Quiste epidermoide testicular / Testicular epidermoid cyst  

Scientific Electronic Library Online (English)

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

Concomitant bilateral testicular epidermoid cysts  

International Nuclear Information System (INIS)

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

Testis-sparing surgery in testicular mass: Testicular epidermoid cysts  

Science.gov (United States)

We present 3 patients with testicular epidermoid cysts who experienced testis-sparing surgery. These patients had a palpable painless testicular mass and underwent inguinal testicular exploration. Intraoperative frozen section revealed no evidence of malignancy and therefore enucleation of the tumour was performed. We demonstrate that careful intraoperative frozen-section examination helps to avoid unnecessary orchidectomy in testicular epidermoid cysts. PMID:24554971

Quiste epidermoide supraselar con rotura intraventricular: caso clínico / Suprasellar epidermoid cyst with intraventricular rupture: case report  

Scientific Electronic Library Online (English)

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

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

Epidermoid cyst is generally regarded as congenital disease, and commonly related to other congenital spinal anomalies. However, it also develops iatrogenically. We report one rare case of epidermoid cyst that we experineced among intradural extramedullary tumors. A 21-year-old female patient was admitted to the hospital due to low back pain with radiating pain into a right lower extremity that initiated about a month ago. She complained sensory lose and motor weakness (grade 4+) on her right extremity as well as urinary dysfunction and sphincter dysfunction. She had a lumbar puncture three times due to Pneumococcal meningitis when she was 13 years old. The well-circumscribed intradural extramedullary mass of 1.8×1.6×4 cm size was found on the L4-5 in a magnetic resonance image. Gross total tumor removal was garried out after the total laminectomy L5 and partial laminectomy L4. The tumor mass was gray-colored and so fragile that it was easy to be removed. The histological diagnosis confirmed epidermoid cyst without malignancy. After the operation, the patient progressively showed remarkable neurological recovery. In this case, the cause of epidermoid cyst is considered iatrogenic concerning history of several times of lumbar puncture as meningitis. PMID:25346768

Ultrasonographic findings of testicular tumors: Correlation with pathologic findings  

International Nuclear Information System (INIS)

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

Intradiploic epidermoid cysts  

International Nuclear Information System (INIS)

We studied 37 intradiploic epidermoid cysts, reviewing typical and atypical radiological features and the differential diagnosis. The most common clinical feature was a long standing lump in the scalp, occurring in 25 patients (67.7 %). Plain films were the most cost-effective radiological technique in diagnosis. The typical finding was a well-defined lytic lesion with sclerotic border, seen in 29 cases (78 %). Atypical lesions were those larger than 5 cm and/or with an ill-defined edge, being observed in 8 cases (22 %). CT and MRI were the best methods for assessing atypical ones. In all cases with typical radiological findings a preoperative diagnosis of intradiploic epidermoid cyst was suggested. (orig.). With 8 figs., 3 tabs

An epidermoid cyst of the cecum is extremely rare; only eight cases have been reported in the literature. A 63-year-old woman was admitted to Kyung Hee University Medical Center with a colonic mass that had been discovered incidentally during a regular health check-up. The radiographic impression was that this mass was a gastrointestinal stromal tumor. During surgery, an exophytic mass in the cecal wall was resected by using an ileocecectomy. Based on the macroscopic and the microscopic findings, this case was identified as an epidermoid cyst of the cecal wall. We report this case to discuss the origin of this entity and the unusual nature of our case. PMID:25745626

Estudio de la fertilidad y viabilidad de quistes hidatídicos ovinos  

Directory of Open Access Journals (Sweden)

Full Text Available FUNDAMENTO: La finalidad de este trabajo es analizar la fertilidad de los quistes hidatídicos de origen ovino, especie de gran interés epidemiológico en la hidatidosis, y la adecuación del gerbillo (Meriones unguiculatus como modelo experimental para el estudio "in vivo" de dicha hidatidosis, fase preliminar de posteriores estudios terapeúticos. MÉTODOS: Se ha realizado un estudio de la fertilidad y viabilidad de quistes hidatídicos procedentes de pulmones e hígados de ganado ovino de Castilla y León a través del examen y evaluación de una serie de parámetros entre los que figura la producción de una hidatidosis secundaria experimental en animales de laboratorio. RESULTADOS: El índice quístico total obtenido fue de 8,57 quistes por ovino infestado (5,97 quistes por pulmón infestado y 5,57 quistes por hígado infestado. El porcentaje de fertilidad obtenido en los quistes hidatídicos de origen ovino que contenían protoescólex viables "in vitro" fue del 43,97% (43,02% en los quistes pulmonares y 46,16% en los quistes hepáticos. La viabilidad "in vivo" de los protoescólex seleccionados se puso de manifiesto al producirse en el 100% de los gerbillos infectados una hidatidosis secundaria experimental. CONCLUSIONES: Se destaca la validez de los criterios utilizados para estudiar la viabilidad "in vitro" de los protoescólex procedentes de quistes hidatídicos de origen ovino. La hidatidosis secundaria producida en gerbillos nos conduce a considerarlos como especie de experimentación adecuada para la investigación "in vivo" de la hidatidosis de origen ovino.

Se hace referencia además a la posibilidad que brindó el acceso por cirugía laparoscópica de realizar procedimientos asociados en un mismo paciente: colecistectomía y exéresis del quiste de ovario errante. Abstract in english The case of a female patient aged 52 is presented, admitted in the National Endoscopy Surgery Center due to a persistent pain and heaviness sensation in the lower stomach as well as dyspeptic disorders. After laboratory and imaging studies a cyst in right ovary of 5-8 mm diameter (echolucid), necrot [...] ic and adhered to mesocolon was diagnosed. A exeresis and a cholecystectomy were performed. Due to its infrequent location of a ovarian cyst the clinical features and the surgical and anatomical and pathological results are presented to national and international scientific community. Authors also make reference to the possibility allowed by the laparoscopic surgery approach to carry out procedures associated in a same patient: cholecystectomy and exeresis of erratic ovarian cyst.

MR imaging of epidermoid cysts  

International Nuclear Information System (INIS)

After a review of literature, MRI assessments of four cases of epidermoid cysts (E.C.) are reported. E.C., (characterized in computed tomography by hypo or iso-density areas non enhanced by contrast), are characterized in MRI by: 1) an important variability of signal intensity between the different cases, and sometimes between the differents parts of the same cyst, 2) the absence of edema in surrounding parenchyma, in spite of important mass effect, 3) well defined limits, permitting certainty of the extra-cerebral nature of this tumor, 4) the presence of calcifications earyl perceptible in MRI. It is proposed that the variability of signal intensity of E.C. is caused by different relaxation time values corresponding to different concentrations of keratin, cholesterol and water content.

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.

Testicular varicoceles  

Energy Technology Data Exchange (ETDEWEB)

A testicular varicocele represents an abnormal degree of venous dilatation of the pampiniform plexus. It is a relatively common condition and may present at scrotal pain and swelling. An association with male subfertility is an area of debate. This article describes the present day radiological criteria and imaging techniques to aid accurate diagnosis of varicoceles. In addition, the role of the interventional radiologist in treating this condition is discussed.

Testicular tumors  

International Nuclear Information System (INIS)

The decision to perform CT or lymphangiography should be based upon the anticipated method of treatment. In some cases, ultrasonography may be an acceptable alternative primary abdominal imaging method. In addition, ultrasonography may play an important role in the detection of occult testicular neoplasms in patients who have metastatic disease and a normal scrotal examination. Intravenous urography and inferior vena cavography are insensitive methods for the detection of retroperitoneal lymphadenopathy and need not be used routinely for staging. Because the lungs are the major extralymphatic site of metastases in patients with testicular neoplasms some form of chest imaging should be performed in all patients. In this regard, CT has proved more sensitive than full chest tomography for the detection of both pulmonary and mediastinal metastases. Radioimmunoassays for serum alpha-fetoprotein (AFP) and the beta subunit of human chorionic gonadotropin (beta-HCG), although they fall outside the domain of radiology, are discussed because of their importance in the clinical staging and management of testicular tumors

[Interhemispheric epidermoid cyst. A clinical case].  

Science.gov (United States)

The authors report a rare case of epidermoid cyst with interhemispheric growth closely connected to the anterior portion of the corpus callosum. Although extremely sensitive in determining the site, dimensions and relations of the lesion, NMR does not allow the nature of this pathology to be diagnosed owing to the lack of signal specificity. CT, using the measurement of Hounsfield units, allows a differential diagnosis of epidermoid cysts and arachnoid cysts and lipomas to be made in almost all cases. Treatment is surgical and the complete excision of the capsule avoids recidivation. PMID:8622812

Atypical intracranial epidermoid cysts: rare anomalies with unique radiological features.  

Science.gov (United States)

Epidermoid cysts are benign slow growing extra-axial tumours that insinuate between brain structures, while their occurrences in intra-axial or intradiploic locations are exceptionally rare. We present the clinical, imaging, and pathological findings in two patients with atypical epidermoid cysts. CT and MRI findings for the first case revealed an intraparenchymal epidermoid cyst that demonstrated no restricted diffusion. The second case demonstrated an aggressive epidermoid cyst that invaded into the intradiploic spaces, transverse sinus, and the calvarium. The timing of ectodermal tissue sequestration during fetal development may account for the occurrence of atypical epidermoid cysts. PMID:25667778

Tratamiento laparoscópico de los Quistes hidatidicos hepáticos  

Scientific Electronic Library Online (English)

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

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

Giant epidermoid cyst of the posterior neck.  

Science.gov (United States)

A 49-year-old man was presented for evaluation of a painless mass on his right posterior neck. The mass had gradually enlarged for a 25-year period without inflammation or rupture. On physical examination, a round, nontender, soft-tissue mass, 8 cm in diameter, was noted on the right posterior neck. The neck is a common site of epidermoid cysts, but a mass more than 5 cm in diameter is rare. A contrast-enhanced neck computed tomographic (CT) scan revealed a 7.6 × 6.5 × 5.7 cm unilocular hypodense mass adjacent to the posterior neck muscles.The mass was completely excised under general anesthesia. A histopathologic examination of the excised specimen resulted in a diagnosis of an epidermoid cyst. The patient was discharged from the hospital on the third postoperative day. There were no recurrences in a 2-year follow-up period. PMID:21586972

Sublingual epidermoid cyst: a case report  

Directory of Open Access Journals (Sweden)

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

Giant intracranial epidermoids: is total removal feasible?  

Science.gov (United States)

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

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.

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 coulthe inflammatory granulomatous tissue could explain its density on the CT scan.

Carcinoma epidermoide primario do estomago Primary epidermoid carcinoma of the stomach  

Directory of Open Access Journals (Sweden)

Full Text Available Os AA. chamam a attenção para a raridade deste typo histologico de tumor do estomago e descrevem um caso verificado pela autopsia, em individuo branco, brasileiro, de 67 annos de edade. O tumor localiza-se na pequena curvatura do estomago, sob o aspecto de uma formação crateriforme de 3,5 cms. de diametro e com adherencias ao pancreas. O esophago e o cardia não são de modo algum comprometidos pelo processo. Foram encontradas metastases no coração, no figado, na capsula do pancrea, no pulmão e glandulas suprarenaes. O exame histologico mostra tratar-se de um carcinoma epidermoide, não só no tumor primitivo, como tambem nos fócos metastaticos. As AA. são inclinados a acreditar que o tumor tenha se originado por intermedio de um processo d metaplasia epidermoide da mucosa gastrica.Attention is called by the AA. to the rarity of this histological feature of gastric tumor verified and described, on post mortem examination, in a white Brazilian male, 57 years old. The tumor is located on the lesser curvature of the stomach under the appearance of a crateriform formation, 3.5 cms. in diameter, fast adhering to the pancreas. The esophagus and cardia are not affected by this process. Metastases were found in the heart, liver, capsule of the pancreas, lungs and adrenal glands. The histological examination reveals in te primary tumor and in the metastatic foci a carcinoma of epidermoid type. The AA. are inclined to believe that the tumor might have arisen through an epidermoid-metaplastic process of the gastric mucosa.

The authors describe a case of epidermoid cyst in the posterior fossa causing hydrocephalus and review morphologic and diagnostic criteria of this lesion.

Quistes epididimarios en la infancia / Epididymal cysts in childhood  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish OBJETIVO: Hemos realizado una revisión retrospectiva de los casos atendidos en los últimos 5 años; se han recogido un total de 15 casos. Los quistes simples de epidídimo son patología poco frecuente en la infancia diagnosticándose la mayoría en la pubertad. Actualmente y debido a la escasa casuístic [...] a no existe consenso en la terapéutica más adecuada. METODOS/RESULTADOS: La edad media de presentación fue de 11,5 años (1-16). El 50% fueron diagnosticados de forma incidental y un 29% cursó con aumento de tamaño escrotal. El 46% de los casos presentaban varicocele izquierdo asociado (n=6) y un 26% presentaba antecedentes de orquiepididimitis. El diagnóstico se basó en la exploración física con confirmación ecográfica. Un 40 % fue tratado quirúrgicamente y el resto fue subsidiario de tratamiento conservador sin constatarse la presencia de complicaciones en estos en los controles posteriores. CONCLUSIONES: Dada la benignidad y la buena evolución de todos los casos de quistes de epidídimo tratados de forma conservadora, y la ausencia de beneficio con el tratamiento quirúrgico, creemos que el tratamiento debe ser conservador con controles clínicos y ecográficos reservando el tratamiento quirúrgico para aquellos quistes que presenten complicaciones. La frecuente asociación encontrada entre el quiste epididimario y el varicocele responde a una coincidencia de ambas patologías en la edad peripuberal. Abstract in english OBJECTIVES: To retrospectively review all cases of epididymal cysts registered over the last five years; 15 cases have been included. Simple epididymal cysts are a rare pathology in childhood, being most of them diagnosed in puberty. Currently, due to the scarce case series, there is not consensus a [...] bout the most adequate therapy. METHODS/RESULTS: Mean age at presentation was 11.5 yr. (1-16). 50% were diagnosed incidentally and 29% presented increased scrotal size. 46% of the cases had associated left varicocele (n = 6) and 26% had history of orchiepididymitis. Diagnosis was based on physical examination and confirmed by ultrasound. 40% of the patients underwent surgery and the remainder received conservative treatment without evidence of complications on follow-up. CONCLUSIONS: Due to the benign character and good evolution of all cases of epididymal cysts treated conservatively and the absence of benefit after surgical treatment, we believe that management should be conservative with clinical and ultrasound controls, leaving surgery for cysts with complications. The frequent association between epididymal cysts and varicocele is related to coincidence of both pathologies in the prepuberal age.

