó 15 días de Albendazol y 2 meses en el post-operatorio. La técnica quirúrgica empleada consistió en la evacuación de la membrana parasitaria, resección parcial de la periquística prominente y sutura de las comunicaciones biliares. Siempre se utilizó drenaje. Los 31 pacientes presentaron 40 quistes, 17 de las cuales fueron mujeres, con un promedio de edad de 37 años. El estudio radiológico reveló que el 68,6 de ellos correspondió a quistes univesiculares, siendo únicos en el 74%, localizados principalmente en el lóbulo hepático derecho (68%). Ei tiempo quirúrgico alcanzó a ios 79,83 minutos. Hubo dos conversiones (6,45%), la morbilidad alcanzó al 24%. La estadía promedio fue de 6 días. El período de seguimiento fue de 28 meses, con una recidiva de 3,5%. No hubo mortalidad en esta serie. El costo del tratamiento laparoscópico del QHH promedió los US 2.107. Creemos que la técnica laparoscópica, aplicada con criterio selectivo, es una alternativa útil para el tratamiento de pacientes con hidatidosis hepática, pues sus resultados son comparables a los existentes con cirugía abierta. Abstract in english Background: Laparoscopic surgery is emerging as a useful alternative for the treatment of liver hydatid cysts. Aim: To report technical data, management protocols, costs and results of laparoscopic management of liver hydatid cysts. Material and Methods: Prospective analysis of 31 patients aged 5 to [...] 73 years (17 females), with 40 cysts, operated between 2006 and 2009. All patients received albendazol for 15 days prior to surgery and for 2 months afterwards. Surgical technique consisted in the evacuation of parasite membrane, partial excision of prominent pericystic membrane and suture of biliary communications. Results: Sixty nine percent of cysts were uni-vesicular, 74% were unique and 68% were located in the right lobe. Surgical time was 80 min. Two patients were converted to open surgery and 24% had postoperative complications. Mean hospital stay was six days. Patients were followed for 28 months and in 4% the cyst relapsed. No patient died. The mean cost of laparoscopic treatment was US$ 2.107. Conclusions: Laparoscopic technique is a useful surgical alternative for the treatment of liver hydatid cysts.

Siempre se utilizó drenaje. Los 31 pacientes presentaron 40 quistes, 17 de las cuales fueron mujeres, con un promedio de edad de 37 años. El estudio radiológico reveló que el 68,6 de ellos correspondió a quistes univesiculares, siendo únicos en el 74%, localizados principalmente en el lóbulo hepático derecho (68%. Ei tiempo quirúrgico alcanzó a ios 79,83 minutos. Hubo dos conversiones (6,45%, la morbilidad alcanzó al 24%. La estadía promedio fue de 6 días. El período de seguimiento fue de 28 meses, con una recidiva de 3,5%. No hubo mortalidad en esta serie. El costo del tratamiento laparoscópico del QHH promedió los US 2.107. Creemos que la técnica laparoscópica, aplicada con criterio selectivo, es una alternativa útil para el tratamiento de pacientes con hidatidosis hepática, pues sus resultados son comparables a los existentes con cirugía abierta.Background: Laparoscopic surgery is emerging as a useful alternative for the treatment of liver hydatid cysts. Aim: To report technical data, management protocols, costs and results of laparoscopic management of liver hydatid cysts. Material and Methods: Prospective analysis of 31 patients aged 5 to 73 years (17 females, with 40 cysts, operated between 2006 and 2009. All patients received albendazol for 15 days prior to surgery and for 2 months afterwards. Surgical technique consisted in the evacuation of parasite membrane, partial excision of prominent pericystic membrane and suture of biliary communications. Results: Sixty nine percent of cysts were uni-vesicular, 74% were unique and 68% were located in the right lobe. Surgical time was 80 min. Two patients were converted to open surgery and 24% had postoperative complications. Mean hospital stay was six days. Patients were followed for 28 months and in 4% the cyst relapsed. No patient died. The mean cost of laparoscopic treatment was US$ 2.107. Conclusions: Laparoscopic technique is a useful surgical alternative for the treatment of liver hydatid cysts.

Infarto segmentario de testículo / Segmentary testicular infarction  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish 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.

Ultrasonido de cuello evidenció conducto tirogloso permeable en la línea media con presencia de nódulo hipoecoico, de bordes bien definidos, sin calcificaciones que medía 1,8 x 0,9 cm. Se extirpó la tumoración que medía 3x2, 5x0, 8cm. y se observó cavidad quística de 0,8 cm. de diámetro mayor que contenía material de aspecto gelatinoso. Por debajo de éste, se observó nódulo bien circunscrito de 1,5 cm. de diámetro mayor, constituido por tejido firme de color blanco-amarillento. El estudio histopatológico reveló un quiste revestido por epitelio cilíndrico y respuesta inflamatoria linfohistiocitaria, con células gigantes tipo “cuerpo extraño” alrededor de hendiduras; que correspondían a d dd epósito de colesterol. Conclusión: Se presenta este caso por su rareza y porque puede confundirse clínica e imagenológicamente con una neoplasia maligna. Asimismo, pudiera corresponder al primer caso reportado en nuestro país. 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.

Epidermoid cyst of an intrapancreatic accessory spleen: a case report and literature review  

Science.gov (United States)

Background An epidermoid cyst in an intrapancreatic accessory spleen is a rare lesion. Despite advances in radiologic techniques, in most cases it has been diagnosed preoperatively as a possible pancreatic neoplasm. Case presentation Herein, we present a 63-year-old Caucasian woman, diagnosed preoperatively with enhanced-contrast abdominal computed tomography, as having a potential cystic tumor in the tail of the pancreas. The patient underwent a distal pancreatectomy and splenectomy, and the histological examination revealed the presence of an epidermoid cyst of an accessory intrapancreatic spleen. Conclusions Familiarity with the imaging features, the clinical presentation and the location of the cyst are important to consider if this rare entity is to be included in the differential diagnosis of cystic neoplasms of the pancreas.

