Granulomata in Clear Cell Renal Cell Carcinoma: An Uncommon Presentation of a Common Cancer, Not Two Separate Entities

Sarcoidal-like granulomata (SLG) are known to occur as a response to a variety of tumor types, including lymphomas, prominently seminoma, other miscellaneous carcinomas, and rarely in renal cell carcinoma. There have been a handful of previously reported cases in the literature of SLG occurring in a...

Sumario:Sarcoidal-like granulomata (SLG) are known to occur as a response to a variety of tumor types, including lymphomas, prominently seminoma, other miscellaneous carcinomas, and rarely in renal cell carcinoma. There have been a handful of previously reported cases in the literature of SLG occurring in association with RCC. Of those previously reported, none were associated with infection and only 3 patients had a history of sarcoidosis. The prognostic significance of SLG in RCC is unsettled and somewhat complicated by the relative rarity of its occurrence and the paucity of data therein. A case is presented of an otherwise histologically typical clear cell renal cell carcinoma with peri-tumoral and intra-tumoral SLG. Special stains were negative for organisms and past medical history was negative for sarcoidosis and connective tissue disease.
