AI Article Synopsis
- A 59-year-old woman discovered an incidental tumor in her right kidney during medical exams, which was found to be a solid 8 cm tumor at the lower pole.
- She underwent partial nephrectomy without clamping renal vessels, and histopathological analysis revealed spindle cells with collagen fibers, leading to a diagnosis of a solitary fibrous tumor.
- Three years post-surgery, the patient showed no signs of tumor recurrence or metastasis.
Article Abstract
A 59-year-old woman was referred to our hospital with the finding of an incidentaloma in her right kidney. Computed tomographyand magnetic resonance imaging showed a solid tumor, approximately8 cm in diameter, at the lower pole of the right kidney. Partial nephrectomy was performed without a renal vessel clamp. Histopathologically, fibroblast-like spindle cells were proliferating with rich collagenous fibers, and tumor cells were infiltrated into the renal parenchyma. The tumor cells were stained positive with CD34, CD99, and bcl-2. The tumor was diagnosed as solitaryfibrous tumor originating from the kidney based on these histopathological findings. The patient was followed 3 years after surgery with neither recurrence nor metastasis.
