ABSTRACT
La hipertensión arterial (HTA) grave en pediatría responde fundamentalmente a causas secundarias. Presentamos una paciente adolescente de 14 años con HTA grave, alcalosis metabólica e hipopotasemia, secundaria a un tumor de células yuxtaglomerulares productor de renina, diagnosticado luego de dos años de evolución de HTA.
Severe arterial hypertension (HTN) in pediatrics is mainly due to secondary causes. Here we describe the case of a 14-year-old female adolescent with severe HTN, metabolic alkalosis, and hypokalemia, secondary to a renin-secreting juxtaglomerular cell tumor diagnosed after 2 years of HTN progression.

OBJECTIVE@#To investigate the incidence and potential influence factors that contribute to chronic post-surgical pain (CPSP) in elderly patients with urinary tract tumors who underwent laparoscopic procedures.@*METHODS@#A retrospective study was conducted to collect the clinical data of 182 elderly patients with urinary tract tumors who were ≥65 years and underwent laparoscopic surgery from October 2021 to March 2022 in Peking University Third Hospital. The patients'demographic information, medical history and the severity of postoperative pain were collected. Telephone follow-ups were made 6 months after surgery, and the patients' CPSP conditions were recorded. The diagnostic criteria of CPSP were referred to the definition made by the International Association for the Study of Pain (IASP): (1) Pain that developed or increased in intensity after surgical procedure and persisted for at least 3 months after surgery; (2) Pain that localized to the surgical field or projected to the innervation territory of a nerve situated around the surgical area; (3) Pain due to pre-existing pain conditions or infections and malignancy was excluded. The patients were divided into two groups based on CPSP diagnosis. Risk factors that predisposed the patients to CPSP were identified using univariate analysis. A multivariate Logistic regression model using back-forward method was designed, including both variables that significantly associated with CPSP in the univariate analysis (P < 0.1), and the variables that were considered to have significant clinical impact on the outcome.@*RESULTS@#Two hundred and sixteen patients with urinary tract tumors who had undergone laparoscopic surgery were included, of whom, 34 (15.7%) were excluded from the study. For the remaining 182 patients, the average age was (72.6±5.2) years, with 146 males and 36 females. The incidence of CPSP at the end of 6 months was 31.9% (58/182). Multiva-riate regression analysis revealed that age ≥75 years (OR=0.29, 95% CI: 0.12-0.73, P=0.008) was the protecting factors for postoperative chronic pain in the elderly patients with urinary tract tumors undergoing surgical treatment, while renal cancer (compared with other types of urinary tract tumors) (OR=3.68, 95% CI: 1.58-8.58, P=0.003), and the 24 h postoperative moderate to severe pain (OR=2.57, 95% CI: 1.14-5.83, P=0.024) were the independent risk factors affecting CPSP.@*CONCLUSION@#Age < 75 years, renal cancer and the 24 h postoperative moderate to severe pain are influence factors of the occurrence of CPSP after laparoscopic surgery in elderly patients with urinary tract tumors. Optimum postoperative multimodal analgesia strategies are suggested to prevent the occurrence of CPSP.

