RESUMEN

OBJECTIVES: To report a new case of late renal cell carcinoma recurrence. METHODS: Renal cell carcinoma represents approximately 3% of all adult malignancies. The most frequent metastatic sites are lung (76%), regional lymph nodes (66%), bone (42%), and liver (41%), and it is the third most common infraclavicular neoplasm to metastasize to head and neck. RESULTS: 73 year-old man with a 1 week history of recurrent epistaxis. He underwent left nephrectomy 17 years before due to a renal mass of 8.5 cm in the upper pole of the left kidney. The histological diagnosis of the referred mass was clear cell carcinoma. No metastatic lesion was found at that time (Stage I, pT2N0M0). CT scan showed a mass in the right nasal cavity, invading the right ethmoidal sinus and the right orbit. Examination under general anaesthesia and biopsy was performed revealing metastasis of a renal cell carcinoma. CONCLUSIONS: The natural history of renal cell carcinoma is highly variable, metastases may present decades after the removal of the primary disease, however, only 1% of patients with renal cell carcinoma have metastases confined only to the head and neck, and solitary cervical metastatic mass is rare. Moreover, renal cell carcinoma should be considered in the differential diagnosis of any growing lesion in the head and neck.

RESUMEN

OBJETIVOS: Presentar un nuevo caso de recidiva tardía de un carcinoma de células renales.MÉTODOS: Los carcinomas renales suponen el 3% de todos los tumores en el adulto. Los lugares más frecuentes de afectación metastático son el pulmón (76%), ganglios linfáticos regionales (66%), hueso (42%) e hígado (41%), y además, es la tercera neoplasia infraclavicular en frecuencia en metastatizar en cabeza y cuello RESULTADOS: Varón de 73 años que consulta por episodio de epistaxis de 1 semana de evolución. El paciente había sido sometido a una nefrectomía izquierda por una masa de 8,5 cm en polo superior renal 17 años antes. El informe anatomo patológico fue de carcinoma renal de células claras. No se evidenciaron metástasis en los estudios de extensión previos a la cirugía (Estadio I, pT2N0M0). En el nuevo ingreso se realizó un escaner que mostró una masa en la cavidad nasal derecha que invadía en el seno etmoidal y la órbita derecha. Se llevó a cabo una exploración bajo anestesia con toma de biopsia confirmando la histología de carcinoma renal de células claras.CONCLUSIONES: La historia natural del cáncer renal es muy variable, pudiendo aparecer metástasis décadas después de la nefrectomía inicial, si bien sólo el 1% de estos pacientes presentan metástasis confinadas solamente a la cabeza y cuello. El carcinoma de células renales debe ser considerado en el diagnóstico diferencial de cualquier masa en cabeza y cuello(AU)

RESUMEN

OBJECTIVES: The objective of our study was to evaluate patient tolerance to transrectal ultrasound guided prostate biopsy using anesthesia with 2 grams of intrarectal lidocaine gel, and to evaluate the complications of the test. METHODS: 148 prostate biopsies with intrarectal lidocaine were performed over a four month period. The same intrarectal ultrasound transducer and needle mechanism were employed for all patients. Biopsies were performed by 7 different urologists with 6 to 12 cores per biopsy. All patients received after the biopsy a questionnaire to evaluate their tolerance to the intervention. In the same way, the urologist performing the biopsy filled a questionnaire about patient tolerance and complications of the test. RESULTS: Patient tolerance data were recorded in 147 biopsies. Twenty-five cases (16.9%) referred severe or unbearable pain, 45 patients (13.4%) referred no pain at all. A significant association between patients' and doctors' results was obtained. Digital rectal examination was painful in 10 cases only; transducer insertion was painful in 13, and 15 referred pain with the transducer movements inside the rectum. Almost all painful or unbearable core biopsies were taken in the apex. There was a significant association (p = 0.005) between the number of cores per biopsy and pain, being the pain more than expected when the number of cores was greater than six. Only 14 patients would not ever repeat the same biopsy or would request a different type of anesthesia and 133 (59.9%) of them would repeat it in the same way. CONCLUSIONS: In our experience, transrectal ultrasound guided prostatic biopsy is generally well tolerated with intrarectal gel as the only anesthesia. Nevertheless, the number of cores taken per biopsy has been the factor associated with pain, and if the number of biopsy cores increases additional anesthesia should be considered.