Science.gov (United States)

The authors present a case of epidermoid splenic cyst in masculine patient of 13 years, that presented decrease of appetite, fever and alimentary vomits and tangible abdominal mass in the physical exam. Abdominal ultrasonography demonstrated expansible lesion in the topography of the spleen, and computerized tomography revealed intrinsic homogeneous lesion of the spleen, without communication with pancreas. To the laparotomy, cystic mass of great extension was observed, submitted total esplenectomy, being diagnosed in the histopatological exam epidermoid splenic cystic. In the follow-up patient developed with disappearance of the symptoms. The epidermoid splenic cyst are rare, they can be seen mainly in children and young adults, what proposes a congenital origin for this disease. PMID:10962631

Hemorrhagic epidermoid cyst in a patient with generalized tonic clonic seizure.  

Science.gov (United States)

Epidermoid cysts account for approximately 1% of all intracranial tumors. Hemorrhage into an epidermoid cyst is extremely rare, and has only been reported a few times. To our knowledge, there are no reports of a hemorrhagic epidermoid cyst presenting with a first generalized tonic clonic seizure. We present a 68-year old female with an epidermoid cyst with intracystic hemorrhage who presented with a first time generalized tonic clonic seizure. When complicated with hemorrhage, the diagnosis of an epidermoid cyst is challenging and there is a potential for misdiagnosis. PMID:23352350

Intraosseous epidermoid cysts in the distal phalanx of two dogs  

International Nuclear Information System (INIS)

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

Studies of testicular function after treatment for testicular tumor, 1  

International Nuclear Information System (INIS)

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

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...

Testicular Volume: Size Does Matter  

International Nuclear Information System (INIS)

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

Epidermoid carcinoma of the skin mimicking breast cancer.  

Science.gov (United States)

Nonmelanoma skin cancer is the most frequent cancer in the world. Squamous cell cancer often occurs in sun-exposed areas, such as the head and neck. When it involves the breast and ulce-rates, invading the glandular parenchyma, it may mimic breast cancer. Confirmation by means of histopathological examination, combined with clinical examination, is a critical instrument for the accuracy of the diagnosis. We report a case of an epidermoid carcinoma located on the breast skin, initially diagnosed as breast cancer. PMID:23739713

Apresentamos um caso de ectopia cruzada do testículo direito, tratado por transposição extraperitoneal da gônada e orquipexia direita. CONCLUSÃO: Os conhec [...] imentos embriológicos e os achados cirúrgicos sugerem que a ETC seja uma conseqüência comum de vários fatores etiológicos, sobretudo fatores mecânicos, e pode causar persistência do ducto de Müller. Após extensa revisão da literatura,sugerimos uma classificação da ETC em 3 tipos: 1 - associada somente à hérnia inguinal; II associada a remanescentes mullerianos; III - associada a outras anomalias, sem remanescentes mullerianos. O tratamento inclui orquipexia trans-septal ou transposição trans-abdominal do testículo, pesquisa de remanescentes mullerianos e outras anomalias, e seguimento pós-operatório a longo prazo, devido a risco de malignização. Abstract in english Crossed testicular ectopia (CTE) is a rare anomaly, characterized by migration of one testis towards the opposite inguinal canal. Presented here is a case of crossed ectopia of the right testis, treated by extraperitoneal transposition of the gonad and right orchiopexy. Embriology and surgical findi [...] ngs suggest that CTE is a common consequence of many unclear ethiologic factors, specially mechanical ones, and can be associated with Muller duct persistence. Review of literature suggests a classification of CTE into 3 types: I - associated with inguinal hernia alone; II - associated with persistent mullerian remnants; III - associated with other anomalies without mullerian remnants. Treatment includes transeptal orchiopexy or extraperitoneal transposition of the testis, research for mullerian remnants and other anomalies, and long term postoperative follow-up, due to the risk of becoming malignant.

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

Neonatal Testicular Torsion; A Review Article  

Directory of Open Access Journals (Sweden)

Full Text Available Neonatal testicular torsion, also known as perinatal testicular torsion is a subject of debate among surgeons. Neonatal testicular torsion either intrauterine or postnatal results into extravaginal torsion which is a different entity than intravaginal type but has the same devastating consequences if not diagnosed and managed well in time. Testicular torsion results into acute ischemia with its resultant sequaele such as abnormality of testicular function and fertility. Urgent surgical exploration and fixation of the other testis are the key points in the management. General anesthesia is not a contraindication for exploration as thought before. Diagnosis and controversies on management of testicular torsion are discussed in this review.

Epidermoid cyst in an intrapancreatic accessory spleen: a case report.  

Science.gov (United States)

Ectopic splenic tissue in the abdominal cavity is a common entity, with a reported incidence of 10% in the general population. However, an intrapancreatic accessory spleen is a rare disease, and moreover cyst formation in it is exceedingly rare. A 58-year-old woman with a 25-mm multilocular cyst in the tail of the pancreas detected incidentally by ultrasonography was admitted for further evaluation. Because malignancy could not be ruled out, a spleen-preserving distal pancreatectomy was performed. The cut surface of the surgical specimen showed a multilocular cyst surrounded by brown solid tissue resembling normal spleen. Pathological examination revealed it was stratified squamous epithelium and was surrounded by splenic tissue. The final pathological diagnosis was epidermoid cyst in an accessory spleen in the pancreas. This cyst has no characteristic features on diagnostic imaging. Consequently, it is not possible to make a definite preoperative diagnosis in most cases. Epidermoid cyst in intrapancreatic splenic tissue is another lesion to be considered in the differential diagnosis of pancreatic tail tumors. PMID:15754048

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.

Testicular teratoma, mimicking a simple testicular cyst, in an infant.  

Science.gov (United States)

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

[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.

Epidermoid carcinoma involving the parotid gland and orbital region: case report of a rare entity.  

Science.gov (United States)

Epidermoid carcinoma (also known as squamous cell carcinoma) of the parotid gland is more prevalent among the elderly, as are other head and neck tumors. In most cases it is observed either as a nodal metastasis of a primary tumor that drains into the parotid area or as a direct extension of a tumor that has originated in the upper dermis. Primary epidermoid carcinomas arising directly from the parotid gland are extremely rare. Similarly, secondary invasion of the orbital region by a neighboring tumor is more common than primary epidermoid carcinoma of the orbit, which is also rare. In this article, we discuss the diagnosis and treatment of a rare case of epidermoid carcinoma simultaneously invading the parotid gland and the orbit. PMID:18633934

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.

Retrorectal epidermoid cyst with unusually elevated serum SCC level, initially diagnosed as an ovarian tumor  

Directory of Open Access Journals (Sweden)

Full Text Available Retrorectal epidermoid cyst is one of the developmental cysts which arise from remnants of embryonic tissues. We report a rare case of retrorectal epidermoid cyst, initially diagnosed as an ovarian tumor. Serum SCC value as tumor marker was elevated to the high level. Laparoscopy revealed ovaries, uterus and other pelvic organs were all normal. This tumor existed in the retroperitoneal cavity and compressed the rectum. Later, complete tumor resection was performed by laparotomy. Histological study revealed the epithelium of this tumor consisted of only squamous cells without atypia, and the diagnosis of this tumor was retrorectal epidermoid cyst. Retrorectal epidermoid cyst is very rare, and difficult to diagnose before surgery. However, if we haveknowledge of developmental cysts, and by careful digital examination and image diagnosis, a differential diagnosis can be made.

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 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.

An epidermoid cyst is formed when there is proliferation of epidermal cells within an area of the dermis. They may be formed by the traumatic implantation of epidermal cells within the dermis as well as many other mechanisms. We present a case of epidermoid cyst formation following Topaz coblation for plantar fasciitis; a complication we believe is yet to be reported in the literature. PMID:22265448

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

International Nuclear Information System (INIS)

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.)

Quiste residual gigante: presentación de un caso / Residual cyst: a case presentation  

Scientific Electronic Library Online (English)

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

Association between testicular microlithiasis, testicular cancer, cryptorchidism and history of ascending testis  

Scientific Electronic Library Online (English)

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

La et [...] iología, es inflamatoria ya que existe una progresión del proceso inflamatorio de los molares temporales tratados endodónticamente hacia el folículo del premolar. El tratamiento de ésta patología varía desde la extracción del diente temporal hasta un tratamiento más invasivo como la enucleación del quiste. La selección del tratamiento depende de diferentes factores como la edad del paciente, tamaño de la lesión, compromiso de estructuras adyacentes, ubicación del diente retenido etc. Generalmente el pronóstico es bueno. Se presenta una revisión de la literatura sobre el quiste folicular inflamatorio, y tres casos pediátricos. Se revisarán las características clínicas, imagenológicas, posibles diagnósticos diferenciales y el tratamiento Abstract in english The follicular cyst was classified by the OMS in 1992 as an inflammatory cyst. The prevalence is poor and may be encountered in patients between 5 and 12 years old. There is a male predilection and a higher prevalence in the mandibular premolars The pathogenesis is a result of the progression from a [...] periapical inflammation from an overlying primary tooth that has been pulpotomized to the premolar follicle. The treatment for the follicular cyst varies from the extraction of the primary tooth to enucleation of the cyst. The selection of the treatment depends on the age of the patient, extension of the cyst, the compromise of the adjacent structures, location of the impacted tooth etc. Generally the prognosis is excellent. A review of the literature about the follicular cyst and three pediatric cases will be presented. The clinical and radiographic features, differential diagnosis and treatment will be discussed

Referida para colangiopancreatografía retrograda endoscópica, estudio que fue omitido por ecosonograma abdominal control sugestivo de Quiste de colédoco. Se solicita nueva colangioresonancia, que no visualiza quiste y reporta dilatación de hepatocoledoco y colédoco terminal de aspecto afinado. Se mantiene conducta expectante. La paciente permanece asintomática, con reevaluación 3 meses después. El ecosonograma abdominal revelo: dilatación fusiforme del colédoco en toda su extensión, hallazgo compatible con quiste de colédoco tipo I. Se realiza resección del quiste, con buena evolución clínica. Se concluye que el uso de estudios por imágenes no invasivos son de utilidad en la evaluación hepatobiliar en niños, y el ultrasonido abdominal continua como método de elección para esta patología. Abstract in english Choledochal cyst is a congenital malformation of the bile ducts rare, usually seen in childhood. The classic triad of jaundice, abdominal mass and pain is not always present.

Referred for endoscopic retrograde cholangiopancreatography, a study that was omitted from control abdominal ultrasound suggestive of choledochal cyst. New requested from magnetic resonance, which displayed no reports cyst and bile duct dilation and terminal hepatocoledoco related aspects. Expectant management is maintained. 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.

MANEJO LAPAROSCÓPICO DE QUISTES OVÁRICOS COMPLICADOS O PERSISTENTES DURANTE EL EMBARAZO  

Scientific Electronic Library Online (English)

Full Text Available Antecedentes: El incremento en el hallazgo de quistes anexiales durante el embarazo sería el mayor uso de técnicas de reproducción asistida con hiperestimulación ovárica controlada. La complicación más frecuente sigue siendo la torsión anexial. Objetivo: Revisar el manejo de quistes anexiales compli [...] cados o persistentes, durante el embarazo, con resolución laparoscópica. Método: Revisión retrospectiva de 9 pacientes consecutivas, ingresadas al Departamento de Obstetricia y Ginecología Clínica Las Condes. Resultados: La edad gestacional de ingreso fue entre 5+5 y 27 semanas. Cinco casos fueron producto de fertilización asistida y cuatro espontáneos. Ocho (85,6%) embarazadas, ingresaron por dolor abdominal agudo. Otro caso ingresó a cirugía electiva por quiste ovárico persistente. Los quistes tenían entre 6 y 13 cm. En 5 se realizó sólo destorsión ovárica, en 1 ooforectomía y en 1 quistectomía. Se realizó punción, destorsión y fijación a ligamento útero ovárico, bilateral, en la otra paciente. Se registró un caso de fiebre en el postoperatorio. El alta hospitalaria fue a las 48 horas en 6 (67%), a las 72 en 2 y a las 96 en 1. El estudio biópsico diferido en 3 pacientes demostró: 1 quiste seroso paratubario, 1 quiste luteínico parcialmente hemorrágico y 1 infarto anexial. Todos los embarazos evolucionaron normalmente. Conclusión: Nuestra experiencia confirma que en el embarazo la laparoscopía es una buena opción al requerir una cirugía por quiste anexial complicado o persistente.