OBJECTIVES@#To study the correlation between 25-hydroxyvitamin D [25-(OH)D] and nephroblastoma in children and its value in assessing the prognosis of the disease.@*METHODS@#A total of 50 children with nephroblastoma who were admitted from January 2018 to December 2022 were included as the nephroblastoma group, and according to the postoperative pathological type, they were divided into a good prognosis group with 38 children and a poor prognosis group with 12 children. A total of 50 healthy children who underwent physical examination during the same period of time served as the healthy control group. The above groups were compared in terms of serum creatinine and 25-(OH)D level. A Spearman correlation analysis was used to investigate the correlation between serum 25-(OH)D level and therapeutic effect reaction. A multivariate logistic regression analysis was used to identify the risk factors affecting the prognosis of nephroblastoma in children.@*RESULTS@#The nephroblastoma group had significantly lower levels of serum creatinine and 25-(OH)D than the healthy control group (P<0.05). Compared with the good prognosis group, the poor prognosis group had a significantly larger tumor diameter, a significantly higher proportion of children with stage III-IV tumors, a significantly higher rate of tumor metastasis, and significantly lower serum levels of creatinine and 25-(OH)D (P<0.05). The Spearman correlation analysis showed that serum 25-(OH)D level was negatively correlated with therapeutic effect reaction (rs=-0.685, P<0.001). The multivariate logistic regression analysis showed that tumor diameter ≥10 cm, stage III-IV tumors, presence of tumor metastasis, and 25-(OH)D <19 ng/mL were closely associated with the poor prognosis of nephroblastoma in children (P<0.05). Serum 25-(OH)D level had an area under the curve of 0.805 (95%CI: 0.706-0.903, P<0.001) in evaluating the prognosis of nephroblastoma in children, with a Youden index of 0.512, a sensitivity of 0.938, and a specificity of 0.575 at the optimal cut-off value of 1.764 ng/mL.@*CONCLUSIONS@#There is a significant correlation between 25-(OH)D level and the prognosis of nephroblastoma in children, and 25-(OH)D can be used for prognosis prediction.

Resumen El presente articulo describe un caso clínico de una paciente con un ''trombo tumoral''. Estos son tumores que se extienden desde el órgano afectado hasta el atrio derecho, por la vena cava inferior. Hasta el 10 % de los tumores descritos pueden alcanzar la vena cava inferior y el 1 % de estos llegan a atrio derecho. El carcinoma de células renales es el más frecuente en producir este cuadro. El objetivo del articulo es mostrar que es fundamental realizar un adecuado diagnóstico diferencial, ya que existen diferentes procesos tumorales que pueden causar un ''trombo tumoral'' y diferentes causas de masas en el atrio derecho. La clínica de los pacientes con este cuadro será por obstrucción de la vena cava. El diagnóstico se realiza con estudios de imágenes, ultrasonido (US), ecocardiograma, tomografía axial computarizada (TAC) y resonancia magnética. El manejo debe de ser quirúrgico, sin embargo, presenta pronóstico desfavorable, en algunos casos se puede resecar el tumor primario y extraer la masa que ha invadido la vena cava inferior.
Abstract: This article describes a clinical case of a patient with a 'tumoral thrombus''. These are tumors that extend from the affected organ to the right atrium, through the inferior vena cava. Up to 10% of the tumors described can reach the inferior vena cava and 1% of these reach the right atrium. Renal cell carcinoma is the most common to produce this condition. The objective of the article is to show that it is essential to carry out an adequate differential diagnosis since there are different tumor processes that can cause a ''tumoral thrombus'' and different causes of masses in the right atrium. The symptoms of patients with this condition will be caused by the obstruction of the vena cava. The diagnosis is made with imaging studies, ultrasound (US), echocardiography, computerized axial tomography (CT) and magnetic resonance imaging. The management must be surgical, however it has an unfavorable prognosis, in some cases the primary tumor can be resected and the mass that has invaded the inferior vena cava removed.

ABSTRACT Sarcopenia, a concept reflecting the loss of skeletal muscle mass, was reported to be associated with the prognosis of several tumors. However, the prognostic value of sarcopenia in patients with renal cancer remains unclear. We carried out this metaanalysis and systematic review to evaluate the prognostic value of sarcopenia in patients with renal cell carcinomas. We comprehensively searched PubMed, Embase, and Cochrane Library from inception to December 2018. Hazard ratio (HR) and 95% confidence interval (CI) were pooled together. A total of 5 studies consisting of 771 patients were enrolled in this quantitative analysis, 347 (45.0%) of which had sarcopenia. Patients with sarcopenia had a worse OS compared with those without sarcopenia (HR=1.76; 95%CI, 1.35-2.31; P <0.001). In the subgroup of patients with localized and advanced/metastatic diseases, sarcopenia was also associated with poor OS (HR=1.48, P=0.039; HR=2.14, P <0.001; respectively). With a limited sample size, we did not observe difference of PFS between two groups (HR=1.56, 95% CI, 0.69-3.50, P=0.282). In the present meta-analysis, we observed that patients with sarcopenia had a worse OS compared with those without sarcopenia in RCC. Larger, preferably prospective studies, are needed to confirm and update our findings.

