[A case of XXXX with bone formation].

A case of @entity8 with bone formation is reported. A 61-year-old @entity1 was admitted to our hospital with one month history of fever. About 15 cm in diameter mass was palpated in her right lower abdomen. Plain abdominal roentgenography, ultrasonography and computed tomography showed marked @entity730 in the cephalic portion of the right kidney, @entity5 surrounding right kidney and another @entity5 in the right lower abdomen. All these @entity5 and the kidney constituted a big mass continuously, and no fatty component was demonstrated. Total excision of the mass including the kidney was performed. The mass was 30 @entity73121 10 cm in size and 3,240 g in weight. Histologically, the @entity5 was compatible to @entity8 . But, radiopaque shadows which looked like @entity730 were disclosed to be bones, and fatty tissues were not seen so much. Therefore, the name " @entity16048 " was thought to be more acceptable than @entity359 in this case. Preoperative diagnosis of @entity8 is the demonstration of fatty densities in the @entity5 , and the characteristic extrarenal development should also be taken into consideration. Furthermore, the bone formation of @entity359 , which is very rare might be an important finding to @entity359 .
