Quiste epidermoide testicular / Testicular epidermoid cyst  

Scientific Electronic Library Online (English)

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

Quiste epidermoide testicular / Testicular epidermoid cyst  

Scientific Electronic Library Online (English)

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

Quiste epidermoide gigante intertesticular / Giant intertesticular epidermoid cyst  

Scientific Electronic Library Online (English)

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

En un 25% tienen una localización intradiploica y excepcionalmente infratentorial. Presentamos un caso clínico poco frecuente de un quiste epidermoide intradipl [...] oico gigante infratentorial. El paciente consultó por una diplopia y un síndrome cerebeloso. La tomografía computarizada y la resonancia magnética mostraron una lesión gigante lítica extradural de la fosa posterior de 5,2 cm x 3,8 cm, con realce periférico con el contraste. Utilizamos un abordaje suboccipital retrosigmoideo para realizar una exéresis completa tumoral y una resección incompleta capsular, debido a la adherencia de ésta al seno lateral. La evolución posoperatoria fue favorable. Realizamos una revisión bibliográfica de la literatura y discusión de nuestro caso. Abstract in english Epidermoid cysts are benign, uncommon lesions (1% of all intracranial tumors). Their localization is intradiploic in 25% of cases, and exceptionally subtentorial. We report here a rare case of giant intradiploic infratentorial epidermoid cyst. A 74-year old patient presented with recent diplopia and [...] sindrome cerebellar. CT scan and MR imaging revealed a giant osteolytic extradural lesion of the posterior fossa (5,2 cm x 3,8 cm) with a small area of peripheral enhancement after contrast injection. Retrosigmoid suboccipital craniectomy allowed a satisfactory removal of the tumor, followed by an acrylic cranioplasty. The outcome was good. Neuropathological examination confirmed an epidermoid cyst. We review the literature and discuss our case.

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.

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

Epidermoid cyst of the testis: a case report  

International Nuclear Information System (INIS)

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

Iatrogenic intraspinal epidermoid cyst.  

Science.gov (United States)

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  

Energy Technology Data Exchange (ETDEWEB)

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.

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Objetivo: La microlitiasis testicular (MT), que se caracteriza por la existencia de microcalcificaciones dentro de los túbulos seminíferos, es poco frecuente y generalmente constituye un hallazgo incidental durante la realización de la ecografía escrotal. Método: Presentamos un caso de un varón de 4 [...] 5 años de edad, sin factores de riesgo para el desarrollo de un tumor testicular de células germinales, diagnosticado de una microlitiasis testicular bilateral. Resultados: El paciente ha sido sometido a control evolutivo anual con ecografía testicular, sin desarrollar un tumor germinal durante un seguimiento de 4 años. Conclusiones: Aunque el significado clínico de la MT está en debate debido a las diferentes controversias halladas en la literatura sobre su asociación o no con el tumor testicular, así como los diferentes protocolos de manejo inicial y de los intervalos adecuados para su vigilancia y seguimiento, parece razonable realizar un control ecográfico anual, independientemente de la existencia o no de factores de riesgo asociados. Abstract in english Objectives: Testicular microlithiasis,characterized by the existence of microscopic calcifications within the seminiferous tubules, is rare, generally anincidental finding during a scrotal ultrasound.

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

It involves a 37 year old male seeking medical care on feeling a painful growth in his right testicle after being hit by a ball. [...] On examination, a hard, stony nodule can be felt in the right testicle, with deep layer adherence. On referral to urology, and after ultrasound confirmation of the growth, a radical orchiectomy is performed. The histopathological diagnosis is for classic seminoma with an intense sarcoid reaction, extending to the coverings of the testis, epididymis and to the proximal portion of the cord.

[Orbital epidermoid cyst. Case report].  

Science.gov (United States)

Epidermoid tumors represent 1% of all primary intracranial tumors. Most of them occur intradurally in cerebellopontine angle and parasellar citerns. The intra-orbital location accounts for 4 to 5% of all primary intra-orbital tumors. We report the case of a 23-year-old girl with progressive right proptosis who had developed 6 months earlier. The tumor was removed via an external orbitotomy approach. Histology confirmed the diagnosis. PMID:17916370

Testicular tumors  

International Nuclear Information System (INIS)

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

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

Suprasellar epidermoid presenting with precocious puberty  

Directory of Open Access Journals (Sweden)

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

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.

Orbital dermoid and epidermoid cysts: Case study  

Directory of Open Access Journals (Sweden)

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

Testicular Germ Cell Cancer  

Science.gov (United States)

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

DWI Findings in an Iatrogenic Lumbar Epidermoid Cyst  

Science.gov (United States)

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

Epidermoid Cyst of Maxilla- Rare and interesting Case Report  

Directory of Open Access Journals (Sweden)

Full Text Available Epidermoid cyst, a variant of dermoid cyst, is a benign lesion of epithelial origin, in which the cystic cavity is lined by epithelium without skin appendages. The head and neck sites most commonly affected with cutaneous cysts include the scalp (34%, neck (18%, periorbital area (17%, cheeks (including lips-16%, periauricular area (9%, and nasal area (including forehead-6%. Although a common cutaneous presentation in the head and neck region, epidermoid cysts of the maxillary sinus is an extremely rare occurrence. We report a case of epidermoid cyst of the maxillary sinus. The lesion being rare and asymptomatic often presents a diagnostic dilemma for the clinician.

Intrarenal epidermoid cyst presented as an enlarged multicystic kidney  

Directory of Open Access Journals (Sweden)

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

Testicular scintigraphy; Hodenszintigrafie  

Energy Technology Data Exchange (ETDEWEB)

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

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

Quiste óseo aneurismático / Aneurysmal bone cyst  

Scientific Electronic Library Online (English)

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

Primary testicular leiomyosarcoma.  

Science.gov (United States)

Primary testicular leiomyosarcoma is an extremely rare tumor, and, to the best of our knowledge, only 20 cases in adults have been reported in the literature to date. Herein, we present a case of a 68-year-old man who complained of left scrotal swelling for 2 months. Radiological examination revealed a left testicular tumor with no metastases to other organs. A left inguinal orchiectomy was carried out and histopathologic examination revealed an intratesticular leiomyosarcoma. The patient was treated successfully by orchiectomy and received no adjuvant therapy. During follow up until 12 months after surgery, there has been no recurrence or metastases of the disease.

Epidermoid carcinomas of the conjunctive with intraorbital and intraocular invasion  

International Nuclear Information System (INIS)

The epidermoid carcinomas of the conjunctive are tumors in general of low incidence with a range between 0.13 and 1.9 cases for 100,000 inhabitants; this incidence is superior however in tropical countries. The incidences reported for intra orbital and intraocular invasive forms have a range between 2 and 12% which demonstrates the aggressive character of this tumor. The handling of epidermoid carcinoma of the conjunctive in initial stages is very conservative, but in their natural history this tumor can invade the ocular globe, orbit, neighboring regions and distant organs, thereby of importance an early diagnosis and an appropriate treatment. Our objective was to know the incidence of epidermoid carcinoma of the conjunctiva with intraocular and intra orbital invasion in the Havana National Oncology Institute. We carry out a retrospective and descriptive study of 18 patients with clinical diagnoses and histology of epidermoid carcinoma of the conjunctiva with orbit infiltration assisted from January of 1995 until December 2003 classified as T4 NO MO. The evaluated parameters were: age, sex, initial treatment and evolution. Middle aged of our serie it was 58.7 years, excisional surgery and deep radiotherapy was the initial treatment applied in 83.33% of the cases. In its evolution eight cases (44.44%) of the patients had unfavorable result and radical surgery was carried out in 50% of the patients. (The author)

Testicular Cancer and Cryptorchidism  

Directory of Open Access Journals (Sweden)

Full Text Available The failure of testicular descent or cryptorchidism is the most common defect in newborn boys. The descent of the testes during development is controlled by insulin-like 3 peptide and steroid hormones produced in testicular Leydig cells, as well as by various genetic and developmental factors. While in some cases the association with genetic abnormalities and environmental causes has been shown, the etiology of cryptorchidism remains uncertain. Cryptorchidism is an established risk factor for infertility and testicular germ cell tumors (TGCT. Experimental animal models suggest a causative role for an abnormal testicular position on the disruption of spermatogenesis however the link between cryptorchidism and TGCT is less clear. The most common type of TGCT in cryptorchid testes is seminoma, believed to be derived from pluripotent prenatal germ cells. Recent studies have shown that seminoma cells and their precursor carcinoma in situ cells express a number of spermatogonial stem cell (SSC markers suggesting that TGCTs might originate from adult stem cells. We review here the data on changes in the SSC somatic cell niche observed in cryptorchid testes of mouse models and in human patients. We propose that the misregulation of growth factors' expression may alter the balance between SSC self-renewal and differentiation and shift stem cells towards neoplastic transformation.

Antegrade testicular vein phlebography and funicular lymphography in testicular tumors  

International Nuclear Information System (INIS)

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

Testicular torsion: Case report  

Directory of Open Access Journals (Sweden)

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

Transverse testicular ectopia.  

Science.gov (United States)

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

It is often clinically indistinguishable from lesions such as testicular tumour and infarction and may even mimic testicular torsion. Men aged 20-50 years old are most commonly affected and often pr [...] esent with painful or painless enlargement of the scrotum. Ultrasound (US) is currently the best technique for imaging the scrotum and its contents and for diagnosing testicular lesions. We present the case of a 58 year-old male, followed in pneumology for pulmonary tuberculosis, who complained of pain and right scrotum enlargement in the second month of anti-tuberculosis chemotherapy. First assessment, seconded by US, suggested a neoplasic lesion, and the final diagnosis revealed testicular tuberculosis.

Stage 1 testicular seminoma  

International Nuclear Information System (INIS)

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

Depressive symptomatology and pineal epidermoid cyst: a case report.  

Science.gov (United States)

Introduction Intracranial epidermoid cysts are congenital cysts. They comprise 0.2-1.8% of primary intracranial tumours and are four to nine times as common as dermoid cysts. Case report We here in present the case of a 32-year-old man who reported sudden onset of symptoms of a depressive symptomatology and particularly severe headache, accompanied by fatigue, depressed mood most of the day, marked diminished interest or pleasure in all or almost all activities, insomnia and diminished ability to think or concentrate. Brain magnetic resolution imaging examination revealed a pineal epidermoid cystic lesion, visualised in the posterior part of the third ventricle, with a maximum diameter of ?2.8 cm and obstructing the aqueduct of Sylvius, causing obstructive hydrocephalus. Discussion Pineal cysts may enlarge over time, because of either increased cyst fluid or intracystic haemorrhage, and become symptomatic. Brain radiological investigations in patients with depressive symptomatology may be substantial. PMID:25287638

[Congenital epidermoid tumors of the temporal bone. 1: Pathogenesis].  

