原发性胃肠道粘膜相关淋巴组织淋巴瘤47例临床病理分析

目的 探讨原发性胃肠道粘膜相关淋巴组织淋巴瘤(GIL-MALT)的临床病理特点。方法 回顾性分析1990～2000年我院经手术及病理证实的47例胃肠道MALT患者临床病理资料。结果 47例患者平均年龄57．2岁，男女比例2．1：1。以腹痛和发热为主。病变分布为胃32例，小肠4例，回盲部及盲肠5例，大肠6例。内窥镜下息内型15例，溃疡型25例，弥漫型7例。除1例为T细胞淋巴瘤，其余均为B细胞淋巴瘤。结论 胃肠道粘膜相关淋巴瘤以中老年为主，男性居多，临床误诊率较高。内窥镜下多次多点活检、深凿活检可提高本病的确诊率。

Clinical and pathological features of primary gastrointestinal MALT lymphoma

Objective To study the clinical and pathological features of gastrointestinal lymphoma arising from muscosa-associated lymphoid tissue(GIL-MALT).Methods Clinical and pathological data of 47 patients with gastrointestinal MALT lymphoma were retrospectively reviewed and analysed.Results MALT patients had a median age of 57.2years with male predominance.Abdominal pain and febrile were two predominant symptoms.The tumor originated from stomach in 32 cases,small intestine in 4,ileocecal region and blindgut in 5,and large intestine in 6.The tumor appeared nodular in 15cases,ulcerative in 25,and infiltrative in 7 by endoscope or colonoscope.All the cases were B-cell lymphomas except one.Conclusions Clinical presentation and endoscope of GIL-MALT easily leacl to wrong diagonosis.Multiple sites and deep bites biopsy can improve the diagnostic accuracy
