A The left lung squamous cell carcinoma (SCC) specimen obtained after resection by video-assisted thoracic surgery. Histological findings of the specimens obtained after robotic-assisted partial nephrectomy. B Clear cell carcinoma in the resected left primary renal tumor. Most cancer cells were classified into WHO/ISUP nuclear grade 2, but C there were also some partially grade 3 cancer cells. Hematoxylin–eosin stain (HE), reduced from 100 ×