Evaluation of lymph nodes on computed tomography images in epidermoid lung cancer  

Energy Technology Data Exchange (ETDEWEB)

This study was undertaken to design the optimal criteria for practical guidelines for lymph node metastasis evaluation in epidermoid lung cancer. Resected lymph nodes (n=214) were analyzed by preoperative computed tomography (CT) images and postoperative histopathological findings. Definite criteria were defined by efficiency, and possible criteria by receiver operating characteristic (ROC) analysis. Statistical values of highest efficiency in 214 lymph nodes revealed that the minor axis offered the best criteria (minor axis 13 mm; efficiency 93%). ROC curve using the minor axis which showed the highest values of sensitivity and specificity in the optimal criteria (minor axis 9.3 mm;sensitivity 76%, specificity 76%). The criteria of the paratracheal lymph nodes were smaller than those of tracheobronchial and subcarinal nodes. In conclusion, it is desirable to evaluate metastasis of lymph nodes by the minor axis, and criteria should be considered changeable to accommodate the anatomical location in epidermoid lung cancer.

Rapid rounding of human epidermoid carcinoma cells A-431 induced by epidermal growth factor  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Epidermal growth factor (EGF) induces rapid rounding of A-431 human epidermoid carcinoma cells in Ca(++)-free medium. Cell rounding is not induced by a variety of other polypeptide hormones, antiserum to cell membranes, local anesthetics, colchicine, cytochalasin B, or cyclic nucleotides. However, trypsin, like EGF, induces rounding of A- 431 cells in the absence of Ca(++). Both trypsin- and EGF-induced rounding are temperature dependent, appear to be energy dependent, and are inhibited by cy...

Objetivo: Dada la baja frecuencia de la torsión testicular in útero y la escasez de publicaciones en nuestro medio, consideramos importante mostrar nuestra experiencia. Caso clínico:recién nacido de término, de 41 semanas, adecuado para la edad gestacional; al examen físico post parto se encuentra un testículo izquierdo de consistencia pétrea e hidrocele derecho. Se le realizó ecotomografía doppler color, que sugiere el diagnóstico de torsión testicular in útero. Posteriormente, es intervenido realizando una orquiectomía con fijación testicular contralateral y se envía muestra a necropsia. La evolución en el post operatorio inmediato y tardío fue buena. Conclusión:En la torsión testicular in útero es muy infrecuente salvar el testículo afectado, su manejo adecuado y a tiempo permite la viabilidad del testículo contralateralTesticular torsion can occur during foetal life or in the newborn, it is not a very frequent pathology. Objective:Given the low frequency of testicular torsion in-utero and the few published cases, we consider it important to demonstrate our clinical experience. Clinical case: A 41 week term infant, appropriate for gestional age, who had a left testis of stony consistency and right hydrocoele on physical examination. Colour doppler ultrasound suggested the diagnosis of testicular torsion in-utero. An orquidectomia with fixation of the contralateral testis was performed, and the sample sent for histology. Post-operative recovery was without incident. It is very infrequent to save the affected testicle, appropriate diagnosis and treatment permits the viability of the contralateral testicle to be maintained

Magnetic resonance imaging of epidermoid, including diffusion weighted images and an atypical case  

International Nuclear Information System (INIS)

In order to study the role of magnetic resonance imaging (MRI) in diagnosing intracranial epidermoid, we evaluated the MRI findings on five cases with such tumor, all of which were surgically verified. In addition to standard spin-echo (SE) images obtained in all cases, diffusion-weighted images were acquired in two patients. In four patients, the tumor revealed to be almost isointense relative to cerebrospinal fluid (CSF) on both T_1-and T_2-weighted images, while it tended to show slightly hyperintense to CSF on proton-density-weighted images; thus, based on the signal intensity on standard SE images the distinction between epidermoid and arachnoid cyst may be difficult. Furthermore, the presence of the tumor which has a tendency to grow in and along the subarachnoid space causing relatively minimal mass effect may be overlooked. Diffusion-weighted images were shown to have advantages in such cases by demonstrating the tumor unequivocally as a mass of high signal, and differentiating it from arachnoid cysts. In the remaining patient, its appearance was atypical, showing bright signal on both T_1-and T_2-weighted images. In conclusion free of bone artifacts, multiplanar MRI with additional diffusion-weighted images provides a clear demonstration of epidermoid, and its differentiation from arachnoid cyst, thus obviating the need for CT cisternography.

Two cases of epidermoid in the fourth ventricle with characteristic findings of metrizamide CT cisternography  

International Nuclear Information System (INIS)

Two cases of epidermoid in the fourth ventricle with characteristic findings of metrizamide CT sisternography (M-CT) were reported. The M-CT findings of the two cases showed a cauliflower-like, irregular, high-density lesion in the low-density area which was not observd in the conventional enhanced CT. In one case, the characteristic finding was observed in the M-CT after the injection of metrizamide through a spinal puncture. In the other case, however, the finding was obtained only when metrizamide was administered in the lateral ventricle through the shunt valve. After the injection of metrizamide into the lateral ventricle through the shunt valve in one case, the concentration of metrizamide in the small irregular cyst of the epidermoid was measured during the operation. A high concentration of metrizamide was observed in the cyst fluid; this proved that metrizamide could enter the cyst through the tumor capsule. The irregular, high-density lesion in the low-density area observed in the M-CT seemed to be a pathognomonic finding with regard to intracranial epidermoids. (author)

Radiosurgery of epidermoid tumors with gamma knife. Possiblity of radiosurgical nerve decompression  

International Nuclear Information System (INIS)

Long-term results of radiosurgery for epidermoid tumors are reported. There are 7 cases including 2 males and 5 females, ages ranging from 6 to 46 (mean: 33.3 years). At radiosurgery whole tumor was covered in 4 cases and partially covered in 3 cases in attempting to relieve cranial nerve signs like trigeminal neuralgia and facial spasm. The mean maximum and marginal doses were 25.6 Gy and 14.6 Gy respectively. In the mean follow-up of 52.7 months, all the tumors showed good tumor control without any progression and tumor shrinkage has been confirmed in 2 out of the 7 cases. Symptomatic trigeminal neuralgia improved or disappeared in all 4 cases and facial spasm disappeared in one. No neurological deterioration was found in any of the cases after the treatment. In conclusion, it is apparent that epidermoid tumors do respond well to radiosurgery and the accompanying hyperactive dysfunction of cranial nerves is significantly improved by gamma knife treatment with either entire or partial tumor coverage. Therefore the radiosurgical nerve decompression for epidermoid tumor seems to be achieved by gamma-radiosurgery. (author)

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)

Microdissection testicular sperm extraction: an update.  