RESUMEN

OBJECTIVES: To review the influence of various intravesical treatments on superficial bladder cancer progression. METHODS: We retrospectively reviewed 473 superficial bladder neoplasias. Based on diagnosis and transurethral resection of bladder tumor (TUR BT), and depending on pathology, we proposed different treatment and follow-up schemes, with BCG in 139 cases and intravesical chemotherapy, mainly Mytomicin C, in 80. RESULTS: Overall, the use or not of bladder instillations did not show statistically significant differences in time to progression. The use of intravesical therapy and maintenance therapy was an independent risk factor for disease-free time to progression when compared with induction. CONCLUSIONS: The use of maintenance intravesical therapy with BCG resulted in a delayed progression of superficial bladder cancer, so that it seems the most effective treatment, mainly in moderate-high risk tumors.

RESUMEN

Objetivo: El objetivo de nuestro estudio, fue valorar la tolerancia por parte del paciente a una biopsia de próstata transrectal ecodirigida usando como método anestésico un gel con 2 gramos de lidocaina intrarectal, así como valorar las complicaciones de esta prueba. Método: Durante 4 meses consecutivos se realizaron 148 biopsias de próstata ecodirigidas usando 2 gramos de lidocaina intrarectal. Se usó el mismo transductor ecográfico transrectal en todos los pacientes, usándose también el mismo mecanismo de aguja para la obtención de los cilindros. Las biopsias fueron realizadas por 7 urólogos diferentes obteniéndose en cada biopsia entre 6 y 12 cilindros. A todos los pacientes se les entregó tras la prueba un cuestionario para valorar la tolerancia a este método. Así mismo, el médico que realizó las biopsias rellenaba un cuestionario a cerca del paciente en el que valoraba la tolerancia del paciente y las complicaciones tras la prueba. Resultados: Se recogieron los datos de tolerancia en 147 casos, existiendo dolor intenso o insoportable globalmente en 25 casos (16,9 %) y nada molesto en 45 pacientes (30,4 %). Se evidenció una asociación significativa entre el resultado del cuestionario del paciente y la percepción del médico que realizó la prueba. Sólo en 10 casos el tacto rectal fue doloroso, en 13 el paso del transductor y en 15 los movimientos del mismo en el recto. Prácticamente todos los cilindros que resultaron dolorosos o insoportables en la toma de muestras fueron los recogidos de la zona del ápex. Se encontró una asociación significativa (p=0,005) entre el número de cilindros y el dolor durante la obtención de los mismos, siendo mayor de lo esperado el dolor cuando se realizaron biopsias por encima de las sextantes. Sólo 14 pacientes no realizarían nuevamente la misma prueba o requerirían otro tipo de anestesia y el 89,9 % (133), volverían a realizarla en las mismas condiciones. Conclusiones: En nuestra experiencia la biopsia prostática ecodirigida es generalmente bien tolerada empleando únicamente un gel anestésico intrarectal. No obstante, el número de punciones durante la biopsia ha sido el factor asociado al dolor de la prueba y al incrementarse aquel debería plantearse el empleo de algún tipo adicional de anestesia (AU)

