The specimen is received in two parts.
Part 1 is labeled "right iliac lymph node", and consists of a 3.5 x 3.0 x 2.5 cm. roughly ovoid, rubbery, firm and partly encapsulated node, with cut surfaces showing tan, homogenous and fleshy tissue. The representative section is frozen. A section is submitted for B5 fixation. Representative portions are submitted for flow cytometry, clinical molecular biology, cytogenetics evaluations, and bulk freezing.
Part 2 is labeled "allograft kidney", and consists of a 180 gram, 10.0 x 7.3 x 4.0 cm. allograft nephrectomy. The capsular surface is slightly bosselated, tan and granular and shows an adherent segment of soft pink tissue possibly representing capsule. The hilus had been previously excavated, showing partly exposed pelvis and no identifiable ureter. The hilar vascular structures are grossly patent. On sectioning, the renal cortex is rubbery, tan and slightly grainy, ranging from 0.6 to 0.9 cm. in thickness, and there are two moderately demarcate, tan-white, cortical lesions, measuring 0.5 and 0.6 cm. in greatest dimension. The medullary pyramids are well demarcated, pink and striated. The pelvis shows smooth, white epithelium, and grossly normal calices. Arterial branches in the deep hilus show focal plaque material, and several are occluded by dense, gray-red thrombus material. Portions of tissue are bulk frozen, and gross photographs and digital images are taken.
