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.

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

Scientific Electronic Library Online (English)

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

The differential diagnosis include intratesticular simple cyst, epidermoid cyst, tunica albuginea cyst, testicular teratoma, juvenil granulosa cell tumor-gonadal stromal tumor, cystic dysplasia of the rete testis, cystic lymphangioma, and testicular torsion Ussually enucleation is the best treatment. A thorough understanding of potentially cystic testis lesions in children leads to the best management choices and often to preservation of a substantial portion of the affected testis.

Teratoma quístico maduro testicular (quiste dermoide): Aportación de un caso y revisión de la literatura / Mature cystic teratoma of the testis (dermoid cyst): Case report and literature review  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Objetivos: Aportamos un caso de un teratoma quístico maduro testicular (quiste dermoide) en su variante pseudopilomatrixoma. 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.

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

Epidermoid Cyst of the Testicle: Unusual Magnetic Resonance Imaging Findings  

Energy Technology Data Exchange (ETDEWEB)

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

Intratesticular Epidermoid Cyst: A Rare Tumor  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Testicular epidermoid cyst is extremely rare injury, which in recent studies has been regarded as a tumor. Some authors consider this lesion as a cystic monodermal teratoma, the histogenesis remains controversial. In this study we provide clinical and morphological characteristics of an epidermoid cyst in the left testicle in a 16 years old patient, where apparently a nodular lesion in the left testicle was detected.

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

Intracranial high-density epidermoid  

International Nuclear Information System (INIS)

The authors report a case of frontal epidermoid cyst mimicking a meningioma with calcification. The patient was a 42-year-old male who was admitted to our hospital because of bilateral papilledema. A plain CT scan showed a huge homogeneous high-density area in the left frontal area, without any surrounding brain edema. Craniotomy revealed a huge cyst containing a blood clot and a small, hemorrhagic, fibrous nodule. Histological study showed that this cyst was an epidermoid cyst with a fibrous capsule containing heavy hemosiderin pigmentation and many small vessels. To our knowledge, there are only 5 reported cases of a dense epidermoid cyst. The etiology of the high density has usually been thought to be a high protein or calcium content, but in our case hemosiderin or hemoglobin is thought to be the main contributor to the high density.

Quistes esplénicos no parasitarios Nonparasitic splenic cysts  

Directory of Open Access Journals (Sweden)

Full Text Available Los quistes esplénicos no parasitarios son poco frecuentes. Sin embargo, es posible clasificarlos en primarios y secundarios dependiendo de la presencia o ausencia de revestimiento epitelial. Los síntomas tienen relación con el tamaño del quiste. Aunque no hay información basada en la evidencia que defina el manejo quirúrgico óptimo, se recomiendan las técnicas de cirugía conservadora (preservación del bazo en quistes no parasitarios. En la actualidad, la cirugía por laparoscopia es una alternativa. Se informan dos casos de quiste esplénico no parasitario. Ninguna de las pacientes registra antecedente de trauma. Se practica esplenectomía total por un quiste central y esplenectomía parcial por un quiste en el polo superior. Una de las pacientes presentó trombosis de la vena porta y esplénica posoperatoria.Nonparasitic splenic cysts are not common. They can be classified as either primary or secondary depending on the presence or absence of epithelial lining. Physical examination reveals that the symptoms are related to the diameter of the cyst. Although there is no evidence-based information regarding their optimal surgical treatment, more conservative surgical techniques (spleen-preserving should be attempted. Nowadays, laparoscopic surgery is a good option. We report two patients with no history of preceding trauma. In the first case, splenectomy was performed due to a cyst occupying the middle portion of the spleen; in the second case, the patient had a partial splenectomy to remove a cyst located in the upper pole. One of the patients developed a postoperative portal and splenic vein thrombosis.

Típicamente se presentan por un cuadro de dolor abdominal o masa palpable, pero en la actualidad se detectan cada vez con más frecuencia en estudios radiológic [...] os como incidentalomas. Los quistes suprarrenales cuentan con amplios diagnósticos diferenciales, lo que hace un difícil diagnóstico definitivo y una dificultad en el manejo posterior. Estos quistes se clasifican en cuatro subtipos: endoteliales, pseudoquiste, epiteliales y parasitarios. El manejo de un quiste suprarrenal se puede resumir en tres pilares fundamentales: descartar el estado funcional del quiste, evaluación de eventual malignidad por imágenes, y evitar las posibles complicaciones (hemorragia, infección), sobre todo en los quistes de gran tamaño. Se presenta el caso de una paciente con quiste suprarrenal izquierdo no funcionante asociado a dolor abdominal. Se realiza revisión de la literatura y se plantean los distintos diagnósticos y alternativas terapéuticas. Abstract in english Adrenal cyst is the commonest type of benign lesions of adrenal gland, althought is a very rare entity.

Adrenal Cyst have a broad differential diag [...] noses, rendering definitive diagnosis and subsequent management difficult. Are categorized into four subtypes: endothelial, pseudocyst, epithelial, and parasitic. This management paradigm may be summarized as: ruling out functional status of the cyst, evaluating chances of incidental malignancy by imaging, avoiding potential complications of surveillance (hemorrhage, infection), particularly in large cysts. A case of a patient with a left non-functioning adrenal cyst is reported, with abdominal pain. The diagnostic and therapeutic options are discussed and the literature is reviewed.

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.

Intracranial Extension of an Orbital Epidermoid Cyst.  

Science.gov (United States)

Epidermoid and dermoid cysts represent the most common cystic lesions of the orbit and commonly arise from bony sutures or the intradiplpoic space of orbital bones. Massive intracranial extension of an epidermoid cyst arising from the intradiploic space of an orbital bone is very rarely seen. We present a case of a 55-year-old male who was incidentally found to have massive intracranial extension of an intradiploic epidermoid cyst of the superolateral orbital bone with minimal symptoms. The cyst was completely excised via a pterional craniotomy and lateral orbitotomy by neurosurgery and oculoplastic surgery teams. The patient suffered no complications and is doing very well.

Testicular schistosomiasis.  

Directory of Open Access Journals (Sweden)

Testicular schistosomiasis is extremely rare, with only 12 cases reported. Reaching the diagnosis for this lesion that mimics malignant tumor is a great dilemma for the radiologist as well as the urologist. We report a case of testicular schistosomiasis from France that was managed conservatively. A 31- year-old Egyptian male presented to the outpatient clinic with primary infertility for 9 years. Physical examination revealed healthy male without any congenital malformations. Blood count and C-reactive protein level were normal. Hormonal tests were normal. Scrotal ultrasound showed small mass at the right testis. Scrotal exploration was carried out and frozen section results were schistosomiasis. He was given medical therapy, and further investigations were normal. A thorough evaluation must be carried out, and testicular schistosomiasis may be considered in patients living in endemic areas. We emphasize the lack of data to reach this diagnosis by radiological imaging.

Recurrent intramedullary epidermoid cyst of conus medullaris.  

LENUS (Irish Health Repository)

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

NMR imaging. Intracranial epidermoid and dermoid tumour  

Energy Technology Data Exchange (ETDEWEB)

Three epidermoid and two dermoid tumours, pathologically proven, were examined by NMR and CT scans. Although most brain tumours have a low signal with a long T/sub 1/, a dermoid cyst and one of the two components of the other dermoid tumour had a high signal and therefore a short T/sub 1/. All three epidermoid tumours had a low signal and a long T/sub 1/. Because of the high level contrast between some of the tumours and cerebrospinal fluid, NMR is helpful to detect the lesion. Neither of the liquid fluid levels in the tumour cysts or floating fat in the subarachnoid space was recognized in one patients, but the fine leakage of the content from the epidermoid cyst into the lateral ventricle was detected on a saturation recovery 1000 image in one case.

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.

Giant epidermoid cyst of the posterior neck.  

Science.gov (United States)

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

Sublingual epidermoid cyst: a case report  

Directory of Open Access Journals (Sweden)

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

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.

Quistes renales: concepto y clasificación Renal cysts: concept and classification  

Directory of Open Access Journals (Sweden)

Full Text Available Con la finalidad de poder ayudar a los estudiantes de medicina y médicos generales básicos, se hace una breve revisión sobre los quistes renales, tanto de los que constituyen una enfermedad por sí mismos como de los que pueden estar asociados a diferentes síndromes y los que pueden aparecer evolutivamente en el curso de una enfermedad renal. Conocer las causas principales que producen quistes renales es esencial para el correcto asesoramiento genético. Consideramos que esta clasificación, aunque no perfecta ni completa, puede ser útil en la práctica médica. En ella se trata de agrupar en primer lugar a las enfermedades con herencia dominante o recesiva, y además a los quistes asociados a síndromes malformativos, las alteraciones cromosómicas que pueden tener quistes renales y los quistes no genéticos que pueden ser congénitos o adquiridos.To help medical students and basic general physicians, a brief review is made on renal cysts, including those that are a disease by themselves, the associated with different syndromes, and the ones that may appear evolutively in the course of a renal disease. Knowing the main causes of renal cysts is essential for an appropriate genetic counselling. We consider that this classification, although it is neither perfect nor complete, may be useful in medical practice. An effort is made to group in it , in the first place, the diseases with dominant or recessive inheritance, the cysts associated with malformation syndromes, the chromosomal disorders that may have renal cysts, and the nongenetic cysts that may be congenital or acquired.

With a followup of 24 months 5 relapses took place, mainly in patients subjected to local excision of the lesion (p = 0,06 log-rank test). Conclusions. The epidermoid carcinoma of the penis is a tumoral lesion characteristic of advancedages that is diagnosed later and treated in not very aggressive way. Therefore it is frequent the advanced stadiums and the tumour relapses.

Malignant transformation of an epidermoid cyst in the cerebellopontine angle.  

