A rare pericytic tumor of the kidney: the first case in Korea
CONCLUSIONWe described the first case of renal pericytic tumor, addressing uncertain malignant potential, in a Korean male, which would be a distinct mesenchymal neoplasm differentiating from other groups of perivascular tumor families based on histological and immunohistochemical features.
ConclusionWe highlight here the challenge to make the difference between a primary gallbladder carcinoma and metastasis from RCC. Diagnosis is made on pathological examination and immunochemistry.
Conclusions: In this sample of surgically resected tumors, CEUS was effective in characterizing renal lesions as solid neoplasms or complex cystic lesions suspicious for neoplasm-findings which merit further investigation. PMID: 31549563 [PubMed - as supplied by publisher]
CONCLUSION: RPN with a standard laparoscopic ultrasound probe is safe, effective and feasible in treating endophytic renal tumor. Our original approach for separating renal mass can avoid some problems caused by the standard laparoscopic ultrasound probe. PMID: 31350090 [PubMed - as supplied by publisher]
We present a case of retroperitoneal lipogranuloma mimicking metastases of renal cell carcinoma (RCC) after laparoscopic partial nephrectomy. A 63-year-old man who underwent laparoscopic left partial nephrectomy for RCC one year earlier had developed a left retroperitoneal tumor during postoperative surveillance. The tumor looked identical to an implant or recurrence of RCC on contrast-enhanced computed tomography (CT) and 18F-fluorodeoxyglucose positron emission tomography/CT. We resected the tumor, and pathology showed a lipogranuloma.
This report suggested that fibroblast proliferation may be an intermediate status in oncogenesis of IMT, but further investigation is necessary in order to better clarify the relationship between fibroblast proliferation and IMT. The preoperative diagnosis of renal IMT remains difficult. Preoperative fine-needle aspiration or percutaneous biopsy and intraoperative frozen section were applied to confirm the diagnosis to avoid unnecessary nephrectomy, especially in patients with renal insufficiency, bilateral masses, or a solitary kidney.
ConclusionsHere we report a rare case of port site metastasis that was successfully treated 7 years after laparoscopic nephrectomy.
Conclusions: Compared to the extension of RCC to the renal vein or IVC, extension of TCC to the renal vein or IVC is rare. TCC with a venous tumor thrombus is often misdiagnosed as RCC. However, a correct preoperative or intraoperative diagnosis is of great importance to decide surgical strategy. Laparoscopic radical nephroureterectomy with thrombectomy may be a safe and feasible operative method in treatment of TCC with a renal vein thrombus. The prognosis of such cases is poor even if chemotherapy and radiotherapy are scheduled.
Abstract The prognostic role of chromophobe renal cell carcinoma (ChRCC) is still controversial. Here, we report on a patient who lived with tremendous non-progressed renal malignant tumour for eight years. The 32-year-old patient presented to our hospital with a huge renal tumour. Computed tomography (CT) scan showed a tumour 12 cm in diameter at the upper pole of the right kidney. Trans-abdominal laparoscopic right radical nephrectomy was performed. Histopathological examination confirmed this tumour to be a ChRCC. The phenomenon of long-term non-progressed renal malignant tumour will help us further understand ...
CONCLUSIONS: The data show an improved adherence to the guidelines for RCC as measured by quality indicators and a steady process of earlier detection of patients with RCC. PMID: 26202573 [PubMed - in process]
We report on a 44-year-old male patient with cystic angiomyolipoma (AML) simulating cystic renal cell carcinoma on computed tomography (CT). The CT scan showed a 2.8-cm left renal cystic mass with an enhancing solid component. No fat density was identified in the mass. These findings were indicative of a cystic renal cell carcinoma. Robot-assisted laparoscopic partial nephrectomy was performed, but the final histologic result was a cystic AML. Herein, we would review the preoperative CT findings, which could have suggested cystic AML.