Method: Retrospective review of 9 consecutive patients, admitted at the Department of Obstetrics and Gynecology, Clínica Las Condes. Results: The gestational age was between 5+5 and 27 weeks. Five were the product of assisted fertilization and four spontaneous. Eight (85.6%) pregnant women were admitted by emergency room because of acute abdominal pain and another one went through elective surgery for persistent ovarian cyst. Preoperative diagnosis of the 8 patients admitted by emergency: adnexal cyst complicated with torsion in 6 (1 adnexal infarction) and 2 cases of acute abdomen. The cysts were between 6 and 13 cm. Type of surgery: in 5, only detorsión; ovarian oophorectomy in 1 and cystectomy in one. Puncture, detorsión and bilateral fixation of uterine ovarian ligament, in another patient. One case required conversion to laparotomy with adnexectomy. Postoperative fever was observed in one patient. Discharge was at 48 hrs in 6 (67%) cases, at 72 hrs. in 2 and 96 hrs. in 1. Deferred biopsy performed in 3 patients showed: paratu-barian serous cyst, partially hemorrhagic luteal cyst, adnexal infarction. All pregnancies went on normally. Premature births are not reported. Conclusion: Our experience suggests that laparoscopic approach is a valid option for complicated or persistent adnexal cysts in pregnant women.

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

Intracranial germinoma in the pineal region arising after subtotal resection of epidermoid cyst: case report.  

Science.gov (United States)

We present an unusual case of a germinoma of the pineal region arising adjacent to an epidermoid cyst in a 16-year-old male. Initial imaging findings were classic for epidermoid cyst. The patient underwent two partial resections at an outside institution, each specimen demonstrating pure epidermoid cyst. Follow-up imaging over a period of 24 months showed an area of progressive contrast enhancement adjacent to the initial lesion, suggesting the development of a neoplasm. Given the area of contrast enhancement in addition to worsening headaches and visual changes, he underwent a third and final resection at our institution. Pathology revealed a mixed germ cell tumor with prominent germinoma component in addition to a well-differentiated epidermoid cyst. Details of his imaging and pathologic findings are presented, and possible explanations for these findings are explored, the most likely of which is lack of complete resection at the onset failed to identify the whole of the neoplasm. We conclude that pediatric epidermoid cysts of the pineal region should always receive close follow-up, particularly when total resection is not performed. PMID:24221216

Testicular microlithiasis is a rare condition usually diagnosed by scrotal ultrasound and associated with pathology of the testis. We report two pediatric cases presented with acute scrotum. Testicular sonography revealed significant bilateral testicular microlithiasis. One case was diagnosed as having torsion of the right testis and the other case as orchiepididymitis. A careful review of the literature is made and a periodic follow-up of this disease is advocated. PMID:11199303

Testicular torsion in the older patient  

International Nuclear Information System (INIS)

A 40-year-old man presented with severe right-sided scrotal pain and was proven to have a 720-degree right testicular torsion. Fewer than 50 documented cases of testicular torsion have been reported in men over the age of thirty. The anatomical predisposition for torsion generally selects these individuals early in life. Rapid diagnosis allowed for surgical correction and testicular salvage. We outline an expedient diagnostic approach for these difficult cases with use of the Doppler ultrasound and the technetium (99mTc) testicular scan

[Pulmonary metastasis of epidermoid carcinoma of the larynx: a case with an interstitial pattern of growth].  

Science.gov (United States)

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

Quiste dermoide verdadero en piso de boca / True dermoid cyst in the floor of the mouth

Full Text Available SciELO Cuba | Language: Spanish Abstract in spanish Los quistes dermoides son lesiones benignas de origen embrionario, con una incidencia del 0,01 % de todos los quistes de la cavidad bucal. 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.

Testicular thermoregulation in Bos indicus, crossbred and Bos taurus bulls: relationship with scrotal, testicular vascular cone and testicular morphology, and effects on semen quality and sperm production.  

Science.gov (United States)

Mechanisms of testicular thermoregulation, the relationship of scrotal, testicular vascular cone (TVC), and testicular morphology with thermoregulatory capability, and their effects on semen quality and sperm production were studied in 20 Bos indicus, 28 crossbred, and 26 Bos taurus bulls. The ratio of testicular artery length and volume to testicular volume were larger (Psperm production was associated with increased testicular artery volume, testicular volume, and SQT temperature gradient, and with decreased testicular artery wall thickness, scrotal circumference (SC), and scrotal surface, testicular subtunic, and epididymal temperatures. In conclusion, morphology of the TVC may contribute to the greater resistance of B. indicus bulls to high ambient temperatures by conferring a better testicular blood supply and by facilitating heat transfer between the testicular artery and veins. Testicular thermoregulation was associated with opposing scrotal and testicular subtunic temperatures gradients only in crossbred and B. taurus bulls. Scrotal, TVC, and testicular morphology influence testicular thermoregulatory capability and were associated with differences in semen quality and sperm production. PMID:14662148

Clitoral epidermoid cyst secondary to blunt trauma in a 9-year-old child.  

Science.gov (United States)

Epidermoid cysts are slowly growing tumors arising from invagination of the epidermis into the dermis traumatically or spontaneously. This implantation in the clitoris is most commonly induced by female genital mutilation. The reported cases with spontaneous onset of this clitoral lesion are scarce. Trauma other than female circumcision predisposing to the onset of the cyst has not been mentioned before. A nine-year-old girl was presented for swelling in the pubic region with the onset following an accidental trauma; the diagnosis was determined to be epidermoid cyst of the clitoris after a brief preoperative evaluation and an accurate surgical management.

Persistent testicular pain after vasectomy.  

Science.gov (United States)

Following vasectomy, the patient had right testicular pain. The sperm granuloma regressed under antibiotic therapy but another painful nodule followed. Antibiotics and prostatic massage were not helpful. A nerve block alleviated the pain for several hours. A recurring sperm granuloma was diagnosed. Many of these undergo spontaneous resolution. Bed rest and antiinflammatory agents such as Tandearil (oxyphenbutazone) are indicated. Nerves may be incorporated in the vasectomy site by scar tissue or suture material. Other proposed treatment is excision of the vasectomy site. If this is not successful, then an epididymectomy is indicated. PMID:12308660

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% 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.

[Fertility in testicular cancer patients].  

Science.gov (United States)

Testicular cancer(TC)is the most common and curable cancer affectingmen of reproductive age. Successful treatment approaches have resulted in longer life expectancy in TC survivors. The most frequently used treatment for TC is a combination of inguinal orchiectomy, and either radiotherapy or cisplatin-based chemotherapy. In many TC patients, sperm quality is already abnormal and there may even be a lack of viable spermatozoa at the time of diagnosis. Therefore, the effect of cancer treatment on fertility is a potentially significant issue. Fertility preservation in these men has become essential and needs to be discussed prior to the start of cancer treatment. The only currently established fertility preservation method is the cryopreservation of sperm before therapy. For most patients seekingcryopreservation, the semen sample is collected via masturbation. If the patient is unable to ejaculate for any reason, other techniques such as vibratory stimulation and electroejaculation can be performed. In azoospermic or severely oligozoospermic patients, testicular sperm extraction at the time of the inguinal orchiectomy is a useful technique for obtainingspermatozoa before cytotoxic therapy. We herein present an overview of the current topics on fertility in TC patients, includingthe effects of surgery, chemotherapy, and radiation therapy. We also describe the strategy for fertility preservation in these patients. PMID:25812494

Terminal bifurcation of the right testicular vein and left testicular arterio-venous anastomosis.  

Science.gov (United States)

The testis is the organ upon which the survival of the human species depends. Abnormalities of testicular vessels may lead to loss of gametogenesis and hormone production. Reported here is a case of bilateral variations of the testicular vessels observed in a male cadaver during the first year MBBS dissection classes. The right testicular vein bifurcated into two veins just before its termination and both the branches terminated into the inferior vena cava. The left testicular artery arose from the abdominal aorta just above the level of origin of the inferior mesenteric artery. There was an arterio-venous anastomosis between the left testicular vein and the left testicular artery. The arterio-venous anastomosis might be functionally important as it can change the quality of the blood entering the testis. PMID:24096228

To evaluate CISS MR imaging findings of epidermoid tumor in comparison with conventional spin-echo images. We studied 6 cases of epidermoid tumor in the subarachnoid space. We used a 1.5T MR unit to obtain CISS images(TR/TE/FA ; 12.3msec/5.9 msec/700) and T1- and T2- weighted spin-echo images. CISS MR imaging findings were evaluated with respect to tumor's signal intensity , contour, and relation with adjacent structures. Conspicuity of the tumor was compared between CISS and spin-echo images. A quantitative analysis was performed by measuring tumor to CSF contrast. In qualitative analysis, three radiologists independently compared CISS image and conventional spin-echo images for visibility of the tumor and graded them into three categories( poor, good, and excellent). Epidermoid tumors were located in the cerebellopontine angle in 4 cases, the prepontine cisstern in 1 case, and the cerebellopontine angle-prepontine cistern in 1 case. The tumors were hyperintense relative to brain parenchyma and hypointense relative to CSF on CISS images, were lobulated, encased adjacent cranial nerve and vessels, and invaginated into brain parenchyma. In qualitative analysis, CISS images showed clear demarcation between tumor and CSF, exact tumor extension, and tumor's relation with cranial nerves and vessels better than conventional spin-echo images. In quantitative analysis, the mean contrast values of tumor to CSF on T1-, T2-weighted images, and CISS images were 0.12, 0.06, and 0.52, respectively. The contrast value for CISS images was significantly higher than that for T1-and T2-weighted images(p<0.05). Epidermoid tumors in the subarachnoid space are better demonstrated on CISS images than on conventional spin-echo images. This special MR sequence can be added as a routine protocol in the diagnosis of subarachnoid epidermoid tumor.

Carcinoma broncogénico epidermoide en un hombre de 21 años Epidermoid bronchogenic carcinoma in a 21 year old black man  

Directory of Open Access Journals (Sweden)

Full Text Available Hombre de 21 años de edad de raza negra, natural del Chocó (Colombia, quien ha desempeñado diversos oficios; presentó un síndrome de dificultad respiratoria de dos meses de evolución, dolor pleurítico derecho, insuficiencia cardíaca congestiva y síntomas sistémicos. En la necropsia se encontró una masa tumoral blanco-grisácea de 10 x 8 cm, homogénea, con áreas de necrosis, originada en el bronquio principal de los lóbulos inferior y medio derechos y que invadió por vecindad en forma de coraza todo el pericardio causando una pericarditis constrictiva tumoral. El estudio microscópico correspondió a un carcinoma broncogénico tipo epidermoide bien diferenciado. El carcinoma broncogénico se asocia frecuentemente con el consumo de cigarrillo pero su incidencia ha c.umentado entre las personas no fumadoras, lo que sugiere la posibilidad de otros factores que influyen en su presentación como son los contaminantes atmósféricos, la predisposición genética, la dieta deficiente en vitamina A y carotenos, la presencia de ciertos virus y cambios inmunológicos. Este tumor constituye el 16% de todos los cánceres en el hombre y e113% en las mujeres; aparece con mayor frecuencia entre los 40 y los 70 años y sólo del1 al 5% de los casos se presenta en menores de 40 años. A 21 year cid black man, native from Chocó (Colombia, variously employed, who presented with a respiratory difficulty syndrome of two months of evolution, right pleuritic pain, congestive cardiac failure and systemic symptoms. A homogeneic white .grayish tumor measuring 8 by 10 cm with necrotic areas was found at necropsy. The tumor originated in the main bronchial tube of the lower and middle lobes of the right lung and invaded the entire pericardial vicinity forming a cuirass and causing tumoral constrictive pericarditis. Microscopic studies revealed a well differentiated squamous type bronchogenic carcinoma. Bronchogenic carcinomas are frequently associated with cigarette smoking. However, their incidente has increased among non. smokers, suggesting the possibility that there are other causal factors, such as atmospheric contaminants, genetic predisposition, diets deficient in vitamin A and carotene, presente of certain viruses and immunologic changes. Lung cancer constitutes 16% among the types of cancer suffered by men and 13% among women, it has its greatest incidente in groups between 40 and 70 years of age and only 1 to 5 percent of thecasesoccur in groupsunder theageofforty years.

Testicular cancer: addressing the psychosexual issues.  

LENUS (Irish Health Repository)

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

An unusual presentation of testicular tumor  

International Nuclear Information System (INIS)

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

[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

Testicular Involvement of Tuberculous Epididymitis : Sonographic Findings  

International Nuclear Information System (INIS)

To report the sonographic findings of testicular involvement of tuberculous epididymitis. The sonographic findings of testicular involvement in twelve patients with histologically proven tuberculous epididymitis were retrospectively reviewed. The sonographic findings of testicular lesions are 1) an ill defined hypoechoic lesion (3 cases, 25.0%), 2) a well-demarcated hypoechoic lesion (3 cases, 25.0%),3) multiple and small hypoechoic nodules in the enlarged testis (2 cases, 16.7%), 4) indistinct margin between the testis and epididymis (2 cases, 16.7%) and 5) a diffusely enlarged testis with hypoechogenicity (2 cases, 16.7%).Nine patients had ipsilateral epididymitis, and 3 patients had bilateral epididymitis. Pus discharge through the draining sinus tract was noted in 4 cases (33.3%), and hydrocele in 8 cases (66.7%). No parenchymal calcification was seen in the involved testis. Sonographic findings of testicular involvement in tuberculous epididymitis were various

Transverse testicular ectopia - case report  

Directory of Open Access Journals (Sweden)

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

Testicular blood flow in varicocele  

International Nuclear Information System (INIS)

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

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.

