To report a case of tubulocystic renal carcinoma diagnosed in an adult, after a work up study for hematuria.59-year-old male, CT scan was performed during a study for self-limited hematuria showing a 4.2 cm solid mass with areas suspicious of pseudocystic malignancy. Due to its debut with hematuria and renal sinus involvement laparoscopic radical nephrectomy was performed, establishing the diagnosis of tubulocystic carcinoma (low grade collecting duct carcinoma).Tubulocystic carcinoma presents histological characteristics and a natural history that makes it different from the classic type of Bellini duct carcinoma, the latter being a rapidly growing tumor with poor prognosis which is usually diagnosed in advanced stages.