Science.gov (United States)

Epidermoids (congenital cholesteatomas) of the mastoid air cells lying behind an intact tympanic membrane are not as rare as previously supposed. We discuss the current hypotheses of their pathogenesis critically, and favour the hypothesis of germ scattering. We summarize some not so well known details of the early stages of development of the normal involution of the first branchial cleft and of the first pharyngeal pouch as well as the subsequent development of the external meatus, the tubotympanic recess and the pneumatized spaces of the temporal bone. On this basis the transfer of ectodermal cells to the entoderm, the subsequent transmission from the embryonal closing membrane to the definite pneumatic spaces of the middle ear, and the variable frequency of recurrence of epidermoids in these diverse spaces are explained.

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

Carcinoma en quiste tirogloso / Carcinoma in thyroglosal duct cyst  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish El carcinoma diferenciado de tiroides en quiste tirogloso (CaQT) es una rara entidad. En diferentes series de pacientes operados por quistes tiroglosos su incidencia fue del 0.7 al 1.07%. Luego de la extirpación del quiste por el procedimiento de Sistrunk, no hay consenso sobre la indicación de tiro [...] idectomía total, radioablación y/o terapéutica supresiva con levotiroxina. El objetivo del Departamento de tiroides de SAEM, fue evaluar: formas de presentación, evolución clínica, métodos diagnósticos de utilidad y tratamiento para consensuar futuras conductas. Material y Métodos: Estudio multicéntrico, retrospectivo en 22 pacientes entre 10 a 69 años, 15 mujeres y 7 varones. Resultados: El tamaño de los quistes osciló entre 1 y 8 cm (Mediana= 3.0 cm, ? ± DS= 3.7 ± 2.2 cm). La mitad de los pacientes presentó crecimiento del quiste en los 6 meses previos a la cirugía. La punción resultó sospechosa en 2/5 quistes y positiva en uno. La ecografía tiroidea evidenció nódulos en 4/13 casos (30%). Se realizó tiroidectomía en 17/22 pacientes (total: 15 y subtotal: 2). La histología del CaQT demostró carcinoma papilar en 21 y carcinoma folicular en uno. Hubo coexistencia de cáncer intratiroideo en el 23.5% de los casos, ninguno multicéntrico. Dos pacientes presentaron metástasis ganglionares y otro tuvo compromiso muscular (ninguno de ellos coexistió con cáncer intratiroideo). Se radioablacionó a 13 pacientes. En 9/11 pacientes la tiroglobulina permaneció indetectable durante el seguimiento (1 a 14 años). Conclusiones: 1) Realizar ecografía de cuello y punción ecoguiada a todo paciente con quiste tirogloso. 2) En caso de CaQT combinar simultáneamente tiroidectomía total y procedimiento de Sistrunk. 3) Evaluar radioablación complementaria y tratamiento supresivo con levotiroxina en cada caso. 4) Efectuar el seguimiento tal como en los carcinomas ortotópicos.

OBJECTIVE: to e [...] valuate several and controversial aspects in the largest series of DTC in TGDC reported in the literature. Subjects and methods: retrospective multicentric study: n= 22, aged 10-69 yrs. (15 females and 7 men) who underwent the Sistrunk procedure for TGDC. Results: none of the TGDC was less than 1 cm (median 3.0 cm, ?±SD= 3.7 ± 2.2cm). In half of them there was an increased cystic size in the last 6 months before surgery. Cyst FNA was suspicious in 2/5 and positive in one, whereas the histological diagnosis of the operated TGCD was papillary cancer in 21 and 1 follicular carcinoma. Thyroid ultrasound (US) (n=13) showed nodules in 30% of the cases. Tx was performed in 17/22 (total: 15, subtotal: 2). Thyroid DTC coexisted in 4/17 (23.5%), and was unilateral in all of them. Lymph node metastases were present in 2 adults and muscle involvement was found in the 10-year old girl. None of these 3 patients had overt thyroid lesions. 131-I therapy was performed in 10 patients. In 9 out of 11 subjects Tg remained undetectable during follow-up (1-14yrs.). Persistent high Tg was present in one case without thyroid DTC. Conclusions: 1) Ultrasonography and FNAB should be performed to every patient with thyroglossal duct cyst 2) In case of TGDC, total Tx and Sistrunk's procedure should be simultaneously combined 3) 131-I therapy and L-T4 suppressive treatment should be evaluated in every case 4) Follow-up as in the DTC.

Sublingual Epidermoid Cyst Presenting with Distinctive Magnetic Resonance Imaging Findings  

Science.gov (United States)

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

Testicular Teratoma in an Infant: Case Report  

International Nuclear Information System (INIS)

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

Studies of testicular function after treatment for testicular tumor, 1  

International Nuclear Information System (INIS)

Recently, the treatment for testicular tumor has improved. Preservation of testicular function in the treatment of testicular tumor is important, because the majority of the patients are young. We investigated the testicular function of patients with testicular tumor before, during and after treatment. As a part of this study, the fertility of patients with testicular tumor before and after treatment was evaluated. 1. Fourteen of 78 married patients (18 %) showed sterility for two or more years before treatment. 2. When semen was examined in 31 patients before treatment, only seven patients (23 %) showed normal sperm counts of more than 40 x 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.

It must be suspected in healthy patients living in endemic areas and who show a sudden pattern of vascular collapse. These patients rarely have a previous record of hydatic cysts, but their clinical history usually shows the existence of a previous record of non-filiated allergic processes.

Tratamiento del quiste sinovial con infiltración de metilprednisolona  

Directory of Open Access Journals (Sweden)

Full Text Available El quiste sinovial es el tumor más frecuente de la mano. Existen varias formas de tratamiento como la multipunción, ruptura, excisión y aspiración. La excisión es el tratamiento más utilizado. La frecuencia de recidiva es alta con cualquier método. Autores como Varley,5 Nield,7 Esteban8 y Holm13 proponen infiltrar metilprednisolona como alternativa terapéutica. Para identificar la frecuencia de recidiva después de la aspiración e infiltración de metilprednisolona se estudiaron los pacientes enviados al módulo de cirugía ambulatoria del Hospital General de Zona Número 2 (HGZ 2 del Instituto Mexicano del Seguro Social (IMSS en Cárdenas, Tabasco; de febrero de 1999 a enero del 2000. Bajo anestesia local se aspiró el contenido del quiste y se aplicaron 20 mg de metilprednisolona. Se inmovilizó con vendaje durante una semana. El paciente continuó vigilancia con su médico familiar con cita abierta a cirugía en caso de recidiva. Se trataron 69 casos presentándose 12 recidivas (17.3% que fueron programados para intervención quirúrgica. Este tratamiento es una alternativa terapéutica de bajo costo y se propone como una opción de tamizaje para el tratamiento quirúrgico el cual tiene alto costo y riesgo de secuelas.

Epidermoid cyst of the brain in the horse.  

Science.gov (United States)

An aged Connemara mare had a neurological illness lasting 3 weeks and characterised by episodes of dullness, head-pressing, staggering gait and hyperexcitability. The signs recurred at intervals of 3 to 4 days, with intervening periods of apparent normality. Post-mortem examination revealed an epidermoid cyst on the dorsal surface of the occipital lobe of the left cerebral hemisphere. The cyst was lined by stratified squamous epithelium and contained desquamated keratinised material and blood. The lesion is considered to be a congenital malformation which enlarges and produces space-occupying signs. PMID:954719

Abordaje endoscópico de los quistes gliales pineales sintomaticos  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish Objetivo. Los quistes gliales pineales (QGP) son infrecuentes. El manejo quirúrgico de estos quistes no está consensuado. En la literatura se recogen 18 casos tratados por vía endoscópica. El objetivo de este trabajo es contribuir con nuestra experiencia en el tratamiento endoscópico de los QGP. Mat [...] erial y método. Entre 1999 y 2004, cinco pacientes con QGP sintomáticos, con o sin hidrocefalia, se trataron mediante vintriculostomía premamilar endoscópica (VPE) y fenestración del quiste. Se utilizó un endoscopio rígido, con sistema de neuronavegación en los casos sin hidrocefalia. Resultados. En el período de seguimiento (de 6 meses a 4 años) se recoge una resolución clínica en 4 casos y una disminución del tamaño del quiste en todos los casos. Todas las VPE fueron permeables en el seguimiento. No hubo déficits clínicos permanentes en ningún caso. Discusión. No existe en la literatura un acuerdo en el mejor tratamiento quirúrgico de los QGP. A pesar de la gran aceptación de la vía endoscópica, un gran número de autores abogan por una cirugía abierta o por una cirugía extereotáxica como la mejor opción. Además, existen algunas diferencias en el manejo quirúrgico endoscópico según ofrece la literatura. Conclusión. La VPE con la fenestración del quiste es un tratamiento eficiente debido a la baja morbilidad y a la eficacia en la resolución clínica y radiológica de los QGP con o sin hidrocefalia. La cirugía abierta, especialmente con la ayuda endoscópica, podría ser un tratamietno de segunda elección, y la cirugía estereotáxica debería abandonarse en estos casos. Abstract in english Objetive.

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

Testicular microlithiasis in paediatric age  

International Nuclear Information System (INIS)

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

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 sequelae 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.

Isodense epidermoid cyst in the pineal region. Case report  

Energy Technology Data Exchange (ETDEWEB)

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

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.

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.

Anatomico-radiological study of intraosseous epidermoid cysts  

International Nuclear Information System (INIS)

Anatomico-radiological study of 8 cases of intraosseous epidermoid cysts (1 in the skull, 6 in distal phalanges of the hand, 1 in distal phalanx of the foot with invasion of the adjacent joint). The epithelium was malpighian with hyperkeratosis (therefore the scales filled the cavity), sometimes with parakeratosis and even dyskeratosis but without signs of malignancy. The adjacent connective tissue and bone reactions were more active in the phalanx than in the skull and this could explain the frequent pain in the phalanges. The bone remodelling explains the radiological pictures and sustains the differential diagnosis. In 5 out of the 8 cases (particularly in the skull) a history of previous local trauma was present. However, the etiological importance of trauma should be discussed with respect to that of dysembryoplasia. (orig.)

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.)

