ABSTRACT

Introduction :The oncocytoma and paraganglioma are rarely encountered neoplams than can be diagnosed with certainly only by electron microscopy.

Material and methods: We reported a 39 year-old woman with 2 months of low abdominal pain, pirosis, regurgitation, and abdominal tumor since at 3 years. The tumor with size of 25 cm was fixed and unpain., headache, loss weight by 10 kg. and left lymph node. Hyperthension of 150/110 sometimes. X-ray films revealed a mass distorting the left kidney with hidronefrosis and calcification.

Result: Surgical treatment identified two tumors: the large mass was a Benign oncocytoma of kidney and the little mass was a abdominal paraganglioma. The report and analysis of macroscopic, light microscopy and tramission electron microscopy are discussed in full study.

Discussion: The oncocytoma is identified in light microscopy by their abundant, finely granular acidophilic cytoplams and in electron microscopy by their abundants mitochondrias.
