Testicular epidermoid cyst; Quiste epidermoide testicular  

Energy Technology Data Exchange (ETDEWEB)

The testicular epidermoid cyst is an uncommon benign tumor that represents 1% to 2% of resected testicular masses. The observation of the characteristic ultrasonographic features of these lesions facilitates their diagnosis and may make it possible to perform enucleation, obviating the need for orchidectomy. We present two cases in which the testicular epidermoid cysts were diagnosed preoperatively and their presence confirmed after conservative surgery. We review the literature concerning imaging studies and the management of these lesions. (Author) 9 refs.

Quiste epidermoide intradiploico infratentorial gigante/ Giant intradiploic infratentorial epidermoid cyst  

Scientific Electronic Library Online (English)

Full Text Available Abstract in spanish Los quistes epidermoides son lesiones congénitas benignas, de lento crecimiento, que representan el 1% de todos los tumores intracraneales. En un 25% tienen una localización intradiploica y excepcionalmente infratentorial. Presentamos un caso clínico poco frecuente de un quiste epidermoide intradiploico gigante infratentorial. El paciente consultó por una diplopia y un síndrome cerebeloso. La tomografía computarizada y la resonancia magnética mostraron una lesión (more) 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 (more) 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.

Testicular microlithiasis and epidermoid cysts: a common pathway?  

Science.gov (United States)

We present the case of a boy with antenatally diagnosed bilateral testicular microlithiasis. Following annual surveillance the child developed metachronous bilateral epidermoid cysts. These were subsequently excised with testicular sparing surgery. Currently, there are only three cases of bilateral epidermoid cysts in the paediatric population, and none have been associated with testicular microlithiasis. This reignites the discussion regarding the histogenesis of epidermoid cysts and how its pathophysiology might relate to testicular microlithiasis. PMID:22763712

Testicular epidermoid cyst in Klinefelter's syndrome.  

UK PubMed Central (United Kingdom)

A 38-year-old Japanese man was referred to our outpatient clinic for treatment of infertility. Semen analysis showed azoospermia. Chromosome analysis revealed a 47XXY karyotype, and non-mosaic Klinefelter's syndrome (KFS) was diagnosed. Upon physical examination, the patient's right testicular volume was 30 mL and the left testicular volume was 3 mL. Laboratory tests showed normal levels of lactate dehydrogenase, alpha-fetoprotein, and human chorionic gonadotropin beta-subunit. The plasma luteinizing hormone and follicle-stimulating hormone levels were increased to 15.7 mIU/mL and 45.9 mIU/mL, respectively. The plasma testosterone was decreased to 0.25 ng/mL. Magnetic resonance imaging showed a right testicular mass of low-signal intensity on the T1-weighted image and of high-signal intensity on the T2-weighted image. Therefore, the final diagnosis was KFS with a right testicular tumor. Thus, a right high orchiectomy was performed. Histological examination revealed an epidermoid cyst of the right testis. Epidermoid cysts in cases of KFS are rare. To our knowledge, only seven cases, including ours, have been reported in the literature.

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 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 testicular (quiste dermoide) en su variante pseudopilomatrixoma. Estudio de extensión y marcadores tumorales negativos. El paciente se encuentra libre de enfermedad tras 6 m (more) eses 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 t (more) hree 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.

Quistes dermoides y epidermoides intracraneales  

Directory of Open Access Journals (Sweden)

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

El conocimiento de las lesiones quísticas testiculares en la infancia permite un adecuado manejo de las mismas y un tratamiento más conservador. Abstract in english The present article reports a case 11 month- old infant with a right intratesticular cyst. We analyze the etiology, differential diagnosis and management off all cystic lesions of the pediatric testis. Patient age at presentation, examination features, tumor markers and sonographic appearance may assist in making a presumptive and occasionally definitive diagnosis preoperatively. The differential diagnosis include intratesticular simple cyst, epidermoid cyst, tunica albug (more) inea 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.

Tumores testiculares en la infancia/ Testicular Tumours in Infancy and children  

Scientific Electronic Library Online (English)

Full Text Available Abstract in spanish Introducción: los tumores testiculares prepuberales son distintos a los que se presentan en la edad adulta. Tradicionalmente han sido considerados malignos, pero realmente los tumores testiculares benignos son más frecuentes en esta edad. Material y métodos: revisamos nuestra experiencia en el tratamiento de los tumores testiculares en niños (more) nuestro centro 15 tumores testiculares en edad pediátrica. Se revisa la actitud terapéutica empleada con énfasis en la posibilidad de preservación testicular en pacientes seleccionados y se evalúan los resultados. Resultados: la forma de presentación clínica en el 80% de los casos fue aumento del tamaño testicular con masa palpable. Se realizaron 4 orquiectomías radicales (27%) y 11 tumorectomías (73%). Todas las lesiones benignas en la anatomía patológica definitiva fueron tratadas con tumorectomía: cuatro quistes epidermoides, un hemangioma, un lipoma, un hamartoma fibroso, un tumor de la granulosa juvenil y una fusión espleno-gonadal. También fueron tratados con éxito de forma conservadora dos casos de teratoma. Los casos tratados de manera radical fueron un caso de tumor de saco vitelino (estadio I), dos tumores germinales mixtos y un gonadoblastoma. Conclusiones: los tumores testiculares en la edad prepuberal benignos predominan sobre los malignos. Ante una masa testicular palpable con marcadores tumorales negativos se puede plantear un tratamiento conservador mediante tumorectomía. No obstante, la lesión debe ser completamente extirpada para evitar recurrencias. Abstract in english Introduction: prepubertal testicular tumours are different from those that appear during adulthood. Traditionally, they were considered to be malignant, however benign testicular tumours are actually more frequent at this age. Materials and methods: we analysed our experience in the treatment of testicular tumours in children (more) at our centre. We examined the therapeutic approach employed, underlining the possibility of testicular conservation in selected patients and we have analysed the results. Results: the clinical presentation in 80% of the cases was an increase in testicle size with palpable mass. We performed 4 radical orchiectomies (27%) and 11 tumourectomies (73%). All the benign lesions in the final pathological anatomy were treated with tumourectomy: four epidermoid cysts, one hemangioma, one lipoma, one fibrous hamartoma, one juvenile granulosa tumour and one splenogonadal fusion. We also successfully and conservatively treated two cases of teratoma. The cases that received radical treatment were a yolk sac tumour (Stage I), two mixed germ cell tumours and one gonadoblastoma. Conclusions: there are more cases of benign testicular tumours than malignant tumours during puberty. In the event of a palpable testicular mass with negative tumour markers, conservative treatment by means of a tumourectomy may be considered. However, the lesion must be removed completely to prevent recurrence.

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.

Epidermoid cyst of the testis: a case report  

Energy Technology Data Exchange (ETDEWEB)

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

Giant earlobe epidermoid cyst.  

UK PubMed Central (United Kingdom)

Epidermoid cysts represent the most common cutaneous cysts. They are usually small and benign; however, sometimes they can grow to giant epidermoid cists, and occasionally malignancies develop. Giant epidermoid cysts at the earlobe have never been described but in other locations. We describe a case of a giant epidermoid cyst at the earlobe, a location where such a large cyst has never been reported before. The mass was completely resected and the wound of the pedunculated base was sutured with four stitches of nylon 5/0. Histopathology confirmed the presumptive diagnosis of an epidermoid cyst. Six months after the resection, the patient did not have any relapse of the epidermoid cyst. The earlobe is a potential location for giant epidermoid cysts. Although the clinical diagnosis could be enough, due to the possibility of malignancy and to ensure appropriate diagnosis, we consider that all cysts should be sent to the anatomic pathology laboratory for histological evaluation.

Intradiploic epidermoid cysts  

International Nuclear Information System (INIS)

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

Neuroradiological aspects of intracranial epidermoids  

International Nuclear Information System (INIS)

Intracranial epidermoids are primarily extracerebral congenital cysts. Intra- and extradural types are differentiated: intradural lesions originate in the intracranial CSF spaces, and extradural lesions in the bony skull. Epidermoids increase in size passively as the results of an increase in the cyst volume and not because of active growth. Clinically epidermoids behave like benign, slow-growing cerebral tumours. Differential diagnosis includes other cysts and cystic tumours. Neuroradiologically epidermoids present as polycystic lesions showing extensive growth in the extracerebral CSF spaces and secondary invagination of the brain. On CT and MR, despite the high cholesterol content, epidermoids show the characteristics of liquor and not those of fat. It can be shown that he typical CT and MR appearance of an epidermoid is due to the different proportions of CSF in the cyst content, which results from diffusion of dehiscence of te cyst capsule. The present study was based on analysis of 6 cases selected from a total of 29 patients with CNS epidermoids. (orig.)

Primary intradiploic pterional epidermoid cyst.  

UK PubMed Central (United Kingdom)

A 72-year-old woman who developed a left temporal protrusion was referred to our center. An MRI showed a heterogeneous mass in the left temple with T2 signal hyperintensity within the intradiploic space of the greater wing of the sphenoid bone, measuring 2.4 x 2.1 cm. The patient underwent a surgical removal of the mass through the pterional approach. Pathology showed an epidermoid cyst. Intradiploic epidermoid cysts of the skull are rare benign tumors of the skull. These lesions grow slowly and are composed of epidermoid cells debris rich in cholesterol. The prophylactic removal of these tumors with the goal of preventing recurrences is recommended.

Prepubertal testicular tumours and efficacy of testicular preserving surgery.  

UK PubMed Central (United Kingdom)

STUDY TYPE: Therapy (case series). LEVEL OF EVIDENCE: 4. What's known on the subject? and What does the study add? Testicular tumours in childhood are very rare. Historically, most of these tumours have been considered malignant, but more recent studies indicate that benign lesions, particularly teratoma, are much more frequent than previously thought. Testicular tumours in this age group have traditionally been treated with inguinal radical orchiectomy, but more conservative management has been proposed in view of the higher frequency of benign tumours. In children, most testicular tumours are benign, especially before puberty. A testis-sparing procedure should be performed in children with a palpable testicular mass and negative tumour markers. OBJECTIVE: To report our experience of testicular tumours in children aged?13 years, including our experience with testis-sparing surgery. PATIENTS AND METHODS: A retrospective study was performed of 15 patients with testicular tumours aged?13 years who presented at our centre between 1984 and 2008. The use of testis-preserving surgery according to indication was investigated and outcomes were recorded. RESULTS: The clinical presentation was increased testicular size with a palpable mass in 80% of the cases. All 15 patients underwent surgery. The tumour was benign in 12 (80%) patients and malignant in three (20%) patients. Organ-preserving surgery was planned and achieved in 11 patients (73%). Pathology of the tumourectomy specimens disclosed benign tumours in all cases: four epidermoid cysts, two teratomas, one juvenile granulosa cell tumour, one haemangioma, one lipoma, one fibrous hamartoma and one splenogonadal fusion. In four patients who underwent radical orchiectomy, pathology identified one yolk sac tumour (stage I), two mixed germ cell tumours and one gonadoblastoma. CONCLUSIONS: In children, most testicular tumours are benign, especially before puberty. A testis-sparing procedure should be performed in children with a palpable testicular mass and negative tumour markers. The lesion, however, should be thoroughly excised to avoid recurrences.

[Testicular microlithiasis  

UK PubMed Central (United Kingdom)

Testicular microlithiasis is an uncommon condition in which calcified concretions fill the lamina of seminiferous tubules. It has a specific appearance on sonography with diffuse intra testicular echogenic foci without acoustic shadows. Testicular microlithiasis can be associated with various entities and frequently with primary testicular neoplasm. The authors report a new case of testicular microlithiasis diagnosed by sonography in a 14-year-old boy with epididymo-orchitis. Based on a review and discussion of the literature, the authors emphasize the importance of regular and protracted ultrasound follow-up and monitoring of serum tumour markers to allow early detection of primary testicular neoplasm.

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.

Quiste suprarrenal primario Primary adrenal cyst  

Directory of Open Access Journals (Sweden)

Full Text Available Los quistes suprarrenales son las lesiones quísticas más frecuentes de la glándula suprarrenal, a pesar de que constituyen una rara entidad. 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 radiológicos 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.Adrenal cyst is the commonest type of benign lesions of adrenal gland, althought is a very rare entity. Tipically, they are presented with abdominal pain or palpable mass, but nowdays they are detected most frecuently an imaging studies like incidentaloma. Adrenal Cyst have a broad differential diagnoses, 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.

[Intracranial epidermoid and dermoid cysts  

UK PubMed Central (United Kingdom)

INTRODUCTION: Dermoid and epidermoid cysts are dysembryogenic tumors representing 1% of all intracranial tumors. They are characterized by slow growth, localization to the middle in relation to the basal cisterns and their benign course. OBJECTIVES: To analyze the clinical and radiological characteristics, and the results of surgical treatment of intracranial dermoid and epidermoid cysts. PATIENTS AND METHODS: We reviewed 18 cases of epidermoid and 3 dermoid intracranial cysts which had been diagnosed and treated during a period of 18 years. All patients were diagnosed by computerized tomography (CT) and the last 15 cases by magnetic resonance (MR). RESULTS: The commonest site was the temporal lobe with 7 cases, followed by the suprasellar region with 4 cases. All patients had peculiar imaging characteristics both on CT (hypodense and with no contrast silhouetted) and on MR (hypointensity in T1 and in T2). They were completely resected in 16 cases. There were 3 episodes of aseptic meningitis and 2 deaths. CONCLUSIONS: Dermoid and epidermoid cysts are characterized by long term clinical symptoms. The commonest site is supratentorial in the midline or in the temporosylvian region. The diagnostic investigation of choice is MR. Treatment is surgical, preferably complete resection. However, after sub-total resection there is a prolonged period of remission.

[Testicular tumours in infancy and children].  

UK PubMed Central (United Kingdom)

INTRODUCTION: prepubertal testicular tumours are different from those that appear during adulthood. Traditionally, they were considered to be malignant, however benign testicular tumours are actually more frequent at this age. MATERIALS AND METHODS: we analysed our experience in the treatment of testicular tumours in children ? 13, with the intention of evaluating the use of partial orchiectomy. From 1984 to 2008, we diagnosed and treated 15 testicular tumours in children at our centre. We examined the therapeutic approach employed, underlining the possibility of testicular conservation in selected patients and we have analysed the results. RESULTS: the clinical presentation in 80% of the cases was an increase in testicle size with palpable mass. We performed 4 radical orchiectomies (27%) and 11 tumourectomies (73%). All the benign lesions in the final pathological anatomy were treated with tumourectomy: four epidermoid cysts, one hemangioma, one lipoma, one fibrous hamartoma, one juvenile granulosa tumour and one splenogonadal fusion. We also successfully and conservatively treated two cases of teratoma. The cases that received radical treatment were a yolk sac tumour (Stage I), two mixed germ cell tumours and one gonadoblastoma. CONCLUSIONS: there are more cases of benign testicular tumours than malignant tumours during puberty. In the event of a palpable testicular mass with negative tumour markers, conservative treatment by means of a tumourectomy may be considered. However, the lesion must be removed completely to prevent recurrence.

Prepubertal testicular tumors: Our 10 years experience  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Testicular tumors in the pediatric population are distinct from those of the adults. In contrast to the prevalence data reported in tumor registries, several studies have shown that a majority of the prepubertal testis tumors are benign. We retrospectively analyzed a series of prepubertal testicular tumors. Materials and Methods: A retrospective review of all testicular tumors at our institution was done from Jan 1999 to Dec 2008. Data relating to presentation, evaluation, and management were collected. Results: A total of 22 children with prepubertal testicular tumors were identified. The mean age at presentation was 4.6 years. Mature teratoma, epidermoid cysts, immature teratoma, and yolk sac tumor accounted for 49.94%, 13.62%, 9.08%, and 18.16%, respectively. All surgeries were successful with respect to cancer control and testicular preservation. Conclusions: Benign tumors formed the majority (72.64%) of the tumors that were encountered, with yolk sac tumors (18.16%) being a minority. Testicular preserving surgery appears to be a feasible option for benign tumors and is safe and efficacious in long-term follow-up.

Epidermoid cyst mimicking an intrinsic brainstem tumor.  

UK PubMed Central (United Kingdom)

OBJECTIVE: To describe an atypical clinical and radiological presentation of a brainstem epidermoid cyst in a child and to provide a review of the medical literature on brainstem epidermoid cysts in children. MATERIAL AND METHOD: Review of medical records and operative notes of an unusual case of a patient with a brainstem epidermoid cyst. MEDLINE literature search using the terms brainstem, epidermoid cyst and children. RESULTS: Gross total resection of the cyst was achieved. The patient had an uneventful recovery. CONCLUSION: Epidermoid cysts are rare tumors of the brain and children. The management of these tumors can be quite challenging. A good clinical and neuroradiological evaluation pre-operatively is fundamental for a successful surgical treatment. Surgical resection should be as radical as possible without putting the patient's neurological status into risk.

Testicular trauma.  

UK PubMed Central (United Kingdom)

The incidence of rupture in cases of blunt testicular trauma is 48 per cent. Conservative management in cases of contusion or rupture of the testis has resulted in a 45 per cent failure rate and a 45 per cent orchiectomy rate when delayed exploration was required. Early exploration of patients with testicular trauma has resulted in only a 9 per cent orchiectomy rate, a shortened hospital stay, a greatly reduced period of disability and a faster return to normal activity.

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

[Deutsch] Intrakranielle Epidermoide sind primaer extrazerebrale kongenitale Zysten. Es sind intra- von extraduralen Formen zu unterscheiden. Intradurale Epidermoide entstehen in den intrakraniellen Liquorraeumen, extradurale im Schaedelknochen. Epidermoide vergroessern sich nicht aktiv durch autonomes Wachstum, sondern passiv durch Zunahme des Zysteninhalts. Klinisch verhalten sie sich wie gutartige, langsam wachsende Hirntumoren. Differential-diagnostisch sind sie gegenueber anderen Zysten und zystischen Tumoren abzugrenzen. Neuroradiologisch sind Epidermoide durch ihre polyzyklische Konfiguration und ihre extensive Ausdehnung in den extrazerebralen Liquorraeumen mit sekundaerer Invagination in das Gehirn gekennzeichnet. Im MR und im CT stellen sich Epidermoidzysten trotz des hohen Gehaltes an Cholesterin nicht fett-, sondern liquoraequivalent dar. Es kann nachgewiesen werden, dass die Ursache fuer die Abbildungseigenschaften der Epidermoide in einer unterschiedlichen transmuralen Beimengung von Liquor cerebrospinalis zum Zysteninhalt liegt. Die Studie basiert auf der Analyse von 6 Faellen, die aus einem Gesamtkollektiv von 29 Patienten mit Epidermoiden des Zentralnervensystems ausgewaehlt wurden. (orig.)

