Renal inflammatory pseudotumor is a very rare benign condition of unknown etiology characterized by proliferative myofibroblasts, fibroblasts, histiocytes, and plasma cells. We report a case of inflammatory pseudotumor of the kidney. A 42-year-old female was admitted with the complaint of right flank pain. Computerized tomography revealed a tumor, 7 cm in diameter, in the upper pole of the right kidney. Right radical nephrectomy was performed under the diagnosis of renal cell carcinoma. Histological examination demonstrated a tumor composed of spindle-shaped fibroblastic cells infiltrated by variable numbers of plasma cells, small lymphocytes and histiocytes. The pathologic diagnosis was renal inflammotory pseudotumor.

Simultaneous occurrence of renal cell carcinoma (RCC) and transitional cell carcinoma (TCC) in the same kidney is unusual. We report a 61-year-old man with ipsilateral synchronous renal adenocarcinoma and renal pelvic TCC. He was referred to our department for gross hematuria and right flank pain. CT and MRI studies revealed a 57 x 50 mm irregular and infiltrative upper right kidney mass with necrotic components. A right radical nephrectomy was done. Pathological diagnosis was a high grade tumor originating from just beneath the intact urothelium of renal pelvis and infiltrating through the parenchyma showing solid and occasional tubular growth patterns. A second tumor in close proximity to the first was reported as well differentiated RCC. This is a rare case of combined renal malignancies.

Renal cell carcinoma arising from epithelial cells of the renal tubule is a highly aggressive and malignant tumor in all ages. Less than 2% of cases occur in childhood, relatively in older age group. Only a few pediatric series have been presented in the English literature. Tumor is presented with characteristic findings of flank pain, gross hematuria, and palpable mass. Although one half of the patients have metastasis at the time of diagnosis, most cases are currently being incidentally detected using improved imaging techniques. The overall prognosis in children appears to be similar to that in adults. Tumor stage and complete surgical resection have been reported as the most meaningful prognostic factors for the outcome. The incidence of metastatic disease is same as in adults. The effect of chemotherapy and immunotherapy, either preoperatively or postoperatively, is unclear. Cure is the most likely consequence in localized and completely resected tumors. Here, we present an 8-year-old boy with renal cell carcinoma demonstrating only hematuria without any pathological physical examination findings. The mass was described by abdominal ultrasonography and computed tomography in the left kidney. After the left nephroureterectomy, the patient was given no therapy.

We report a rare case of asymptomatic adrenal medullary hyperplasia detected by chance with intraoperative hypertension during surgery for ipsilateral renal cell carcinoma. A 41-year-old male visited our hospital with a complaint of left flank pain. He had normal blood pressure and plasma catecholamine level was within normal limits. Ultrasonogram and CT scan revealed a left renal tumor but did not showed any abnormal masses in the left adrenal gland. The clinical diagnosis was renal cell carcinoma and we performed left total nephrectomy. In the process of operative manipulation, however, the blood pressure and pulse rate of this patient showed a marked increase. Pathological examination of the extirpated kidney revealed renalcell carcinoma, while the resected adrenal gland was diagnosed as adrenal medullary hyperplasia.

We report a case of renal cell carcinoma who presented with the classic triad of flank pain, hematuria and fever as well as progressively developed multisystem disease, including a massive anteroseptal myocardial infarction. This was diagnosed as paraneoplastic syndrome of renal cell carcinoma and the decision to proceed with nephrectomy was taken after 3 weeks of acute myocardial infarction, despite predicted high cardiac risk under general anaesthesia; following removal of tumour, all symptoms and signs regressed. He has remained well till the time of last follow-up 4 months later.

Focal Xanthogranulomatous Pyelonephritis (XGPN) may be erroneously interpreted as renal cell carcinoma. We report a case of a young Philippino who presented with persisting right flank pain for 2 years. Imaging showed a well-delineated lesion in the lower pole of the right kidney extending to the hilum. Nephrectomy was performed under a tentative diagnosis of renal cell carcinoma, whereas histology revealed focal XGPN. Pre-operative diagnosis of focal XGPN was difficult because of radiological similarities to renal cell carcinoma and lack of the usual clinical presentation.

Renal cell carcinoma (RCC) is a relatively uncommon tumor in childhood. Its biologic behavior and prognostic factors have rarely been documented. We report treatment and survival of 4 children (aged 8, 9, 11, and 14 years) who had RCC, along with a review of the literature to analyze the frequency of major symptoms, clinical stage, and prognostic factors based on 130 published cases of RCC in individuals younger than 20 years of age. Two of our cases had renal tumors detected by ultrasound screening, and all 4 cases were followed for a considerable length of time and were alive and free of disease after treatment. An analysis of these 130 published cases of pediatric RCC showed tumor staging and cell type to be the factors that affected patient survival. Tumors composed of granular cells or mixed cells, or at advanced stages, had a poor prognosis. Age, sex, tumor size, symptom duration, and cellular pattern were not related to patient prognosis. Children older than 10 years of age, who have an abdominal mass, flank pain, and/or hematuria should alert clinicians to consider the possibility of RCC. The importance of early diagnosis of renal tumors, using ultrasound as a tool of screening, is emphasized, since surgical treatment leads to a favorable prognosis only in the early stage of RCC.

Arteriovenous malformations are important but uncommon differential diagnoses for space occupying renal lesions with unknown genesis. In the following case report, a 41-year-old patient complained about continuing right flank pain. Computer tomography indicated a possible renal cell carcinoma and the patient was admitted to our clinic. Further diagnostics, including contrast medium-enhanced bolus CT, colour coded duplex sonography, renovasography and MR-angiography, revealed a large arteriovenous fistula of the entire right kidney. Because of the size and aneurysmatic appearance of this fistula, we performed a nephrectomy. Since this operation the patient has been free of complaints.

Renal cell carcinoma (RCC) in childhood is a unique disease entity, representing only 2.3-6.6% of all renal tumors in children. Most experience with pediatric RCC is limited to case reports or case series consisting of relatively small numbers of cases. The aim of this study is to present four additional cases of this unique disease entity. The records of four patients presenting to our institution with renal cell carcinoma between 1986 and 2006 were examined. Only patients younger than 10 years were included. The clinical data included age, sex, signs and symptoms, surgery performed and clinical outcome. Data recorded from the pathology reports included tumor size, histologic subtype, grade (WHO), and stage (TNM). There were three boys and one girl aged between 11 months and 10 years at presentation. The classic triad of flank pain, gross hematuria and palpable abdominal mass were not encountered. A histopathological diagnosis of RCC was confirmed in all four cases without any positive lymph node involvement. Due to the increased detection of tumors with the use of imaging techniques such as ultrasound and computerized tomography, an increased number of incidentally diagnosed RCCs are found. The primary choice of the treatment of any stage of RCC is surgical excision. However, the preoperative diagnosis of tumor in children is difficult and the effects of chemotherapy, including immunotherapy, are unclear.

Renal cell carcinoma (RCC) usually remains clinically silent posing a great challenge to early diagnosis. The classic triad of flank pain, hematuria, and flank mass is uncommon and presents in only 10% of cases. RCC is frequently associated with various paraneoplastic syndromes. We report a case of an elderly female with sarcomatoid renal cell carcinoma presenting with acute pancreatitis (paraneoplastic phenomenon), and provide a brief review of the literature. The diagnosis is established on the basis of radiological findings and histopathology.