Science.gov (United States)

Patients with non-obstructive azoospermia (NOA) were once considered to be infertile with few treatment options due to the absence of sperm in the ejaculate. In the last two decades, the advent of intracytoplasmic sperm injection (ICSI), and the application of various testicular sperm retrieval techniques, including fine needle aspiration (FNA), conventional testicular sperm extraction (TESE) and microdissection testicular sperm extraction (micro-TESE) have revolutionized treatment in this group of men. Because most men with NOA will have isolated regions of spermatogenesis within the testis, studies have illustrated that sperm can be retrieved in most men with NOA, including Klinefelter's syndrome (KS), prior history of chemotherapy and cryptorchidism. Micro-TESE, when compared with conventional TESE has a higher sperm retrieval rate (SRR) with fewer postoperative complications and negative effects on testicular function. In this article, we will compare the efficacy of the different procedures of sperm extraction, discuss the medical treatment and the role of testosterone optimization in men with NOA and describe the micro-TESE surgical technique. Furthermore, we will update our overall experience to allow counseling on the prognosis of sperm retrieval for the specific subsets of NOA. PMID:23241638

GPER signaling in spermatogenesis and testicular tumors  

Directory of Open Access Journals (Sweden)

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.

Automated sonographic evaluation of testicular perfusion  

International Nuclear Information System (INIS)

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

Hematoma subdural crónico asociado a quiste aracnoideo: Presentación de 12 casos / Chronic subdural hematoma associated with arachnoid cyst: Report of 12 cases  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Objetivos. Analizar las características clínicas, neurológicas y resultado neurorradiológico de una serie de pacientes con quiste aracnoideo asociado a un hematoma subdural crónico. Pacientes y método. Revisamos retrospectivamente 12 casos de pacientes con quiste aracnoideo que presentaron como comp [...] licación un hematoma subdural crónico. Resultados. 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.

Peritubular myoid cells have a role in postnatal testicular growth.  

Science.gov (United States)

FSH stimulates testicular growth by increasing Sertoli cell proliferation and elongation of seminiferous cords. Little is known about the peritubular myoid cells in testicular development. In order to investigate the role of peritubular myoid cells in early testicular growth in rodents, two traditional models to induce testicular growth were used: FSH treatment and hemicastration. In order to affect proliferation of peritubular myoid cells, both treatments were combined with imatinib, a tyrosine kinase inhibitor. In addition, effects of imatinib on human testicular peritubular cell proliferation were investigated. Testicular weight, diameter and length of seminiferous cords, numbers of germ, Sertoli and BrdU-positive cells and FSH-levels were measured. FSH treatment and hemicastration increased length of the seminiferous cords and testicular weight by increasing first the early proliferation of peritubular myoid cells and later also the proliferation of the Sertoli cells. Imatinib blocked the FSH and hemicastration -induced testicular hypertrophy and decreased the proliferation of PDGF-stimulated human testicular peritubular cells in vitro. Present results provide new evidence that peritubular myoid cells have an important role in postnatal testicular growth. PMID:22670217

Técnicas de purificación y ruptura de quistes de Giardia spp Purification and breaking techniques of cysts of Giardia spp  

Directory of Open Access Journals (Sweden)

Full Text Available El objetivo de este trabajo fue optimizar y evaluar las técnicas de purificación, aislamiento y ruptura de quistes de Giardia spp a partir de heces formoladas para la obtención de ADN. La materia fecal filtrada fue sometida a 3 técnicas de purificación, utilizando soluciones de formol-éter, sacarosa y formol-éter más sacarosa. La solución de sacarosa permitió aislar los quistes con menos detritos. Los quistes purificados fueron tratados con 3 técnicas para la ruptura de los mismos: shock osmótico y calor, degradación química y shock térmico, acción enzimática y efecto mecánico. Solamente con la técnica de shock térmico, acción enzimática y efecto mecánico se observaron bandas fluorescentes en geles de agarosa. Los resultados de este trabajo permiten contar con una metodología de rutina, simple, que podría ser usada en los pasos previos a la técnica de PCR para la genotipificación de este parásito.The purpose of this study was to optimize and evaluate the purification techniques, isolation and breaking of cysts of Giardia spp from fecal samples to isolate DNA. Filtrated fecal samples were tested in 3 purification techniques: Telleman solution, sucrose and Telleman plus sucrose. The sucrose solution let us to isolate the cysts with less detritus. The cleaned cysts were splited in 3 techniques to test the breaking: osmotic shock and heat, chemistry degradation and thermic shock, enzymatic action and mechanic effect. Only the last method was successful and showed bands in agarose gel. The result of this study shows a routine and common method which could be used in the previous steps to the PCR technique for the genotypification of these parasites.

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

DEFF Research Database (Denmark)

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.

Combined regional chemotherapy and radiation therapy in the treatment of epidermoid carcinoma in the oro-facial region.  

Science.gov (United States)

Followed treatment of oro-facial epidermoid carcinoma by combined chemo- and radiation therapy with eventual surgical intervention. Cytostatic drugs were applied intraarterially. After a monocytostatic treatment trial with Methotrexat (MTX), a combined cytostatic program was worked out utilizing two cytostatic drugs, viz. MTX and Bleomycin (BLM) in a cyclic alternation. Usefulness of chemotherapy and its inclusion into the treatment of epidermoid carcinoma in the oro-facial region was found justified principally in the case of combined therapy. However, the selected intraarterial mode of cytostatic administration is attended by certain drawbacks, mainly of a technical nature and is not suitable for routine application. For this reason, the authors have abandoned the i. a. mode of cytostatic administration in epidermoid oro-facial carcinoma and have adopted systemic application and this in combination with radiation, eventually surgical therapy with the utilization of chemotherapy.