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

Energy Technology Data Exchange (ETDEWEB)

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

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

Nine patients (13,8 % had undergone surgery before. Cervical tumour was found in 54 patients and fistula in 6. The Sistrunk's surgical technique was used in 62 patients (95,4 %, where as in the rest it was used the simple exeresis of the cyst. Operative mortality was null. Three patients (4,6 % presented incision sepsis. The minimun follow-up lasted one year. Two patients relapsed and were operated on again 10 months later. This affection is relatively frequent with predominance in the first decades of life. An adequate therapeutics leads to the resolution of it with no mortality

MÉTODO: describimos el caso de un varón de mediana edad que consulta por hematospermia monosintomática de larga evolución. Al tacto rectal presentaba una próstata adenomatosa no sospechosa. Se practicó ecografía transr [...] ectal que revela quiste de utrículo complicado. RESULTADOS: Se realizó marsupialización endoscópica del quiste, consiguiendo remisión total de la hematospermia. CONCLUSIONES: Se debe realizar ecografía transrectal a todos los pacientes que consultan por hematospermia de larga evolución, indicando la marsupialización endoscópica del quiste del conducto mülleriano en aquellos pacientes sintomáticos y con quistes complejos observados en la exploración ecográfica, obteniendo un importante porcentaje de cura o mejoría en este grupo de pacientes sin inducir ningún efecto colateral secundario. Abstract in english OBJECTIVES: To report one case of utriculum cyst treated endoscopically. METHODS: We describe the case of a mid-age male patient consulting for long-term monosymptomatic hemospermia. Rectal digital examination revealed a non suspicious adenomatous prostate. Transrectal ultrasound showed a complicate [...] d utriculum cyst. RESULTS: Endoscopical marsupialization of the cyst was performed with complete remission of hemospermia. CONCLUSIONS: Transrectal ultrasound should be performed in all patients presenting with long-term hemospermia. Endoscopical marsupialization of the mullerian duct cyst is indicated in symptomatic patients or those with complex cysts on ultrasound, offering a high cure/improvement rate in this group of patients without secondary effects.

The patients was treated with non-steroidal anti-inflammatories and methotrexate. In spite of this, the inflammatory articular activity was maintained at the level of the carpus and knees and there was a volume increase in the posterior region of both legs, with spontaneous pain and positive Homan´s sign. At first, it was evaluated the possibility of a thrombophlebitis of the popliteal region, but, finally, it was considered as a Baker´s cyst.

Testicular Manifestation of a Transformed Mycosis Fungoides  

Science.gov (United States)

Testicular neoplasms occur in more than 90% of cases, due to primary testicular germ cell tumors. Other entities are non germ cell tumors of the testis, testicular manifestation of lymphomas or metastases. International and interdisciplinary co-operation has led to the development of urological guidelines and to good therapeutic success for testicular neoplasms. The gold standard for treatment of a testicular neoplasm is the radical orchiectomy. However, for individual cases with suspected lymphoma, a treatment decision differing from the guidelines may be reasonable. We present the case of a 38-year-old man with testicular manifestation of a transformed mycosis fungoides, which is the most common form of cutaneous T-cell lymphoma. PMID:24711905

The diagnosis of epidermoids of the cerebellopontine angle with balanced fast field echo  

International Nuclear Information System (INIS)

Objective: To assess the clinical value of balanced fast field echo (B-FFE) in the detection for epidermoids of the cerebellopontine angle. Methods: The findings of conventional magnetic resonance imaging and B-FFE imaging in 8 cases with epidermoid of the cerebellopontine angle were retrospectively analyzed. The diagnosis was proved by operation and pathology. Results: In seven of the eight cases, the epidermoids exhibited signal intensities relatively similar to CFS on conventional T1- and T2- weighted MR images. The remaining case showed iso intensity on either T1- or T2- weighted MR images, which was almost neglected. All of the eight cases showed heterogeneous signal characteristics on B-FFE, which were quite different from the signal of CFS. Meanwhile, B-FFE also produced clearly the tissue contrast of trigeminus embedded in the epidermoids of the cerebellopontine angle. Conclusion: B-FFE is an efficient and fast technique for diagnosing the epidermoid of the cerebellopontine angle. It can also provide precise preoperative information about the trigeminus encasement.

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

Middle cranial fossa epidermoid cyst: a case report of unusual CT and MR findings  

Energy Technology Data Exchange (ETDEWEB)

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

Full Text Available SciELO Venezuela | Language: Spanish Abstract in spanish El cáncer esofágico es una neoplasia gastrointestinal con un insidioso curso y pobre pronostico. La enfermedad afecta predominantemente a personas de edad avanzada con un pico de incidencia entre los 60 y 70 años. Desafortunadamente, muchos síntomas experimentados por los pacientes ocurren en estadi [...] os avanzados de la enfermedad, lo cual resulta en un mal pronóstico. La diseminación más común es en sentido ascendente por extensión en la mucosa y fácilmente se extiende a través de la pared esofágica a estructuras adyacentes, debido a la ausencia de serosa. Las mayores complicaciones son atribuidas a la obstrucción luminal y la invasión local. Presentamos un caso de un paciente de 69 años de edad. La endoscopia digestiva superior evidenció dos lesiones separadas en esófago distal y fundus gástrico. Los cambios histológicos determinaron que ambas lesiones eran carcinoma epidermoide. Abstract in english Esophageal cancer is a gastrointestinal malignancy with an insidious onset and a poor prognosis. The disease predominantly affects the elderly with a peak incidence among those between 60 and 70 years of age. Unfortunately, many of the symptoms experienced by patients with esophageal cancer occur la [...] te in the course of the disease, at which time it is already at an advanced stage, resulting in a very poor prognosis. The most common dissemination is in an ascending path through mucosal extension; extending easily through the thin esophageal wall due to the absence of a serosa to invade adjacent structures. Most complications due to esophageal cancer are attributed to luminal obstruction and local invasion. A case of a 69-year-old male patient is presented. Upper digestive endoscopy showed two separated lesions at the distal esophagus and gastric fundus. Histological changes showed both lesions were squamous cell carcinomas.

Cerebellopontine angle epidermoid showing a positive enhancement upon metrizamide CT cisternography  

International Nuclear Information System (INIS)

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

Paraurethral cyst. A case report Quiste parauretral. Presentación de un caso  

Directory of Open Access Journals (Sweden)

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

Familial testicular cancer and developmental anomalies  

International Nuclear Information System (INIS)

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

Radiation Therapy of Testicular Seminoma  

International Nuclear Information System (INIS)

Purpose: Testicular seminomas are radiosensitive and adjuvant radiation therapy after orchiectomy results in long term survival in early stage diseases. Ten year results of radiation therapy after orchiectomy and results of definitive treatment of recurrent seminoma are presented. Materials and Methods: Between August 1980 and February 1990, 32 patients with testicular seminomas were treated at the Department of Therapeutic Radiology, Seoul National University Hospital. Twenty-seven patients received radiation therapy after orchiectomy and 5 patients for treatment of recurrent tumors. Two of postoperatively treated patients and 2 of recurrent patients were excluded from the study because of incomplete treatment. Of the patients treated postoperatively. 18 were stage I, 5 were stage IIA, one was stage IIB, and one was stage IIC. There were 4 ipsilateral and 2 contralateral cryptorchids. Preoperatively, b-HCG levels were elevated in 5 patients. Median dose to pelvic and paraaortic lymph node area was 2900 cGy (1550-4550 cGy). One patient with stage I, 4 with stage IIA, and 1 with stage IIB received prophylactic mediastinal irradiation. Two patients were treated with chemotherapy before radiation therapy. Median follow-up period was 104(3-144) months. Result: Local control rates were 100% at 5 years after orchiectomy. Five year survival rates were 94.4% in Stage I and 100% in Stage II patients. One patient with stage I disease died 3 months after surgery due to mediastinal metastasis. All the 3 patients treated for recurrent disease are alive without disease. Conclusion: Postorchiectomy radiation to the pelvis and para-aortic area remains the treatment of choice for patient with early stage testicular seminoma. Radiation therapy is also an excellent treatment modality for recurrent seminoma

Radiation therapy of testicular tumors  

International Nuclear Information System (INIS)

Radiation therapy of seminoma is clearly defined and the results are extremely good. On the other hand radiation therapy of other testicular tumors still is not fully accepted. Excellent results of therapeutical treatment are always challenge for further improvment of therapeutical techniques and reduction of side effects. Best radiation therapy, which is taking into account size of tumor and metastases can produce for 95% of seminoma patients more than 5 years survival. For teratoid carcinoma radiation therapy is used succesfully combined with chemotherapy. (orig.)

Microsurgical treatment of spinal epidermoid and dermoid cysts in the lumbosacral region.  

Science.gov (United States)

The aim of this study was to evaluate the characteristics and surgical outcome of spinal epidermoid and dermoid cysts in the lumbosacral spine. We reviewed 26 patients with spinal epidermoid and dermoid cysts (15 epidermoid and 11 dermoid) treated between October 2000 and December 2010. The latter 15 patients of this series underwent neurophysiological monitoring during surgery. Gross total resection of the tumour was achieved in 46.2% of patients, and 53.8% underwent subtotal resection. In 14 patients, the tumour capsule adhered so tightly to the neural structures that a section of the capsule remained in situ. After surgery, the Japanese Orthopaedic Association score improved in 80.8% of patients, remained stable in 15.4%, and declined in 3.8%. The average follow-up period was 53 months. Three patients developed recurrence of the tumour and 20 patients resumed a normal working life. Microsurgical techniques and intraoperative neurophysiological monitoring are practical and reliable methods for radical removal of spinal epidermoid and dermoid cysts that involve the conus medullaris and cauda equina.

[Verification of testicular cancer guidelines].  

