• Biphasic squamoid alveolar renal cell carcinoma (BSARCC) is a recently described kidney cancer entity with <60 published cases so far. Some unique features of BSARCC include distinct squamoid and alveolar morphology forming glomeruloid configurations and 2 types of tumor cells with different immunoprofiles. Although the mechanism is unknown, neutrophils and cellular materials engulfed by larger tumor cells (described as “emperipolesis”) are observed in all reported cases including the current one. In this article, we report a case of a 70-year-old man who presented with an incidental renal mass during workup for immunoglobulin M monoclonal gammopathy of unknown significance and cold agglutinin autoimmune hemolytic anemia. A detailed pathologic evaluation and immunohistochemical studies revealed BSARCC colliding with atypical CD5+ monoclonal B-cells.
