Abstract
Renal lipoma is a very rare tumor that has only been described in about twenty cases in adults and in a single case in a child aged 2 years. This paper presents a renal lipoma in 63 year old female patient. The tumor size of 7.5×4.5 cm was located in her right kidney, clearly delineated from the surrounding kidney tissue, and histology was completely built of mature adipose tissue. This paper describes the case of a rare benign lipoma which histogenesis is yet not clearly understood.
