Diarrhea secondary to intestinal infiltration secondary to renal epidermoid carcinoma.

Renal squamous cell carcinoma is a rare neoplasm in adults, but with an aggressive behavior. It is diagnosed in most cases in advanced stages. The invasion of the digestive tract by this type of tumor is rare, due to the anatomical arrangement of the colon, however, when it occurs, it carries a poor prognosis for the patient. Digestive endoscopy allows us to reach a definitive diagnosis since these patients usually present digestive manifestations, such as diarrhoea, digestive bleeding or abdominal pain.