Objective To report a case of intradural extramedullary metastasis originated from a kidney neoplasm. Metastases in this topography occur in a low frequency, especially considering that the primary tumor was located along the urinary system. Case Report Amale adult begins to present with pain in the lower limbs and develops flaccid paraparesis of the pelvic limbs, also attacking the control of the sphincter. The patient had a previous history of right nephrectomy due to a kidney neoplasm. After investigation with imaging exams, ametastatic lesion was found to be the source of the symptoms. The patient was surgically treated by the neurosurgery team of the hospital. Conclusion Cases like this are not common, and considering the low incidence of these cases and the nonspecific symptoms, such as pain, we do not always come up with the hypothesis of a metastasis in this topography. The surgical treatment, although it is a palliative feature, has an important part inmaintaining the performance and the quality of life of the patient.

Introducción: Existen pocas investigaciones sobre factores de riesgo de tumores renales pediátricos. Objetivo: Caracterizar en detalle regiones geográficas de alta incidencia de tumores renales pediátricos en el centro de Argentina y su posible vinculación con factores de riesgo genéticos. Métodos: El área de estudio comprendió la provincia de Córdoba (Argentina). Se generó una base de datos de incidencia del cáncer renal infantil con información del Registro Provincial de Tumores. Se realizaron análisis de conglomerados espaciotemporales. En localidades dentro de los conglomerados, se llevaron a cabo entrevistas en profundidad a informantes claves. Resultados: Se registraron 56 casos de tumores renales pediátricos en el Registro en el periodo 2004-2013. Se detectó un conglomerado espacial significativo que abarca siete departamentos de la provincia. En esa región se concretaron seis entrevistas en profundidad a informantes claves. Los entrevistados resaltaron la mayor frecuencia de enfermedad genética de Sandhoff y las prácticas de endogamia (corroboradas en numerosos resultados científicos). A partir de estos datos se determinaron zonas de superposición de tumores renales y de la enfermedad de Sandhoff. Conclusiones: Se detectó una región particular de la provincia con alta frecuencia de tumores renales pediátricos y de la enfermedad de Sandhoff. Numerosos estudios científicos determinan que la endogamia es el factor de riesgo que aumenta la frecuencia de esta enfermedad en esta región. En futuras investigaciones se deberá corroborar si la endogamia también actúa aumentando la incidencia de tumores renales infantiles(AU)
Introduction: There is little research on risk factors of pediatric renal tumors. Objective: To characterize in detail the geographic regions of greatest incidence of pediatric renal tumors in central Argentina and exploring their possible link to genetic risk factors. Methods: The study area comprised the province of Córdoba (Argentina), and a database of pediatric renal tumors incidence was generated with information from the Provincial Tumor Registry. Analyses of spatio-temporal clusters were performed. In-depth interviews with key informants were carried out at localities within the conglomerates. Results: 56 cases of pediatric renal tumors were registered in the Provincial Registry of Tumors between 2004 and 2013. A significant spatial conglomerate was detected, covering seven districts of the province. In that region, six in-depth interviews were conducted with key informants. Interviewees highlighted the increased frequency of Sandhoff genetic disease and endogamous practices (corroborated in numerous scientific results). From these data, zones of overlap of renal tumors and of Sandhoff disease were determined. Conclusions: A particular region of the province was detected with high frequency of pediatric renal tumors and Sandhoff disease. Numerous scientific studies have determined that endogamy is the risk factor that increases the frequency of Sandhoff disease in this region. In future research, it should be confirmed whether it also acts by increasing the incidence of renal tumors in children(AU)