Science.gov (United States)

Intracranial squamous cell carcinoma is extremely rare, with most of the cases arising from malignant transformation of an epidermoid or a dermoid cyst. The patient presented with facial weakness. Initial magnetic resonance imaging revealed a mass in the right cerebellopontine angle. A subtotal resection was performed via right retrosigmoid suboccipital approach. Histopathological findings were consistent with an epidermoid tumor. Five months later, the patient underwent gamma knife radiosurgery due to highly probable recurrent epidermoid tumor. Two years after, the patient's neurological deficit had been newly developed, and follow-up magnetic resonance imaging demonstrated a large contrast-enhancing tumor in the left cerebellopontine angle, which compressed the brainstem. After resection of the tumor, histopathological examinations revealed a squamous cell carcinoma probably arising from an underlying epidermoid cyst. We report a case of an epidermoid tumor in the cerebellopontine angle that transformed into a squamous cell carcinoma. PMID:23091675

High-density intracranial epidermoid tumors  

International Nuclear Information System (INIS)

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

Percutaneous testicular biopsy for indeterminate testicular lesions  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Ultrasound forms an important part of the assessment of the testicle. Nevertheless, there are a number of situations in which clinical and radiological assessment is unable to provide a definitive diagnosis of a testicular lump. In these situations, historically, either open biopsy or orchidectomy has been performed. Ultrasound-guided percutaneous testicular biopsy is an alternative, less invasive method of obtaining histological diagnosis. Here we describe the rationale, technique and potent...

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.

Isodense epidermoid cyst in the pineal region  

International Nuclear Information System (INIS)

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

Case of a spontaneously ruptured epidermoid cyst  

Energy Technology Data Exchange (ETDEWEB)

Intracranial fat-containing congenital tumors are characterized by negative absorption values on CT. We hereby report a case of an epidermoid cyst with subarachnoid free fats diagnosed preoperatively by CT. A 21-year-old female was admitted to our hospital because of continuous mild headache and nausea. At the time of admission, the results of her physical and neurological examinations were normal. CT, however, demonstrated multiple subarachnoid low-density spots and a suprasellar low-density area with high-density spots. In addition, there were negative absorption values (-12 -- -77), suggesting free fats. A spontaneously ruptured epidermoid or dermoid cyst was diagnosed on the basis of these findings. At surgery, a suprasellar tumor containing a yellowish, cheese-like material was confirmed. The patient made an uneventful recovery and was discharged 14 days after surgery. There have been several published reports of CT appearances of intracranial fat-containing tumors. However, spontaneously ruptured cases diagnosed by CT are rare. CT was found to be useful for the diagnosis of spontaneously ruptured cases of fat-containing tumors.

Epidermoid cyst causing hemifacial spasm epidermoid cyst in cerebellopontine angle presenting with hemifacial spasm.  

Science.gov (United States)

Hemifacial Spasm (HS) occurs idiopathically or secondary to the lesions compressing the root exit zone of the facial nerve symptomatically. Symptomatic HS is generally due to vascular compression. We report on a 23-year-old male with right sided HS for a month. Magnetic resonance imaging (MRI) of the brain revealed a well-demarcated epidermoid cyst in the right cerebellopontine cistern. It was hypointense on T1-weighted imaging, hyperintense on T2-weighted imaging without contrast enhancement, hyperintense on DWI, and slightly hypointense on ADC relative to the brain. Although it caused shifting of the pons and medulla to the left side and compression of the right cerebellar peduncles and fourth ventricle, the sole symptom of the patient was HS. Clinicians are advised to request MRI/scan for brainstem lesions from the patients with HS. Epidermoid cysts in cerebellopontine cistern may present with HS as the sole symptom. PMID:23188990

Intraspinal epidermoid cyst: diffusion-weighted MRI  

Energy Technology Data Exchange (ETDEWEB)

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

En las enfermedades intersticiales difusas,¿todos los quistes son realmente quistes? / Diffuse interstitial diseases: are all cysts real cysts?  

Scientific Electronic Library Online (English)

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

Spontaneous regression of an epidermoid cyst of the cavernous sinus.  

Science.gov (United States)

Epidermoid cysts are rare lesions in the pediatric population. The natural history of epidermoids is usually that of slow growth, although rupture and cases of malignant transformation have been reported. Spontaneous regression of an intracranial epidermoid cyst has not previously been described to our knowledge. We present a 3-year-old boy who presented with severe vertigo. MRI was performed which revealed a 2cm non-enhancing lesion in the right cavernous sinus. The lesion was T1-hypoinsense, T2-hyperintense, and with evidence of restricted diffusion, consistent with an epidermoid cyst. The patient was followed with annual MRI studies over the next 3years, demonstrating progressive reduction in the size of the lesion over time, with complete resolution after 3years. The child's symptoms also resolved during this period. Long-term follow-up imaging at 5years showed no evident lesion. To our knowledge, this is the first report documenting spontaneous regression of an intracranial epidermoid cyst. While isolated, this finding demonstrates the potential for involution of epidermoids and lends support to the clinical practice of careful observation of these lesions, especially when located in areas associated with high potential surgical morbidity. Importantly, the novelty of this observation suggests a need for further study to better elucidate the underlying mechanism of this regression. PMID:24736191

Penile Epidermoid Cyst Consisted of Multiple Foci: A Case Report  

Directory of Open Access Journals (Sweden)

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.

Rare frontal lobe intraparenchymal epidermoid cyst with atypical imaging.  

Science.gov (United States)

Epidermoid cysts are slow-growing benign tumors derived from ectodermal tissue that are hypothesized to have been inwardly displaced from the ectodermal surfaces during embryologic development. These cysts represent 1% to 2% of all intracranial tumors, and occur most commonly in the cerebellopontine angle, parasellar region, and subarachnoid spaces of the basal cisterns. Epidermoid cysts that are exclusively intraparenchymal are very rare, and can be difficult to diagnose as they often do not have classic radiologic findings, and share many similar radiologic features to other tumors such as astrocytomas, arachnoid cysts, dermoid cysts, and cavernomas. The authors present a patient with a rare intraparenchymal epidermoid cyst of the frontal lobe with atypical imaging features. PMID:22534617

Epidermoid Cyst of the Neck in an Elderly Patient  

Directory of Open Access Journals (Sweden)

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

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

Science.gov (United States)

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

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

Energy Technology Data Exchange (ETDEWEB)

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

Testicular cancer: an overview.  

Science.gov (United States)

Testicular cancer (TC) strikes men between the ages of 15 and 35. If detected early, this disease can be irradicated in virtually every patient. Unfortunately, several hundred men will die from this disease each year. Research has shown that men do not know the importance of testicular self-examination, and they are not knowledgeable about TC. Nurses should be able to discuss treatment modalities, side-effect management related to those treatments, and special issues dealing with sexuality, body image perception, and infertility.

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 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.

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

Surgical treatment of intradiploic epidermoid cyst treated as depression  

Directory of Open Access Journals (Sweden)

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

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

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.

Recovery of testicular blood flow following ligation of testicular vessels  

International Nuclear Information System (INIS)

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

A case report of testicular sparganosis misdiagnosed as testicular tumor.  

Science.gov (United States)

Sparganosis is a parasitic infestation of human by plerocercoid larvae. Sparganum is usually reported to be found in the subcutaneous tissues as well as other organs, including scrotum. However, testicular sparganosis is extremely rare, because of strong capsule of tunica albuginea. An urban-living 54-yr-old Korean man presented with left scrotal pain for 6 yr. Both testes look normal physically. Ultrasonography revealed poorly defined, heterogeneous mass with increased echogenicity in the left testis. This case was misdiagnosed as testicular tumor and underwent orchiectomy, but was diagnosed as testicular sparganosis by histopathology. Sparganosis should be included for differential diagnosis of testis tumor in countries where sparganosis is prevalent. PMID:25045238

Testicular Volume: Size Does Matter  

International Nuclear Information System (INIS)

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

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

A giant testicular teratoma.  

Directory of Open Access Journals (Sweden)

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

MRI of testicular disease  

International Nuclear Information System (INIS)

The value of T1-weighted sequences after intravenous administration of Gd-DTPA and of T2-weighted sequences was compared in 43 patients suspected of having scrotal abnormalities. T2-weighted sequences gave better demonstration of the tunica albuginea and better contrast between tumor and parenchyma. The two techniques were equally sensitive for demonstrating testicular tumors but orchitis was better demonstrated on the contrast enhanced sequences. Motion artifacts were less marked in the T1-weighted sequences with contrast enhancement. In selected cases, contrast enhancement may be a valuable addition to native protocols. Our experience has indicated that MRI provides specific findings in cases of orchitis which are clinically atypical; this facilitates the decision to conservative treatment and prevents unnecessary exploration of the testes.

Testicular obstruction: clinicopathological studies.  

Science.gov (United States)

Genital tract reconstruction has been attempted in subfertile men with obstructive azoospermia (370 patients) or unilateral testicular obstruction (80 patients), and in vasectomised men undergoing reversal for the first (130 patients) or subsequent (32 patients) time. Histopathological changes in the obstructed testes and epididymes, and immunological responses to the sequestered spermatozoa have been studied to gain insight into possible causes of failure of surgical treatment. The results of surgery have been assessed by follow-up sperm counts and occurrence of pregnancies in the female partners. The best results were obtained with vasectomy reversal (patency 90%, pregnancy 45%), even after failed previous attempts (patency 87%, pregnancy 37%). Epididymovasostomy gave good results with postinfective caudal blocks (patency 52%, pregnancy 38%), while postinfective vasal blocks were better corrected by total anatomical reconstruction (patency 73%, pregnancy 27%) than by transvasovasostomy (patency 9%, no pregnancies). Poor results were obtained with capital blocks (patency 12%, pregnancy 3%), in which substantial lipid accumulation was demonstrated in the ductuli efferentes; three-quarters of these patients had sinusitis, bronchitis or bronchiectasis (Young's syndrome). There is circumstantial evidence to suggest that this syndrome may be a late complication of mercury intoxication in childhood. After successful reconstruction, fertility was relatively reduced in those men who had antibodies to spermatozoa, particularly amongst the postinfective cases. Similarly, impaired fertility was found in men with unilateral testicular obstruction and antibodies to spermatozoa. Mononuclear cell infiltration of seminiferous tubules and rete testis was noted occasionally, supporting a diagnosis of autoimmune orchitis; although rare, this was an important observation as the sperm output became normal with adjuvant prednisolone therapy.

