A 50-year-old man, who had undergone operation of esophageal carcinoma 2 years earlier, was admitted with the complaints of right flank pain and macroscopic hematuria. Intravenous urogram showed right unvisualized kidney. Right retrograde pyelography showed the dilatation of calices and irregularity of middle and lower calices. Computed tomography revealed severe hydronephrosis of the right kidney. Right nephrectomy was performed under the diagnosis of either renal pelvic cancer or esophageal cancer metastatic to the kidney. Pathological examination revealed metastatic squamous cell carcinoma from esophagus. The patient was treated by radiotherapy but died 4 months after the surgical treatment. Literature on eight case of metastatic renal cancer from esophagus is reviewed.

The patient was a 74-year-old man who was referred to our hospital with a complaint of left flank pain. Laboratory data were almost within normal limits and urine cytology was positive. X-ray examination revealed a calcification in the left kidney and abdominal CT scan confirmed the presence of a heterogenous renal pelvic mass which contained a calcification. Based on these examinations, a diagnosis of a renal pelvic cancer with heterotopic bone formation was made. Subsequently, left nephroureterectomy was performed. Grossly, the renal pelvis of the resected kidney was filled with a mass which had a white cut surface and bone-like tendency. Histopathologically, a poorly differentiated transitional cell carcinoma with massive bone formation was found. Fifty five cases of heterotopic bone formation in the kidney have been reported in Japan. Among the cases, 4 cases were complicated with renal pelvic tumor and our case was the second case of heterotopic bone formation complicated with a transitional cell carcinoma of the renal pelvis in Japan.

A 73-year-old man was admitted to the hospital complaining of gross hematuria and left flank pain. Abdominal ultrasonography and computed tomography revealed a left renal tumor with extracapsular extension. Laboratory data showed marked leukocytosis of 121,000/mm3 and hypercalcemia of 12.3 mg/dl without any findings of inflammatory disease or bone metastasis. Enzyme immunoassay of the serum demonstrated a high level of granulocyte colony-stimulating factor (250 pg/ml) and parathyroid hormone-related protein (1,069 pmol/l). Pathological diagnosis of needle biopsy specimen of the primary tumor was transitional cell carcinoma which was suspected to have originated from renal pelvis. Immunohistochemical examination with anti-granulocyte colony-stimulating factor monoclonal antibody demonstrated granulocyte colony-stimulating factor production in cancer cells. The patient underwent a course of systemic chemotherapy, but died two months after diagnosis. To our knowledge, this is the first report of renal pelvic cancer representing granulocyte colony-stimulating factor production and hypercalcemia simultaneously.

IgG4-related sclerosing disease is a novel clinicopathological entity characterized by fibrosis, extensive infiltration of IgG4-positive plasma cells, and serum IgG4 elevation. This disorder includes a variety of diseases, such as autoimmune pancreatitis, retroperitoneal fibrosis, sialadenitis, thyroiditis, inflammatory abdominal aneurysm, tubulointerstitial nephritis, and inflammatory pseudotumor [World J Gastroenterol 2008;14:3948-3955]. A 71-year-old man visited our hospital with the complaint of left flank pain and gross hematuria. Computed tomography (CT) revealed left hydronephrosis and a thick retroperitoneal soft tissue mass around the ureteropelvic junction, suspicious of renal pelvic cancer. Urine cytology using a urine sample from the left renal pelvis was negative. On laboratory examination, serum levels of IgG and IgG4 were found to be elevated. The patient refused tumor biopsy. Therefore, he was treated with corticosteroid therapy on the basis of a clinical diagnosis with IgG4-related retroperitoneal fibrosis. Regression of the retroperitoneal mass as well as improvement of left hydronephrosis and decrease in serum IgG4 levels were accomplished. These effects strongly suggested that the present case was an IgG4-related retroperitoneal fibrosis. However, in this instance, since we could not completely rule out malignancies by biopsy, careful follow-up was necessary with these points in mind.

Background: Kidney and renal pelvic cancer was the sixth most common cancer in men and 10th most common in women in the United States in 2018. Renal cell carcinoma (RCC), accounts for 86% of malignancies of the kidney. RCC patients are often asymptomatic; up to 25-30% have metastases at diagnosis. Few present with the triad of gross hematuria, flank pain, and abdominal mass. In RCC patients, 36% had 2 symptoms of the triad, and 60% had gross hematuria as 1 symptom. Point-of-care ultrasound (POCUS) offers a way to identify clinically meaningful anatomic abnormalities. This case series presents 3 patients in whom routine POCUS examination performed in an outpatient cardiology clinic found asymptomatic renal masses, resulting in surgical resection and cure of early-stage RCCs. Case Presentation: Patient 1: 54-year-old female with hypertension (HTN). Two solid masses were identified with POCUS in the right kidney. Patient 2: 63-year-old male with coronary artery disease (CAD) and HTN was seen at an 8-month follow-up visit. A 6-cm mass was identified in the left kidney. Patient 3: 69-year-old male with CAD, HTN, and smoking history seen at 5-month follow-up visit. A 3-cm mass in the right kidney was identified. Conclusions: Incorporating POCUS into the routine physical examination in the ambulatory care setting may improve rates of detection and increase the pretest probability of identifying renal pathology with formal imaging studies. With minimal clinician training, earlier and increased detection of asymptomatic RCC may result in improved patient survival.