El ligamento falciforme es una reflexión peritoneal abdominal relacionada con la superficie anterior del hígado, que en su borde inferior libre contiene el ligamento redondo (LR); las lesiones únicas en este son infrecuentes. Presentamos un caso de metástasis única en el ligamento redondo en un paciente con antecedente de carcinoma renal de células claras. Realizamos una búsqueda bibliográfica para identificar casos similares. Nuestro paciente es un varón de 71 años con antecedente de carcinoma renal de células tratado con nefrectomía radical izquierda laparoscópica (estadio pT3a). En tomografía computarizada (TC) control a los 5 años se evidencia lesión focal en la periferia del segmento IVa, ante la sospecha de malignidad, se realiza laparotomía exploradora revisando toda la cavidad abdominal sin evidenciar otros implantes peritoneales. Se halla un nódulo de 1 cm en el ligamento redondo y se realiza su exéresis completa, con diagnóstico anatomopatológico de metástasis de células claras. El LR generalmente está afectado en casos de carcinomatosis peritoneal y solo existen dos casos publicados de metástasis únicas.
The falciform ligament is a peritoneal reflection that attaches the liver to the anterior abdominal wall; its lower edge contains the round ligament (RL). Single lesions in the RL are rare and usually correspond to perivascular epithelioid cell tumors. We present a case report of a single metastasis in the RL in a patient with clear cell renal cell carcinoma who underwent surgery five years ago. We conducted a literature review to identify similar cases and we found two case reports of single metastasis in the RL. Our patient was a 71-year-old man with a history of renal cell carcinoma who underwent left laparoscopic radical nephrectomy (stage pT3a), laparoscopic right adrenalectomy and total thyroidectomy due to multinodular goiter. The pathological examination revealed metastases of renal cell carcinoma. A computed tomography (CT) scan performed at 5-year follow-up showed a focal lesion in segment IVa with no FDG uptake in the PET scan, but as malignancy was suspected, the patient underwent exploratory laparatomy with no evidence of peritoneal implants. A 1-cm node was found in the round ligament that was completely resected. The pathological examination revealed metastatic clear cell renal cell carcinoma. The RL is involved in cases of peritoneal carcinomatosis and only two cases of single metastasis have been reported: in one patient with papillary renal cell carcinoma pT1aN0 and another one with left breast adenocarcinoma.

OBJECTIVE@#To investigate the safety and feasibility of laparoscopic treatment for renal carcinoma with Mayo 0-2 level venous thrombosis.@*METHODS@#From January 2015 to February 2018, 58 renal carcinoma cases with venous thrombus underwent laparoscopic radical nephrectomy with inferior vena cava thrombectomy in Department of Urology, Peking University Third Hospital, of which, 51 cases were male, and 7 female, aged 29-82 years. According to the Mayo grade classification, 20 cases were level 0, 20 cases were level 1, and 18 cases were level 2, with left side being 22 cases, and right side 36 cases. The patients except for those complicated with hemorrhagic diseases, cardiac and pulmonary insufficiency, or those who could not tolerate anesthesia and surgical contraindications, underwent the operation after comprehensive examinations.@*RESULTS@#The 58 cases of renal tumor with venous tumor emboli were successfully completed with the surgeries, including 50 cases of totally laparoscopic surgery, 8 cases of laparoscopy surgery from convert to open (among the patients who were converted to open surgery, 7 were complicated with grade 2 tumor thrombus and 1 with grade 1 tumor thrombus). The main reasons for converting to open surgery were huge tumors (the largest of which was about 16 cm in diameter), severe adhesion and difficulty of separation. For different patients, different surgical methods and procedures were adopted according to the tumor direction and the different grade of tumor thrombus. Radical nephrectomy combined with vena cava tumor thrombus removal was performed in 55 cases and segmental resection of vena cava in 3 cases. The operation time was 132-557 min, and blood loss was 20-3 000 mL. Post-operative pathological types: 51 cases were clear cell carcinoma, 5 cases were type 2 of papillary carcinoma, 1 case was squamous cell carcinoma, and 1 case was chromophobe cell tumor. In the study, 47 cases were followed up for 1-36 months, and 4 cases died (the survival time was 5-15 months, with an average of 10.2 months).@*CONCLUSION@#Laparoscopic radical nephrectomy with inferior vena cava thrombectomy is a reasonable choice for renal tumor with Mayo 0-2 level venous thrombosis. For different tumor directions and different grades of tumor thrombus, an appropriate operation plan can give the maxim benefit to the patients with skillful surgeons.

