目的对细针针吸病理细胞学(以下简称FNAC)诊断并经临床确诊的体表淋巴结结核患者,评价未液化坏死(结节型及浸润型)、液化坏死(脓肿型及窦道型)细针吸取标本抗酸染色涂片及罗氏培养(结核分枝杆菌培养)的阳性率。方法对1129例体表淋巴结结核患者细针吸取标本,其中未液化742例、液化387例,行抗酸染色涂片及罗氏培养检查。结果未液化标本中抗酸染色涂片阳性8例,阳性率1.08%,罗氏培养阳性19例,阳性率2.56%;液化标本中抗酸染色涂片阳性101例,阳性率26.10%,罗氏培养阳性152例,阳性率高达73.64%。结论结节型、浸润型淋巴结结核细针针吸标本抗酸染色涂片及罗氏培养阳性率极低,而脓肿型、窦道型细针针吸标本抗酸染色涂片阳性率较高,罗氏阳性阳性率则更高,应积极开展。
Objective To evaluate the diagnostic value of non-liquefied necrosis (nodular and infiltrating type), liquefaction necrosis (abscess type and sinus type) in patients with surface lymph node tuberculosis diagnosed and diagnosed clinically by fine needle aspiration cytology (FNAC) Needle aspiration specimens were stained with anti-acid and Roche culture (Mycobacterium tuberculosis culture) positive rate. Methods A total of 1129 patients with tuberculosis of the body surface lymph node were taken fine needle specimens, of which 742 had not been liquefied and 387 had liquefaction. Acid-resistant stained smears and Roche culture tests were performed. Results In the non-liquefied specimens, 8 cases were positive for acid-fast staining, the positive rate was 1.08%, and the positive rate was 2.56%. The positive rate of acid-fast staining in liquefaction specimens was 101%, the positive rate was 26.10% 152 cases, the positive rate as high as 73.64%. Conclusions The positive rates of nodular and infiltrating lymph node tuberculosis fine needle aspirate anti-acid stained smear and Roche culture are very low. However, the positive rate of abscess type and sinus needle needle aspirate anti-acid stained smear is very high. Roche The positive rate is higher, should be actively carried out.