Crossed testicular ectopia  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese INTRODUÇÃO: A ectopia testicular cruzada (ETC) é uma anomalia rara, caracterizada pela descida de um testítulo no canal inguinal do lado oposto. Apresentamos um caso de ectopia cruzada do testículo direito, tratado por transposição extraperitoneal da gônada e orquipexia direita. CONCLUSÃO: Os conhec [...] imentos embriológicos e os achados cirúrgicos sugerem que a ETC seja uma conseqüência comum de vários fatores etiológicos, sobretudo fatores mecânicos, e pode causar persistência do ducto de Müller. Após extensa revisão da literatura,sugerimos uma classificação da ETC em 3 tipos: 1 - associada somente à hérnia inguinal; II associada a remanescentes mullerianos; III - associada a outras anomalias, sem remanescentes mullerianos. O tratamento inclui orquipexia trans-septal ou transposição trans-abdominal do testículo, pesquisa de remanescentes mullerianos e outras anomalias, e seguimento pós-operatório a longo prazo, devido a risco de malignização. Abstract in english Crossed testicular ectopia (CTE) is a rare anomaly, characterized by migration of one testis towards the opposite inguinal canal. Presented here is a case of crossed ectopia of the right testis, treated by extraperitoneal transposition of the gonad and right orchiopexy. Embriology and surgical findi [...] ngs suggest that CTE is a common consequence of many unclear ethiologic factors, specially mechanical ones, and can be associated with Muller duct persistence. Review of literature suggests a classification of CTE into 3 types: I - associated with inguinal hernia alone; II - associated with persistent mullerian remnants; III - associated with other anomalies without mullerian remnants. Treatment includes transeptal orchiopexy or extraperitoneal transposition of the testis, research for mullerian remnants and other anomalies, and long term postoperative follow-up, due to the risk of becoming malignant.

Neonatal Testicular Torsion; A Review Article  

Directory of Open Access Journals (Sweden)

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

Testicular microlithiasis and cryptorchidism a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Testicular microlithiasis (TM is an uncommon condition with reported prevalence of 0.6% in patients referred for scrotal ultrasound. Testicular microlithiasis was first reported by Priebe and Garret in 1970 and defined as multiple tiny calcification throughout the testis. The condition appears as characterstic small nonshadowing hyperechoic stippling foci in testicular parenchyma. Several associations have been reported with testicular microlithiasis.Considrable accrued evidence points to an association between testicular microlithiasis, intra tubular germ cell neoplasia and testicular tumor. This topic is of considerable attention to researchers. We recommend annual ultrasonic follow up and patient education about self- examination and bio-humeral evaluation for ruling out concurrent tumors.

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.

A case of a spontaneously ruptured epidermoid cyst  

International Nuclear Information System (INIS)

Intracranial fat-containing congenital tumors are characterized by negative absorption values on CT. We hereby report a case of an epidermoid cyst with subarachnoid free fats diagnosed preoperatively by CT. A 21-year-old female was admitted to our hospital because of continuous mild headache and nausea. At the time of admission, the results of her physical and neurological examinations were normal. CT, however, demonstrated multiple subarachnoid low-density spots and a suprasellar low-density area with high-density spots. In addition, there were negative absorption values (-12 ? -77), suggesting free fats. A spontaneously ruptured epidermoid or dermoid cyst was diagnosed on the basis of these findings. At surgery, a suprasellar tumor containing a yellowish, cheese-like material was confirmed. The patient made an uneventful recovery and was discharged 14 days after surgery. There have been several published reports of CT appearances of intracranial fat-containing tumors. However, spontaneously ruptured cases diagnosed by CT are rare. CT was found to be useful for the diagnosis of spontaneously ruptured cases of fat-containing tumors. (author)

[Anal epidermoid carcinoma: a rare incidence or a rare diagnosis?].  

Science.gov (United States)

Epidermoid cancer of the anus is a rare entity which represents 1-2% of all gastrointestinal tract cancers. Possible predisposing causes include smoking and sexual behaviour, particularly homosexual anal intercourse, chronic inflammation (Crohn, anal fistula, fissure, sepsis, hydradenitis suppurativa), and transmissible agents (human papillomavirus type 16 y 18, condylomata acuminata). Another factor is the genetic, which may be related to changes in chromosome 11 and the sort arm of chromosome 3. The aetiology of anal carcinoma is a multifactorial interaction between environmental factors. HPV infection, immune status and suppressor genes. We report on three cases of squamous cell carcinoma of the anus seen in our Unit of Proctology. One patient with widespread perianal hydradenitis suppurativa. Another one in a patient VIH+ with anal human papillomavirus infection, in situ cervix cancer and condylomata acuminata of the vulva and anus. A third case, a man with haemorrhoids. Is addition, constant irritation, chronic inflammatory changes, and repeated epithelial regeneration that accompany noninfectious conditions may be related to risk of anal epidermoid cancer. It is important that this cancer is kept in mind. It is unforgivable that a cancerous lesion that can be suspected in a simple inspection or rectal digital examination be attributed, to a benign anal condition. PMID:9115820

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

Directory of Open Access Journals (Sweden)

Full Text Available OBJECTIVE: To prospectively determine the prevalence of testicular microlithiasis in symptomatic patients who were referred for scrotal ultrasound examination and to evaluate the possible association of testicular microlithiasis with testicular cancer and other conditions such as cryptorchidism or history of ascending testis. MATERIALS AND METHODS: 391 men who were referred to our institutions between July 2002 and May 2005 for any type of symptoms from the testicles, underwent physical and scrotal ultrasound examination. The presence of testicular microlithiasis, the number of lesions and the involvement of both testicles in relation to the symptoms as well as the coexistence of other lesions were studied. RESULTS: Eighteen (4.6% of 391 men enrolled into the study had testicular microlithiasis. Two out of the eighteen patients (11% had concomitant testicular cancer, which was confirmed by pathological evaluation of the orchidectomy specimen. One of the patients with testicular microlithiasis presented a rising in biochemical tumor markers (LDH, and HCG and underwent orchidectomy one year later. Five of the remaining 373 (1.3% patients without microlithiasis were diagnosed with testicular cancer. Thirty six men reported having a history of ascending testis, but none of them was found with testicular cancer. Two cases of testicular torsion in a cryptorchid position had testicular microlithiasis, but the orchidectomy specimen (after surgery was negative for testicular cancer. The correlation between testicular cancer and testicular microlithiasis found in our study was statistically significant (p < 0.05. CONCLUSION: There seems to be an association between testicular microlithiasis and testicular cancer.

La baja incidencia de la enfermedad y la creencia errónea de que se trata de un proceso benigno y asintomático han contribuido al escaso interés por su conocimiento. Se realizó un estudio retrospectivo con revisión de los pacientes ingresados en el Servicio de Cirugía General y Digestiva del Hospital General de Castellón entre enero de 1990 y noviembre de 2005. Se diagnosticaron 4 quistes mesentéricos de los 34 355 ingresos en nuestro servicio. La mitad eran mujeres y la media de edad fue de 25 años.

Uno de los pacientes se complicó con una perforación espontánea del quiste y peritonitis. El tratamiento fue la exéresis quirúrgica en todos los casos. Las vías de abordaje fueron: 3 laparotomías y 1 laparoscopia. Únicamente un caso requirió resección intestinal por déficit en la vascularización. No hubo ninguna recidiva tras la cirugía. A pesar de la baja frecuencia de esta enfermedad, su conocimiento es necesario ya que se pueden presentar síntomas cuando el quiste ha crecido, así como complicaciones graves (hemorragia, perforación, obstrucción intestinal, malignización, etc., que se pueden prevenir con la intervención quirúrgica, incluso en los casos asintomáticos

Studies of testicular function after treatment for testicular tumor, 2  

International Nuclear Information System (INIS)

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

Testicular microlithiasis and cryptorchidism a case report  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Testicular microlithiasis (TM) is an uncommon condition with reported prevalence of 0.6% in patients referred for scrotal ultrasound. Testicular microlithiasis was first reported by Priebe and Garret in 1970 and defined as multiple tiny calcification throughout the testis. The condition appears as characterstic small nonshadowing hyperechoic stippling foci in testicular parenchyma. Several associations have been reported with testicular microlithiasis.Considrable accrued evidence points to an...

Intra-Abdominal Testicular Seminoma in a Woman with Testicular Feminization Syndrome  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We report a case of intra-abdominal testicular tumor in a 36-year-old married lady presenting with chief complaints of primary amenorrhea. The patient was later diagnosed with testicular feminization syndrome, a form of male pseudohermaphroditism. This testicular tumor was histologically proven as seminoma. Due to rarity, imaging findings in patients with testicular feminization syndrome and intraabdominal testicular tumor have been poorly documented. So far, only one case report had describe...

An appropriate clinical and radiographic exploration on the part of the dentist is enough to reach a presumptive diagnosis. The clinical and therapeutic considerations of each of these cysts are variable, so it is necessary to know their epidemiological behavior. The presumptive diagnosis, the size of the cyst and its relationship with neighboring anatomical structures will determine the type of treatment. The definitive diagnosis will be determined by the anatomical and pathological diagnosis.

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

International Nuclear Information System (INIS)

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

Epidermoid cyst radiologically mistaken as a left sided subpulmonic effusion.  

Science.gov (United States)

A 33-year-old female had a left sided chest pain for the last 3 months. Chest X-ray showed a left basal opacity. Computed tomography chest suggested a left sided subpulmonic effusion (17.5x12.2x13 cm) with thick enhanced walls with marked collapse of the left lower lobe and displacement of the heart and mediastinum to the right side. Trial of thoracocentesis was done and it was positive. Trial of intercostal tube insertion was done with a sense of very thick pleura and the patient developed a vasovagal attack. Accordingly, exploratory thoracotomy was decided. Intraoperative assessment showed a huge anterosuperior mediastinal cyst attached to the pericardium and was successfully resected. The pathological findings were compatible with epidermoid cyst. PMID:17670071

Ultrasonographic features of testicular tumors  

International Nuclear Information System (INIS)

Objective: To evaluate the ultrasonography in diagnosis of testicular tumors. Methods: Findings of high-frequency ultrasound and CDFI were retrospectively studied in 34 cases of testicular tumors that were confirmed by post-surgical pathology. Results: The enlarged testes with space-occupying lesions were detected in all cases. The benign tumors had showed clear and regular margin in 9 cases. And there was no signal or hypo-signal of blood flow within and surrounding the lesions on CDFI. Blurred and irregular margin of malignant tumors is revealed in 25 cases. Blood flow and in some cases, abundant blood flow within and surrounding the tumors were shown on CDFI in those cases. Conclusions: Ultrasonography is a non-invasive and intuitive examination providing quality imaging. High-frequency ultrasonography and CDFI are valuable in differentiating the benign testicular tumors with malignant ones

Testicular metastasis from adenocarcinoma of the esophagus.  

