Abstract: two types primary epithelial tumours of the kidney have been distinguished, such as renal cell carcinoma (hypernephroma or grawitz) deriving from proximal tubules and carcinoma arising in the urothelium of the kidney's collecting system. mancilla-jimenez e cols were the first to describe in 1976 an atypical papillary carcinoma of the kidney deriving from collecting duct system-bellini duct carcinoma (bdc). in the world healthy organization classification it is listed as a rare carcinoma ( 1 % of the renal malignancies) originating in the renal medulla. histologic examination shows both tubular and papillary architeture, which can lead to misinterpretation as renal cell or transitional cell carcinoma. renal cell carcinoma originates from the metanephrogenic blastema and collecting duct carcinoma derived embryologicaly from the mesonephron wolff duct. renal cell carcinoma has been shown to express both cytokeratins and vimetin, whereas the distal convoluted tubule expresses only cytokeratins. bdc can be considered as a renal malignancy with a very bad prognosis compared to the other renal cell carcinoma. the best treatment is radical nephrectomy. a case of bdc is reported in a young black man, 27 year old with only history of light left back pain. ultrasound and other image examinations showed a tumour about 6 cm in the middle and low left kidney. patient was submitted to extraperitoneal radical nephectomy. microscopic evaluation revealed kidney's collecting duct carcinoma with metastasis on two retroperitoneal lymphy nodes.

Abstract: La aparición de metástasis de un carcinoma renal a nivel parotídeo es un fenómeno poco frecuente. En la literatura indexada, solo se han descrito 29 pacientes desde 1986. Presentamos un paciente de 61 a os, que tras cinco a os de la realización de una nefrectomía unilateral por un carcinoma renal de células claras, desarrolló una metástasis de localización parotídea. Metastastic spread of renal cell carcinoma to the parotid gland is rare. In the indexed literature, with only 29 patients recorded since 1986. The case of a 61-year-old patient who developed parotid metastasis of renal cell carcinoma five years after unilateral nephrectomy is reported.

Abstract: El carcinoma renal de células claras es el tipo histológico más frecuente. En el momento del diagnóstico, las metástasis están presentes en 25-30 % de los pacientes aproximadamente. La peculiar tendencia de dicho carcinoma a metastizar en localizaciones poco usuales, hace de este proceso oncológico un tumor primario a tener en cuenta en el diagnóstico diferencial de las metástasis como primera manifestación de neoplasia. Se presenta un caso poco frecuente, con tumor en fosa nasal izquierda y epistaxis recidivante, secundaria a metástasis de carcinoma renal como primer síntoma. The renal carcinoma of clear cells is the most frequent histological type. Metastasis is present in approximately 25-30 % of the patients in the diagnosis. The peculiar tendency of this carcinoma to make metastasis in not very usual areas, makes of this oncological process a primary tumour to keep in mind in the differential diagnosis of metastases as the first neoplasia manifestation. A not very frequent case is presented, with tumour in the left nasal cavity and recurrent epistaxis, secondary to metastasis of renal carcinoma as first symptom.

Abstract: La presencia de carcinoma de células renales durante la evolución de una enfermedad poliquística renal autosómica dominante es muy rara y poco reportada en la literatura internacional. Se reporta un caso de enfermedad poliquística renal asociado con carcinoma de células renales. La forma de presentación fue un síndrome febril prolongado, pérdida de peso, eritrosedimentación acelerada y aumento de volumen de una imagen compleja en el ri ón izquierdo que duplicó su tama o en un mes. En el acto quirúrgico se comprobó presencia de ganglios parahiliares renales y paraaórticos infiltrados; en el estudio patológico macroscópico, infiltración de la vena renal, y en el microscópico, presencia de tejido neoplásico en el parénquima renal. The presence of renal cell carcinoma during the evolution of an autosomal dominant polycystic kidney disease is very rare and little reported in international literature. It is reported a case of polycystic renal disease associated with renal cell carcinoma . The form of presentation was a prolonged febrile syndrome, weight loss, accelerated erythrosedimentation and volume increase of a complex image in the left kidney that dobled its size in a month. During surgery, it was proved the presence of infiltrated renal parahilar and paraaortic ganglia. In the macroscopic pathological study, it was observed infiltration of the renal vein; whereas, in the microscopic study, it was reported the presence of neoplastic tissue in the renal parenchyma.