Experience with testis sparing surgery for testicular teratoma.  

UK PubMed Central (United Kingdom)

PURPOSE: Testicular teratoma is a rare neoplasm affecting the pediatric population and has classically been reported to be the second most common testis tumor in children behind yolk sac tumors. Testicular teratomas are benign and partial orchiectomy may be considered. We describe our single institution experience with testicular teratoma and definitive treatment with testis preserving surgery. MATERIALS AND METHODS: We reviewed the pathology records at our institution for all testicular and paratesticular tumors diagnosed between 1976 and November 2002 in males younger than 18 years. We specifically examined the prepubertal incidence of teratoma, including epidermoid cysts, and our experience with testis preserving surgery. Preoperative and postoperative ultrasonography images were used to calculate the atrophy index following surgery. Patients were contacted for long-term followup. RESULTS: Of 77 primary testicular and paratesticular tumors 38 were diagnosed in prepubertal boys (age younger than 13 years) including 11 mature teratomas and 5 epidermoid cysts. Mean patient age at treatment was 34.4 months (range 4 months to 10 years). All boys presented with a painless scrotal mass, cystic foci within an intratesticular mass on ultrasound and a normal alpha-fetoprotein level. Of the 16 boys with benign teratomas 13 (81%) were treated with a testis sparing procedure. At a mean 7-year followup no patient has presented with recurrent tumor in the ipsilateral or contralateral testicle. Postoperative physical examination and scrotal ultrasound were obtained in 9 patients at a median followup of 10.2 months, and there was no evidence of testicular atrophy or persistent discomfort. CONCLUSIONS: Unlike previously published series based on tumor registries, benign teratoma was the most common pediatric testicular tumor treated at our institution. Our single institution experience with testis preservation and long-term followup confirms the role and safety of this technique. Testis sparing surgery remains our technique of choice for testicular teratoma.

Full Text Available Objetivo. Describir y analizar la asociación entre quistes aracnoideos e higroma subdural. Esta es considerada una complicación excepcional, con sólo 24 casos reportados en la literatura, siendo de cinco casos la serie publicada más numerosa. Método. Se realizó el análisis retrospectivo de las historias clínicas de 5 pacientes portadores de quiste aracnoideo, en los que la forma de presentación consistió en higroma subdural e hipertensión endocraneana. Resultados. El rango de edad fue entre 3 y 15 años (promedio: 7 años). La relación M/F fue 3/2. En 3 casos los síntomas se presentaron después de un traumatismo encefalocraneal leve y en los 2 restantes fue espontáneo. Todos se manifestaron con síntomas de hipertensión endocraneana y edema de papila bilateral, en 2 de ellos se constató paresia del VI par izquierdo. A todos se les realizó TAC y en 2 casos IRM. En los 5 pacientes se constató un higroma subdural con efecto de masa y quiste aracnoideo de fosa media. Se realizó tratamiento quirúrgico de urgencia en los 5 casos. Todos los pacientes evolucionaron favorablemente con desaparición del higroma subdural. Actualmente se encuentran asintomáticos con un examen neurológico y fondo de ojo normal. Conclusión. Si bien el higroma subdural con hipertensión endocraneana es una complicación poco usual, debe ser tenida en cuenta como una de las formas de presentación clínica de los quistes aracnoideos, la cual requiere inmediata resolución quirúrgica.Objetive: To analyze and describe the association between arachnoid cysts and subdural hygroma.

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

Posttraumatic intradiploic epidermoid cyst of frontal bone.  

UK PubMed Central (United Kingdom)

Intracranial epidermoid cysts constitute about 1% of all intracranial tumors. They are usually congenital in origin and are thought to derive from ectodermal cell inclusions occurring during closure of the neural tube. Twenty-five percent of these are found in the skull as intradiploic epidermoid cysts. These intradiploic cysts are usually congenital, slow growing, and can grow to large size without causing symptoms. We present a case of intradiploic epidermoid cyst of frontal bone developed due to childhood trauma. The cyst expanded and eroded the walls of the frontal sinus causing proptosis, diplopia, and restricted eye movements with frontal headache. The bicoronal flap approach was used for complete removal of the cyst. Complete removal of the cyst wall is necessary to avoid recurrence.

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.

Paraplegia due to Spinal Epidermoid Cyst Rupture at Asthma Attack.  

UK PubMed Central (United Kingdom)

Spinal epidermoid cyst is less than 1% of the entire spinal cord tumor and a rare tumor. It is a slowly proliferating benign tumor and can be a result of either congenital or acquired factors. In particular, reports of acute paraplegia due to spinal epidermoid cyst rupture are very rare. Since authors experienced paraplegia resulting from congenital spinal epidermoid cyst rupture during an asthma attack, it is reported with a review of literature.

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.

Endoscopic Assisted Resection of Prepontine Epidermoid Cysts.  

UK PubMed Central (United Kingdom)

Objective/Background To describe an innovative endoscopic technique to treat prepontine epidermoid cysts. These cysts are typically resected in a microsurgical fashion and can be associated with significant risks and complications. This report is the first description of an endoscopic-assisted removal of an epidermoid cyst without the use of the operative microscope and evaluates the operative findings, technique, and postoperative course.Study Design Retrospective review at tertiary referral center.Methods Two patients, one with rapidly progressive headache and ataxia, and another with trigeminal neuralgia were found to have mixed-intensity cystic lesions of the prepontine region consistent with an epidermoid cyst. A detailed description of the preoperative preparation, surgical approach, intraoperative technique, pre- and post-operative imaging findings and monitoring outcomes are emphasized.Results Both patients underwent resection of the epidermoid cyst using an endoscope-assisted technique. The procedures were 3 and 4 hours in duration with an estimated blood loss of 50 cc in both operations. No intraoperative complications occurred. The patients were discharged from the hospital on postoperative days 2 and 3, respectively. Postoperative imaging revealed no edema of the cerebellum and complete resolution of the cyst. Neurological examination revealed improvement of preoperative symptoms with complete resolution of headache and ataxia of case 1, with resolution of trigeminal neuralgia in case 2. Case 2 did develop an ipsilateral cranial nerve (CN) VI paresis postoperatively that resolved over a 3-week period. The patient from case 1 remains symptom free after 24-months with magnetic resonance imaging (MRI) consistent with gross-total resection of the epidermoid cyst. Case 2 has continued resolution of trigeminal neuralgia and CN VI palsy with 12-month follow-up MRI consistent with gross total resection.Conclusions The use of the endoscope as the sole means to access the posterior fossa to treat prepontine cystic lesions affords the surgeon excellent visualization with minimal cerebellar retraction and can be done in a safe and effective manner with little to no morbidity.

Quiste óseo aneurismático Aneurysmal bone cyst  

Directory of Open Access Journals (Sweden)

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

Isodense epidermoid cyst in the pineal region  

International Nuclear Information System (INIS)

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

Estudio inmunohistoquímico del carcinoma epidermoide de labio/ Epidermoid carcinoma of the lip: An immunohistochemical study  

Scientific Electronic Library Online (English)

Full Text Available Abstract in spanish Objetivos: Determinar la sobreexpresión de las proteínas c-erb-B2, p53, bcl-2, Ki67 y CD44varV6 y establecer su valor pronóstico en el carcinoma epidermoide de labio. Diseño del estudio: Estudio inmunohistoquímico de las proteínas p53, c-erb-B2, bcl-2, ki67 y CD44varV6 en 79 carcinomas epidermoides de labio diagnosticados y tratados a lo largo de un periodo de 20 años. Los datos obtenidos fueron sometidos a análisis estadístico uni y multivariante. Resultados: La (more) inmunotinción fue positiva en el 75% de los casos para la proteína c-erb-B2, en el 70,6% para la proteína p 53, en el 3,8% para la proteína bcl-2 y en el 89,9% para la molécula de adhesión cd44varV6. La expresión proteica de ki67 osciló entre un mínimo de 0% y un máximo de 6,29%. Los factores inmunohistoquímicos analizados no presentaron valor pronóstico en el carcinoma epidermoide de labio, y solamente los pacientes afectados por este tipo de tumores que expresaban la molécula de adhesión CD44varV6 se asociaron de forma significativa con una mayor supervivencia mediante el análisis de Kaplan-Meier. Conclusiones: Las técnicas inmunohistoquímicas analizadas para el estudio anatomopatológico del carcinoma epidermoide de labio no deberían realizarse rutinariamente, dado su mayor coste y su menor utilidad en la práctica clínica diaria. Abstract in english Objectives: To determine the expression of the c-erb-B2, p53, bcl-2, Ki67 and CD44varV6 proteins, and to establish their prognostic value in epidermoid carcinoma of the lip. Study design: Immunohistochemical study of the c-erb-B2, p53, bcl-2, Ki67 and CD44varV6 proteins in 79 epidermoid carcinomas of the lip, diagnosed and treated over a period of 20 years. The data obtained were subjected to uni- and multi-variate statistical analyses. Results: Immunostaining was positiv (more) e in 75% of cases for c-erb-B2 protein, in 70.6% for p53 protein, in 3.8% for bcl-2 protein and in 89.9% for adhesion molecule CD44varV6. Ki67 protein expression varied between a minimum of 0% and a maximum of 6.29%. Most immunohistochemical factors analyzed presented no prognostic value for epidermoid carcinoma of the lip. Only those patients affected by this type of tumor that expressed the adhesion molecule CD44varV6 were significantly associated with a greater survival calculated by means of Kaplan-Meier analysis. Conclusions: The immunohistochemical techniques analyzed for the anatomicopathological study of epidermoid carcinoma of the lip should not routinely be used due to their high cost and low utility in daily clinical practice.

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

Directory of Open Access Journals (Sweden)

Full Text Available 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. Material 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.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.

Early epidermoid carcinoma. A case presentation Carcinoma epidermoide primitivo. Presentación de un caso  

Directory of Open Access Journals (Sweden)

Full Text Available The early epidermoid carcinoma is considered the strangest breast tumor with an incidence that only represents from 0,04 to 0,075 % out of all malignant tumors of the breast. It is a variety of the metaplastic carcinoma constituted by pavement keratinizing cells with an inconstant presence of fusocellular sarcomatoid elements, that reach great volume and frequently present as cystic tumours that may be confused with a breast abscess. This is the case of a 41 year-old white female from Cienfuegos municipality, Cuba, who presented to the provincial Mastology consultation because of a two month follow up of a 5 cm tumor in the right outer upper quadrant of her breast. Surgical removal of the tumor was performed and the result of the biopsy revealed a little differentiated epidermoid carcinoma. At present the patient has no metastasis and receives treatment at the outpatient. Its unusual presentation has led this case to be published.

[Epidermoid cysts of the spermatic cord  

UK PubMed Central (United Kingdom)

We report two cases of epidermoid cyst of the spermatic cord in infants 14 months and 2 1/2 years old, respectively. The initial diagnosis in one patient was funicular hydrocele and paratesticular mass no transilluminable in the other case. The treatment was the local excision of tumor and the diagnostic was histological in both patients. Postoperative course was excellent in both, the first after fistullization and surgical treatment. Must be explored the transillumination of the mass which would have led us to think other of the diagnoses different from that of the cord hydrocele before the operation, since it would have given negative. During the operation, must be assured that the cystic anomaly is limited to spermatic cord, to evite fistulization in the postoperative course.

Resultados del tratamiento quirúrgico del quiste broncógeno Results of the surgical treatment of the bronchogenic cyst  

Directory of Open Access Journals (Sweden)

Full Text Available El quiste broncógeno es una malformación congénita poco frecuente, que generalmente requiere tratamiento quirúrgico. Con el objetivo de evaluar los resultados obtenidos en pacientes intervenidos quirúrgicamente por quiste broncógeno, se realizó un estudio descriptivo de 9 pacientes consecutivos operados entre julio de 1995 y julio de 2004. Se evaluó edad, sexo, manifestaciones clínicas y técnicas quirúrgicas empleadas. Los resultados se determinaron en función de las complicaciones y la mortalidad. En 5 casos la lesión era de localización intraparenquimatosa ?en uno de ellos se ubicaba en la cisura interlobar izquierda? y en 4 se localizaba en el mediastino medio. Se practicaron 9 operaciones primarias y 3 reoperaciones. En un caso se dejó un fragmento de la pared del quiste que no fue posible resecar. Se realizó lobectomía inferior a 3 de los pacientes con quistes intraparenquimatosos (dos derechas y una izquierda). A los otros dos se extirpó el quiste, que en uno había sustituido prácticamente al lóbulo superior izquierdo hipoplásico. En 5 pacientes el acceso se realizó mediante videotoracoscopia (una conversión) y en 4 mediante toracotomía convencional. Se produjo apertura bronquial durante la extirpación del quiste mediante videotoracoscopia en un paciente. Hubo 3 reoperaciones (en 2 pacientes): por sangrado (1) y por atelectasia con infección pulmonar intratable y hematoma abscedado (1). Otras complicaciones fueron la sepsis de la herida (2) y el derrame pleural (1). No se ha documentado ninguna recidiva del quiste ni fallecidos. El tratamiento quirúrgico de los quistes broncógenos no está exento de complicaciones, pero produce buenos resultados a largo plazo

Carcinoma en quiste tirogloso/ Carcinoma in thyroglosal duct cyst  

Scientific Electronic Library Online (English)

Full Text Available Abstract in spanish El carcinoma diferenciado de tiroides en quiste tirogloso (CaQT) es una rara entidad. En diferentes series de pacientes operados por quistes tiroglosos su incidencia fue del 0.7 al 1.07%. Luego de la extirpación del quiste por el procedimiento de Sistrunk, no hay consenso sobre la indicación de tiroidectomía total, radioablación y/o terapéutica supresiva con levotiroxina. El objetivo del Departamento de tiroides de SAEM, fue evaluar: formas de presentación, evoluci? (more) ?n clínica, métodos diagnósticos de utilidad y tratamiento para consensuar futuras conductas. Material y Métodos: Estudio multicéntrico, retrospectivo en 22 pacientes entre 10 a 69 años, 15 mujeres y 7 varones. Resultados: El tamaño de los quistes osciló entre 1 y 8 cm (Mediana= 3.0 cm, ? ± DS= 3.7 ± 2.2 cm). La mitad de los pacientes presentó crecimiento del quiste en los 6 meses previos a la cirugía. La punción resultó sospechosa en 2/5 quistes y positiva en uno. La ecografía tiroidea evidenció nódulos en 4/13 casos (30%). Se realizó tiroidectomía en 17/22 pacientes (total: 15 y subtotal: 2). La histología del CaQT demostró carcinoma papilar en 21 y carcinoma folicular en uno. Hubo coexistencia de cáncer intratiroideo en el 23.5% de los casos, ninguno multicéntrico. Dos pacientes presentaron metástasis ganglionares y otro tuvo compromiso muscular (ninguno de ellos coexistió con cáncer intratiroideo). Se radioablacionó a 13 pacientes.

Conclusiones: 1) Realizar ecografía de cuello y punción ecoguiada a todo paciente con quiste tirogloso. 2) En caso de CaQT combinar simultáneamente tiroidectomía total y procedimiento de Sistrunk. 3) Evaluar radioablación complementaria y tratamiento supresivo con levotiroxina en cada caso. 4) Efectuar el seguimiento tal como en los carcinomas ortotópicos. Abstract in english Differentiated thyroid carcinoma (DTC) in thyroglosal duct cyst (TGDC) is rare, ranging from 0.7 to 1.07% in different series. After the surgery of choice (Sistrunk procedure) the other alternative treatments such as thyroidectomy (Tx), radioiodine and L-T4 therapy are controversial. OBJECTIVE: to evaluate several and controversial aspects in the largest series of DTC in TGDC reported in the literature. Subjects and methods: retrospective multicentric study: n= 22, aged 1 (more) 0-69 yrs. (15 females and 7 men) who underwent the Sistrunk procedure for TGDC. Results: none of the TGDC was less than 1 cm (median 3.0 cm, ?±SD= 3.7 ± 2.2cm). In half of them there was an increased cystic size in the last 6 months before surgery. Cyst FNA was suspicious in 2/5 and positive in one, whereas the histological diagnosis of the operated TGCD was papillary cancer in 21 and 1 follicular carcinoma. Thyroid ultrasound (US) (n=13) showed nodules in 30% of the cases. Tx was performed in 17/22 (total: 15, subtotal: 2). Thyroid DTC coexisted in 4/17 (23.5%), and was unilateral in all of them. Lymph node metastases were present in 2 adults and muscle involvement was found in the 10-year old girl. None of these 3 patients had overt thyroid lesions. 131-I therapy was performed in 10 patients. In 9 out of 11 subjects Tg remained undetectable during follow-up (1-14yrs.). Persistent high Tg was present in one case without thyroid DTC. Conclusions: 1) Ultrasonography and FNAB should be performed to every patient with thyroglossal duct cyst 2) In case of TGDC, total Tx and Sistrunk's procedure should be simultaneously combined 3) 131-I therapy and L-T4 suppressive treatment should be evaluated in every case 4) Follow-up as in the DTC.

Carcinoma en quiste tirogloso Carcinoma in thyroglosal duct cyst  

Directory of Open Access Journals (Sweden)

Full Text Available El carcinoma diferenciado de tiroides en quiste tirogloso (CaQT) es una rara entidad. En diferentes series de pacientes operados por quistes tiroglosos su incidencia fue del 0.7 al 1.07%. Luego de la extirpación del quiste por el procedimiento de Sistrunk, no hay consenso sobre la indicación de tiroidectomía total, radioablación y/o terapéutica supresiva con levotiroxina. El objetivo del Departamento de tiroides de SAEM, fue evaluar: formas de presentación, evolución clínica, métodos diagnósticos de utilidad y tratamiento para consensuar futuras conductas. Material y Métodos: Estudio multicéntrico, retrospectivo en 22 pacientes entre 10 a 69 años, 15 mujeres y 7 varones. Resultados: El tamaño de los quistes osciló entre 1 y 8 cm (Mediana= 3.0 cm, ? ± DS= 3.7 ± 2.2 cm). La mitad de los pacientes presentó crecimiento del quiste en los 6 meses previos a la cirugía. La punción resultó sospechosa en 2/5 quistes y positiva en uno. La ecografía tiroidea evidenció nódulos en 4/13 casos (30%). Se realizó tiroidectomía en 17/22 pacientes (total: 15 y subtotal: 2).