Late onset Proteus Mirabilis Meningitis and Subdural Abscess in a Boy With Lumbosacral Epidermoid Tumor: Case Report  

Directory of Open Access Journals (Sweden)

Full Text Available Dermal sinus tracts have been reported all along the midline neuroaxis, with the majority being located in lumbar and sacral areas. They are usually associated with split cord malformations, tethered cord and inclusion tumors (dermoid, epidermoid, teratoma. Dermal sinus tracts with concomitant dermoid or epidermoid tumors are frequently associated with recurrent meningitis, but spinal subdural abscess is rare. The authors report a 2 years old boy with lumbar epidermoid tumor, late onset Proteus mirabilis meningitis and spinal intradural abscess, who had a history of a dermal sinus tract removal one year before his admission. The importance of early diagnosis, proper surgical and medical treatment and close follow up in such patients is stressed.

Transverse testicular ectopia detected by MR imaging and MR venography  

International Nuclear Information System (INIS)

Crossed testicular ectopia is a rare anomaly, characterised by migration of one testis towards the opposite inguinal canal. In most reported cases, the correct diagnosis was not made pre-operatively. We report a case of transverse testicular ectopia diagnosed pre-operatively with MRI. MRI and MR venography demonstrated unilateral location of both testes in the right inguinal canal, which was confirmed by surgery. We provide a brief literature review of transverse testicular ectopia and the imaging of undescended testis. (orig.)

Late solitary testicular metastasis from rectal cancer  

Directory of Open Access Journals (Sweden)

Full Text Available Isolated testicular metastasis from rectal cancer is rare. We describe the case of a patient who presented with a locally advanced rectal malignancy and underwent multimodality treatment with low anterior resection, postoperative radiotherapy and adjuvant chemotherapy. He developed a painless testicular nodule while on follow-up, five years after the diagnosis of primary rectal cancer. Histopathology and immunohistochemistry of orchidectomy specimen were compatible with a metastatic adenocarcinoma of rectal origin. We hypothesize that this phenomenon of isolated relapse in a sanctuary site could be due to the altered biology and pattern of metastasis as a result of effective adjuvant systemic chemotherapy. Treatment of late isolated relapse in the testis needs to be ascertained.

Testicular dysgenesis syndrome and Leydig cell function  

DEFF Research Database (Denmark)

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

Testicular tumors - clinical aspects and therapy  

International Nuclear Information System (INIS)

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

Evaluation of biomarkers for testicular toxicity  

Digital Repository Infrastructure Vision for European Research (DRIVER)

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 ...

[A case of testicular torsion in a neonate].  

Science.gov (United States)

A case of testicular torsion in a neonate is reported. A two-day-old boy with an abnormal hard mass in the right scrotum was referred to us. Right testicular torsion was suspected and operation was performed at 13 days after birth. During the operation extra-vaginal torsion of the right spermatic cord was revealed. The right testis appeared extensively necrotic, and right orchiectomy was selected. Histological examination revealed massively coagulo-necrotic testicular structure. To our knowledge, this is the 56th case of testicular torsion in a neonate reported in Japan. We discussed the onset, laterality, form, direction, angle and treatment of the torsion. PMID:1785401

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

Characteristic findings of metrizamide CT cisternography in an epidermoid in the posterior fossa  

Energy Technology Data Exchange (ETDEWEB)

A case of epidermoid cyst in the posterior fossa showing a characteristic finding upon metrizamide CT cisternography is reported. A 42-year-old man was admitted with gait disturbance. The abnormal signs were trunucal ataxia, gait ataxia, left cerebellar sign and nystagmus. A CT scan revealed a large, low-density area and the fourth ventricle could not be seen clearly. Absorption values were in the range of 5 - 18 Hounsfield units. There was no change in the absorption values of the lesion following intravenous injection of contrast medium. Metrizamide CT cisternography was performed No remarkable change was seen 1 hour after intrathecal injection of metrizamide. However, metrizamide irregularly surrounded the left margin of the low-density area 3 hours after intrathecal injection. Moreover, metrizamide stained the area heterogeneously like a honeycomb or sponge at 6 hours. Finally, only a small amount of metrizamide remained in this area after 24 hours. Suboccipital craniectomy revealed a pearly tumor in the cisterna magna, wrapped in a thin white capsule and partially adherent to the cerebellomedullary junction. The tumor was totally removed. Histopathological investigation showed stratified squamous epithelium with keratinous material. A honeycomb- or sponge-like image seems to be a characteristic finding in metrizamide CT cisternography of the epidermoid cyst. This finding has not been previously reported. However, pneumoencephalographical findings in some cases of epidermoid were reported as crumb- or sponge-like images. These images were thought to be caused by air covering the surface of the pearly tumor. These images should be similar to the one found in the present study using CT cisternography.

Results of radial therapy epidermoid of lungs cancer with dynamic fractionating dozes  

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 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

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.

Radiotherapy Treatment Planning for Testicular Seminoma  

Energy Technology Data Exchange (ETDEWEB)

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

Ultrasonographic Findings of Prepubertal Testicular Teratoma  

Energy Technology Data Exchange (ETDEWEB)

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

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.

Tradicionalmente, se ha recomendado la remoción del quiste mediante el procedimiento de Sistrunk. Se describe una modificación de la técnica quirúrgica, preservando el cuerpo del hioides. El objetivo del presente estudio fue evaluar la frecuencia de complicaciones perioperatorias y de recidiva después del procedimiento quirúrgico modificado. Materiales y métodos. Se hizo un análisis retrospectivo de una cohorte de pacientes sometidos entre marzo de 2003 y marzo de 2011 a la resección quirúrgica del quiste del conducto tirogloso con el procedimiento modificado. Las intervenciones fueron practicadas por un cirujano de cabeza y cuello de la Fundación Cardioinfantil (Bogotá). Resultados. En el estudio se incluyeron 43 pacientes que cumplían los criterios de inclusión. La mediana de seguimiento fue de 11 meses y la tasa de complicaciones fue 6,9 % (n=3). Se presentaron dos granulomas a cuerpo extraño y un mucocele, este último considerado como una recidiva (2,3 %). Discusión. En el presente estudio no se encontró un incremento en la frecuencia de complicaciones perioperatorias cuando se reseca el quiste del conducto tirogloso con la técnica modificada.

Traditionally it has be [...] en recommended the removal of the cyst by the Sistrunk procedure. The authors describe a modified surgical technique that preserves the hyoid bone. 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.

