Benign renal angiomyolipoma with regional lymph node involvement. Report of a case showing enlargement five years after nephrectomy.
A case of renal angiomyolipoma followed by massive enlargement of the angiomyolipoma in regional lymph nodes five years after nephrectomy is reported. On the basis of its histology and the absence of distant metastasis, we considered this to be a benign, hamartomatous, and multicentric lesion. Considering the rather rapid growth, however, this case raises some questions with regard to the treatment of this condition, i.e., whether removal of a renal angiomyolipoma should be accompanied by lymphadenectomy, and whether the lymph nodes should be carefully scrutinized by CT scanning or echography preoperatively.