Science.gov (United States)

We report the case of a 61-year-old patient, operated on for adenocarcinoma of the esophagus in 2002, who presented in 2007 with a hydrocele and palpable mass of the right testis. Operative exploration and orchiectomy were performed. Histopathology revealed a testicular and epididymidal metastasis from the esophageal adenocarcinoma. Only a few testicular metastases have been reported from gastrointestinal cancers. No case of testicular metastasis from esophageal cancer, including Barrett's carcinoma has been reported. In most cases, the testicular tumor was accompanied by a hydrocele. Therefore, cancerous and metastatic lesions should be considered in the management of hydrocele and testicular masses.

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

International Nuclear Information System (INIS)

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

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.)

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

Directory of Open Access Journals (Sweden)

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

Hypothalamic-pituitary-testicular system following testicular X-irradiation  

International Nuclear Information System (INIS)

Testes of adult, male rats were exposed to a total dose of 1500 R of X-irradiation. Testicular weight decreased from day 8 after X-ray treatment. This decrease was, however, precded by an increment of the testis weight on day 4 following treatment. X-ray treatment of testes was associated with significant increase in serum FSH. Testicular irradiation had, however, no effect on ventral prostate and seminal vesicles weights. Serum testosterone increased only on day 1, 2 and 4 after irradiation, while serum LH levels tended to increase from day 8 post-irradiation. These changes were not significant, however, when compared with non-irradiated controls. At 7, 13 and 20 days following 1500 R of bilateral, testicular X-irradiation, the hypothalamic-pituitary unit was still capable of responding to exogenous gonadotrophin releasing factor. Serum FSH may in male rats be regulated at least partly by circulating steroids of testicular origin and partly by an unknown factor of non-interstitial cell nature. (author)

Perspectives for the treatment of epidermoid oesophageal cancer; Perspectives actuelles dans le traitement du cancer epidermoide de l`oesophage  

Energy Technology Data Exchange (ETDEWEB)

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

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

Abstract in english Dentigerous cysts are a casual finding in most of cases, in general discovered in investigation of a not eruption of permanent tooth. These occupy the second place in appearance frequency in maxillaries after radicular cyst. When maxillary sinus is invaded by these cysts, symptoms usually appear lat [...] e in the process. These could include facial pain, paresthesia as consequence of pressure on nerve, headache, trismus, taste disorders and nasal congestion. Due the infrequent of the maxillary location and the short age of patient we reviewed the more recent of bibliography on this subject and to present the clinical case of other female patient aged 17 diagnosed with and treated by dentigerous cyst in such location, emphasizing on the significance of a appropriate diagnosis and establishment of a therapy in accord in each case

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

Digital Repository Infrastructure Vision for European Research (DRIVER)

El quiste mesentérico es una enfermedad poco frecuente, cuya importancia ha sido menospreciada en demasiadas ocasiones en la literatura médica. La baja incidencia de la enfermedad y la creencia errónea de que se trata de un proceso benigno y asintomático han contribuido al escaso interés por su conocimiento. Se realizó un estudio retrospectivo con revisión de los pacientes ingresados en el Servicio de Cirugía General y Digestiva del Hospital General de Castellón entre enero de 1990 y...

Primary testicular NHL mimicking testicular carcinoma on FDG PET  

International Nuclear Information System (INIS)

A 57-year-old man presented with left testicular swelling. An ultrasound showed a 6cm mass in the left testis and 3 small nodules in the right testis. A CT scan showed left para-aortic nodes and no nodal disease elsewhere. An excisional biopsy of the left testis was followed by an FDG PET scan. A right orchidectomy was then performed. Histology showed diffuse large B cell lymphoma involving both testes and the left spermatic cord. Testicular lymphoma and carcinoma cannot be distinguished using FDG-PET thus emphasizing the principle that FDG-PET should be used as a tool for staging, not for primary diagnosis and that the nature of the pathological condition causing FDG uptake has to be confirmed with biopsy/histology Copyright (2006) Blackwell Publishing Asia Pty Ltd

Testicular manifestation of a transformed mycosis fungoides  

Directory of Open Access Journals (Sweden)

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

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.

Referred for endoscopic retrograde cholangiopancreatography, a study that was omitted from control abdominal ultrasound suggestive of choledochal cyst. New requested from magnetic resonance, which displayed no reports cyst and bile duct dilation and terminal hepatocoledoco related aspects. Expectant management is maintained. The patient remains asymptomatic, with reassessment 3 months later. The abdominal ultrasound revealed: fusiform dilatation of the bile duct in its entirety, a finding compatible with type I choledochal cyst Resection was performed, the cyst, cholecystectomy and reconstruction of the bile duct through a hepato-jejunostomy Roux en Y no complications. Liver biopsy reported normal tissue. We conclude that the use of noninvasive imaging tests such as ultrasound is the method of choice due to its sensitivity to determine the presence of cyst and to demonstrate the anatomy of the pancreatic’duct.

[Cryopreservation of testicular tissue in children].  

Science.gov (United States)

The toxicity of cancer therapies can affect all organs and tissues. Some treatments damage spermatogonial stem cells (SSCs), with a risk of infertility. Storage and reimplantation of frozen testicular tissue is a recent approach tofertilitypreservationfor young boys. However, thawed frozen prepubertal testicular tissue must undergo a maturation process to restore sperm production. This process, currently being studied in animal models, can be achieved by in vivo transplantation of SSCs into seminiferous tubules or by testicular grafting, possibly following in vitro maturation.

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

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

Estrogen regulation of testicular function  

Directory of Open Access Journals (Sweden)

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

Unusual site and uncommon presentation of epidermoid cyst: a rare case report and review of literature  

Science.gov (United States)

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

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

Testicular microlithiasis and associated testicular malignancies in childhood: A systematic review.  

Science.gov (United States)

The aim was to perform a systematic review to evaluate the published data on testicular microlithiasis (TM) in the pediatric population and to explore the association of TM with testicular malignancy as well as to propose guidelines to aid decision making on pediatric patients with TM. Outcome data for pediatric TM should be interpretated with caution due to the poor quality evidence available. Whilst the link with testicular neoplasms is undisputed (<5%) active screening programmes require robust evidence to support their wider deployment. Testicular self-examination though would appear advisable for all patients with testicular microlithiasis. Pediatr Blood Cancer 2015;62:385-388. © 2014 Wiley Periodicals, Inc. PMID:25417839

Muco-epidermoid and adenoid cystic carcinomas of the tracheobronchial tree.  

Science.gov (United States)

Muco-epidermoid and adenoid cystic carcinomas of the respiratory tree are uncommon and warrant attention because of controversy and uncertainty surrounding their behaviour and management. Ten cases of these tumours are detailed, with emphasis on approach to management. Careful attention should be paid to histological grading of muco-epidermoid carcinomas. Low grade tumours, completely excised, behave the best. Adenoid cystic carcinomas are slow-growing, relentlessly progressive tumours and difficult to eradicate locally. Surgery remains the best therapeutic tool available. PMID:1850979

Involvement of the anterior commissure in stage I and II epidermoid carcinoma of the glottic larynx  

International Nuclear Information System (INIS)

This paper compares the results of primary irradiation of stage I and stage II epidermoid carcinoma of the glottic larynx with and without involvement of the anterior commissure (AC). Fifty-five patients with stage I and II epidermoid carcinoma of the glottic larynx treated at UCLA from 1987 to 1988 were retrospectively reviewed. Twenty-six had involvement of the AC. Patients were stratified by the AJCC staging system: the AC-negative group had 13 T1a and five T1b stage I and eight stage II lesions. The basis for stage II classification was similar in both groups

Quiste renal gigante. Presentación de un caso / Giant renal cyst. Presentation of a case

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

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 mediastined 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

A avaliação ultrassonográfica dos testículos mostrou-se um método eficiente, capaz de detectar as mudanças no parênquima testicular ao longo do tempo, e como ferramenta alternativa para diferenciação de condições normais e patológicas em caprinos. Abstract in english The purpose of this study was to observe changes in the testicular parenchyma of male goats. Changes were observed in terms of goat age, evaluating the echotexture and ultrasound viability in the testicles. Four animals were used, ranging from six to 13 months of age. The echographic examinations we [...] re performed every 15 days to assess echotexture of the testicle. The testicular parenchyma appeared moderately echogenic and homogeneous. Similar results were observed in testicular echotexture during the evaluation period. The highest results appearing during the eighth month of age, when the testicular volume was also highest; such changes were related to the regional photoperiod. The ultrasound evaluation of the testicles was shown to be an effective method, ultimately capable of detecting changes in testicular parenchyma over time, being an alternative to differentiation normal and pathological conditions in goats.