Quiste hidatídico mediastínico: Reporte de un caso y revisión de la literatura Mediastinal hydatid cyst: Case report and review  

Directory of Open Access Journals (Sweden)

Full Text Available La hidatidosis es una parasitosis producida por la larva o quiste del cestodes del género Echinococcus. Una vez que el parásito infecta al hombre se ubica, en más de 90% de los casos, en hígado o pulmón. La localización mediastínica sin afección pleuropulmonar previa es extremadamente infrecuente. En Chile no hay reporte de casos con tal ubicación. Se presenta el primer caso en Chile de un quiste hidatídico (QH mediastínico: el caso de una mujer de 38 años que consultó por aumento de volumen doloroso supraclavicular derecho, asociado a disnea de esfuerzo y disfagia lógica, cuyo estudio preoperatorio mostró un tumor de mediastino con extensión cervical de aspecto nodal y de naturaleza incierta. Se operó con éxito en nuestro hospital, comprobándose durante la operación y por la biopsia, el diagnóstico de QH mediastínico. Adjuntamos las imágenes más relevantes y las fotografías de la operación y la pieza quirúrgica, como también una revisión de la literatura médicaHydatid disease is caused by the larval stages of a cestodes belonging to the genus Echinococcus. In humans, hydatid larva and cysts are located > 90% in the liver and/or lungs. Primary mediastinal location, with absence of documented lung infection, is extremely rare and has not been previously reported in Chile. We report the first case of a primary mediastinal hydatid cyst in Chile and review the literature. A 38 year old woman was admitted because of a painful right supraclavicular mass, dyspnea on exertion and logical dysphagia. Presurgical evaluation evidenced a mediastinal tumor extending to the cervical region that was successfully removed. The diagnosis of mediastinal hidatyd cyst was confirmed macroscopically and by biopsy

Quiste del mesenterio: reporte de un caso y revisión de la literatura Mesenteric cyst: a case report and literature review  

Directory of Open Access Journals (Sweden)

Full Text Available El quiste mesentérico es una entidad poco frecuente que se ha definido como cualquier lesión quística localizada en el mesenterio, y se subdivide, según su origen, en tumores linfáticos, mesoteliales, urogenitales, dermoides, entéricos y seudoquistes. Recientemente atendimos en nuestro hospital a un paciente del sexo masculino, de 61 años de edad, ingresado a causa de dolor abdominal difuso, que se llevó al salón de operaciones con el diagnóstico de oclusión intestinal por bridas. Durante el acto quirúrgico se encontró un quiste del mesenterio, aproximadamente de 8 a 10 cm, por lo que fue necesario realizar una resección intestinal, siendo la evolución posoperatoria favorable. La baja incidencia de la enfermedad y la creencia errónea de que se trata de un proceso benigno y asintomático han contribuido al escaso interés por su conocimiento.The mesenteric cyst is an uncommon entity localized in the mesentery and it is subdivided, according to its origin into lymphatic, mesothelial, urogenital, dermoid, or enteric tumors, and pseudocysts. Recently. we received in our hospital a 61-year-old male patient that was admitted due to a diffuse abdominal pain. He was taken to the operating room with the diagnosis of intestinal occlusion caused by bands. During the surgical procedure, it was found a mesenteric cyst of approximately 8-10 cm, which made necessary to perform intestinal resection. The postoperative evolution was satisfactory. The low incidence of the disease and the erroneous belief that it is a benign and asymptomatic process have contributed to the little interest in knowing about it.

Quiste mesotelial simple gigante abdomino-pélvico Giant pelvic and abdominal omental cyst. Report of one case  

Directory of Open Access Journals (Sweden)

Full Text Available Se presenta el caso de una mujer de 41 años que consulta por dolor abdominal y pelviano de carácter sordo de 6 semanas de evolución sin compromiso del estado general. Refiere el antecedente de una histerectomía por mioma realizada hace 3 años. La ecotomografía y la TAC de abdomen y pelvis revelan una lesión quística gigante de 15 x 8 x 12 cm que ocupa parte del abdomen y la pelvis. Luego de una resección parcial y marsupialización es referida a cirugía por recidiva precoz del tumor quístico. Es reintervenida, lográndose una extirpación completa más anexectomía bilateral con buena evolución posterior. El estudio histopatológico confirma el diagnóstico inicial de quiste mesotelial simple. La ubicación pelviana de la lesión, el comportamiento clínico (recidiva precoz con crecimiento rápido y las dimensiones son más característicos de un mesotelioma quístico benigno. Sin embargo, el carácter unilocular permite catalogarlo como un quiste mesotelial de crecimiento excepcional. La distinción entre ambas entidades no es menor, toda vez que el mesotelioma quístico benigno tiene una recidiva alta y puede malignizarseWe report a 41 years old women presenting with abdominal and pelvic pain lasting six weeks. 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

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 res [...] ection 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

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 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.)

Testicular (gonadal stromal fibroma: Case report  

Directory of Open Access Journals (Sweden)

Full Text Available Testicular fibroma is a rare benign tumor of gradual growth, usually in the third and fourth decade, in the form of a hypoechogenous nodule with clear boundaries and is usually not accompanied by hormonal abnormalities. Metastasis and recurrence of disease were not noted. A 40-year-old male saught medical attention due to pain in the lower back that spread to the pubic bones and the groin. During physical examination, a painless nodule with clear boundaries was palpated in the right testicle, and the ultrasonographic examination revealed hypoechogenic zone with vague boundaries of about 10 mm in diameter. Standard biochemical analyses of blood and urine tests and tumor markers (CEA, CA 125, CA 19-9, AFP and ?HCG were within the physiological limit. Histopathologic analysis set a diagnosis of testicular fibroma. The absence of sex cords in the tumor tissue made it possible to diagnose the patient using standard staining methods, but in cases where these elements can be histologically verified, immunohistochemical analysis should be introduced into a routine diagnostic algorithm.

