Diagnosis of Recurrent Renal CellCarcinoma Following Segmental and LaparoscopicResection of Multiphase Spiral Computerized Tomography

摘要

A 61-year-old man presented with a history of segmental and laparoscopic resection of a renal cell carcinoma (RCC) in June and July 2000, respectively. An encapsulated papillary renal RCC, 3 cm in greatest dimension, located in the mid pole of the right kidney was resected laparoscopi-cally. The inked margins were within 1 mm of the 3 X 1.5 X 2 cm tumor. A clear cell type RCC, 6.5 cm in greatest dimension, Fuhrman nuclear grade 2-3, was removed by segmental resection from the upper pole of the left kidney. Although the excision margins were free of disease, vascular invasion was identified in condensation of fibrous tissue. The left tumor exhibited different histology than the right papillary RCC.