RESUMEN

OBJETIVOS: Revisar la influencia de distintos tratamientos endovesicales sobre la progresión del cáncer vesical superficial. METODOS: Se revisaron retrospectivamente un total de 473 neoplasias vesicales superficiales. A partir del diagnóstico y la RTU vesical, y en función del resultado anatomopatológico, se plantearon distintos esquemas de seguimiento y tratamiento complementario, se empleó BCG en 139 casos y quimioterapia endovesical en 80 pacientes fundamentalmente Mitomicina C (MMC). RESULTADOS: Globalmente, el empleo o no de instilaciones vesicales no mostró diferencias estadísticamente significativas en cuanto al tiempo de progresión Resultó factor independiente para explicar un menor tiempo libre hasta la progresión el empleo de terapia endovesical con terapia de mantenimiento frente a inducción. CONCLUSIONES: La utilización de terapia endovesical de mantenimiento con BCG implicó una progresión más tardía del cáncer vesical superficial, por lo que parece el tratamiento más eficaz, sobretodo en tumores de moderado y alto riesgo (AU)

RESUMEN

OBJECTIVES: Syphilis is a systemic disease the course of which follows successive clinical stages. Central nervous system and spinal cord involvement on late phases may lead to bladder dysfunction. We report one case of neurosyphilis with associated bladder hyperreflexia. METHODS/RESULTS: 51-year-old male with the diagnosis of neurosyphilis consulting for voiding disorders with evidence of detrusor hyperactivity of neurogenic etiology on the urodynamic study. CONCLUSIONS: The differential diagnosis of neurogenic bladder in patients with psychiatric or neurological symptoms should include neurosyphilis. Etiologic diagnosis is obtained by cerebrospinal fluid examination, and the diagnosis of bladder dysfunction by urodynamic study.

RESUMEN

OBJECTIVES: To report a rare clinical case of solitary pararenal fibrous tumor, analyzing its pathological characteristics and prognosis by a bibliographic review. METHODS/RESULTS: We present the case of a 36-year-old male consulting for right flank colic pain, which was diagnosed of a solid mass in the lower pole of the right kidney and underwent right radical nephrectomy. Pathological study of the surgical specimen showed the presence of a solitary pararenal fibrous tumor. CONCLUSIONS: Solitary fibrous tumor is a rare neoplasia, being its pararenal localization even rarer. It is a tumor with benign behavior in up to 90% of the cases. The immunohistochemical study is the key to diagnosis.

RESUMEN

OBJECTIVE: To report a rare case of a giant epidermoid cyst in an intertesticular localization, analyzing its histological and pathologic features, and to perform a bibliographic review. METHODS/RESULTS: We report the case of a 49-year-old male consulting for a slowly growing intra-scrotal mass of five years of evolution causing discomfort because of its size. After excision the pathology report showed the presence of a keratoid epidermoid cyst very big in size. CONCLUSIONS: Superficial scrotal epidermoid cysts are frequent in clinical practice; that is not the case of the so-called "intra scrotal inclusion cysts". Epidermoid cysts are firm, mobile, slowly growing, generally asymptomatic intra epidermal neoformations. There are descriptions in multiple sites, even the genitalia, nevertheless their size in this location does not usually pass 5 cm.

RESUMEN

OBJETIVO: Añadir a la literatura un caso clínico poco frecuente de quiste epidermoide gigante de localización intertesticular, analizando las características histológicas y patológicas del mismo y realizando una revisión de la literatura al respecto. MÉTODOS/RESULTADOS: Presentamos el caso de un varón de 49 años que consultó por bultoma intraescrotal de 5 años de evolución y lento crecimiento que le ocasionaba molestias por su gran tamaño. Tras exéresis del mismo, el resultado anatomopatológico de la muestra evidenció la presencia de un quiste epidermoide queratinoso de gran tamaño. CONCLUSIONES: Los quistes epidérmicos escrotales superficiales son de frecuente aparición en la práctica clínica, no así los denominados “de inclusión” intraescrotales. Los Quistes Epidermoides son neoformaciones intraepidérmicas, firmes y móviles de crecimiento lento y habitualmente asintomáticos. Están descritos en múltiples localizaciones, incluso en genitales, sin embargo el tamaño de estos a este nivel no suele superar los 5 cm
