Gastric metastasis from renal cell carcinoma with a 10-year interval: A case report

Figure 4 Diagnosis of gastric metastasis from clear cell renal cell carcinoma was confirmed via pathological immunohistochemical analysis of the lesion. A: Microscopic images of pathological sections obtained via endoscopic gastric biopsy [hematoxylin and eosin (H&E), 100 ×]; B: Microscopic images of sections from the gross surgical resection specimen (H&E, 40 ×); C: Postoperative pathological immunohistochemical staining results revealed positivity for PAX-8 (200 ×), carbonic anhydrase IX (200 ×), and CD10 (200 ×), and negativity for cytokeratin 7 (200 ×), which was consistent with the diagnosis of clear cell renal cell carcinoma.