Modulation of testicular macrophage activity by collagenase  

Directory of Open Access Journals (Sweden)

Full Text Available Testicular macrophages (TMs are located in the interstitial tissue of male gonad. These phagocytic cells take part in forming the organ-specific functional blood-testis barrier and participate in the regulation of the local hormonal balance. In the present study, we isolated TMs from testicular tissues using previously described methods - mechanical (M-TMs or enzymatic, by treatment with collagenase (E-TMs and then we studied production by these cells of several cytokines and reactive oxygen intermediates (ROI’s. Similarly treated oil-induced peritoneal macrophages (PMs were used as control cells. PMs had a higher baseline level of production of TNF-?, IL-6, IL-10 and IL-12 than M-TMs and collagenase treatment increased the production of these cytokines (except IL-12 by both cell populations. This effect was significantly more expressed in TMs. In contrast to PMs, TMs produced little ROI’s when stimulated by zymosan. We conclude that in the case of local inflammation in the testis, ROI-negative TMs do not contribute to the tissue damage and instead may direct the local immune response into humoral pathway.

Inguinal sentinel node biopsy in epidermoid carcinoma of the anal canal: a pilot study  

International Nuclear Information System (INIS)

It has been well established that the primary therapeutic approach to anal squamous-cell carcinoma is chemoradiotherapy. Inguinal lymph node (LN) status is an important prognosis indicator and the presence of metastases in the inguinal LN is an independent marker of the local failure and overall survival. The appropriate management of patients with primary anal cancer and clinically uninvolved groins remains controversial. Nowadays there is no reliable diagnostic method to accurately determine nodal status of the inguinal region. This study was conducted to evaluate the feasibility of a novel assessment method of the nodal status of the inguinal region in patients with epidermoid carcinoma of the anus and anal margin. We advocate that sentinel lymph node biopsy is a safe and feasible technique to detect metastases in inguinal nodes. (author)

Pulmonary epidermoid carcinoma in a patient with acromegaly: a rare entity.  

Science.gov (United States)

A 56-years-old woman was referred to our unit for partially treated acromegaly. She had a high level of insulin growth factor. She did not complain of any pulmonary symptoms and was a non-smoker. Physical examination revealed clinical features of acromegaly. She had a 13 mm pituitary adenoma and was proposed for surgical intervention. Her chest X-ray showed a right paracardiac tumor. Computed tomography scan revealed a large right-sided fowler tumor. Pituitary surgery was cancelled and lobectomy after biopsy with lymph nodes excision was performed through thoracotomy. Histological study of the tumor revealed a medium differentiated epidermoid carcinoma with positive lymph nodes and extension to pleura. She was referred to chemotherapy protocol. Association between carcinoma and acromegaly has previously been reported. Most common tumors are colorectal and thyroid neoplasia. As we see in this case report, we need to consider other carcinomas in acromegalic patients like pulmonary carcinoma, despite their rarity in women. PMID:22891085

Children fathered by men treated for testicular cancer  

International Nuclear Information System (INIS)

Children fathered by 27 testicular cancer patients treated with radiotherapy, 25 treated with chemotherapy, and 57 control men (46 community control and 11 Stage I testicular cancer patients) were examined for evidence of congenital malformations. The proportion of malformations in children in the treatment group did not differ from that in children in the control group or from incidence rates for malformations in the general population. Our results suggest that treatment for testicular cancer should not constitute a reason for advising termination of pregnancy, although numbers were too few to detect a relative risk smaller than 3.2. More observations are needed to provide a definite answer. (author)

The possible role of hemochromatosis in testicular cancer.  

Science.gov (United States)

Hemochromatosis is a genetic disorder of iron metabolism that results in elevated iron absorption in the intestines, which leads to progressive iron accumulation in a variety of organs. Studies have shown that excessive iron deposits in the liver due to hereditary hemochromatosis leads to cirrhosis, which can put an individual at increased risk for developing hepatocellular carcinoma. Testicular atrophy, sometimes caused by excessive iron deposition in the testes, is a risk factor for testicular cancer. Therefore, the possible role of hereditary hemochromatosis in testicular cancer is explored. PMID:21549511

Germinative testicular cells and bone marrow mononuclear cells transplanted to a rat model of testicular degeneration.  

Science.gov (United States)

The aim of this study was to evaluate the ability of rat mononuclear bone marrow cells to recover testis cell associations and multiplication in busulfan-treated rats, and to compare these data to germinative testicular cell transplant. The germinative testicular cells were obtained by the trypsin digestion method, and bone marrow cells were harvested from femurs and tibias, and purified using by Ficoll gradient. Cell transplantation was performed by the injection of cells through the efferent ducts into the rete testis in busulfan-treated animals. Fifteen days after transplantation, the recipient rats were sacrificed and the testes were collected and analyzed by histology (hematoxilin-eosin and DAPI staining). Results demonstrated that germ cells transplantation promoted cellular reorganization of seminiferous epithelium 15 days later. On the other hand, no improvement in spermatogenesis regeneration was found after heterologous mononuclear bone marrow cell transplantation. PMID:18795870

Tratamiento quirúrgico conservador del quiste dentígero en pacientes pediátricos atendidos en el postgrado de cirugía bucal facultad de odontología de la UCV: Seguimiento a largo plazo  

Scientific Electronic Library Online (English)

