Synchronous ipsilateral adrenocortical carcinoma and renal cell carcinoma: a rare clinical entity.

Synchronous ipsilateral adrenocortical carcinoma (ACC) and renal cell carcinoma (RCC) are rare. Radiological imaging may not in all cases differentiate between the two tumours due to their proximity to each other. We encountered a case where preoperative diagnosis of renal cell carcinoma was made based on the radiological imaging but, following radical nephrectomy, this was found to be synchronous ACC and RCC after histopathological examination. The patient is doing well at 12 months of follow-up, with no clinical or radiological recurrence.
