血管内淋巴瘤(IVL)是一种独特的播散性恶性淋巴瘤。然而,由于 IVL 极为罕见且在患者活着时难以诊断,因此尚未报道仅限于 IVL 染色体畸变的详细比较研究。我们在此介绍一例 IVL 病例,并将其核型与先前报道的 5 例 IVL 病例进行比较。在我们对 B 细胞谱系典型 IVL 的比较研究中,发现了 1、6 和 18 号染色体结构畸变的积累,特别是 1p(6 例中的 4 例)和 18 三体性(6 例中的 4 例)。这些染色体重排必须提供有关与 IVL 细胞遗传学相关的细胞遗传学特征的重要信息。
Intravascular lymphomatosis (IVL) is a unique, disseminated type of malignant lymphoma. However, no detailed comparative study limited to the chromosomal aberrations of IVL has been reported, because IVL is extremely rare and difficult to diagnose while the patient is alive. We present here a case of IVL, and compare its karyotype with those of five cases of previously reported IVL. The accumulation of structural aberrations in chromosomes 1, 6, and 18, especially 1p (4 of 6 cases) and trisomy 18 (4 of 6 cases), were found in our comparative study of the B-cell lineage typical IVL. These chromosomal rearrangements must provide important information regarding the characteristics of cytogenetically associated with the cellular genetics of IVL.
