| 摘 要： | 目的：探讨黏膜相关淋巴组织（MALT）淋巴瘤中常见的两个染色体易位t（11；18）（q21；q21）／API2-MALT1和t（14；18）（q34；q21）／IGH—MALT1在皮肤MALT淋巴瘤中的发生率。方法：采用MALT1及IGH双色分离探针，对19例皮肤MALT淋巴瘤标本进行间期荧光原位杂交（FISH）。结果：19例皮肤MALT淋巴瘤中均未检测到涉及MALT1基因的染色体易位，但发现2例（2／19，11％）存在MALT1基因的3个拷贝现象。结论：涉及MALT1基因的染色体易位，即t（11；18）（q21；q21）／API2-MALT1和t（14；18）（q34；q21）／IGH—MALT1在皮肤MALT淋巴瘤罕见或不见。

| Abstract: | Objective.t（ll;18）（q21;q21）/API2-MALT1 and t（14;18）（q34;q21）/IGH-MALT1 have been reported in cutaneous MALT lymphoma. However, the incidence of t（11;18）（q21;q21）/API2-MALT1 and t（14;18）（q34;q21）/IGH-MALT1 in this kind of cutaneous lymphoma remains unclear. Methods. 19 cases of cutaneous MALT lymphoma were screened by interphase FISH analysis using MALT1 and IGH break apart probes. Results： The translocations involving MALT1 were not detected in all of the 19 cutaneous MALT lymphoma, but 3 copies of MALT1 gene were detected in two of the 19 cases （11%） . Conclusion：This study demonstrated that translocations involving MALT1 gene, including API2-MALT1 and IGH-MALT1 are absence or at least uncommon in cutaneous MALT lymphoma. |
