[Multilocular cystic nephroma. Report of three new cases]. / Nefroma quístico multilocular. Aportación de 3 nuevos casos.

ABSTRACT

OBJECTIVE: To analyze the presentation of multilocular cystic nephroma and its diagnostic-therapy scheme. METHODS: We report the three last new cases presenting in our department in a period of three years. RESULTS: Multilocular cystic nephroma is a benign lesion, rare that appears both in adult age, generally asymptomatic, and in children, frequently as a palpable mass. Differential diagnosis with malignant tumours is required. CONCLUSIONS: The great variety of clinical presentations, differential diagnosis and places of origin of the cases is demonstrated, being this a reflection of our daily medical practice, in which we cannot reach definitive diagnosis with imaging tests, being the Bosniak's classification very useful for the setting of indication for surgery, which will give definitive diagnosis of multilocular cystic nephroma or what is more important will rule out malignancy.