Abstract: A pesar de ser la ectopia renal una anomalía usual y el carcinoma de células claras la neoplasia renal más frecuente, existen muy escasos reportes de presentación simultánea de ambas condiciones. Se notificó una paciente, con estas características, que fue tratada quirúrgicamente y mantuvo una evolución satisfactoria. In spite of the fact that the renal ectopy is a common anomaly and the clear cell carcinoma is the more frequent renal neoplasm, there are not many reports on a simultaneous presentation of both conditions. There was the case of a female patient presenting these features and that was operated on with a satisfactory course.

Abstract: Presentamos el caso de un varón de 69 a os sin patología previa de interés que presentó clínica de pérdida de fuerza distal en miembros inferiores de dos meses de evolución. La resonancia magnética (RM) mostró la presencia de una masa intramedular a nivel del cono. El paciente fue intervenido practicándose resección de la tumoración, mostrando el estudio histológico la presencia de un carcinoma de células claras correspondiente a una sospecha de metástasis de un tumor renal, que posteriormente se confirmó con una tomografía axial computarizada (TAC) abdominal. Cuando el estado del paciente es bueno, la cirugía puede subsanar el déficit neurológico producido por la lesión intramedular. Nuestro paciente, tras la intervención, mejoró su estado neurológico; y actualmente, tras 14 meses, se mantiene sin déficit neurológico en miembros inferiores. We present the case of a 69 year-old male without known antecedente who presented a clinical loss of distal force in his lower limbs during the last two months. Magnetic resonance imaging (MRI) showed an intramedullary spinal cord mass at the level of the medullaris cone. The patient was operated on; the histological diagnosis was clear cells carcinoma suggestive of metastasis from an unsuspected renal tumor that was later confirmed with an abdominal CT. When the patient's state is good, surgery can correct the neurological deficit produced by an intramedullary spinal cord lesion. The neurological state of our patient impro-ved after the intervention, and 14 months after surgery, he has no neurological deficit in the lower limbs.

Abstract: Cerebral extra-axial metastasis mimicking meningioma which satisfy several criteria for a diagnosis of meningioma, but which have proved instead to be metastatic carcinoma and extremely delayed cerebral metastasis from renal cell carcinoma form the focus of the presentation. 68-year-old-woman who had been operated for renal cell carcinoma 20 years previously is presented with new symptoms of intracranial mass. A large extraaxial mass of the convexity which destroyed calvarium and dura was excised with Simpson Grade I removal, revealed metastatic carcinoma. Imaging characteristics can not always discern between meningioma and metastatic tumours. A meticulous clinical evaluation and histopathological diagnosis is essential in patients with intracranial mass even they resemble both primary and metastatic tumours. Se presenta un caso de metástasis craneal extra-axial, que satisface varios criterios para el diagnóstico de meningioma, en el cual se demostró que se trataba de la metástasis tardía de un carcinoma renal. Una paciente de 61 a os, que había sido operada de un carcinoma renal 20 a os antes, se presentó con síntomas de un tumor cerebral. Se extirpó un gran tumor extra-axial de la convexidad, que destruía la bóveda craneal y la duramadre, (Simpson grado I), pero que reveló se trataba de una metástasis. Las imágenes de estas característica no siempre pueden discernir entre un meningioma y una metástasis. Es esencial realizar una meticulosa valoración clínica y un diagnóstico histopatológico en pacientes con tumores intracraneales, aunque parezcan tumores metastáticos.

Abstract: metástasis to the breast from extramammary solid neoplasms is a very unusual condition. it must be clearly distinguished from primary carcinoma of the gland because of its different treatment and prognosis. metastasis from renal carcinoma to the breast is even more rare. we herein report a case of a 57 years old woman, with a metastasis to the breast of a previously treated clear cell renal carcinoma.