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Overview of Pediatric Testicular Tumors in Korea  

Science.gov (United States)

Prepubertal testicular tumors are rare compared with postpubertal testicular tumors. The incidence of prepubertal testicular tumors peaks at 2 years of age, tapers off after 4 years of age, and then begins to rise again at puberty. Prepubertal and postpubertal testicular tumors show many differences, including the typical tumor histology, molecular biological differences, and the malignant potential of tumors at different ages. Pediatric testicular tumors are classified as benign or malignant on the basis of their clinical behavior and histologically are divided into germ cell and gonadal stromal (nongerm cell) tumors. Many histological and biological studies have further confirmed the distinct nature of prepubertal and postpubertal testicular tumors. These differences have led to various management strategies for prepubertal and postpubertal tumors. Because overall about 75% of prepubertal testicular tumors are benign, a testis-sparing approach is becoming more common in children. Orchiectomy and observation with very selective use of chemotherapy has become the standard approach when a malignant tumor is identified. Retroperitoneal lymph node dissection and radiation therapy play very limited roles. PMID:25512812

Tumor canceroso testicular: Seminoma clásico  

Directory of Open Access Journals (Sweden)

Full Text Available El tumor canceroso tipo seminoma es el cáncer testicular más frecuente, afecta con mayor frecuencia a las personasde una edad media de 50 años. El seminoma presenta factores de riesgo como criptorquidia, infertilidad y antecedentes familiares de primer grado con cáncer. La estadificación determina la extensión de la invasión hacia órganos vecinos; TNM (Tumor, Nódulo, Metástasis. El diagnóstico se realiza por la clínica, se observa una masa crecientede gran volumen, pero también se usa Marcadores Tumorales; como la Alfa feto proteína, la cual es negativa siempre para seminoma y B Gonadotrofina Coriónica Humana, la cual con muy poca frecuencia está elevada. Entre los métodos de imagen que se usan están la Radiografía de tórax, Tomografía de abdomen y pelvis para descartar metástasis. Se presenta un caso de un paciente de 52 años de edad, con una masa voluminosa testicular- indolora, de unos 7 años de evolución que desde hace 2 meses presenta puntos de hemorragia externa. Al examen físico presenta una masa de 18 por 15 cm, con un punto de hemorragia en la región escrotal y secreción purulenta en el prepucio, posteriormente se procede al tratamiento adecuado.

Testicular function after renal transplantation.  

Science.gov (United States)

Gonadal function was assessed in seventeen adult male renal transplant recipients, with well established good homograft function, for a mean of 4.9 years. Patients were assessed clinically and by measurement of basal concentrations of FSH, LH, prolactin, testosterone and oestradiol, FSH and LH responses to bolus injections of LHRH and semen analysis. Retrospectively all had symptoms consistent with marked hypogonadism prior to transplantation but in nine out of sixteen this was reversed with transplantation. Residual hypogonadism was evident in seven of sixteen patients and correlated with duration of haemodialysis longer than 1 year (P less than 0.01). Even among patients with clinically normal gonadal function, defects in the hypothalamic--pituitary--testicular axis remained. Elevated basal serum FSH, excessive FSH responses to LHRH and lowered basal serum testosterone were found. In the group with residual hypogonadism more marked changes, including elevated basal LH and excessive LH responses to LHRH, were also found. Fertility was recorded in two men on three occasions since transplantation. Sperm counts were normal in five and abnormal in four patients. Testicular volume and sperm density were inversely correlated with basal and stimulated FSH and LH levels. PMID:6796296

Ectopia testicular cruzada: Caso clínico  

Directory of Open Access Journals (Sweden)

Full Text Available Objetivos: Presentación de un paciente con ectopia testicular cruzada. Métodos: Se presenta la historia clínica del paciente, el resultado del ultrasonido abdominal e inguinal y los hallazgos de la exploración quirúrgica.. Resultados: Pre-escolar de 6 años de edad, quien consultó por presentar criptorquidia bilateral. En el examen físico no se encontró el testículo derecho en la bolsa escrotal ni en el canal inguinal. El testículo izquierdo estaba ubicado en el tercio inferior del canal inguinal. El ultrasonido inguino-escrotal y abdominal mostró el testículo izquierdo retenido en el canal inguinal y ausencia del testículo derecho. Se practicó intervención quirúrgica comprobándose ausencia del testículo derecho y de integrantes del cordón espermático, tanto a nivel del canal inguinal como en el retroperitoneo de ese lado. En el canal inguinal izquierdo se encontró doble cordón espermático, con proceso vaginal común para ambos testículos, los cuales estaban ubicados en el tercio inferior del canal inguinal. Se realizó liberación del proceso vaginal, separación de los cordones espermáticos y descenso de los testículos por el lado izquierdo, con transposición del septum inter-escrotal y pexia de ambas bolsas escrotales. Se comprobó evolución satisfactoria un año después de la intervención. Conclusiones: La ectopia testicular cruzada es una anomalía infrecuente del descenso testicular. El diagnóstico del caso que presentamos fue transoperatorio, al realizar la orquidopexia izquierda. Ambos testículos fueron descendidos a sus respectivas bolsas escrotales, con evolución satisfactoria un año después de la intervención.Objectives: To present a patient with transverse testicular ectopia. Methods: The patient’s clinical history, the abdominal and inguinal ultrasound study, and the surgical findings are presented. Results: This is a 6-years-old school-boy, who was admitted because of bilateral undescended testes. His right testicle was absent from his scrotal sac and from the inguinal canal. The left testicle was located in the lower end of the inguinal canal. Inguinal and abdominal ultrasound study showed absent right testis, and the left testicle located in the inguinal region. At surgery, the right testis was not found in the inguinal canal, neither in the retroperitoneal space. Double vas deferens, and a unique vaginalis processus were found, and both testes were located lower in the left inguinal canal. The vaginalis processus was liberated, the vas deferens were set apart, and both testes were descended through the left side. Transposition of the inter-scrotal septum and orchiopexy of both scrotal sacs was performed. Satisfactory evolution was confirmed one year after surgical intervention. Conclusions: Transverse testicular ectopia is a rare condition. The case from this presentation was diagnosed when the surgical intervention was performed to correct the left cryptorchid testis. Both testes were descended to their respective scrotal sacs. Satisfactory evolution was confirmed one year after surgery.

Testicular gametogenic and steroidogenic activities in cyclophosphamide treated rat: a correlative study with testicular oxidative stress.  

Science.gov (United States)

The present work examined the changes in testicular activities in relation to testicular oxidative stress in cyclophosphamide as well as human chorionic gonadotrophin (hCG) co-treated cyclophosphamide treated Wistar strain rats. Testicular activities were evaluated by the quantification of spermatogenesis and by the measurement of steroidogenic key enzyme activities along with plasma levels of testosterone. Testicular oxidative stress in relation to cyclophosphamide treatment was monitored by the study of products of free radicals like conjugated dienes and malondialdehyde (MDA) as well as the activity of testicular antioxidant enzymes like peroxidase and catalase. Cyclophosphamide treatment at the dose of 5 mg/kg body weight/day for 28 days resulted a significant diminution in the activities of testicular delta 5, 3 beta-hydroxysteroid dehydrogenase (delta 5, 3 beta-HSD), 17 beta-hydroxysteroid dehydrogenase (17 beta-HSD) activities, plasma level of testosterone along with significant reduction in the number of germ cells at stage-VII of spermatogenesis. Levels of testicular MDA and conjugated dienes both were elevated whereas testicular peroxidase and catalase activities both were inhibited significantly in cyclophosphamide treated rats in comparison to control. After hCG co-administration at the dose of 5 I.U./kg body weight/day for 28 days in cyclophosphamide treated rats resulted a significant protection in the activities of testicular peroxidase and catalase along with significant decrease in the levels of MDA and conjugated dienes to the control level. Moreover, the testicular steroidogenic key enzyme activities and spermatogenesis along with plasma levels of testosterone were restored to the control level. Therefore, it may be concluded that there is a correlation between testicular steroidogenic activities as well as spermatogenesis and testicular oxidative stress in cyclophosphamide treated rats. Moreover, as restoration of plasma testosterone to the control level is noted in hCG co-treated cyclophosphamide treated rat, therefore, the results suggest that testosterone may be the key regulator for this correlation.

Testicular cancer: addressing the psychosexual issues.  

LENUS (Irish Health Repository)

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

Carcinoma in situ in testicular biopsies.  

Science.gov (United States)

Carcinoma in situ of the testis is an abnormality of the seminiferous epithelium characterized by aneuploid cells with clear cytoplasm located along the tubular basement membrane or in the lumina of tubules. Morphological, cytogenetic, and histochemical features of this anomaly are presented. An adequate fixation of testicular tissue samples is necessary for correct diagnosis. The fact that approximately 50% of carcinoma in situ may develop into malignant germ cell tumours of the testis in 5 years and the investigations of the testicular tissue adjacent to these tumours support the malignant nature and invasive potential of testicular carcinoma in situ. The incidence of carcinoma in situ in persons at risk is reviewed. PMID:2700185

Factors Influencing Rate of Testicular Salvage in Acute Testicular Torsion at a Tertiary Pediatric Center  

Science.gov (United States)

Introduction Studies have demonstrated that variables other than duration of symptoms can affect outcomes in children with acute testicular torsion. We examined demographic and logistical factors, including inter-hospital transfer, which may affect outcomes at a tertiary pediatric referral center. Methods We reviewed charts of all pediatric patients with acute testicular torsion during a five-year period. Data were collected regarding age, insurance type, socioeconomic status, duration of symptoms prior to presentation, transfer status, time of day, time to surgical exploration, and testicular salvage. Results Our study included 114 patients. Testicular salvage was possible in 55.3% of patients. Thirty-one percent of patients included in the study were transferred from another facility. Inter-hospital transfer did not affect testicular salvage rate. Time to surgery and duration of pain were higher among patients who underwent orchiectomy versus orchidopexy. Patients older than eight years of age were more likely to undergo orchidopexy than those younger than eight (61.5% vs. 30.4%, p=0.01). Ethnicity, insurance type, or time of day did not affect the testicular salvage rates. On multivariate analysis, only duration of symptoms less than six hours predicted testicular salvage (OR 22.5, p<0.001). Conclusion Even though inter-hospital transfer delays definitive surgical management, it may not affect testicular salvage rates. Time to presentation is the most important factor in predicting outcomes in children with acute testicular torsion.

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 3(rd) to 5(th) 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.

[The cytological diagnostics of dysplasia and epidermoid carcinoma of the cervix in studying the nucleolar-organizing regions of chromosomes].  