Modulation of testicular macrophage activity by collagenase  

OpenAIRE

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 oxyg...

Occupational Causes of Testicular Cancer in Adults  

Directory of Open Access Journals (Sweden)

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

Magnetic resonance imaging of the intradural prepontine chordoma mimicking an epidermoid cyst: Pathologic correlation  

Energy Technology Data Exchange (ETDEWEB)

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

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

Directory of Open Access Journals (Sweden)

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

High-density intracranial epidermoid tumors. Computed tomographic findings in 3 cases  

Energy Technology Data Exchange (ETDEWEB)

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

Prognostic significance of s-phase fraction detected by antithymidine antibodies in epidermoid cervix carcinomas  

International Nuclear Information System (INIS)

Purpose: To assess the predictive value of pretreatment proliferative activity of epidermoid cervix carcinoma cells with respect to short- and long-term results of radiotherapy. Methods and Materials: The proliferative activity of 25 epidermoid cervix carcinomas was evaluated as the immunofluorescent labelling index (LI) by rabbit antithymidine antibodies reacting specifically with single-stranded DNA of replication forks in S-phase cells. The short-term clinical outcome was estimated at 3-6 months after treatment by visual and palpatory examination. Three-year follow-up data were obtained through hospital charts and correspondence with referring physicians for only 19 patients. Results: There was no statistically significant association between LI and such conventional prognostic factors as clinical stage. The LI value of cervix carcinomas was significantly associated with complete regression at 3-6 months after radiotherapy and 3-year disease-free survival. Complete regression at 3-6 months was observed in 87.5% patients with fast proliferating tumors (LI > 7.0%), and only in 41.2% patients with slowly proliferating tumors (p = 0.03). Probability of 3-year disease-free survival was 85.7% in patients with fast proliferating tumors and 50.0% in those with slowly proliferating tumors (p = 0.05). Conclusions: The immunofluorescent LI of epidermoid cervix carcinoma is able to provide prognostic information on short-term tumor response to radiotherapy and disease-free surponse to radiotherapy and disease-free survival

Endoscopic excision of a lateral ventricular epidermoid—A case report of a novel technique  

Science.gov (United States)

INTRODUCTION Epidermoids of the lateral ventricle are relatively rare tumours. As these tumours are soft and relatively avascular, they appear to be ideally suited for endoscopic surgical excision. At present the instruments available are specifically designed for endoscopic intra ventricular surgeries, limitations being inability to rapidly debulk the tumour and achieve adequate haemostasis. We present a case of lateral ventricular epidermoid that was excised endoscopically using a system originally designed for endoscopic disc surgery. PRESENTATION OF CASE We describe a female patient who presented with recurrent headache and occasional episodes of vomiting since 6 years. Preoperative diagnosis of lateral intra ventricular epidermoid was made with the help of an Magnetic resonance imaging (MRI) of the brain. Intraoperatively, an incision was made over the right Kocher's point and a 2.5 cm dural opening was made following a small craniotomy and the Destaudeau endoscope was introduced. A 30° scope and gentle manipulation were used to view the ventricular cavity and ensure near total excision of the tumour. Here we record this novel technique. DISCUSSION Lateral intra-ventricular tumours are usually approached through a trans-cortical or intra hemispheric approach, under microscope. The use of endoscopes have been largely restricted because of non-availability and relative difficulty in controlling troublesome bleeding, incase of vascular tumours. CONCLUSION A multi portal endoscope that allows use of routine pituitary instruments would enable the surgeon to achieve haemostasis effectively and, in our opinion, should be a viable alternative to microscope for excision of intra ventricular tumours.

Full Text Available Introduction: Epidermoids cysts are benign and rare lesions in oral cavity. It presents as a nodular lesion of sessile base, soft to palpation. In the oral cavity, it most happens on the floor of the mouth’s midline. Without treatment, these lesions can lead to dysphagia, dysphonia and dyspnea due to reach a large size. Objective: To report a case of a 12-year-old boy presenting a lesion on the tongue’s ventral surface causing difficult to swallow. Case report: The patient was referred to the School of Dentistry of Paulista University, complaining about an asymptomatic nodule on the tongue’s ventral surface, lasting for 10 months. Clinical examination showed the extensive fibrous mass on the tongue’s medium anterior ventral surface. Conclusion: With a clinical diagnosis of dermoid, epidermoid cyst, or lipoma, an excisional biopsy was performed. Histological examination was consistent to the diagnosis of epidermoid cyst. The patient was followed up and 2 years after surgery there was no sign of recurrence.

Quiste broncogénico de la pared torácica: Caso clínico y revisión de la literatura Bronchogenic cyst in the chest wall  

Directory of Open Access Journals (Sweden)

Full Text Available Los quistes broncogénicos se ubican en la mayoría de los casos en la cavidad torácica, en relación con el árbol bronquial, en la periferia del parénquima pulmonar o en el mediastino. Sin embargo, existen casos infrecuentes en que el quiste se localiza en la pared torácica, principalmente en el tejido celular subcutáneo presternal, en la región cervical y el abdomen. Se postula que la ubicación fuera de la cavidad torácica ocurre por migración, o pinzamiento del tejido pulmonar normal durante la fusión de los procesos esternales o diafragmáticos. En este artículo, se presenta como caso clínico, un paciente 10 años de edad, de sexo masculino, que presentó una lesión nodular presternal, confirmada como quiste broncogénico en el estudio histológico. Se revisa la literatura al respecto y se discute el enfoque diagnóstico y terapéutico más adecuado a esta patologíaThe majority of bronchogenic cysts are found in the thoracic cavity, principally the bronchial tree, the peripheral lung parenchyma or the mediastinum. However, infrequently the cysts are found in the thoracic wall, mainly in the presternal subcutaneous tissues, the cervical region or the abdomen. It is postulated that cysts found outside the thoracic cavity occur by migration or by entrapment of normal pulmonary tissue during the embryonic fusion of the sternum or diaphragm. We present a case of a 10 year old boy who presented with a nodular presternal lesion, histologically confirmed as a brochogenic cyst. We review the literature and discuss the diagnosis and most adequate treatment

Material/Resultados: Se realiza un [...] a presentación y comentarios de las características del caso clínico, así como una revisión de la literatura. Conclusiones: El linfoma testicular primario es un tumor testicular infrecuente, suponiendo no más del 9% de los tumores testiculares en las series con mayor incidencia; a su vez el linfoma testicular como tumor hematopoyético es infrecuente, con una incidencia del 1% de los linfomas, pero debido a su histopatología en la mayoría de los casos de alta malignidad, les hace ser de los tumores testiculares más agresivos. La edad de aparición es por encima de los 60 años, convirtiéndose en el tumor más frecuente para este grupo de edad. En el momento del diagnóstico el 70% de los pacientes presentan estadios I y II de Ann Arbor. Cuando el debut es en forma de estadio avanzado, las localizaciones extranodales más frecuentes son el sistema nervioso central, la piel, el anillo de Waldeyer y el pulmón. Abstract in english We report the case of a 65-year-old man who presented with a right testicular mass and synchronous involvement of skin and Waldeyer's ring. These facts led us to the working diagnosis of malignant primary testicular lymphoma. Material/Results: We present the case with comments and make a bibliograph [...] ic review of the disease. Conclusions: Primary testicular lymphoma is an uncommon testicular tumour that accounts for not more that 9% of all testicular tumours in the series with higher incidence. Testicular lymphomas are also rare among haematopoietic tumours, accounting for just 1% of all lymphomas, but due to their highly malignant histopathology they may become highly aggressive tumours. Patient age at presentation is over 60 years which makes it the most frequent tumour for this age group. 70% of recently diagnosed patients show Ann Arbor stages I and II. Tumours in advanced-stage have a predilection for spreading to extranodal sites such as central nervous system, skin, Waldeyer's ring and lungs.

Tratamiento laparoscópico del quiste hidatídico hepático / Laparoscopic treatment of liver hydatid cysts  

Scientific Electronic Library Online (English)

Full Text Available El objetivo es mostrar los detalles técnicos, protocolo de manejo, costos y resultados del tratamiento laparoscópico de quiste hidatídico hepático (QHH). 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.

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 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.

Testicular Cancer Survivorship: Research Strategies and Recommendations  

Science.gov (United States)

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

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.

Sin embargo, tumores malignos de la cabeza y el cuello pueden presentarse ocasionalmente con metástasis quísticas. Se presenta el caso de una paciente de 33 años asintomática con una masa cervical quística de gran tamaño con 1 año de evolución, que inicialmente fue manejada como un quiste branquial, en quien luego de estudios por imagen e histopatológicos se sospechó carcinoma papilar de tiroides. Este diagnóstico fue corroborado en el trans-operatorio y se trató con tiroidectomía total, disección ganglionar del compartimiento central y disección ganglionar radical modificada derecha. El diagnóstico definitivo en el espécimen quirúrgico fue de un microcarcinoma papilar de tiroides con metástasis ganglionares quísticas y posteriormente la paciente recibió terapia con yodo radioactivoCystic cervical masses are usually benign in the young adult population. However malignant tumors of the head and neck may present ocasionally as cystic metastasis. Herein we report a case of a 33 year old female patient, asymptomatic, with a huge cystic cervical mass of 1 year data. The initial diagnosis was a branchial clef cyst, but after imaging studies and histopathologic examination papillary thyroid carcinoma was suspected. This diagnosis was confirmed in an intraoperatory consultation, so a total thyroidectomy, central lymph node dissection and modified radical neck dissection was performed. The final diagnosis on the surgical specimen was a papillary microcarcinoma of the thyroid with cystic lymph node metastasis and the patient received radioactive iodine afterwards

El caso que se presenta corresponde a una paciente con una tumoración fluctuante en el espacio retroperitoneal lumbar, secundaria a un quiste hepático. El diagnóstico inicial de c [...] erteza fue dado por el hallazgo de ganchos rostelares de protoescólices en el líquido aspirado de un absceso. Este trabajo describe el cuadro clínico, el diagnóstico y el tratamiento médico-quirúrgico de esta paciente. Se analiza cómo la elaboración de un diagnóstico certero requiere de un análisis adecuado de los antecedentes epidemiológicos, las manifestaciones clínicas, los estudios de imágenes y las pruebas de laboratorio, ya que el conjunto de estos datos confirman el caso. Abstract in english Hydatid disease in a worldwide zoonosis. It is caused by a parasitic platyhelminth of the genus Echinococcus. We present a patient with a fluctuating lumbar tumor in the retroperitoneal space, secondary to a hepatic cyst. The initial diagnosis was made by identification of rostellar hooks from proto [...] scoleces in the fluid aspirated from the abscess. We herein describe the clinical manifestations, diagnosis and medical and surgical treatment of this unusual case and conclude that the development of an accurate diagnosis required a proper analysis of the patient's epidemiological history, clinical manifestations, imaging studies and laboratory tests. A multidisciplinary approach and differential diagnosis is paramount to be able to establish a cause of the disease to deliver appropriate treatment.

Estos apéndices pueden sufrir torsión causando un cuadro conocido como escroto agudo. El presente trabajo tuvo como objetivo determinar las variaciones [...] de los apéndices testicular y epididimario, registrando su forma y tamaño. Se utilizaron 30 cadáveres de indivíduos adultos, Brasileños, con edades comprendidas entre 18 y 70 años, fijados en formaldehído 40%, facilitados por el Laboratorio de Anatomía Descriptiva y Topográfica de la Universidad Federal de Alagoas (UFAL), Maceió, Brasil. A través de disección se identificó la presencia de los respectivos apéndices, los que fueron medidos con un caliper manual (MetricaR), registrando su longitud y anchura. Los apéndices testiculares fueron observados en 41 testículos (68,3%) y los apéndices epididimarios en 15 casos (25%). El promedio de la longitud fue de 4,9 mm (DE=1,7) para el apéndice testicular y de 5,2 mm (DE=2,4) para el epididimario. Con respecto a la anchura de los apéndices, el promedio registrado fue de 3,2 mm (DE=1,7) para el testicular y de 2,6 mm (DE=0,9) para el epididimario. Los datos obtenidos puede ser utlizados como soporte morfológico a la clínica urológica y cirugía testicular. Abstract in english Testicular and epididymal appendages are embryologic remnants of the mesonephric duct and paramesonephric, respectively. These appendices are subject to a torsion causing condition known as acute scrotal syndrome. This study aimed to determine the variations of testicular and epididymal appendices, [...] registering its presence and size. We studied 30 cadavers of adult individuals, Brazilians, aged 18 and 70, fixed in formaldehyde 40%, provided by the Laboratory of Descriptive and Topographic Anatomy of the Federal University of Alagoas (UFAL), Maceió, Brazil. By dissecting these, the presence of the respective appendixes were identified, which were measured with a manual caliper (Metrica), recording its length and width. The testicular appendices were observed in 41 testes (68.3%) and epididymal appendices in 15 cases (25%). The average length was 4.9 mm (SD=1.7) for the appendix testis and epididymis to 5.2 mm (SD=2.4). With respect to the width of the appendices, the average recorded were 3.2 mm (SD=1.7) and 2.6 mm (SD=0.9) for testicular and epididymal, respectively. The data obtained can be used as morphological support in urological clinical and testicular surgery.

Testicular function in boys after chemotherapy and/or testicular irradiation for acute leukemia and malignant lymphoma  

Energy Technology Data Exchange (ETDEWEB)

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

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.

[Multilocular epidermoid cyst of the spleen--report of a case observed with an electron microscope].  

