We report our experience of a concurrent robot assisted distal gastrectomy and partial nephrectomy for synchronous early gastric cancer and renal cell carcinoma. A 55-year-old female patient was diagnosed with early gastric cancer on screening endoscopy. Abdominal computed tomography showed an incidental right renal cell carcinoma. Robot assisted distal gastrectomy was performed, followed by partial nephrectomy. The final pathological examination showed signet ring cell carcinoma within the lamina propria and renal cell carcinoma with negative resection margins. The patient showed no evidence of recurrence at 6-months. A robot-assisted combined operation could be a treatment option for early stages of synchronous malignancies.

Page kidney refers to the phenomenon of hypertension secondary to long-standing compression of renal parenchyma caused by renal subcapsular collection. The most common cause of renal subcapsular collection is a hematoma which usually occurs after a history of blunt trauma. A 42-year-old female patient who received botulinum toxin injection in her back during chiropractic care was admitted to the emergency room with sudden bilateral flank pain and hypertension. The computed tomography (CT) images demonstrated the presence of bilateral subcapsular renal hematoma. The patient was treated conservatively and recovered well. The follow up CT images showed markedly resolved bilateral hematoma.

Brown tumor is a histologically benign lesion that is a serious complication of renal osteodystrophy because it may result in severe deformity and discomfort. We report a case of brown tumor, which occurred in a 35-year-old woman with chronic renal failure, who had been treated with hemodialysis for 14 years. The lesion was found on the lingual side of the mandible. Standard panoramic radiograph showed generally decreased bone mineral density, loss of lamina dura, and thin cortical plates. Computed tomography (CT) revealed multilocular expansile lesions with heterogeneous attenuation in the anterior mandible, as well as generalized trabecular alteration with homogeneous sclerosis, and thinning or obliteration of cortical plates. Excision of the mandibular lesion and curettage of the affected bone were performed. (Korean J Oral Maxillofac Radiol 2008; 38: 229-31)

심근 석회화는 다양한 원인으로 인해서 발생할 수 있다. 하지만 패혈증과 신부전으로 인해서 발생하는 경우는 흔하지 않다. 저자들은 컴퓨터단층촬영과 자기공명영상에서 패혈증과 신부전을 회복한 환자에서 급속하게 좌심실벽에 미만성 석회화를 보이는 증례를 보고하고자 한다.

A 10-year-old female Pomeranian weighing 2.25 kg with a history of gradual weight loss and an intraabdominal mass confirmed with ultrasonography at a local hospital was referred to the Veterinary Medical Teaching Hospital, Jeju National University. Physical examination revealed abdominal distention. Blood analysis revealed hypoglycemia (57 mg/dL; reference range, 60-110 mg/dL). On abdominal ultrasonography, a heterogeneously hyperechoic mass measuring 7.51 × 10.6 cm was found at the level of the left kidney. Computed tomographic findings showed a unilateral left kidney mass with a 10-cm diameter and vessel contrast enhancement in the corticomedullary phase. Unilateral nephrectomy and ovariohysterectomy were performed because left ovary enlargement was observed during surgery. The renal mass was adjacent to the aorta and vena cava and attached to a portion of the small intestine, greater omentum, and left ovary. The mass was huge (12.5 × 10 × 7 cm) and was 16.5% of the body weight. Histopathological examination revealed renal cell carcinoma (RCC) and ovarian metastasis. After surgery, clinical signs improved remarkably, and serum glucose level returned to normal. As RCC is resistant to radiation and chemotherapy, the owner decided not to proceed with postoperative adjunctive therapies. To the best of our knowledge, this is the first case report of ovarian metastasis with huge RCC in a dog.

Renal injuries occur in more than 10% of patients who sustain blunt abdominal injuries. Non-operative management (NOM) is the established treatment strategy for lowgrade (I-III) renal injuries. However, despite some evidence that NOM can be successfully applied to high-grade (IV, V) renal injuries, it remains unclear whether NOM is appropriate in such cases. The authors report two cases of high-grade renal injuries that underwent NOM after embolization in a hybrid emergency room (ER) system with a 24/7 in-house interventional radiology (IR) team. A 29-year-old male visited Wonkwang University Hospital Regional Trauma Center complaining of right abdominal pain after being hit by a rope. Computed tomography (CT) was performed 16 minutes after arrival, and the CT scan indicated a grade V right renal injury. Arterial embolization was initiated within 31 minutes of presentation. A 56-year-old male was transferred to Wonkwang University Hospital Regional Trauma Center with a complaint of right flank pain. He had initially presented to a nearby hospital after falling from a 3-m height. Thanks to the key CT images sent from the previous hospital prior to the patient's arrival, angiography was performed within 8 minutes of the patient's arrival and arterial embolization was completed within 25 minutes. Both patients were treated successfully through NOM with angioembolization and preserved kidneys. Hematoma in the first patient and urinoma in the second patient resolved with percutaneous catheter drainage. The authors believe that the hybrid ER system with an in-house IR team could contribute to NOM and kidney preservation even in high-grade renal injuries.