Science.gov (United States)

Testicular cancer is a rare disease that affects 1-2 in 100,000 people in Japan ; however, it is a very significant disease in that it has a high prevalence amongst young adults aged in their 20s and 30s and it brings about metastasis from a relatively early stage. The 2009 edition of the Testicular Cancer Clinical Practice Guidelines sets out a detailed summary of 32 clinical questions (CQ) considered necessary in routine clinical practice across the fields of epidemiology, diagnosis, treatment, etc, in the form of recommendations and commentary. These CQs are considered extremely important in understanding the foundation of future testicular cancer treatment guidelines. In this symposium, five doctors gave lectures consisting of the following contents in which they validated the guidelines and gave concrete clinical practice examples through cases they had experienced themselves with regards to the treatment strategies for (1) stage I patients, (2) patients with advanced cancer and (3) patients with extragonadal germ cell tumors. (1) Stage I patients : In seminoma cases, the doctors focused on the relapse prevention effect provided by single-agent carboplatin adjuvant chemotherapy. In non-seminoma cases, treatment options were considered according to risk based on the presence or absence of vascular invasion, a prognostic factor. (2) Patients with advanced cancer : 30% of testicular cancers are metastatic and progress to advanced cancer. In refractory cases resistant to bleomycin, etoposide and cisplatin therapy, etoposide ifosfamide, and cisplatin therapy and vinblastine, ifosfamide and cisplatin therapy have been used, but without satisfactory results and the development of new salvage chemotherapy is an important issue. The therapeutic strategies against advanced testicular cancer were narrowed down to (2) -1) therapeutic effects from ultra-high-dose chemotherapy, (2) -2) salvage chemotherapy in cases where residual tumors are observed in induction chemotherapy and (2) -3) minimally invasive surgical treatment for residual tumors after chemotherapy. Concrete clinical cases from basic treatment strategies to the latest findings in refractory cancer patients were presented and considered in detail. (3) Patients with extragonadal germ cell tumors : Extragonadal germ cell tumors account for less than 5% of all germ cell tumors, but they can be cured with multimodality therapy. Therefore, it is important to reach an accurate diagnosis and provide the correct treatment. This disease is suspected in patients with elevated ?-fetoprotein and human chorionic gonadotropin without the appearance of tumors in the testes, and tumors can be observed on the center line of the body such as the mediastinum or retroperitoneum. Traditionally, computed tomography-guided biopsy has been carried out in diagnosis. However, new techniques such as endoscopic ultrasound-guided biopsy have also been reported in recent years and the latest information, including treatments, was presented at this symposium.

Testicular cytotoxicity of intravenous procarbazine in rats.  

Science.gov (United States)

Although the testicular cytotoxicity of procarbazine has been evaluated in the rat, previous models have utilized routes other than the intravenous one, and have generally employed multiple-dose regimens. In this report, we describe testicular toxicity in the Sprague-Dawley rat following a single intravenous bolus of procarbazine (0-700 mg kg body weight), with necropsy 59 +/- 2 days later. Testicular toxicity was evaluated qualitatively by histology and quantitatively by testicular weight, sperm head count, repopulation index and epididymal index. Effects of procarbazine on heart, lung, liver and kidney histology were evaluated qualitatively. Progressive dose-dependent testicular atrophy and oligospermia occurred at low and intermediate dosages of procarbazine. Marked testicular atrophy, oligospermia and germinal hypoplasia were observed at high dosages (500 and 700 mg kg-1 body weight). LD50 at day 59 for procarbazine appears to be approximately 600 mg kg-1 body weight using this regimen. This model will facilitate the study of techniques to avoid drug-induced testicular damage.

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)

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

Petrous bone epidermoid cyst caused by penetrating injury to the external ear: Case report and review of literature  

Science.gov (United States)

Epidermoid cysts are histologically benign, slow-growing congenital neoplasms of the central nervous system that may arise from retained ectodermal implants. The epidermoid lesions are generally caused during the 3rd to 5th week of gestation by an incomplete cleavage of the neural tissue from the cutaneous ectoderm, though it can also happen later in life due to introduction of skin elements by skin puncture, trauma or surgery. We present this unique case of a petromastoid epidermoid cyst associated with ipsilateral cerebellar abscesses, presenting 20 years after a penetrating trauma to the external auditory canal. Radical excision of both lesions and revision of the previous fistulous tract was performed. We present the diagnostic challenge and the operative treatment of this unique case, which to our knowledge is the first where an epidermoid cyst and an adjacent brain abscess occurred as a result of a single traumatic event.

On the physical exam, a pedicled, consistent, smooth surface 1.5 x 1 cm lesion, similar in color to the adjacent mucosa, [...] was found. The lesion was surgically removed and the microscopic exam showed mucosal fragments with pedicled lesion; the cystic cavity sometimes lined with pseudostratified cylindrical epithelium and others with stratified squamous flat interface of the epithelium. Around the cyst, a well-delimited mass of lymphoid tissue, presenting lymphoid follicles, was also seen. Lymphoepithelial cyst has clinical characteristics similar to those of others lesions that occur in the oral cavity. The diagnosis should be based on conservative biopsy, with total removal of lesion.

Quiste del colédoco como causa de dolor abdominal: revisión de un caso y bibliografía  

Directory of Open Access Journals (Sweden)

Full Text Available El quiste del colédoco se define como la dilatación congénita o combinada del árbol biliar extrahepático (tipo más frecuente o intrahepático. La etiología no está aún determinada, pero existen tres teorías. Esta patología se observa en niños y adultos, predominantemente en mujeres. Pueden manifestarse anomalías en todo el sistema biliar, ya sea intra o extrahepático. Se clasifica en 5 tipos. Antes, el abordaje de dichos quistes era la cistoentero anastomosis, pero ahora se recomienda realizar una escisión completa del quiste, para disminuir el riesgo de malignidad y desarrollo de colangitis o pancreatitis recurrente. Aquí se presenta el caso de una mujer de 21 años con dolor abdominal, ictericia y una masa en el hipocondrío derecho, secundario a dicha patología, que fue sometida a una resección quirúrgica con anastomosis primaria. La evaluación anatomopatológica demostró una estructura quística de aspecto similar a una vesícula biliar, congestiva y pardusca, con inflamación crónica leve. Tuvo un postoperatorio satisfactorio y egresó con tratamiento antibiótico. El quiste coledociano debe considerarse en el diagnóstico diferencial de aquellos pacientes con dolor abdominal y masa en el cuadrante.Choledochal cyst is a dilatation of a component of the biliary tree and it may include both intra and extrahepatic sites. They are classified into five types, all of which are relatively rare. Previously, choledochal cysts were treated with biliaryenteric bypass procedures. The current recommendation is to attempt their complete excision to minimize the known risk of fecoming malignant and the development of recurrent cholangitis or pancreatitis that may occur in these patients. We present here the case of a 21 year old woman with abdominal pain and jaundice due to a type 1 choledochal cyst. The cyst was removed and patient did fine.

Testicular myeloid sarcoma: case report  

Directory of Open Access Journals (Sweden)

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

Testicular lesions of streptozotocin diabetic rats.  

Science.gov (United States)

Diabetes was induced in adult male albino rats by a single intravenous injection of streptozotocin (75 mg/kg body weight). The diabetes was allowed to stabilize for at least 15 days, whereafter the testicular and seminal vesicle histology was studied at various time intervals. Reduction in testis weights and tubule diameters was significant after 2 weeks of diabetes. The changes in seminiferous tubules ranged from premature sloughing of epithelium to total cessation of spermatogenesis. The testicular histology of diabetic animals frequently greatly simulated the situation described following hypophysectomy. By subjective visual assessment the number of Leydig cells was found to be normal or reduced in all of the diabetic animals. Diabetes was also demonstrated to induce seminal vesicle atrophy, which did not show any correlation with the degree of testicular lesions. The possible etiology of testicular damage in diabetic animals is discussed. PMID:130334

Cadmium-induced testicular injury  

International Nuclear Information System (INIS)

Cadmium (Cd) is an environmental toxicant and an endocrine disruptor in humans and rodents. Several organs (e.g., kidney, liver) are affected by Cd and recent studies have illustrated that the testis is exceedingly sensitive to Cd toxicity. More important, Cd and other toxicants, such as heavy metals (e.g., lead, mercury) and estrogenic-based compounds (e.g., bisphenols) may account for the recent declining fertility in men among developed countries by reducing sperm count and testis function. In this review, we critically discuss recent data in the field that have demonstrated the Cd-induced toxicity to the testis is probably the result of interactions of a complex network of causes. This is likely to involve the disruption of the blood-testis barrier (BTB) via specific signal transduction pathways and signaling molecules, such as p38 mitogen-activated protein kinase (MAPK). We also summarize current studies on factors that confer and/or regulate the testis sensitivity to Cd, such as Cd transporters and metallothioneins, the impact of Cd on the testis as an endocrine disruptor and oxidative stress inducer, and how it may disrupt the Zn2+ and/or Ca2+ mediated cellular events. While much work is needed before a unified mechanistic pathway of Cd-induced testicular toxicity emerges, recent studies have helped to identify some of the likely mechanisms and/or events that take place during Cd-induced testis injury. Furthermore, some of the recent studiury. Furthermore, some of the recent studies have shed lights on potential therapeutic or preventive approaches that can be developed in future studies by blocking or minimizing the destructive effects of Cd to testicular function in men.

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.

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

Directory of Open Access Journals (Sweden)

Full Text Available Objetivos: Determinar si los preparados de estrógenos y progestágenos orales, usados ampliamente en la práctica clínica, son realmente útiles en el manejo de quistes ováricos con características de benignidad en la ecogratia transvaginal. Método: Se realizó una búsqueda detallada en bases de datos electrónicas de uso frecuente. Dos de los artículos encontrados cumplían con los criterios de inclusión. Resultados: Mackenna y cois trabajaron con un total de 50 mujeres con quistes funcionales inducidos farmacológicamente. Dividieron en forma aleatoria a las pacientes en dos grupos. Uno de ellos recibió anticonceptivos orales y el otro no. No se encontraron diferencias significativas en el tiempo de desaparición de las lesiones a la ecografía entre ambos grupos. Bayar y cois, siguieron a 141 mujeres en edad fértil que presentaban quistes simples en la ecografía. Conformaron dos grupos. El primero se manejó con anticonceptivos orales y el segundo de manera expectante. En ese estudio no se encontraron diferencias significativas en la reducción del tamaño de los quistes en el tiempo al comparar ambos grupos. Conclusiones: Sería adecuado que el médico al enfrentarse a mujeres premenopáusicas con quistes simples, considerase inicialmente el manejo conservador por al menos dos meses y luego evaluase la persistencia o desaparición de éstos con estudio de imágenesObjective: To establish if oral contraceptives composed by estrogens and progestogens are useful in the management of ovarian cysts that appear benign in transvaginal ultrasound. Method: A detailed search was performed in electronic data bases. Two of the articles found met the inclusion criteria. Results: Mackenna and cols, worked with fifty women with functional ovarian cysts pharmacologically induced. They divided their patients randomly in two groups. One of them received oral contraceptives and the other did not. There were no significant differences between the groups in the time of disappearance of the lesions in ultrasound. Bayar and cols, studied 141 fertile women with simple ovarian cysts in ultrasound. One group received oral contraceptives and the other did not. In this study there were no significant differences between groups in the reduction of the size of the cysts over time. Conclusions: In premenopausic women with simple ovarian cysts it would be adequate to considerate expectant management initially for at least two months

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.