Science.gov (United States)

A 27-year-old female, complaining of left hypochondralgia, underwent a splenectomy and a partial pancreatectomy. The spleen, 18.5 x 14 x 6 cm in size and weighing 1060 g., was occupied by a large multicystic mass. The cystic cavities contained turbid chocolate-colored fluid or a yellowish creamy substance. The cysts varied in size and were lined by stratified squamous epithelium. By means of an electron microscope, a few Langer hans cells were seen in the stratified squamous epithelium, but melanocytes and Merkel cells were not noticed. Twenty-eight cases of splenic epidermoid cysts reported in Japan are briefly reviewed. PMID:3346999

Computed tomography and magnetic resonance imaging features of a rare case of a primary epidermoid tumor of the jugular foramen  

Science.gov (United States)

We present computed tomography (CT) and magnetic resonance imaging (MRI) features of a very rare case of a primary epidermoid tumor of the jugular foramen (JF). A 45-year-old male patient presented with gradually progressive vertigo and tinnitus. CT and MRI scans revealed a 3.5 cm right-sided JF tumor with characteristic bright signal (restricted diffusion) on diffusion-weighted MRI (DWI). DWI may be useful in accurately differentiating the lesion from other cystic neoplasms of the JF. We describe the imaging features of intracranial epidermoid and JF tumors and discuss its differential diagnosis.

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

International Nuclear Information System (INIS)

Treatment was studied of oro-facial epidermoid carcinoma by combined chemo- and radiotherapy and eventual surgery. Cytostatic drugs were applied intraarterially. After a monocytostatic treatment trial with Methotrexate (MTX), a combined cytostatic program was developed alternating two cytostatic drugs, viz., MTX and Bleomycin (BLM). The usefulness of chemotherapy and its inclusion in the treatment of epidermoid carcinoma in the oro-facial region was found justified for combined therapy. The selected intraarterial administration, however, is not suitable for routine application. For this reason, the combination irradiation or surgical therapy with chemotherapy was adopted. (author)

Testis Sparing Surgery For Epidermoid Cyst of Testis in an Infertile Man  

Directory of Open Access Journals (Sweden)

Full Text Available In this case report, testis sparing surgery, performed for a heterogenous testicular mass in a 25 year-old man was presented. The patient was infertile for five years. Preoperative ultrasound findings allowed us to such surgery. Intraoperative frozen sectioning showed the benign nature of the lesion, consistent with the final histologic examination. For aesthetic, cosmetic, psychologic and fertility preserving benefits, treatment selection of testis sparing surgery in some testicular masses should be carried out according to clinical, radiological and frozen section findings.

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Objetivo: Los Quistes Renales Simples (QRS) son, en general, asintomáticos y no requieren tratamiento. Para los QRS que ameritan terapéutica quirúrgica, la vía laparoscópica ofrece una opción mínimamente invasiva. El objetivo del presente trabajo es mostrar los resultados obtenidos con esta técnica [...] quirúrgica en nuestra institución. Métodos: Se analizaron en forma retrospectiva 41 casos de pacientes con QRS sintomáticos que fueron tratados mediante marsupialización laparoscópica; todas realizadas por el mismo equipo quirúrgico entre noviembre de 1992 y mayo de 2006. Las vías de abordaje utilizadas fueron la endoscópica transperitoneal y retroperitoneal. Se registraron datos demográficos y perioperatorios de forma prospectiva en una base de datos. Resultados: En el período comprendido entre noviembre de 1992 y mayo de 2006, 41 pacientes fueron operados con el diagnóstico de QRS. La serie estaba formada por 23 (56%) mujeres y 18 (44%) hombres con una edad promedio de 54 años (rango: 27-74 años). Todos los pacientes tratados presentaban síntomas, siendo el más frecuente dolor. El tamaño promedio de las lesiones fue de 10 cm. (rango: 5-16 cm.). Se realizó abordaje transperitoneal en 24 pacientes (58%) y retroperitoneal en 17 (42%). Dieciséis quistes se localizaron en el riñón izquierdo (39%), 24 en el derecho (54%) y un caso era bilateral (3%). El tiempo operatorio promedio fue de 52 min. (rango: 20-150 min.), la estadía hospitalaria fue de 42 horas (rango: 12-96 h.). Treinta y nueve de las lesiones (95.2%) correspondieron al tipo Bosniak I y 2 (4.8%) al tipo Bosniak II. La patología final confirmó QRS en todas las lesiones. Se presentó una única recidiva que fue resuelta con tratamiento percutáneo. Conclusión: La marsupialización laparoscópica es una excelente opción quirúrgica para el tratamiento de los QRS sintomáticos, siendo este tratamiento realizable y seguro. Abstract in english Objectives: Simple renal cysts (SRC) are usually asymptomatic and do not require any kind of treatment. Laparoscopy is a reasonable minimally invasive surgical option for symptomatic cysts. Herein, we present the results of the laparoscopic technique for the treatment of symptomatic renal cysts perf [...] ormed in our institution. Methods: Between November 1992 and May 2006, 41 patients with symptomatic renal cysts were laparoscopically treated. The surgical techniques employed were transperitoneal and retroperitoneal. Demographic and surgical data was prospectively collected and analysis retrospectively performed. Results: 41 patients were treated for symptomatic renal cysts in a fourteen year period. 23 (56%) women and 18 (44%) men, with a median age of 54 years. (Range 27-74 years.). All patients in the series were symptomatic. Pain was the most frequent symptom. Median cyst size was 10 cm. (range 5-16 cm.). Transperitoneal approach was performed in 24 patients (58%) and retroperitoneal in 17 (42%). No differences were verified between these approaches. 16 lesions were located at the left renal unit, 24 in the right renal unit (54%) and one case presented bilateral lesions (3%). Median operative time was 52 min. (range 20-150 min.), median hospital stay was 42 hours (range 12-96 h.). 39 cysts (95.2%) were classified as Bosniak’s type I lesions, 2 lesions (4.8%) were type II based on Bosniak’s description. Final pathology confirmed every lesion as a simple renal cyst. There was only one relapse in the series. The latter was treated percutaneously. Conclusions: Laparoscopy is a feasible, safe and advantageous surgical therapeutic option for symptomatic renal cysts.

Testicular sperm retrieval at the time of bilateral radical orchiectomy  

Directory of Open Access Journals (Sweden)

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

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.

Retrospective study of the global survival and local control after post-operative radiotherapy of head and neck epidermoid cancers  

International Nuclear Information System (INIS)

The authors report the analysis of determining factors of global survival and of survival without recurrence within a cohort of 166 patients treated by post-operative irradiation for an epidermoid carcinoma of the upper aero-digestive tract. The analysis reveals the impact of capsular effraction on global survival and justifies a radiotherapy boost and a concomitant chemotherapy. Short communication

Laparoscopic resection of epidermoid cyst arising from an intrapancreatic accessory spleen: a case report with a review of the literature.  

Science.gov (United States)

We describe a rare case of epidermoid cyst arising in an intrapancreatic accessory spleen that presented as a cystic mass in the tail of the pancreas, and for which laparoscopic distal pancreatectomy was performed successfully. A 36-year-old woman with a cystic mass in the tail of the pancreas, which had been discovered incidentally at a medical checkup, was referred to our department for further examination. Endoscopic retrograde cholangiopancreatography, endoscopic ultrasonography and positron emission tomography demonstrated a multilocular cyst in the tail of the pancreas without any evidence of malignancy, although differential diagnosis was extremely difficult because of the neoplasm-like appearance of the lesion. Therefore, we performed laparoscopic distal pancreatectomy under a preoperative diagnosis of mucinous cystic neoplasm. Postoperative pathologic examination demonstrated an epidermoid cyst arising from a heterotopic spleen within the pancreas. This is the first report of successful laparoscopic distal pancreatectomy for an epidermoid cyst arising in an intrapancreatic accessory spleen. One virtually has no chance to diagnose an epidermoid cyst in an accessory spleen on the basis of preoperative diagnostic workup, and consequently the type of surgical resection (open vs. laparoscopic) would be conditioned by factors other than the clinical entity suspected at the preoperative period.

Proteomic analysis of testicular ischemia-reperfusion injury in rats.  

Science.gov (United States)

Testicular torsion is a urological emergency that leads to serious testicular damage and male infertility. We performed this study to identify specific proteins that are differentially expressed in response to testicular torsion and detorsion-induced ischemia-reperfusion (I-R) injury. Adult male rats were divided into two groups: a sham-operated group and a testicular I-R group. Testicular torsion was induced by rotating the left testis 720° in a clockwise direction for 1 hr, and then, detorsion was performed for 24 hr. After this testicular tissues were collected, protein analysis was performed using two-dimensional gel electrophoresis and Western blot analyses. Testicular I-R injury resulted in serious histopathologic damage to the germinal cells in the seminiferous tubules and increased the number of TUNEL-positive cells in testicular tissue. Specific protein spots with a greater than 2.5-fold change in intensity between the sham-operated and testicular I-R groups were identified by mass spectrometry. Among these proteins, levels of peroxiredoxin 6, thioredoxin, heterogeneous nuclear ribonucleoproteins, ubiquitin carboxyl terminal hydrolase isozyme L5 and zinc finger AN1-type domain 3 were decreased in the testicular I-R group compared to the sham-operated group. Moreover, Western blot analysis clearly showed the decrease of these proteins in the testicular I-R group. These proteins have spermatogenesis and anti-oxidative functions. These findings suggest that testicular I-R results in cell death due to altered expression of several proteins with spermatogenesis and anti-oxidation functions. PMID:24189580

[Metastatic pure testicular seminoma of the skin].  

Science.gov (United States)

Seminomas are germinal tumors from testicular cells in men. Cutaneous metastasis are very rare. The authors report the case of a 56-year-old male patient admitted for treatment of an enlarged left testicular mass. Physical examination revealed a cutaneous nodule on the right side of the back. Histopathologic examination of both orchiectomy materiel and cutaneous lesion revealed pure seminoma. Chest and abdomen-pelvis CT revealed a pulmonary metastatic nodules, enlarged para-aortic lymph nodes and metastatic lesions in the adrenals glands. The patient died six months after diagnosis due to complications of metastatic disease despite adjuvant chemotherapy. To our knowledge, we report the first case demonstrating that seminoma may spread to skin. PMID:21193150

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 Cancer Survivorship: Research Strategies and Recommendations  

OpenAIRE

Testicular cancer represents the most curable solid tumor, with a 10-year survival rate of more than 95%. Given the young average age at diagnosis, it is estimated that effective treatment approaches, in particular, platinum-based chemotherapy, have resulted in an average gain of several decades of life. This success, however, is offset by the emergence of considerable long-term morbidity, including second malignant neoplasms, cardiovascular disease, neurotoxicity, nephrotoxicity, pulmonary t...

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.)

Perinatal testicular torsion and medicolegal considerations.  

Science.gov (United States)

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

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

International Nuclear Information System (INIS)

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

Variation in the Origin of the Testicular Arteries and Drainage of the Right Testicular Vein Variación en el Origen de las Arterias Testiculares y el Drenaje de la Vena Testicular Derecha  

Directory of Open Access Journals (Sweden)

Full Text Available During routine dissection of a 42 year old male Indian cadaver posterior abdominal wall, variations in the testicular vessels were observed. The right testicular artery arose from the right accessory renal artery, which originated from the ventral aspect of the abdominal aorta. The left testicular artery originated from the ventral aspect of the aorta in almost the same horizontal line as the right accessory renal artery, just below the superior mesenteric artery and 1.79 cm, above the origin of the renal arteries. The right vein drained into the right accessory renal vein instead of the inferior vena cava, while the left testicular vein drained into the left renal vein. The presence of variation of both the testicular arteries as well as the testicular vein is seldom seen together.Durante una disección de rutina de un cadáver, perteneciente a un hombre indio de 42 años, se observaron variaciones en los vasos testiculares en la pared abdominal posterior. La arteria testicular derecha se originó desde la arteria renal accesoria, proveniente de la cara ventral de la parte abdominal de la aorta. La arteria testicular izquierda se originó en la cara ventral de la parte abdominal de la aorta, casi en la misma línea horizontal de la arteria renal accesoria derecha, justo distal a la arteria mesentérica superior y 1,79 cm sobre el origen de las arterias renales. La vena renal derecha drenaba en la vena renal accesoria en lugar de la vena cava inferior, mientras que la vena testicular izquierda drenaba en la vena renal izquierda. En muy pocas ocasiones es posible observar de manera conjunta, variaciones tanto de las arterias como de las venas testiculares.

Variation in the Origin of the Testicular Arteries and Drainage of the Right Testicular Vein / Variación en el Origen de las Arterias Testiculares y el Drenaje de la Vena Testicular Derecha  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: English Abstract in spanish Durante una disección de rutina de un cadáver, perteneciente a un hombre indio de 42 años, se observaron variaciones en los vasos testiculares en la pared abdominal posterior. La arteria testicular derecha se originó desde la arteria renal accesoria, proveniente de la cara ventral de la parte abdomi [...] nal de la aorta. La arteria testicular izquierda se originó en la cara ventral de la parte abdominal de la aorta, casi en la misma línea horizontal de la arteria renal accesoria derecha, justo distal a la arteria mesentérica superior y 1,79 cm sobre el origen de las arterias renales. La vena renal derecha drenaba en la vena renal accesoria en lugar de la vena cava inferior, mientras que la vena testicular izquierda drenaba en la vena renal izquierda. En muy pocas ocasiones es posible observar de manera conjunta, variaciones tanto de las arterias como de las venas testiculares. Abstract in english During routine dissection of a 42 year old male Indian cadaver posterior abdominal wall, variations in the testicular vessels were observed. The right testicular artery arose from the right accessory renal artery, which originated from the ventral aspect of the abdominal aorta. The left testicular a [...] rtery originated from the ventral aspect of the aorta in almost the same horizontal line as the right accessory renal artery, just below the superior mesenteric artery and 1.79 cm, above the origin of the renal arteries. The right vein drained into the right accessory renal vein instead of the inferior vena cava, while the left testicular vein drained into the left renal vein. The presence of variation of both the testicular arteries as well as the testicular vein is seldom seen together.