SUMMARY Ectopic adrenocorticotropic hormone (ACTH) syndrome is characterized by hypercortisolism due to the hypersecretion of a non-pituitary ACTH-secreting tumor leading to Cushing's syndrome. Only a few cases have been reported previously as causing ectopic ACTH related to paraganglioma. Herein, we present a case of Cushing's syndrome, in who was proved to be attributable to an ACTH-secreting renal malignant paraganglioma. A 40-year-old woman presented with a five-month history of newly diagnosed hypertension and diabetes, weakness, hyperpigmentation, oligomenorrhea, hirsutism, and acneiform lesions. She showed cushingoid features, including moon face, facial hirsutism, facial and truncal acne, hyperpigmentation, and severe muscle weakness of the limbs. She did not have other findings such as striae, supraclavicular fat accumulation, and buffalo hump. Laboratory examination showed the presence of hypopotasemia, hyperglycemia, hyperthyroidism, and leukocytosis. The serum levels of ACTH, cortisol, and urine-free cortisol were markedly elevated. Results of an overnight 2-mg dexamethasone suppression test included a basal serum cortisol of 61.1 mcg/dL (normal range: 4.6-22.8 mcg/dL) and a cortisol value of 46.1 mcg/dL after dexamethasone administration. There was no suppression found after 2-day 8-mg dexamethasone administration. Magnetic resonance imaging (MRI) of the pituitary gland indicated two microadenomas. An abdominal MRI scan revealed horseshoe kidney, bilateral adrenal hyperplasia, and masses with dimensions of 35 x 31 mm in the left kidney. Inferior petrosal sinus sampling showed no evidence of a central-to-peripheral gradient of ACTH. A positron emission tomography/computed tomography scan showed intense increased activity in the lower pole of the left kidney. Left adrenalectomy and left partial nephrectomy were performed. The resected tumor was diagnosed as the ACTH-secreting paraganglioma in the pathological examination, which was confirmed by immunohistochemical studies with chromogranin A, synaptophysin, and ACTH. Only a few cases of paragangliomas as a cause of ectopic ACTH syndrome have been reported. To our knowledge, this is the first case of renal paraganglioma resulting in Cushing's syndrome due to ectopic ACTH hypersecretion.

SUMMARY Paraneoplastic syndromes are a heterogeneous group of malignant diseases caused by events which involve endocrine, immune and metabolic aspects and whose symptoms vary according to the substance produced and the primary tumor. Hypercalcemia is a frequent complication in cancer patients. Prognosis of cancer patients with hypercalcemia is usually poor. A factor called parathyroid hormone related peptide, whose actions are similar to those of the parathyroid hormone, is thought to be the most common cause of malignancy associated hypercalcemia. Non-islet hypoglycemic cell tumor consists of a rare syndrome characterized by the presence of a solid tumor and severe fasting hypoglycemia determined by an insulin-independent pathway. We report a case of a 59-year-old-man with a renal tumor and a T-cell rich large B cell lymphoma who was hospitalized due to severe hypercalcemia and hypoglycemia. The laboratory examination reported hypercalcemia with inhibited PTH and hypoglycemia with inhibited insulin secretion, arriving to the conclusion of tumoral peptide production. He received denosumab and corticoid therapy. The patient died one month later despite initial improvement after medical treatment. While a single paraneoplastic manifestation may be expected in most tumors, the coexistence of two or more of them is rare, except in hepatocellular carcinomas, and it has not yet been described in renal tumors.

