Immunohistochemical analysis identifies papillary renal cell carcinoma associated with tuberous sclerosis complex. (A) Main tumor nodule surrounded by thick fibrous stroma on low power; (B) Prominent papillary architecture lined by large clear cells with delicate eosinophilic cytoplasmic thread-like strands, which occasionally appeared more outstanding and aggregated to form eosinophilic globules on high power. Immunohistochemical analysis revealed positive staining for (C) CK7 and (D) CD10, whereas (E) SDHB and (F) AMACR were negative.