Cutaneous metastasis of epidermoid carcinoma of the larynx: a case report  

Directory of Open Access Journals (Sweden)

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

Dyke-Davidoff-Masson Syndrome Associated with Epidermoid Tumour and Arachnoid Cyst: A Case Report  

Science.gov (United States)

Background: Dyke-Davidoff-Masson Syndrome (DDMS) is a rarely seen clinical entity which is characterised by cerebral hemiatrophy, contralateral hemiparesis and epilepsy. Radiological features are typical, such as unilateral atrophy of the cerebral hemisphere and associated compensatory bone changes in the skull, like thickening, enlargement of the paranasal sinuses and mastoid air cells. Case Report: In this article, we report the first case of DDMS associated with epidermoid tumour and arachnoid cyst, who underwent operation for an epidermoid tumour in the inter-hemispheric region. To our knowledge, this is the first report of DDMS associated with multiple intracranial pathologies and this association has not been previously described in the literature. Conclusion: Any patient who receives DDMS in the light of clinical and radiological findings should be investigated for concomitant pathologies. Different sequences of MRI may be useful in the diagnosis of other intracranial lesions.

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

Energy Technology Data Exchange (ETDEWEB)

In order to study the role of magnetic resonance imaging (MRI) in diagnosing intracranial epidermoid, we evaluated the MRI findings on five cases with such tumor, all of which were surgically verified. In addition to standard spin-echo (SE) images obtained in all cases, diffusion-weighted images were acquired in two patients. In four patients, the tumor revealed to be almost isointense relative to cerebrospinal fluid (CSF) on both T[sub 1]-and T[sub 2]-weighted images, while it tended to show slightly hyperintense to CSF on proton-density-weighted images; thus, based on the signal intensity on standard SE images the distinction between epidermoid and arachnoid cyst may be difficult. Furthermore, the presence of the tumor which has a tendency to grow in and along the subarachnoid space causing relatively minimal mass effect may be overlooked. Diffusion-weighted images were shown to have advantages in such cases by demonstrating the tumor unequivocally as a mass of high signal, and differentiating it from arachnoid cysts. In the remaining patient, its appearance was atypical, showing bright signal on both T[sub 1]-and T[sub 2]-weighted images. In conclusion free of bone artifacts, multiplanar MRI with additional diffusion-weighted images provides a clear demonstration of epidermoid, and its differentiation from arachnoid cyst, thus obviating the need for CT cisternography.

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

International Nuclear Information System (INIS)

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

Unilateral testicular seminoma with simultaneous contralateral torsion: a case report  

Directory of Open Access Journals (Sweden)

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

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Objetivos: Presentamos un caso de masa testicular derecha en varón de 65 años con afectación sincrónica de piel y anillo de Waldeyer, datos que nos orientan a que se trate de un linfoma testicular maligno por lo característico de la presentación del cuadro clínico. 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.

Treinta y cinco pacientes fueron tratados mediante láser de CO2, en 10 se realizó cierre directo de la lesión y en los restantes 25 algún colgajo local, regional o a distancia. Se analizó la presencia de sintomatología dolorosa durante el postoperatorio, el grado de retracción cicatricial y la presencia de alteraciones funcionales en la deglución y habla en función de la resección y reconstrucción realizada. Resultados: Obtuvimos un menor grado de dolor y de retracción cicatricial postoperatoria mediante el empleo de láser de CO2, minimizando así las secuelas funcionales de habla (mejor articulación de la palabra) y deglución (recuperación funcional más eficaz y precoz). Conclusión: La resección mediante láser de CO2 se ha convertido en el tratamiento de elección de los pequeños tumores mucosos orales y orofaringeos, por la ausencia de necesidad reconstructiva, menor retracción cicatricial y buena evolución postoperatoria.

Objective: To analyze the postoperative evolution, in the patients treated by oral and oropharyngeal epidermoid carcinomas, after CO2 laser resection. To compare it with that of the patients treated by means of conventional surgical methods, achieving the reconstruction through direct suture or the employment of local, regional or distance flaps. Methods: A prospective study was designed including 70 patients treated by oral and oropharyngeal epidermoid carcinomas. Thirty-five patients were treated by means of CO2 laser, in 10 cases direct wound-closure was realized, and in the remaining 25 patients some local, regional or distance flap were used. There were analysed the presence of postoperative pain, the degree of cicatricial retraction, and the speech and swallowing functional results. Results: We obtained a smaller painful degree and postoperative cicatricial retraction by the employment of CO2 laser. It permits minimizing the functional speech sequels (better words articulation) and swallowing (effective and precocious functional recovery). Conclusion: CO2 laser resection has become the elective treatment for small oral and oropharyngeal epidermoid carcinomas. The reasons are the absence of reconstructive surgery necessity, the scarce cicatricial retraction, and the excellent postoperative evolution.

On radiotherapy of testicular tumours  

International Nuclear Information System (INIS)

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

Testicular cancers occurring in brothers with cryptorchism.  

Science.gov (United States)

We report a case of familial testicular cancer associated with undescended testes in two brothers. The older brother (49 years) presented with a testicular tumor located in the right inguinal canal. The pathologic diagnosis was pure seminoma. Computerized tomography revealed iliac and retroperitoneal lymph node metastases. Four years later, the younger brother (44 years) developed bilateral testicular tumors, one located in the inguinal canal, the other located in the pelvic cavity. The pathologic diagnosis of both tumors was pure seminoma. Radiological examination revealed retroperitoneal lymph node metastases. Both patients received cisplatin-based combination chemotherapy as the initial treatment. The older brother suffered from repeated recurrences with lymph node metastases in the iliac and inguinal regions, but he was successfully treated with high-dose chemotherapy. The younger brother achieved long-term remission after retroperitoneal lymph node dissection following initial chemotherapy. We briefly review the reported cases of familial testicular cancer and discuss the association of the maldescent of the testes and familial testicular cancer cases. PMID:11972655

Testicular self-examination amongst genitourinary medicine clinic attendees.  

Science.gov (United States)

Advancements in the diagnosis and treatment of testicular cancer now give a five-year survival rate of 97.2%. Delayed presentation remains the primary cause of poor outcome and recommendations have stressed that men, particularly those with risk factors, should undertake regular testicular self-examination. This study aimed to determine testicular self-examination knowledge and practices amongst 740 unselected men attending a genitourinary medicine clinic via questionnaire survey. Of respondents, 75.8% of men had heard of testicular cancer, and 79.9% had heard of testicular self-examination. Of these, 41% of men had been taught testicular self-examination; 73.9% of them by a doctor or nurse. Importantly, 79.2% had previously performed testicular self-examination. The most common reason for not performing testicular self-examination was 'Don't really know what to look for' (59.5%). Men previously taught testicular self-examination were 11.5 times more likely to perform the practice than those untaught. Of respondents, 74.1% wanted more information regarding testicular self-examination whilst attending the clinic. This study shows an increased level of testicular self-examination amongst genitourinary medicine attendees than has been previously demonstrated in other patient groups. There remains room for improvement via further health promotion and research on the effectiveness of testicular self-examination. PMID:24516080

Pulmonary sarcoidosis associated with Leydig cell testicular neoplasm.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The first case of association between Leydig cell testicular tumor and sarcoidosis is reported. From a review of the literature, this is the ninth case of association between a testicular tumor and Besnier's disease. Lung biopsy should always be performed in patients with testicular cancer when retroperitoneal lymph node involvement cannot be demonstrated in order to avoid unnecessary antineoplastic chemotherapy.

Single testicular metastasis mimicking primary testicular neoplasm: a rare manifestation of prostate cancer  

Directory of Open Access Journals (Sweden)

Full Text Available The incidence of secondary testicular tumors ranges from 0.02 to 2.5% among autopsies in general. With the exception of leukemias and lymphomas, prostate cancer is the most common primary site. It is diagnosed in autopsies or incidentally, following therapeutic orchiectomies in more advanced stages of the disease. In the present report, we show a case of testicular metastasis derived from prostate neoplasm whose clinical presentation as a single metastasis was similar to a primary testicular neoplasm. The diagnosis was evidenced after orchiectomy by histological examination and immunohistochemical tests.

Frequency of testicular atrophy following incarcerated hernia.  

Science.gov (United States)

From 1977 to 1981, 40 infants and children were operated for incarcerated inguinal hernia, 35 boys and 5 girls. During this time, 903 hernias were cured. Follow-up examination has been possible with 32 boys, from 6 months to 5 years after surgery. Three have an irreversible lesion of the testis (2 atrophies, 1 orchiectomy), 4 a decrease of testicular volume, 1 has a bilateral retentio testis, 1 has a cryptorchidism on the non-operated contralateral side and 23 are normal. Risk factors of testicular lesions were studied with regard to age, duration of symptoms, reducIbility of hernia and to other clinical findings, and the follow-ups are evaluated with regard to macroscopic operative appearance of testicles. The group of infants less than 1 month of age with symptoms for more than 24 hours and with ileus is the highest risk group for testicular infarction at the time of incarceration of hernia.

[Genetics of testicular germ cell tumors].  

Science.gov (United States)

Testicular cancer is by far the most common neoplasm among young males between the ages of 20 and 40 years and with an increasing incidence rate worldwide. Congenital malformations of the male genitals, such as cryptorchidism or inguinal hernia are established risk factors. Men with a family history of testicular cancer are also associated with an increased risk of the disease. In the testes more than 90?% of tumors develop from germ cells (progenitor cells) and represent a histologically heterogeneous group. Germ cell tumors in extragonadal localizations are rare. Isochromosome i(12p), the typical marker chromosome in testicular germ cell tumors, occurs as an early event in tumorigenesis. Spermatocytic seminoma is a rare variant of germ cell tumors and according to the current classification is a distinct entity with different morphological, clinical and also cytogenetical features compared with other germ cell tumors.

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

[Epidermoid cyst of the cerebellopontine angle. A surgical series of 10 cases and review of the literature].  

Science.gov (United States)

Epidermoid cyst or cholesteastoma is a congenital slow growing lesion. It usually arises in the paramedian cisterns of the posterior fossa. Its incidence varies between 0.2 and 1% of all intracranial tumors. The cerebello-pontine angle (CPA) is the most common localization. Our study reports 10 observations of CPA epidermoid cysts, treated in our department between 1989 and 1999. The age of our patients ranged from 20 to 45 years, with male predominance. The patients were admitted with symptoms of cerebello-pontine angle syndrome or signs of posterior fossa tumor. CT-scan was performed in all cases and MRI was performed in 5 patients. The audiometric explorations only provided an orienting contribution. Treatment was exclusively surgical. The retro-sigmoid approach was used in 6 cases, the sub-occipital in 30% and a subtemporal approach in one case. Total resection of the epidermoid cysts was accomplished in 4 cases, and subtotal resection in 4 cases. Two patients underwent partial resection and underwent a revision procedure. The histological examination showed an epidermoid cyst in all cases. The clinical course was controlled in 6 patients: 4 patients recovered and became symptom free. A persisting neurologic deficit was observed in two cases (hearing loss, dysphonia); 4 patients were lost to follow-up. Epidermoid cyst is a benign tumor. Total resection is the ideal treatment, but we have to be aware, taking into consideration the adherence of the tumor to neurovascular structures, of the risks at attempting total resection.

