Primary adult renal pelvic soft tissue giant cell tumor: A rare case report.

Primary adult renal pelvic soft tissue giant cell tumor: A rare case report.
Pyelonephric giant cell tumor of soft tissue represents an exceptionally uncommon neoplasm of the urinary tract with limited malignant potential.
The present case seeks to augment the clinical dataset and elucidate the features of its malignant transformation.
PATIENT CONCERNS: A 72-year-old male presented with a 3-day history of persistent right-sided low back pain, without fever, gross hematuria, or dysuria.
Contrast-enhanced abdominal computed tomography imaging revealed wall dilation and hypertrophy of the right renal pelvis-ureteral transitional segment with lipomatous enhancement, measuring approximately 3.3 × 2.7 cm.
INTERVENTIONS: The patient underwent radical nephroureterectomy after systematic preoperative evaluation.
Adrenal gland and pulmonary metastatic lesions were detected at 6 months postoperatively.
Postoperative surveillance should be intensified to facilitate early detection of recurrence, as some patients harbor potential relapse, and prognosis remains cautiously guarded.