Epidermoid cyst of the posterior fossa: a case report/ Cisto epidermoide da fossa posterior: relato de caso  

Scientific Electronic Library Online (English)

Full Text Available Abstract in portuguese Os cistos epidermoides do sistema nervoso central (SNC) são condições incomuns, estando localizados mais frequentemente no ângulo pontocerebelar e ao redor da ponte. Eles são revestidos por epitélio escamoso queratinizado e lamelas de queratina, tornando seu conteúdo branco-perolado e pastoso. Os cistos epidermoides são, na maioria das vezes, originados de malformações, possivelmente associados ao entremeio de elementos superficiais do ectoderma do SNC durante o (more) fechamento da placa neural, ou formação das vesículas cerebrais secundárias. Os autores descrevem um caso de cisto epidermoide da fossa posterior determinando hidrocefalia e revisam critérios morfológicos e diagnósticos dessa lesão. Abstract in english Epidermoid cysts of the central nervous system are uncommon conditions, which are frequently located in the cerebellopontine angle and around the pons. They are covered with keratinized squamous epithelium and keratin lamella, which give its contents a soft, white-pearly appearance. Epidermoid cysts are mostly originated from malformations, presumably associated with surface elements of the nervous system ectoderm during the closure of the neural groove or formation of se (more) condary cerebral vesicles. The authors describe a case of epidermoid cyst in the posterior fossa causing hydrocephalus and review morphologic and diagnostic criteria of this lesion.

Quistes epididimarios en la infancia/ Epididymal cysts in childhood  

Scientific Electronic Library Online (English)

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

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.

Full Text Available Nipun Kalsotra, Manjeet Singh, Siddhartha Sharma, Dara SinghDepartment of Orthopaedics, Government Medical College Jammu, Jammu and Kashmir State, IndiaAbstract: Epidermoid cysts of the finger phalanx are rare pseudotumors. They are benign lesions with a satisfactory outcome after excision. It is important to differentiate this benign lesion, which can be easily treated by curettage, from other benign and malignant lesions of the bone with a similar clinical presentation, and which may require amputation. We describe a case of an epidermoid cyst in the distal phalanx of the ring finger. It was treated successfully and the patient had excellent functional results at one-year follow-up.Keywords: finger phalanx, epidermoid cyst, lytic bone lesion

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.

Quiste ovárico fetal: diagnóstico prenatal y manejo quirúrgico postnatal exitoso  

Directory of Open Access Journals (Sweden)

Full Text Available Los quistes ováricos son el tumor abdominal mas frecuente en las recién nacidas. Presentan complicadones agudas y a largo plazo. La más frecuente es la torsión anexial que presenta dificultades diagnósticas en la etapa neonatal. El diagnóstico prenatal es fundamental para el manejo oportuno de las pacientes. Existen diferentes alternativas terapéuticas donde la cirugía mínimamente invasiva y conservadora juega un importante rol. Presentamos el caso de una recién nacida macrosómica con diagnóstico prenatal de quiste ovárico no complicado que sufrió torsión durante los primeros días de vida y se resolvió exitosamente en forma quirúrgica conservadora gracias a un manejo multidisciplinario.Ovarian cysts are the most common abdominal tumor in female newborns. They could develop acute or long term complications. The most frequent complication is adnexal torsion, which presents with diagnostic difficulties in the neonatal period. Prenatal diagnosis is essential for the prompt management of patients. There are different treatment options where conservative and minimally invasive surgery plays an important role. We report a female newborn with prenatal diagnosis of macrosomia and uncomplicated ovarian cyst, which suffered adnexal torsion during the first days of life and was successfully resolved with a conservative surgical management by a multidisciplinary staff.

[Epidermoid cysts and implants. Anatomo-pathologic findings  

UK PubMed Central (United Kingdom)

A case is reported that is exceptional in more than one respect. The mandibular region was the site of development of three cysts: a radiculo-dental cyst, a coronodental cyst in appearance but which could have been an epidermoid cyst and a typical epidermoid cyst. Lingual nerve lesions are a rare, major complication of implantations. Dismounting of a stable implant is a very rare occurrence. Histopathology showed a bone integration process in contact with the major part of implant, an interposed fibrous band existing in certain sectors only.

FDG Uptake in Splenic Epidermoid Cyst With Hemorrhage.  

UK PubMed Central (United Kingdom)

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

Spinal epidermoid cyst with sudden onset of paraplegia  

Directory of Open Access Journals (Sweden)

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

Iatrogenic intraspinal epidermoid tumor: Myelo-CT and MRI diagnosis  

Energy Technology Data Exchange (ETDEWEB)

An 11-year-old boy, treated for acute lymphatic leukemia at the age of 2 with intrathecal injections of Methotrexate, presented with a two year history of pain and signs of lumbo-sacral lesion. MRI, myelography and myelo-CT demonstrated an intradural L4-L5 epidermoid tumor which was removed. Iatrogenic implantation of epithelial cells at the age of two with lumbar punctures is most likely. Decline in incidence of lumbar iatrogenic epidermoid cysts, now an exceedingly rare event, is probably related to improved needles for lumbar punctures. (orig.).

Abordaje endoscópico de los quistes gliales pineales sintomaticos  

Directory of Open Access Journals (Sweden)

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

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

Con el objetivo de evaluar los resultados obtenidos en pacientes intervenidos quirúrgicamente por quiste broncógeno, se realizó un estudio descriptivo de 9 pacientes consecutivos operados entre julio de 1995 y julio de 2004. Se evaluó edad, sexo, manifestaciones clínicas y técnicas quirúrgicas empleadas. Los resultados se determinaron en función (more) de las complicaciones y la mortalidad. En 5 casos la lesión era de localización intraparenquimatosa ?en uno de ellos se ubicaba en la cisura interlobar izquierda? y en 4 se localizaba en el mediastino medio. Se practicaron 9 operaciones primarias y 3 reoperaciones. En un caso se dejó un fragmento de la pared del quiste que no fue posible resecar. Se realizó lobectomía inferior a 3 de los pacientes con quistes intraparenquimatosos (dos derechas y una izquierda). A los otros dos se extirpó el quiste, que en uno había sustituido prácticamente al lóbulo superior izquierdo hipoplásico. En 5 pacientes el acceso se realizó mediante videotoracoscopia (una conversión) y en 4 mediante toracotomía convencional. Se produjo apertura bronquial durante la extirpación del quiste mediante videotoracoscopia en un paciente. Hubo 3 reoperaciones (en 2 pacientes): por sangrado (1) y por atelectasia con infección pulmonar intratable y hematoma abscedado (1). Otras complicaciones fueron la sepsis de la herida (2) y el derrame pleural (1). No se ha documentado ninguna recidiva del quiste ni fallecidos. El tratamiento quirúrgico de los quistes broncógenos no está exento de complicaciones, pero produce buenos resultados a largo plazo

Endoscopic-Assisted Resection of Intracranial Epidermoid Tumors.  

UK PubMed Central (United Kingdom)

OBJECTIVE: Intracranial epidermoid tumors are epithelially derived lesions that may present particular challenges to neurosurgeons, often encasing critical neurovascular structures and extending into multiple subarachnoid cisterns. We aimed to evaluate our recent experience with endoscopic assistance to craniotomy with microsurgical resection of these lesions. METHODS: A retrospective review of patients undergoing endoscopic-assisted craniotomy for resection of an epidermoid tumor at the Keck School of Medicine of USC between 2009-2012 was conducted. In all patients, the surgical approach and tumor resection were first performed microscopically. This was followed by use of an angled endoscope to facilitate further inspection and additional resection of tumor using a two-surgeon technique. RESULTS: Twelve patients undergoing 13 consecutive endoscopic-assisted craniotomies were included in the analysis. The mean patient age was 45 years. The mean maximal tumor diameter was 4.0 cm (range 2.4-5.8 cm). Surgery was for recurrent epidermoid in 6 of 13 cases (46%). Epidermoid tumor location included the cerebellopontine angle (9 patients, 75%), fourth ventricle (2 patients, 17%), and third ventricle (1 patient, 8%). Surgical approaches included retro-sigmoid craniotomy (8 patients), sub-occipital craniotomy (1 patient), sub-occipital craniotomy with supra-cerebellar approach (1 patient), extradural temporopolar approach (1 patient), and subtemporal approach (1 patient). In 11 of 13 cases (85%), additional tumor was identified upon inspection with an angled endoscope, facilitating additional tumor resection in each case. Gross or deliberate near total resection was achieved in 7 of 13 cases (54%). Four patients (31%) had improvement of cranial nerve function. Post-operative neurological deficits included transient abducens and oculomotor nerve paresis in 1 patient each. CONCLUSION: The endoscope is a safe and effective adjunct to the microscope in facilitating additional inspection and further resection of epidermoid tumors. Endoscopic-assisted surgery is particularly useful for identifying and removing additional tumor located around surgical corners.

Testicular germ cell tumors.  

UK PubMed Central (United Kingdom)

Testicular cancer is the most frequent solid tumor in young male adults and a disease with elusive pathogenesis. Germ cell tumors represent 95% of all testicular cancers. There was an increasing incidence of testicular germ cell tumors during the second half of the 20th century. Despite their increased incidence, mortality is lower than 10% and the cure rate has reached 95%. Epidemiology of the disease shows remarkable geographic and racial variation. Known risk factors and the increased incidence during the last 50 years have led to the development of the two prevalent theories for the pathogenesis of the disease, Henderson theory and Rajpertde Meyts and Skakkebaek theory. Appropriate diagnosis and staging of the disease are crucial for successful management. Testicular ultrasound, CT scans, histological examination and serum tumor markers should be utilized in order to stratify the patient correctly. Treatment strategy is chosen according to the patient stage and prognostic group stratification. "Fine tuning" is needed in order to find the balance between treatment, cure and toxicity. Despite progress in therapeutic management, cure rates for poor risk patients do not exceed 50%. These patients should be encouraged to participate in clinical trials. Long-term toxicity of testicular germ cell tumors' treatment is also another issue that should be kept in mind during follow-up of these patients. This disease became the model of "curable" cancer and gave hope for cure of metastatic malignant diseases in general, as only 400 patients die from this disease in USA annually. More progress will be made only through well-designed clinical trials.

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.

[Paraneoplastic limbic encephalitis and epidermoid carcinoma of the pyriform  

UK PubMed Central (United Kingdom)

Paraneoplastic limbic encephalitis is a syndrome characterised by behaviour changes, short-term memory loss and seizures. We report on a case of a 62-year-old man, ex-smoker who was admitted to the Intensive Care Unit with seizures, and who had previously experienced behaviour changes. Tests revealed nothing notable, except for the CSF examination which revealed elevated protein and MRI findings indicating temporal lobe abnormalities. Once other diagnoses had been ruled out, neoplasm screening was initiated. Conventional imaging failed to identify the tumour. Antineuronal anti-Hu antibodies were negative. Finally, fluorodeoxyglucose (FDG) whole body -PET imaging was carried out revealing a pathologically increased glucose metabolism at the pharynx-larynx level. The biopsy showed an epidermoid carcinoma of the pyriform sinus. To the best of our knowledge, this is the first reported case of an epidermoid carcinoma of the pyriform sinus associated with paraneoplastic limbic encephalitis.

Craniopharyngioma and epidermoid tumour in same child: a rare association.  

UK PubMed Central (United Kingdom)

Simultaneous occurrence of histologically different primary brain tumours is rare, and its preoperative diagnosis is still challenging. The explanations for the simultaneous occurrence of different primary intracranial tumours in the absence of phacomatoses or prior radiation exposure are at present hypothetical, and these tumours could be simply coincidental. Herein, we report a case of a boy presenting with features of raised intracranial pressure and right-sided sensorineural hearing loss. Brain MRI revealed two different neoplastic pathologies at different sites: an intrasellar and suprasellar craniopharyngioma and a right cerebello-pontine angle epidermoid. To the best of our knowledge, this is the first report in literature of a craniopharyngioma coexisting with an epidermoid, in the same individual.

Testicular cancer in cryptorchids.  

UK PubMed Central (United Kingdom)

One-hundred thirty-seven patients with a history or clinical evidence of cryptorchidism and testicular germinal tumor were treated at our hospital from 1934 to 1976. Cryptorchidism was corrected ipsilaterally or contralaterally in 93 patients with intrascrotal testis cancer when they were from 2 to 42 years old, either spontaneously (24 patients), by orchiopexy (58 patients), or by hormonal therapy (11 patients). Forty-four cryptorchid patients (uncorrected cases) had either ipsilateral inguinal (24 patients), or abdominal (14 patients), or contralateral intrascrotal tumors (six patients). Tumor histologic types on orchiectomy were pure seminoma in 56 patients, embryonal carcinoma in 41, teratocarcinoma in 37, and pure choriocarcinoma in 3. The five-year survival rates were similar in the corrected (61%) and uncorrected (63%) cases, and they were higher in patients with pure seminoma (79%) than in patients with germinal carcinomas (50%). The majority (64 of 80) of five-year survivors received regional lymphatic irradiation in 41 patients with pure seminoma and/or systemic chemotherapy in 23 patients with other germinomas. Since the testicular tumors that developed despite correction of the cryptorchid state were predominantly (72%) germinal carcinomas, unilateral cryptorchidism, which usually is associated with testicular atrophy, should be treated by orchiectomy instead of orchiopexy to prevent ipsilateral carcinogenesis. Cryptorchid patients with testicles that descended late should be observed periodically, especially after the 20-year latent period, for early detection of cancer.

Quiste de Baker en el curso de la artritis reumatoidea  

Directory of Open Access Journals (Sweden)

Full Text Available Se presentó un caso con diagnóstico de artritis reumatoidea seropositiva, de un año de evolución, que llevó tratamiento con aines y metotrexate, a pesar de lo cual, mantuvo actividad inflamatoria articular en el nivel de carpos y rodillas, que desarrolló un aumento de volumen de la región posterior de ambas piernas, con dolor espontáneo y signo de Homans positivo. Se valoró la posibilidad inicial de una tromboflebitis de la región poplítea y se llegó a la conclusión que se trataba de un quiste de Baker.A case with diagnosis of seropostive rheumatoid arthritis and a year of evolution was presented. The patients was treated with non-steroidal anti-inflammatories and methotrexate. In spite of this, the inflammatory articular activity was maintained at the level of the carpus and knees and there was a volume increase in the posterior region of both legs, with spontaneous pain and positive Homan´s sign. At first, it was evaluated the possibility of a thrombophlebitis of the popliteal region, but, finally, it was considered as a Baker´s cyst.

Giant testicular seminoma.  

UK PubMed Central (United Kingdom)

Primary testicular germ cell tumors typically present with painless testis enlargement and have a propensity to spread to the retroperitoneal lymphatics. Delays in seeking treatment are unfortunately common and may lead to metastatic spread. Pure seminomas are the most commonly seen on histology and are not associated with elevations in serum alpha-fetoprotein. Mild elevations in alpha-fetoprotein in the setting of a pure seminoma may be due to unrecognized nonseminomatous elements and rarely other benign etiologies. We present the case of a 42-year-old man with a large 31 cm stage I pure seminoma and mildly elevated alpha-fetoprotein level at presentation.

Primary testicular lymphoma.  

UK PubMed Central (United Kingdom)

Primary testicular lymphoma (PTL) is a rare disease accounting for 1% of non-Hodgkin's lymphoma. PTL occurs more frequently in older patients and is a potentially fatal disease. In the early stages (I and II), the treatment consists of orchidectomy followed by chemotherapy (CT) and prophylactic scrotal radiotherapy (RT) with/or without iliac and/or paraaortic lymph node RT. In the advanced stages (III and IV), CT is the treatment of choice whereas the place of scrotal RT is controverted. In both early and advanced disease intrathecal CT is warranted to prevent CNS relapse. New molecular approaches and/or more aggressive treatments are being explored.

Tumores y quistes del hígado: tratamiento quirúrgico resectivo  

Directory of Open Access Journals (Sweden)

Full Text Available Se aplicó tratamiento quirúrgico resectivo del hígado a 68 pacientes en los 3 hospitales clinicoquirúrgicos de Santiago de Cuba, durante 8 años (1987-1994). En 28 enfermos los tumores eran malignos, en 27 benignos y en el resto quistes solitarios, con predominio del hígado metastásico en los primeros y del hemangioma cavernoso en los segundos. El cáncer primitivo se diagnosticó en las etapas III y IV. Se practicaron 18 resecciones mayores, entre ellas 8 trisegmentectomías derechas, mientras que las restantes consistieron en resecciones menores y atípicas, sobre todo hepáticas regladas. Aparentemente las complicaciones peroperatorias y posoperatorias no tenían relación con la magnitud de la ablación. El absceso subfrénico fue el de mayor incidencia. La mortalidad no se relacionó con la técnica quirúrgica empleada, pero sí con la etapa clínica del tumor maligno y las complicaciones durante la operación y después de éstaLiver surgical resection treatment was applied to 68 patients in 3 clinical and surgical hospitals in Santiago de Cuba during 8 years (1987-1994). Tumours were malignant in 28 patients, benign in 27 and solitary cysts in the rest, with predominance of metastasic liver among the first and of cavernous hemangioma among the second ones. Primitive cancer was diagnosed in stages III and IV. 18 major resections were performed. 8 of them were right trisegmentectomies and the rest were minor and atypic resections, mainly ruled hepatic resections. Apparently, preoperative and postoperative complications were not connected with the magnitude of ablation. The subphrenic abscess had the highest incidence. Mortality was not related to the surgical technique used, but it was to the clinical stage of the malignant tumour and to the complications during and after the operation

QUISTES RETRO-AREOLARES EN ADOLESCENTES: ASPECTOS CLÍNICOS Y ULTRASONOGRAFICOS  

Directory of Open Access Journals (Sweden)

Full Text Available Los quistes retroareolares son frecuentes en niñas pre y postmenárquicas. Raramente se diagnostican en el varón. Corresponden a dilataciones quísticas de glándulas mamarias accesorias que se abren junto con una glándula sebácea en la areola, pueden ser únicos o múltiples, uni o bilaterales, palpables o hallazgos incidentales en ecografía. Los no complicados tienen morfología variable, paredes delgadas y contenido anecogénico, pudiendo observarse sedimento calcico en su lumen. Los complicados presentan paredes engrosadas, hipervascularizadas, con contenido ecogénico, avascular, tejidos adyacentes hiperecogénicos y aumento de la vascularización al Doppler color. Sin tratamiento, pueden transformarse en abscesos retroareolares. La complicación inflamatoria se trata con antiinflamatorios y/o antibióticos. No requieren biopsia diagnóstica ni punción evacuadora, puesto que se drenan espontáneamente a la areola. El conocimiento del cuadro clínico y su aspecto ul-trasonográfico permitirá orientar adecuadamente a los pacientes y sus familiasRetroareolar cysts are common in pre and postmenarchic girls. Boys are rarely diagnosed with this condition. They correspond to cystic dilatations of the accessory mammary glands that open along with a sebaceous gland at the areola and can be single or multiple, uni or bilateral, palpable or incidental findings on ultrasound. They have variable morphology, thin walls, anechogenic content, sometimes calcic sediment can be observed in their lumen. Infected cysts present enlarged, hypervascularized walls; their content is echogenic, avascular and the adjacent tissue is hyperechogenic, with increased vascularization at color Doppler. If not treated, may become retroareolar abscesses. Inflamatory complications are treated with anti-inflamatory drugs and/or antibiotics. No diagnostic biopsy or puncture aspiration is required, since they are spontaneously drained at the areola. In order to appropriately advise patients and families, it is necessary to have knowledge of both the medical and the ultrasonographic aspects of them and their complications

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.

