Fig. 5From: Using short tandem repeat analysis for choriocarcinoma diagnosis: a case seriesPelvic choriocarcinoma with concurrent third trimester placenta (case #10). Genotyping demonstratesthat the tumor is purely androgenetic/homozygous XX, with different homozygous alleles in D16S539 compared with the placenta and different D3S1358 and D13S317alleles compared to the maternal sample, indicating that different sperm were involved in the tumor and the placentaBack to article page
