Abstract
BACKGROUND
Primary renal Ewing’s sarcoma (ES) is extremely rare, and only two cases causing Cushing’s syndrome (CS) have been reported to date. We report that the case of an 18-year-old patient is diagnosed primary renal ES with typical CS characterized by purple stripes, weight gain, and hypertension.
CASE SUMMARY
CS was first diagnosed by laboratory testing. A huge tumor was revealed in the kidney following an imaging examination. Moreover, brain and bone metastases were observed. After comprehensive treatment, primarily based on surgery, primary renal ES was pathologically diagnosed with a typical EWSR1-FLI1 genetic mutation through genetic testing. Furthermore, the glucocorticoid level returned to normal. By the ninth postoperative month of follow-up, the patient was recovering well. Cushing-related symptoms had improved, and a satisfactory curative effect was achieved.
CONCLUSION
Primary renal ES, a rare adult malignant tumor, can cause CS and a poor prognosis.
Core Tip: Primary renal Ewing's sarcoma (ES), a rare adult malignant tumor, can cause Cushing syndrome and a poor prognosis. The "gold standard" for diagnosing primary renal ES remains pathological examination, even though gene studies can aid in diagnosis and therapy planning. When treating advanced metastatic primary renal ES, a comprehensive surgical approach centered on surgery can produce specific outcomes.
