One of the commonest defects of blastogenesis is monozygotic twinning resulting in separate or conjoint twins, the latter including a category of internal, "endoparasitic," or fetus-in-fetu twins. We report the third known instance of endoparasitic twinning associated with a benign teratoma at age 1. The host, twin, and teratoma were monozygotic by DNA analysis.
blastogenesis最常见的缺陷之一是单卵孪生，导致形成分离或联体双胞胎，后者包括一类内部的“内寄生性”或胎内胎双胞胎。我们报告了第三例已知的与1岁时的良性畸胎瘤相关的内寄生性孪生病例。通过DNA分析，宿主、双胞胎和畸胎瘤是单卵的。