Full Text Available SciELO Venezuela | Language: Spanish Abstract in spanish RESUMEN De acuerdo a numerosos autores el tratamiento para el quiste dentígero ha sido la eliminación total del quiste incluyendo el diente involucrado aunque si la lesión se presenta en pacientes jóvenes que están en período de erupción dentaria y las características clínicas y radiográficas sugier [...] en la presencia de un quiste dentígero, existe una alternativa de tratamiento la cual es la de mantener el diente permanente no erupcionado y enuclear completamente la lesión, siempre que se obtenga el diagnóstico definitivo histopatológico confirmatorio de quiste dentígero. Se realizó un estudio clínico en 12 pacientes de 7 a 16 años de edad con un promedio de 9,4 años, quienes fueron tratados en el Postgrado de Cirugía Bucal de la Facultad de Odontología de la Universidad Central de Venezuela (UCV). Todos los pacientes tenían las características clínicas y radiográficas similares a las del quiste dentígero, se encontraron 5 mujeres y 7 hombres, los cuales fueron sometidos a biopsia excisional, donde se les eliminó la lesión por completo, dejándoles el diente permanente no erupcionado. Las lesiones eran en la mandíbula y las imágenes radiolúcidas eran bien delimitadas al cuello dentario y menores a 2,5 cms. de diámetro. Los pacientes con quiste dentígero asociado a un tercer molar fueron excluídos del estudio. El estudio histopatológico fue confirmatorio de quiste dentígero para cada paciente y a cada uno se les realizó un seguimiento clínico y radiográfico periódico desde 2 meses hasta 7 años, con un intervalo aproximado de cada 6 meses. (1999-2006). No se encontraron imágenes radiolúcidas en ninguna de las radiografías post-quirúrgicas. Todos mostraron nueva formación ósea alrededor del diente involucrado y erupción completa de la dentición permanente. Tres(3) pacientes fueron seguidos por 7 años, cuatro(4) por 5 años, dos(2) por 3 años con 9 meses y tres(3) por 2 años y 6 meses. A dos(2) de los pacientes se les realizó tratamiento ortodóncico para corregir su maloclusión. Preservar el diente involucrado en un Quiste Dentígero al enuclear totalmente la lesión es una alternativa de procedimiento quirúrgico  con resultados clínicos y radiográficos predecibles y estables. Este tratamiento puede ser usado como un manejo quirúrgico conservador que permite la erupción normal de la dentición permanente. Éste estudio enfatiza la importancia del manejo multidisciplinario en equipo (Cirujano Bucal, Patólogo Bucal, Ortodoncista y Odontopediatra) y el control radiográfico postquirúrgico contínuo de los pacientes para asegurarnos de que no ha habido recidiva o la aparición de alguna nueva patología asociada Abstract in english ABSTRACT According to most authors the common treatment for the dentigerous cyst has been total elimination of the cyst including the tooth involved; however if the lesion is present in young patients during the eruption period, and the radiographic and clinical features are suggesting of dentigerou [...] s cyst, an alternative treatment is the maintenance of the permanent tooth and enucleation of the lesion alone, stating that ameloblastomatous changes or other odontogenic lesions have been ruled out after histopathological analysis, and a diagnosis of dentigerous cyst is confirmed. This study was conducted on 12 patients with an age range of 6 to 16 years with a mean age of 9.4 years that were treated at the Oral Surgery Postgraduate Department, Dental School, Central University of Venezuela. There were 5 females and 7 males. All lesions were mandibular and all of them were unilocular and well-defined radiolucencies measuring less than 2,5 cms in greatest diameter. All cases involved the coronal portion with cervical attachment of an unerupted permanent tooth. Third molars were excluded. Patients underwent surgery (excisional biopsy) of the cyst with preservation of the involved tooth. Histologic diagnosis of dentigerous cyst was confirmed in each case. Clin

Interstitial brachytherapy in the treatment of oropharyngeal epidermoid carcinomas (256 pts)  

International Nuclear Information System (INIS)

Purpose: the objective of this study is to report the results of interstitial brachytherapy [BT] used as exclusive treatment or as a boost in a large series of velo-tonsillar or glosso-tonsillar epidermoid carcinomas. Materials and methods: from 1982 to 1995, 256 patients (230 men and 26 women; average age: 60 years), with oropharyngeal epidermoid cancer as described above have been treated with 192 Iridium LDR interstitial BT: 218 primary tumors [PT] (39 T1, 103 T2, 74 T3, 2 T4) and 38 second primary tumors [SPT] developed in previously irradiated area (24 T1, 8 T2, 6 T3). Most of these lesions were ulcerated or infiltrating (79%). Treatment of PT associated external beam irradiation (mean dose: 52 Gy) and interstitial BT (15 to 25 Gy) with the plastic tube technique (1 to 4 radio - active wires). Lymphatic areas have been treated by exclusive irradiation, radical neck dissection and irradiation, or with irradiation followed by lymphadenectomy. SPT have been treated with BT alone (50 to 75 Gy; 25 case) or with external beam irradiation (30 to 50 Gy) and BT (15 to 40 Gy; 13 cases). No treatment has been performed for lymphatic areas (all patients NO). Results: Local control rate is similar for PT (84%) and for SPT (76%): 90 and 89% respectively for tonsillar tumors, 80 and 73% for palatin arch and 83 and 80% for glosso-tonsillar sulcus. The rate of grade 2 and 3 delayed toxicity is 10% for PT and 14% for SPT. The 3 years survival rates are respectively 71% for primary tumors and 46% for second primaries. Discussion: when compared with external beam RT, BT allows a local control rate increase of 10 to 25% with low complication rates. Salvage surgery morbidity is not increased and salivary function is partially preserved with improvement of quality of life

Tumores testiculares bilaterais por hiperplasia congênita de restos adrenais Bilateral testicular tumors caused by congenital adrenal rest hyperplasia  

Directory of Open Access Journals (Sweden)

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.

He had been treated three years previously for a penetrating injury to that eye. The cyst was treated by aspiration, viscodissection and ab-externo photocoagulation, with this achieving a rapid recovery of vision and good anatomic results. At the six month follow-up visit the visual acuity remains stable with no signs of recurrence of the cyst. Discussion: Conservative surgical treatment consisting of aspiration, viscodissection and photocoagulation appears to be an effective strategy to manage secondary anterior chamber cysts, achieving good anatomic and functional results.

Synchronous thyroid and colon metastases from epidermoid carcinoma of the lung: case report / Metástases sincrônicas de carcinoma epidermoide de pulmão em tireoide e cólon: relato de caso  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese CONTEXTO: O câncer de pulmão de células não pequenas evolui, na maioria dos casos, com metástases a distância. Ossos, sistema nervoso central, glândula adrenal e fígado são os sítios mais frequentes de metástases. Disseminação para pele, miocárdio, tireoide e intestino pode ocorrer, entretanto é rar [...] a. 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. Embora ricamente vascularizada, a tireoide é sítio infrequente de metástases. Os sítios refletem prognósticos reservados na evolução clínica. Não encontramos, na literatura, relato prévio de câncer de pulmão com metástases em cólon e tireoide concomitantes em um único paciente. Abstract in english CONTEXT: Non-small cell lung cancer (NSCLC) progresses to distant metastases in most cases. The most frequent sites for distant metastases are the bones, central nervous system, adrenal glands and liver. 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.