En ocasiones estos tumores son difíciles de diferenciar de los quistes renales multiloculados u otras lesiones benignas como quistes hemorrágicos. Presentamos un caso de quiste renal complejo en el que la RNM mostró un patrón de quiste simple. El diagnóstico y manejo de estas lesiones debe ser muy cuidadoso y si persisten las imágenes sospechosas está justificada la exploración quirúrgica. Abstract in english Approximately 15% of cases of renal cell carcinoma present cystic configuration on radiologic and pathologic examination. These lesions are often difficult to differentiate from the multiloculated renal cyst or other benign cystic lesions such as hemorrhagic cyst and so on. We report a case of multilocular cyst of the right kidney complicated with clear cell type renal cell carcinoma in which MRI suggested benign cyst. The diagnosis of complicated benign cyst must be proposed very cautiously and the persistence of doubtful images justifies surgical exploration.

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

Directory of Open Access Journals (Sweden)

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

A giant testicular teratoma  

International Nuclear Information System (INIS)

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

Crossed testicular ectopia.  

UK PubMed Central (United Kingdom)

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 findings 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.

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

UK PubMed Central (United Kingdom)

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.

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.

Impacto de la dieta sobre la inducción de infección con quistes de Giardia lamblia en ratas Sprague-Dawley  

Directory of Open Access Journals (Sweden)

Full Text Available Objetivo. Evaluar el efecto de la desnutrición en la inducción de la giardiosis con diferentes concentraciones de quistes de Giardia lamblia utilizando como modelo animal ratas Sprague-Dawley. Material y métodos. Es un estudio experimental efectuado entre 1995 y 1999, en el Centro de Investigación en Alimentación y Desarrollo, de la ciudad de Hermosillo, estado de Sonora, México, y cuya muestra estuvo integrada por dos grupos de 6 a 8 unidades experimentales, las cuales recibieron dos tipos de dieta y cinco tratamientos con diferente concentración de inóculo de quistes de Giardia lamblia. Durante la fase experimental se monitoreó la excreción de quistes, ganancia de peso, consumo de alimento, análisis del contenido intestinal y daños macro y microscópicos en mucosa intestinal. El tratamiento estadístico de los datos consistió en análisis de varianza, y de residuales cuando fue necesario. Resultados. En los animales alimentados con una dieta que cubre sus requerimientos nutricionales (DN) se observó que es posible provocar la infección con 60 quistes, mientras que en los animales desnutridos (dieta DLN) la concentración que se requiere es de únicamente seis quistes para establecer daños a nivel de mucosa intestinal. Conclusiones. La ganancia de peso monitoreada durante los 10 días de ensayo no resultó ser un buen indicador de la infección por Giardia lamblia. El porcentaje de infección depende de la concentración de quistes inoculados y del estado de nutrición de los animales evaluados.

Anatomico-radiological study of intraosseous epidermoid cysts  

International Nuclear Information System (INIS)

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

Cryptorchidism and testicular cancer.  

UK PubMed Central (United Kingdom)

An analysis of 125 patients with a history or clinical evidence of cryptorchidism and testicular germinal tumor treated at our hospital from 1934 to 1975 is presented. Cryptorchidism was corrected ipsilaterally or contralaterally in 83 patients with intrascrotal testis cancer when they were from 4 to 42 years old, either spontaneously (21 patients), by orchiopexy (51 patients) or by hormonal therapy (11 patients). Forty-two cryptorchid patients (uncorrected cases) presented with either ipsilateral inguinal (24 patients), abdominal (14 patients) or contralateral intrascrotal tumors (4 patients). Tumor histologic types on orchiectomy were pure seminoma in 54 patients, embryonal carcinoma in 35, teratocarcinoma in 33 and pure choriocarcinoma in 3. The 5-year survival rates were 60 per cent for the corrected cases and 63 per cent for the uncorrected cases according to cryptorchid state, and they were 78 per cent in patients with pure seminoma and 48 per cent in patients with other germinomas according to histologic type. The majority (58 of 73) of 5-year survivors received regional lymphatic irradiation, in 39 patients with pure seminoma, and/or systemic chemotherapy, in 19 patients with germinal carcinomas, with or without regional lymphadenectomy.

CT and MR findings of presacral epidermoid cyst: a case report  

International Nuclear Information System (INIS)

Epidermoid cysts of the presacral space is a rare benign congenital lesion which is lined with keratinized squamous epithelium. We describe the computed tomography (CT) and magnetic resonance (MR) imaging findings in a case of presacral epidermoid cyst in a 35-year-old woman. The lesion appeared on CT as a well defined cystic mass with a thin wall. MR imaging showed heterogeneously low signal intensity on T1-weighted images and heterogeneously high signal intensity on T2-weighted images.

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.

Full Text Available El quiste dermoide representa menos del 0,01 % de todos los quistes de la cavidad bucal. Su ubicación más frecuente es en suelo de boca. Se presenta el caso de una paciente femenina de 19 años de edad que hacía aproximadamente 7 años había notado un aumento de volumen debajo de la lengua, el cual le crecía paulatinamente y ya se apreciaba por fuera de la cara. Además, le ocasionaba molestias al hablar y al masticar. Se realizaron estudios complementarios y bajo anestesia general nasotraqueal. Se procedió a su exéresis quirúrgica mediante un abordaje intrabucal, donde se obtuvieron excelentes resultados estéticos y funcionales. El diagnóstico histopatológico se correspondió con un quiste dermoide de suelo de boca. La paciente no ha tenido recurrencia de la lesión transcurridos tres años de la operación. El quiste dermoide de suelo de boca se presenta como una tumoración benigna de la línea media. La exéresis intrabucal demuestra beneficios estéticos y funcionales.The Dermoid cyst account for the 0.01 % of all cysts of buccal cavity. Its more frequent location is in the mouth floor. This is the case of a female patient aged 19 who approximately 7 years noted an increase of volume under tongue growing gradually and noting outside face and the discomfort at to speak and to chew. Complementary studies were conducted and under general anesthesia a surgical exeresis was carried out by intrabuccal approach achieving excellent esthetic and functional results. Histopathologic diagnosis matched with a dermoid cyst of mouth floor. Patient has not lesion recurrence after three years after operation. We conclude that the Dermoid cyst of mouth floor appear as benign tumor of middle line. The intrabuccal exeresis demonstrates esthetic and functional benefits.

¿SON ÚTILES LOS ANTICONCEPTIVOS ORALES EN EL TRATAMIENTO DE LOS QUISTES OVÁRICOS FUNCIONALES?  

Directory of Open Access Journals (Sweden)

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

Claves para el diagnóstico dermatopatológico de los quistes cutáneos. Dermatopathological clues for the diagnosis of skin cysts  

Directory of Open Access Journals (Sweden)

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

MANEJO LAPAROSCÓPICO DE QUISTES OVÁRICOS COMPLICADOS O PERSISTENTES DURANTE EL EMBARAZO  

Directory of Open Access Journals (Sweden)

Full Text Available Antecedentes: El incremento en el hallazgo de quistes anexiales durante el embarazo sería el mayor uso de técnicas de reproducción asistida con hiperestimulación ovárica controlada. La complicación más frecuente sigue siendo la torsión anexial. Objetivo: Revisar el manejo de quistes anexiales complicados o persistentes, durante el embarazo, con resolución laparoscópica. Método: Revisión retrospectiva de 9 pacientes consecutivas, ingresadas al Departamento de Obstetricia y Ginecología Clínica Las Condes. Resultados: La edad gestacional de ingreso fue entre 5+5 y 27 semanas. Cinco casos fueron producto de fertilización asistida y cuatro espontáneos. Ocho (85,6%) embarazadas, ingresaron por dolor abdominal agudo. Otro caso ingresó a cirugía electiva por quiste ovárico persistente. Los quistes tenían entre 6 y 13 cm. En 5 se realizó sólo destorsión ovárica, en 1 ooforectomía y en 1 quistectomía. Se realizó punción, destorsión y fijación a ligamento útero ovárico, bilateral, en la otra paciente. Se registró un caso de fiebre en el postoperatorio. El alta hospitalaria fue a las 48 horas en 6 (67%), a las 72 en 2 y a las 96 en 1. El estudio biópsico diferido en 3 pacientes demostró: 1 quiste seroso paratubario, 1 quiste luteínico parcialmente hemorrágico y 1 infarto anexial. Todos los embarazos evolucionaron normalmente. Conclusión: Nuestra experiencia confirma que en el embarazo la laparoscopía es una buena opción al requerir una cirugía por quiste anexial complicado o persistente.Background: Recent reviews show an increase in the finding of adnexal cysts during pregnancy. One reason could be the use of assisted reproductive techniques with controlled ovarian hyperstimulation. Objective: To review the experience in managing via laparoscopy complicated or persistent adnexal cysts during pregnancy. 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.

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. Abstract in english Background: Recent reviews show an increase in the finding of adnexal cysts during pregnancy. One reason could be the use of assisted reproductive techniques with controlled ovarian hyperstimulation. Objective: To review the experience in managing via laparoscopy complicated or persistent adnexal cysts during pregnancy. Method: Retrospective review of 9 consecutive patients, admitted at the Department of Obstetrics and Gynecology, Clínica Las Condes. Results: The gestati (more) onal 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.

[Epidermoid neoplasm of the fourth ventricle. Report of two cases].  

UK PubMed Central (United Kingdom)

BACKGROUND: epidermoid neoplasm (EN) accounts for 1 % of whole intracranial neoplasms. Usually, it is found at the cerebello-pontine angle and the location in the fourth ventricle (FV) is rare. The aim was to report two cases of EN of the FV. CLINICAL CASES: case 1: a female 22 year old presented with an intense headache with a history of 3 months. At the hospital entry, symptoms and signs of high intracranial pressure were found. Tomography images showed hydrocephalus with high pressure in the FV. She was treated with a shunt from ventricular to peritoneal cavity. After that an encapsulated neoplasm was drawn. It had a pearled aspect. The histology report showed an EN originating in the FV. Case 2: a female 44 year old with a history of five years of dizziness; three years before admission she presented intermittent diplopia and disophagia. At the hospital admission the patient presented paresis of the 6th and 7th cranial nerve. The tomography and the magnetic resonance studies showed a mass in the FV. The neoplasm was extirpated. CONCLUSIONS: the EN of the FV is an infrequent benign lesion. Magnetic resonance is the standard diagnostic study, but it could lead to confusion with neurocisticercosis. The extirpation and the treatment of the hydrocephalus are indicated.

[Medical treatment of epidermoid carcinoma of the anus  

UK PubMed Central (United Kingdom)

From January 1987 to May 1988 11 patients with epidermoid carcinoma of the anus were treated with Chemotherapy and Radiotherapy, six female and five males, between 46 and 90 years and a medium of 66. Five patients had recurrent disease to a previous treatment of surgery, radiotherapy or both. Chemotherapy treatment consisted of Mitomicine C 15 mg/m2 on day 1 and 5--FU 1 g/m2/d IV by 96 hours infusion. In the last six patients Mitomycin C was changed to Cisplatin to a dose of 80-100 mg/m2 on day 1. Radiotherapy to the pelvis was started on the first day of QT, with the exception of two patients with disseminated disease. The total response rate was 90.8% (6 CR and 4 PR). Those patients that did not receive previous treatment, had a complete response in 83.3% of the cases. The three patients that received Cisplatin as initial treatment have a complete response. All patients that received the treatment with curative intention and had an initial complete response are without evidence of disease after 33 to 47 months of follow up.

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

Directory of Open Access Journals (Sweden)

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

Congenital Epidermoid Cyst of the Oral Cavity: Prenatal Diagnosis by Sonography  

Science.gov (United States)

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

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

UK PubMed Central (United Kingdom)

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

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

Scientific Electronic Library Online (English)

Full Text Available 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 pueden 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 trat (more) amiento 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, called 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 sacrolumb (more) al 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.

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.

Laringocele como diagnóstico diferencial de quiste tiroideo Laryngocele as a differential diagnosis of a thyroid cyst  

Directory of Open Access Journals (Sweden)

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

[Calcinosis of the scrotum. Report of a case associated with epidermoid cysts  

UK PubMed Central (United Kingdom)

Clinical and histological features of a case of the so-called idiopathic calcinosis of the scrotum in a 22 year-old otherwise healthy man are presented. In a first biopsy we did not observe any evidence of squamous epithelial lining around calcified masses, but in a second one we observed some intact epidermoid cysts and granulomas of foreign-body type around keratinous material. These findings suggest that scrotal calcinosis is not idiopathic, but rather the end stage of dystrophic calcification of scrotal epidermoid cysts.

Cerebellopontine angle epidermoid showing a positive enhancement upon metrizamide CT cisternography  

Energy Technology Data Exchange (ETDEWEB)

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

Familial testicular cancer and urogenital developmental anomalies.  

UK PubMed Central (United Kingdom)

In a case-control study of testicular cancer, 6 of 269 cases (2.2%) reported a first-degree relative with testicular cancer, compared to 1 of 259 controls (0.4%). Fathers and brothers of testicular cancer cases had a six-fold elevated risk of developing a testicular malignancy compared to men in the general population. Cryptorchidism was reported in a first-degree relative in 1 (17%) of the familial cases versus 7 of 259 (2.7%) controls and 14 of 263 (5.3%) cases with a negative family history for testicular cancer. One half of the 6 familial cases reported a first-degree relative with a groin hernia (all surgically repaired before age 12), compared to 12.7% of 259 controls and 10.3% of 263 nonfamilial cases. Three familial clusters identified through the case-control study were selected for clinical evaluation. One of the 6 surviving males with testicular cancer in these 3 families had undergone orchiopexy and inguinal herniorrhaphy at age 6 years, and one had a hydrocele associated with his testicular tumor. Of the 12 living fathers and brothers of these 6 men, 3 reported childhood inguinal hernias, two with coexisting hydroceles. One additional hernia and two additional hydroceles were detected during urologic evaluation of these healthy relatives. The high prevalence of cryptorchidism, inguinal hernias, and hydroceles among men in these families suggests that an underlying alteration in urogenital embryogenesis may be associated with the familial predisposition to testicular neoplasia.

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

Directory of Open Access Journals (Sweden)

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

Testicular mass: do not forget filariasis.  

Science.gov (United States)

Parasite infestation of the testicular tunica and spermatic cord by filariae are rarely reported and may present with few clinical signs, depending upon the stage. Occasionally, it may mimic a testicular tumor. We present a case of a 29-year-old man who presented with left testicular swelling and discomfort for 4 months. Clinical examination and imaging suggested an intrascrotal cystic lesion with a normal left testis. However, the intraoperative findings revealed a tumor-like mass; hence, a left orchidectomy was performed. However, histopathology reported a diagnosis of a cystic testicular tunica and spermatic cord with parasite infection. Here, we review the literature of scrotal and testicular parasite disease and discuss the course of the appropriate management involved. PMID:23471824

Epidermoid cyst of the spleen: value of noninvasive imaging modalities in preoperative diagnosis  

Energy Technology Data Exchange (ETDEWEB)

Epidermoid cyst of the spleen is the rarest benign nonparasitic cyst of the spleen. We describe such a case and show how it may be evaluated noninvasively with a combination of imaging modalities. Additionally, by using these modalities in the clinical setting of a young woman with vague abdominal complaints, the diagnosis can be strongly suggested preoperatively.

[Epidermoid cyst of the 4th ventricle. Apropos of a case in a child and review of the literature  

UK PubMed Central (United Kingdom)

A 6 year-old child was admitted for a recurrent bacterial meningitis at Proteus Morganii. She was treated with antibiotics. The C.T. Scanner showed a midline low-density lesion, with a mild annular contrast uptake in the posterior fossa. M.R.I. showed the lesion and revealed a skin-bone-dura fistula. The surgical resection was complete. It was an epidermoid tumor. Intracranial epidermoid tumors constitute about 1% of brain tumors and are considered to be congenital. Epidermoid tumors of the 4th ventricle are exceedingly rare in childhood. The authors reviewed the literature and discuss the pathogeny, the radiographic diagnosis and the treatment of these tumors.

