Computed tomography of renal oncocytomas.
A retrospective analysis of 5 renal oncocytomas studied with CT was performed. Oncocytomas appeared as rounded hypodense solid masses with sharp margination from the normal renal parenchyma. They showed uniform homogeneous enhancement on CT scans performed after drip infusion of urographic contrast. One oncocytoma studied with dynamic CT scanning demonstrated a stellate (spoke-wheel) pattern of...
متن کامل[A case of bilateral oncocytomas of the submandibular gland and synchronous renal oncocytomas].
A case of 42 years-old man with bilateral big sized (12 x 5 cm and 10 x 4,5 cm) oncocytoma in submandibular glands was presented. Oncocytoma is a rare benign neoplasm observed in numerous of organs. In the case described besides submandibular glands tumours, accessory oncocytic tumours in both kidneys were diagnosed. It was the reason of earlier unilateral nephrectomy. Surgical treatment was ap...
متن کاملFamilial and sporadic renal oncocytomas--a comparative molecular-genetic analysis.
OBJECTIVES Genetic causes of sporadic and familial renal oncocytomas are not known. We analyzed these tumors genetically in order to detect tumor-specific chromosome alterations. METHODS DNA from 26 sporadic and 31 familial renal oncocytomas were screened by comparative genomic hybridization according to standard protocols including degenerate oligonucleotide-primed PCR. RESULTS Chromosome ...
متن کاملMitochondrial complex I is deficient in renal oncocytomas.
Renal oncocytomas are benign tumors characterized by dense accumulation of mitochondria the cause of which remains unknown so far. Consistently, mitochondrial DNA content and the amounts and catalytic activities of several oxidative phosphorylation (OXPHOS) complexes were known to be increased in these tumors, but it was not ascertained that the OXPHOS system was functional. Here we investigate...
متن کاملBilateral benign renal oncocytomas and the role of renal biopsy: single institution review
BACKGROUND The goal was to assess the natural history and management of patients with pathologically proven bilateral (synchronous) RO after undergoing initial partial nephrectomy (PN). METHODS All patients underwent either robotic/laparoscopic or open PN by two experienced genitourinary oncologists from 2005-2013. Final pathology was determined by surgical excision, CT-guided percutaneous co...