Main findings A 25-year-old hypertensive female patient was referred to our institution. Initial workup exams demonstrated a 2.8 cm cortical lower pole tumor in the right kidney. She underwent laparoscopic partial nephrectomy without complications. Histopathologic examination revealed a rare juxtaglomerular cell tumor known as reninoma. After surgery, she recovered uneventfully and all medications were withdrawn. Case hypothesis Secondary arterial hypertension is a matter of great interest to urologists and nephrologists. Renovascular hypertension, primary hyperadosteronism and pheocromocytoma are potential diagnosis that must not be forgotten and should be excluded. Although rare, chronic pyelonephritis and renal tumors as rennin-producing tumors, nephroblastoma, hypernephroma, and renal cell carcinoma might also induce hypertension and should be in the diagnostic list of clinicians. Promising future implications Approximately 5% of patients with high blood pressure have specific causes and medical investigation may usually identify such patients. Furthermore, these patients can be successfully treated and cured, most times by minimally invasive techniques. This interesting case might expand knowledge of physicians and aid better diagnostic care in future medical practice. .

Renal angiomyolipoma is a benign tumor, composed of adipocytes, smooth muscle cells and blood vessels. The association with pregnancy is rare and related with an increased risk of complications, including rupture with massive retroperitoneal hemorrhage. The follow-up is controversial because of the lack of known cases, but the priorities are: timely diagnosis in urgent cases and a conservative treatment when possible. The mode of delivery is not consensual and should be individualized to each case. We report a case of a pregnant woman with 18 weeks of gestation admitted in the emergency room with an acute right low back pain with no other symptoms. The diagnosis of rupture of renal angiomyolipoma was established by ultrasound and, due to hemodinamically stability, conservative treatment with imaging and clinical monitoring was chosen. At 35 weeks of gestation, it was performed elective cesarean section without complications for both mother and fetus.
O angiomiolipoma é um tumor benigno, constituído por adipócitos, células de músculo liso e vasos sanguíneos. Sua associação com a gravidez é rara e está relacionada com um aumento de complicações, nomeadamente rotura com hemorragia retroperitoneal maciça. O follow-up é controverso em razão do escasso número de casos descritos, no entanto as prioridades são: diagnóstico atempado nas situações urgentes e, sempre que possível, tratamento conservador. O tipo de parto não é consensual e deve ser individualizado caso a caso. Relatamos um caso de uma grávida com 18 semanas de gestação que recorreu ao serviço de urgência por lombalgia direita aguda, sem outros sintomas relevantes. Diagnosticou-se ecograficamente rotura de angiomiolipoma renal e, em decorrência da estabilidade hemodinâmica do quadro, procedeu-se ao tratamento conservador com monitorização imagiológica e clínica. Às 35 semanas de gestação, realizou-se uma cesariana eletiva que decorreu sem complicações maternas ou fetais.

BACKGROUND/AIMS: Sunitinib is an oral multitargeted tyrosine kinase inhibitor used mainly for the treatment of metastatic renal cell carcinoma. The renal adverse effects (RAEs) of sunitinib have not been investigated. The aim of this study was to determine the incidence and risk factors of RAEs (proteinuria [PU] and renal insufficiency [RI]) and to investigate the relationship between PU and antitumor efficacy. METHODS: We performed a retrospective review of medical records of patients who had received sunitinib for more than 3 months. RESULTS: One hundred and fifty-five patients (mean age, 58.7 +/- 12.6 years) were enrolled, and the mean baseline creatinine level was 1.24 mg/dL. PU developed in 15 of 111 patients, and preexisting PU was aggravated in six of 111 patients. Only one patient developed typical nephrotic syndrome. Following discontinuation of sunitinib, PU was improved in 12 of 17 patients but persisted in five of 17 patients. RI occurred in 12 of 155 patients, and the maximum creatinine level was 3.31 mg/dL. RI improved in two of 12 patients but persisted in 10 of 12 patients. Risk factors for PU were hypertension, dyslipidemia, and chronic kidney disease. Older age was a risk factor for RI. The median progression-free survival was significantly better for patients who showed PU. CONCLUSIONS: The incidence of RAEs associated with sunitinib was lower than those of previous reports. The severity of RAEs was mild to moderate, and partially reversible after cessation of sunitinib. We suggest that blood pressure, urinalysis, and renal function in patients receiving sunitinib should be monitored closely.

