  • Multilocular cystic nephroma is a rare disease, noninherited benign renal neoplasm occurring in both children and adults. It is necessary to make a differential diagnosis from all renal diseases with a cystic component, such as Wilms tumor, harmatoma or polycystic dysplastic kidney in childhood. There are about only 200 case reports in the world since Walter Edmunds had described it first. We report a case of multilocular cystic nephroma presented with painless abdominal mass, treated with nephrectomy and confirmed with pathology. (J. Korean Soc Pediatr Nephrol 2001 ;5 : 219-24)

  • Neuroblastoma arises from the embryonic tissue of the adrenergic rest. It is commonly found in children and mostly in nonrenal tissue. We present a case of intrarenal neuroblastoma which was initially thought to be a Wilms' tumor. The patient was a 18 months-old girl treated with radical nephrectomy and adjuvant chemotherapy after operation. The neoplasm within the kidney in children cannot always indicate Wilms' tumor. Neuroblastoma of the adrenal gland or retroperitoneal tissue may often compress or invade the kidney directly or arise from the kidney. Clinical aspects that differentiate between neuroblastoma and Wilms' tumor are discussed with a review of the literatures.

  • A 12-year-old dog was evaluated for depression and anorexia. The results of complete blood count and serum biochemistry were normal. Survey radiographs revealed markedly enlarged right kidney and abdominal ultrasound showed a renomegaly and hydronephrosis filled with mixed echogenic fluid. Primary renal tumor was suspected in this dog. Nephroureterectomy of the right kidney was performed, and no regional metastases have been identified. Transitional cell carcinoma (TCC) arising from renal pelvis accompanied hydronephrosis of the right kidney was diagnosed on histology. TCC usually affects trigone of the bladder, and renal origin of TCC is a very rare finding in dogs. This is the first case report to present the clinical features, diagnostic imaging findings and histopathological characteristics of a dog with TCC originating from the renal pelvis in Korea.

  • A seven-year-old female Jindo-dog was presented with a history of progressive abdominal distension. Except for severe bilateral abdominal swelling, other abnormal signs were not detected. The patient showed normal appetite and defecation. In the radiographic examination, the abdomen was filled with large masses. Suspected a certain neoplastic disease, laparotomy was taken through the cranial abdominal midline. Large pale-yellow masses were proliferated to fill the abdomen. In the masses, grey-brown or black portion presumed hemorrhagic or necrotic spots were found. Even though neoplastic tissues were not detected in the right kidney, they were infiltrated in the left kidney except for a part of the cortex. Obtaining the owner's consent, the patient was euthanized and samples were collecte for further study. In microscopic examination, the parenchyma of the medulla was substituted with tumor cells and the cortex was impressed by the expansive proliferation of the neoplastic tissues. This neoplasm was estimated as renal carcinoma originated from tubular epithelium, being based upon that tumor cells were largely cuboidal cells and they had obscure tubular forms.

  • Multilocular cystic renal neoplasm of low malignant potential (MCRNLMP) is a rare subtype of renal cell carcinoma that has a favorable outcome. Most cases of MCRNLMP usually present as distinct multilocular cystic lesions; however, they may appear as small complicated cysts with hemorrhagic components. Herein, we present a case of MCRNLMP and provide a review of the literature.

  • Plasma cell myeloma is malignant disease of plasma cell in the bone marrow. Myeloma accounts for about 1% of all cancers. The solitary plasma cellmyeloma is rare tumors and account for less than 10% of plasma cell neoplasm. It is often progress to multiple myeloma at 30-40% despite successful local treatment with surgery and radiation therapy. We are reporting a case of solitary plasma cell myeloma on anterior maxillary region that developed after kidney transplantation and immunosuppressive therapy.

  • Non small cell lung cancer (NSCLC) frequently metastasizes to brain, bone, liver, and adrenal glands. While an autopsy of NSCLC reveals some cases of metastasis to the kidney, clinical detection of renal metastases is extremely rare. Furthermore, metastases to the kidney usually present as multifocal or bilateral lesions and solitary renal metastases are usually suspected to be renal cell carcinoma. We now report a case of asymptomatic solitary renal metastasis from a primary squamous cell carcinoma, which was detected by routine surveillance with abdominal CT after curative surgery.

  • Malignant schwannoma is rare tumor which is derived from schwas cells or nerve sheath cells, and it is frequently associated with Von Rechlinghausen's disease. We experienced one case of malignant schwannoma on the right chest wall without Von Rechlinghausen's disease. Patient was 64-year-old man who presented painless palpable mass on the right lower -chest wall for about 2 months. On chest computed tomography, the mass which was 6$\times$6 cm in size and had central necrosis, involved 11th rib with destruction, invaded the diaphragm and displaced the kidney anteriorlly. He underwent on-bloc resection of the tumor and discharged without any problem after 20 days.

  • Concomitant renal cell carcinomas (RCC) of both native and allograft kidneys are extremely rare, and only a few cases have been reported in the available English literature. A particularly rare variant within the adult population is the Xp11.2 translocation/transcription factor E3 (TFE3)-rearranged RCC. Although few case reports of TFE3-rearranged RCC have been reported in children who underwent kidney transplantation (KT), no case of adults with TFE3-rearranged RCC following KT has been reported. Herein, we presented the radiological and pathological findings of a rare metachronous papillary RCC in the allograft kidney and TFE3-rearranged RCC in the native kidney. The TFE3-rearranged RCC in the native kidney exhibited slow expansion in size over five years. Radiologically, it appeared as a slightly enhanced, lobulated mass on contrast-enhanced CT. MRI revealed high signal intensity on T1-weighted images and low signal intensity on T2-weighted images.

  • Urinothorax occurs when urine leakes into thoracic cavity and it was first reported by Correie in 1968. The mechanism of its occurrence is an accumulation of urine in thoracic cavity by retroperitoneal urinoma formed by urinary tract obstruction or trauma. Retroperitoneal inflammation, malignant neoplasm, kidney transplantation, and kidney biopsy can also induce urinothorax. The diagnosis of urinothorax may be delayed due to its rare incidence rate, but if diagnosis is confirmed the treatment is possible by urinary diversion. We report our experience of a case of urinothorax associated with retroperitoneal urinoma followed by blunt renal trauma with review of literatures.