Association of an Epidermoid Tumour with Ipsilateral Aneurysms of Middle Cerebral Artery Bifurcation and Anterior Communicating Artery  

Directory of Open Access Journals (Sweden)

Full Text Available By this case report the authors are aimed to describe an unusual case of epidermoid tumour associated with ipsilateral two cerebral aneurysms. Radiological and clinical findings of a 45 year old male patient are described. Investigation of the patient revealed a right temporal lobe tumour and ipsilateral two aneurysms. The patient is treated with micro-neurosurgery successfully. Both the tumour and the right MCA aneurysm are interfereted in the same session. His pathological diagnose was epidermoid tumour. Togetherness of epidermoid tumours and cerebral aneurysms is a very rare entity. Further studies are needed to demonstrate the exact pathological and genetic mechanisms.

A histopathologic study of epidermoid cysts in Korea: comparison between ruptured and unruptured epidermal cyst.  

UK PubMed Central (United Kingdom)

BACKGROUND: An epidermoid cyst is a common epithelial-lined cyst. There have been many studies on epidermoid cysts, but few focused on ruptured epidermoid cyst and its histopathologic characteristics. OBJECTIVE: We evaluated the histopathologic differences between ruptured and unruptured epidermoid cysts, and their relationships. METHODS: We retrospectively examined 359 excision biopsy specimen diagnosed as epidermoid cyst from 1991 to 2011 at Department of dermatology at Daegu Catholic University Hospital. RESULTS: The mean cyst area was 38.89 mm(2) and the mean cyst area of the unruptured group was larger than that of the ruptured group. The mean wall thickness was 90.15 ?m and was thicker in ruptured group than in unruptured group. The correlation between cyst diameter and wall thickness had statistically negative correlation in unruptured and in ruptured group. In ruptured group, the cystic size of the cases with rete ridge was smaller than that of without rete ridge. The cyst wall thickness of the cases with rete ridge was thicker than that of the cases without rete ridge. LIMITATIONS: For comparative evaluation of sizes, randomly shaped cysts are assumed to be perfectly elliptic. And only those with more than 3/4 cystic wall remaining were included in the subject. CONCLUSION: When comparing the ruptured and the unruptured cyst, the rupture of cyst had significant relationship with increased cyst diameter and area, increased wall thickness, more cyst contents, and more wall changes. Moreover, the presence of rete ridge in ruptured cystic wall is a valuable variable to recognize the duration of the rupture.

Choledochal cyst. A case presentation Quiste de colédoco. Presentación de un caso  

Directory of Open Access Journals (Sweden)

Full Text Available Congenital dilatation of the bile duct and its incidence is a rare condition reported in one in 100 000 to 150 000 newborns. Current concern about the evolution of this process is that a cholangiocarcinoma might appear. The case of a female teenager of urban origin, who attended her health area polyclinic, because of a moderate 5 months pain in her high epigastrium and in her upper right abdomen is presented. The pain appeared always after eating accompanied by vomiting and it was self-relieved. An abdominal ultrasound indicated by the patient’s family doctor showed a liver cyst. It was decided to perform an abdominal computed tomography. Through this test a cyst at the pancreatic head was found. The patient was admitted in the emergency room of the ‘’Gustavo Aldereguía Lima’’ Hospital of Cienfuegos, where she was evaluated by the physicians in the Surgery Department. It was decided to treat her surgically. Anatomopathologic results showed chronic cholecystitis, choledochal cyst and nonspecific chronic inflammation.La dilatación congénita de las vías biliares y su incidencia es rara, se presenta un caso cada 100 000 a 150 000 nacimientos. La preocupación actual respecto a la evolución de este proceso, es que origine un colangiocarcinoma. Se presenta el caso de una adolescente de procedencia urbana, que acudió a  cuerpo de guardia de su área de salud, refiriendo que desde hacía aproximadamente 5 meses presentaba dolor  moderado en ¨la boca¨ del estómago y en la región superior derecha del abdomen que aparecía siempre después de ingerir alimentos, se aliviaba por sí solo y se acompañaba de vómitos. Su médico de familia  indicó ultrasonido abdominal, donde se observó un quiste en el hígado. Fue  trasladada al Cuerpo de Guardia del Hospital General Universitario Dr. Gustavo Aldereguía Lima, de Cienfuegos, donde fue valorada por el Servicio de Cirugía. Se decidió la realización de  tomografÍa axial computarizada de abdomen en la que se observó un quiste a nivel de la cabeza del páncreas. Se aplicó tratamiento quirúrgico. Los resultados anatomopatológicos mostraron colecistitis crónica, quiste de colédoco e inflamación crónica inespecífica.

El estudio anatomopatológico resulta ser compatible con el diagnóstico de quiste endodérmico. Se han descrito casos de evolución agresiva con diseminación y recidiva tras manipulación quirúrgica de la lesión; por lo tanto, el tratamiento debe consistir en la extirpación completa de la misma.

Abstract in english Endodermal cysts (EC) of the central nervous system are very uncommon lesions predominantly located in the spinal canal. Although rare, intracranial EC have been mainly described in the posterior fossa, with the supratentorial location considered exceptional.

A 62-year-old man presented with abnormal behaviour, di (more) sorientation and decreased level of consciousness after moderate head injury. Initial cranial CT scan revealed a large cyst in the left frontal region with marked midline shift. Emergency puncture and decompression of the cyst demonstrated a milky fluid with high protein levels. Cranial MRI after patient improvement confirmed the existence of the cystic lesion with less mass effect. Delayed surgery was performed with craniotomy and total removal of the cyst. Pathological examination confirmed the presence of a typical EC. Patient made a complete recovery on follow-up with no recurrence on postoperative MRIs. Differential diagnosis of EC based on radiological data is quite difficult. As aggresive behaviour of this condition has been described following incomplete resections, the treatment of choice is a radical removal of the cyst in one or two stages depending on patient clinical condition.

Estudio de la fertilidad y viabilidad de quistes hidatídicos ovinos/ Fertility and viability study of hydatid cysts from ovine  

Scientific Electronic Library Online (English)

Full Text Available Abstract in spanish FUNDAMENTO: La finalidad de este trabajo es analizar la fertilidad de los quistes hidatídicos de origen ovino, especie de gran interés epidemiológico en la hidatidosis, y la adecuación del gerbillo (Meriones unguiculatus) como modelo experimental para el estudio "in vivo" de dicha hidatidosis, fase preliminar de posteriores estudios terapeúticos. MÉTODOS: Se ha realizado un estudio de la fertilidad y viabilidad de quistes hidatídicos procedentes de pulmones e híga (more) dos de ganado ovino de Castilla y León a través del examen y evaluación de una serie de parámetros entre los que figura la producción de una hidatidosis secundaria experimental en animales de laboratorio. RESULTADOS: El índice quístico total obtenido fue de 8,57 quistes por ovino infestado (5,97 quistes por pulmón infestado y 5,57 quistes por hígado infestado). El porcentaje de fertilidad obtenido en los quistes hidatídicos de origen ovino que contenían protoescólex viables "in vitro" fue del 43,97% (43,02% en los quistes pulmonares y 46,16% en los quistes hepáticos). La viabilidad "in vivo" de los protoescólex seleccionados se puso de manifiesto al producirse en el 100% de los gerbillos infectados una hidatidosis secundaria experimental. CONCLUSIONES: Se destaca la validez de los criterios utilizados para estudiar la viabilidad "in vitro" de los protoescólex procedentes de quistes hidatídicos de origen ovino. La hidatidosis secundaria producida en gerbillos nos conduce a considerarlos como especie de experimentación adecuada para la investigación "in vivo" de la hidatidosis de origen ovino. Abstract in english BACKGROUND: The purpose of this work is to analyze the fertility of the hydatid cysts from ovine, animal species of great epidemiological interest in the hydatid disease, and the ability of the gerbil (Meriones unguiculatus) as model experimental for the study "in vivo" of this hidatyd disease as preliminary phase of therapeutic studies. METHODS: It has been carried out a study of the fertility and viability of hydatid cysts from lungs and livers of ovine from Castilla an (more) d Leon by examination and evaluation of parameters among these is the production of a secondary hydatid disease in laboratory animals. RESULTS: The total cystic index was 8.57 cysts by infested ovine (5.97 cysts by infested lung and 5.57 cysts by infested liver). The fertility percentage obtained in hydatid cysts from ovine with "in vitro" viables protoescoleces was 43.97% being 43.02% in pulmonary cysts and 46.16% in hepatic cysts. The viability of protoscoleces was demonstrated by production of a secondary hydatid disease in 100% of gerbils infested. CONCLUSIONS: It is emphasized the validity of the criteria used to study the viability "in vitro" of the protoescoleces from hydatid cysts of origin ovine. The secondary hydatid produced in gerbils leads us to consider them as experimental animal for investigation "in vivo" of hydatid disease of origin ovine.

The hormonal control of testicular descent.  

Science.gov (United States)

The migration of the testes from the abdomen into the scrotum requires both an anatomical change in connecting structures and regulating signals to mediate this process. The gubernaculum is the principle structure in testicular descent. Its development appears to be controlled by insulin-like hormone 3 (INSL3) and androgen. This review article summarises the role of INSL3 and androgen in testicular descent. It also analyses the contribution of other hormones such as Mullerian inhibiting substance (MIS) and oestrogen to testicular descent. Furthermore, it reiterates findings that hormonal activation of the nervous system leads to neuropeptide secretion and further manipulation of this process. PMID:19696713

Methods: Descriptive study of a testicular infection by an atypical unknown germ in a patient, which was identified and diagnosed thank to the use of Polymerase chain reaction (PCR). We performed a bibliographic search of similar cases. Results: We only found one case of pleural infection by Corynebacterium Thommsenii in the human being, with no case of genitou (more) rinary involvement described. Conclusions: To date there is only one case described of infection by Corynebacterium Thommsenii in human beings, possibly due to underdiagnosis for the slow grow of this pathogen. Genetic amplification methods by PCR should be demanded more frequently by clinicians because they provide an advance in the microbiologic diagnosis is slow-growing pathogens

Bilateral testicular microlithiasis with a unilateral testicular germ cell tumor: a case report.  

Science.gov (United States)

There is an important association between testicular microlithiasis and germ cell tumors. Ultrasound findings of 1-3 mm echogenic foci within the testicular parenchyma may be noted. Testicular microlithiasis in the general population without germ cell tumors or cryptorchidism has been estimated between 0.05 and 0.6%. However, findings of microlithiasis in concordance with germ cell tumors can be as high as 40%. We present the case report of a man with bilateral testicular microlithiasis and a unilateral germ cell tumor. Discussion of the relationship between these two conditions is also reviewed.

Correlación clínico-citohistológica de los quistes congénitos cervicales Clinical-cytohistological correlation of cervicofacial congenital cysts  

Directory of Open Access Journals (Sweden)

Full Text Available Objetivo: Determinar la efectividad de los diagnósticos clínico y citológico en los quistes congénitos cervicofaciales. Método: Se realizó un estudio retrospectivo de los pacientes con diagnóstico clínico, citológico y/o histológico de quiste tirogloso, branquial y dermoide, atendidos en el Hospital Universitario «Arnaldo Milián Castro», durante cinco años. Se calculó la sensibilidad, especificidad y seguridad del diagnóstico clínico y la biopsia por aspiración con aguja fina (FNAC) para cada quiste. Resultado: La seguridad del diagnóstico clínico fue de 94,1%, 92,2% y 98% para los quistes tirogloso branquial y dermoide respectivamente. Encontramos mayor tendencia al error clínico en los quistes branquiales, donde las confusiones más frecuentes se presentan con linfoadenopatías inflamatorias. La seguridad de la biopsia por aspiración con aguja fina fue de 96,1% y 94,1% para los quistes tirogloso y branquial respectivamente. Conclusiones: El diagnóstico clínico no es suficiente en ocasiones, por lo que es preciso recurrir a medios diagnósticos complementarios, como la biopsia por aspiración con aguja fina; sin embargo esta prueba no es 100% segura.Objective: To determine the effectiveness of clinical and cytological diagnosis in congenital cysts located in head and neck. Method: We were carried out a retrospective study of patients with clinical, cytological or histological diagnosis of thyroglossal, branchial and dermoid cyst, assisted in the University Hospital Arnaldo Milián Castro", during five years. It was calculated the sensibility, specificity and security of the clinical diagnosis and the Fine Needle Aspiration Biopsy for each cyst. Result: The security of the clinical diagnosis it was respectively of 94,1%, 92,2% and 98% for the thyroglossal, branchial and dermoid cysts. We find bigger tendency to the clinical error in branchial cysts, where the most frequent confusions are presented with inflammatory linfoadenopathy. The security of the Fine Needle Aspiration Biopsy was of 96,1% and 94,1% for the thyroglossal and branchial cysts respectively. Conclusions: Clinical diagnosis is not enough in occasions, for what is necessary to appeal to means complementary diagnoses, as the Fine Needle Aspiration Biopsy; however this test is not 100% sure.

Testicular myeloid sarcoma: case report  

Directory of Open Access Journals (Sweden)

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

Quistes dermoides nasoetmoidales manejo quirúrgico Surgical management of nasoethmoidal dermoide cysts  

Directory of Open Access Journals (Sweden)

Full Text Available Los quistes dermoides nasoetmoidales son malformaciones congénitas infrecuentes, de origen ectodérmico. Clínicamente pueden presentarse como un nódulo subcutáneo y/o como un orificio fistuloso cutáneo con pelos, a cualquier nivel de la línea media nasal. A diferencia de los dermoides de otras localizaciones, existe la posibilidad de compromiso de estructuras profundas y extensión intracraneal, pudiendo asociarse a graves complicaciones, como meningitis y abscesos cerebrales. Por este motivo, los dermoides nasoetmoidales, demandan una adecuada evaluación imaginológica para planificar el abordaje quirúrgico, que permita la extirpación completa de la lesión. Por las características singulares de los quistes dermoides nasoetmoidales se consideró de interés presentar 3 casos clínicos de esta poco frecuente e interesante patología, tratados en la Unidad de Cirugía Plástica del Hospital de Niños Dr. Roberto del Río, entre los años 1999 y 2001. Se discuten posteriormente algunos aspectos relacionados con su epidemiología, etiopatogenia, evaluación y manejo quirúrgicoNasoethmoidal dermoide cysts are infrequent congenital malformations of ectodermal origin. Clinically they can present as a subcutaneous nodule and/or a cutaneous fistula with hair at whatever level in the nasal midline. Differing from dermoide cysts in other parts there exists the possibility of deep structures compromise and intracranial extension, associated ar not severe complications such as meningitis and cerebral abscesses. For this reason nasoethmoidal dermoide cysts need a meticulous radiological evaluation in order to plan surgery that allows the complete removal of the lesion. For these singular characteristics we consider it of interest to present 3 cases of this infrequent and interesting pathology, treated in the Plastic Surgery Unit in the Roberto del Río Childrens Hospital between 1999 and 2001. We discuss some aspects of epidemiology, aetiopathology and surgical evaluation and management.

Wegener's granulomatosis diagnosed by testicular biopsy.  

UK PubMed Central (United Kingdom)

Urogenital involvement, other than the kidneys, is extremely rare in Wegener's granulomatosis (WG) and occurs in less than 1% of the cases. When encountered it is confined to prostate, bladder, urethra, cervix, and vagina. Granulomatous infiltration of the testis from WG has not been cited in the medical literature. We report a case of WG in a Hispanic male who presented with sensorineural hearing loss and hemoptysis. He had a pulmonary lesion and a painless right testicular mass, which was found to have necrotizing granulomas on excisional biopsy. This may be the first reported case of WG diagnosed by testicular biopsy as testicular involvement is rare in WG. We believe that the actual incidence of testicular involvement in WG may be higher as genital examination may be ignored during routine physical examinations.

[Testicular torsion before 6 hours. I  

UK PubMed Central (United Kingdom)

OBJECTIVE: To analyze the characteristics of testicular torsion within the first 6 hours, and to emphasize the need for early diagnosis and treatment. METHODS: The records of 33 patients treated for testicular torsion within the first 6 hours were reviewed. We evaluated the reason for consultation, previous patient history, clinical features, urinalysis findings, diagnostic methods and surgical findings. RESULTS: The most common reason for consultation was scrotal pain. Twelve patients had a previous history of ascending testis. Urinalysis was normal in 25 patients. Diagnosis was based on the clinical findings. Thirty-two testes were preserved. CONCLUSIONS: Diagnosis of testicular torsion within the first 6 hours are usually based on the clinical findings. Early treatment can achieve testicular viability.

[Testicular torsion after 12 hours. III  

UK PubMed Central (United Kingdom)

OBJECTIVE: To analyze the damage caused by testicular torsion after 12 hours. METHODS: The records of 59 patients treated for testicular torsion after 12 hours were reviewed. We evaluated the reason for consultation, previous patient history, clinical features, urinalysis findings, diagnostic methods and surgical findings. RESULTS: The reason for consultation was scrotal pain in 81% of the patients: 61% were referred to the left testis. Seventeen percent of the patients had a previous history of ascending testis. Scrotal US was useful in making the diagnosis in 92% of the cases. CONCLUSIONS: Testicular damage or loss can occur if testicular torsion is diagnosed after 12 hours. The importance of early diagnosis and treatment is emphasized.

Estrogen signaling in testicular cells.  

Science.gov (United States)

Aromatase transforms irreversibly androgens into estrogens and is present in the endoplasmic reticulum of various tissues including the mammalian testis. In rat all testicular cells except peritubular cells express aromatase. Indeed in adult rat germ cells (pachytene spermatocytes and round spermatids) we have demonstrated the presence of a functional aromatase (transcript, protein and biological activity) and the estrogen output is equivalent to that of Leydig cells. In addition in the adult rat, transcripts of aromatase vary according to the germ cell type and to the stages of seminiferous epithelium. By contrast with the androgen receptors mainly localized in somatic cells, estrogen receptors (ERs) are described in most of the testicular cells including germ cells. Moreover, besides the presence of high affinity ER? and/or ER?,? a rapid membrane effect has been recently reported and we demonstrated that GPR30 (a transmembrane intracellular estrogen receptor) is expressed in adult rat pachytene spermatocytes. Therefore estrogens through both GPR30 and ER? are able to activate the rapid EGFR/ERK/c-jun signaling cascade, which in turn triggers an apoptotic mitochondrial pathway involving an increase in Bax expression and a concomitant reduction of cyclin A1 and B1 gene levels. In another study in round spermatids of adult rat we have shown that the rapid membrane effect of estradiol is also efficient in controlling apoptosis and maturation / differentiation of these haploid germ cells. In man the presence of a biologically active aromatase and of estrogen receptors has been reported in Leydig cells, but also in immature germ cells and ejaculated spermatozoa. Thus the role of estrogen (intracrine, autocrine and / or paracrine) in spermatogenesis (proliferation, apoptosis, survival and maturation) and more generally, in male reproduction is now evidenced taking into account the simultaneous presence of a biologically active aromatase and the widespread distribution of estrogen receptors especially in haploid germ cells.