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.

Intracardiac metastasis from germ cell testicular tumor.  

Science.gov (United States)

Intracardiac metastases of germ cell testicular tumors are not commonly seen in clinical practice. The clinical presentation of right-sided heart metastases ranges widely. Depending upon its size and intracardiac location, it could be highly symptomatic, leading to a congestive heart failure, pulmonary embolism, and death, or completely asymptomatic. Improved imaging techniques and treatment strategies demonstrate that right-sided heart metastasis should be considered a potentially dangerous but treatable disease. Presented is the case of a 24-year-old man with a testicular nonseminomatous germ cell tumor, which after metastasizing in the right atrium differentiated into a teratoma and resulted in an inflow obstruction of the right ventricle.

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.

Variant origin of right testicular artery – a rare case  

Directory of Open Access Journals (Sweden)

Full Text Available Testicular arterial anatomy is important for testicular and renal surgeries. It may vary at the origin and arise from renal artery, suprarenal artery or lumbar artery. During routine dissection of 52-year-old male cadaver; the right testicular artery arising from right aberrant renal artery was found. Anatomical variation of testicular arteries is reported to be 4.7%. Presence of aberrant renal artery is seen in 13–16% of cases only. The origin of right testicular artery from right aberrant renal artery is very rare. Thus knowledge of this type of variation is very important in avoiding complications during operative surgeries.

Energy Technology Data Exchange (ETDEWEB)

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

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

Directory of Open Access Journals (Sweden)

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

Age-related differences in testicular microcirculation.  

Science.gov (United States)

Different aspects of testicular microcirculation were studied in rats aged 20, 24 or 90 days, in order to determine if maturational changes in the testis could influence its vasculature. Using laser Doppler flowmetry, it was found that vasomotion was not present in 20-day-old rats, but it could be induced by hCG-treatment given 32 h prior to flow measurements. In rats aged 24 days vasomotion was present in the testis but it was not influenced by hCG treatment, in contrast to adult rats in which testicular vasomotion disappeared after hCG treatment. In all age-groups, hCG treatment induced an increase in testicular interstitial fluid (IF) volume, which was most pronounced in young rats. In young rats, as in adults, there was an increase in the volume density of polymorphonuclear (PMN) leucocytes in testicular blood vessels after hCG treatment. However, rats aged 20 or 24 days did not exhibit any significant extravascular migration of leucocytes as occurred in adult rat testis after hCG injection. The deposition of colloidal carbon particles observed in adult rats after hCG-treatment was also not seen in young rats. It is concluded that the vasculature of the immature rat testis responds to hCG stimulation with an increase in IF volume. However, when compared to adult rats, different mechanisms may be operating because no evidence for opening of inter-endothelial cell gaps was observed in the testis of young rats. PMID:2387639

GPER signaling in spermatogenesis and testicular tumors  

Directory of Open Access Journals (Sweden)

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

Microdissection testicular sperm extraction: an update  

Science.gov (United States)

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

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.

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

International Nuclear Information System (INIS)

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)

Fibroma ameloblástico versus quiste folicular hiperplásico / Ameloblastic fibroma versus hyperplastic follicular cyst  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Resumen: El fibroma ameloblástico (FA) es un tumor odontogénico mixto, compuesto por tejido mesenquimal y epitelio odontogénico, representando el 2% de los tumores odontogénicos, mientras que el quiste dentígero o folicular (QF), el segundo quiste odontogénico en frecuencia, está compuesto exclusiva [...] mente por tejido conjuntivo laxo (mesénquima), si bien, el saco fibroso puede contener restos de epitelio odontogénico incluidos, dando lugar a una imagen histológica muy similar. La importancia de esta diferenciación radica en el tratamiento, que es ligeramente más agresivo en el FA y en el comportamiento biológico, ya que el FA puede derivar en un sarcoma ameloblástico, y el QF puede evolucionar hacia ameloblastoma y más raramente carcinoma mucoepidermoide. Abstract in english Abstract: Ameloblastic fibroma (AF) is a mixed odontogenic tumor composed of mesenchymal tissue and odontogenic epithelium, accounting for 2% of all odontogenic tumors, while dentigerous or follicular cyst (FQ), second odontogenic cyst in frequency, is formed exclusivelly by soft conective tissue (m [...] esenchyme). Nevertheless, hiperplastic fibrous sac may contain rests of odontogenic epithelium, showing a similar histologic pattern. The importance of an adequate differentiation lies in the treatment, which is slightly aggresive for AF, and regarding the biological behaviour of both lesions, since AF might become in an ameloblastic sarcoma, while over an FQ could develope an ameloblastoma or even a mucoepidermoid carcinoma.

Prognostic factors in megavoltage radiation therapy of central epidermoid lung carcinoma  

International Nuclear Information System (INIS)

Radical program radiotherapy was provided to 403 patients with inoperable central epidermoid lung carcinoma that does not extend beyond one half of the thoracic cavity. Long-term therapeutic results depend on numerous factors the interrelationships of which cannot be revealed without present-day methods of data analysis. The use of computers (a method of parameter grouping and semi-automatic classification - ''teaching without a teacher'') made it possible before treatment to approach the level of group prognosis by symptoms; taking into account the time course of symptoms in the process of radiation therapy and after its termination - to reach the level of individual prognosis for 22% of the patients

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)

Differentiation of testicular diseases via dynamic MRT  

International Nuclear Information System (INIS)

The present study aimed at resolving whether dynamic MRT can improve diagnostic relevance in diseases of the testes compared with conventional spin echo images. The testes of 20 healthy volunteers and of 16 patients of the Department of Urology of the University of Bonn were examined by means of MR tomography. Within 12 hours after MR tomography the patients were surgically explored, biopsied and if necessary orchiectomised. Results obtained with the volunteers were uniform and well reproducible, independent of external influences. On comparing the maximal enhancement curves of the examined various testicular tumors with the standard values established by examining the healthy volunteers, the curves obtained with the malignant testicular tumors were always clearly above the chosen confidence range of 3 standard deviations so that malignancy diagnosis was easy. However, the degree of maximal enhancement did not enable us to arrive at a conclusion in respect of the tumor type or the degree of malignancy. The greatest enhancement occurred with the tumor of Sertoli's cell which could thus be clearly differentiated against the other malignant testicular tumors. Due to masking of the gadolinium effect by haemosiderin deposits, haemorrhagica in the tumor tissue should be excluded by means of T2-weighted spin echo sequences before following up a suspicion of malignant testicular tomor. Benign intratesticular changes could be safely separated from malignant findings by means of the maximal enhancement curve lying in the normal range or below the curve of the volunteers. As with other organs, dynamic MR tomography yields definitely more and better information than conventional MR tomography also in the diagnosis of testicular tumours. However, these ''pros'' do not offset the ''cons'' of high costs of such examinations. (orig.)

Pese a las controversias que detallamos, nuestra opción terapéutica fue la extirpación de la masa residual tras la quimioterapia asociada a orquiectomía bilateral en el mismo acto. Concluimos que ante un tumor retroperitoneal, la existencia de alteraciones ecográficas en los testículos, pese a una palpación normal, debe hacer pensar en un "Síndrome de burn out", siendo obligatoria la biopsia testicular bilateral. La exploración quirúrgica de los mismos e incluso la orquiectomía son opciones a valorar en función de cada paciente. Abstract in english Differentiating a primary retroperitoneal seminoma from a metastatic testicular tumor with an occult testicular primary or a burned out testicular cancer remains difficult. We present a case of a burned out tumor. The patient had a retroperitoneal seminoma with ultrasonically and pathologically demo [...] nstrated abnormalities in both testes, but without evidence of tumor. The patient received chemotherapy and underwent surgery of the residual retroperitoneal mass and bilateral orchiectomy. All surgical specimens were negative for testis cancer. Conclusion: Primary extragonadal germ cell tumors in the retroperitoneum are a rare entity. The presence of a retroperitoneal tumor with ultrasonographical abnormalities in testicular evaluation should be considered as a metastases of a burned out testicular cancer, and biopsy is mandatory. Surgical evaluation and orchiectomy should be evaluated in a individual setting.

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

International Nuclear Information System (INIS)

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

[A case of cavernous sinus epidermoid: anatomical classification and surgical approach].  

Science.gov (United States)

Epidermoid rarely appears in the cavernous sinus. We encountered a 41-year-old man with left abducens nerve palsy. A round-shaped, low-density lesion on CT was located lateral to the left cavernous sinus with a compressed and thinned lateral wall of the sphenoid sinus. We could not identify cranial nerves in the cavernous sinus, which was found to be packed with a non-enhanced, high-intensity tumor on both T1 and T2 MRI. Part of the tumor capsule and its pearly contents were removed with an intradural subtemporal approach, and an inner membranous layer with cranial nerves and a tumor capsule were seen at the bottom of the tumor cavity. Postoperatively, complete cure was achieved. Reviewing similar cases, we found 18 cavernous sinus epidermoids:extracavernous type in 5;interdural in 10;and intracavernous in 3. The interdural type could be further divided into two subtypes:superficial cavernous sinus and inner membranous types. The present case belongs to the former. Frontotemporal and subtemporal procedures via both intra- and extradural approaches are relatively safe for lesions except for the intracavernous type, because cranial nerves are not located in the lateral wall of the tumor. MRI provides more useful information on cranial nerves and aid in choosing a better treatment strategy. PMID:24501189

SEVERE TESTICULAR ATROPHY DOES NOT AFFECT THE SUCCESS OF MICRODISSECTION TESTICULAR SPERM EXTRACTION  

Science.gov (United States)

