A retroperitoneal metastasis from malignant melanoma is an uncommon event and mostly secondary to a primary lesion of the posterior trunk. We report on a 38-year-old patient with malignant melanoma of the anterior trunk who presented a symptomatic metastatic mass of the left renal hilum not originating from the retroperitoneal lymph nodes of the renal hilum, surrounding and infiltrating the renal pelvis, treated with left nephrectomy, complete mass excision and regional lymph node dissection. The patient later developed also brain metastases and is now undergoing immunotherapy.