Testicular blood flow in varicocele  

International Nuclear Information System (INIS)

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

Familial testicular cancer and urogenital developmental anomalies.  

Science.gov (United States)

In a case-control study of testicular cancer, 6 of 269 cases (2.2%) reported a first-degree relative with testicular cancer, compared to 1 of 259 controls (0.4%). Fathers and brothers of testicular cancer cases had a six-fold elevated risk of developing a testicular malignancy compared to men in the general population. Cryptorchidism was reported in a first-degree relative in 1 (17%) of the familial cases versus 7 of 259 (2.7%) controls and 14 of 263 (5.3%) cases with a negative family history for testicular cancer. One half of the 6 familial cases reported a first-degree relative with a groin hernia (all surgically repaired before age 12), compared to 12.7% of 259 controls and 10.3% of 263 nonfamilial cases. Three familial clusters identified through the case-control study were selected for clinical evaluation. One of the 6 surviving males with testicular cancer in these 3 families had undergone orchiopexy and inguinal herniorrhaphy at age 6 years, and one had a hydrocele associated with his testicular tumor. Of the 12 living fathers and brothers of these 6 men, 3 reported childhood inguinal hernias, two with coexisting hydroceles. One additional hernia and two additional hydroceles were detected during urologic evaluation of these healthy relatives. The high prevalence of cryptorchidism, inguinal hernias, and hydroceles among men in these families suggests that an underlying alteration in urogenital embryogenesis may be associated with the familial predisposition to testicular neoplasia.

Imaging of testicular germ cell tumours.  

UK PubMed Central (United Kingdom)

In testicular germ cell tumour (GCT), imaging plays a central role in assessment of tumour bulk, sites of metastases, monitoring response to therapy, surgical planning and accurate assessment of disease at relapse. The primary modality used for imaging patients with GCT is computed tomography (CT) but plain film radiography, ultrasound, magnetic resonance imaging (MRI) and positron emission tomography (PET) may all have roles to play. This article reviews the role of imaging of testicular germ cell tumours.

Occupational Causes of Testicular Cancer in Adults  

Directory of Open Access Journals (Sweden)

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

[Giant epidermoid cyst of the skull with extra and intracranial extension. A case report].  

Science.gov (United States)

Intradiploic epidermoid cyst of the skull is a rare clinical entity that can exceptionally grow to a large size with intracranial extension. The authors report the case of a 38-year-old man with a giant epidermoid cyst of the parietal bone with extra and intracranial extension, presenting with focal neurological symptoms. The diagnosis was suggested at imaging (skull radiographs, CT and MRI), and confirmed at histology. Complete removal of the cyst and its capsule was performed followed by cranioplasty. Postoperatively, the patient was discharged free of symptoms. CT scan provides good evaluation of the bony lesion and may suggest intracranial extension. MRI is superior for evaluation of cerebral compression. The pathogenesis, clinical presentation, diagnostic evaluation and therapeutic management of these rare lesions are reviewed. PMID:12447144

Angiofibromas with multiple epidermoid cysts in tuberous sclerosis: new mutation or post-traumatic?  

UK PubMed Central (United Kingdom)

Tuberous sclerosis is a genetic multisystem disorder characterized by widespread hamartomas in several organs. Clinically, more than 90% of affected patients have skin lesions including facial angiofibromas, periungual fibromas, hypomelanotic macule, etc. Periungual fibroma is one of the major diagnostic criteria of tuberous sclerosis and has the same pathology (angiofibroma) as the facial papules. We herein describe an interesting histologic variant of angiofibromas coupled with multiple epidermoid cysts in a 33-year-old patient with tuberous sclerosis.

Efectos de la densidad de cultivo sobre la edad de reproducción y producción de quistes del camarón Duende Streptocephalus mackini  

Directory of Open Access Journals (Sweden)

Full Text Available Durante el estudio se cultivaron nauplios del camarón duende (Streptocephalus mackini) en tres peceras con 200 L de agua dulce, a densidad de 100 org.L?1, recambios de agua de 25% diarios, y condiciones semicontroladas de temperatura (27 ± 3°C), pH 7-8.5, fotoperiodo (12 L: 12 O), oxígeno disuelto a saturación, y alimentación a base de microalga Chorella sp (1 × 106 cel. mL?1), para evaluar la velocidad de crecimiento y establecer su ecuación. Posteriormente se determinó el efecto de la densidad de cultivo en la edad reproductiva y producción de quistes de preadultos del camarón (1:1 macho: hembra) durante 21 días. Se probaron cuatro tratamientos con tres réplicas: T1-50 org. L?1, T2-100 org. L-1, T3-150 org. L?1 y T4-200 org. L?1, en 12 recipientes de 3 L de capacidad y condiciones ambientales semicontroladas. Los organismos iniciaron su etapa reproductiva, en promedio, a los diez días de su nacimiento, y continuó hasta el fi nal del ensayo. Se encontró que la longitud teórica máxima bajo las condiciones prevalecientes fue de 26.49 mm, el valor de la constante de catabolismo fue de 0.034 mm y la talla al tiempo de nacer de 0.896 mm. Los resultados indican que la densidad afectó directamente la producción de quistes y supervivencia. Las hembras que permanecieron en T1 produjeron un número signifi cativamente superior de quistes (178.01 quistes/hembra) con respecto a los tratamientos restantes (? = 0.05). La supervivencia de los organismos en T1 y T2 (74.76% y 71.33%) indican que la producción masiva de la especie puede ser económicamente factible, bajo las condiciones que se probaron.

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)

Freehand dynamic endoscopic resection of an epidermoid tumor of the cerebellopontine angle: technical case report.  

UK PubMed Central (United Kingdom)

OBJECTIVE: In the last 10 years, experience with endoscopic transsphenoidal surgery for the treatment of sellar and perisellar lesions has highlighted advantages brought about by the endoscope for less-invasive procedures. Focusing on these advantages, there is increasing interest in endoscope use for treatment of lesions located in other regions such as the cerebellopontine angle (CPA). Epidermoid tumors, especially those located on the CPA, resulting from their avascular and noninfiltrative nature, appear particularly suited to being treated using an endoscopic approach. CLINICAL PRESENTATION: A 37-year-old man with a 2-year history of left trigeminal neuralgia responded poorly to medical therapy. Magnetic resonance imaging scans revealed a left CPA lesion compatible with an epidermoid tumor, and he was admitted for surgical treatment. TECHNIQUE: We report a patient who underwent freehand dynamic endoscopic resection of an epidermoid tumor of the CPA. This technique requires two surgeons to work in close cooperation: the "navigator," who holds the endoscope and makes fine position adjustments, and the "pilot," who uses both hands to perform the procedure itself under dynamic endoscopic view. CONCLUSION: The patient's postoperative course was uneventful. The trigeminal neuralgia completely resolved, and postoperative control magnetic resonance imaging scans demonstrated no residual lesion. The benefits of endoscopic treatment for CPA lesions, with special emphasis on the dynamic aspect of this new technique, are discussed.

The great mimic: syphilis mimicking testicular tumour. Conservative management using antibiotics alone with testicular sparing.  

UK PubMed Central (United Kingdom)

We present the case of a 47-year-old man who attended a genitourinary (GU) medicine clinic with posthitis and a painless testicular mass on examination. Initial ultrasound revealed a 2-cm well-defined hypoechoic mass within the right testis and he was referred to urology on suspicion of malignancy. Subsequent syphilis serology was positive and the penile lesion and testicular mass were felt to be consistent with syphilis. After liaising with the urology department, and in view of negative tumour markers (lactate dehydrogenase, alfa-fetoprotein and human chorionic gonadotrophin) and known penicillin allergy, he was managed conservatively with four weeks of oral doxycycline. Follow-up ultrasound scans revealed adequate response of the testicular mass, with the last scan, performed at 10 months post-treatment, showing complete resolution. This is the first documented case of conservative management of a testicular syphilitic lesion using antibiotics alone with testicular sparing.

Follow-up ultrasound scans revealed adequate response of the testicular mass, with the last scan, performed at 10 months post-treatment, showing complete resolution. This is the first documented case of conservative management of a testicular syphilitic lesion using antibiotics alone with testicular sparing. PMID:23970712

Accuracy of Prader orchidometer in measuring testicular volume.  

UK PubMed Central (United Kingdom)

BACKGROUND: Seminiferous tubules comprise 80-90% of testicular mass. Thus, the testicular volume is believed to be an index of spermatogenesis. Therefore, accurate testicular volume is one way to assess testicular function. OBJECTIVE: To determine the accuracy of Prader orchidometer for measuring the testicular volume by comparing the resultant measurement with the actual testicular volume in humans. MATERIALS AND METHODS: The testicular volumes of 121 testes from 62 patients with prostate cancer (mean age 72.74 ± 9.38 years) were measured using Prader orchidometer before therapeutic bilateral orchidectomy. The actual testicular volumes were then determined by water displacement of the testis. RESULTS: The mean testicular volume of the 121 testes was 10.60 ± 3.5 ml and 13.26 ± 5.2 ml for water displacement and Prader orchidometer measurements, respectively. A strong correlation was found between the actual testicular volume and volumes obtained by Prader orchidometer ( r = 0.926, P = 0.0001). The Prader orchidometer however, over-estimated the mean actual testicular volume by 2.66 ± 2.37 ml (25.10%). CONCLUSION: The result of this study has shown that measuring the testicular volume by Prader orchidometer overestimates the actual testicular volume.

Testicular cancer in US Navy personnel  

Energy Technology Data Exchange (ETDEWEB)

The risk of the development of testicular cancer is greatest in white men aged 20-29 years. The United States Navy is one of the largest populations of men in this high-incidence age group to receive health care with a centralized, computer-based medical records system. There were 2,275.829 person-years at risk in white male enlisted personnel involved in approximately 100 occupations in the US Navy during 1974-1979. Incident cases of testicular cancer (n = 143) were identified in this population using computerized hospitalization data maintained at the Naval Health Research Center, San Diego. Cases were verified through review of original medical records and Naval Medical Board findings. Age-adjusted incidence rates of testicular cancer in US Navy personnel did not differ significantly from those of the United States population (3.7 vs 3.9 per 100,000, respectively), and there were no significant differences in age-specific rates. US Navy age adjusted incidence rates of testicular cancer did not increase with length of service. However, two naval occupations appeared to have significantly increased risk: aviation support equipment technicians (standardized incidence ratio (SIR) = 6.2, p = 0.001) and enginemen (SIR = 2.6, p = 0.01). Job-related exposures common to these two occupations include exposure to gasoline and diesel fuel, and their exhaust products; the authors believe these exposures may be associated with increased risk of testicular cancer.

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

Science.gov (United States)

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

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

Science.gov (United States)

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

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.

Scrotal trauma: a cause of testicular atrophy.  

UK PubMed Central (United Kingdom)

Scrotal trauma is often mentioned as a cause of testicular atrophy yet there have been few studies documenting the effect of scrotal trauma on testicular size months or years following injury. We performed clinical and sonographic examinations in 10 patients who had suffered blunt scrotal trauma. A significant reduction in volume of the injured testis was observed in 5/10 cases at follow-up sonography. In two cases the affected testis was heterogeneous and colour flow Doppler examination showed reduced flow. In three cases the testis was homogeneous but reduced in volume and in the remaining five cases the affected testis appeared normal. We conclude that testicular atrophy is a sequel of scrotal trauma and occurred in 50% of patients in this study.

[Ectopic testicular parenchyma in albugineal tunic].  

UK PubMed Central (United Kingdom)

We introduce a male patient with bilateral chryptorchidism submitted to surgery; during the intervention, macroscopically round macules were seen in the outer surface of both testes. In the round macules histological study, groups of seminiferous tubules were observed, including stroma and Leydig's intestitial cells surrounded of tunica albuginea, isolated from the rest of testicular parenchymal tissue; the diagnosis "Ectopic testicular parenchyma tissue" was confirmed by histopathological study. Due to the seminiferous tubules are surrounded by the tunica albuginea, with no apparent connection to the rest of the testicular parenchyma, a long-term assessment is required, both during puberty as well as in adulthood; owing to that can mislead and make unnecessary laparotomies and orchiectomies in the future.

Testicular hydrocele treated by bismuth phosphate injection.  

Science.gov (United States)

Thirty-eight testicular hydroceles were treated by injection with 0.2-0.4 g of bismuth phosphate. The follow-up was completed in 32 cases, 17 (53%) of which showed complete regression although one patient had to wait 24 months for full regression. Eight patients (25%) showed clinical improvement and one patient (3%) had residual scrotal tenderness after otherwise successful treatment. Six patients (19%) did not improve and were treated surgically. The method may present an alternative to surgery in elderly patients with testicular hydrocele. PMID:3384609

[Testicular graft on the chick embryo].  

UK PubMed Central (United Kingdom)

A testis from an 18-day-old chick embryo was transplanted into the extra-coelomic cavity of 3-4-day-old hosts. The embryos surviving at 17 days were sacrificed and their genital system was examined. Testis grafting produced inhibition of testicular development. Development of the female gonads was also inhibited. A more or less complete modification of sex was associated with this inhibition. The left ovary lost its cortex, but its medulla remained mostly ovarian in structure. The right gonad frequently acquired a typical testicular structure. These results confirm the possibility of obtaining sex reversal in the female chick embryo by testis grafting.

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 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 tumores 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 (more) 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 morbidity that takes place and the absence of reconstructive necessity. Objective: To analyze the postoperative evolution, in the patients treated by oral and oropharyngeal epid (more) ermoid 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.

Abstract in english 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.

[Epidermoid cyst of the 4th ventricle. Apropos of a case in a child and review of the literature].  

Science.gov (United States)

A 6 year-old child was admitted for a recurrent bacterial meningitis at Proteus Morganii. She was treated with antibiotics. The C.T. Scanner showed a midline low-density lesion, with a mild annular contrast uptake in the posterior fossa. M.R.I. showed the lesion and revealed a skin-bone-dura fistula. The surgical resection was complete. It was an epidermoid tumor. Intracranial epidermoid tumors constitute about 1% of brain tumors and are considered to be congenital. Epidermoid tumors of the 4th ventricle are exceedingly rare in childhood. The authors reviewed the literature and discuss the pathogeny, the radiographic diagnosis and the treatment of these tumors.

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.

Dopplex Sonographic Evaluation of Variococele–Related Testicular Atrophy  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction & Objective: Varicocele is often mentioned as a common cause of testicular atrophy. The aim of this study was to evaluate varicocele-related testicular atrophy with Duplex sonography.Materials & Methods: Seventeen patients with testicular atrophy due to varicocele were included into the study.Results: Echogenisity of the atrophic testis was homogeneous. Mean peak systolic velocities (PSV) in intratesticular arteries for atrophic and normal testes were 5.57±2.03 cm/s and 6.49 ± 1.37 cm/s, respectively. The difference was not significant (P > 0.05).Conclusion: Varicocele-related testicular atrophy is not associated with testicular parenchymal heterogeneity, and does not affect the intra-testicular and testicular arterial PSV.

Spermatogenesis and testicular tumours in ageing dogs.  

UK PubMed Central (United Kingdom)

Spermatogenesis was examined in testes from 74 dogs of various breeds without clinically detected testicular disease. A modified Johnsen score system was used to determine whether spermatogenesis deteriorates with ageing. The diameter of seminiferous tubules was measured in dogs without testicular disease to examine other possible effects of ageing on tubular performance. There appeared to be no relation between age and these variables. The influence of testicular tumours on spermatogenesis was also investigated in both affected and unaffected testes. The testes of 28 dogs with clinically palpable tumours and 21 dogs with clinically non-palpable tumours were investigated. In cases of unilateral occurrence of a tumour, impairment of spermatogenesis was observed only in the affected testis of dogs with clinically detected tumours. Bilateral occurrence of tumours, whether detected clinically or non-clinically, was associated with severe impairment of spermatogenesis. The prevalence of tumours increased during ageing. Eighty-six per cent of the clinically detected and 57% of the non-clinically detected tumours were found in old dogs. Multiple types of tumour and bilateral occurrence were very common. Seminomas and Leydig cell tumours were more frequent than Sertoli cell tumours. It was concluded that spermatogenesis per se did not decrease during ageing in dogs but the occurrence of testicular tumours increased with ageing and affected spermatogenesis significantly, as reflected by a lower Johnsen score.

Automated sonographic evaluation of testicular perfusion  

Energy Technology Data Exchange (ETDEWEB)

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.

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)

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

Directory of Open Access Journals (Sweden)

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

Differentiation of testicular diseases via dynamic MRT  

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

Characterization of amino acid transport system L in HTB-41 human salivary gland epidermoid carcinoma cells.  

UK PubMed Central (United Kingdom)

BACKGROUND: The amino acid transport system L is a major nutrient transport system that is responsible for transport of neutral amino acids, including several essential amino acids. The current study attempted to investigate the expression and functional characterization of amino acid transport system L in HTB-41 human submaxillary salivary gland epidermoid carcinoma cells. MATERIALS AND METHODS: RT-PCR analysis, Western blot analysis and amino acid transport measurements were used. RESULTS: The HTB-41 cells expressed the L-type amino acid transporter 1 (LAT1) together with its associating protein heavy chain of 4F2 antigen (4F2hc) in the plasma membrane, whereas the HTB-41 cells did not express the L-type amino acid transporter 2 (LAT2). The uptakes of [14C]L-leucine were Na+-independent and completely inhibited by a system L selective inhibitor, 2-aminobicyclo-(2,2,1)-heptane-2-carboxylic acid (BCH). The affinity of [14C]L-leucine uptake and the inhibition profile of [14C]L-leucine uptake by various L-amino acids in the HTB-41 cells were comparable with those for the LAT1 expressed in Xenopus oocytes. CONCLUSION: The transport of neutral amino acids including several essential amino acids into the HTB-41 human submaxillary salivary gland epidermoid carcinoma cells are mediated by LAT1.

