Zusammenfassung

Die seltenen gutartigen Tumoren der Niere umfassen eine Gruppe histogenetisch sehr verschiedener Entitäten. Wir berichten über eine 53-jährige Patientin, bei der aufgrund des Verdachts auf Vorliegen eines Nierenzellkarzinoms eine laparoskopische Nephrektomie durchgeführt wurde. In der histologischen Untersuchung zeigte sich der seltene Befund eines benignen metanephrischen Adenoms. Das hier beschriebene metanephrische Adenom stellt mit weniger als 200 dokumentierten Fällen eine Rarität im urologischen Alltag dar und ist klinisch sowie bildmorphologisch ohne histologische Begutachtung derzeitig nicht von einem malignen Tumor der Niere zu unterschieden.

Abstract

Rare benign tumours of the kidney comprise a group of very different histogenetic entities. We report a case of a 53-year-old woman who underwent laparoscopic nephrectomy because of a renal mass. The diagnosis of a rare and benign metanephric adenoma was confirmed by histopathology. With less than 200 documented cases, the metanephric adenoma described here is a rarity in everyday urological practice and cannot be distinguished from a malignant tumour of the kidney by clinical examination and/or imaging without histological assessment.
