[Rectal hemorrhage as a first sign of renal cell adenocarcinoma].

Renal cell carcinoma accounts for 85% of all renal primary tumours, the remaining 15% tumours originating either in the renal pelvis or the renal capsule. Clinical signs and symptoms of renal adenocarcinoma can be classified in four groups: specifically urological signs and symptoms, unspecific general symptoms, paraneoplastic syndromes, and metastasis-derived symptoms. The classical triad consists of haematuria, pain and palpable abdominal mass; at present this triad appears in a minority of cases, and is usually a late finding. The number of cases diagnosed from unspecific signs and symptoms is increasingly larger. Routine use of ultrasound and CAT allows a higher number of diagnosis, which frequently occur in the less advanced stages. The present paper presents a case report of renal cell adenocarcinoma, diagnosed from an infrequent early symptom such as rectal bleeding.