Science.gov (United States)

The study of the nucleolar-organizing regions of chromosomes in the cells of dys-plastically modified squamous epithelium and epidermoid cancer of cervix was carried out. The successive increase of quantita-tive content of main morphofunctional types of nucleoli is established including active compact and transient nucleolonemic-compact ones in accordance with in-crease of dysplastic modifications and appearance of signs of epidermoid cancer of cervix. The dominance of percentage content of large argyrophilic granules in nu-cleoli of nucleolonemic type under epidermoid cancer of cervix as compared with dysplasia is established. The algorithm of differentiating cytological diagnostics of the degree of dysplasia and epidermoid cancer of cervix is developed. This algo-rithm reflects the degree of structural functional modifications of nucleolar-organizing regions of chromosomes. PMID:23305016

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

DEFF Research Database (Denmark)

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

[Testicular torsion: a tricky diagnosis].  

Science.gov (United States)

In common urological practice, testicular torsion is one of the most serious emergencies. Consequences can be devastating for the patient, both physically and psychologically. The primary care physician should be able to quickly identify the pathology and refer immediately the patient to a center with surgical facilities. Rapid diagnosis provides the best chances to save the patient's testicle, which may suffer irreversible damage as soon as 6 hours after the onset of the symptoms. History and clinical examination remain the cornerstones of the diagnosis, and are often sufficient to select patients who need surgical exploration. If time allows it, Doppler Ultrasound can often help distinguish torsion from other scrotal conditions, but cannot be considered as a 100% diagnostic tool. PMID:22232870

Segmental testicular infarction following cysto-prostatectomy  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Segmental (partial) testicular infarction is a very rare condition of unknown cause in more than 70% of cases. Several predisposing conditions have been described, but to our knowledge, this is the first documented case and often overlooked complication occurring as a result of cysto-prostatectomy. It usually presents in an acute manner resembling testicular torsion or epididymo-orchitis and is confirmed using ultrasonography. In some cases, it may present insidiously with no pain and ...

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish INTRODUCCIÓN Y OBJETIVOS: Los tumores vesicales con un patrón morfológico no transicional, constituyen un reto diagnóstico al patólogo y terapéutico al urólogo, pues aunque son poco frecuentes (menos del 5% de los tumores malignos de vejiga), presentan un comportamiento biológico diferente que oblig [...] a a un abordaje terapéutico particular. 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.

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

Energy Technology Data Exchange (ETDEWEB)

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

Quiste óseo aneurismático mandibular de tipo sólido Mandibular solid aneurysmal bone cyst  

Directory of Open Access Journals (Sweden)

Full Text Available El quiste óseo aneurismático sólido es una lesión ósea benigna muy infrecuente de la que no existe consenso en relación a su origen etiopatogénico. Presenta características clínicas, radiológicas e histológicas inespecíficas, por lo que los estudios ultraestructurales son fundamentales para su diagnóstico y clasificación. El diagnóstico diferencial es extenso e incluye múltiples lesiones óseas como el granuloma reparativo de células gigantes e incluso tumores malignos como el osteosarcoma. El tratamiento de elección es la cirugía conservadora. La recidiva se debe fundamentalmente a la extirpación incompleta.Solid aneurysmal bone cyst is a rare benign bone lesion for which no consensus exists regarding its origin. It has nonspecific clinical, radiological and histological features so ultrastructural studies are essential for diagnosis and classification. The differential diagnosis is extensive and includes a variety of bone lesions, such as giant cell reparative granuloma, and even malignant tumors like osteosarcoma. The treatment of choice is conservative surgery. Recurrence is due mainly to incomplete resection.

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

Directory of Open Access Journals (Sweden)

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

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)

Atypical appearance of epidermoid cyst in tongue’s ventral surface  

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Directory of Open Access Journals (Sweden)

Full Text Available Cystic disease of the spleen is not frequently encountered in surgical practice. It is broadly classified as parasitic and non-parasitic, the latter being a rare entity. In this case report, an epidermoid cyst of spleen led to acute abdomen in young age pregnant woman is presented.A 26-year-old woman with 15 weeks gestational age second pregnancy referred to emergency ward with left upper quadrant pain and tenderness that ultra sonography revealed large cyst (100?110mm with internal echo in spleen in favor of hydatic cyst or abscess. The patient was managed medically for one week but developed her abdominal pain, epigastric fullness, anorexia and fever. New sonography was done for her and large cyst was detected in spleen (120?110mm. She had severe pain accompanied with anorexia and vomiting. Fetus was normal in sonography. Exploratory laprotomy with splenectomy was performed. Splenomegaly (200?130?90mm with a cyst without any adhesion and inflammation was detected. Histopathology examination showed epidermoid cyst of spleen. (140?10?90mm. Though splenic epidermoid cyst is an uncommon entity, it should be considered in the differential diagnosis of an abdominal mass in a young individual. An attempt should be made to preserve the spleen provided there is adequate parenchyma otherwise splenectomy is the rule.

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

International Nuclear Information System (INIS)

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

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.

Tratamiento de los carcinomas epidermoides orales y orofaringeos mediante láser de CO2 / Treatment of oral and oropharyngeal epidermoid carcinomas by means of CO2 laser  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Introducción: El efecto de la amplia longitud de onda del láser de CO2 es la vaporización térmica de los tejidos, consiguiendo una máxima concentración de energía con una mínima penetración en los mismos. En el campo de la cirugía oral generalmente se emplea para el tratamiento de los pequeños tumor [...] es mucosos de la cavidad oral y la orofaringe, por la escasa morbilidad que produce y la ausencia de necesidad reconstructiva del defecto creado. Objetivo: Analizar la evolución postoperatoria, en los pacientes tratados por carcinomas epidermoides orales y orofaringeos, tras la resección mediante láser de CO2. Compararla con la de los pacientes tratados mediante métodos quirúrgicos convencionales realizando la reconstrucción a través de la sutura directa o el empleo de colgajos locales, regionales o a distancia. Diseño del estudio: Estudio de carácter prospectivo que incluye a 70 pacientes tratados por carcinomas epidermoides orales y orofaringeos. 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. Abstract in english Introduction: The effect of the wide long-wave CO2 laser is the thermal vaporization of the tissues, getting a maximum energy concentration with a minimum of tissue penetration. In oral surgery, it is generally used for the treatment of oral and oropharyngeal small mucous tumors, due to the scarce m [...] orbidity that takes place and the absence of reconstructive necessity. 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.

Global incidence and outcome of testicular cancer  

Directory of Open Access Journals (Sweden)

Full Text Available Thurkaa Shanmugalingam,1 Aspasia Soultati,2 Simon Chowdhury,2 Sarah Rudman,2 Mieke Van Hemelrijck11King’s College London, School of Medicine, Division of Cancer Studies, Cancer Epidemiology Group, London, UK; 2Department of Oncology, Guy’s and St Thomas’ NHS Foundation Trust, London, UKBackground: Testicular cancer is a rare tumor type accounting for 1% of malignancies in men. It is, however, the most common cancer in young men in Western populations. The incidence of testicular cancer is increasing globally, although a decline in mortality rates has been reported in Western countries. It is important to identify whether the variations in trends observed between populations are linked to genetic or environmental factors.Methods: Age-standardized incidence rates and age-standardized mortality rates for testicular cancer were obtained for men of all ages in ten countries from the Americas, Asia, Europe, and Oceania using the Cancer Incidence in Five Continents (CI5plus and World Health Organization (WHO mortality databases. The annual percent change was calculated using Joinpoint regression to assess temporal changes between geographical regions.Results: Testicular cancer age-standardized incidence rates are highest in New Zealand (7.8, UK (6.3, Australia (6.1, Sweden (5.6, USA (5.2, Poland (4.9, and Spain (3.8 per 100,000 men. India, People’s Republic of China, and Colombia had the lowest incidence (0.5, 1.3, and 2.2, respectively per 100,000 men. The annual percent changes for overall testicular cancer incidence significantly increased in the European countries Sweden 2.4%, (2.2; 2.6; UK 2.9%, (2.2; 3.6; and Spain 5.0%, (1.7; 8.4, Australia 3.0%, (2.2; 3.7, and People’s Republic of China 3.5%, (1.9; 5.1. India had the lowest overall testicular cancer incidence -1.7%, (-2.5; -0.8. Annual percent changes for overall testicular cancer mortality rates were decreasing in all study populations, with the greatest decline observed in Sweden -4.2%, (-4.8; -3.6 and People’s Republic of China -4.9%, (-6.5; -3.3.Conclusion: Testicular cancer is increasing in incidence in many countries; however, mortality rates remain low and most men are cured. An understanding of the risks and long-term side effects of treatment are important in managing men with this disease.Keywords: testicular cancer, global, incidence, mortality

Testicular Vasculitis – Literature Review and Case Report in Queensland  

Digital Repository Infrastructure Vision for European Research (DRIVER)

A 21-year-old male presented with acute onset, sharp right sided testicular pain. The testicle was removed with a histological diagnosis of testicular vasculitis. Anti-neutrophil cytoplasmic antibodies were negative. Although rare, males who present with acute onset pain should be screened for testicular vasculitis with a scrotal ultrasound and blood investigations including tumor markers and anti-neutrophil cytoplasmic antibodies.

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.

Prognóstico de tumores testiculares germinativos  

Directory of Open Access Journals (Sweden)

Full Text Available OBJETIVO: Investigar as características e a evolução de homens adultos portadores de tumores germinativos do testículo. MÉTODOS: Estudamos as características e a evolução 29 pacientes tratados (14 seminomas e 15 não seminomas. O tempo médio de seguimento foi de 56 meses para os seminomas e de 40 meses para os não seminomatosos. Todos foram submetidos a orquiectomia. Nos estádios II e III associou-se radioterapia para os seminomas, e quimioterapia e linfadenectomia para os não seminomatosos. RESULTADOS: As queixas mais freqüentes foram aumento de volume testicular (57% e dor (30%. Nos seminomas a idade média foi de 41,2 anos e nos não seminomas foi de 29,2 anos. Antecedente de criptorquidia foi assinalada em 28,5% dos seminomas e em 15,5% dos não seminomatosos. As proporções respectivas de estádios I, II e III foram de 79%, 14% e 7% em seminomas, e 40%, 27% e 33% em não seminomas. Os seminomas não provocaram elevação dos marcadores AFP ou b-HCG enquanto os não seminomatosos elevaram esses marcadores respectivamente em 46,6% e 33,3% dos casos. Morte pela doença ocorreu em 1 caso de seminoma e 3 de não seminomas, mas não houve diferença na sobrevida entre os grupos. CONCLUSÃO: A criptorquidia continua sendo um fator predisponente importante na etiologia dos tumores germinativos. Apesar dos tumores não seminomatosos se apresentarem em estádios mais avançados a sobrevida dos pacientes não difere da apresentada pelos portadores de seminomas.

