Composite oncocytoma and papillary renal cell carcinoma of the kidney treated by partial nephrectomy: a case report.

We present the case of a 73-year-old woman who presented with lethargy and a nonproductive cough. Computerised tomography of her abdomen revealed a 38-mm mass in the lower pole of her left kidney. She underwent a partial nephrectomy, with final histopathological analysis confirming the presence of a concomitant oncocytoma and papillary cell carcinoma.

An unusual case of low-grade tubulopapillary adenocarcinoma of the sinonasal tract.

Background: Low-grade papillary adenocarcinomas of the sinonasal tract are rare neoplasms. Over recent years, little doubt remains that this tumour represents a separate entity based on morphology, ultrastructural features and behaviour. We outline a case of this rare entity displaying a not hitherto described immunophenotype.
