Beschreibungen/Notizen

• Renal hybrid tumors (HT) are characterized by the association of both oncocytes- and chromophobe-cells within the same tumor. They have been reported in patients with Birt-Hogg-Dube (BHD) syndrome. The aim of this report was to describe two cases of HT and summarize recent literature. Case study was summarized from the patient's medical chart. Review of literature was performed using the National Center for Biotechnology Information (NCBI) database. Two patients were diagnosed with multiple but small tumors of the kidney, and were treated with partial nephrectomy. Pathological analysis of these tumors showed oncocytoma-like and chromophobe-like cells intermixed in the same stroma. HT may constitute a spectrum of tumors between renal oncocytoma and chromophobe renal cell carcinoma. From a pragmatic management perspective, it would be appropriate to consider such tumors as chromophobe carcinoma. In case of HT, a genetic study for BHD syndrome can be proposed to family relatives.
