Case description (by case creator):
Incidentally found 1.9 cm renal mass in a 67 year-old female, partial nephrectomy specimen. The tumour is characterized by papillary architecture and cells with abundant granular eosinophilic/oncocytic cytoplasm. The tumour cells have ISUP grade 3 nuclei and cover the papillary fronds generally as a single layer. Many of papillary fronds are distended by foamy histiocytes. The features are those of a papillary renal cell carcinoma with oncocytic features, NOS (neither Type 1 or Type 2 by current convention).
