She was found to have multilocular cyst of the kidney and had surgical treatment. 2) This case seemed to be the twelfth case of multilocular cyst of the kidney in Japan. Classification of the cystic renal diseases was discussed here with review of some literature in order to locate this disease in the correct position of the classification. 3) It was emphasized that histological investigation is further required in this kind of renal disease in order to investigate its pathogenesis. In our case, fibrosis of the cyst wall, scattered tubulus-like glandular structure filled with eosinophilic material and the capillary neogenesis were characteristic.