Introduction and Objectives Men with azoospermia and severe testicular atrophy may be counseled to avoid sperm retrieval due to perceived limited success. We evaluated the outcomes of microdissection testicular sperm extraction (micro-TESE) in men with severe testicular atrophy (volume ? 2 mL). Methods We reviewed the records of 1127 men with nonobstructive azoospermia who underwent micro-TESE followed by intracytoplasmic sperm injection. The men were classified into three groups based on average testicular volume (mL), ?2, >2–10, >10. Sperm retrieval, clinical pregnancy, and live birth rates were calculated. The clinical features evaluated included age, FSH level, history of cryptorchidism, Klinefelter syndrome, varicocele, and testicular histology from diagnostic biopsy. Result(s) Testicular sperm were successfully retrieved in 56% of the men. Sperm retrieval rates (SRR) in men with testicular volumes of ? 2, >2–10, and >10 mL was 55%, 56% and 55% respectively. Of those men who had sperm retrieved, clinical pregnancy and live birth rates were similar in the three groups (55.2%, 50.0%, and 47.0%; and 47.2%, 43.0% and 42.2% respectively). Of the 106 men with average testis volume ? 2 mL bilaterally, men who had sperm retrieved were younger (31.1 vs. 35.2 years), and were more likely to have a history of Klinefelter syndrome (82.2% vs 55.6%) compared to those in whom sperm was not found (p 2 mL (72.6% vs 5.3%, p<0.0001). Men younger than 30 years with Klinefelter syndrome had a higher SRR (81.8%) compared to men older than 30 without Klinefelter syndrome (33%, p<0.01). There was no cut-point for age beyond which sperm could not be retrieved in men with small testes. On multivariable analysis, younger age was the only preoperative factor associated with successful sperm retrieval in men with small testes (<2mL). Conclusion(s) Testicular volume does not affect sperm retrieval rates at our center with micro-TESE. For men with the smallest volume testes, those younger men with Klinefelter syndrome had the highest sperm retrieval rates. Severe testicular atrophy should not be a contraindication for micro-TESE.

Quiste endodérmico supratentorial: caso clínico y revisión de la literatura / Supratentorial endodermal cyst: Case report  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Los quistes endodérmicos que afectan al sistema nervioso central son lesiones expansivas muy poco frecuentes que se sitúan con mayor frecuencia a nivel espinal. Existen poco casos de localización intracraneal descritos en la literatura, la mayoría de ellos en la fosa posterior. Su etiopatogenia perm [...] anece aún desconocida. Presentamos el caso de un varón de 62 años que debuta con un cuadro de desorientación y comportamiento desinhibido tras sufrir un traumatismo craneoencefálico como consecuencia de un accidente de tráfico. En la TC craneal realizada de urgencia se objetiva una lesión quística frontal izquierda de gran tamaño con importante desplazamiento de línea media. Se punciona y evacua el contenido del quiste obteniéndose un líquido opalino rico en proteínas y elementos celulares no identificados. La RMN nos confirma los hallazgos radiológicos previos. El paciente es intervenido de forma reglada mediante craneotomía, evacuación completa del contenido y extirpación de las paredes de la lesión. El estudio anatomopatológico resulta ser compatible con el diagnóstico de quiste endodérmico. Se han descrito casos de evolución agresiva con diseminación y recidiva tras manipulación quirúrgica de la lesión; por lo tanto, el tratamiento debe consistir en la extirpación completa de la misma. Para ello será necesario realizar el diagnóstico diferencial con otras lesiones quísticas intracraneales con el fin de adecuar el tratamiento a cada caso. Abstract in english Endodermal cysts (EC) of the central nervous system are very uncommon lesions predominantly located in the spinal canal. Although rare, intracranial EC have been mainly described in the posterior fossa, with the supratentorial location considered exceptional. Apart from the low frequency of these le [...] sions, their pathoembriology still remais unknown. We report a patient with a huge frontal EC and review the literature. A 62-year-old man presented with abnormal behaviour, disorientation and decreased level of consciousness after moderate head injury. Initial cranial CT scan revealed a large cyst in the left frontal region with marked midline shift. Emergency puncture and decompression of the cyst demonstrated a milky fluid with high protein levels. Cranial MRI after patient improvement confirmed the existence of the cystic lesion with less mass effect. Delayed surgery was performed with craniotomy and total removal of the cyst. Pathological examination confirmed the presence of a typical EC. Patient made a complete recovery on follow-up with no recurrence on postoperative MRIs. Differential diagnosis of EC based on radiological data is quite difficult. As aggresive behaviour of this condition has been described following incomplete resections, the treatment of choice is a radical removal of the cyst in one or two stages depending on patient clinical condition.

Filarial granuloma of the testicular tunic mimicking a testicular neoplasm: a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction Any firm or solid intratesticular mass on examination and/or any hypoechoic area within the tunica albuginea on imaging is markedly suspicious for testicular cancer. Filarial involvement of the testicular tunic has not been reported previously. Case presentation A 32-year-old man presented with a history of noticing a swelling in his right testicle for a period of 1 month which had become painful over the 10 days before presentation. Pre-operative imaging failed to shed light on the nature of the lesions (malignant or benign. The diagnostic dilemma was explained to the patient and informed consent was obtained for an orchiectomy. The patient underwent a high inguinal orchiectomy. The histopathology revealed a filarial granuloma of the testicular tunic. Conclusion While it is generally regarded that any testicular swelling, especially in a young person, should be treated as a malignancy unless proven otherwise, it is important to remember that infectious diseases such as filariasis and tuberculosis may mimic neoplasms. Careful consideration of these diagnoses must be given when dealing with testicular swellings especially in areas where the prevalence of these diseases is high.

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.

Isolated relapse ganglions of epidermoid carcinomas of superior aero-digestive ways:Does the brachytherapy have its place  

International Nuclear Information System (INIS)

The brachytherapy of isolated ganglions relapses of epidermoid carcinomas allows the ganglions control to three years in 25% of cases. Taking into account its toxicity (6% of deceases) and the unfavorable prognosis of the illness, a cervical ganglion surgery must be always preferred. (N.C.)

Late solitary testicular metastasis from rectal cancer  

Directory of Open Access Journals (Sweden)

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

Testicular dysgenesis syndrome and Leydig cell function  

DEFF Research Database (Denmark)

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

Testicular cancer and HPV semen infection  

Directory of Open Access Journals (Sweden)

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

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.)

Malignant tumours of the thestis are mainly found in the third and fourth decade of life, a period in wich most men are highly sexually active. Although post-treatment sexual funtioning is a very relevant aspect of the quality of life, only a very small amount of information is available about the sexual sequelae of the current therapies for testicular cancer. In this thesis, the impact of the different treatment modalities on organ systems important for normal sexual functioning was studied....

Echogenic mass as a sign of testicular torsion  

International Nuclear Information System (INIS)

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

A Rare Cause of Testicular Metastasis: Upper Tract Urothelial Carcinoma  

Science.gov (United States)

Metastatic testicular cancers are rare. Primary tumor sources are prostate, lung, and gastrointestinal tract for metastatic testicular cancers. Metastasis of urothelial carcinoma (UC) to the testis is extremely rare. Two-thirds of upper tract urothelial carcinoma (UTUC) is of invasive stage at diagnosis and metastatic sites are the pelvic lymph nodes, liver, lung, and bone. We report a rare case of metastatic UTUC to the testis which has not been reported before, except one case in the literature. Testicular metastasis of UC should be considered in patients with hematuria and testicular swelling. PMID:25120937

[Testicular bilharzioma by Schistosomia haematobium: about two cases].  

Science.gov (United States)

Bilharzioma are inflammatory pseudotumors, which often pose the problem of differential diagnosis with neoplastic processes. Using the keywords "testicular" and "schistosomiasis", there are only 14 cases of testicular bilharzioma identified on PubMed. The authors report two new cases in a 6-year-old child and an adult of 38 years, collected over a period of 5 years. In both cases, orchidectomy was performed and histological analysis of the surgical specimen was allowed to diagnose testicular bilharzioma by Schistosomia haematobium. The authors emphasize the need to evoke a bilharzioma before any testicular nodule in a patient living in an endemic area. PMID:24365632

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.

Nursing supports neonatal porcine testicular development.  

Science.gov (United States)

The lactocrine hypothesis suggests a mechanism whereby milk-borne bioactive factors delivered to nursing offspring affect development of neonatal tissues. The objective of this study was to assess whether nursing affects testicular development in neonatal boars as reflected by: (1) Sertoli cell number and proliferation measured by GATA-4 expression and proliferating cell nuclear antigen immunostaining patterns; (2) Leydig cell development and steroidogenic activity as reflected by insulin-like factor 3 (INSL3), and P450 side chain cleavage (scc) enzyme expression; and (3) expression of estrogen receptor-alpha (ESR1), vascular endothelial growth factor (VEGF) A, and relaxin family peptide receptor (RXFP) 1. At birth, boars were randomly assigned (n = 6-7/group) to nurse ad libitum or to be pan fed porcine milk replacer for 48 h. Testes were collected from boars at birth, before nursing and from nursed and replacer-fed boars at 50 h on postnatal day (PND) 2. Sertoli cell proliferating cell nuclear antigen labeling index increased (P ESR1, or VEGFA levels. However, testicular relaxin family peptide receptor 1 (RXFP1) levels increased (P < 0.01) with age and were greater in replacer-fed boars on PND 2. Results suggest that nursing supports neonatal porcine testicular development and provide additional evidence for the importance of lactocrine signaling in pigs. PMID:24906933

Doppler sonographic findings in testicular microlithiasis  

Scientific Electronic Library Online (English)

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

Result: The security of the clinical diagnosis it was respectively of 94,1%, 92,2% and 98% for the thyroglossal, branchial and dermoid cysts. We find bigger tendency to the clinical error in branchial cysts, where the most frequent confusions are presented with inflammatory linfoadenopathy. The security of the Fine Needle Aspiration Biopsy was of 96,1% and 94,1% for the thyroglossal and branchial cysts respectively. Conclusions: Clinical diagnosis is not enough in occasions, for what is necessary to appeal to means complementary diagnoses, as the Fine Needle Aspiration Biopsy; however this test is not 100% sure.

Resultado: Histológicamente se informa de tumor desmoide mesentérico. Se hace diagnóstico diferencial con un tumor de estroma gastrointestinal mediante el estudio inmunohistoquímico. Conclusiones: El tumor desmoide es un tumor raro. Se han descrito pocos casos en pacientes afectos previamente de tumor testicular. Debe incluirse en el diagnóstico diferencial de las recidivas por tumor testicular. Abstract in english Objective: Report of one case of desmoid tumor in a patient who had been treated of a testicular seminoma 26 months before, with excision of a retroperitoneal mass and chemotherapy. On follow-up he presented with a mesenteric abdominal mass which was clinically labeleled as a recurrence of the semin [...] oma. Results: Histologically it was reported as a mesenteric desmoid tumor. Differential diagnosis with gastrointestinal stromal tumor was performed with immunohistochemical studies. Conclusions: Desmoid tumor is rare. There are few cases reported in patients with history of previous testicular tumor. It should be included in the differential diagnosis of testicular tumor recurrences.