Tratamiento laparoscópico de quistes renales simples sintomáticos/ Laparoscopic treatment of symptomatic renal cysts  

Scientific Electronic Library Online (English)

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

Quiste de paratiroides recurrente: A propósito de un caso/ Recurrent parathyroid cyst: A clinical case  

Scientific Electronic Library Online (English)

Full Text Available Abstract in spanish El quiste paratiroideo es una entidad infrecuente, tanto que solamente unos 200 casos han sido descritos. Puede ser funcional y no funcional. Los estudios de imagen no nos aclaran si la procedencia es paratiroidea o de otro origen y el diagnóstico se establece con el análisis del líquido extraído en la punción aspiración, donde se aprecian altas concentraciones de PTH. El tratamiento es la cirugía en los funcional y la punción aspirativa en los no funcionales, que (more) suelen solucionarse con una sola o a veces en otra repetida, dejándose para la cirugía los pocos recurrentes. Presentamos el caso de comportamiento recurrente y su evolución natural, donde la paciente rechaza la cirugía, siendo necesarias punciones repetidas. Después de 10 años no se ha malignizado ni cambiado su estado funcional, siendo necesario realizar repetidas punciones aspirativas cada 2-3 meses por molestias locales. Abstract in english The parathyroid cyst is a very infrequent entity, so much so that only round about 200 cases have been described up to now. It can be functional and non-functional. The studies of image don't clarify to us if procedence becomes of parathyroid or it has another origin, and the diagnosis is made with the analysis come from the liquid obtained in the puncture aspiration, where high PTH's concentrations are seen. Surgery is the treatment for functional cysts and the puncture (more) aspiration for non- functional, the fact that they use to get solved with only one but sometimes is necessary to repeated it, even more than one time, keeping for the surgery when recurrent. We presented a clinical case of recurrent parathyroid cyst and his natural evolution, due to patient rejects surgery, being necessary repeated punctures. It hasn't become malignant after 10 years and his functional status wasn't changed, being necessary to accomplish repeated punctures aspirations each 2-3 months for local bothers.

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

Scientific Electronic Library Online (English)

Full Text Available 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 importantes alteraciones testiculares bilaterales tanto ecográficas como anatomopatológicas, pero sin evidenciar tumor. Pese a las controversias que detallamos, nuestra o (more) pción 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 demonstrated abnormalities in both testes, but without evidence of tumor. The patient received chemotherapy and underwent surgery of the residual retroperitoneal mass and bilateral (more) 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.

Carcinoma epidermoide de la conjuntiva, su posible asociación con el papilomavirus humano Epidermoid carcinoma of the conjunctiva, its possible association with human papillomavirus  

Directory of Open Access Journals (Sweden)

Full Text Available El carcinoma epidermoide de células escamosas de la conjuntiva ocupa el segundo lugar en frecuencia de los tumores malignos oculares. Este tumor puede tener una evolución letal si no es diagnosticado y tratado en etapas tempranas. Recientes reportes de la literatura, muestran la presencia del papilomavirus humano 16 (PVH 16) en displasias epiteliales conjuntivales y carcinoma escamoso, este virus puede desempeñar un papel importante en el desarrollo de lesiones benignas y malignas de la conjuntiva. Sin embargo, la información es escasa y contradictoria, por lo que es interés nuestro estudiar un grupo de ellas. Se determinó la presencia de los PVH 16 y 18 por la técnica de PCR, se halló la presencia de los tipos 16 (66,6 %) y 18 (66,6 %) en lesiones premalignas mientras que en las malignas fue del 50 % para el tipo 16 y del 25 % para el tipo 18. Se demostró la existencia de infección viral por papiloma en lesiones de la conjuntiva, con una mayor carga viral en las lesiones premalignas lo que pudiera ser un factor necesario para la transformación maligna en esta localización.The epidermoid squamous cell carcinoma of the conjunctiva occupies the second place in frequency among the occular malignant tumors. This tumor may have a lethal evolution if it is not diagnosed and treated early. Recent reports of literature show the presence of human papillomavirus 16 (HPV) in conjunctival epithelial displasias and squamous cell carcinoma. This virus may play an important role in the development of bening and malignant lesions of the conjunctiva. However, the information is scarce and contradictory and that´s why we are interested in studying a group of them. The presence of HPV16 and 18 was determined by using the PCR technique. Types 16 (66.6 %) and 18 (66.6 %) were found in premalignant lesions, whereas 50% of type 16 and 25 % of type 18 were observed in malignant lesions. It was proved the existance of viral infection due to papilloma in conjunctiva lesions, with a higher viral burden in the premalignant lesions, which may be a necessary factor for the malignant transformation in this localization.

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.

Severe Testicular Atrophy Does Not Affect the Success of Microdissection Testicular Sperm Extraction.  

UK PubMed Central (United Kingdom)

INTRODUCTION AND OBJECTIVES: Men with azoospermia and severe testicular atrophy may be counseled to avoid sperm retrieval due to perceived limited success. We evaluated the outcomes of microdissection testicular sperm extraction (micro-TESE) in men with severe testicular atrophy (volume ? 2 mL). METHODS: We reviewed the records of 1127 men with nonobstructive azoospermia who underwent micro-TESE followed by intracytoplasmic sperm injection. The men were classified into three groups based on average testicular volume (mL), ?2, >2-10, >10. Sperm retrieval, clinical pregnancy, and live birth rates were calculated. The clinical features evaluated included age, FSH level, history of cryptorchidism, Klinefelter syndrome, varicocele, and testicular histology from diagnostic biopsy. RESULT(S): Testicular sperm were successfully retrieved in 56% of the men. Sperm retrieval rates (SRR) in men with testicular volumes of ?2, >2-10, and >10 mL was 55%, 56% and 55% respectively. Of those men who had sperm retrieved, clinical pregnancy and live birth rates were similar in the three groups (55.2%, 50.0%, and 47.0%; and 47.2%, 43.0% and 42.2% respectively). Of the 106 men with average testis volume ? 2 mL bilaterally, men who had sperm retrieved were younger (31.1 vs. 35.2 years), and were more likely to have a history of Klinefelter syndrome (82.2% vs 55.6%) compared to those in whom sperm was not found (p < 0.05). Men in this group had a higher prevalence of Klinefelter syndrome than men with testis >2 mL (72.6% vs 5.3%, p<0.0001). Men younger than 30 years with Klinefelter syndrome had a higher SRR (81.8%) compared to men older than 30 without Klinefelter syndrome (33%, p<0.01). There was no cut-point for age beyond which sperm could not be retrieved in men with small testes. On multivariable analysis, younger age was the only preoperative factor associated with successful sperm retrieval in men with small testes (<2mL). CONCLUSION(S): Testicular volume does not affect sperm retrieval rates at our center with micro-TESE. For men with the smallest volume testes, those younger men with Klinefelter syndrome had the highest sperm retrieval rates. Severe testicular atrophy should not be a contraindication for micro-TESE.

Young men's knowledge of testicular cancer and testicular self-examination: a lost opportunity?  

UK PubMed Central (United Kingdom)

Testicular cancer remains the most commonly occurring cancer in young men (aged 20-45 years) and recent trends suggest an increase throughout the western world. Whilst testicular cancer is highly treatable late diagnosis resulting in poorer treatment outcomes remains a problem. Testicular self-examination (TSE) a procedure whereby young men can routinely systematically examine their testicles has been advocated as a particularly effective health education intervention. This study aimed to establish the knowledge of testicular cancer and prevalence of TSE practice amongst young men. A descriptive survey approach using a 16-item self-report questionnaire was administered to a convenience sample of 203 male undergraduate and postgraduate students at the University of Huddersfield. Results indicated that the majority of the respondents were either uninformed or misinformed about the risks and symptoms of testicular cancer although 78% indicated an interest in accessing information. Only 32% had prior knowledge of TSE, 22% practiced TSE, and worryingly only a single respondent was able to recognize the correct procedure and indicated he regularly practiced TSE. Sixty-eight per cent indicated that TSE should be a part of general health assessments for men. Although some critics of TSE argue the cost of teaching TSE outweighs the benefits in terms of early diagnosis this study suggests that young men may be willing to participate in an aspect of personal health surveillance. If this is the case then low cost strategies to increase impact on the target audience should be considered.

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.

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.

Cavernous hemangioma of the testis mimicking a testicular teratoma.  

UK PubMed Central (United Kingdom)

In this study we report a case of cavernous hemangioma of the testis, which mimicked a testicular teratoma. A 42-year-old male presented with a left testicular swelling that had arisen suddenly and been present for three months. Scrotal ultrasound revealed a hypoechoic mass with several calcifications in the left testicle. The mass demonstrated blood flow in the color Doppler mode. A radical orchiectomy was performed. Pathological evaluation revealed a testicular cavernous hemangioma with thrombus organization and calcification.

[Testicular microlithiasis: report of 14 cases].  

Science.gov (United States)

Testicular microlithiasis (TM) is a comparatively rare condition in which calcified congelations fill the lumina of the seminiferous tubules. Using high-frequency linear transducers (10 MHz), TM is easily demonstrated as tiny punctate echogenic foci, which typically do not give an acoustic shadow, and is classified into classic type (CTM) and limited type (LTM) on the basis of the presence of five or more microliths at least on one image of the testes. Fourteen patients were found to have TM, 6 of which were LTM and 8 were CTM. In one patient with CTM, coexisting mixed germ cell tumor (seminoma, embryonal cell carcinoma) was demonstrated. Until further data are available, it seems reasonable to consider patients with TM as having an increased risk of developing a primary testicular tumor. PMID:14655598

Steroid receptor status of human testicular tumors.  

UK PubMed Central (United Kingdom)

Biopsies of 9 testicular tumors were examined for the presence of cytoplasmic receptor proteins for estrogens, progestins, androgens, and glucocorticoids. Using an arbitrary threshold value of 10 fmol/mg cytosol protein for a postive assay, only 1 of 9 tumors was estrogen-receptor positive. However, no receptor-specific 8S binding could be detected by low salt sucrose gradient centrifugation. 1 tumor was progesterone-receptor positive. No androgen receptors could be demonstrated. In contrast, 8 of 9 neoplasms contained significant quantities of glucocorticoid receptors exclusively sedimenting at 8S. Our findings suggest that androgens, estrogens, and progestins are unlikely to play a major role in the natural history of testicular tumors. The presence of glucocorticoid receptors might offer a chance for endocrine manipulation of the development and growth of these neoplasms by glucocorticoids.

Methamphetamine use can mimic testicular torsion.  

Science.gov (United States)

We report the case of a patient presenting with the classic clinical appearance of testicular torsion. Ultrasound showed testicular ischemia supporting the clinical diagnosis, but the lack of visualization of spermatic cord torsion was of concern. An attempt of clinical detorsion was considered unsuccessful and the patient was explored. No torsion was found. On postoperative review of the patient's medical history, we found methamphetamine use, with a positive urine test at the time of his emergent consultation for the scrotal pain episode. The use of amphetamines has been previously reported as the cause of ischemia of multiple organs, but we could not find previous reports of involvement of the testis mimicking torsion. PMID:23606543

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.)

Serum tumor markers in testicular cancer.  

UK PubMed Central (United Kingdom)

Testicular cancer has become a model for a curable neoplasm, where biochemical markers play a critical role. Serum tumor markers are integral in patient management and contributes to the diagnosis, staging, and risk assessment, as well as evaluation of response to therapy and detection of relapse. We review their biochemistry, biology, and clinical use in the setting of localized and metastatic disease. The integration of tumor markers in prognostic models as well as the significance of marker kinetics during chemotherapy is discussed.

The case of cavernous testicular hemangioma  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To present the rare case of testicular hemangioma. Case report: A 45-year-old clerk presented with painless swelling in the left testicle, which he noticed one month ago. Inguinal orchidectomy on the left side was performed and pathological report proved cavernous hemangioma. Conclusion: Hemangioma of the testis is very rare clinical condition. Clinical appearance and diagnostic exams are usually not sufficient for the diagnosis. Sometimes, hyperechoic lesion with increased vascularity can be seen on Doppler ultrasonography.

Relationship between Testicular Volume and Conventional or Nonconventional Sperm Parameters  

Science.gov (United States)

Background. Reduced testicular volume (TV) ( 15?cm3) and B Group, including 38 patients with reduced testicular volume (TV ? 12?cm3). All patients underwent serum hormone concentration, conventional and biofunctional (flow cytometry) sperm parameters evaluation. Results. With regard to biofunctional sperm parameters, all values (mitochondrial membrane potential, phosphatidylserine externalization, chromatin compactness, and DNA fragmentation) were strongly negatively correlated with testicular volume (P < 0.0001). Conclusions. This study for the first time in the literature states that the biofunctional sperm parameters worsen and with near linear correlation, with decreasing testicular volume.

Testicular masses in a man with a plausible sarcoidosis  

Science.gov (United States)

Genitourinary involvement with sarcoidosis is very rare. The objective of this report was to present a case of a patient with testicular swelling. The patient was an infertile 42-year-old man with bilateral testicular swelling. Semen analysis in the past 10 years revealed no abnormality; however, gradually he became azoospermic in 3 years. A diagnosis of sarcoidosis made on the basis of hilar and mediastinal lymphadenopathy in chest CT scan was confirmed through testicular and epididymal biopsy. Testicular masses vanished after administering steroids, and azoospermia recovered. To conclude, although genitourinary sarcoidosis is rare, it must be kept in mind in patients with confirmed sarcoidosis.

Doppler sonographic findings in testicular microlithiasis  

Directory of Open Access Journals (Sweden)

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

Quiste aracnoideo espinal epidural postraumático: presentación de un caso Postraumatic epidural arachnoid spinal cyst: case report  

Directory of Open Access Journals (Sweden)

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

[Escherichia coli meningitis in a 16-month old infant revealing a posterior fossa epidermoid cyst].  

UK PubMed Central (United Kingdom)

UNLABELLED: Meningitis due to Escherichia coli is rare, and generally observed in very particular circumstances, such as neonatal period, anatomical anomalies or in immune-deficient patients. CASE REPORT: A 16-month-old male infant was admitted for acute meningitis. E coli was detected in the cerebro-spinal fluid (CSF). As appropriate antibiotic treatment proved inefficient, a cerebral computerised tomography (CT) scan was performed, revealing an epidermoid cyst of the posterior fossa. The cyst was resected after CSF sterilisation. Postoperative recovery was satisfactory. CONCLUSION: When an unusual bacterial species such as E coli is detected in CSF, the authors suggest consideration of a cutaneous or ETN focus, or a congenital malformation with communication between cutaneous and meningeal structures.

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

International Nuclear Information System (INIS)

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

Unusual complications of a benign tumour - our experience with midline posterior fossa epidermoids.  

UK PubMed Central (United Kingdom)

Epidermoids of the brain are uncommon benign tumours. Their midline posterior fossa location is exceedingly rare. Fifteen patients with this condition were operated during a 14-year period. Majority of the patients presented in their middle age with mean duration of symptoms of 10 months. Gait imbalance was the commonest symptom observed. Seven patients had features suggestive of raised intracranial tension. Computed tomography scanning showed typical hypodense lesions. On MRI, tumours were hypo-intense on T1 weighted images and hyper-intense on T2 weighted images. All patients underwent microsurgical excision. We encountered certain complications in the post-operative period. This prompted us for a review of our case material and literature and is the basis of the present article. Implications of these findings are discussed.

Oral and maxillofacial myiasis associated with epidermoid carcinoma: a case report.  

UK PubMed Central (United Kingdom)

Myiasis is a term derived from the Greek word "myia", meaning invasion of vital tissue of humans or other mammals by fly larvae. The deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. It is an uncommon clinical condition, being more frequent in underdeveloped countries and hot climate regions, and is associated with poor hygiene, suppurative oral lesions, alcoholism and senility. Its diagnosis is made basically by the presence of larvae. This paper reports a case of oral and maxillofacial myiasis involving 273 larvae in a patient with epidermoid carcinoma without physical or neurological deficiency. The patient's management was antisepsis, larval removal and general care, before death after three months.

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

International Nuclear Information System (INIS)

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

Testicular microlithiasis: is it a benign condition with malignant potential?  

UK PubMed Central (United Kingdom)

OBJECTIVE: To review the findings of testicular ultrasonography (US) in patients referred for testicular symptoms including pain, swelling and infertility, and to determine the prevalence of testicular microlithiasis (TM) and ist relevance to the development of testicular cancer. METHODS: Records of 3,026 patients referred for testicular US between 1994 and 1999 were evaluated. The indications for testicular US diagnosis, management and relevant histological details were obtained from medical records. Patients with TM had an annual sonographic follow-up unless they had testicular cancer, in which case follow-up repeat US with clinical reviews was more frequent. RESULTS: TM was found in 54 patients (1.77%; median age 34 years, range 12-83 years). The median follow-up was 36 months (range 12-18 months). Sixteen of these patients had testicular malignancy (30%). The remaining 38 patients had hydrocele and epididymal cysts (14), varicocele (7), epididymitis (2) and small testes (8), with 14 patients having no other pathology. One patient with a small testis developed a seminoma while under surveillance. Another patient with metastatic embryonal-cell carcinoma at initial diagnosis was found to have a seminoma 4 years following chemotherapy. The relative risk of testicular tumours in the presence of TM was 13.2 (confidence interval 8.3-21.5). CONCLUSION: TM can no longer be regarded simply as a benign condition because of its association with testicular malignancy. In our series, 2 patients (5.2%) developed interval testicular cancers during follow-up US. There is no convincing evidence to suggest that TM might be premalignant. In rare instances of radiologically indeterminate cases, biopsy of the testis may be necessary.

