A case report of huge solitary fibrous tumor of kidney / 中华泌尿外科杂志

Solitary fibrous tumor is a rare mesenchymal tumor associated with NAB2-STAT6 fusion gene, which is rarely seen in kidney. A 16-year-old boy was hospitalized because of left back pain for more than 3 years. Abdominal CT/MRI identified a huge space-occupying lesion in the left kidney. Laparoscopic radical left nephrectomy was performed initially. Nevertheless, laparoscopic-to-open procedure was adopted due to the huge size of the tumor. The pathological diagnosis was renal solitary fibrous tumor. The symptoms of the patient disappeared and no recurrence was observed at the 2-month follow-up after the surgery.