[Laryngeal epidermoid carcinoma in a young adult without risk factors: a case report].  

Science.gov (United States)

Head and neck carcinomas are rare in young patients without a history of tobacco consution, tho two classical risk factors. Our report is about 20 year-old patient without a history exosure to radiations or of alcohol / tobacco consumption, who presented with repeated episodes of dysphonia that didn't improve under medical treatment. Endoscopy showed a fungating hemilaryngeal lesion with a histology of epidermoid carcinoma stage T3N0. The patient initially 3 courses of cisplatin-5 fluorouracil resulting in a 90% objective response, followed by a loco-regional radiotherapy. 36 months after the diagnosis and 24 after the end of therapy, the patient is still alive and in complete remission.

Fast neutron teletherapy in advanced epidermoid head and neck cancer. A review.  

Science.gov (United States)

An extensive review of clinical studies employing fast neutron teletherapy for advanced epidermoid carcinomas of the head and neck is presented. Head and neck tumors have represented an excellent study site because of their accessibility to physical examination for measurement of tumor response, and because early neutron beams have had poor depth dose characteristics, making the treatment of more deeply seated tumors technically difficult. A summary of the major trials comparing neutron and mixed-beam (combination neutron and photon) therapy with conventional therapy indicates no conclusive evidence of improvement in local control or survival rates for the experimental arms. Exceptions to this are the Hammersmith experience and the slightly higher lymph node control rates seen in two studies. An evaluation of toxicity indicates that with the new generation of cyclotrons, complication rates may approach parity with those of photon linear accelerators. PMID:2667319

Epidermoid cyst inside anterior sacral meningocele in an adult patient of Currarino syndrome manifesting with meningitis.  

Science.gov (United States)

The Currarino triad, also known as the "Currarino Syndrome", is a rare complex of congenital caudal anomalies including three main features; a sacral bony deformity, anorectal malformations, and a presacral mass. We present an extremely uncommon case of Currarino syndrome in adulthood presenting with repeated episodes of meningitis. Magnetic resonance imaging of spine was suggestive of caudal regression. Cord was low lying, conus ending at L3 level with evidence of tethering at that level. A large cyst was noted in the sacral canal extending forwards in the pelvis through the widened sacral foramina on right side. She was operated through a posterior approach, via sacral laminectomy. Dura was opened in the midline, large silvery white epidermoid tumor was found completely occupying the anterior sacral meningocele. The case and relevant literature is discussed. PMID:23015348

Spermatic vein phlebography in patients with testicular tumors.  

Science.gov (United States)

The performance of funicular lymphography and spermatic vein phlebography during orchiectomy in patients with testicular tumors demonstrates the close proximity of the spermatic vein to the lymph nodes draining the testicles. In the case of metastatic lymph node involvement the spermatic vein phlebography may add supplementary diagnostic information. The examination was proved successful in eight patients with malignant testicular tumors. PMID:904745

Testicular niche required for human spermatogonial stem cell expansion.  

Science.gov (United States)

Prepubertal boys treated with high-dose chemotherapy do not have an established means of fertility preservation because no established in vitro technique exists to expand and mature purified spermatogonial stem cells (SSCs) to functional sperm in humans. In this study, we define and characterize the unique testicular cellular niche required for SSC expansion using testicular tissues from men with normal spermatogenesis. Highly purified SSCs and testicular somatic cells were isolated by fluorescence-activated cell sorting using SSEA-4 and THY1 as markers of SSCs and somatic cells. Cells were cultured on various established niches to assess their role in SSC expansion in a defined somatic cellular niche. Of all the niches examined, cells in the SSEA-4 population exclusively bound to adult testicular stromal cells, established colonies, and expanded. Further characterization of these testicular stromal cells revealed distinct mesenchymal markers and the ability to undergo differentiation along the mesenchymal lineage, supporting a testicular multipotent stromal cell origin. In vitro human SSC expansion requires a unique niche provided exclusively by testicular multipotent stromal cells with mesenchymal properties. These findings provide an important foundation for developing methods of inducing SSC growth and maturation in prepubertal testicular tissue, essential to enabling fertility preservation for these boys.

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

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

TESTICULAR CANCER – THE SUCCESS OF MULTIMODAL THERAPY  

Directory of Open Access Journals (Sweden)

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

Ultrasonographic Findings of Prepubertal Testicular Teratoma  

International Nuclear Information System (INIS)

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

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).

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 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.

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.

[Transverse testicular ectopia confirmed by ultrasonography].  

Science.gov (United States)

Two newborn boys aged 2 and 3 months with unilateral inguinal hernia and a contralateral impalpable, non-scrotal testis, and a third boy aged 2.5 years with an impalpable non-scrotal testis were found to have transverse testicular ectopia. This is an uncommon abnormality in which both gonads migrate toward the same hemiscrotum. We illustrate that unilateral cryptorchidism and a contralateral inguinal hernia may indicate the presence of a rare type of male pseudohermaphroditism: persistent müllerian duct syndrome (PMDS). This syndrome is characterized by the presence of a uterus and fallopian tubes associated with abdominal testes and frequently inguinal hernia in a phenotypically and genotypically normal male. This syndrome is often discovered during repair of inguinal hernia or non-descended testes (cryptorchidism). Pre-operative ultrasonography in children with impalpable non-scrotal testis and a contralateral inguinal hernia (patent processus vaginalis) may enable an early diagnosis of transverse testicular ectopia and proper surgical planning. Surgical orchidopexy was carried out and in the first two patients resection of the müllerian duct remnant (utriculus masculinus). PMID:20170567

Testicular tumor and the acquired immunodeficiency syndrome.  

Science.gov (United States)

Immunocompromised patients, particularly those suffering from the acquired immunodeficiency syndrome (AIDS), present an increased risk of tumoral pathology. From the observation of a testicular lymphoma associated with Epstein-Barr virus in a HIV + patient, we review 19 cases of testicular tumor in HIV + patients previously published in the literature. These tumors are either lymphomas (4 cases) or germ cell tumors (15 cases). Their diagnosis was not difficult, although in the first stages enlarged and painful testicles are often wrongly identified as orchiepididymitis and treated as such. Therapy management proves to be delicate as a result of the significant tumor spread seen in these patients with dysfunctional immune systems. Regarding lymphomas, a low-dose multiagent chemotherapy with intrathecal chemotherapy was recommended by Levine. Concerning germ cell tumors, Wilson prefers an instant aggressive treatment with retroperitoneal lymphadenectomy (whether or not combined with chemotherapy) to avoid the risk of recurrence. In fact, tumor relapses will be difficult to control in the progressive stages of immunodeficiency syndrome. PMID:7925534

Induction of apoptosis and antiproliferative activity of naringenin in human epidermoid carcinoma cell through ROS generation and cell cycle arrest.  

Science.gov (United States)

A natural predominant flavanone naringenin, especially abundant in citrus fruits, has a wide range of pharmacological activities. The search for antiproliferative agents that reduce skin carcinoma is a task of great importance. The objective of this study was to analyze the anti-proliferative and apoptotic mechanism of naringenin using MTT assay, DNA fragmentation, nuclear condensation, change in mitochondrial membrane potential, cell cycle kinetics and caspase-3 as biomarkers and to investigate the ability to induce reactive oxygen species (ROS) initiating apoptotic cascade in human epidermoid carcinoma A431 cells. Results showed that naringenin exposure significantly reduced the cell viability of A431 cells (p<0.01) with a concomitant increase in nuclear condensation and DNA fragmentation in a dose dependent manner. The intracellular ROS generation assay showed statistically significant (p<0.001) dose-related increment in ROS production for naringenin. It also caused naringenin-mediated epidermoid carcinoma apoptosis by inducing mitochondrial depolarization. Cell cycle study showed that naringenin induced cell cycle arrest in G0/G1 phase of cell cycle and caspase-3 analysis revealed a dose dependent increment in caspase-3 activity which led to cell apoptosis. This study confirms the efficacy of naringenin that lead to cell death in epidermoid carcinoma cells via inducing ROS generation, mitochondrial depolarization, nuclear condensation, DNA fragmentation, cell cycle arrest in G0/G1 phase and caspase-3 activation.

Primary intracranial sarcomatoid carcinoma arising from a recurrent/residual epidermoid cyst of the cerebellopontine angle: a case report.  

Science.gov (United States)

Primary intracranial squamous cell carcinomas (SCCs) are rare and mostly associated with an intracranial epidermoid or dermoid cyst. Sarcomatoid carcinoma is a rare biphasic tumor composed of both carcinomatous and sarcomatous components and has not previously been reported as a primary intracranial tumor. Here, we present a case of a 60-year-old man with a primary intracranial sarcomatoid carcinoma, arising from the remnants of the previously resected epidermoid cyst in the cerebellopontine angle. The resected material had portions of an epidermoid cyst lined by normal and dysplastic squamous epithelia and invasive keratinizing SCC. This area was in continuity with areas of highly pleomorphic, anaplastic sarcomatoid cells. Brisk mitotic activity and extensive areas of necrosis were found. On immunohistochemical staining, the cells of the conventional SCC were positive for cytokeratin 5/6, pancytokeratin, epithelial membrane antigen, p63, and p53. The sarcomatoid cells were diffusely and strongly positive for vimentin, p53, smooth muscle actin, and, focally, muscle-specific actin. Occasional sarcomatoid cells coexpressed cytokeratin 5/6, pancytokeratin, p63, and S100 protein. The patient subsequently developed leptomeningeal spread and died 4 months after the second surgery. This rare entity expands the morphologic spectrum encountered in primary intracranial carcinoma. PMID:21753701

The effect of neonatal vasectomy on testicular function.  

Science.gov (United States)

The effect of unilateral or bilateral vasectomy on testicular weight and basal testosterone production in vitro was studied in neonatal intact and hemicastrated rats. Five days after right-side vasectomy ipsilateral to vasectomy testicular weight increased, and basal testosterone production decreased. Ten days postvasectomy the changes were opposite, and affected both testes. In hemicastrated animals hemivasectomy did not interfere with compensatory hypertrophy but induced a significant decrease in basal testosterone production. The data of the present study suggest that in neonatal animals intact ductus deferens bundle(s) is also required for the full control of testicular weight and basal testosterone secretion.

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

Currently, the treatment plan is primarily empirical, with the first approach consisting of clinical measures. However, some patients remain in pain despite a conservative treatment protocol and, for them, it is pos [...] sible to perform a surgical procedure that involves severing the scrotal and spermatic branches of the genitofemoral and ilioinguinal nerve fibers. METHODS: In our institution, 60 patients were evaluated and treated for idiopathic chronic testicular pain between January 2003 and July 2007. Priority was give to clinical treatment, which evolved from simple to more complex measures. Microsurgical treatment was performed on those who experienced no considerable pain relief (10 individuals in our study). RESULTS: Over a twenty-four-month follow-up period, 70% of patients showed complete remission and 20% exhibited partial relief from pain.

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

International Nuclear Information System (INIS)

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

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.

Reversible harmless interruption of testicular blood supply in the ram  

International Nuclear Information System (INIS)

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

Detection of Protein BCL2/JH Rearrangement in Epidermoid Carcinomas of Mouth and Pharynx  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: The BCL2 protein found in the internal mothocondrial membrana regulates the apoptosis preventing the programmed cell death. The translocation (14:18, detected in 70 to 85% of the follicular lymphoma, lead the super expression of BCL2 protein, by juxtaposition of BCL2 gene to the JH segment of the immunoglobulins' heavy chain gene. However, the found of the BCL2 expression in head and neck carcinoma are contradictious. Objective: To investigate the presence of the translocation (14:18 of the BCL2 gene in head and neck carcinoma. Method: Sixteen DNA samplers were examinated being 13 of squamous cells carcinoma (SCC and 3 of epidermoid (CE, y means of chain reaction of the polymerase (PCR. Results: The BCL2/JH rearrangement in 2 (15% of the CCE 13 cases and in none of the 3 cases of CE. The average of the frequency of molecules with rearrangement was 46,44x107. Was not observed association between the rearrangement presence and the exhibition to tobacco and alcohol (p=0, 6545. Conclusion: Different from the results found in follicular lymphoma, the presence of the translocation (14; 18 in head and neck carcinomas is not common and, when it occurs, it can be an occasional mutation not associated to exhibition to the tobacco and alcohol.