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

Scientific Electronic Library Online (English)

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

The viability of the protoescolices were determined by the tincture with Trypan blue. 75% of the animals were from the south of Chile. In the 6 regions studied, around 16% of the bovines were positive to hydatidosis; 100% of the older animals (cows, bulls and oxen) and only 9.1 % of the younger animals were positive. 74% of the hydatid cysts were located in the lung, 25.6% in the liver and 0.4% in the spleen. With the age of the bovines increases the proportion of hepatic cysts. In the younger animals 67% of the cysts has less than 10 mm of diameter and all of them were infertile. In the older animals all cysts has more then 10 mm of diameter; 39.4% were fertile, 17.6% infertile and 43% altered. 82.7 % of the lung cysts and 15.8% of the hepatic cysts with more than 10 mm of diameter were fertile; 90.8% of them presented living protoscolices

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

Scientific Electronic Library Online (English)

Full Text Available Abstract in portuguese CONTEXTO: O câncer de pulmão de células não pequenas evolui, na maioria dos casos, com metástases a distância. Ossos, sistema nervoso central, glândula adrenal e fígado são os sítios mais frequentes de metástases. Disseminação para pele, miocárdio, tireoide e intestino pode ocorrer, entretanto é rara. RELATO DE CASO: Descrevemos um caso de carcinoma espinocelular (CEC) de pulmão com metástase em cólon e tireoide, em mulher de 66 anos. A lesão era irress (more) ecável, e foi iniciada quimioterapia. A paciente evoluiu com suboclusão intestinal e a colonoscopia evidenciou pólipo colônico cuja biópsia e imunoistoquímica (IHQ) foram compatíveis com CEC de origem pulmonar. Em consulta de acompanhamento, detectou-se nódulo tireoidiano cuja punção aspirativa e IHQ de cellblock confirmaram CEC de origem pulmonar. Após quimioterapia de terceira linha, a paciente evoluiu com abdome agudo obstrutivo por massa retroperitoneal, sendo submetida a laparotomia exploradora, vindo a falecer por complicações da cirurgia. Metástases para tireoide e cólon são raramente reportadas em carcinomas epidermoides de pulmão. O envolvimento gastrointestinal por metástases de pulmão pode acometer estômago, intestino delgado e cólon, e casos de sangramento e perfuração já foram reportados. Embora ricamente vascularizada, a tireoide é sítio infrequente de metástases. Os sítios refletem prognósticos reservados na evolução clínica. Não encontramos, na literatura, relato prévio de câncer de pulmão com metástases em cólon e tireoide concomitantes em um único paciente. Abstract in english CONTEXT: Non-small cell lung cancer (NSCLC) progresses to distant metastases in most cases. The most frequent sites for distant metastases are the bones, central nervous system, adrenal glands and liver. Dissemination to the skin, myocardium, thyroid gland and intestine may occur, but is rare. CASE REPORT: We describe a case of squamous cell carcinoma in the lungs, with metastases in the colon and thyroid, in a 66-year-old female patient. The lesion was unresectable and c (more) hemotherapy was started. The patient evolved with intestinal subocclusion, and colonoscopy showed the presence of a polyp. Biopsy and immunohistochemical analysis on the polyp showed that it was compatible with squamous cell carcinoma of pulmonary origin. At a follow-up consultation, the patient presented a thyroid nodule. A aspiration biopsy and cellblock immunohistochemistry confirmed the squamous cell carcinoma of pulmonary origin. After third-line chemotherapy, the patient progressed with acute obstructive abdomen due to a retroperitoneal mass. She underwent exploratory laparotomy and died due to surgical complications. Metastases to the thyroid and colon are rarely reported in cases of epidermoid carcinoma of the lungs. Gastrointestinal involvement in pulmonary metastases may affect the stomach, small intestine and colon, and cases of bleeding and perforation have already been reported. Although richly vascularized, the thyroid is an infrequent site for metastases. Such sites reflect poor prognoses for the clinical evolution. We did not find any previous reports in the literature, on lung cancer with metastases concomitantly in the colon and thyroid, in a single patient.

Spermatic vein phlebography in patients with testicular tumors.  

Science.gov (United States)

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

Efficacy of antioxidant treatment in the prevention of testicular atrophy in experimental testicular torsion.  

UK PubMed Central (United Kingdom)

BACKGROUND/PURPOSE: This study aimed to compare dose schedules of the antioxidant treatment (melatonin and steroid) used as 1 dose and as once a day for 7 days in terms of salvage of the testes in the late period. METHODS: Sixty prepubertal rats were divided into 6 groups each containing 10 rats: sham (S), torsion-detorsion (TD), 1-dose melatonin (M(1)), 1-dose steroid (ST(1)), 7-dose melatonin (M(7)), and 7-dose steroid (ST(7)) groups. The left testes were rotated 720 degrees for 6 hours and detorsed for 6 hours thereafter. In the treatment groups, 17 mg/kg melatonin and 1 mg/kg steroid were injected 15 minutes before detorsion. Left orchiectomies were performed to determine testicular weights and Johnsen scores 3 months later. RESULTS: Testicular weights and Johnsen scores in the M(1), ST(1), and TD groups were significantly lower compared with those in the S group, and atrophy developed in these groups, whereas they were higher in the M(7) and ST(7) groups compared with the TD group. Testicular atrophy did not develop in the M(7) or ST(7) groups. CONCLUSIONS: Our results suggested that antioxidant agents used once a day for 7 days prevent testicular atrophy and are effective in terms of salvage of the testes.

TESTICULAR CANCER – THE SUCCESS OF MULTIMODAL THERAPY  

Directory of Open Access Journals (Sweden)

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

Testicular hemangioma: a series of 8 cases.  

UK PubMed Central (United Kingdom)

Testicular hemangioma is a very rare neoplasm with only 25 cases reported in the English literature. We describe 8 cases of testicular hemangioma encountered at our institution between 1992 and 2012. Of the 7 consult cases, 4 were malignant, 1 a Leydig cell tumor, and 2 were recognized as hemangiomas. The patients' ages ranged from 9 to 54 years (mean 32; median 30). Seven patients presented with self-detected palpable masses, and 2 patients reported pain. Six hemangiomas involved the right testis, and 2 were left sided. Ultrasonography recognized hypervascularity in 3 cases. History of pelvic irradiation, chemotherapy, and remote scrotal trauma was present in 3 patients. Preoperative serum tumor markers were negative (2/2 cases). The average size was 1.7 cm (median 1.8; range, 0.5 to 3.0). Six cases were infiltrative within the testis and entrapped benign seminiferous tubules, and 3 tumors invaded the tunica albuginea. Three hemangiomas were epithelioid, 2 anastomosing, 1 cellular capillary, 1 capillary, and 1 cavernous. Mitoses were sparse in all but 1 case, which reached up to 5 per 10 HPF. In 6 cases, seminiferous tubules adjacent to the hemangioma were atrophic without spermatogenesis. Immunohistochemical analysis was performed in 6 cases, and tumors stained with CD31, CD34, FVIII-related protein, and FLI-1 but not with pancytokeratin AE1/3, epithelial membrane antigen, keratin 8/18, placental alkaline phosphatase, human herpes virus 8, human chorionic gonadotropin, c-kit, melan-A, or p53. In cases with follow-up, there were no recurrences in 7 patients (mean 21 mo; median 12 mo; range, 1 to 72 mo). In summary, testicular hemangioma is a rare neoplasm with different morphologies having in common an infiltrative growth pattern with entrapment of seminiferous tubules, which should not be considered a feature of malignancy. Clinical and radiologic findings may preoperatively suggest a vascular tumor.

Full Text Available Se presenta el caso de una mujer de 41 años que consulta por dolor abdominal y pelviano de carácter sordo de 6 semanas de evolución sin compromiso del estado general. Refiere el antecedente de una histerectomía por mioma realizada hace 3 años. La ecotomografía y la TAC de abdomen y pelvis revelan una lesión quística gigante de 15 x 8 x 12 cm que ocupa parte del abdomen y la pelvis. Luego de una resección parcial y marsupialización es referida a cirugía por recidiva precoz del tumor quístico. Es reintervenida, lográndose una extirpación completa más anexectomía bilateral con buena evolución posterior. El estudio histopatológico confirma el diagnóstico inicial de quiste mesotelial simple. La ubicación pelviana de la lesión, el comportamiento clínico (recidiva precoz con crecimiento rápido) y las dimensiones son más característicos de un mesotelioma quístico benigno. Sin embargo, el carácter unilocular permite catalogarlo como un quiste mesotelial de crecimiento excepcional. La distinción entre ambas entidades no es menor, toda vez que el mesotelioma quístico benigno tiene una recidiva alta y puede malignizarseWe report a 41 years old women presenting with abdominal and pelvic pain lasting six weeks. She had a history of hysterectomy three years ago. Abdominal ultrasound and CAT scan showed a giant cystic lesion of 15 x 8 x 12 cm that occupied a great portion of the abdomen and pelvis. After a partial resection and marsupialization, she was refereed to surgery due to an early relapse of the cyst. She was operated again, performing a complete cyst excision and bilateral anexectomy, with a good postoperative evolution. Pathology confirmed the diagnosis of a simple omental cyst. The unilocular feature of the lesion is characteristic of omental cysts. However, due to the pelvic location and dimensions, the differential diagnosis must be made with benign cystic mesothelioma, that had a high rate of relapse and may become malignant

[Testicular and epididymal appendages. Contribution about it's embryology and pathogenesis  

UK PubMed Central (United Kingdom)

OBJECTIVE: The testicular appendages are structures with biologic activity and with the possibility to become ischaemic or to degenerate before determined stimulus. Laterly, we have seen an apparent increase in our cases of torsion of testicular appendages. The said, together with the questions about embriology and pathogenesis of this structures, encourage us to do this work. PATIENTS AND METHODS: 1- Retrospective clinical study of patients operated of torsion of testicular appendages, from January 1984 to December 2001. We asses age, year of operation and clinical features. 2- Prospective clinical study of patients operated of torsion of testicular appendages, between March 1999 and March 2000. We asses age, time of evolution, degree of ischaemia, nutritional status, sexual maturity stage and testicular volume. 3- Inmunocytochemical study of testicular and epididymal appendages. We identified the oestrogen receptors. RESULTS: There is a meaningful increase in the yearly incidence of ischaemia of testicular appendages. The mean age of the patients was 9.3 +/- 2.5 years, similar alone of the study. In the patients of group 2, the mean time of evolution was 49.2 +/- 46.6 hours. The appendages showed oedema and several degrees of ischaemia in the absence of torsion (14/21). The body mass index was 19.5 +/- 3.7, and 90% of patients had stages I and II of Tanner. The mean of testicular volume was 2.1 +/- 1.6 ml. By means of inmunocytochemical study we identified oestrogen receptors in 7 of all testicular appendages studied and absence of oestrogen receptors in all epididymal appendages. CONCLUSIONS: The clinical syndrome of the acute scrotum in the majority of cases is due to oedema and ischemia of the appendages, in absence of torsion, probably related to its enlargement in response to hormonal stimulation, at least in some grade, in prepubertal boys. The difference found, related to oestrogen receptors, suggest a different origin for testicular and epididymal appendages.

Probability to retrieve testicular spermatozoa in azoospermic patients.  

UK PubMed Central (United Kingdom)

AIM: The degree of probability to retrieve spermatozoa from testicular tissue for intracytoplasmic sperm injection into oocytes is of interest for counselling of infertility patients. We investigated the relation of sperm retrieval to clinical data and histological pattern in testicular biopsies from azoospermic patients. METHODS: In 264 testicular biopsies from 142 azoospermic patients, the testicular tissue was shredded to separate the spermatozoa, histological semi-thin sections of which were then evaluated using Johnsen score. RESULTS: The retrieval of spermatozoa correlated significantly ( P < 0.001) with the testicular volume ( r = 0.49), the FSH concentration ( r = -0.66), the maximum score (r = 0.85) and the mean Johnsen score (r = 0.81). In the multivariate regression analysis the successful testicular sperm extraction showed the closest relationship to the maximum score. The testicular volume correlated significantly with the mean Johnsen score ( r = 0. 64, P < 0. 001), and the basal serum FSH concentration mainly with the maximum score ( r = - 0.77; P < 0.001). Patients with a history cryptorchidism showed a significantly lower Johnsen score compared to the patients who did not have any testicular disease in the past (3.7 +/- 2.4 vs. 5.9 +/- 2.5; P < 0. 01). CONCLUSION: In a limited range, the testicular volume and the FSH concentration in serum were related to the Johnsen score which correlated significantly with the sperm retrieval. The successful sperm retrieval can be expected in all azoospermic patients irrespective of the results of clinical examination. However, the probability of retrieval of spermatozoa decreased significantly in patients with a FSH level > 18 U/L, testicular volume < 5 mL, mean Johnsen score <5, and maximum Johnsen score <7.

Interest of the serous dosage of HER-2/neu, EGFr, VEGF, IL6 and Ac anti-P53 among patients damaged by an esophagus epidermoid carcinoma, type epidermoid carcinoma whom treatment was an exclusive chemoradiotherapy; Interet du dosage serique de HER-2/neu, EGFr, VEGF, IL6 et Ac anti-P53 chez des patients atteints d'un carcinome epidermoide de l'oesophage de type carcinome epidermoide dont le traitement etait une chimioradiotherapie exclusive  

Energy Technology Data Exchange (ETDEWEB)

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

Directory of Open Access Journals (Sweden)

Full Text Available Objetivo: El propósito de este estudio fue evaluar el marcador inmunohistoquímico p53 como factor pronóstico en pacientes que presentaban carcinoma epidermoide de lengua móvil en estadios I y II. Material y método: Se realizó un estudio retrospectivo de 36 pacientes (grupo homogéneo), correspondientes a un periodo de estudio de 10 años, comprendido entre los años 1985 y 1994. Las muestras procedieron de piezas quirúrgicas incluidas en bloques de parafina. Los estudios inmunohistoquímicos se han realizado aplicando la técnica inmunoperoxidásica, método ABC (complejo streptavidina-biotina-peroxidasa). Resultados y conclusiones: En la muestra homogénea estudiada, se apreció una relación significativa directa entre la inmunotinción positiva para p53 y la probabilidad de aparición de recidiva y/o muerte por enfermedad, así como una relación inversa entre la inmunotinción positiva para p53 y el tiempo medio de supervivencia en pacientes que presentaban carcinoma epidermoide de lengua móvil.Objetive: The purpose of this study was evaluating immunohistochemical marker p53 as a prognosis (diagnosis) factor in patients which presented mobile tongue epidermoid carcinoma in stages I and II. Material and method: A retrospective study was carried out to 36 patients (homogeneous group) corresponding to a study period of 10 years from 1985 to 1995. Samples came from surgical pieces included in paraffin blocks. Immunohistochemical studies were made by using immunoperoxidase technique method ABC (streptavidin-biotin- peroxidase complex). Results and conclusion: In the homogeneous sample case studied it a direct significant relation between positive immunotinción for p53 and the probability of reccurrence and/or death because of disease, as well as inverse relation between positive immunotinción for p53 and survival average time in patients which presented mobile tongue epidermoid carcinoma was observed.

Tu-M2-PK in the blood of testicular and cubital veins in men with testicular cancer.  

UK PubMed Central (United Kingdom)

We wanted to verity whether M2-PK is a useful marker in testicular cancer. In a prospective study of 20 consecutive patients, blood was drawn from the testicular and the cubital vein before semicastration and later. For the detection of M2-PK we used the Assay of ScheboTech. In the testicular vein M2-PK was 11.2 U/ml. In the cubital vein it was 6.2 U/ml before semicastration, increasing in the following days. There were no significant differences between testicular and cubital vein blood, between the non-metastasized patients and the metastasized stages and between the patients with seminoma and non-seminomatous tumors. There is no profit in the diagnosis of testicular cancer using Tu-M2-PK.

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

UK PubMed Central (United Kingdom)

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

Abstract in english PURPOSE: To evaluate the prevalence of testicular microlithiasis among pediatric patients with inguinoscrotal affections. METHODS: Between January 2005 and January 2010, we evaluated, prospectively 1504 children ranging from 1 to 15 years with inguinoscrotal affections with a high-frequency ultrasound system, which employs a 10-MHz transducer. RESULTS: Testicular microlithiasis was identified in 20 testes of eleven children (0.71% of 1504 patients evaluated), through an u (more) ltrasound scan. Testicular microlithiasis was found in 5 children with cryptorchidism (3.93% of 127 patients), 4 children with retractile testes (14.8% of 27 patients), 1 child with a hypotrophic testis (100% of 1 patient), and 1 child with inguinal hernia (0.07% of 1349 patients). The children with testicular microlithiasis were submitted to annual physical examinations and ultrasound evaluations. CONCLUSIONS: Testicular microlithiasis was a rare condition and occurred in 0.7% of the subjects studied. The association with cryptorchidism, retractile and hypotrophic testis was significant.

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

Scientific Electronic Library Online (English)

Full Text Available Abstract in spanish RESUMEN De acuerdo a numerosos autores el tratamiento para el quiste dentígero ha sido la eliminación total del quiste incluyendo el diente involucrado aunque si la lesión se presenta en pacientes jóvenes que están en período de erupción dentaria y las características clínicas y radiográficas sugieren la presencia de un quiste dentígero, existe una alternativa de tratamiento la cual es la de mantener el diente permanente no erupcionado y enuclear completamente (more) la lesión, siempre que se obtenga el diagnóstico definitivo histopatológico confirmatorio de quiste dentígero. Se realizó un estudio clínico en 12 pacientes de 7 a 16 años de edad con un promedio de 9,4 años, quienes fueron tratados en el Postgrado de Cirugía Bucal de la Facultad de Odontología de la Universidad Central de Venezuela (UCV). Todos los pacientes tenían las características clínicas y radiográficas similares a las del quiste dentígero, se encontraron 5 mujeres y 7 hombres, los cuales fueron sometidos a biopsia excisional, donde se les eliminó la lesión por completo, dejándoles el diente permanente no erupcionado. Las lesiones eran en la mandíbula y las imágenes radiolúcidas eran bien delimitadas al cuello dentario y menores a 2,5 cms. de diámetro. Los pacientes con quiste dentígero asociado a un tercer molar fueron excluídos del estudio. El estudio histopatológico fue confirmatorio de quiste dentígero para cada paciente y a cada uno se les realizó un seguimiento clínico y radiográfico periódico desde 2 meses hasta 7 años, con un intervalo aproximado de cada 6 meses. (1999-2006). No se encontraron imágenes radiolúcidas en ninguna de las radiografías post-quirúrgicas. Todos mostraron nueva formación ósea alrededor del diente involucrado y erupción completa de la dentición permanente. Tres(3) pacientes fueron seguidos por 7 años, cuatro(4) por 5 años, dos(2) por 3 años con 9 meses y tres(3) por 2 años y 6 meses. A dos(2) de los pacientes se les realizó tratamiento ortodóncico para corregir su maloclusión. Preservar el diente involucrado en un Quiste
