* 投稿摘要: Chimerism is a condition with two sets of genetic materials from different zygotes presenting in one person. This situation might be acquired, via transfusion or transplant from donor cells to the recipient. Rarely, it may be congenital, following fusion of two zygotes, so-called tetragametic chimerism. In the following, we report the first case in Taiwan as we know. This was a 6-year-old boy presenting with headache, vomiting, and ataxia. Computed tomography showed a huge cerebellar tumor, and the pathology of biopsy revealed medulloblastoma. Cerebellar tumor tissue was sent for cytogenetic study. During cell culture, two types of cells were harvested with one floating tumor population and the other adherent, fibroblast-like population. All floating cells were tetraploid with mixed clonal changes, which showed 72~85,XXYY,-1[8],dup(1)(q21q42)[2],-2[8],-3[8],+4[3],+6[7],-7[7],-8[8],+9[7],add(9)(q34)×3[7],add(10)(q22)×2[7],-12[8],-12[4],-13[8],-14[6],idic(17)(p11.2)×2[6],-18[5],-20[8],-21[3],+mar1[4],+mar2[4][cp8], corresponding to medulloblastoma molecular subgroup C. The adherent population revealed 7 cells with 46,XX and 4 cells with 46,XY. Peripheral blood was also sent for analysis, which revealed 46,XY, a normal male karyotype. The patient did not have transplant history. Transfusion alone was unlikely to result in the chimerism of tissue. Judged by the heterochromatin patterns of chromosomes, a tetragametic chimerism is considered.
