Introduction:
Castleman’s disease is a benign lymphoproliferative disease, most of them occurred in mediastinum and neck lymph node. Primary involvement of kidney is extremely rare. Image of Castleman’s disease may mimic renal malignancy. We presented a 63 year-old man with left renal mass, and accepted partial nephrectomy. The pathological report consisted with Castleman’s disease.
Case presentation:
A 63-year-old man denied any systemic disease. There was no obvious flank pain, body weight loss or gross hematuria was noted. He was informed having one left renal tumor during health examination. The abdominal magnetic resonance imaging was arranged and one 2.6 cm left renal nodule over upper pole was found. The patient accepted laparoscopic partial nephrectomy for the left renal tumor smoothly. The pathological diagnosis was consistent with Castleman’s disease. The follow up abdominal computed tomography after 6 months revealed no tumor recurrence.
Conclusion:
The incidence of Castleman’s disease is extremely rare. Besides, the radiological features frequently similar to malignancy lesion. Castleman’s disease should be keep in mind as a differential diagnosis of renal tumor, and pre-operative renal biopsy could be considered to prevent unnecessary surgical treatment.