Epidermoid carcinoma of the anal margin: 17 cases treated with curative-intent radiation therapy  

International Nuclear Information System (INIS)

Between 1973 and 1991, 17 patients with epidermoid carcinoma of the anal margin without evidence of distant metastasis were treated with curative-intent radiation therapy (RT). There were nine T1-tumors, six T2-, one T3- and one T4-tumor; two patients presented with inguinal node involvement: one N1 and one N3. Nine patients underwent prior incomplete local excision (six with microscopic involvement of surgical margins and two with macroscopic residual disease). The radiation dose to the tumor was 60-70 Gy; the radiation dose to the inguinal lymph nodes was 40-45 Gy in N0, and 50-60 Gy for involved inguinal nodes. The 5- and 10-year cancer-specific survival rates were 86.2% and 77.5%, respectively. The same probabilities were 100% and 100% for T1-tumors, 60% and 40% for T2-tumors. Severe complications occurred in two patients, one anal radionecrosis requiring a colostomy and one permanent anal incontinence after local excision. which was non-related to irradiation. For the cured patients, the sphincter preservation rate after 5 years was 82% ((9(11))). In univariate analysis and in Cox multivariate analysis, the cancer-specific survival rate was influenced by one factor: the tumor size

Epidermoid cyst in the cerebellopontine angle cistern presenting as trigeminal neuralgia  

International Nuclear Information System (INIS)

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

Phosphorylation of chloroform soluble compounds in plasma membranes of human epidermoid carcinoma A431 cells  

International Nuclear Information System (INIS)

This study investigated a possible role for the epidermal growth factor (EGF) receptor protein tyrosine kinase in phosphoinositide metabolism with plasma membrane vesicles from human epidermoid carcinoma (A431) cells. The authors found a novel chloroform-soluble product radiolabeled with [gamma-32P]ATP that did not migrate from the origin in the thin layer system designed to separate the phosphoinositides, appeared as a single band of Mr = 3500 on polyacrylamide gels in the presence of dodecyl sulfate, had an ultraviolet absorbance spectrum with a maximum at 275 nm and stained with Coomassie dye. Based on these properties this phosphorylation product is referred to as a proteolipid. The 32P label was not detected in phosphotyrosine [Tyr(P)], phosphoserine [Ser(P)] or phosphothreonine [Thr(P)] and was lost during acid or base hydrolysis. Phosphorylation of proteolipid was increased significantly by EGF, whereas phosphorylation of phosphatidic acid was decreased and labeling of phosphoinositides was unaffected. Thus, it appears that in A431 membranes the EGF receptor/kinase does not utilize phosphatidylinositol as a substrate, but does phosphorylate a membrane proteolipid

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.

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.

Testicular development and reproductivity in rats  

Energy Technology Data Exchange (ETDEWEB)

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

Altered levels of pregnancy hormones have been suggested to initiate testicular cancer prenatally in the male fetus. The placenta is the main source of pregnancy hormones, and pregnancy hypertension and preeclampsia are associated with placental malfunction, including altered levels of hormones such as estrogen and human chorionic gonadotropin. We therefore evaluated fetal exposure to pregnancy hypertension and preeclampsia in relation to risk of testicular cancer in adolescent and adult life...

Testicular descent is a unique physiological adaptation found in therian mammals allowing optimal spermatogenesis below core body temperature. Recent studies show that INSL3, produced by Leydig cells, and its receptor LGR8 (RXFP2) are essential for mediating the transabdominal phase of testicular descent during early development. However, the origin and genetic basis for this physiological adaptation is not clear. Using syntenic mapping and the functional characterization of contemporary and ...

Effects of radiation therapy and chemotherapy on testicular function  

International Nuclear Information System (INIS)

Chemotherapy and radiation therapy are commonly used alone or in combination in the curative management of many malignancies in adolescent and adult males. Over the last 15-20 years, the striking success in the treatment of some common cancers in reproductive males has led to increasing concern for damage to normal tissues, such as the testes, resulting from curative cancer treatment. Indeed, a major future goal for cancer treatment will be to improve on the complication-free cure rate. Inherent in achieving this goal is to understand the pathophysiology and clinical expression of testicular injury. Both chemotherapy and radiation therapy result in germ cell depletion with the development of oligo- to azoospermia and testicular atrophy. The type of drug (particularly the alkylating agents), duration of treatment, intensity of treatment, and drug combination are major variables in determining the extent and duration of testicular injury. Testicular injury with chemotherapy also appears to vary with the age of the patient at the time of treatment. Newer drug combinations are now being used which appear to have curative potential in tumors such as Hodgkin's disease and germ cell testicular cancer with less potential for testicular injury. The most accurate and complete information on radiation injury to the testes is derived from two studies of normal volunteers who received graded single doses directly to the testes. A clear dose-response relationship of clinical and hie-response relationship of clinical and histological testicular damage was found with gradual recovery occurring following doses of up to 600 cGy. While these two studies provide an important clinical data base, radiation therapy used in treating cancers involves multiple daily treatments, usually 25-35 delivered over several weeks. Additionally, direct testicular irradiation is seldom used clinically. 37 references

Testicular metastasis of prostate cancer: a case report.  

Science.gov (United States)

The incidence of secondary neoplasms of the testis during autopsies is approximately 2.5%. Although most secondary testicular metastases are due to prostate cancer, only a few patients with prostate cancer have clinically manifested testicular metastasis. We report the case of a prostate cancer patient with testicular metastasis who was diagnosed after the presence of a palpable mass in the right testis. A 56-year-old Japanese male presented to our hospital with an elevated serum prostate-specific antigen (PSA) level of 137 ng/ml. He was diagnosed with stage IV (T3N1M1b) prostate cancer and received androgen deprivation therapy, followed by various hormonal manipulations. His serum PSA level was undetectable for 1 year. No distant metastases were detected during imaging examinations. He received radiation therapy; however, his serum PSA level increased gradually. Four months later, he presented with right testicular swelling. Computed tomography revealed a heterogenous mass in the right testis and a right high inguinal orchiectomy was performed. Histopathological analysis showed that the right testis was infiltrated with metastatic adenocarcinoma with a Gleason score of 8. This is a rare case of right testicular metastasis in a patient with prostate cancer. Testicular metastasis of prostate cancer can be aggressive and metastasize. PMID:25408658

Objective: To expose the characteristics and symptoms of a Skene duc [...] t cyst at different stages of child development in order to carry out a timely suspicion and diagnosis. Case report: The first case is a female newborn who presented a painless yellowish tumor adjacent to the urethral meatus, which drained spontaneously; the second case is a teenager who consulted due to leucorrhea for a year and a three-centimeter diameter paraurethral injury between the labia minora, which required surgical treatment and study of the paraurethral mass. Conclusions: Based on the literature review, we concluded that the frequency of Skene duct cyst is higher than the number of reported cases. Cyst removal, marsupialization, puncture and aspiration are all effective treatment methods. Spontaneous drainage is also appropriate in certain cases. We suggest the use of the least aggressive technique according to each case.

Precocidade sexual em bovinos Nelore avaliada por ultrassonografia testicular / Sexual precocity in Nelore bovines evaluated by testicular ultrasonography  

Scientific Electronic Library Online (English)

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

Onco-testicular sperm extraction: birth of a healthy baby after fertility preservation in synchronous bilateral testicular cancer and azoospermia.  

Science.gov (United States)

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

Re-irradiation in stereotactic conditions and cetuximab for local relapses of epidermoid carcinoma of head and neck; Reirradiation en conditions stereotaxiques et cetuximab pour des recidives locales de carcinome epidermoide de la tete et du cou  

Energy Technology Data Exchange (ETDEWEB)

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

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

International Nuclear Information System (INIS)

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

P53 overexpression in epidermoid carcinoma of the head and neck  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese A teoria de campo de cancerização em neoplasias de cabeça e pescoço (CP) reflete a complexa oncogênese que ocorre nesta região. Os mecanismos a nível molecular que controlam a proliferação celular em Carcinomas epidermóides (CEC) de vias aerodigestivas superiores ainda são pouco conhecidos. Mutações [...] no p53 são as alterações genéticas mais encontradas em CEC de CP e parecem contribuir ativamente em seu processo carcinogênico como gene supressor de tumor e a sua associação com tabaco. O objetivo deste trabalho é analisar a expressão da proteína p53 em carcinoma epidermóide de cabeça e pescoço por meio de reação imunohistoquimica e sua correlação com outros fatores prognósticos. O estudo inclui 63 casos consecutivos de CEC, não tratados previamente. Espécimes de tumor e de mucosa normal adjacente foram colhidos durante o ato cirúrgico e submetidos a reação imunohistoquímica para avaliação da expressão do anticorpo anti-proteína p53 (M7001 DAKO AVS, Denmark Inc.) Não houve significância entre os dados anatomo-clínicos e demográficos, presença de metastases linfonodais e a expressão de p53 no tumor ou na mucosa adjacente normal. A localização do tumor na laringe apresentou correlação estatistica significativa com a expressão da p53 . A graduação histológica, separada em graus I e ll, e III e IV apresentou correlação com a expressão de p53 significante ( p=0,025). Conclusões: 1-No material estudado proveniente de 63 casos de CEC de cabeça e pescoço encontramos 48% de superexpressão de p53 imunohistoquimicamente detectável, índice compatível com os demais relatados na literatura; 2-Não encontramos relação entre os dados demográficos do paciente e a expressão de p53 no tumor e na mucosa normal adjacente; 3- O achado de superexpressão de p53 mais freqüente em Material de CEC de laringe foi estatisticamente significativo. 4-A presença de 12 casos com superexpressão de p53 na mucosa normal adjacente e com tumor p53 negativo esta de acordo com a teoria de cancerização de campo. O seguimento desta série por maior tempo possibilitará uma melhor análise destes valores. Abstract in english The theory of field cancerization in tumors of the head and neck reflects the complex oncogenesis that occurs in this region. The mechanisms that control cell proliferation at the molecular level in epidermoid carcinomas (ECs) of the upper aerodigestive tract are still unclear. Mutations in p53 are [...] the genetic alterations most often detected in ECs of the head and neck and seem to contribute actively to the carcinogenic process triggered by p53 as a tumor-suppressor gene and to its association with tobacco. The objective of the present study was to investigate the expression of p53 protein in epidermoid head and neck carcinomas by immunohistochemistry and its immunohistochemical correlation with other prognostic factors. The study was conducted on 63 consecutive ECs cases not submitted to previous treatment. Specimens of the tumor and of the normal adjacent mucosa were collected during surgery and submitted to immunohistochemical reaction for the determination of the expression of anti-protein p53 antibody (M7001 DAKO A/S, Denmark). Anatomo-clinical and demographic data were not significantly correlated with the presence of lymph node metastases or p53 expression in the tumor or in the adjacent normal mucosa. Tumor localization in the larynx was significantly correlated with p53 expression. Histological grading as grades I, II, Ill and IV was correlated with significant p53 expression (p = 0.025). Conclusions: 1) in the studied material obtained from 63 cases of head and neck ECs, we detected a 48 percent rate of immunohistochemically detectable p53 overexpression; 2) we did not detect a relationship between demographic patient data and p53 expression in the tumor or in the normal adjacent mucosa; 3) p53 overexpression was significantly more frequent in ECs material from the larynx; and

Metástasis neurológicas secundarias a tumor testicular germinal / Neurological metastases secondary to germ cell testicular tumor  

Scientific Electronic Library Online (English)

Full Text Available Objetivo: Las metástasis neurológicas secundarias a tumores urológicos suponen un 12% del total. Las derivadas de los tumores germinales testiculares en la época del cisplatino son excepcionales. Métodos: Presentamos un caso de tumor germinal mixto en un varón de 49 años tratado mediante quimioterap [...] ia sistémica desde 18 meses antes que presentó severa clínica neurológica central y periférica, que le condujo a la muerte por hemorragia cerebral masiva. Resultados: Se describen 3 tipos de presentación de las metástasis cerebrales en pacientes con cáncer testicular. El tipo 1 en el que se presentan sincrónicamente al tumor primario. El tipo 2 en el que se diagnostican tras un período de remisión luego del tratamiento citostático convencional.

Intracranial epidermoid cysts: diffusion-weighted, FLAIR and conventional MR findings  

International Nuclear Information System (INIS)

Purpose: To compare diffusion-weighted echo-planar imaging (DW) with spin-echo (SE), and fluid-attenuated inversion recovery (FLAIR) sequences in the evaluation of epidermoid cysts (ECs), and to evaluate T2 shine-through effect. Materials and methods: Fifteen patients were imaged prospectively in two different 1.5 T magnetic resonance (MR) units with standard head coils with SE, FLAIR and DW echo planar imaging sequences. The qualitative and quantitative assessments were performed by two radiologists in consensus. Apparent diffusion coefficient (ADC) values were obtained from all ECs. Exponential DW images are obtained in 11 cases to eliminate T2 shine-through effects. The results are analyzed with variance analysis (ANOVA) and Bonferroni t method. Results: FLAIR sequence was superior to T1- and T2-weighted sequences in showing ECs. In 13 cases, the borders of the lesions could be delineated from the surrounding structures with only DW imaging where ECs were markedly hyperintense. The ADC values of ECs are significantly lower than CSF (P < 0.001), and significantly higher than deep white matter (P < 0.01). On exponential DW images, ECs had similar intensity with brain parenchyma showing that the real cause of the hyperintensity of the lesions on trace images is the enhanced T2 effect of the tissue. Conclusion: FLAIR sequence is superior to the conventional MR sequences in demonstrating the ECs and DW imaging is superior to other MR sequences in delineating the borderser MR sequences in delineating the borders of the ECs. Exponential DW images had shown that the hyperintensity in the trace images are caused by increased T2 effect of the lesion rather than the decrease in ADC values

Iridium-192 curietherapy for T1 and T2 epidermoid carcinomas of the floor of mouth  

International Nuclear Information System (INIS)