목적: 소아에서 드문 질병인 급성 세균성 신엽염의 질병 성격을 살피기 위하여, 9명의 환아를 대상으로 발현 증상, 임상 경과, 치료 반응, 동반 요로 기형, 신장 손상 정도 등을 조사하였다. 방법: 1994년 9월부터 2004년 8월까지 복부 초음파 또는 복부 컴퓨터 단층 촬영을 통하여 신엽염으로 확진된 9명의 환아를 대상으로 진료 기록을 후향적으로 분석하였다. 결과: 대상 환자들의 연령분포는 1개월에서 6세까지 평균 $2.8{\pm}2.2$세였으며, 성별로는 남자 6명 여자 3명이었다. 발열 및 오한은 모든 환자에서 있었고, 그 외 복통, 배뇨곤란 및 빈뇨가 있었다. 내원 당시 시행한 검사실 검사상, 백혈구수 $21,000{\pm}5,600/uL$, ESR $60{\pm}23mm/hr$, CRP $17{\pm}10\;mg/dl$이었으며. 혈액 배양 검사는 모두 음성이었다. 소변 검사상, 농뇨 및 현미경적 혈뇨는 모든 환자에게 있었고, 치료후 농뇨가 소실되기까지 $10.5{\pm}7.8$일이 소요되었다. 복부 초음파 검사상, 신장에 국소적으로 경계가 불명확하면서 에코가 떨어져 있는 신엽염 소견이 5명(55.5%)에서 관찰되었다. 복부 컴퓨터 단층 촬영에서는 불명확한 경계를 띠고 조영제에 증강이 잘 되지 않는 쐐기 모양의 신엽염의 소견이 모든 환자에서 관찰되었다. 방광요관역류는 3명(33.3%)에서 있었으며, 모두 3단계 이상이었다. $^{99m}Tc-DMSA$ 스캔에서는 일측 또는 양측 신장의 피질 손상이 확인되었다. 4개월 후 추적한 스캔상, 6명중 2명(33%)은 이전에 비해 병변의 크기가 감소되었으나, 나머지 4명(67%)은 병변의 크기가 불변 또는 약간 악화된 소견이었다 환아의 총 발열기간은 $11.8{\pm}6.3$일로, 이중 입원전 기간은 $4.0{\pm}3.0$일, 입원후 기간은 $7.8{\pm}5.5$일이었다. 입원 기간은 7일에서 31일까지 평균 $17.2{\pm}8.1$일이었다. 결론: 요로감염 환아에서 치료 후에도 1주이상 발열, 농뇨, 높은 혈액 염증 수치가 지속될 경우 '급성 세균성 신엽염'을 적극 의심하여야 하며, 질환의 정확한 진단을 위하여 신장 초음파검사 보다는 컴퓨터 단층 촬영을 우선 실시할 것을 제안하는 바이다.

We describe a case of a 61-year-old Korean man who was diagnosed with renal cell carcinoma that was discovered on abdominopelvic computed tomography obtained after the patient complained of back pain. A radical nephrectomy was performed, and the surgical specimen showed a relatively well-circumscribed and yellowish lobulated hard mass. Microscopically, the tumor showed sheets and nests of hypercellular pleomorphic cells with thick fibrous septation, frequent mitoses, and areas of adrenal cortical-like tissue. Immunohistochemical staining revealed that the tumor cells were positive for inhibin-${\alpha}$, vimentin, synaptophysin, and melan A. It also revealed that the tumor cells were negative for pan-cytokeratin, epithelial membrane antigen, paired box 8, ${\alpha}$-methylacyl-coenzyme A racemase, CD10, cytokeratin 7, carbonic anhydrase 9, c-Kit, renal cell carcinoma, transcription factor E3, human melanoma black 45, desmin, smooth muscle actin, S-100, chromogranin A, CD34, anaplastic lymphoma kinase, and integrase interactor 1. Based on these histopathological and immunohistochemical findings, we diagnosed the tumor as intrarenal adrenocortical carcinoma arising in an adrenal rest. Several cases of intrarenal adrenocortical carcinoma have been reported, although they are very rare. Due to its poor prognosis and common recurrence or metastasis, clinicians and pathologists must be aware of this entity.

신수질 간질세포 종양은 거의 대부분의 경우에서 부검 혹은 다른 원인에 의해 신장을 절제했을 때 우연히 발견된다. 하지만, 드물게 임상적인 증상을 보이는 신수질간질세포 종양의 경우도 보고되었다. 우연히 발견된 신장 종양으로 나타난 신수질 간질세포 종양이 영상 검사상 신세포종양을 모방하였던 증례를 보고한다.
