DNA ploidy analysis and cell profliferation in congential sacrococcygeal teratomas

DNA ploidy and cell proliferation were analysed by flow cytometry, and the expression of PCNA and Ki67 were analysed immunohistochemically on paraffin embedded tissue. All the tumors that were surgically treated within 3 months after birth, including immature teratoma, were diploid. Strongly positive PCNA immunostaining was found in both immature teratomas, and weakly postive PCNA was found in nine cases. Weak positivity for Ki67 was observed in 2 cases, and moderate positivity was observed in 6 cases including mmature teratomas
