The MN/CA9 protein is a tumor-associated antigen that has been shown to have diagnostic utility in identifying cervical dysplasia and carcinoma. MN/CA9 expression is limited to very few normal tissues. We have now extended those observations to further investigate expression of the MN/CA9 protein in histological sections and fine-needle aspiration biopsy smears of normal kidney, benign renal ce...

Cystic and bile duct dysplasia is a rare histological finding, especially when found in the absence of an underlying malignancy. We report a patient who presented with jaundice and weight loss. Clinical and cytological evidence suggested a diagnosis of cholangiocarcinoma and the patient underwent a pancreatico-duodenectomy. Histopathological examination suggested a diagnosis of two foci of bili...

Introduction: Neonatal hypertension (HT) is an emerging challenge for neonatologists and pediatricians around the world. The prevalence of renal causes neonatal due to congenital anomalies malformations including obstructive uropathy cystic kidney disease not well estimated up till now. Early diagnosis corner stone good prognosis better outcome. Aim study: To determine in apparently healthy ter...

717 ibrous dysplasia is a developmental anomaly that can affect any bone in the body. The skull and facial bones are the affected sites in 10–25% of patients with monostotic fibrous dysplasia and in 50% of patients with polyostotic fibrous dysplasia. Conventional radiographic findings reveal characteristics of fibrous dysplasia. CT findings also show characteristics of fibrous dysplasia and con...

Background : Cystic renal cell carcinoma has been reported to have a good prognosis. However, previous studies included cases of multilocular cystic renal cell carcinoma, which has an excellent prognosis, and renal cell carcinoma with cystic necrosis, which has an adverse prognosis. Therefore, we analyzed the prognostic influence of cystic change in clear cell renal cell carcinoma after excludi...

We present an unusual case of concurrent occurrence of a multilocular cystic renal cell carcinoma and a leiomyoma in the same kidney of a patient with no evident clinical symptoms. A 38-year-old man was found incidentally to have a cystic right renal mass on computed tomography. Laparoscopic radical nephrectomy was performed under a preoperative diagnosis of cystic renal cell carcinoma. Histolo...

Multicystic dysplastic kidney is the most common type of renal cystic disease, one of the most common cause of an abdominal mass in infants. A multicystic dysplastic kidney contains non-communicating multiple cystic spaces varying in size and has no functioning renal tissue. there is a possibly results that it from abnormal metanephros differentiation, probably due to disturbed connection of ur...

Cystic renal neoplasms and renal epithelial stromal tumors are diagnostically challenging and represent some novel tumor entities. In this article, clinical and pathologic features of established and novel entities are discussed. Predominantly cystic renal tumors include cystic nephroma/mixed epithelial and stromal tumor, synovial sarcoma, and multilocular cystic renal cell carcinoma. These ent...

Pediatric respiratory disease related to congenital and genetic etiologies are important topics found on the USMLE. Congenital disease to be aware of include Diaphragmatic hernias, congenital cystic adenomatoid malformation, surfactant deficiency, pediatric pulmonary hypoplasia, and bronchopulmonary dysplasia. Genetic disease to be aware of include cystic fibrosis, alpha 1 antitrypsin, and prim...
