Analysing 24 cases of gastric sarcomas of hemopoietic origin (22 non-Hodgkin's lymphomas, 2 Hodgkin's disease) and one instance of plasmacytoma, the authors review the general and radiologic characteristics of such uncommon affections. The gastric localizations of plasmocytic affections are rare, and of them, the ulcerated fungating manifestation of the lesser curvature is the most classical. In the course of Hodgkin's disease, the finding of gastric localization darkens the prognosis since it implies a Stage IV. Because of fibroblastic stroma-response, the images are radiologically similar to adenocarcinoma. On the other hand, the radiologic aspect of gastric localization of non-Hodgkin's lymphoma leads to preoperative diagnosis. -- radiologic images measuring at least 10 cm on their long axis in more than two-thirds of cases, -- clinical-radiologic discrepancy (discreet clinical findings and extensive radiologic evidence), -- infrequent stenotic varieties, -- relatively frequent combined forms (one-third of cases) and eventual simultaneous duodenal localization (about 10%).
通过分析24例造血源性胃肉瘤（22例非霍奇金淋巴瘤、2例霍奇金病）及1例浆细胞瘤病例，作者回顾了此类罕见疾病的一般特征和放射学特征。浆细胞性病变的胃部定位很少见，其中小弯侧溃疡性蕈伞样表现最为典型。在霍奇金病病程中，发现胃部定位会使预后恶化，因为这意味着处于IV期。由于成纤维细胞基质反应，影像学表现与腺癌相似。另一方面，非霍奇金淋巴瘤胃部定位的放射学表现有助于术前诊断。——在超过三分之二的病例中，放射学图像长轴至少10厘米，——临床与放射学表现不符（临床症状不明显而放射学证据广泛），——狭窄类型少见，——合并形式相对常见（三分之一的病例）以及最终同时出现十二指肠定位（约10%）。