Radio-frequency ablation (RFA) is a curative treatment for hepatocellular carcinoma (HCC). Percutaneous RFA has been shown to be beneficial for patients with small renal cell carcinoma (RCC) lacking indications for resection. We experienced the case of a 53-year-old male who had conditions that suggested HCC, RCC, and alcoholic liver cirrhosis. Abdominal contrast-enhanced computed tomography (CT) and magnetic resonance image showed liver cirrhosis with 2.8 cm ill-defined mass in segment 2 of the liver and 1.9 cm hypervascular mass in the left kidney. These findings were compatible with the double primary cancers of HCC and RCC. Transarterial chemoembolization (TACE) was performed to treat the HCC. After the TACE, a focal lipiodol uptake defect was noticed on a follow up CT images and loco-regional treatment was recommended. Therefore, we performed RFAs to treat HCC and RCC. There was no evidence of recurrence in the follow up image after 1 month.

El Cáncer Renal se presenta habitualmente como un hallazgo de las imágenes abdominales y cuando se manifiesta clínicamente lo hace a través de los efectos que produce una gran masa abdominal o las metástasis a distancia. En este trabajo se presenta un caso de cáncer renal cuyas manifestaciones clínicas fueron secundarias a la obstrucción de las venas supra hepáticas, es decir un síndrome de Budd-Chiari florido por la presencia de un trombo tumoral en la cava retro hepática. El diagnóstico oportuno y una evaluación adecuada con imágenes permitieron la ejecución de un plan de tratamiento que incluyó un abordaje combinado abdominal y torácico que permitió un tratamiento no solo sintomático sino que potencialmente curativo de un cáncer renal con esta rara presentación.
Renal Cancer usually occurs as a finding of abdominal imaging and when it clinically manifests itself it does so through a large abdominal mass or distant metastases. In this paper we present a case of renal cancer whose clinical manifestations were secondary to obstruction of hepatic veins, a Budd-Chiari syndrome because of the presence of a tumor thrombus in the retro hepatic vena cava. Early diagnosis and appropriate imaging evaluation allowed the implementation of a treatment plan that included a combined abdominal and thoracic approach allowing not only a symptomatic treatment but potentially curative treatment of renal cancer with this rare presentation.

La endoftalmitis endógena puede ocurrir en aquellos casos de inflamación de los tejidos oculares internos secundaria a infección intraocular, resultado de la diseminación hematógena de los microorganismos desde un foco distal al ojo. Es el grupo menos frecuente de todas las endoftalmitis (5 por ciento), es preferentemente unilateral, y en la mayoría de los pacientes se aprecia al menos un foco extraocular infeccioso. Aunque puede darse en pacientes sanos inmunocompetentes, esta enfoftalmitis afecta fundamentalmente a pacientes con uno o más factores de riesgo, entre ellos, enfermedades crónicas, procedimientos quirúrgicos, neoplasias, usuarios de drogas administradas por vía parenteral, inmunodeficiencias, catéteres intravenosos. Se presenta un caso de una paciente diabética con una endoftalmitis endógena secundaria a un tumor renal, cuyo cuadro inicial apuntaba hacia un coma diabético y en la medida que evolucionó y a través del estudio oftalmológico se logró un completo diagnóstico y tratamiento de su problema de salud
The endogenous endophthalmitis may occur in cases of internal tissue inflammation secondary to intraocular infection, as a result of the hematogenous dissemination of microorganisms from a distal focus to the eye.
