High power view of the previous image showing hobnail nuclei in some of the tubules of nephrogenic adenoma. The nuclei are hyperchromatic but the chromatin is smudged. Punctate nucleoli can be seen. The stroma contains abundant neutrophils, lymphocytes, and plasma cells. Following features are usually not found in nephrogenic adenomas: increased mitotic activity, significant cytologic atypia, solid areas, and deeply infiltrative pattern.
