Although stomach is a frequent site of extranodal lymphomas, histiocyte-rich TCRBCL has not yet been described there. Even histology of repeated gastrobiopsies of this uncommon, diffuse, large B-cell lymphoma may be inconclusive and partial gastrectomy cannot be avoided. It is only immunohistology (CD20, CD43, CD68) of the paraffin blocks from the resection specimen that can lead to the final diagnosis of intermediate grade malignant lymphoma.
尽管胃是结外淋巴瘤的常见部位，但富含组织细胞的 TCRBCL 尚未在那里描述过。即使对这种罕见的弥漫性大 B 细胞淋巴瘤进行重复的胃活检，其组织学也可能没有定论，而且不能避免部分胃切除术。只有切除标本的石蜡块的免疫组织化学（CD20、CD43、CD68）才能导致中间级恶性淋巴瘤的最终诊断。