Se le practicó orquiectomía por vía inguinal siendo diagnosticado de metástasis testicular de carcinoma vesical de alto grado. y revisión de la literatura publicada al respecto. Resultados: Supervivencia libre de enfermedad a los 12 meses de la orquiectomía. Conclusiones: El tumor testicular metastático excluyendo leucemias y linfomas es extremadamente raro. La presencia de metástasis testiculares supone una diseminación metastásica a otros niveles y por ello la Quimioterapia podría mejorar el pronóstico. Abstract in english Objective: To report a rare case of testicular metastasis secondary to an infiltrative transitional cell carcinoma years after radical surgery. Methods: Case Report: 71-year-old male patient with history of infiltrative bladder tumor, status post radical cystoprostatectomy with urethrectomy. Seven y [...] ears after surgery he presents with pain and swelling in the right testicle. Inguinal orchyectomy was carried out with the pathologic diagnosis of testicular metastasis of a high-grade transitional cell carcinoma. We perform a bibliographic review. Results: The patient is disease-free twelve months after orchyectomy. Conclusions: Apart from leukemia and lymphoma, testicular metastases are extremely rare. The existence of testicular metastases means a metastatic dissemination to other organs, therefore chemotherapy could improve prognosis.

Segmental testicular infarction following cysto-prostatectomy  

Directory of Open Access Journals (Sweden)

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

Ultrasonographic diagnosis of torsion of testicular appendages  

International Nuclear Information System (INIS)

To determine the efficacy of ultrasound in boys presenting torsion of a testicular appendage. A series of 30 boys with acute scrotal pain due to torsion of a testicular appendage was studied. Nine patients underwent surgery. The clinical findings and course in the remaining 21 suggested the presence of this abnormality. All of them underwent conventional and color Doppler ultrasound using a 7.5 MHz transducer. In 15 boys, ultrasound images depicted the affected appendage as a mass between the epididymal head and the testicle. In 13 cases, only signs of a inflammatory reaction, with enlargement of the epididymal head and tunicas presenting hyperflow and hydrocele, mimicking acute epididymities. In two cases, the images were normal. There is no definitive, distinguishing ultrasound image corresponding to testicular appendage torsion. Therefore, this diagnostic technique should be accompanied by clinical assessment. (Author) 14 refs

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

Directory of Open Access Journals (Sweden)

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

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.

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.

Testicular microlithiasis in paediatric age; Microlitiasis testiculares en la edad pediatrica  

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.

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

El período de seguimiento fue de 28 meses, con una recidiva de 3,5%. No hubo mortalidad en esta serie. El costo del tratamiento laparoscópico del QHH promedió los US 2.107. Creemos que la técnica laparoscópica, aplicada con criterio selectivo, es una alternativa útil para el tratamiento de pacientes con hidatidosis hepática, pues sus resultados son comparables a los existentes con cirugía abierta.Background: Laparoscopic surgery is emerging as a useful alternative for the treatment of liver hydatid cysts. Aim: To report technical data, management protocols, costs and results of laparoscopic management of liver hydatid cysts. Material and Methods: Prospective analysis of 31 patients aged 5 to 73 years (17 females, with 40 cysts, operated between 2006 and 2009. All patients received albendazol for 15 days prior to surgery and for 2 months afterwards. Surgical technique consisted in the evacuation of parasite membrane, partial excision of prominent pericystic membrane and suture of biliary communications. Results: Sixty nine percent of cysts were uni-vesicular, 74% were unique and 68% were located in the right lobe. Surgical time was 80 min. Two patients were converted to open surgery and 24% had postoperative complications. Mean hospital stay was six days. Patients were followed for 28 months and in 4% the cyst relapsed. No patient died. The mean cost of laparoscopic treatment was US$ 2.107. Conclusions: Laparoscopic technique is a useful surgical alternative for the treatment of liver hydatid cysts.

Scientific Electronic Library Online (English)

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

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.

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)

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

International Nuclear Information System (INIS)

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 ofcephalographical 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. (author)

Giant testicular tumor- a case presentation  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Background. Testicular cancer is the most common cancer in men 15 to 35 years old. Histological subtypes are seminoma, non-seminoma and mixed tumours (partly seminoma and partly non-seminoma). Seminomas are more sensitive to radiation therapy and are easier to cure than non-seminomas. The surgical treatment is either orchiectomy, either orchiectomy plus lymph node dissection of the involved ganglia.

Automated sonographic evaluation of testicular perfusion  

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Correlation between histological typing of epidermoid carcinoma and radiosensitivity of the uterine cervix  

International Nuclear Information System (INIS)

The so-called epidermoid type of carcinoma of the uterine cervix is classified under two different categories: real squamous type (Sqm) and transitional type (Tr). The former type (Sqm) is more sensitive to radiation therapy than the latter (Tr). In both Sqm and Tr, the poor maturation type is radiosensitive rather than the well mature type. In most cases, there is no significant difference in the radiosensitivity of the well matured Tr type and that of normal vaginal squamous endocervical columnar epithelium or stromal cells.

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 findingse 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.)

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

Directory of Open Access Journals (Sweden)

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

Peritubular myoid cells have a role in postnatal testicular growth  

Science.gov (United States)

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

Tumor testicular bilateral "quemado" ("burn out") / Burn out bilateral testicular tumor  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Es difícil diferenciar entre tumor de células germinales retroperitoneal primario y enfermedad metastásica de un tumor gonadal indetectado o que ha regresado espontáneamente. Presentamos un caso clínico de "burn out" o tumor quemado, es decir un tumor retroperitoneal seminomatoso, metastásico con im [...] portantes alteraciones testiculares bilaterales tanto ecográficas como anatomopatológicas, pero sin evidenciar tumor. 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.

Expression of gastrin-releasing peptide receptor in epidermoid carcinoma of the anal canal.  

Science.gov (United States)

Gastrin-releasing peptide is a neuroendocrine homolog of bombesin that demonstrated important growth-stimulatory effects in various types of cancer. High levels of expression of gastrin-releasing peptide receptors (GRPR) has been found in different malignancies, and the studies exploring the therapeutic use of GRPR antagonists have shown promising results. Our aim was to determine the GRPR expression in epidermoid carcinoma of the anal canal and discuss its potential clinical applications. We performed immunohistochemical analysis for GRPR on formalin-fixed and paraffin-embedded tumor samples obtained from 35 patients with anal cancer. As a control group, we analyzed 24 samples of nonmalignant anal tissues (hemorrhoidectomy specimens). GRPR expression was evaluated using a semiquantitative approach according to the intensity and distribution of staining. All analyzed tissues, except 1 control sample, showed positive GRPR immunoexpression. GRPR was strongly expressed in 54% of cancer specimens as compared with only 12% of the control specimens (P<0.003). In tumors, the receptor showed a diffuse and homogenous pattern of distribution within the specimens. In contrast, control specimens showed a focal pattern of staining restricted to the basal half of the epithelium. In conclusion, we demonstrated that GRPR is highly expressed in epidermoid carcinoma of the anal canal, suggesting this receptor might have a role in anal carcinogenesis. Our results provide a basis for exploiting GRPR as a target for diagnostic and therapeutic purposes in the anal cancer. PMID:23958544

Testicular sperm retrieval at the time of bilateral radical orchiectomy  

Directory of Open Access Journals (Sweden)

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

Mechanisms of testicular torsion and potential protective agents.  

Science.gov (United States)

Testicular torsion is a urological emergency most commonly seen in adolescence, involving a decrease in blood flow in the testis resulting from torsion of the spermatic cord that can result in gonad injury or even loss if not treated in time. Testicular ischaemia-reperfusion injury represents the principle pathophysiology of testicular torsion, with ischaemia caused by twisting of the spermatic cord, and reperfusion on its subsequent release. Many cellular and molecular mechanisms are involved in ischaemia-reperfusion injury following testicular torsion. Studies have investigated the use of pharmacological agents as supportive therapy to surgical repair in order to prevent the adverse effects of testicular torsion. Numerous substances have been proposed as important in the prevention of post-ischaemia-reperfusion testicular injury. A range of chemicals and drugs has been successfully tested in animal models for the purpose of mitigating the dangerous effects of ischaemia-reperfusion in testis torsion. PMID:24934447

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.

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 microlithiasis as a familial risk factor for testicular germ cell tumour.  

Science.gov (United States)

Testicular microlithiasis (TM) is characterised by small intratesticular calcifications, which can be visualised by ultrasound. Men with testicular germ cell tumour (TGCT) have a higher frequency of TM than men without TGCT. To clarify the association between TGCT and TM and to investigate the relationship between TGCT susceptibility and TM, we recruited TGCT patients with and without family history of TGCT, unaffected male relatives and healthy male controls from the UK. Testicular ultrasound data were analysed from 328 men. Testicular microlithiasis was more frequent in TGCT cases than controls (36.7 vs 17.8%, age adjusted P<0.0001) and in unaffected male relatives than controls (34.5 vs 17.8%, age adjusted P=0.02). Testicular germ cell tumour case and matched relative pairs showed greater concordance for TM than would be expected by chance (P=0.05). We show that TM is present at a higher frequency in relatives of TGCT cases than expected by chance indicating that TM is a familial risk factor for TGCT. Although the familiality of TM could be due to shared exposures, it is likely that there exists a genetic susceptibility to TM that also predisposes to TGCT. We suggest that TM is an alternative manifestation of a TGCT susceptibility allele. PMID:17971766

Proteomic analysis of testicular ischemia-reperfusion injury in rats.  

