胃溃疡偶可伴有胃壁淋巴组织肿瘤样反应性增生——假性淋巴瘤(Pseudolymphoma),但很少被注意。这种改变,在术前X线检查和手术中检查时易被误认为癌瘤,在胃标本病理检查时,易被误诊为恶性淋巴瘤。故明瞭此种病变具有重要意义。我们最近见到两例,报道如下。 Gastric ulcers may be accompanied by tumor-like reactive hyperplasia of the gastric wall lymphoid tissue - pseudoneoplastic lymphoma (Pseudolymphoma), but it is rarely noted. This change can easily be mistaken for cancerous tumors during preoperative X-ray examinations and intraoperative examinations, and can easily be misdiagnosed as malignant lymphomas during gastric pathological examinations. Therefore, it is important to understand this type of lesion. We have seen two cases recently and the report is as follows.
