我还见过两个误诊:一个是肺的 Chondroid hamartoma 诊断为肺癌,大体结果出来后,重看细胞学标本发现有软 骨成份。另一个是在 Salivary gland 的 FNA 中诊断为 Squamous cell carcinoma ,切除后发现是Warthin's tumor ,重看细胞学发现背景有很多的淋巴细胞。 从另一方面来讲细胞学要比组织学难得多,比如在 CBD 中取出的少许细胞临床要你诊断是否有癌时,等等。 |

Based on cytology morphology ----- the aspiration is cellular but cohasive tissue fragments which is benign looking with naked bipolar nucleus background. some ductal cells show some nuclear atypia and atypical formation but not enough to call something even "suspicious for malignancy". For me, it's benign. very beautiful images! Thank you for the interesting case. |
以下是引用hay 在2006-11-21 11:12:00的发言: False negative diagnoses range from 5% to 20%. Not all breast lesions can be diagnosed accurately by FNA biopsy. Bland, well-differentiated, or small cell tumorscan be difficult to diagnose by cytology.We need "Triple Test" ----- clinical finding + mammography + FNA biopsy for patient's treatment. |