Diagnosis and staging of testicular cancer  

International Nuclear Information System (INIS)

With an incidence of just 2 % of all maligne tumour diseases testicular cancer is a relative rare tumour disease. In comparison to other tumours, orchiectomy is performed as a first step therapy straight after primary staging which is performed by palpation, ultrasonography and evaluation of the tumour markers. In a second diagnostic step initial staging will be done by re-evaluation of the tumour markers, X-ray of the thorax in some cases also by CT, CT of the abdomen/pelvis or MRI of the abdomen, in progressive disease additional MRI of the head. Follow-up after curative therapy will be performed according to the histological type (seminoma - non-seminoma) and tumour staging. (orig.)

Radiation therapy of testicular non-seminomas  

Energy Technology Data Exchange (ETDEWEB)

The prognosis of 121 patients with a non-seminoma testicular tumor MTI or MTU was assessed. The clinical lymph node involvement and the T-category of the primary had a significant bearing on prognosis, which is completely determined by pulmonary relapse. The low-risk group (9% pulmonary relapse, all curable) is characterized by a primary category T/sub 1/ or T/sub 2/ with negative lymphangiography. The percentage of favorable patients is significantly higher if there is malignant teratoma intermediate (MTI) rather than malignant teratoma undifferentiated (MTU) histology. Systematic use of tumor markers (..beta../sub 1/-HCG and alpha fetoprotein), and perhaps an assessment of vascular invasion in the primary, might be useful to identify those patients in the unfavorable group who might benefit from elective chemotherapy.

Ontogenesis of testicular function in humans.  

Directory of Open Access Journals (Sweden)

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.

ABSCESSO TESTICULAR EM HAMSTER: RELATO DE CASO  

Directory of Open Access Journals (Sweden)

Full Text Available The Hamster, rodent originating from the Middle East, is a species studied along with other laboratory animals as experimental models in scientific papers and currently is also created as a pet, by virtue of being docile, easy to handle and require little space for survival. The suppurative processes in domestic animals are relatively frequent. Due to infectious diseases or purulent course of aggressiveness of the environment in which they live. The habit of storing food in the cheeks with sharp edges can injure the skin and often cause abscesses in this species. However, other lesions may lead to suppuration, diseases such as testicular tumor or no tumor or not produced by damage in the skin, leading to tumescence (VITAL et al., 2007. This article reports a case of a hamster treated at the Veterinary Hospital of FAFRAM with clinical history of discomfort, anorexia and frequent licking of the scrotum. On clinical examination it was found by aspiration of purulent secretions and the presence of large numbers of polymorphonuclear cells on cytology, diagnosed with testicular abscess. The animal was taken to the operating room where was performed conventional bilateral orchiectomy and total excision of the abscess by opening the tunica vaginalis and ligation of the spermatic cord. Postoperative care included antibiotic therapy with enrofloxacin and use of an anti-inflammatory meloxicam. After ten days the stitches were removed, the wound was healing satisfactorily and the animal was in good health.O Hamster, roedor originário do Oriente Médio, é uma espécie estudada juntamente com outros animais de laboratório como modelo experimental em trabalhos científicos e, atualmente, também é criado como animal de companhia, em virtude de ser dócil, de fácil manuseio e necessitar de pequeno espaço para sobrevivência. Os processos supurativos nos animais domésticos são relativamente frequentes. Em decorrência de doenças infectocontagiosas de curso purulento ou da agressividade do meio em que vivem. No hamster, o hábito de armazenar alimentos com extremidades pontiagudas nas bochechas, pode lesionar a pele e comumente causar abscessos nesta espécie. No entanto, outras lesões podem levar à supuração, tais como afecções testiculares tumorais ou não tumorais produzidas ou não por lesão de continuidade da pele, levando à intumescência (VITAL et al., 2007. Este trabalho relata um caso de um hamster atendido no Hospital Veterinário da FAFRAM com histórico clínico de inquietação, anorexia e lambedura frequente da região escrotal. Ao exame clínico constatou-se através de punção aspirativa secreção de aspecto purulento e presença de grande quantidade de polimorfonucleares à citologia, sendo diagnosticado abscesso testicular. O animal foi encaminhado para o centro cirúrgico onde foi realizado orquiectomia bilateral convencional e exérese total do abscesso, através de abertura da túcnica vaginal e ligadura do funículo espermático. O pós-operatório incluiu antibioticoterapia com enrofloxacina e utilização de um antiinflamatório meloxican. Após dez dias os pontos foram removidos, a cicatrização da ferida cirúrgica ocorreu de maneira satisfatória e o animal apresentava-se em bom estado de saúde.

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

Science.gov (United States)

Testicular arteries arise from the abdominal aorta and the inferior suprarenal artery from the renal artery. There are reports about variant origin and course of these arteries. Accessory testicular artery is also a common finding but its providing origin to inferior suprarenal artery is an important observation. During a routine dissection of abdomen of approximately 55-year-old male cadaver, unique vascular abnormality was observed. On the left side, a common arterial trunk originating from abdominal aorta immediately branched to give rise to superior testicular and inferior suprarenal arteries, the former after a short course hooked by the left suprarenal vein. In addition, the left suprarenal vein, second left lumbar vein, and left testicular vein joined to form a common trunk which drained into the left renal vein. A sound knowledge of vascular variations in relation to the kidney and suprarenal gland is important to surgeons dissecting the abdominal cavity. PMID:22454832

Transverse testicular ectopia, a case report and review of literature  

Directory of Open Access Journals (Sweden)

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.

A study of topoisomerase activity in human testicular cancers.  

Science.gov (United States)

Topoisomerases are widely detected in rapidly proliferating cancer cells. Many anti-topoisomerase agents are utilized for cancer chemotherapy. Testicular cancers are highly chemotherapy sensitive, however, 10% of them are refractory to the standard regimen. To investigate the topoisomerase activities in human testicular neoplasms, we examined the activity of topoisomerase I (TopoI) and topoisomerase II (TopoII) in 29 testicular tumors. TopoI activity was observed irrespective of pathological types of the tumor (21/29). TopoII was detected in seminoma and teratocarcinoma (5/29). In our experience, seminoma was relatively sensitive to chemotherapy including anti-TopoII agents. Our results suggest that Topol inhibitors could be more effective against seminoma as well as the other types of testicular tumors. PMID:8572612
