A case of angiomyol***ipoma of the kidney with the involvement of regional lymph nodes and adjacent adipose tissue is reported. Histology of the tumor was essentially benign in either location. During three years of follow‐up period, no recurrence or distant metastasis has appeared. It was considered that the tumor was benign and that the regional lymph node involvement probably represents a multicentric hamartomatous or choristomatous growth. In such an example, it is suggested that additional treatment such as radiation or chemotherapy should be avoided until a definitive evidence of distant metastasis is obtained.