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, 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

Pheophorbide a mediated photodynamic therapy against human epidermoid carcinoma cells (A431)  

Science.gov (United States)

The objective of this study was to characterize the death mechanism of human epidermoid carcinoma cells (A431) triggered by photodynamic therapy (PDT) with pheophorbide a. First of all, significant inhibition on the survival of A431 cells (ATP level was also observed at 6 hrs after PDT. Typical apoptotic cellular morphology and a collapse of mitochondrial membrane potential occurred after PDT. The loss of mitochondrial membrane potential led to the release of cytochrome c from the mitochondria to the cytosol, followed by activation of caspase-9 and caspase-3. The activation of caspase-3 resulted in poly(ADP-ribose) polymerase (PARP) cleavage in A431 cells, followed by DNA fragmentation. In conclusion, the results demonstrated that pheophorbide a possessed photodynamic action against A431 cells, mainly through apoptosis mediated by mitochondrial intrinsic pathway triggered by ROS.

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

International Nuclear Information System (INIS)

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

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.

A wild 5-yr-old red deer (Cervus elaphus) was eulled from a privately owned herd because of deformed antlers, retained velvet and bilateral symmetrical testicular hypogonadism. The clinical and pathological changes seen in this deer were most consistent with congenital hypoplasia, but testicular atrophy was an alternative possibility for the etiology of their condition.

Distensión abdominal y edemas por quiste del cordón espermático Abdomina distention and edema due to spermatic cord cyst  

Directory of Open Access Journals (Sweden)

Full Text Available La distensión abdominal es un síntoma común, siendo en general la presentación inicial de enfermedades sistémicas o desórdenes gastrointestinales. Otras causas son infrecuentes. Los quistes del cordón espermático son poco frecuentes, pero aún más su ubicación intraabdominal, su tamaño habitual es insuficiente para producir distensión. El paciente presentado en este caso es un varón con criptorquidia bilateral admitido por distensión abdominal, interpretada inicialmente como síndrome ascítico edematoso. La ecografía interpretó la distensión como ascitis tabicada, y la tomografía computada como debida a un gran quiste. En la exploración quirúrgica se diagnosticó un quiste gigante del cordón espermático de ubicación abdominal.Abdominal distention is a frequent symptom, being often the initial presentation of systemic diseases or gastrointestinal disorders. Other causes are uncommon. Spermatic cord cysts are infrequent, abdominal location is even rarer, and the size of the cysts is usually not enough to produce abdominal distention. In our case a man with bilateral cryptorchidism was admitted with abdominal distention and edema of the lower extremities initially interpreted as ascitic-edematous syndrome. Ultrasonography interpreted abdominal distention as septate ascites, computed tomography as a giant cyst. Exploratory surgery showed a giant spermatic cord cyst in the left spermatic cord.

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

College men's knowledge, attitudes, and beliefs about testicular cancer.  

Science.gov (United States)

There is a paucity of information about what college-age men know about testicular cancer, making targeted educational programs difficult. The most common age group affected by testicular cancer is 15- to 40-year-olds. Therefore, educating young men, including the college population, becomes paramount. Six focus groups were conducted with men between the ages of 18 and 23 years (N = 31) at a large public university in the Northeast. Major topics included risk factors for testicular cancer, screening and diagnosis, treatments, psychological effects, and beliefs about prevention and cure. Focus groups revealed college students have poor knowledge and even less understanding of testicular cancer. Students were interested in learning about testicular cancer and other health topics affecting college men, such as healthy diet and exercise and common infectious diseases on college campuses. Simple means to educate college men included courses or assignments that focused on health issues, brief factual information, health fairs, peer educators, and celebrity guest speakers.

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).

Metastasizing testicular seminoma in a pet rabbit.  

Science.gov (United States)

In the present study, a case of a spontaneously metastasizing seminoma in 9-year-old pet lionhead rabbit is described. The rabbit was presented with unilateral testicular enlargement and a palpable abdominal mass. Spiral computed tomography revealed the presence of an abdominal-pelvic mass in the region of the sublumbar lymph nodes. Testes and lymph nodes were collected, fixed in formalin, and submitted for histopathological examination. Microscopically, the normal architecture of the enlarged testis and lymph node was completely replaced by a diffuse malignant seminoma. PMID:22529136

Is self-measuring of testicular volume by a Prader orchidometer a valid method?  

DEFF Research Database (Denmark)

In this study, we compared sperm donors' and donor candidates' self-measured testicular volumes with testicular volumes obtained by an experienced examiner and investigated the association between the testicular volumes obtained by both methods and semen characteristics. We found that the participants obtained valid measurements of their own testicular volumes.

Interest of the serous dosage of HER-2/neu, EGFr, VEGF, IL6 and Ac anti-P53 among patients damaged by an esophagus epidermoid carcinoma, type epidermoid carcinoma whom treatment was an exclusive chemoradiotherapy  

International Nuclear Information System (INIS)

The serous concentrations of EGFr and HER2/neu seem to have a potential interest in the framework of the assumption of esophagus epidermoid carcinomas. A next step consists in comparing the serous value of these markers with their tissue expression on biopsies. A prospective study in parallel of a therapeutic trial is starting up to validate these results on a bigger number of patients. (N.C.)

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

Directory of Open Access Journals (Sweden)

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 2006 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.Background: Laparoscopic surgery is emerging as a useful alternative for the treatment of liver hydatid cysts.

A Case of Giant Epidermoid Cyst in the Floor of the Mouth That Caused Severe Obstructive Sleep Apnea Syndrome  

Directory of Open Access Journals (Sweden)

Full Text Available We describe here, a case with a giant epidermoid cyst in the floor of the mouth that caused severe obstructive sleep apnea syndrome (OSAS. A 37-year-old man was referred to our clinic because of a swelling in the floor of his mouth and sleep apnea syndrome. The occurrence of breathing disorders and daytime drowsiness was monitored to evaluate his OSAS 1 day before and 7 days after surgery. Before surgery, the apnea-hyponea index (AHI and Epworth Sleepiness Scale (ESS were 45.7 and 22, respectively. The clinical diagnosis was a dermoid or an epidermoid cyst that caused severe OSAS. Under general anesthesia, the patient underwent intraoral surgical removal of the cyst, along with aspiration to reduce the mass. After surgery, his sleep apnea syndrome was significantly improved. The postoperative AHI and ESS were 5.5 and 7, respectively. As of 2 years after the operation, there was no evidence of recurrence.

RESULTS: Testicular microlithiasis was identified in 20 testes of eleven children (0.71% of 1504 patients evaluated, through an ultrasound scan. Testicular microlithiasis was found in 5 children with cryptorchidism (3.93% of 127 patients, 4 children with retractile testes (14.8% of 27 patients, 1 child with a hypotrophic testis (100% of 1 patient, and 1 child with inguinal hernia (0.07% of 1349 patients. The children with testicular microlithiasis were submitted to annual physical examinations and ultrasound evaluations. CONCLUSIONS: Testicular microlithiasis was a rare condition and occurred in 0.7% of the subjects studied. The association with cryptorchidism, retractile and hypotrophic testis was significant.OBJETIVO: Avaliar a prevalência de microlitíase testicular entre pacientes pediátricos com afecções inguinoescrotais.

Full Text Available SciELO Venezuela | Language: Spanish Abstract in spanish Objetivo: Presentar el caso de una escolar con quiste tirogloso y granuloma de colesterol, hallazgo inusual que simuló clínica e imagenológicamente un carcinoma de tiroides. Esta asociación es infrecuente y hay pocos casos reportados. Caso clínico: Escolar femenina de 11 años, quién consultó por pre [...] sentar disfagia y tumoración en región anterolateral izquierda del cuello, de 3x3 cm, de consistencia dura, dolorosa a la palpación, sin signos de flogosis. Ultrasonido de cuello evidenció conducto tirogloso permeable en la línea media con presencia de nódulo hipoecoico, de bordes bien definidos, sin calcificaciones que medía 1,8 x 0,9 cm. Se extirpó la tumoración que medía 3x2, 5x0, 8cm. y se observó cavidad quística de 0,8 cm. de diámetro mayor que contenía material de aspecto gelatinoso. Por debajo de éste, se observó nódulo bien circunscrito de 1,5 cm. de diámetro mayor, constituido por tejido firme de color blanco-amarillento. El estudio histopatológico reveló un quiste revestido por epitelio cilíndrico y respuesta inflamatoria linfohistiocitaria, con células gigantes tipo “cuerpo extraño” alrededor de hendiduras; que correspondían a d dd epósito de colesterol. Conclusión: Se presenta este caso por su rareza y porque puede confundirse clínica e imagenológicamente con una neoplasia maligna. Asimismo, pudiera corresponder al primer caso reportado en nuestro país. Abstract in english Objective: We report the case of a 11 year- old girl with thyroglossal cyst and cholesterol granuloma, an unusual finding that clinically simulates thyroid carcinoma. This association is unusual and there are few reported cases worldwide. Case report: An 11-year-old girl consulted for dysphagia and [...] a 3 x 3 cm hard mass. The mass was painful on palpation and was located in the anterolateral neck left. It was phlogosis-free. A neck ultrasound showed a 1.8 x 0.9 cm permeable midline thyroglossal conduct with a hypoechoic nodule with well-defined edges but without calcifications. A 3 x 2,5 x 0, 8cm tumor was removed. A 0.8 cm cystic cavity that contained gelatinous material was observed. Below that cavity, a well-circumscribed nodule was observed. It measured 1.5 cm and was made up of firm yellowish tissue. The histopathology examination revealed a cyst lined with columnar epithelium and inflammatory linfohistiocitic response with foreign body type giant cells around cracks that corresponded to a cholesterol deposit. Conclusion: We present this case because it is very unusual and because it can be clinically and radiologically mistaken for a malignant tumor. It could be the first case ever reported in Venezuela.

Los carcinomas epidermoides de cabeza y cuello (CECC) ocupan el octavo lugar entre las neoplasias del sexo masculino, presentando el Principado de Asturias una de las tasas de incidencia más altas de España. Aunque se han realizado importantes avances en su diagnóstico y tratamiento, la supervivencia se ha modificado poco en los últimos años debido a que se diagnostican en estadios avanzados. El desarrollo de metástasis en los ganglios linfáticos cervicales es el factor que más influy...

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.
