Hilar Nodes : Single lymph node measuring 0.4x0.4 cm. Fibrofatty tissue measuring 1x1 cm, submitted entirely. Left Periportal node: Single lymph node measuring 0.5x0.4 cm. Fibrofatty tissue measuring 1x1 cm, submitted entirely. Hepatic Artery Nodes: No lymph node identified. Fibrofatty tissue measuring 0.5x0.5 cm, submitted entirely. Right Periportal node: No lymph node identified. Fibrofatty tissue measuring 1x0. 5x0.5 cm, submitted entirely. Cystic Duct Margin: Received single soft tissue bit measuring 3x1x0. 9 cm. ?Ink identified at end of the ?duct like structure. Representative section submitted entirely. Tissue is submitted entirely. Sections: 1-3) Liver Wedge, 4) Hilar Nodes, 5) Left Periportal node, 6) Hepatic Artery Nodes, 7) Right Periportal node, 8) Intra Aortocaval Nodes, 9-11) Cystic Duct Margin (9 with cut margin). Grossed by: Dr. Prranjali Microscopic Description Liver wedge resection (Post chemotherapy): No residual tumour seen. Focal foreign body giant cell reaction seen. Hilar Nodes : Two reactive lymph nodes (0/2). Left Periportal node : Two reactive lymph nodes (0/2). Hepatic Artery Nodes : No lymph nodes identified. Unremarkable fibrofatty tissue only. Right Periportal node: Single reactive lymph node (0/1). Intra-aortocaval nodes : No lymph nodes identified. Unremarkable fibrofatty tissue only. Total lymph node 0/5. Separately sent, Cystic Duct Margin is unremarkable. Periductal tissue shows suture granuloma. Impression Liver wedge resection (Post chemotherapy): No residual tumour with reactive regional lymph nodes. TNM What is the meaning of this?