Science.gov (United States)

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

Laparoscopic surgery was performed to puncture-aspiration, partial cystectomy and omentoplasty of a cyst in 5th and 6th hepatic zone of 15cm diameter. It was obtained 250cc from cystic cavity, evaluated by light microscopy and confirmed the presence of rostellar hooks of Echinococcus sp. Later was made a total cystectomy of a 3cm diameter extra hepatic cyst located in large omentum. Patient went out at the hospital 48 hours after without complications. This work is the first report of a type III hydatid cyst by E. vogeli treated by laparascopy in Latin American.

[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

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

Evaluation of biomarkers for testicular toxicity  

Digital Repository Infrastructure Vision for European Research (DRIVER)

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

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.)

Testicular Cancer Survivorship: Research Strategies and Recommendations  

Digital Repository Infrastructure Vision for European Research (DRIVER)

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

Directory of Open Access Journals (Sweden)

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

Seasonal testicular function in male rhesus monkeys.  

Science.gov (United States)

Some studies report seasonal patterns of testicular function in male rhesus monkeys even when they are housed away from females, while others suggest that exposure to sexually active females is essential for male seasonality. We conducted the present experiment (1) to test claims that seasonal testicular activation occurs in the absence of females and (2) to determine whether regular exposure to and copulation with females enhances, or is without effect upon, seasonal increases in testicular function. We studied two groups of male monkeys housed in a colony room containing no females. Males in the Female Exposure group (n = 7) were paired twice weekly with estradiol-implanted females and copulated vigorously. Males in the second group (n = 7) were placed in the same test chamber (at least 16 h after it had been scrubbed with disinfectant) but were never exposed to females. Serum testosterone levels and testis volume were monitored for both groups. Each group displayed a seasonal pattern of testosterone and of testis volume comparable in timing and magnitude to seasonal increases previously reported in group-housed males, but the two groups did not differ from each other. Our findings confirm that seasonal changes in testosterone and testis size occur in the absence of sexual interaction and demonstrate that moderate levels of sexual activity do not enhance this response.

Testicular Histomorphometric Evaluation of Zebu Bull Breeds  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english The objective of this study was to evaluate the quantitative histology and testicular biometrics in zebu bulls of different breeds. Testicular fragments of Nelore (n=10), Polled Nelore (n=6), Gir (n=5), Guzerat (n=5) and Tabapuã bulls (n=5) were used. The fragments were perfusion-fixed in Karnovsky [...] solution, embedded in glycol methacrylate and stained with toluidine blue-1% sodium borate. The Nelore animals had a higher tubular volumetric proportion (85.2%) and greater height of the seminiferous epithelium (73.2 µm) than the Gir, Guzerat and Tabapuã breeds. The Nelore animals also had a higher volumetric proportion of Leydig cells (5.2%) than the Guzerat and Tabapuã breeds. There was no significant difference for any of these parameters between the Nelore and Polled Nelore breeds. The gonadosomatic index, seminiferous tubule diameter, cross-sectional area of the seminiferous tubule and tubule length (total length and length per gram of testicular parenchyma) did not vary among the breeds studied. The morphometric parameters evaluated suggested that the genetic selection applied to the Nelore and Polled Nelore breeds improved the efficiency of spermatogenesis in these breeders.

Testicular self-examination and testicular cancer: a cost-utility analysis.  

Science.gov (United States)

The United States Preventive Services Task Force (USPSTF) has recommended against testicular self-examinations (TSE) or clinical examination for testicular cancer screening. However, in this recommendation there was no consideration of the significant fiscal cost of treating advanced disease versus evaluation of benign disease. In this study, a cost-utility validation for TSE was performed. The cost of treatment for an advanced-stage testicular tumor (both seminomatous and nonseminomatous) was compared to the cost of six other scenarios involving the clinical assessment of a testicular mass felt during self-examination (four benign and two early-stage malignant). Medicare reimbursements were used as an estimate for a national cost standard. The total treatment cost for an advanced-stage seminoma ($48,877) or nonseminoma ($51,592) equaled the cost of 313-330 benign office visits ($156); 180-190 office visits with scrotal ultrasound ($272); 79-83 office visits with serial scrotal ultrasounds and labs ($621); 6-7 office visits resulting in radical inguinal orchiectomy for benign pathology ($7,686) or 2-3 office visits resulting in treatment and surveillance of an early-stage testicular cancer ($17,283: seminoma, $26,190: nonseminoma). A large number of clinical evaluations based on the TSE for benign disease can be made compared to the cost of one missed advanced-stage tumor. An average of 2.4 to 1 cost benefit ratio was demonstrated for early detected testicular cancer versus advanced-stage disease. PMID:25103095

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

International Nuclear Information System (INIS)

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

Quiste hidatídico retro-peritoneal: Una enfermedad frecuente en una ubicación inusual Retroperitoneal hydatid cyst: A common disease in a rare location  

Directory of Open Access Journals (Sweden)

Full Text Available La hidatidosis sigue siendo un problema prevalente en áreas endémicas. Presentamos el caso de un quiste hidatídico primario ubicado en el espacio retro-peritoneal. Mujer de 54 años, procedente de área rural del sur de Chile, hospitalizada por cuadro de coxalgia derecha y aumento de volumen glúteo, con tres meses de evolución. Se realizó el diagnóstico de hidatidosis complicada por medio de exámenes de imágenes, tests serológicos y anatomía patológica. No se demostraron quistes hidatídicos en otras ubicaciones. Se realizó un drenaje percutáneo del quiste infectado y se administraron antihelmínticos durante 12 semanas y actualmente permanece en seguimiento cercano con buena respuesta al tratamiento. El quiste hidatídico debe ser considerado en el diagnóstico diferencial de masas quísticas retro-peritoneales, especialmente en áreas endémicas.Echinococcal disease remains a major problem within some endemic areas. We report a case of a single primary echinococcal cyst located in the retroperitoneal space. A 54-year-old woman, born in a rural area of southern Chile, was admitted with a 3-month history of right hip pain and painful swelling of the gluteal region. Hidatid disease was confirmed with serologic test, radiological examinations and histo-pathology. There were no cysts in any other location. A percutaneous drainage was performed and antihelminthics were administered for 12 weeks and is now being closely followed up, with good response to therapy. Especially in the endemic areas hydatid cyst should be considered when evaluating retroperitoneal cystic masses.

Mitochondrial Pathway of ?-Tocopheryl Succinate-Induced Apoptosis in Human Epidermoid Carcinoma A431 Cells.  

Science.gov (United States)

Vitamin E derivatives are known to act as agents exhibiting cytotoxity against tumor cells. The effect of vitamin E succinate on human epidermoid carcinoma cell line A431 was investigated in this study using live imaging, immunocytochemistry, and transmission electron microscopy. ?-Tocopheryl succinate-induced apoptotic cell death in A431 cells was shown to be both dose- and time-dependent. The hyperproduction of reactive oxygen species, changes in size, shape and ultrastructural characteristics of mitochondria followed by the release of cytochromecfrom mitochondria to cytosol were observed. These results suggest that ?-tocopheryl succinate induces apoptosis that occurs via the mitochondrial pathway. Mitochondria are shown to be crucial targets in ?-tocopheryl succinate-induced caspase-dependent cell death in human carcinoma A431 cells. PMID:23150807

Epidermoid carcinoma arising in parotid adenolymphomatous lesion with microdeposit of amyloid substance.  

Science.gov (United States)

A case of an epidermoid carcinoma which arose in a cystic adenolymphoma-like lesion of the parotid gland is presented. Histologically, in the major part, the tumor tissue showed a papillary cystadenoma lymphomatosum-like pattern with the stroma consisting of mainly plasma cells and lymphocytes, but the epithelial element was mostly multilayered, showing a keratinous differentiation. In some areas, sebaceous-like cells and oxyphilic cells were found in the epithelial component. In the surrounding fibrous tissue, the invasive growth of the epithelial cells could be observed. Microdeposit of amyloid substance was found in the lymphoid stromal tissue and also in the intercellular space of the epithelial element. A mass of epithelioid cells and cholesterol crystal clefts were observed in the granulomatous tissue which proliferated around the tumor tissues. About 4 months after surgical excision, a recurrent tumor, which was well differentiated squamous cell carcinoma, appeared on the same site as the primary tumor. PMID:6837308

Trigeminal neuralgia secondary to epidermoid cyst at the cerebellopontine angle: case report and brief overview.  

Science.gov (United States)

Trigeminal neuralgia (TN) is a paroxysmal shock-like pain restricted to the innervations of the areas of one or more trigeminal branches, often set off by light stimuli in a trigger zone. Pain attacks occur spontaneously, and can also be triggered by a nonpainful sensory stimulus to the skin, intraoral mucosa surrounding the teeth, or tongue. The pathogenesis of TN is uncertain and typically is idiopathic, but it may be due to a structural lesion. Various proposed causes include traumatic compression of the trigeminal nerve by neoplastic or vascular anomalies, infectious agents such as human herpes simplex virus, and intracranial tumors or demyelinating conditions such as multiple sclerosis. Here we report a case of a young patient diagnosed with trigeminal neuralgia secondary to epidermoid cyst at the cerebellopontine angle. PMID:19184299

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)

A nationwide epidemiological study of testicular torsion in Korea.  

Science.gov (United States)

Testicular torsion is a surgical emergency in the field of urology. Knowledge of the epidemiology and pathophysiology is significant to an urologist. However, the epidemiology of testicular torsion in Korea has not been studied. We performed a nationwide epidemiological study to improve knowledge of the epidemiology of testicular torsion. From 2006-2011, the Korean Urologic Association began the patient registry service. The annual number of patients with testicular torsion from 2006 to 2011 were 225, 250, 271, 277, 345, and 210, respectively. The overall incidence of testicular torsion in males was 1.1 per 100,000; However, the incidence in men less than 25 yr old was 2.9 per 100,000. Adolescents showed the highest incidence. Total testicular salvage rate was 75.7% in this survey. There was no geographic difference of testicular salvage rate. Minimizing the possibility of orchiectomy for testicular torsion is important to improve public awareness to expedite presentation and provider education to improve diagnosis and surgery.