From 1970 to 1986, 117 patients with T1 (47) or T2 (70) epidermoid carcinomas of the floor of the mouth (SCC) were treated by iridium-192 implantation (192 Ir). The dose was prescribed according to the Paris System and varied over those years. Follow-up information was available on 116 patients. There were 46 T1N0, 47 T2N0, and 23 T2N1-3. Neck management varied for the 93 N0 patients consisting of surveillance (24 T1, 17 T2) or elective neck dissection (22 T1:all pN-, 30 T2: 20 pN-, 10 pN+). Cause specific survival rates were 94% for T1N0, 61.5% for T2N0, and 28% for T2N1-3 at 5 years. Primary local control was 93.5%, 74.5%, and 65%, respectively, and 98%, 79%, and 65% after salvage. Patients with gingival extension or a tumor size over 3 cm (T2b) had a local control of 50% (9/18) and 58% (15/26), respectively. Nodal control was 93.5% for Stage I, 85% for Stage II, and 48% for T2N1-3 patients. There was no difference in nodal control with regard to treatment policy for Stage I-II patients. There were few complications including three deaths: two from surgery and one from 192 Ir. Nodal status, tumor size defined as T1, T2a (less than or equal to 3 cm), T2b (greater than 3 cm), and gingival extension were the only independent prognostic factors. The management of T1N0 and T2N0 SCC by 192 Ir to a dose of 65 or 70 Gy, using the Paris System, is recommended for lesions 3 cm or less and without gingival extension

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

International Nuclear Information System (INIS)

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

Intraparenchymal epidermoid cysts in the brain: diagnostic value of MR diffusion-weighted imaging  

International Nuclear Information System (INIS)

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

Re-irradiation in stereotactic conditions and cetuximab for local relapses of epidermoid carcinoma of head and neck  

International Nuclear Information System (INIS)

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

Resultados: Se registraron 4 casos de tumor [...] es bilaterales (un 4,1%) en la serie. El intervalo de aparición del segundo tumor osciló entre 14 meses y 4 años y medio (siendo la mediana de 47 meses). En tres casos el tumor inicial fue un Carcinoma embrionario y en uno un tumor de Leydig. En dos casos el segundo tumor fue del mismo tipo histológico (Ca embrionario y tumor de Leydig), mientras que en los otros dos casos de Ca embrionario, el segundo tumor fue un seminoma y un teratocarcinoma. Respecto a la histología del primer tumor, se observó que sólo 3 de los 27 Ca embrionarios (11%) de nuestra serie, experimentaron una segunda neoplasia frente a 1 de los 2 tumores de Leydig (50%). Conclusiones: La incidencia de tumores bilaterales en nuestra serie fue del 4,1%, en nuestra serie el riesgo de aparición de un segundo tumor parece ser mas elevado en pacientes con tumores de Leydig aunque el pequeño número de caso no son permite extraer conclusiones significativas. Abstract in english Objectives: To study the incidence and characteristic of the bilateral tumours of testicle. Material and methods: It was carried out a retrospective study on a database of testiculars tumours 98 tried in our service among the years 1979 and 2004. Results: We registered 4 cases of bilateral tumours ( [...] 4,1%) in the series. The interval of appearance of the second tumor oscillated between 14 months and 4 and a half years (being the medium of 47 months). In three cases the initial tumour was an embryonic Carcinoma and in one a tumour of Lydia. In two cases the second tumour was of the same type histological (embryonic Ca and tumour of Leydig), while in the other two cases of embryonic Ca, the second tumour was a seminoma and a teratocarcinoma. Regarding the histology of the first tumour, it was observed that only 3 of the 27 embryonic Ca (11%) of our series, they experienced a second neoplasia in front of 1 of the 2 tumours of Leydig (50%). Conclusions: The incidence of bilateral tumours in our series was of 4,1 %. In our series the risk of the second tumour seems to be higher in patients with Leyding tumours, therefore the lesser number of tumours do not allow us to know significantly conclusions.

Androgen receptor polymorphisms and testicular cancer risk.  

Science.gov (United States)

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

Adolescent and adult risk factors for testicular cancer.  

Science.gov (United States)

The incidence of testicular cancer has been increasing over the past several decades in many developed countries. The reasons for the increases are unknown because the risk factors for the disease are poorly understood. Some research suggests that in utero exposures, or those in early childhood, are likely to be important in determining an individual's level of risk. However, other research suggests that exposure to various factors in adolescence and adulthood is also linked to the development of testicular cancer. Of these, two adult occupational exposures-fire fighting and aircraft maintenance--and one environmental exposure (to organochlorine pesticides) are likely to be associated with increased risk of developing testicular cancer. By contrast, seven of the identified factors--diet, types of physical activity, military service, police work as well as exposure to ionizing radiation, electricity and acrylamide--are unlikely to increase the risk of developing testicular cancer. Finally, seven further exposures--to heat, polyvinyl chloride, nonionizing radiation, heavy metals, agricultural work, pesticides and polychlorinated biphenyls as well as marijuana use--require further study to determine their association with testicular cancer.

Testicular cancer: management challenges in an African developing country  

Scientific Electronic Library Online (English)

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

Quercetin prevents docetaxel-induced testicular damage in rats.  

Science.gov (United States)

The protective effect of quercetin on docetaxel - an anticancer agent - induced testicular damage in rats was investigated. Thirty-two rats were randomly divided into four groups: group 1 - control, carrier solutions were given; group 2 - quarcetin 20 mg kg(-1)  day(-1) was given orally; group 3 - docetaxel 5 mg kg(-1) was given intraperitoneally as single dose; group 4 - docetaxel and quarcetin were given together. The histopathological changes; the specific biochemical markers, including antioxidants; and the sperm characteristics were evaluated. Docetaxel caused a significant increase in TBARS level and a significant decrease in SOD, GPX, CAT and GSH levels in the testicular tissues compared with the control group, whereas quercetin led to a significant decrease in lipid peroxidation, which was caused by docetaxel, via reducing TBARS level and increasing the levels of SOD, CAT, GPX and GSH. In addition, after docetaxel administration, sperm motility, sperm concentration, testicular and epididymis weights were significantly decreased and abnormal sperm rate and histopathological changes were increased. However, these effects of docetaxel on sperm parameters, histological changes and the tissue weights were eliminated by quercetin treatment. Our results show that the administration of docetaxel induced the testicular damage (oxidative stress, testes tissue damage and sperm parameters), and quercetin prevented docetaxel-induced testicular damage in rats.

Ultrasonographic findings of torsed testicular appendages in prepubertal children  

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Leydig cell damage after testicular irradiation for lymphoblastic leukemia  

International Nuclear Information System (INIS)

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

Acute testicular pain in children: collaboration in timely management.  

Science.gov (United States)

Acute scrotal pain in a child is a urological emergency. Surgeons should be involved early and exclude torsion promptly, often by surgical exploration. This short report compares the time taken by different medical practitioners [Emergency Department (ED) doctors and surgeons] to assess children presenting to the ED with acute scrotal pain. A retrospective observational study was carried out in a district general hospital ED over a 2-year period. A total of 205 children presented with testicular pain, 48 of whom were clinically diagnosed with torsion in the ED. Surgeons reviewed patients with testicular pain quicker than ED doctors when they were referred directly from triage (P=0.019). Overall, review by a surgeon was more timely if the patient was referred directly from triage rather than after referral by the ED doctor (Pmanagement of patients with testicular pain. PMID:25093896

Intrascrotal involvement of sarcoidosis presenting like testicular appendices.  

Science.gov (United States)

A 31-year-old male visited our clinic with a complaint of painless intrascrotal mass in the left side. He had been diagnosed with pulmonary sarcoidosis 6 years prior. Scrotal ultrasound revealed a distinct mass measuring 18 mm x 16 mm at the left epididymal tail. An epididymectomy was performed for treatment and pathological diagnosis. Four nodules shaped like testicular appendices were also found on the testicular surface and subsequently removed. Histopathological examination established that both the epididymal and appendix-like lesions consisted of non-caseating epithelioid granulomas with giant cells, and were diagnosed as sarcoidosis. The patient has no recurrence of intrascrotal lesions after 6-month follow up. This is the first report of intrascrotal involvement of sarcoidosis presenting like testicular appendices.

An original technique of brachytherapy in the treatment of epidermoid carcinomas of the buccal mucosa  

International Nuclear Information System (INIS)

Purpose: To report our experience using brachytherapy in buccal mucosa carcinoma with particular attention on the technique of implantation used and on the elective treatment to the lymph nodes. Methods and Materials: From 1973 to 1991, 42 patients (36 T1 T2 T3, 35 N0) were treated for epidermoid carcinoma of the buccal mucosa as the first site of head and neck cancer. To study the local control, the group of 36 T1-3 patients was divided into two groups according to the brachytherapy technique used: the parallel wires technique and the loop technique (M. Pernot). The latter consists of making a loop of Iridium wire encircling the tumor, the curved part acting as a barrier for the posterior part of the cheek (site of recurrence). The group of 35 N0 patients was individualized to evaluate the necessity of an elective node treatment. Twenty-three patients had no elective treatment to node areas, 8 an external radiotherapy, and 4 a neck dissection. Results: Overall survival of these 42 patients was 63% at 2 years and 47.5% at 5 years. Specific survival was 77.5% at 2 years and 73.6% at 5 years. Survival without recurrence was 58% at 2 years and 54% at 5 years. Eighty-three percent of the recurrences occurred during the first year. There were six local recurrences on the 14 T1-3 patients treated with the parallel wires technique and 1 on the 22 T1-3 patients treated with the loop technique (6 out of 7 in the posterior part of the buccal mucosa). The local control at 5 yearuccal mucosa). The local control at 5 years was 91% with the loop technique vs. 58% with the parallel wires technique (p = 0.01). Among the 23 N0 patients with no elective treatment, 6 had a nodal failure (5 T2 and 1 T1 of 2 cm). Out of the 8 N0 patients treated by radiotherapy, 3 had a nodal failure. The four N0 patients treated by surgery were controlled. Conclusion: Brachytherapy using the loop technique is the local treatment of choice for tumors ? 5 cm. Elective treatment of the neck lymph nodes is required in patients with a lesion > 1 cm and neck dissection may be preferable to external radiotherapy

Low CYP1A2 activity associated with testicular cancer.  

Science.gov (United States)

The incidence rate of testicular cancer has increased during the last 50 years. An interplay between changing environmental factors and individual susceptibility, e.g. in foreign compound metabolizing enzymes, may have important influences on the risk of testicular cancer. The cytochrome P4501A2 (CYP1A2) enzyme and the bimodally expressed enzyme N-acetyltransferase2 (NAT2) metabolize many procarcinogens/carcinogens. The aim of this population-based case-control study was to investigate if CYP1A2 or NAT2 activity measured as a ratio of urinary metabolites of dietary caffeine is a risk factor in testicular cancer. 378 men participated (80 seminomas, 104 non-seminomas and 194 controls). The CYP1A2 activity was lower in the cases than in the controls [median and 30-70% percentiles: 4.7 (3.9-5.7) and 5.2 (4.4-6.4), respectively]. The subjects were classified in tertiles with low, medium or high CYP1A2 activity. A low CYP1A2 activity was associated with the highest risk of testicular cancer. Including all participants except men using drugs suspected to influence CYP1A2 activity (n = 15), medium and low activity conferred odds ratios (ORs) of 1.54 [confidence intervals of 95% (CI(95%)) 0.93-2.55] and 2.11; CI(95%) (1.23-3.62), respectively, of having testicular cancer. Excluding smokers (n = 157) the ORs of medium and low activity were 3.63; CI(95%) (1.53-8.60) and 4.70; CI(95%) (2.03-10.89), respectively. After further exclusion of cases that had received chemotherapy or radiation (n = 47), similar significant results were achieved. In the groups with the lowest CYP1A2 activity the ORs for seminoma and non-seminoma were 2.12; CI(95%) (0.93-4.81) and 2.10; CI(95%) (1.02-4.32). The phenotype of NAT2 was not associated with testicular cancer. In conclusion, we found no association of NAT2 phenotype to testicular cancer, whereas significant associations between CYP1A2 activity and testicular cancer were shown. PMID:14976127

Radionuclide diagnostics of testicular blood flow changes in varicocele  

International Nuclear Information System (INIS)

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

Gynecomastia Following Cytotoxic Therapy in a Patient with Testicular Cancer  

Directory of Open Access Journals (Sweden)

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

The objective was to study the normal testicular parameter and morphological changes during epididymal transit in the epididymis of white Fulani b [...] ulls. It was observed that there was reduction in the proportion of spermatozoa carrying the proximal cytoplasmic droplet (PCD) along the epididymis as spermatozoa mature. There were more narrow head in the left (0.40) than the right epididymis (0.10). There was more bent normal tail (16.7) in the left epididymis than in right epididymis (13.0). The sperm cells having looped tails are higher in the left epididymis (caput, 4.90; corpus, 5.30; caudal 4.30) than the right epididymis (caput, 4.70; corpus, 3.20; caudal 5.10) despite the fact that the caudal epididymis in the right epididymis has a higher mean value. In this study the left testicle had more of the morphologically defective spermatozoa (12.96%) than the right testicles (12.42%). The epididymal and testicular parameters were positively correlated (weight of epididymis, weight of estis and epididymis, length of epididymis, circumference of the testes and epididymis, (p

Primary Testicular Carcinoid Tumor presenting as Carcinoid Heart Disease.  

Science.gov (United States)

Primary carcinoid tumors of the testis are very rare, and they seldom present with carcinoid syndrome. We report a hereto unreported instance, where a patient with a long-standing testicular mass presented with carcinoid heart disease, an uncommon form of carcinoid syndrome. He presented with symptoms of right heart failure, episodic facial flushing and was found to have severe right-sided valvular heart disease. His urinary 5-hydroxy indole acetic acid level was elevated. He underwent orchidectomy and the histopathology confirmed a testicular carcinoid tumor. PMID:25624579
