摘要
目的总结肠结核内镜活检病理诊断经验,以减少误诊和漏诊率。方法7例肠镜活检标本经抗酸染色确诊为肠结核的病例,复习其HE染色片镜下特点。结果本组7例中炎性渗出和(或)肉芽组织增生3例,其中散在少量类上皮细胞;黏膜内见类上皮细胞结节(微肉芽肿)2例(1例有个别多核巨细胞);仅见散在类上皮细胞1例;黏膜慢性炎伴化脓1例。无1例见到干酪样坏死。结论对于肠镜活检标本,HE染色片中见到炎性渗出、肉芽组织增生、黏膜慢性炎伴化脓时,需仔细寻找是否有类上皮细胞和(或)微肉芽肿,行抗酸染色是必要的,它对肠结核的诊断有重要意义。
Purpose To report the experience of pathologic diagnosis of intestinal tuberculosis by endocopic biospic tissue, and to avoid missed and misdiagnosis. Methods 7 cases of intestinal tuberculosis diagnosed through acid-fast staining were reviewed and analysed morphologically. Results There were seven cases in this group. Some epithelioid cells were scattered in .the inflammatory exudate and/or granulation tissue in 3 cases; There were microgranulomas in tunica mucosa in 2 cases （few multinuclear cells in 1 case） ; only some epithelioid cells were seen in tunica mucosa in 1 case; Chronic suppurative inflammation in tunica mucosa was found in 1 case. There were no caseous necrosis and Langerhan＇ s cells in any case. Conclusions When inflammatory exudate,granulation tissue, chronic suppurative inflammation in tunica mucosa are observed in endoscopic biopsied tissue and HE staining, try to look for the epithelioid cells and/or microgranulomases, in which acid-fast staining is useful and may play an important role in the diagnosis of intestinal tuberculosis.
