Guest bean_si (Not Active) Posted May 29, 2004 Share Posted May 29, 2004 I posted under General, topic WRONG DIAGNOSIS but I thought I would post here to see if anyone with NSCLC has received this diagnosis. Please notice comment. M.D. Anderson DIAGNOSIS POORLY DIFFERENTIATED CARCINOMA, FAVOR NON-SMALL CELL CARCINOMA (See Comment) COMMENT: Submitted immunohistochemical stains are reviewed and the results are as follows: cylokeratin 7-positive, cytokeratin 20-negative, Kermix-focally positive, CD56 positive The finding of CD56 suggests neuroendocrine differentiation. This raises the possibility of a possible large cell neuroendocrine carcinoma. --------------------------------- Original Diagnosis from local hospital DIAGNOSIS: RIGHT UPPER LOBE OF LUNG MASS BIOPSY: SMALL CELL CARCINOMA OF LUNG (SEE COMMENT) COMMENT: The tumor cells are immunoreactive for CK7, CD56 and negative for CK20, LCA. This immunostaining profile is consistent with a small cell carcinoma of lung primary." Cat Quote Link to comment Share on other sites More sharing options...
