Solid Variant of Papillary Cystadenoma of the Epididymis Mimicking Metastatic Clear Cell Renal Carcinoma | Insight Medical Publishing

Papillary Cystadenomas of the Epididymis (PCE) are benign neoplasms of the epididymis. Their appearance can often be confused with that of a metastatic clear cell renal cell carcinoma (clear cell RCC) due to similar appearances under microscopy. Here, we report a case of a 65 year old diabetic male, who presented with a rare solid variant of PCE; whereby normal papillary or cystic structures were absent. We then performed a wider immunohistochemical profile in comparison to a similar case reported in 2014 (Yang, et al.).
